Dimensions from WHO assistive product specification for procurement (toilet and shower chairs). Choosing criteria from mobility-equipment FAQs, checked 8 Oct 2026. Not medical advice; complex needs warrant an occupational therapist assessment.
What is a shower commode chair, and do I need one?
A shower commode chair combines a shower chair and a commode in one wheeled unit. It lets you shower seated, and the seat has an aperture so it can be positioned over a toilet or used with a commode pan. The World Health Organization's assistive-product specification gives typical dimensions for an adult mobile shower commode chair: seat width around 440mm, seat depth around 430mm, seat height adjustable roughly between 400 and 550mm, about 460mm between the arms, and a safe working load around 150kg. You need one if standing in the shower is unsafe or exhausting, or if the distance between bed, toilet and shower is hard to manage. If you only need to sit while showering and never need the toileting function, a simpler shower stool or static shower chair may be enough and cheaper.
Self-propelled or attendant-propelled?
Self-propelled models have large rear wheels so you can push yourself, which suits people with enough upper-body strength who value independence. Attendant-propelled models have small castors on all four wheels and a push handle, and need a carer to move them. Also consider the seat: an open-front seat makes cleaning easier, while a closed front gives more leg support. Check the doorway question early: measure your narrowest bathroom doorway and compare it with the chair's overall width, and check you have room to turn it inside the bathroom. Folding travel models exist if you need to take one on trips or store it in a tight space.
What should it be made of, and what does it cost?
Bathroom equipment lives in moisture, so material matters. Aluminium is lightweight and rustproof but usually more expensive; stainless steel resists corrosion and is economical; plastic chairs are light but offer less strength and fewer features; coated mild steel should be avoided because once the coating wears, it rusts quickly in wet conditions. Typical weight capacities on the market range from about 250 lbs to 400 lbs (roughly 115 to 180 kg), with bariatric models going higher. Practical details to check: brakes on the wheels, a padded and wipe-clean seat, height adjustability, and whether replacement parts are available. Prices vary widely from basic folding shower stools to full tilt-in-space models, so match the chair to the need rather than buying features you will never use. If your needs are complex, ask an occupational therapist for an assessment before you buy.
