Curvy and compact, this one-piece toilet makes a strong design statement. A space-saving tank curves seamlessly into a round-front bowl for a low-profile silhouette. This toilet includes ergonomically designed seating, and a lid with an indented area to keep fingers from touching the seat. At 1.6 gallons per flush, this Rialto toilet delivers strong, quiet flushing performance.

  • The smallest toilet from front-to-back in the industry is perfect for small spaces
  • Rim Jet flushing technology
  • Round-front bowl
  • 12 In. rough-in
  • Includes French Curve toilet seat and trip lever
  • Includes flexible supply line
  • Single-flush gravity uses the force of gravity and a precision-engineered tank, bowl, and trapway to create a strong siphon during flushing

Rated 3.6 out of 5 by 65 reviewers.
Rated 4 out of 5 by Works Fine Works fine no surprises. Fits in the powder room space. Would purchase again March 18, 2014
Rated 5 out of 5 by Kohler Black Toilet Good looking; sleek, good operation, slightly noisy when tank is filling. December 14, 2010
Rated 5 out of 5 by Beautiful, compact alternative to everyday toilets After reading some negative reviews about flushing problems with the Rialto, we bought one anyways because it was the least expensive one piece, black, round toilet on the market. Installation was easy enough (no wax ring in box), and flushing has been problem-free and adequate. Toilet is installed on first level of house with basement with long, meandering drain line to sewer (that was our main concern). This toilet is beautiful and very functional. One thing I love about the seat (even though it's plastic) is that it is actually very comfortable and feels larger than it is. Over all, would definitely buy again. August 28, 2012
Rated 5 out of 5 by best toilet I ever bought I called, ordered, drove to the store, paid, the item was loaded in my truck for me and I drove away. It couldn't have been more simple or took less time. The entire staff was very helpful, friendly and professional. September 23, 2014
Rated 5 out of 5 by great toilet This toilet was the rite color for my Wifes new bath room. She has one in Black also. If you want to make her very happy you need to make some in Red. September 23, 2014
