Shower chairs and tub benches
Look for the weight capacity, seat width and a height-adjustable range that suits the user. For tub benches, check the bench fits across your tub wall.
Sizing & Weight Capacity Guide
How to choose equipment with the right weight capacity, width and height – and how to measure before you order.
Choose in four steps
-
1
Check the weight capacity
Most important
Choose equipment rated comfortably above the user's weight – a margin of at least 10–20% allows for movement and sitting down heavily.
-
2
Check the width
Seat and frame
Seat width should be at least the user's hip width plus 2 inches. Then check the frame still fits your doorway, tub or toilet space.
-
3
Check the height
Seat and handles
The user's feet should rest flat with knees at about 90 degrees. Handles should sit at wrist height with arms relaxed.

How to measure
Use a soft tape measure and write the numbers down before you shop.
| Measurement | How to measure it | Used for |
|---|---|---|
| Hip width (seated) | Sit on a firm chair and measure across the widest point of the hips or thighs | Shower chairs, commodes, seating, wheelchair cushions |
| Seat height | Measure from the floor to the back of the knee while seated with feet flat | Chairs, commodes, raised toilet seats, benches |
| Wrist height | Stand upright in everyday shoes, arms relaxed; measure from the floor to the wrist crease | Walkers, rollators, canes |
| Doorways and spaces | Measure the narrowest doorway or gap the item must pass through, and the floor space where it will stand | Rollators, commodes, beds, lift chairs |
| Tub wall height and width | Measure the tub wall from the floor outside, and the inside width of the tub | Tub transfer benches, shower chairs |
What to look for, by product type
Commodes and raised toilet seats
Check the capacity, the width between the arms and the seat height. Raised seats must fit your toilet bowl shape (round or elongated).
Walkers and rollators
Handle height should match wrist height. For rollators with a seat, check seat width, seat height and the folded size for your car.
Beds, rails and mattresses
The capacity of a bed or frame must cover the user plus the mattress. Bed rails must match your mattress thickness and bed type.
Chairs and seating
Seat width at least hip width plus 2 inches, seat depth that supports the thighs, and a capacity above the user's weight.
Scales
Choose a capacity above the user's weight and a platform wide enough to stand on comfortably and safely.
Safety first
Never exceed a product's stated weight capacity, assemble and adjust it exactly as described in the manual, and check fittings regularly. These products are daily living aids, not medical treatment – ask a healthcare professional if you are unsure what is right for you.
