Choosing a Shower Chair: Height, Back, Drainage

Mobility & Comfort · Buying guide · 5 min read

Seat height decides whether a shower chair helps or becomes something to climb out of. Everything else — back, arms, drainage — follows from getting that one measurement right.

Adjustable shower chair with back and non-slip feet
Adjustable legs matter more than they look. Bath floors are rarely level and the right height is rarely the middle setting.

Measure before you shop

Have the person sit on a firm dining chair with feet flat. Measure from the floor to the back of the knee. That number, give or take a centimetre, is the seat height you want.

Too low and standing up becomes a lift from the thighs. Too high and the feet dangle, which is unstable the moment someone reaches for a tap.

Check the measurement against the chair’s adjustment range, not its maximum. A chair that only reaches your number at full extension is at its least stable exactly where you need it.

Back or no back

A backless stool is lighter, easier to store and fine for someone who can sit steadily and only needs to rest.

A back is worth the space if the person washes sitting down for more than a couple of minutes, leans while washing hair, or has any dizziness on standing. It also gives something to push against when rising.

Arms, drainage and feet

Arms help with sitting down and standing up but make sideways transfers from a wheelchair harder. Choose based on how the person actually gets on and off.

Drainage holes are not a detail. A flat seat holds a film of water and becomes slippery. Look for a contoured seat with holes.

Feet should be wide rubber tips, not narrow plastic. Check them every few months — worn tips are one of the commonest causes of a chair sliding.

Fitting it into a small bathroom

Measure the tub or cubicle floor before ordering. A chair that fits the space but leaves no room to stand beside it makes helping harder.

If a helper is involved, leave a clear side for them. If the chair is in a bath, a bath board or transfer bench may be a better answer than a chair.

Check before first use

  • All four legs locked at the same height, pins fully engaged.
  • Chair does not rock when pushed at a corner.
  • Feet clean and dry — soap residue makes rubber slip.
  • Grab bar within reach of the seated position, not behind it.
  • Shampoo and soap reachable without leaning.
