Tub and Shower valves are called ‘Tub and Shower’ valves because they can be used for both a Tub and Shower combination and a Shower installation. This installation shown in the picture was for a Shower. The bottom outlet which normally serves as the Tub spout is capped. Also, in East Sugar Land all new installation are to have a shut-off valve at the valve so that the valves can be serviced without having to shut the water off to the whole house. These shut-off valves shown here are the stainless steel screw on left and right and can be operated using a flat head screw driver.
