We are very pleased with this unit. Needed a smaller-than-average toilet for our very compact shower room. This is perfect! Installation was pretty easy for our contractor, no real difficulties. It looks great and doesn’t feel significantly smaller than a regular toilet to sit on. I was nervous based on a few reviews, claiming it was like a kids’ toilet — but that’s not our experience. We’re not tiny people either (5’8”-5’9” and ~170lbs), just average medium to tall build. Can’t comment on longevity, since we’ve only had it a week. But pleased so far!
