How to Choose the Best Bathroom Grab Bar

Bathroom grab bars provide stability to help maintain balance in the shower, bathtub or next to the toilet. Before buying a grab bar, you should consider several factors to help you find the right one. We'll also show you where to install a grab bar in the shower or bathroom.

Key Takeaways

  • Bathroom grab bars improve safety by providing stability in slippery areas like showers and tubs.
  • Choosing the right length and placement depends on your space, height and level of support needed.
  • ADA guidelines recommend installing horizontal grab bars 33–36 inches above the floor.
  • Always select a grab bar with adequate weight capacity — at least 250 pounds, though higher is safer.
  • Grab bars come in various shapes and materials, offering both functional support and style options.

Do You Need Grab Bars in Your Bathroom?

Bathrooms can be slippery, especially in the tub and shower area. Bathroom grab bars are sturdy safety devices that are designed to support those individuals with mobility, strength and balance impairments. The bars attach to your bathroom wall, toilet or sink and are used to prevent falls in the shower, bathtub or near the toilet. Bathroom grab bars are helpful devices for anyone needing support maneuvering in wet areas like showers.

Important Considerations

When choosing a bathroom or shower bar, there are several things you should consider. Do you have adequate space? What type of grab bar will you get? How many grab bars will you need to feel safe? Where will you place the grab bars?

When determining where to install grab bars in a shower or bathroom, think about the type of assistance that’s needed. A vertical bar helps provide stability when you need to stand or sit in the shower area or tub. A horizontal bar helps maintain balance while showering. Combining the benefits of the two, a diagonal grab bar is versatile and offers a firm grip for most individuals.

The amount of weight the grab bar can support is also an important factor. ADA guidelines state a grab bar must be able to withstand at least 250 pounds of force. While this is the minimum, it’s recommended to always use higher capacity bars as a safety factor.

A minimum of 1-1/2 inches of space must be maintained between the wall and the bar, and the gripping surface of the bar needs to be between 1-1/4 and 1-1/2 inches in diameter.

These are all factors to keep in mind when shopping for bathroom grab bars.

Types of Bathroom Grab Bars

Bathroom grab bars are designed to enhance safety and are designed for specific needs.

Wall-Mounted

Wall-mounted grab bars are accessible and sturdy, providing stability and preventing slips. They’re securely mounted to your shower wall with screws and anchors. If you need multiple grab points for better support, get a U-shaped grab bar.

Folding

Folding grab bars have a sleek and clutter-free look. They fold down or flip up when not in use. They’re ideal for small, narrow spaces.

Freestanding

Freestanding grab bars are usually floor-to-ceiling tension bars placed next to the tub or shower for support and stability. They don’t require permanent installation, so they don’t leave drill holes in your walls. They consist of an adjustable vertical pole with an attached grab bar to provide a secure grip.

Bathtub-Mounted

Installing a bathtub-mounted grab bar to the rim of your bathtub provides the additional support needed to help you in and out of the bathtub. When using a bathtub mounted grab bar, ensure that the tub’s rim is sturdy enough to bear the weight of the individuals using the grab bar.

Shower and Bathtub Grab Bar Placement

With bathroom grab bars, placement matters as much as the bar itself. The ideal placement for a shower and tub grab bars are as follows:

  • Install an 18-to-24-inch vertical bar just inside or immediately outside the shower entrance (this is the most dangerous zone). This gives you something to grab when stepping in or out.
  • Install a long horizontal bar, 24 to 48 inches and 33- to 36-inch high, along the back wall for general stability while showering.
  • For tubs, a vertical bar at the faucet end helps when stepping over the tub wall. A horizontal bar along the long wall offers supports while standing and sitting.
  • For a shower seat/bench, a horizontal bar placed beside the seat helps with sitting down and standing up safely.

Toilet Grab Bar Placement

The toilet is a high-risk area because of sitting and standing transitions. The ideal placement for toilet grab bars are as follows:

  • Install a 42-inch horizontal bar on the side wall closest to the toilet (the most important), 33 to 36 inches above the floor.
  • For added stability, install a 36-inch horizontal bar on the rear wall behind the toilet.
  • If no side wall is available, a vertical bar or a fold-down bar mounted to the floor will work as an alternative.

Caution

Bars should be anchored into wall studs for added safety.

Features of Bathroom Grab Bars
