Shower Chair vs Transfer Bench vs Tub Bench: Which One Do You Need?

Three products, similar prices, similar photographs, and a great many households buy the wrong one. The distinction is not subtle once you see it, but almost nothing in the way they are sold makes it clear.

One question sorts it out: is the difficulty standing up, or getting in? A shower chair solves the first. A transfer bench solves the second. Buying a chair for a getting-in problem leaves the person facing exactly the obstacle they could not manage — now with a chair in the way.

The three products 🪑

• Shower chair. A seat with four legs that stands inside the shower or the tub. The person gets in on their own feet and then sits. Some have backs, some have arms.
• Transfer bench. A wider seat with two legs inside the tub and two outside, spanning the rim. The person sits down outside the tub and slides across. The rim is never stepped over.
• Tub bench. A seat sized to sit inside a bathtub, usually wider and lower than a shower chair, sometimes with a back. The person still has to get in.

The transfer bench is the odd one out, and it is the only one of the three that removes an obstacle rather than providing a place to rest.

The question that decides it ❓

Watch one shower or bath, from beginning to end, and note where they hesitate.

The top two rows account for most households, and they point at different products. If the tub rim is the obstacle, a chair inside the tub does not help at all — they still have to get past the rim to reach it, on one wet foot, with nothing to hold.

Side by side 📊

Two rows deserve attention before you buy. A transfer bench cannot be used with a glass shower door — the door frame runs exactly where the bench needs to cross. And a transfer bench leaks water onto the bathroom floor unless you plan for it, because part of the seat is outside the tub by design.

How a transfer bench actually works 🛁

Worth spelling out, because the mechanism is what makes it safe and most product photos do not convey it.

1. They sit down on the outside end, on dry floor, at normal seat height — a movement they can already do.
2. They lift one leg over the rim while seated, which is a completely different action from doing it standing on the other foot.
3. Then the second leg. Still seated, still stable, still holding on.
4. They slide along the bench to the inside end, under the shower.
5. Reverse to get out, ending seated on dry floor rather than stepping onto wet tile.

Notice what is absent: at no point does the person stand on one leg on a wet surface. That single-footed moment is where most tub accidents happen, and the bench designs it out rather than supporting it.

When a shower chair is right 🚿

• A walk-in or low-threshold shower, where getting in is not the difficulty.
• Standing endurance is the limit — they can get in fine but cannot stay upright for a full wash.
• Balance while eyes are closed, which is a specific and commonly overlooked risk during hair washing.
• Dizziness, particularly with heat, or with medication that lowers blood pressure.
• Small bathrooms where a bench simply will not fit.
• Shared bathrooms, since a chair lifts out in seconds and a bench does not.

Within shower chairs the meaningful choice is arms or no arms, and it follows the same logic as everything else here: if standing up from the seat is hard, arms matter far more than any other feature. A back matters if they cannot sit unsupported, or if they need to lean while washing.

Where a tub bench fits 🛀

The least-discussed of the three, and occasionally exactly right. A tub bench sits inside the bathtub, wider and usually lower than a shower chair, for someone who can still manage the rim but cannot get down to the tub floor or back up from it.

• Best for: someone whose legs still work well enough to step over, but not to rise from a full squat.
• Advantage over a transfer bench: it is entirely inside the tub, so water stays where it belongs and a glass door is no obstacle.
• Advantage over a shower chair: wider and more stable in a tub, and designed for the curved tub floor.
• The limit: it does nothing at all about the rim. If crossing that is hard now, it will only get harder.

The curtain problem 🚿

This catches people out after they have bought, so it belongs before the purchase.

• A transfer bench cannot work with a glass shower door or a fixed screen. The frame sits exactly where the bench must cross. Removing the door is usually the answer, and it is a bigger job than the bench.
• With a curtain, the water needs managing. The correct method is to run the curtain inside the bench — between the seat and the tub interior — so water runs into the tub while the outer end stays dry.
• A second short curtain or a split curtain makes this considerably easier, and some benches come with one.
• A non-slip mat outside the tub catches what escapes, and it needs to be a proper rubber-backed mat rather than a towel.
• A handheld shower is close to essential. A fixed overhead head aimed at the middle of the tub sprays straight past someone sitting on the outer end.

What to check on any of them 📋

• Weight capacity with real margin over the user’s weight, not a figure sitting right at it.
• Seat height adjustable through 17 to 19 inches, the band most adults can rise from.
• Rubber tips on every leg, present and not perished. This is the most common defect on secondhand equipment and it turns a safety aid into a hazard.
• Drainage holes in the seat so water does not pool.
• Independent leg adjustment on a transfer bench, because tub floors and bathroom floors are rarely level with each other.
• Aluminum or coated frame. Painted steel corrodes from inside the tube in a wet room.
• Tool-free assembly and adjustment, so the height can be changed as needs change.
• Measure the tub — inside rim to inside rim, and the floor space outside — before ordering a bench.

When you need two 🔀

Occasionally the right answer is not one of the three but a combination.

• Transfer bench plus a grab bar. The bench handles the rim; a vertical bar at the entry gives something to hold during the slide. This pairing is close to standard.
• Shower chair plus a grab bar within reach of the seated position, for sitting down and standing up.
• Bench downstairs, chair upstairs, where there are two bathrooms with different fittings.
• Chair now, bench later — but if the trajectory is clear, buying the bench first usually saves buying twice.

Whichever you choose, none of these three gives the person anything to hold while moving. They provide a place to be, not something to grip — and a grab bar is what fills that gap.

Common mistakes (with fixes) 🔍

Pro tips 💡

• Watch one full bath or shower before buying anything. Where they hesitate is the answer, and it takes ten minutes.
• Measure the tub inside rim to inside rim, plus the floor space outside, before ordering a bench.
• Ask about a loan closet first. All three are heavily donated because they are so often needed temporarily.
• Check every rubber tip on anything secondhand, and replace missing ones before use.
• Set the height so their feet rest flat on the tub floor or bathroom floor when seated.
• Buy the handheld shower at the same time as a bench. You will need it, and a second order costs more in shipping than the part.
• Try it dry first, fully clothed, before the first real use. Problems are much easier to solve when nobody is wet and cold.

What this looks like in real life 🏡

“The chair was inside the tub she could not get into”

A well-reviewed shower chair, correctly assembled, sitting in a tub she had stopped being able to climb into three months earlier. Nobody had asked which part of bathing was the problem. A transfer bench replaced it and she bathed alone again the same week.

“The bench arrived and the door was in the way”

Sliding glass doors on the tub. The bench physically could not span the rim. Removing the doors and fitting a curtain cost more than the bench and took a weekend. Two minutes of looking would have caught it.

“We flooded the bathroom for a fortnight”

Bench fitted correctly, curtain hung outside it as it always had been. Water ran down the curtain and off the outer end of the bench onto the floor, every time. Tucking the curtain inside the bench fixed it completely — a detail nobody had mentioned and which appears in no packaging.

Frequently asked questions ❓

What is the difference between a shower chair and a transfer bench?

A shower chair stands entirely inside the shower or tub, so the person has to get in on their own feet before sitting down. A transfer bench spans the tub rim with two legs inside and two outside, so they sit down on dry floor and slide across without ever stepping over the rim. The chair solves standing to wash; the bench solves getting in.

Which is better, a shower chair or a transfer bench?

Neither — they solve different problems. Watch one bath or shower and note where the hesitation is. If it is lifting a leg over the tub rim, you need a transfer bench, and a chair will not help at all. If they get in fine but cannot stand for a full wash, you need a shower chair. In a walk-in shower with no rim, a bench has nothing to span and a chair is the only option.

Can you use a transfer bench with a glass shower door?

No. The door frame runs along the tub rim exactly where the bench needs to cross, so the bench physically cannot sit in place. The usual solution is to remove the doors and fit a shower curtain, which is a bigger and more expensive job than the bench itself — so check for a door before ordering rather than after delivery.

How do you stop water going everywhere with a transfer bench?

Run the shower curtain inside the bench — between the seat and the tub interior — rather than outside it. That way water runs down the curtain into the tub while the outer end of the bench stays dry. A split or second short curtain makes this much easier, and a rubber-backed non-slip mat outside the tub catches whatever escapes. A handheld shower is close to essential, since a fixed overhead head sprays straight past someone on the outer end.

What is a tub bench used for?

A tub bench sits entirely inside a bathtub, wider and usually lower than a shower chair, for someone who can still step over the rim but cannot lower themselves to the tub floor or rise from it. It keeps water inside the tub and works with a glass door, which a transfer bench does not. Its limitation is that it does nothing about the rim — so if crossing that is already getting harder, a transfer bench is the more future-proof purchase.

Does Medicare cover shower chairs or transfer benches?

Original Medicare covers neither. Part B classifies both as comfort or convenience items rather than durable medical equipment, on the basis that someone without an illness or injury could also use one. Medicare Advantage plans frequently do cover them through over-the-counter allowances, and equipment loan closets stock all three heavily because so many people need them only temporarily.

Checklist ✅

The bottom line

One question decides it. Is the difficulty standing up, or getting in? A shower chair answers the first; a transfer bench answers the second; a tub bench sits between them and does nothing about the rim.

Watch one bath before buying and the answer will be obvious within a minute. Then check two things that catch people out after delivery: whether there is a glass door in the way, and whether the tub is actually the right size. And whichever you buy, plan a grab bar with it — all three give somewhere to sit, and none gives anything to hold on the way there.
