Our take on the KOHLER K-3987 Wellworth Two-piece round-front toilet, dual-flush

The Kohler Wellworth K-3987 is a two-piece, round-front toilet with a dual-flush lever on the left side of the tank. It offers 1.1 gpf and 1.6 gpf modes, and the 1.1-gallon flush uses over 30 percent less water than the full flush. The round-front bowl and 27-3/4-inch depth suit small bathrooms and powder rooms, and the side lever leaves the tank top flat for storage. It is WaterSense certified and eligible for rebates in some municipalities. Rivals in this class often put the flush selector on the tank top or use a single high-efficiency flush; the Wellworth keeps a traditional lever and gives a full-flush option.

About the KOHLER K-3987 Wellworth Two-piece round-front toilet, dual-flush

The KOHLER Wellworth is a two-piece, floor-mount toilet with dual-flush technology. A two-tone flush lever lets you choose a full flush of 1.6 gallons or a partial flush of 1.1 gallons. The lever is a left-hand nested trip lever on the side of the tank, like a traditional toilet, so the top of the tank stays free for storage.

The 1.1-gallon flush uses more than 30 percent less water than the 1.6-gallon mode. This adds up to potential savings of more than 4,000 gallons per toilet, per year. The toilet is WaterSense certified.

The round-front bowl suits smaller bathrooms and powder rooms. The trapway is fully glazed, and the toilet is made of vitreous china. It is suitable for residential use and coordinates with other products in the Wellworth collection.
