Everything in there works (1) including the heat on a cold winters day. Chipping ice out of the bowl is not a pleasant chore when you just gotta go..............
Actually a relatively simple and cheap installation. The backer cement board is cheap and in 4 ft sections. The tile is all inexpensive Home Deport or similar product. The floor is a precut items, rainforest shower head, mixer valve probably Moen which means cheap 3-5 day install from tear out to finish. 7 days before use.
The most comforting thing is that the ceiling is no longer leaking water when it rains! I had a bucket catching it for weeks before I found an honest roofer who fixed my roof for a very low price:)
