I had some smaller ones my contractor put in when we finished off our basement. These larger ones were to allow access to a valve replacement and plumbing repair. My only suggestion would be to ship the units in a box that could double as a template for cutting the hole in the drywall. I made my own with cardboard but I think a template might be useful to some buyers.

It came with the corners bent in. Luckily my contractor was able to pull them out.

Terrible customer service

Bad

Terrible customer service and late late late delivery
