You need
an Anti- Scald valve. It is a requirement in most new construction and MOST bathroom remodels, especially if used as rental.
"For about $15, you can purchase a simple valve that shuts off the water if the temperature gets too high. These valves are easy to install by removing the showerhead, screwing in the valve, and replacing the showerhead.
For about $75, you can get a valve that senses changes in water pressure and adjusts the mix of hot and cold water. A plumber must install these valves.
Some electronic anti-scald systems remember the temperature of your last shower and deliver the same level of hot water until they are reset. Other systems let you program multiple water temperatures into the unit to fit the comfort level of different users. These devices often come with an LCD temperature readout or a standard dial. They start at $150. "
