I am installing a new shower in my master bath. It will have several shower heads ( Regular, Handheld, Overhead, and body sprays ). I have been reading about mixing valves, everything I read says to go with thermastatic 3/4" valves. I am just curious about the difference and benefits of the different valves, pressure balanced are certainly much cheaper. While max flow is a consideration, I wopuld not want to run all of the shower heads at once, I would just like to used different ones at different times.

Thanks in advance for any advice.
