Thermostatic shower system 1/2" enough or need 3/4"??
We are doing a remodel and will be installing a shower system with four body jets, a rainfall showerhead and a handheld shower wand. I have three options, and have been debating which to pick. Obviously the third is the best but also much more$$. So here goes
1st option is 1/2" main thermostatic valve with 1/2" stop valves for the jets, shower head and wand.
2nd option is 3/4" main thermostatic valve with 1/2" stop valves for the jets, showerhead and wand.
3rd option is 3/4" all around.
The company that makes the 1st option claims they 1/2" valve is better than most 3/4" valves made by the competitor but is that really true? Do I really need 3/4" or is 1/2" enough to run the jets and the head at same time?
