If you've already decided a tub transfer bench is the right seat — because you have a tub or tub-shower combo and stepping over the wall is the hard part — this guide is the next step. It covers exactly how to measure for one, set it up safely, and use it with correct technique, plus how to choose between standard, sliding, and bariatric models.
Not sure a transfer bench is what you need? Compare it against shower chairs and bath benches in our complete bath seating guide first.
What a transfer bench does (and why the fit is critical)
A transfer bench straddles the tub wall: two legs stand outside the tub and two inside. The user sits down on the dry, outer portion, then slides across and lifts their legs over the wall — so they never step over it or stand on a wet surface. Because it bridges the wall, getting the measurements right is what makes it safe. A bench that's too wide, too narrow, or wrong-height doesn't seat squarely and can rock.
How to measure your tub before you buy
- Tub wall height: measure from the floor to the top of the tub wall. Most benches adjust across the common range (~14–21 in.); confirm the model covers your height.
- Tub width (inside): measure the interior width so the two inner legs land flat on the tub floor, not on a slope or ledge.
- Outside clearance: measure the floor space beside the tub — the outer legs need a stable, non-slip spot to stand.
- Seat width and depth: match to the user's size; bariatric users need a wider seat (below).
- Reversibility: check whether the backrest and any armrest can be set up for a left- or right-hand transfer to match the user's stronger side.
Standard vs. sliding vs. bariatric: which model?
| Type | How it works | Best for | Typical capacity |
|---|---|---|---|
| Standard transfer bench | Fixed seat; user slides across the surface | Most users who can shift their own weight | ~300 lb |
| Sliding transfer bench | Seat glides on a track; the bench does the moving | Weaker users, one-sided weakness, or caregiver-assisted transfers | ~300–400 lb |
| Bariatric transfer bench | Reinforced frame, wider seat | Higher-weight users | ~400–600+ lb |
A sliding bench is worth the extra cost when sliding across a fixed seat is itself difficult — after a stroke, with significant weakness, or when a caregiver is doing much of the work. A bariatric bench is a safety requirement, not an upgrade, for heavier users; never exceed the stated weight rating.
Setting it up safely
- Adjust each leg so the seat is level despite the tub wall — the outer legs will be longer than the inner ones.
- Confirm all four feet have intact non-slip tips and sit firmly; the outer feet should be on a non-slip mat if the floor is smooth.
- Set the backrest and armrest for the user's stronger side.
- Position a mounted grab bar within reach for the transfer — the bench is for sitting, the grab bar is for steadying.
- Add a handheld showerhead so the user can wash seated without turning.
The transfer technique, step by step
- Back up to the outer seat until you feel it against your legs; reach back for the armrest or grab bar and sit down under control.
- Scoot back fully onto the seat so you're stable.
- Lift one leg at a time over the tub wall — use your hands to assist the weaker or operated leg if needed.
- Slide (or, on a sliding bench, glide) across to the inner seat.
- Wash with the handheld sprayer.
- To exit, reverse it: slide to the outer seat first, bring your legs out one at a time, then stand using the grab bar and armrest — never push off a wet wall.
Common mistakes to avoid
- Stepping over the wall anyway — defeats the whole purpose; always sit and slide.
- Standing up while still over the tub — slide out first, then rise.
- Relying on a towel bar — only a mounted grab bar is safe to pull on.
- Skipping the mat under the outer feet on smooth flooring.
- Exceeding the weight rating — move up to a bariatric model instead.
Frequently asked questions
How do I know a transfer bench will fit my tub?
Measure your tub wall height, inside width, and the floor space beside the tub, then match those to the model's adjustable range and footprint. Most benches fit standard tubs, but always check.
Do I need a sliding transfer bench or a standard one?
Standard works if the user can shift their own weight across the seat. Choose a sliding model if that slide is hard — after a stroke, with weakness, or for caregiver-assisted transfers.
Can a transfer bench be used in a walk-in shower?
A transfer bench is designed to bridge a tub wall. In a curbless walk-in shower with no wall to cross, a shower chair is usually the better fit — see the bath seating guide.
Which way should the bench face?
Set it up so the user leads with their stronger side and can reach the grab bar and controls from the seat.
Does Medicare cover a transfer bench?
Original Medicare generally does not cover transfer benches, treating them as convenience/safety items; FSA/HSA often applies. Check your specific plan.
