A manual bath shower mixer is designed to fill your bath and also run an additional shower head either on a flexible hose or a rigid riser rail. A manual valve will be either deck mounted or wall mounted and has a hot and a cold inlet running separately into the shower valve. This means you will manually choose how much hot and cold water you let through to reach your desired temperature. Manual valves are often preferable to thermostatic valves if you have a low pressure system.
