KOHLER Wellworth Toilet Review

1.7/5 - (51 votes)

In this Kohler Wellworth Toilet Review, we are going to explain the details in 5 subheadings. It is a two-piece, standard-height toilet. Also, it comes with a single flush system delivering 1.6 gallons per flush. The bowl is elongated for comfort. But, the height of the bowl is only 14 ½ inches plus the height of the seat which must be purchased separately. It, therefore, does not meet ADA compliance for installation in restrooms to which the public or employees has access.

The two-piece toilet is made of vitreous china. Additionally, the three mounting bolts to attach the cistern to the base are pre-located to make the installation easier and quicker.

Although the Kohler K-3978-0 does lack some of the features of more expensive toilets it does have an exceptionally high-rated flush system. Also, the flush is classified as Class 5 which means that it has a very high bulk waste cleaning capacity.

Kohler Wellworth Toilet: Review


The shape of the Kohler K-3978-0 is quite plain. However, the look is enhanced by some simple curves on the cistern. The toilet is a standard configuration two-piece toilet with an elongated bowl for additional comfort, manufactured in vitreous china.

Flushing System

The 1.6 gallons per flush is a single flush design. The flush water is delivered at high pressure through a canister flush valve. Additionally, the toilet is rated as Class 5 for the efficiency with which it cleans bulk waste on flushing. The flush is triggered by a chrome-plated left-hand trip lever. It is one of our top-rated flushing toilets!


Due to a combination of a fully glazed 2 1/8 inch trap way plus the highly efficient 1.6-gallon flushing action, the Kohler K-3978-0 has one of the most efficient cleaning abilities in its class. It is designed to clean the bowl on every flush out of clogging or the need for a second flush.


The single-action flush system uses 1.6 gallons of water on every flush.

Ease of Installation

The Kohler K-3978-0 uses the standard 12-inch rough-in for the waste pipe. As it is a two-piece toilet, the initial installation is easy. First, install the toilet to the waste, then add the cistern. The toilet does not come with a seat, this needs to be purchased separately. To check the dimensions for the installation of the toilet plus the spacing for the seat, check out this specification page from Kohler.
