Riosa Elongated Concealed Trapway Toilet 4.3 5 3 3
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
This product has great features but Love all the cleaning features,however I don't like the new hieght,because the seat is easy cleaning it's often lose.Worst of all it doesn't always take away the waist.That's real job. June 25, 2014
Great Product The toilet looks great, very modern and beautiful. They are very quiet when operated and easy to clean. August 18, 2014

Can other (wooden) seats be used with this toilet?

While the quick-release is interesting, it's not worth it if it means having to use a plastic seat. I'm not at all a fan of plastic seats or lids. Can a regular wooden seat be used? I'll presumably have to remove the quick-release fitting to use a different seat. Are the holes a standard spacing?
