When I originally plumbed the guest house utility room, I left all of the pipes exposed for easy access. Now that it’s been in service for almost a year and a half, I wanted to cover some of the pipes for cosmetic purposes, but still retain access to them in an emergency. In order to achieve this, I came up with a very simple solution: I build exposed studs above and below the pipes with 2×4’s, and then covered them with an easily removable section of plywood.
Once the studs were in (and reinforced with steel brackets), covering them with plywood was easy.
I then painted the plywood to match the walls, and was done. Now, when you are in the guest house garage, you don’t see all of the exposed plumbing in the utility room which the entire idea.
