I have a Toto Promenade on order. Because of a new floor, I need to raise the flange height. I've looked at the Set-Rite kit, and it seems they've put a lot of thought into making it work. My one concern was the adapter they use, which goes down to 2 1/2" I.D. Does this cause any issues with Toto toilets (the Promenade specifically)? Any other feedback on this kit?
