The quality of the Kohler brand can directly create an expensive perception in users’ minds. However, as with every product, Kohler offers a solution for users looking for a toilet suitable for their budget with the Wellworth Toilet model. Let’s examine this model, which is in fourth place on our list.

For users who often have half baths or who divide the majority of the space into the shower section, it may cause the obligation to buy a hanging toilet. In this sense, the Kohler Wellworth Toilet offers users the opportunity to save space without hanging the toilet. Especially for families who give toilet training to their children, it can be difficult to keep water savings. Fortunately, Wellworth Toilet helps you get ahead by reducing water usage by more than 30 percent compared to the high-efficiency 1.1 gallons per wash, 1.6 GPF mode.

One of the features we like about this model is its design. Because Wellworth Toilet has a transparent round front bowl made of glassy porcelain, this two-piece model also comes with an innovative two-tone sidearm. In other toilets, the flush arm is almost in the same place in this model. In this way, you can put your accessories or toilet paper in the upper area.

If you use canister valves in your toilets and baths, your valve will drip water from all sides of the bowl, and this 360 type of water pressure increases the effectiveness of washing.

Kohler 3810-0 Santa Rosa Toilet

While a toilet is preferred, being easy to clean is also an important criterion. While you need to make an effort to maintain hygiene in two-piece toilets, it is much more comfortable in one-piece toilets. That’s why if you are looking for a Kohler one-piece toilet, we have examined Santa Rosa Toilet, which is in fifth place on our list.

Santa Rosa uses just 1.28 gallons of water per flush. It fills the tank quickly with the AquaPiston system. You don’t have to spend too much time cleaning after you’re done, this model is designed in Kohler’s Comfort Height style. It means it’s 2 inches from the ground. The long bowl helps men and women to use it cleanly. You may like this aspect because the most significant difficulty for women to use the toilet after men is the stains on the seat. Besides, it comes with a seat, unlike other models.

Despite this, Santa Rosa Toilet still secures the trust of its users with a one-year warranty option.

system, you can get help from a plumber in repairing the pipes there. In cases where you do not find the user manual sufficient, you can set up your toilet with support from the videos.

Large tank toilets can be a good option in terms of more water tanks and using the upper part as storage. However, not every user can have this vast area. Therefore, narrow tanks will be a better choice for these users. Here we have examined Tresham Toilet, which is in the sixth place on our list, for you, those who have small spaces and are looking for a Kohler toilet.

Kohler Tresham Toilet is a toilet bowl in a wide variety of different designs. In this model, which has almost similar features with traditional toilets, everything except the bowl is square or rectangular. You can see indentations even when you look at the front of the tank.
