We bought a new house that we're slowly learning was the victim of a rather cheap remodeling job. So, I'm slowly patching thing up.
One task is our shower enclosure. It's made up of some sort of panel system, with a matching shower base. It's the same material that the bathroom vanity top is made out of. I'm guessing it's something like Corian, though likely a lot cheaper of a product. Can anyone ID what this is?
The issue is that the corners of the shower walls had these inside corner trim pieces that had most of the caulking failing. I wanted to remove them, clean off the caulk, and re-caulk. Unfortunately, while one came off, the other came off in pieces as this material isn't terribly strong. It appears to be some sort of fibrous plastic material.
The problem is I have no idea what the product is, so don't know where to even begin looking for a replacement trim piece.
Bonus points if anyone can tell me more about the actual wall panels. Most stand-up shower systems I've seen have redundant joint overlaps to keep water from getting behind them. I'm pretty sure the shower pan has that, but can't tell on the wall panels themselves.
