Main considerations for a custom shower. For the sake of comparisons, I’ll be using technical information from California Faucets.
First, select the main control valve.( Either pressure balance or thermostatic. I’ll list the advantages to each type.
- Thermostatic: Anti-scald, Constant temperature delivery, Maximum flow rate is up to 3 times greater than that of the pressure balance valve, Individual volume controls (great for multiple shower heads, large shower heads or body sprays)
- Pressure Balanced: Anti scald, constant temperature delivery. Price
Second,
Both valves will maintain constant water temperature (no more temperature fluctuations). Both valves have anti-scald features. BUT, the thermostatic valve has volume control and will allow much greater maximum flow. (up to 3 times greater)
