We're updating a guest bathroom, and the current shower/tub faucet is AquaSource. Not knowing anything about plumbing, I purchased a Delta faucet, but our plumber told us it wasn't compatible unless we want to cut a hole in the wall to replace the rough-in kit. (We don't want to do that.) The problem is that AquaSource no longer makes/sells shower/bath faucets, nor do they have any products in brushed gold, which is what we're looking for. So my question is, does anyone know if AquaSource's valves are compatible with any other brand? I know AquaSource is a Lowe's-specific brand, so I wasn't sure if there were other Lowe's brands that would work. I'd really love to avoid spending the time and money cutting a hole through my dining room wall to get to the back of the shower to replace the valve, so if anyone has any advice, let me know. Our plumber wasn't sure as he hadn't worked much with AquaSource before. Thanks!
