Busted pipes, Aside having several cracked pipes the guest house bath hot water heater was taking up too much space, not to mention it held 30 gals of water and wasted electric to heat water 24/7.
The water supply line came out of the floor and they ran 2 lines above the shower, this was not very attractive. I decided to bring the hot and cold lines up from the crawl on the interior wall and change to on demand tank-less hot water heater which needed 10 gauge wiring and a new circuit breaker, no problem as wiring does not bother me.
This made for a much cleaner look and allowed me to increase the shower size from 32″ x 32″ to 32″ x 36″ The 4″ increase in the shower does make a difference!
