Delightful! This toilet solves so many of my issues. The one button flush works simply and efficiently every time. My house is over 100 years old and has a 14" ro, which I have not been able to find.  So 12" standard r.o. it is. This means I live with a 2" gap between the wall and the toilet. A one-piece toilet is easier to clean and stronger than a two piece with bolted tank.  This model is wider than the old one, adds to a feeling of stability.  front to back is under 26" so the door does not hit it anymore. I can actually replace the door with a new one that is complete. This toilet is shorter than the new chair or ADA height which is great for short people like me and for anyone suffering with constipation. My tall husband will adapt.
