The Kohler K-158-4-PB is a great kitchen faucet for buyers that are into the antique look. Price-wise, it is on the high end, even compared to other top-tier Kohler products. If this is the style of faucet that you’re into, it will fit well in any home with an old-school aesthetic. The great thing about this Kohler model is that it really doesn’t have any rivals. Antique models seem to stand out on looks and quality, and it is that uniqueness that makes one a great buy. Even after combing through Kohler’s lineup for worthy rivals, the K-158-4-PB is still a one-of-a-kind kitchen faucet. However, K-158-3-BN is also be considered by the customers of Kohler because of the similar design. The brand is one of the more popular in the industry and is known for being the first to introduce new features and looks. Kohler is the definition of quality, so you’ll definitely get your money’s worth with this model.

Key Features

Kohler antique kitchen faucets have a lot of key features worth pointing out. Many of these features make the hefty price worthwhile, while others are ‘nice to haves’ for any kitchen. In particular, the K-158-4-PB is known for:

Three High Quality Colors

The available colors are vibrant polished brass, vibrant brushed nickel, and polished chrome. All colors fit the antique look well, and really make this one of the best-looking antique designs in the industry. Brass is the best choice for this model, but the other two colors are just as aesthetically pleasing. The selection of three colors is not as limiting as it seems since each color brings something a little different to the table. You can even set this model in a modern kitchen and it will fall right into place without being an eyesore.

Good Spout Reach

One thing that isn’t highlighted enough about this faucet is the spout reach, which comes in at a generous 85/8 inches. This is an ideal size for small or large kitchen sinks and works as an advantage in either scenario. The spout height is another bonus; at 61/2 inches it’s not too high and not too low. When measuring for bigger kitchens, this affects the usefulness of the product. The versatile spout reach is one reason why this particular Kohler model is so popular.

Low Flow Rate

With only a 1.5 GPM flow rate, this faucet can save you a lot of money. The faucet strikes the perfect balance between using less water while still being powerful enough for hard-to-clean dishes. It’s one of the best implementations of a low flow faucet type. You can count on this faucet to pay for itself with the money you’ll save on water bills over its lifetime.

Durable Valve Type

This Kohler product uses the reliable ceramic disc valve. Even with heavy use, this style is known to degrade much slower than others. Coupled with a low flow rate, this gives the product a very long lifespan in any home. Disc valves are the latest innovation in kitchen faucets and remain one of the best selling types. You can count on this model to live up to the hype.

Sturdy Brass Construction

The second to last key feature has to do with the overall construction of the faucet. Brass is one of the best materials you can use for water-based products, especially top-end Kohler faucets. It is resistant to nicks and normal wear, so fairs well in large family households. The three available colors pair well with the brass material, whether it be the chrome, nickel or brass version. This is the best quality you can get in an antique faucet from a top brand name. The one-of-a-kind construction definitely justifies the price.

An Escutcheon That Is Worth Including

More often than not, the escutcheon that comes with the kitchen faucet doesn’t match the quality of the faucet being sold, so you get a cheap cover paired with an expensive faucet. That isn’t the case with this Kohler model, which comes with a top-three escutcheon that matches the quality of the antique faucet. You have to see it to believe it, as it is one of the better ones available from the brand.

Frequently Asked Questions

Does The Side Sprayer Have The Same 1.5 GPM Limit?

The side sprayer retains the same water saving standards as the rest of the kitchen faucet. Even when operating with the power option, the side sprayer maintains a max GPM of 1.5. Lengthening or shortening the hose for the side sprayer won’t affect the GPM, so it is safe to add on your own modifications. Just don’t go overboard with the length and the 1.5 GPM should carry over to the side sprayer just fine. In a worst-case scenario, the water pressure might dip below 1.5 GPM for hoses that are too long in length.

Do All Three Colors Have The Same Durability?

On the surface this seems like a silly question, but with a Kohler product it makes sense. Some models’ resistance is tied to the particular style and color. For example, black kitchen faucet paint will wear over time while a chrome finish will retain its high shine. It’s different for each model, but in the case of the K-158-4-PB, it isn’t an issue. All of the available colors will retain their look without any noticeable wear. By the time you notice any degradation in color quality, it’ll already be time to replace the entire faucet.

Are The Finishes Resistant To Chipping?

Yes, just as the colors are protected against normal degradation, they are also highly chip-resistant. Add this to the other features like water, dent and rust resistance. One thing to note is that while the finishes are strong against dents and scratches, internal parts wear out at a normal rate. So while the outside of the faucet may look brand new, it is important to check that it is internally operating at peak efficiency. This isn’t necessary on a regular basis, and owners can get by with yearly checkups unless a problem becomes noticeable.

How Difficult Is The Installation?

Kohler products are easy to handle, even the antique models. Installation is a breeze for both first timers and experienced users. The provided instructions are clear and easy to follow and provide pictures to follow. These same instructions are available online if you want to skim them on a tablet, phone, or computer — that includes the specification sheet and parts diagram. With all of this information at your fingertips, the installation should take less than a half hour total, including cleanup. Don’t forget to measure the escutcheon and account for the extra space it will take up once installed. It shouldn’t be a problem, but it is always a good idea to be prepared.

What Type Of Warranty Is Provided With The Product?

Buyers will get a limited lifetime warranty, standard for most of Kohler’s high-end products. This should cover some of the most common problems found with kitchen faucets after heavy use. The K-158-4-PB has had no reported out-of-the-box mechanical issues. It is a kitchen faucet that barely needs the protection of the warranty attached to it.

What Does The Customer Say?

Excellent Product For The Price

The price is high, but most consumers won’t fixate on it for too long. In fact, with all of the included features and high quality, the praise for this product is that it’s worth the money. Everyone considers this a bargain, even at its high price. This goes to show that price ranges are irrelevant when the product exceeds expectations. For antique designs, that is a big deal since it has more to do with the looks than the actual function of the product. Competing antique faucets at this price will have a hard time matching up to Kohler.

Fantastic Design For Any Kitchen

Antique looks don’t always mesh well with specific kitchen designs. Kohler gets around that (somewhat) with its highly compatible shape. Combine that with good color choices and you have an antique faucet design that is slightly more adaptable than competing models. There are still areas where the design doesn’t work, but that has more to do with the antique look rather than bad design practices. For what it’s worth, Kohler pulled off the impossible and managed to please a lot of their customer base without limiting their installation options.

The Hose Length Is Just Right

There was an overwhelming response to the length of the side spray hose. Sometimes it is too short and forces the consumer to modify it or rearrange their kitchen to fit the short length. This particular Kohler model is just the right length for kitchens of all sizes. Consumers that want to modify the length will be met with favorable results, as it is very user friendly to swap out. A lot of the reviewers mentioned that the hose length was longer than they expected. When it comes to side sprayers, you can never have a hose length that is too long.

The Best Antique Kitchen Faucet From Kohler

Consumers have a nice selection of antique kitchen faucets in the Kohler catalogue. There is still room for more, but this model has become their very best. At least from a customer standpoint, it is the most favorable in terms of features, looks, and durability. Out of the many brands that offer antique designs, Kohler was recommended as a top-three brand. The K-158-4-PB model is favored by many consumers and continues to receive high praise for its unique look.

Saves On Water Costs

At 1.5 GPM, customers that are living the green lifestyle will save a lot of money in the long run. There has been much praise for how well the faucet manages water, even when using the side sprayer. This is a big deal if you live in a large home with a large volume of traffic that goes through the kitchen. The savings provided by this Kohler faucet is evident when it is used in large volumes. After a few months of heavy usage, it will shine as one of the best purchases in the home.

Final Words

It’s hard to argue with the fact that this is one of the best antique faucets in the world, and the best Kohler antique faucet on the market. It is beautiful to look at, holds up well to a lot of the break-in tests, and is easy to install. This Kohler faucet is everything you want from a high-end product in a home that has high standards. Buyers that are looking for a cheaper alternative can get a somewhat similar experience with Kingston or Lordear branded antique faucets. There is a serious off in quality and design, but it serves as a good choice if the Kohler brand is out of your price range.

For a different antique faucet on the same quality level, the Waterstone 5100-AP has been described as a direct competitor to the K-158-4-PB. It is high-priced, beautiful, and has that same unique antique look that made the Kohler faucet so popular. When you put these choices side by side, it’s difficult to decide on one.

The Kohler K-158-4-PB isn’t for everyone, and will not find its way into most homes. But it is a very distinct model with a lot of great support from the Kohler community. In the right home, this antique kitchen faucet is the perfect way to complete a kitchen.
