How to Install a Tub Rail or Grab Bar: Correct Height and Placement
Installing a grab bar is one of the most effective ways to make your bathroom safer. Grab bars allow users to steady themselves as they get into the shower, step over a tub, stand up from a shower seat, or any number of other everyday actions in the bathroom.
But it’s not enough just to put a bar on the wall. It needs to also be in the right location and at the right height, and must also be attached securely enough to support the weight of its users. Here’s exactly what you need to consider before installing a grab bar or tub rail.
Where to Put Grab Bars in a Shower or Tub
The best location for a grab bar in a shower or tub depends on where the user will need the most support during normal movements.
For a bathtub, a rail mounted along the wall of the tub can help with getting in and out of the tub. The MD Multi-Tub Rail is an especially practical and accessible option because it attaches to the tub, rather than requiring you to drill into the bathroom wall to install it. Its rotating handle also allows for positioning to provide a more natural, supportive grip.
In a shower, a horizontal grab bar can help with balance while standing, and a vertical bar near the entrance can provide support when stepping in or out of the shower. If the user finds it uncomfortable to stand for long periods, a shower bench like the MD Shower Bench (Backless) can also reduce the need to do so.
Before you finalize the placement of a grab bar or bars, it’s a good idea for the person who will use the bathroom to test the bar’s positioning. They should be able to reach the support easily, without the need to stretch or twist too far, which can increase their risk of losing balance.
Correct Shower Grab Bar Height for Standing and Seated Use
There isn’t one ideal grab bar height for everyone. A common starting point for horizontal shower grab bars is about three feet above the floor, but the most important factors in determining positioning are the user’s height and their mobility needs.
If the grab bar will be used while standing, it should be easy to reach and grab without the need for the user to raise their shoulder or bend down at all. For seated use, the grab bar should be reachable from the shower seat without requiring the user to lean too far to one side.
This is why adjustability can be so helpful. The MD Multi-Tub Rail is height adjustable, so the handle can be positioned based on the user’s reach and how they get into and out of the tub.
Installing a Grab Bar Into Studs, Tile, and Fiberglass
A grab bar should always be secured to a wall stud or to properly installed blocking, not just drywall.
Tile requires careful drilling to avoid cracking the surface, while fiberglass surrounds may not be thick enough to provide adequate support on their own (and will thus require additional reinforcement).
Any holes drilled in a shower or tub area must be properly sealed to prevent water from getting behind the wall and causing damage.
Clamp-On Tub Rails: Installation Without Drilling
A tub rail can provide a convenient alternative to drilling into the bathroom wall, such as in a rental, a bathroom with finished tile, or a tub that limits access to wall framing. The MD Multi-Tub Rail mounts directly onto the tub, with a rotating handle that makes it more comfortable to use. Before relying on the rail, you should test it carefully to make sure it doesn’t shift or rock.
When to Hire a Professional Grab Bar Installer
Some installations are relatively straightforward, but many others are better handled by a qualified professional. If you’re working with tile, fiberglass, or unusual wall construction, or if you can’t locate suitable framing, it’s a good idea to opt for professional installation.
Professional installation is particularly worthwhile if the person who will be using the grab bar will put substantial weight on it. In addition, those with significant mobility challenges might benefit from the opinion of an occupational therapist to determine where grab bars and other support would be most useful.
Frequently Asked Questions
At what height should a shower grab bar be installed?
A horizontal shower grab bar is usually installed about three feet off the finished floor, but the ideal height depends most on the user’s reach and how they tend to move.
Where should grab bars be placed in a tub?
For a bathtub, place grab bars where they provide support for the two riskiest movements: stepping over the wall of the tub and lowering into/rising from the tub. Adding a vertical rail near the entrance can be helpful for transitions, and a horizontal bar along the tub wall adds support once in the tub.
Can you install a grab bar without drilling into studs?
Yes. A tub-mounted rail like the MD Multi-Tub Rail can provide support without the need for drilling into wall studs, as it attaches directly to the tub using a strong clamp. For wall-mounted grab bars, however, drywall alone is not an adequate attachment point.
Do you need a professional to install shower grab bars?
It depends on the situation and your specific needs. An experienced DIYer may be able to manage a straightforward installation into properly located, easily accessible studs. However, professional grab bar installation is likely worthwhile in cases with tile or fiberglass surrounds, or if you have above-average weight-bearing needs. A professional installer can also reinforce the wall, if needed, and seal any holes near the shower properly to prevent water damage.
