One-piece toilets offer exceptional performance in a smaller footprint. They have lower-profile tanks that can help a petite bathroom seem more spacious, and they fit conveniently under many bathroom countertops. Some one-piece toilets have a compact elongated bowl, which will fit in the space of a round-front toilet.
One-piece toilets are easier to clean than two-piece toilets, thanks to their bowl design and seamless tanks. And models with concealed or skirted trapways are easier still. They’re also simpler to install, because you don’t have to attach the tank to the bowl. And most KOHLER one-piece toilets include a toilet seat.
