I have 2 older Drakes with the SS114 seat that is sloped. I am getting an Eco Drake, elongated bowl, for my third bathroom but I am thinking of using a different seat for this one because the SS114 doesn't have an easy clean feature. (I can't believe TOTO doesn't have that). I want to avoid an overhang, though, so is there any seat you use that doesn't overhang? I would like a plastic, soft close, easy clean seat that does NOT have an anti-bacterial treatment. My initial Internet checks show a Bemis slow close that is 18 3/4" long versus the SS114 that is 18 1/2" long. Is 1/4" overhang unstable because it doesn't get support from the toilet rim? And if it is still stable, is it unsightly to see this overhang?
