I did a search on this topic, and found a few threads, but they are old and the seat models have been discontinued. Also, I’m not interested in changing the complete toilet right now.

I have the Thetford Aquamatic toilet round bowl as I think most or all GD RV’s have. The toilet seat is poorly made, and the support bracket on the bottom has bent. I’m finding household seats aren’t an exact fit in the width. The length and bolt pattern seem to work though. Has anyone recently (last couple years) found a toilet seat that is wide enough so that the bottom of the seat stays firmly on the rim? If it’s a half inch shorter that’s okay. The one I bought yesterday had the support bracket protruding mostly over the interior of the bowl.
