The shower valve should be at least 27.5 inches from the floor, which is 78% of your height, and no more than 36 inches from the floor, which is 110% of your height. In shower enclosures where the shower head is mounted 72 inches above the floor, the valve and handle should be 48 inches above the floor. For shower enclosures, install the valve at a standard height of 48 inches or 4 feet. Valves should be approximately 24 inches for tub showers and 48 inches for walk-in showers, which are just recommended heights.
The standard height of the valve in a bathtub shower enclosure is 28″ or 2’4″. The height of the bathtub shower valve is 28″ (2′ 4″) inserted into the shower floor of the bathtub. Under normal conditions, the shower faucet should be installed at a distance of 38 to 45 inches from the floor. If the shower is also used as a bathtub, the situation will be different, in which case you should place the valve 8 to 18 inches above the bathtub faucet.
If your shower is also a bathtub, make sure the valve is low enough for bathers to use, but you can place it about 45 inches off the ground if your shower doesn’t have a bathtub. The shower seat should be installed so that it is 17 to 19 inches from the finished section of the shower floor. The height of the shower valve from floor to floor should be such that both the shortest and the tallest person can easily use it. Installing a height-adjustable shower valve ensures that you can shower on all parts of your body without having to shower excessively with your hands.
The height-adjustable shower valve can tilt the spray upside down, making it easier to rinse out shampoo and conditioner. Valve and faucet placement is important for comfort and ease of use in any shower, but there is no exact height needed for a particular fixture. In a shower stall with a 72″ head and a 48″ valve, the length of pipe between fittings is 24″ or 2 feet. The minimum height of the shower control area is 38 inches from the floor.
The minimum height of the above-ground shower control area is 38 inches above the ground. The ideal height range for shower controls is 40 to 50 inches above the floor. Standard shower heads should be approximately 80 inches above the floor, and shower controls should be 38 to 48 inches above the floor, or 8 to 18 inches above the tub faucet, if applicable. For example, if local regulations require the shower head to be set at 72 inches, but someone in the household is taller than 72 inches, you can adjust the height to accommodate the tallest member of the household.
