Riosa Elongated Concealed Trapway Toilet 5 5 1 1
Great style and performance We were looking for a new toilet that would flush without clogging, and also do away with leaky tank bolts. We thought the tall tank made sense. It would have been nice if it came with a small tube of silicone, since I had to go buy a tube. Overall, it looks great in our bathroom and the strong efficient flush can't be beat! April 6, 2014
