I am installing a new bathroom in the house. This is going in a room formerly used as a laundry room and is between the back porch and the kitchen. My question has to do with where I put the shower and bathtub fixtures and plumbing. Formerly I have understood that the fixture valves and plumbing should have an access panel should one need to service them.
My problem is that where I would prefer to put them would be in the kitchen wall. ( Hard to access when the kitchen cabinets are in the way) The back porch wall gets quite cold and there is a beam under the floor that the outside wall rests on and I would have to bore into the beam to run any water line in.
I have been considering doing this using PEX tube. I usually use copper or PVC, but I think PEX is more robust when it comes to possible freezing.
So, do I make an access panel or not?
