This Company In Brief

In business in the U.S. since 2008, Isen­berg Bath imports good quality fau­cets primarily from China. Some of its critical components, however, including ceramic cartridges and aerators are supplied by European companies.

The faucet collection is well thought out and artfully coordinated and the components used in the fau­cets, especially the ceramic cartridges and aerators, are some of the best available.

The faucets are of generally good to excellent quality using top-line components. For the price, they are a good value backed by a strong warranty.

Infinity Wall-Mounted Lavatory Faucet

Good DesignThe innovative IF.1000 Infinity wall-mounted lavatory fau­cet has won several design awards including a Good Design award from the Chicago Athenaeum Museum of Architecture and Design in 2020.
Good Design is the oldest and most prestigious of the international juried awards for product design.

Isenberg is unceasingly innovative, selling well-designed, well-made fau­cets for a fair price primarily through design studios and plumbing outlets but also over the internet.

A substantial and growing number of its fau­cet are in-house designs, including at least one fau­cet that has won international design awards.

The Company

The company started in India as Isen­berg India Pvt. Ltd., importing and selling up-scale sanitary wares, including fau­cets, to the sub-continent.

Isenberg Bath, founded in 2008, was, for a short time, structured as an offshoot of the Indian firm. At present, however, the two companies are separate enterprises and do not appear to have any common ownership or financial ties.

Isenberg Bath is organized as a Texas corporation to sell fau­cets, showers, tub fillers, and bath accessories. The current corporation dates from 2012. Texas tax records identify Abbas Poonawala as the corporation's sole officer.

Isenberg Business Model

Isenberg's faucets are divided into two categories:

All of its fau­cets are purchased already assembled with the possible exception of ancillaries such as cartridges, handles, trim, and baseplates.

Any additional assembly performed by Isen­berg to attach handles, insert cartridges, and the like is incidental, and does not rise to the level of assembly required to be considered an .

For a fau­cet to be identified as As­sem­bled in U.S.A., it must meet two conditions:

If an assembly turns a collection of parts and components into what is recognizably a fau­cet where before the assembly there was no recognizable fau­cet, then the assembly is considered transformative.

Mere attachment of additional components to an already recognizable fau­cet is not "transformation". The fau­cet was already a fau­cet before the components were attached.

The company is not, therefore, an . However, it does design some of its faucets and, with respect to these faucets it is a . Otherwise, it is a , selling faucets designed and manufactured by its suppliers.

For more information on the various fau­cet company business models, see Faucet Basics, Part 7: Faucet Companies, Some Good, Some Not.

Isenberg's Suppliers

Isenberg has chosen its primary suppliers well. All of its manufacturers are companies. These include the following.

The 196.2000 two-handle widespread lavatory fau­cet from Serie 196, shown here in brushed nickel, was designed by Isen­berg.

Isenberg's Designs

Most of the fau­cets sold by Isen­berg are stock fau­cets taken from its supplier's . The designs are owned by the supplier.

However, Isen­berg has designed in-house or through contracted designers a dozen or so of its fau­cets – a list that keeps growing year by year.

These fau­cet designs are owned by Isen­berg. Some are patented. Among these are

The IF.2300 Infinity wall-mounted fau­cet, designed by Anmol Sarin, has been widely recognized for its innovative design.

It won a Good Design Award in 2020 in the Bath and Ac­ces­sor­ies category.

Good Design, sponsored since 1950 by the Chi­cago Athen­ae­um Mus­e­um of Arch­i­tec­ture and De­sign: is the oldest and most prestigious of the product design awards.

Other honors awarded this fau­cet design include a listing by Bet­ter Homes & Gard­ens as one of the 30 most innovative products of 2020 and a design award by Hos­pi­tal­ity De­sign magazine in the Bath ca­te­go­ry.

Mr. Sarin is also credited with the design of the Tanz kitchen fau­cet.

Casio Kitchen Faucet

A split stainless/crimson finish on an Isen­berg Caso K.1200 kitchen fau­cet.

This faucet, manufactured for Isen­berg by Nokite is sold around the world by a number of fau­cet companies.

In Australia, for example, it is the Swedia Signatur mixer tap sold by the Vangard Design Group.

Isenberg's Exclusive Faucets

Some faucets are exclusive to Isen­berg in North America not because it designed the fau­cets and owns the designs but because it has contracted for a protected territory.

The way this usually works is that an importer guarantees to buy a minimum number of a particular fau­cet model. The manufacturer, in turn, guarantees the importer an exclusive right to sell the fau­cet in the U.S. and Canada.

Isenberg's Serie 260 lavatory fau­cets are an example.

These faucets were designed by Jochen Schmiddem of Schmiddem Design in Berlin for Steinberg, GmbH, a German fau­cet company.

Steinberg identifies itself as a Ger­man manufacturer, and that may be true for some of its fau­cets. But, the fau­cets it licenses to Isen­berg are not manufactured in Ger­many. They are made by Catly San­i­tary Wares in China under an agreement between the two companies dating from 2006.

Steinberg sells the fau­cets throughout Europe, South and Central America, the Middle East, and parts of Asia as the Series 230.

Isenberg has acquired the exclusive right to sell these interesting fau­cets in North America.

Isenberg's Collections

Isenberg's bathroom sink fau­cets are, in most instances, a part of larger collections of complementing fixtures and accessories that include showers, tub fillers, towel racks, toilet paper holders, robe hooks, and so on.

Of the three major style groups: traditional, transitional, and contemporary, virtually all Isen­berg fau­cets are contemporary: stark and minimalist with clean lines and no applied ornamentation other than the fau­cet finish.

One series, the Serie 240 is identified by Isen­berg as transitional in styling but even the fau­cets in this series are more contemporary than transitional.

We can find no fau­cet in the Isen­berg catalog that features traditional styling.

If you are looking for a fau­cet to finish off a bath or kitchen in a heritage or traditional decor, you may have to look elsewhere for a fau­cet that is suitable for any period other than the modern era.

Faucet Materials

Isenberg specifies top-line materials for its fau­cets including lead-free brass and stainless steel.

Brass

The brass used in its all-brass fau­cets is lead-free where it comes in contact with water, as required by law.

Lead is very toxic, but before 2014, a fau­cet could contain as much as 8% lead and still call itself lead-free. Now the maximum lead content of those parts of a fau­cet that touch water is 0.25% (1/4 of 1%), basically just a bare trace. In fact, there may be more lead in the air you breathe than there is in a modern fau­cet.

Lead in brass is used to reduce the brittleness of the material making it more malleable and easier to form. To comply with the new restrictions on lead, today's fau­cet brass uses other additives. The most common are bismuth and silicon to reduce brittleness without adding toxicity.

Bismuth is similar to lead – right next to lead on the periodic table of elements – but it is not harmful to humans. It is, however, very expensive. It is 300 times rarer than lead, even rarer than silver, which is the reason that bismuth-brass alloys are considerably more expensive than leaded brass.

Zinc

This increased cost has encouraged many fau­cet manufacturers to use substitute materials in their fau­cets where possible. The most common are zinc or a zinc-aluminum alloy commonly called pot metal.

Zinc, however, is not as strong as brass and does not resist water pressure as well as brass. Its use in the non-pressurized parts of a fau­cet – handles, base plates, etc. – does not harm the quality of a fau­cet, however, and may save a few dollars.

According to Isen­berg, it has chosen not to use zinc. It uses brass for its ancillary fau­cet parts. This does not mean that every part of its brass fau­cets is lead-free. Common leaded "alpha" brass, is often used by fau­cet manufacturers in the parts of a fau­cet that do not contact water. Leaded brass in these parts is perfectly acceptable, posing no health hazard.

Plastic

The company has also chosen to avoid plastic – a very wise choice indeed. Kitchen fau­cets pray heads (the industry term is "wands") made primarily of plastic are standard for many manufacturers, including those that sell upscale fau­cets such as

The Zest pull-down kitchen fau­cet finished in Blue Plat­i­num, one of Isen­berg's Thin Film Ceramic special finishes.

Manufacturers typically give three reasons for their choice of plastic in this component:

Unfortunately, however, plastic fails much more often than metal wands. And although engineers have made significant improvements to their reliability over the past decade, the problem has not been entirely cured.

The Sure Cure for Too-Hot Spray Wands: The simple cure for spray wands that get too hot is to reduce the temperature of the water. Dishes do not need to be rinsed in scalding hot water.

Better wands are made of metal and Isen­berg's wands are the same stainless steel as its kitchen fau­cets.

Stainless Steel

The Klassiker collection of kitchen fau­cets is made from stainless steel.[1] Steel is much harder than brass. It can be made in thinner profiles that use less material and still have more than adequate strength.

Its real advantage, however, is economic. It is less expensive than lead-free brass and it does not need an applied finish. The material itself, buffed and polished, becomes the finish. However, while an applied finish is not necessary, it can be done.

Isenberg does so. Its Klassiker kitchen fau­cet collection can be ordered in any of its 20 special color finishes, including in which the native stainless steel of a fau­cet is accented by one of Isen­berg's color finishes.

Dezincification

Of Isenberg's suppliers, Lo­ta In­ter­na­tion­al is the only company known to use a patented alloy of lead-free brass that resists dezincivication.

Brass is basically an alloy of copper and zinc.

Dezincification is a chemical process that occurs when brass is in near-constant contact with water. The water slowly dissolves the zinc over time. The result is a brass that is porous and brittle with very little strength.

Tin is added to brass alloy used in some Lota fau­cets to protect the zinc and retard the dezincafication of its brass.

Why Stainless Steel Does Not Rust: Properly alloyed stainless contains at least 10% chromium (chrome) and a dollop of nickel. These form a coating of oxides and hydroxides on the outer surface of the steel that blocks oxygen and water from reaching the underlying metal, preventing rust from forming. The coating is very thin, only a few atoms thick, so thin that it is invisible to the eye under ordinary light. It takes laboratory instruments to detect it.

The stainless steel used in Isen­berg kitchen fau­cets is 304 stainless, an alloy that includes chrom­ium and nickel. The nickel gives the steel a crystalline structure which increases its strength. The chromium helps the steel resist corrosion. Stainless 304, also known as "food-grade" stainless, is by far the most common alloy used to make kitchen utensils, silverware, and fau­cets.

Faucet Components

Isenberg uses top-quality components in its fau­cets, the most critical of which are its valve cartridges and aerators.

Valve Cartridges

Isenberg's single-handle fau­cets are fitted with ceramic cartridges made by the European technical ceramics company, Kerox Kft of Hungary.

Kerox is the mixing cartridge preferred by up-scale fau­cet manufacturers. Its reputation is well-earned for extremely reliable cartridges that perform well even in relatively hard water. We know it to be a very good, long-lasting cartridge.

The cartridges used in Isen­berg's two-handle fau­cets are by the German firm, Flühs Drehtechnik, GmbH, generally thought of as the manufacturer of the world's best single-function stem cartridge for two-handle fau­cets.

isenberg's Older Cartridges

Until a few years ago, Isen­berg single handle fau­cets were designed around a cartridge made by Sedal S.L.U.. a technical ceramics company chartered in Spain but manufacturing in China.

Sedal Cartridge

These have been largely replaced by Ke­rox cartridges, but not entirely.

The Isen­berg web­site indicates that some of its fau­cets still use the Sedal cartridge,[2] but, unfortunately, does not identfy the fau­cets so equipped.

Sedal makes a good cartridge, nearly the quality and reliability of Kerox products, but "nearly" is not the same as "equal to."

Earlier two-handle fau­cets were fitted with Tuopu cartridges manufactured by by Hent Tech­nol­ogy Comp­any, an technical ceramics manufacturer located in China.

Hent makes a reliable cartridge but not to the exceptionsl precision of Flühs cartridges. We believe that all of Isen­berg's two-handle fau­cets now include Flühs cartridges and the Hent cartridge is no longer used. But, we have not examined every two-handle fau­cet and cannot be 100% certain.

Before purchasing an Isen­berg fau­cet, you may want to check with customer service to confirm the source of the cartridge used in the fau­cet.


For more detailed information about fau­cet cartridges and valves, their history, and uses, see Faucet Basics, Part 2: Faucet Valves and Cartridges.

The major differences between Flühs (sometimes spelled Fluehs for English speakers) and most of its competitors are

Rather than being cast, they start out as a solid block of lead-free brass that is then machined, step by step, into a cartridge.

Casting sometimes leaves voids and weak spots in the brass, faults that are avoided by mono-block production.

Flühs stem cartridges have established a reputation for leak-free reliability over the past 70 years.

Aerators

Most Isen­berg aerators are made by Neoperl®, considered some of the world's best.

Faucet aerators used to be simple devices that merely added a little air to soften the water stream so it would not splash out of the sink.

Today, however, they are also used to limit water volume to the lower flows required by federal and state water conservation laws, and in some cases, to prevent back-flow that can result in the contamination of household drinking water.

It is important, therefore, that this little device, often smaller than a dime, be the best available. And that, almost by definition, is the Swiss-engineered Neoperl® aerator.

Faucet Finishes

Isenberg does not own a finishing facility and does not finish its fau­cets. It buys them already finished in several standard finishes that vary by manufacturer. If a special color finish is ordered, it is applied in a local facility.

Nearly every Isen­berg bath fau­cet is available in chrome and brushed nickel. Kitchen fau­cets are made of stainless steel and their "finish" is the steel material itself, buffed and polished.

What other standard finishes may be available on a fau­cet depends on its manufacturer. Faucets made by Catly, for example, are also available in polished nickel and satin brass. Some bath fau­cets can be ordered in matte black. Standard finishes are what Isen­berg calls "fast-ship" finishes. They are available in stock for immediate delivery.

Chrome is an finish. The other fast-ship finishes, except Matte Black, are (PVD) coatings.

Electroplating

Electroplating is the well-established traditional way of finishing fau­cets that has been around nearly since fau­cets were invented.

It involves immersing the fau­cet and the metal to be used as plating in an acid bath, then applying an electrical charge to both objects so metallic ions are drawn from the plating metal to the fau­cet. Usually, at least three coats are applied, an undercoat of nickel and then two coats of chrome. The final finish is polished to give the chrome its shine.

The process is potentially hazardous to the operator and the environment. It involves toxic and corrosive chemicals that must be disposed of safely. No other coating technology even comes close to the dangers involved in electroplating.

Physical Vapor Deposition (PVD)

PVD is the latest space-age fau­cet finishing technology, rapidly replacing electroplating as the finish of choice. Although the technology was discovered in the 19th century, it was not used in industry until the 1950s and then only rarely due to its great expense. Its first use was in nuclear reactors. Today, the technology is everywhere and the machinery required is getting smaller, faster, and cheaper all the time.

The process involves loading a vacuum chamber with unfinished fau­cet components. All of the air is replaced with a carefully calculated mix of nitrogen or argon and reactive gases. A rod of the metal to be used for the coating is heated to a temperature so high that the metal dissolves into individual atoms. These atoms mix with the various reactive gases to get the desired color and finish effects and are then deposited in a very thin layer – 2 to 5 microns – on the fau­cet components.

A micron is one millionth of a meter or 1/26,000 of an inch. The average human hair is 83 microns thick. The smallest the human eye with excellent vision can see without magnification is about 5 microns.

Despite being just microns thick, a PVD coating is extremely dense and, in consequence, very durable. By some estimates, it is up to 20 times more scratch-resistant than electroplated chrome. From long experience, we know that PVD is nearly impossible to accidentally scratch or mar, never fades or changes color, and resists all forms of soiling.

Split Finishes

In addition to Isen­berg's standard finishes, fau­cets are also available in 20 colorful special finishes. Some fau­cets, including those in the Klassiker collection of twelve kitchen fau­cets, can be finished in . Part of the fau­cet is left as stainless, the rest is colored.

Special finishes take longer, sometimes a lot longer to deliver than fast-ship finishes since the fau­cets are not in stock and are given their special finish only as ordered.

Thin Film Ceramic (TFC) Finishes

Most fau­cet companies produce their non-metallic color finishes using a process called (See: e.g. ). A powder coat is essentially a powdered paint. It is durable but not as durable as metallic finishes.

Isenberg's color finishes, by contrast, are produced using a new technology called a Thin-Film Ceramic or TFC coating.

TFC, like PVD, is a space-age coating that does not, however, require the elaborate and expensive machinery needed for PVD application. All it requires is a spray gun and a low-temperature oven to cure the finish after spraying.

A powder coat is essentially a powdered paint. It is durable but not as durable as metallic finishes.

TFC [3] is considered a "high-performance" coating that was first used to protect firearms and military field equipment – items that are expected to see very hard use.

The Isenberg Professio F (K.2030) kitchen fau­cet (left) is made by Nokite.

The same fau­cet is sold by the Whitehaus Collection as the WHS1644-SK (right).

The Isenberg fau­cet is priced about 10% less in stainless steel.

Isenberg is one of the very first companies to use it as a fau­cet finish.

A TFC coating usually contains a mix of nano-particles of silicon dioxide and titanium dioxide. These ceramic particles give the finish its robustness, resulting in a very robust coating that resists damage. In standardized laboratory wear tests, TFC coatings were found to be ten times more resistant to wear than steel. The finish is also impervious to virtually all chemical cleaning solutions, resists fading from exposure to ultraviolet rays, and is anti-microbial in some formulations.

The Isenberg warranty guarantees TFC finishes for a lifetime against manufacturing defects, a warranty that shows considerable confidence in the durability of its ceramic finishes.

Keep in mind, however, that no warranty protects against all of the hazards that can befall a fau­cet finish, and Isen­berg's warranty is no exception.

it protects against just those defects that result from errors in the finishing process: peeling, flaking, blistering, scaling, excessive discoloration, and delamination. These are extremely rare, and by "extremely rate" we mean "almost unheard of."

Most damage to fau­cet finishes results from over-zealous cleaning. Modern finishes do not require scrubbing. They need little more than a wipe-down with a mild detergent and a soft cloth. Harsh chemical cleansers or scouring pads are not needed. Finish damage caused by users is never covered by a fau­cet warranty.

Where to Buy

Isenberg sells its products through authorized dealers. A Where to Buy feature on its website identifies the showroom(s) nearest you. The fau­cets are also sold over the internet on sites such as Plumbing Overstock, FaucetLine, Houzz, and even on Amazon (although the selections may be severely limited).

If your choice is a fau­cet in a standard fast-ship finish, an internet purchase is an option. However, if you need a special finish or a coordinated set of fau­cets, other fixtures (tub fillers, showers, etc.), and accessories, then a showroom is probably a better choice. Showrooms are plentiful on the East and West coasts; less numerous in the middle of the continent.

Minimum Advertised Pricing

No matter where you buy, do not expect deep discounts on Isen­berg products.

The company enforces a Minimum Advertised Price (MAP) policy that prevents dealers from advertising a discount greater than allowed by the policy. Violators are at risk of losing their dealership.

Its purpose is to discourage deep internet discounts that would undermine brick-and-mortar showroom pricing.

We are not privy to Isen­berg's actual MAP policy, a document available only to dealers, but we were able to calculate the maximum allowable discount from Isen­berg's list price as about 33%.

Isenberg Faucet Warranty

The company backs its fau­cets with a lifetime warranty that meets the minimum requirements of the standard North American fau­cet warranty.

It provides adequate protection against defects in the material or manufacturing pro­cess that produced the fau­cet

"to the original consumer purchaser for as long as the original consumer purchaser owns their [sic] home."

The warranty does not appear to have been drafted by a lawyer. It has many defects, some major and some minor.

The most problematic are its multiple violations of the Mag­nu­son-Moss War­ranty Act (15 U.S.C. §2308), the federal law that governs the form and content of consumer product warranties in the U.S.

Apart from its prohibited provisions, other problems with the warranty lie in some of its language that may produce results not intended by Isen­berg, a common defect in "cut and paste" warranties not drafted by a lawyer.

An example is the warranty's definition of lifetime: "for as long as the original consumer purchaser owns their [sic] home". It has two defects:

Here is an example:

Buyer installs an Isen­berg fau­cet in his house. A few years later he replaces the fau­cet with a newer Isen­berg fau­cet and gives the old fau­cet to daughter Nell who installs it in her house.

The warranty on the old fau­cet is still in force because Buyer still owns "their home."

The question is: if the old fau­cet starts to leak, can Buyer claim under the warranty for the benefit of daughter Nell?

And, the answer is "yes." The warranty is a contract, and in most states, a party to a contract can enforce the contract for the benefit of a person who is not a party to the contract.

Isenberg may argue that the warranty expired when the Buyer gave the fau­cet away, but it will have to point to the language in the warranty that says that, and there is no such language.

It may be that Isen­berg intends to exclude non-home­own­ing customers and allow the benefits of the warranty to extend to every subsequent owner of an Isen­berg fau­cet, but probably not. These are just two of several examples of the unexpected consequences of the inexpert draftsmanship of the Isen­berg warranty.

The Isen­berg warranty urgently needs the attention of an experienced warranty lawyer to eliminate the illegalities and clean up its language.

However, its many flaws generally benefit the consumer, creating rights that Isen­berg probably did not intend to provide. They do not detract from the level of consumer protection afforded by the warranty. While the warranty may cost the company, they are not likely to cost the consumer, so we can find no reason to deduct points from Isen­berg's warranty score.

For an example of a lifetime limited warranty that meets all of the requirements of Magnuson-Moss, see our Model Limited Lifetime Residential Warranty.

Isenberg Customer Service

Isenberg's customer service is responsive and effective. Formerly, however, getting in contact with a customer service agent could be vexing.

A telephone call to the company's toll-free number was greeted by one of the longest voicemail messages we have ever encountered – extolling the company's 20 color finishes and Cascade tub filler – repeated twice before allowing the caller to leave a voice message to be answered "within 24 hours."

This, thankfully, has all gone away. A call to customer support is now answered almost immediately by a person, eliminating all electronic answering. Robotic answering machines are one of the most annoying features of our electronic age, and for doing away with its electronic answering alone, Isen­berg gets a gold star.

Problems get resolved quickly and courteously without much fuss. We did not conduct our usual formal customer service tests. For small companies like Isen­berg, they do not work well. Agents quickly figure out they are being tested. But, the results of our informal contacts were more than satisfactory.

The Better Business Bureau rates Isen­berg's handling of consumer issues an A+, the highest rating on its scale of A+ to F. However, the company has not been vetted and accredited by the BBB and is not pledged to its high standards of business ethics. It should become accredited.

Isenberg Website

The company's website is very well structured and easy to use with intuitive navigation.

Most of what you need to know about an Isen­berg fau­cet, including its certifications and whether it is Watersense® or ADA qualified appears in the fau­cet's specification data or parts list all in English, and all well laid-out for easy comprehension.

Products are easy to find using filters arranged along the left edge of the web page. These allow the selection of fau­cets by location (kitchen or bath), collection (or Serie), finish, configuration (centerset, widespread, wall-mounted, etc.), number of handles, compliance with the Americans With Disabilities Act or Watersense®, flow rate, and handle type (knob or lever).

We found a few weaknesses, however.

For many fau­cets, the cartridge used in the fau­cet is identified by name, not in the specifications where we would expect to find it, but under a tab labeled "Additional Information."

This is not true of every fau­cet, however. About half of the fau­cets listed on the Isen­berg website do not show cartridge information, but most display the cartridge part number under the heading "Common Spare Parts.". Using our Faucet Cartridge Table, you can find the cartridge from the part number.

Another issue we found was a failure to link the fau­cet warranty to each page on which a fau­cet is listed. The warranty is referenced with the notation: "Limited Lifetime Warranty. See Warranty page for complete details", but there is no actual link to the warranty page.

A "conspicuous link" to the warranty is required by the Mag­nu­son-Moss pre-sale availability rule. A warranty must be available to be read before the sale of a consumer product.

To find the warranty, the user has to go all the way to the bottom of the page and look under SERVICE AND SUPPORT for "warranty."

The site search function is robust. It easily handled searches for products. It found any series (as long as you remember that the correct term is "Serie" and not "Series"). It also produced good results when searching on a standard finish – useful in identifying all of the products available in a specified finish.

On non-product searches, it did not do as well. For example, it did not find the Isen­berg warranty when asked to search for "warranty".

Other features of the website that we like are found at the bottom of each page. These include:

Some of the links are interesting. One we particularly enjoyed is the Color Your Kitchen link that displays extensive information on using Isen­berg's large selection of color finishes to add a little pizzazz to your kitchen.

Testing & Certification

Isen­berg has always been meticulous about ensuring that its fau­cets are certified compliant with all of the laws and regulations that govern the sale and installation of fau­cets in a drinking water system in the U.S. and Canada. In the several times we have checked on its certifications, we have yet to find an Isen­berg fau­cet offered for sale that was not fully tested and certified.

CalGreen Logo CalGreen® Certified: At least some but not necessarily all Isen­berg fau­cets comply with the energy-saving requirements of the California Green Buliding Standards Code. For a fau­cet to display the CalGreen label, it must have been tested for compliance with CALGreen Chapter 4, Residential Mandatory Measures, Section 4.303 Indoor Water Use and certified by an independent testing organization.

Conclusions

Our bottom line on Isen­berg fau­cets is that they are a good choice for those looking for an upscale fau­cet without the upscale price.

Some of Isen­berg's fau­cets are its own designs – very clean and elegant. Most, however, are well-chosen off-the-shelf fau­cets with good to excellent styling. While only a few of its fau­cets will please the design glitterati among us, for most of us "just folks", Isen­berg's designs are just fine.

But, the best feature of the fau­cet line is that for what you get the fau­cets are cheaper – sometimes substantially cheaper – than most of its competition (see the list above). You can buy a good quality Isen­berg lavatory fau­cet for under $200, a price point that even mid-priced fau­cets from struggle to reach.

Isenberg's thin-film ceramic special finishes are a long overdue and welcome innovation in the fau­cet industry. This very durable finish has been around for a number of years and we were waiting for someone to start using it on fau­cets. That day has come. However, be aware that selecting a special finish can substantially increase the cost of the fau­cet.

In sum, Isen­berg fau­cets are well made by some very respected manufacturers and include good compoents. The finishes are varied and interesting. The company's Thin Film Ceramic finishes are a good choice for a non-metallic finish.

For the price, most Isenberg fau­cets are a very good to excellent value and well worth consideration by those looking for a stylish, well-made fau­cet supported by a strong warranty and excellent customer service.

We are continuing to research the company. If you have experience with Isen­berg fau­cets, good, bad, or indifferent, we would like to hear about it, so please contact us or post a comment below.
