One- vs. Two-Piece Toilets
One-piece toilets integrate tank and bowl into a seamless, space-saving design that is easy to clean. Some low-profile models can be installed under a vanity extension when space is at a premium. Because of their special design detail, most one-piece KOHLER toilets ship with a complementary Quiet-Close™ toilet seat with Quick-Release™ functionality.
Two-piece toilets feature the traditional design of a separate tank and bowl. Two- and three-bolt installation systems provide a sturdy, level connection between the tank and bowl, making installation easy.
