Kohler Caxton Rectangular Sink Reviews 2022: Why has the K-20000 become so popular?

Kohler Caxton Rectangular Sink Reviews 2022 (read our in-depth analysis) (2)The K-20000 features one of Kohler’s most elegant yet simple designs. It is priced reasonably to make it affordable for a more extensive customer base. Like all Kohler products, it comes with some stunning features.

Let’s understand the reasons for this sink becoming so popular:

The Kohler Advantage

Kohler is one of the most reputed brands in the kitchen and bathroom fittings industry. Consumers correlate the Kohler brand with unparalleled quality and top-notch products. So, it will undoubtedly be an excellent and safe decision to install a bathroom sink that comes from one of the market leaders.

We especially liked the fact that it features an efficient overflow drain which ensures no accidental flooding. The rounded bottom ensures no splashing and spilling of water over the edges of the sink. And its mix of rectangular shape and rounded bottom makes it one of the most ergonomically designed bathroom sinks in the market.


Whether your bathroom has a traditional or a modern setup, this sink from Kohler will look perfect in it. It also comes in ten different colors for you to choose from. How can you not like such versatility?

The bowl dimensions are 20.3 inches long, 15.8 inches wide, and 7.3 inches deep. You can install any faucet on this sink without having to worry about water spilling over its edges. The only limitation is that it does not come with faucet holes, so you have to install a counter or wall-mount faucet.

Elegant Style

You will appreciate its smooth surface, which lends a premium look to it. Unless they know it, nobody would guess that this sink costs less than a hundred bucks by the looks of it.

It’s also easy to preserve its elegance. All you need to do is use a dampened sponge or soft cloth to clean it. Just remember to test the cleaning solution on a small area before applying to the entire sink.

And once you’re done, rinse thoroughly with water and wipe it with a soft, dry cloth.


Nobody wants to replace bathroom sinks every couple of years. One of the essential features that separate an extraordinary bathroom sink from mediocre ones is long-lasting performance and durability. The K-20000 is made from vitreous china and features a sturdy design that will last for years.

It comes with a one-year limited warranty and is ADA compliant and CSA certified, which hints at its durability and quality. Although it is reasonably straightforward to install, we recommend that you follow the installation guide to be on the safer side.

Where does the K-20000 Disappoint?

The K-20000 bathroom sink is not a top-notch product and is affordably priced to appeal to a larger customer base, unlike other premium products from Kohler.

It comes with four metal clips for undermount installation, which is easy unless you have a stone countertop.

And in that case, you will have to drill four screw anchoring areas and fill them with appropriate thread-able material to use these clips for installation. It is not a significant shortcoming and should not affect your decision to buy the K-20000 bathroom sink.
