I don’t have any regrets not getting a rimless tank.
I just had a tank custom built and I thought about going rimless, but I’m terrified of a seam busting - especially since I live in a second floor apartment. Instead, I had the builder do a eurobrace.
When I was getting the quote, the builder said he’d do a 2” eurobrace, but he ended up putting on a 4” eurobrace instead. When I’m seated and looking at the tank, I don’t even notice the brace. When I reach into my tank, it doesn’t get in my way at all either. If anything, I like having it as a ledge to sit things on while I’m working.
A eurobrace certainly isn’t as visually obtrusive as one of those black plastic rims.
