KOHLER Wellworth Toilet Review


The Kohler wellworth toilet has an elongated, standard height of the toilet bowl. It measures 3”x18”x28.75”. The two-piece toilet comes with a tank cover lock. It weighs about 3.2 ounces and is made of China.

One of the most distinctive features, perhaps, of the toilet is its easy installation. It has a 3-bolt installation that saves a tremendous amount of installation time. Its elongated and huge capacity design allows 1.6 gallons per flush.

In addition to these features, it has a gravity-based flush. This ensures that the flush strength is huge and powerful, cleaning better.

A hand lever is placed at the left side of the toilet.


Perhaps the appearance of the KOHLER wellworth toilet is the best part. It has a sleek, elegant and sophisticated design. Therefore, this toilet is the perfect one to install in your home and complete the look.

It has an all-white finish and built with china. The elongated design of the toilet gives it a very shiny touch. It has a shiny silver handle at the left side that remains prominent and adds to the elegance of the toilet.

Moreover, it is not a traditional toilet. The water tank behind the seat has a lot of room on the top. You can conveniently utilize this space to store shampoo bottles and other items in the bathroom.

In addition to its sleek and unique design, it also has a comparatively large base that ensures balance. This overall enhances user experience with comfort and full support.


The Kohler wellworth toilet seals the deal with its 1-year warranty. The 1-year warranty is however limited and begins right after the date of installation.

Compared To Other Products

To help you get a thorough understanding of the products in the markets, here is a comparison between two competitive products.

The TOTO CST744SG#01 Drake 2-Piece Toilet is again from a well-known manufacturer. The toilet by TOTO is, however, less competitive when it comes to comfort. The product is much harder to install, has no bowl cover, and has narrow pes that makes cleaning difficult. Otherwise, its functions like gravitational flush system are just as same as the KOHLER toilet.

Furthermore, the TOTO toilet is of a glass-like material, in comparison to the better built KOHLER china toilet. However, as a result of different material, the TOTO toilet weighs less. The glass-like material also ensures a long-lasting finish.

The TOTO toilet also comes in a variety of colors. Meanwhile, the KOHLER toilet has similar color variants.

If you’re looking for a toilet for use for people with joint pains, then the TOTO toilet may be the one. However, for a more durable, stylish yet eco-friendly option, the KOHLER toilet wins.
