How To Install Bathroom Grab Bars-Page 2
Positioning Your Grab Bars
Even a solidly anchored grab bar is
useless if it’s in the wrong place. What location is best depends on the
particular situation. If you’re installing the bars for a person with a
disability or injury, have this person help you decide which location will be
most helpful. A physical therapist or an occupational therapist also can help
with this decision. For solid anchoring, stud locations are critical too.
(Later we’ll tell you what to do if studs aren’t
available.)
Here are guidelines for placing the bars:
-
Place an 18-in. to 24-in. long bar vertically at the tub edge to assist in getting in and out of the tub. The bottom of the bar should be 32 to 38 in. above the floor. Position the bar so it can be anchored to a wall stud.
-
Mount a bar at an angle between two wall studs on the long back wall of the tub. The bottom of the bar should be about 6 to 10 in. above the top of the tub. For studs 16 in. apart, a 24-in. long bar provides a nice angle. A person can use this grab bar to help lower himself and get up again. If this bar will be used primarily by a person sitting in a bath chair, raise the bottom to about 18 in. above the tub.
-
Mount a bar horizontally about 36 in. to 38 in. above the bottom of the tub as a convenient handhold while showering.
If you simply can’t anchor to a stud, you have a few options. The best alternative is to secure wood blocking between the studs. However, this requires opening a small hole in the wall and patching it after the blocking is screwed into place. If possible, work from the backside of the tub wall, where you’re not hindered by ceramic tile or other tub finishes. If you’re lucky, you’ll have a closet or storage area where the wall patch doesn’t have to be perfect.
As a last resort, use toggle bolts or WingIts to mount the grab bar to the hollow part of the wall. The plaster, mortar or tile backer must be dry and solid and at least 5/8 in. thick.
You’re Not Done Until You
Yank-Test
Give the bars a good solid yank to test their holding
power. With a helper standing by in case the
bar comes loose, pull with all your strength. Now’s the time to make sure
the bar will hold up when it’s really needed. While you’re at it,
consider installing grab bars in other key locations. A vertical or angled bar
mounted on the wall to the side of the toilet or a vertical bar installed on
the side wall in front of the toilet helps getting up or down. The expert we
talked to recommended mounting a vertical bar beside the entry door from an
attached garage. Usually there isn’t a handrail, and negotiating two or
three steps with a bag of groceries under your arm is a lot easier and safer
with a grab bar to hang on to. Look around and you’ll find other spots
where grab bars would make everyday tasks safer and easier.
Buying Grab Bars
Grab bars are specially manufactured to
hold at least 250 lbs. when properly secured. Towel bars and other light-duty
bars are not strong enough.
Most bars are stainless steel to resist corrosion, but you can also find them with a painted finish in a variety of colors. We purchased our 1-1/2 in. dia. white grab bars at a home center. The 18-in. bar cost about $30; the 24-in. bar about $40. Thinner bars are available, but a standard 1-1/2 in. dia. bar like we’re using is just right for most people’s grip. Some bars feature added texture to reduce slipping. Here are a few guidelines for selecting grab bars:
-
Before you buy a bar to mount at an angle or horizontally on the long tub wall, locate the studs. Then buy a bar that reaches from one stud to the other, usually 32 in. long for a horizontal bar and 24 in. long for an angled bar.
-
Buy standard 1-1/2 in. dia. grab bars for most situations. Thinner bars look more like towel bars and may not be strong enough for heavy use.
-
Avoid grab bars that leave more than a 1-1/2 in. space between the bar and the wall unless there is a specific reason for using one. A person’s arm could slip into the extra-wide space and become trapped or break during a fall.
-
Ask a physical therapist or an occupational therapist to help select the right bars if you’re installing the grab bars for a person with special needs.
Purchase an 18-in. or longer bar to mount vertically at the tub edge.
Home centers keep a variety of grab bars in stock, but specialty suppliers offer the most complete selection. We’ve listed a few sources at the end of this article, or check your Yellow Pages under “Medical Equipment and Supplies.”
