I recently installed a pressure balance valve with a single handle in my new shower to replace an old dual handle system.

When the single handle is at the midpoint the pressure is good. I assume this is because it is mixing the maximum amount of hot can cold water.

However, I like to take very hot showers with the handle on close to max hot. When I move it beyond the midpoint the pressure drops. Not a lot, but enough to notice and wish it was back at max pressure.

Would switching to a Thermostatic valve fix this problem, so that even on the hottest setting I would get the max pressure?
