Whether you are remodeling the downstairs bathroom or putting in a new powder room off of the laundry, you are going to need to shop for a new toilet. And when you’re putting one in a place where it might not get used as much, you don’t want to drop thousands of dollars on it. A good solid middle of the road toilet with good reviews is the gold standard in these cases. And in a top-rated toilet comparison you will find that the Kohler Wellworth Elongated model could be the toilet you’re looking for.

Product Overview

This toilet isn’t super flashy. It doesn’t have a self-warming seat or play music when you sit down. It just does what a toilet is meant to with a few features that make it more comfortable in the long run. First, it has a standard 12-inch rough in. That means that it will fit in most places you’re going to build a bathroom. No tight squeezes or banging you knees on a wall as you get up with this unit.

KOHLER K-3987-0 Wellworth Toilet

  • Two piece toilet
  • 2 1/8 Inch glazed trap way
  • 1.1 or 1.6 Gallons per flush
  • Why we like it: What makes this product stand out from the normal two-piece toilet is that the left hand trip lever gives the user the option of either 1.1 or 1.6 GPF.

Secondly, it has an elongated bowl. Elongated bowls are much more comfortable to sit on. If you’re a guy, a longer bowl gives more room up front where you need it. There’s also a more gently sloped angle on the front which helps reduce splatter and collateral damage. If there is a drawback, it’s that kids can’t use it very comfortably, so you may end up cleaning it more.

The third thing that gives it that little extra is the flush handle is on the left hand side. In most cases, right-handers rule, and if you’re a lefty, you’ve had to deal with that for your entire life. Not so with this toilet. If you are a southpaw, this toilet and its flushing handle has your name written all over it.

On the technical side, this toilet is a water saver, especially if you’re upgrading from a toilet that is from the late 80s. Those used to use up to 5 gallons of water per flush. It was great for clearing away the junk, but horrible for your water bill. This Kohler Wellworth only uses 1.6 gallons per flush, so you can potentially save hundreds every year.

Let’s Talk Flushing Power

When it comes to toilets, you want them to be able to handle whatever you give them. This Kohler Wellworth has a Kohler rating of Class Five, which “provides tremendous bulk waste flushing performance and best-in-class bowl cleanliness.” That is great, but what one company rates as a Class Five might only be a Class B or a three-star rating for other companies. How do you know how they measure up to each other?

Thankfully, there is a standard. In 2003, a standard called the MaP was set. It stands for Maximum Power. Over 3,000 toilets have been tested by the institute since the standard was created. If you’re interested, you can see their ratings and download them here directly from the MaP site. But you may wonder how they are tested. Here’s how they do it.

● First, they test using real world equivalents. They use a soybean paste and toilet paper which is meant to duplicate what would normally go into the toilet.
● They start with a 250 gram sample size and toilet paper and flush.
● They then increase the sample size in 50 gram increments and continue testing.
● They only stop when they reach 1000 grams (1kg, or 2.2 pounds), or when the toilet flush does not fully clear the bowl in a single flush.
That means you essentially want a toilet that has a MaP rating of 1000, which thankfully, the Wellworth does.


● Elongated bowl for more comfortable seating
● Standard rough in of 12-inches and easy installation
● 1.6 gallons per flush will save money and keep your water bill down
● Left hand flush lever makes this unit southpaw friendly
● Standard seat height is good for kids
● Comes in four standard finishes, including black, almond, biscuit and white


● Non-ADA compliant seat height may be a deal breaker for some purchasers
● Does not come with a seat or lid


If you’re looking for a middle of the road toilet that doesn’t have a lot of flash, this is a great option. It has the EPA mandated flushing volume and does a great job of clearing away waste as noted by its 1000 MaP rating. It is easy to install and comes in a variety of colors which is great for any décor. One of the most significant drawbacks is that it doesn’t come with a seat or lid, which if you’re upgrading from a round bowl model, means you have to purchase a set separately. Otherwise, this is a great pick for a primary floor powder room or an off-kitchen bathroom.

Hello. My name is Charles. I have been in the home improvement industry for a number of years. One of the most important renovations that home owners can make is a bathroom upgrade. Not only does it add significant value to your home, but it also costs a fair amount to do. Bathroom renovations are not frequently undertaken so choosing your sanitaryware can be source of enjoyment or regret for years to come. This is definitely the case for toilets.
