I installed a shower head with a on/off valve on it.
Seeing as how we only have the shower stall and not a bathtub I also installed one of these http://amzn.to/2b6jRMJ
where the line comes out of the "Faucet Valve Diverter". One thing I don't like is hopping in the shower and having to adjust the water temp while I'm in there. So with this thing installed, I can divert the water down (like a faucet) and get the temp the way I want it! I'm planning on running a short piece of PVC pipe down to bring it closer to the shower floor (less splashing).
