TOTO

Toilets and WASHLET+ smart toilets, WASHLET electronic bidet seats, SoftClose toilet seats, in-wall tank units and flush plates, and undermount, pedestal and wall-mount bathroom sinks. There are also a few bathroom faucets, shower trims and handshowers.

A one-piece toilet has the tank and bowl molded together, so there are fewer seams to clean and less chance of a leak at the tank-to-bowl connection. A two-piece toilet has a separate tank bolted onto the bowl; it's lighter and easier for one person to carry and install, and a damaged tank can sometimes be replaced on its own.

The rough-in is the distance from the finished wall behind the toilet to the center of the drain; measure from the finished wall (not the baseboard) to the center of one of the floor bolts. 12 in. is the most common, but 10 and 14 in. rough-ins exist. Many TOTO toilets here can be adapted to a 10 or 14 in. rough-in with a separately sold adapter, and the product page says whether yours can.

A nearby electrical outlet, since most smart toilets and bidet seats need power for heating and wash functions, and our guide notes a GFCI outlet near the toilet is standard. You also need a cold water supply line with a shutoff valve. Some smart toilets have a larger footprint than a standard toilet, so measure before you buy; a bidet seat adds the features to your current toilet bowl instead.
