Mama wants me to install an outdoor shower, utilizing the water heater 15' away for my water source. I'd tee the hot and cold water lines, obviously add shut of valves at the connections, then run copper lines along the exterior stucco and tying in a shower valve. I'm considering doing some concrete cutting to allow water to go into my flower beds, and making a box (probably using tropical materials, such as bamboo) for privacy. The exterior of my house is stucco, so it is already waterproof, but should I tile around the shower valve? Anyone have experience with installing an outside shower? Best choice of valve? Cutting in a stainless steel french drain for water collection? Any help would be greatly appreciated!
