is this possible in bathroom

It's much easier to get the right temperature with separate hot water and cold water knobs.


That's not true either. Code doesn't require single knob faucets.

Safe water temperature is controlled at the water heater.

Hopes is correct on both accounts. A single knob doesn't let one increase or decrease the flow of water without also changing it's temperature...can't have low flow hot.

A thermostatic valve prevents a sudden increase or decrease in cold water (ie. someone flushing a toilet wouldn't cause a shower to lose cold water and cause scalding). This doesn't mean one couldn't turn on the hot and have it be too hot.

There are thermostatic balancing valves with flow regulation knobs / levers.

Why hate what works?

If you have the old type where the handle controls both flow and temperature, you'll get much better control with a pressure balancing valve; the catch is they're always full on and the flow is controlled by the restrictor in the showerhead.

The thermostatic are supposedly even better, but they cost a fortune.

When the cold water drops and the value reduces the hot water, that is "pressure balance" or a antiscalding feature of the thermostatic value. The thermostatic is you set the ratio and when you turn it on keeps the same temperature at different flow rates, if you have a flow control.

I like flow control. I installed something like this for someone and they love it. It replaced an almost perfectly working old 30 year old Kohler one where you pulled it on and pushed it for off. Turning is much more control than the push and pull model. You can have all three functions, diverter, flow, and temperature coming out from one hole. Issues with water temperatures are a valve or low water volume due to pipes. If there are issues with the shower temperature changing due to toilet, washing machine, etc, it is the pipes.
