Thrilled with this toilet, bought two. One word of caution, review specs carefully with your plumber first, not just the opening, but also check the spacing of your water line coming out of the wall. It has a different floor mounting - my plumber said instead of just dropping it in (a 10-minute install) he had to attach the separate fitting to the floor first. Thought he'd have to drill into our concrete slab, yet discovered a work-around using a cement adhesive. Very doable, but make sure your plumber knows the details before you order. There is limited clearance at the bottom typically near where the water line comes out of the wall. One bathroom it was not an issue, the other the water line was in the wrong place and would have hit the toilet. My plumber said in order to install we'd have to move the water line, very $$$. We ended up using the second one in another bathroom instead. Again, highly recommended, just do your homework first to avoid any surprises.
