Kohler first launched the Wellworth toilets in 1936. Since then, the toilets have continually set the standard regarding innovation.

The Wellworth K-3987-0, in particular, was first introduced in 2013. The toilet improves on earlier models, like the Kohler Cimarron, by having a graceful design and being both high-efficient and affordable.

To help determine whether this is the toilet you have been looking for, here is a comprehensive review.

Construction and Workmanship

To start, the K-3987-0 is a two-piece toilet. That means it comes as two separate pieces—the toilet tank and the toilet bowl.

The most significant benefit of a two-piece toilet is that it is light and therefore easy to move around. Also, you can take the toilet apart at will.

The toilet has a round-front bowl which means it takes up minimal space. Consequently, if you happen to have a small bathroom, then the K-3987-0 will fit perfectly.

However, that does not mean that you cannot purchase the toilet if you have a large bathroom. It fits in large bathrooms as well.

More About the Look of the Kohler K-3987-0

The toilet is made from vitreous china. As a result, it has a modern look, and it is durable. Note that the K-3987-0 is available in four different colors.

Consequently, you can choose the color that you like best and more importantly a color that complements your bathroom’s décor.

Regarding dimensions, the toilet measures roughly 14.5 inches from the top of the bowl to the floor. That means the toilet has a standard seat and not the comfort height found in some models. With a standard seat, you sit further off the ground.

Finally, please note that the toilet does not come with a toilet seat. Thus, you have to purchase the seat separately. However, that is not an issue because a standard round seat from a local plumbing store will fit.

Also, purchasing the toilet seat as a separate piece means you get to decide on the right style or color depending on your preferences.

Features and Specifications

The Flushing Mechanism

The Kohler K-3987-0 features a trip lever which offers dual-flush options.

The options constitute a flush of either 1.1 gallons or 1.6 gallons.

You can use the partial flush of 1.1 gallons for liquid waste and the full flush of 1.6 gallons for solid waste. That saves on water and helps ensure the toilet is WaterSense certified.

Moreover, because the trip lever allows you to access both flush options; the toilet has only one handle. That is highly convenient as it eliminates the need for buttons or multiple handles.

In addition, the Kohler K-3987-0 also features a class five flushing technology. The technology facilitates bulk-flushing performance thanks to its design.

The Flush & Canister Valves

For one, it has a large canister flush valve. The flush valve allows the rapid release of water to facilitate a powerful clean. Additionally, it combines this powerful release of water with a direct-fed jet. As a result, your bowl is always sparkling since no waste is left behind.

Second, the canister valve ensures water flows into the bowl from all sides. This increases the effectiveness and power of the flush.

Third, the canister design comprises 90% less exposed seal material. The fact that the seal is not exposed means it does not wear off easily. Therefore, you do not need to worry about leaks.

Finally, the universal red seal is of high quality which means it is durable. Also, that it is universal means replacing it when the time comes is effortless.

Choose The Color You Like

As noted above, the toilet comes in four choices or colors. Those colors include; Almond, Black, Biscuit, and White.

Performance of The Kohler K-3987-0 Wellworth Toilet

With regards to performance, the first thing to keep in mind is that thanks to the class five flushing technology, the toilet is not prone to clogging.

Second, even though the toilet is a two-piece, it comes with a wax ring that plays a great role in helping to prevent leaks after mounting the toilet.

Therefore, frequent leaks that require a plumber and cost you a significant amount of money are no longer an issue.

Finally, thanks to the one handle that activates both flushes the toilet is ideal for those who struggle with reading due to reading disabilities. A good example is a dyslexic person who would struggle with figuring out which button is which.

ADA Compliance

If you are looking for a toilet to install in a restroom or for public use, then the toilet must of necessity be ADA compliant.

Therefore, during the purchase, you must keep this in mind. The K-3987-0 is not ADA compliant which means it might not be ideal for a public space.

However, if the toilet is for home use, then whether the toilet is ADA compliant or not will depend completely on your preference.

Standard Toilets Vs. Macerating Toilets

A standard toilet features an S-shaped waste pipe that sends waste down into a waste water-system such as a sewer or cesspit.

For this to happen, the toilets utilize gravity and a suction system.

On the other hand, a macerating toilet first grinds the waste into mush and then sends it down the disposal system.

It is vital to know this because it helps determine where you can place your toilet. With a standard toilet, because of the reliance on gravity, you can only place it above the waste pipe.

However, with a macerating toilet, because it does not depend on gravity, you can either place it level with the waste pipe or below the waste pipe. Depending on where you place the toilet, the aesthetic of your bathroom will change. Note that the K-3987-0 is a standard toilet.
