This is seriously the best toilet we have ever purchased. We have owned our home for over 30 years and have had to replace our main floor toilet at least 4 times. I selected this one after researching to find out what is the best on the market. This toilet has no issues with clogging, always flushes on the first flush, and hasn't had any issues with leaking, either. And it fits well in the tight space it is in.
