Integrated smart toilet or toilet plus WASHLET
There are two ways to get a bidet toilet, and this collection has both.
An integrated smart toilet, like the TOTO Neorest or the Nuvia tankless models, builds the bidet, heated seat, dryer and automatic flush into one piece. It looks clean and minimal, and most need no tank at all.
A toilet with a WASHLET seat pairs a standard two-piece bowl, such as the TOTO Drake or Aquia IV, with an electric bidet seat like the S7 or S7A. You get most of the same features, and if the seat ever needs replacing, the bowl stays put. Many of the TOTO sets here ship as a matched bowl and seat.
Flush rating and water use
Flush volume is listed in gallons per flush (GPF). 1.28 GPF meets WaterSense and the strictest state limits, including California and Colorado. 1.6 GPF is the federal maximum and still sold where local rules allow it.
Dual flush models like the Aquia IV give you 0.9 GPF for liquids and 1.28 GPF for solids. TOTO's Tornado Flush swirls water around the bowl instead of pushing it straight down, which cleans with less water.
Measure your rough-in first
Rough-in is the distance from the finished wall behind the toilet to the center of the floor drain. Most US homes are 12 inches, and that's what most models here are built for. Older homes and some condos use 10 inches, and TOTO makes 10-inch versions of the Drake.
While you're measuring, check for an outlet. Every bidet seat and smart toilet needs a 110V GFCI outlet within reach of the power cord, usually on the wall behind or beside the toilet.
Height, shape and finish
Chair height or universal height bowls sit around 17 to 19 inches from the floor, close to a dining chair, and are easier to stand up from. Standard height is closer to 15 inches.
Elongated bowls are a couple of inches longer than round ones and are more comfortable, but need more room. In tight powder rooms, a compact smart toilet like the 23.25-inch-long tankless model saves space. TOTO's CeFiONtect glaze and skirted sides keep the bowl and base quicker to clean.
Planning the rest of the bathroom
A toilet replacement is often the start of a bigger update. If you're redoing the room, pick the toilet height and the bathroom vanities together so the lines match. The freestanding bathtubs and bathroom sinks collections cover the other fixtures, and mirrors with built-in lighting are worth a look if the room gets little daylight.
