Is Kohler Wellworth a Good Toilet?

Kohler Wellworth comprises many different models of the same toilet but with different features and specifications. Kohler makes it in the United States, and it is one of their most known model along the Kohler Cimarron and Highline.

The Kohler K-3987-96 Wellworth toilet is a 2-piece round-front dual flush toilet with a 12-inch rough-in and a standard height. It consumes 1.1/1.6 gallons of water per flush and is, therefore, EPA WaterSense certified.

Kohler Wellworth is a good toilet if you are looking for a toilet in the mid-range price region. It has decent flushing power, is water-efficient, and, most importantly, you get a 5-year warranty on the toilet tank parts and a life-long warranty on the vitreous china material.

 Although there are different models of the Kohler Wellworth, the Kohler K-3987-96 Wellworth toilet is the most popular. The other 2 popular Wellworth models are:

  1. Kohler K-3998-0 Wellworth Toilet – Elongated bowl
  2. Kohler K-3948-T-0 Wellworth Toilet – 14-inch rough-in

We will therefore start by looking at the Kohler K-3987-96 Wellworth model and compare it with other toilet brands and other Kohler toilets in the same price range or even higher, like the Kohler Cimarron and Kohler Highline.

Pros and Cons of Kohler K-3987-96 Wellworth Toilet

So, what are the advantages and disadvantages of installing the Kohler K-3987-96 Wellworth among other models or any other toilet in general? Let us start with the benefits.

1. Best for Small Bathrooms

The Kohler Wellworth has a depth of 27.75 inches which is 2 inches or even more, less than most elongated toilets. For people with a small bathroom, every inch counts. This is why the more comfortable elongated toilets have not completely phased out the round-front toilets.

2. Comfortable for Kids

Although elongated toilets are marketed as more comfortable than round toilets, most people don’t bother to get kids’ opinions. Ask any kid, and they will tell you they feel like they are all falling inside the bowl when using an elongated toilet.

Round toilets are about 16.5 inches in length, while elongated toilets are 18.5 inches long. Their widths are almost standard. The extended length of the elongated toilets is too much for kids.

This makes the Kohler Wellworth a good toilet for the children’s bathroom.

3. Standard Height

A standard-height toilet is a great choice for people not tall and children. In order to use a toilet comfortably, both legs need to be solid on the ground.

Using a toilet while your feet are dangling in the air is a health risk and uncomfortable. Check out this post for more on the pros and cons of comfort height vs. standard height toilets.

4. Kohler Wellworth Black Toilet

The Kohler Wellworth is available in white, black, biscuit, and almond, but the black one stands out. Black is so bold, and as they say, you can never go wrong with black. A black toilet looks great, especially when paired with another black fixture, like a bathroom sink against bright bathroom walls. If you would like to see more black toilets check out this post.

5. Dual Flush

Kohler K-3987-96 is a dual-flush toilet. You will have the option to use either 1.1 or 1.6 gallons of water based on the load you need to flush, thanks to its dual-flush functionality. It may not look like much, but Kohler estimates you could save up to 4000 gallons of water in a year.

Different from the dual flush buttons of other toilets, this toilet has 2 levers. There is the green and longer lever for liquids (1.1 GPF) and the chrome lever for solids (1.6 GPF.)

6. Powerful Flush

The Wellworth uses Kohler’s class five flushing technology, designed to flush a toilet powerfully and quickly thanks to its large flush valve. It uses a canister flush valve that allows water to enter the bowl from all sides hence cleaning and rinsing the bowl.

7. The DryLock tank installation system

To install most toilet tanks on the toilet bowl, you would need to put the tank bolts inside the tank and then through 2 holes at the bottom of the tank. The Kohler Wellworth is different.

The toilet tank has no bolt holes, but rather what you do is hook up the bolts from underneath the tank and proceed to install it. This system is fast and also prevents leaks which normally happen between that tank and the bowl.

The Cons

Some of the pros of Kohler Wellworth turn into cons when the end user is changed. Let us look at the disadvantages of owning a Kohler Wellworth toilet.

1. They are not very comfortable for adults

Compared to oval/elongated toilets with more surface area, Kohler K-3987-96 Wellworth toilets are less comfortable for adults. Due to their anatomy, men prefer an elongated toilet way more than round-front ones.

2. They are not ADA-Compliant

The Americans with Disabilities Act (ADA) was enacted to regulate the height of toilet bowls, among other requirements. The specific requirement about toilet bowl heights is that they should be of comfortable height (17-19 inches)

Apart from the ADA requirement, ADA-height toilets are also ideal for tall people, older adults, and people with limited mobility.

3. Do not come with a toilet seat

The Kohler Wellworth is not sold with a toilet seat, and therefore you will need to buy one separately. It does also not come with the wax ring and water supply line, which you will also have to buy separately.

As you can see, the difference between the Kohler K-3998-0 Wellworth and Kohler K-3987-96 Wellworth is the dimensions, water consumption, and the toilet bowl.

While one is manufactured for a smaller bathroom, the other is made for an ordinary bathroom. Another difference between the two is the price. The Kohler K-3998-0 Wellworth is way cheaper than the Kohler K-3987-96 Wellworth.

Kohler K-3948-T-0 Wellworth

Kohler 3948-RA-0 Bath Hardware, White
  • Elongated, standard height toilet bowl
  • 14-in (35.6 cm) rough-in
  • 31-5/8-in (80.3 cm) x 18-1/4-in (46.4 cm) x 28-3/4-in (73 cm)

The Kohler K-3948-T-0 Wellworth toilet is a 2-piece elongated toilet with a 14-inch rough-in. It has 1.28 gallons per flush rating and has a standard height.

The rough-in is the distance between the rear wall of a toilet and the center of the toilet’s drainpipe. If your toilet is already installed, you should measure from the wall to one of the toilet bolts.

Most modern toilets have a rough-in of 12 inches, but in old houses, toilets have a rough-in of 10 or 14 inches. A toilet with a rough-in of 12 inches cannot be replaced with a 14 inch.

A 14-inch rough-in toilet can, however, be replaced with a 12-inch rough-in toilet. A 2-inch gap will, however, be left between the toilet and the wall. The Kohler K-3948-T-0 Wellworth is a 14-inch rough-in toilet that should not be confused with the 12-inch rough-in Kohler K-3987-96 Wellworth toilet.

Kohler Wellworth vs Kohler Cimarron

Kohler Cimarron is a 2-piece comfort height single flush elongated toilet that is one the best black toilet. It has a water consumption of 1.28 gallons per flush.

In terms of appearance, the Kohler Cimarron looks sleeker and more modern than the Wellworth, which appears more standard. The elongated bowl helps to enhance the Cimarron’s appearance.

Both toilets flush quite powerfully, but Kohler Cimarron has a slight edge over the Kohler Wellworth thanks to its AquaPiston canister that ejects water into the bowl at a 360 degrees angle.

Kohler Wellworth vs Kohler Santa Rosa

The Kohler Santa Rosa is a one-piece single, flush compact elongated toilet that uses 1.28 gallons of water per flush.

Compact elongated toilets were designed to take up the space normally occupied by round toilets without compromising the comfort of elongated toilets. If you, therefore, need an elongated toilet but have a small bathroom, you should consider Kohler Santa Rosa.

Kohler Santa Rosa is a beautifully designed and sleeker toilet, way more than the Kohler Wellworth. With all these nice features, Kohler Santa is more expensive than Kohler Wellworth.

Kohler Wellworth vs Toto Drake

The Toto Drake has a depth of 28.125 inches, a width of 19.875 inches, and a height of 30.5 inches. Its toilet bowl height is 16.5 inches from the floor.

The H2 Option has a depth of 29. 75 inches, a width of also 29.75 inches, and a height of 30 inches. It has a bigger width, therefore

Final Words

The Kohler K-3987-96 Wellworth toilet is one of the best mid-range toilets. It is an excellent choice for people with small bathrooms who need to utilize every inch of space available. The dual-flush feature means it is very water efficient and yet flushes powerfully.

Of the five toilets that we have compared the Kohler Wellworth with, Kohler Santa Rosa was the one that gave the Wellworth a run for its money. The Santa Rosa, however, cost way more than the Kohler Wellworth.

If the Kohler Wellworth is currently out of the range for you but wouldn’t mind an elongated toilet, the Toto Drake elongated bowl and tank toilet would be an excellent choice. It flushes well and is considerably cheaper. If you only need a Kohler, the Kohler Wellworth elongated toilet should suffice.

Another great choice would be the American Standard H2 Option, whether elongated or round. For anyone wishing to experiment with a black toilet, Kohler Cimarron wouldn’t be a bad choice at all.

If you need a 10-inch rough-in toilet with about the same specifications as a Kohler K-3987-96 Wellworth, you should consider the Kohler K-3889-T-0 Highline toilet. It has a round bowl and a flushing rate of 1.28 gallons per flush.
