Decide on the best position and location to install a safety bar or multiple bars in your bathroom, depending on your needs. The elderly or disabled may be best served by having more than one bar to easily get in and out. Common positions are horizontal bars either on the front wall of the shower/bath area above the faucet and faucet control, on the back wall opposite the faucet, a vertical bar on the outside edge of the shower enclosure for easy entrance, or a diagonal bar on the longest wall of the shower for aid in and sitting and standing. Around the toilet, it is ideal to have at least one bar installed on an adjacent wall.
Keep in mind when deciding on positioning that the strongest support comes from installing the bar’s hardware into wall studs. Generally, wall studs will be 16” apart on center. For this reason, 16” or 32” grab bars are ideal size choices. Horizontal safety bar height, generally, should be anywhere from 32” to 38” from the bottom of the tub or from the bathroom floor by the toilet.
Try placing each bar where you think it is needed. Ensure that a horizontal or vertical bar will be installed so that it is easy to grab when entering the bathroom. Sit in the dry tub or shower to ensure that a diagonal bar will be within reach and provide maximum stability when sitting or standing.
