Product Description

This Wellworth dual-flush toilet combines water savings with powerful flush performance. An innovative two-tone flush lever offers the choice of 1.1 or 1.6-Gallons per flush; the dual-flush lever is located on the side of the tank like a traditional toilet, leaving the top free for storage. The high-efficiency 1.1-Gallon flush reduces water use by more than 30-Percent over the 1.6-Gallon mode, which adds up to potential water savings of more than 4,000-Gallons per toilet, per year. Technology Dual-flush technology allows you to choose between a full- or partial-flush. Installation Standard 12-inch rough-in. Three-bolt installation. Water Conservation & Rebates WaterSense toilets meet strict EPA flushing guidelines, including using at least 20 percent less water than 1.6-gallon toilets. Eligible for consumer rebates in some municipalities.

A toilet that Looks and Works Great!

A toilet that Looks and Works Great!
I purchased this toilet for our bathroom remodel (our one and only bathroom in our small Cape Cod style home). I didn't want to spend a lot of money, but did want something more than just the standard builder's grade toilet. The lines on this toilet make it look petite and distinguished (instead of boxy) in my small bathroom. The bowl, though it uses a standard round seat, seems a little wider than our previous toilet and seems to improve my husband's "aim" so less cleaning. I always wanted a dual flush toilet, but before had only seen them with the button on the top. Since my bathroom is so small, I really needed the handle on the side as I keep a box of tissues on the top of the toilet. The first stage flush works great. I discarded the toilet seat that came with it and installed a black soft seat. Very happy with this choice!

1.0 out of 5 stars Horrible experience! Terrible noisy when flushing and refused to return! No toilet seat!
Reviewed in the United States on July 11, 2022
Terrible quality control and customer service! Worst of all, eFaucet replied me to refuse returning since it was installed! But how can I know it is so noising without installing it? I wasted hundred dollars installation fee by myself already but they even refused refunding toilet fee to me!!! Also, it was shipped to me without toilet seat, and argue I didn’t read carefully – Amazon picture showed the seat on! Nobody thinks about checking it before installation, it is very inconvenient when you couldn't find toilet seat anywhere after it was installed! I have to match a seat by myself even if there is no flushing noisy issue! Terrible experiences, and please never purchase KOHLER brand from eFaucet any more.
