Struggling to reach the valve installed too high or bending too low to open, close, or regulate the water temperature makes your time in the bathroom a bit uncomfortable. This is why determining the tub shower valve rough in height is essential.
The standard rough-in height for a tub shower valve is 28 inches. This is considerably lower than the shower valves in shower stalls, usually installed 48 inches from the bathroom floor. The 28-inch rough-in height for your tub shower valve ensures you can comfortably reach the valve.
Discover important details about tub shower valve rough-in height, including factors determining where to install the valve below. Also, the post covers the appropriate heights for other bathroom fixtures.
Tub Shower Valve Rough In Height (Quick Answer!)
Before further exploring the tub shower valve rough-in height, below is a table of different shower fittings heights.
| Fixture | Height From The Shower Pan | |
| 1. | Showerhead | 72 inches or more |
| 2. | Shower valves in tubs | 28 inches |
| 3. | Shower valve in the shower stall | 48 inches |
| 4. | Shower tap | 20 inches |
| 5. | Shower grab bars | 36 inches to 42 inches |
Typically the rough-in height for a shower valve depends on whether your shower is in a shower stall or the bathtub. The installation is usually done at a higher height if fitted in a shower stall (48 inches) compared to 28 inches when fitted in a bathtub.
You must also account for the user’s height, so position the shower valve with short, medium, and tall people in mind.
What is The Standard Shower Mixing Valve Rough In Height?
A majority of shower mixing valves are typically installed 75 cm to 100 cm ( 29.5 inches to 39.3 inches) from the floor. Note that this height will vary based on your shower’s height; you can adjust the positioning to accommodate your preferences and needs.
Factors Influencing the rough-in height of tub shower valves
Consider the factors below when determining the proper position for your tub shower valve.
1. Plumbing Codes
Before starting any bathroom installations, familiarize yourself with the local plumbing codes to ensure you meet the requirements and standards. Remember that plumbing codes vary according to jurisdictions.
For instance, showerheads must be installed at least 72 inches from your shower pan in some areas and 76 inches in others. If unsure, seek the help of an expert. Ignoring your area’s plumbing codes can be disastrous and even land you in trouble with the authorities.
2. Shower Controls Location
The shower controls location must also be accounted for, making sure they are not in the direction of the water splash and are installed beneath the showerhead. If the rough-in height of the shower mixing valve and shower controls are positioned inappropriately, interfering with each other, you must make the necessary adjustments.
3. Shower Seat Presence
The standard 28-inch rough-in for a tub shower valve is unsuitable if you have a shower seat. Shower seats are designed for people who cannot comfortably use regular bathtubs, such as pregnant women and individuals with disabilities.
Depending on your tub, you can install a seat at different heights, with some allowing seats measuring 17 to 19 inches above the floor. Therefore, you will need to increase the rough-in height from the tub shower valve to make it more accessible.
4. Number of Showerheads
If you want multiple two or more showerheads in your bathroom, you must decide whether you want them to use a single control or separate ones. Having one control may be more economical, but it means all the showerheads will run whenever you turn the valve on.
You can install multiple shower valves but ensure you determine the proper rough-in for each.
5. Personal Preference
You must also consider your comfort when choosing where to install your tub shower valve, making sure you can easily access it. For this reason, make the necessary adjustments but do not ignore the plumbing codes.
The standard rough-in for tub shower valves may not be ideal if you have people over 6 feet in your home. In that case, you must adjust the height to make it comfortable for them.
However, do not forget the shorter individuals as you make the adjustments because they will not need to feel comfortable.
How To Measure Tub Shower Valve Rough-In Height
To measure the rough-in height of your tub shower valve, get a level and measuring tape, then follow these steps:
- Locate the valve center location on your bathroom wall. This is typically indicated on the plans or instructions for the plumbing installation.
- Using measuring tape, determine the distance between your bathroom floor and the valve’s center. Make sure to take this measurement at the exact location where the valve will be installed.
- Use the level to ensure the valve location is perfectly level to ensure your shower valve functions properly and water flows correctly.
- Record the measurement and mark the height on the wall. This will be the rough-in height for the valve.
Note
It’s important to note that the rough-in height can vary depending on the type of valve being installed and the specific plumbing installation instructions. Referring to the manufacturer’s instructions or a licensed plumber is wise, as it ensures you will install the valve at the correct height.
Another aspect worth knowing is that the position of shower valves in bathtubs is usually lower from your bathroom floor because it needs to connect to the tub and bathtub tap.
To get the best possible rough-in height, take your height and add 12 inches to it for a bathtub with a shower. If your bathtub does not have a showerhead, add 12 inches to your height when seated.
Summary of Tub Shower Valve Rough In Height
Although you can make some adjustments, the rough-in height for your tub shower valve should be 28 inches. Ease of accessibility and plumbing are the most vital aspects to consider when choosing the installation spot for your tub shower valve.
