New valve installation is usually associated with remodeling of a bathroom. The most calls we receive is to replace OLD shower valves, and there are many options and models. Depending on the hardware that is in place, if parts are available we may be able to replace with a similar model, but more often than none our customers will need a new valve.
In Miami Beach must service calls involving a shower valve have a combination of shower and tub valve.
Per code all shower valves in Miami Beach do require a shut off valve to be included in any apartment building.
There are thermostatic control and volume control combinations, but the valve that is mostly used in our jobs controls both.
