Bariatric Shower Chair: 500 to 700 lb Picks and Seat Widths
Four bariatric shower chairs and a transfer bench rated 500 to 700 lb, with seat widths, height ranges, printed sizes and prices, and what to measure first.
You sit down on a shower chair and the seat ends before your hips do, or you feel the legs flex as you lower yourself onto it. Buying by the word bariatric does not settle it: two picks below share a 20 by 12 inch seat while one is rated to 550 lb and the other to 700. Below are four shower chairs and one transfer bench whose pages print a rating, a seat or between-arms width and a height, with who each one suits and what to measure before ordering.
The short answer

| Vive 4-in-1 Bariatric Commode Shower Chair | A wider seat with arms | $99.99 | 550 lb, 23 in seat (infographic), arms and back detach |

What the rating does not tell you
A rating says what the frame carries; the seat size says whether you fit on it (our reading). The Big John and the Vive stool make the point: both print a 20 by 12 inch seat, and the ratings are 700 and 550 lb (550 in the Vive’s text; one image shows 500). Across the four picks that print a seat size, widths run from 20 inches to 26½ (20 as the Big John’s width is our reading of its flyer photo; its page prints 20 x 12 unlabelled), and the fifth, the IPU, gives 28 inches between its arms instead.
Heights and sizes are worded differently from page to page, so the table keeps each page’s own label.
| Pick | Rated to | Seat (page’s label) | Height (page’s label) | Back / arms | Size printed (page’s label) | Frame |
|---|---|---|---|---|---|---|
| Big John | 700 lb | Seat 20 x 12 in | Adjustable Height 17–21 in | Back, no arms (flyer photo) | Width 20 in, Depth 18.75 in | Aluminum |
| Vive 4-in-1 | 550 lb | Extra-wide seat 23 in (infographic); Seat W x L 58.5 x 46.5, no unit (list) | Seat Height 46–56 cm (list); 18–22 in, unlabelled (drawing) | Detachable back and arms | None in spec list | Aluminum |
| Drive transfer bench | 500 lb | Seat Dimensions 26.5 (W) x 16.5 (D) in (catalog) | Seat Height 18.5–23.5 in | Back and one arm rail | Product Dimensions 32.5 in L x 24 in x 30 in H | Aluminum |
| Vive stool | 550 lb (text); 500 on one image | Seat 20 x 12 in; Wide 20” Seat (image) | Height range 16–21 in (text); Height 15–20 in (dimensions) | No back | Legs (floorspace used) 16 x 16 in | Anodized aluminum |
| IPU BSC660 | 700 lb | Between the Arms 28 in | Seat Height 21.25 in (page); 21.5 in (datasheet) | Soft backrest, arms | Width 31.75 in, Depth 29.5 in | Not named |
Stool, chair, transfer bench or rolling chair
Which of four shapes you need depends on how you get into the shower (our reading). A stool, like the Vive stool, has no back, and it is the only pick whose page prints the floor its legs take, 16 by 16 inches, for a tight stall. A chair adds a back and sometimes arms: the Big John has a back, and the Vive 4-in-1 has both, which detach. A transfer bench is longer than either; the Drive is 32.5 inches, enough to sit down outside the tub and move across instead of stepping over the wall (again our reading). A rolling chair like the IPU is for a curbless shower you can wheel straight into (our reading).
The five picks
Big John Heavy Duty Shower Chair (BJBATH)
One of two picks rated to 700 lb, at about an eighth of the other’s price (our arithmetic, against the IPU at ALCO). The page lists a 700 pound capacity, a seat with drainage holes, a corrosion proof aluminum frame and cross-leg support; the height adjusts in 1 inch steps. The page lists Width 20 inches and Depth 18¾, figures to check against the floor of your tub. The maker’s flyer shows it with a backrest and no arms. Pick it if you need 700 lb in an ordinary tub and your hips fit a 20 inch seat (20 as the width is our reading of the flyer photo).
Drawbacks: The seat is the same 20 by 12 inches as the 550 lb Vive stool, so if your seated hips measure close to 20 inches, the extra rating does not buy you room. The page and flyer call 17 to 21 inches adjustable height and do not say where it is measured to; total height is 30 to 34 inches.
Vive 4-in-1 Bariatric Commode Shower Chair
The lowest quoted price of the five picks on a chair with arms and a seat wider than 20 inches. The infographic calls the seat 23 inches; the spec list gives Seat W x L as 58.5 x 46.5 with no unit on that line, while the backrest, seat-height and bucket lines beside it are in centimetres; read as centimetres, 58.5 x 46.5 is about 23 by 18.3 inches (our arithmetic). Seat height runs 46 to 56 cm on the list; the drawing shows 18 to 22 inches beside a vertical arrow, without a label. The backrest and armrests both detach. It doubles as a bedside commode, with a removable bucket. The frame is aluminum and weighs 12.8 lb.
Drawbacks: The seat has a commode opening in the middle, and the spec list prints no width for the chair as a whole; the widest figure on its dimension drawing, 25.8 inches, carries no label, so ask Vive for the leg-to-leg width before ordering for a tub.
Drive Medical Bariatric Transfer Bench (12025KD-1)
The bench for a tub you would rather not step over, and the widest printed seat width of the five picks (the IPU gives a between-arms figure instead): 26.5 inches wide and 16.5 deep on Drive’s trade catalog page for the same item number. Drive’s own store lists 500 lb, a 32.5 inch length and a seat height of 18.5 to 23.5 inches, with legs that adjust in half-inch steps and suction cups on two of them. The back and the arm rail come off without tools (the photos show one arm, at one end; the store’s feature list says arms), and the bench is reversible, which Drive says accommodates any bathroom. Aluminum frame, blow-molded plastic seat.
Drawbacks: Rated to 500 lb, the lowest rating in any pick's text (the Vive stool's image icon also reads 500). At 32.5 inches long it takes floor outside the tub as well as inside (our reading); the 24 inch figure printed beside that length has no label.
Vive Bariatric Shower Chair
A backless stool; the Uses line on its page calls it a chair with no back. It is the only pick whose page prints the floor its legs take, 16 by 16 inches, which makes it the one to measure against a narrow stall. The page gives the height two ways: 16 to 21 inches in its feature text and FAQ, and 15 to 20 in its dimensions list, and its images show both. The frame is rust-free anodized aluminum and weighs 7 lb.
Drawbacks: No back, and its photos show no arms. The text says 550 lb throughout, but one image shows a weight icon reading 500 beside the words up to 550lbs; plan on 500 (our reading).
IPU BSC660 Bariatric Shower Chair
The pick if you need 700 lb and more width than a 20 inch seat: 28 inches between the arms, a soft backrest, slide-out footrests and push handles, on six locking 5 inch casters. IPU’s page gives the seat height as 21.25 inches and the overall height as 44; its datasheet gives 21.5 for seat height and 42 for height. IPU’s page carries no price. ALCO Sales & Service listed it as AL-56580 at $944 on 30 September 2026; that it is the same chair is our reading, from the IPU brand line and dimensions that match IPU’s page.
Drawbacks: Width 31.75 inches and Depth 29.5 on its page, on casters, so it needs a curbless shower and a doorway to match (our reading). IPU's page and datasheet do not name the frame material, only no-rust casters. The seat is flat polyethylene with a toilet opening.
How to choose: four numbers you can measure
- Your weight, against the rating. If you weigh 500 lb or less, all five picks’ printed ratings cover that. Between 500 and 550, the Vive 4-in-1, Big John and IPU do (the Vive stool’s page also shows a 500 icon). Above 550, only the Big John and the IPU.
- Seated hip width, against seat width. Sit on a hard, flat surface and measure straight across the widest part of your hips, the same way our bariatric chair guide does for armchairs. Under 20 inches with room: the Big John or the Vive stool, both printed as 20 by 12. Up to 23: the Vive 4-in-1. Wider: the Drive bench’s 26½ inch seat or the IPU’s 28 inches between the arms.
- The floor you have, against the size each page prints. Measure the flat part of the tub floor or shower pan. The Vive stool’s legs use 16 by 16 inches; the Big John’s page lists Width 20 and Depth 18¾; the Drive bench is 32.5 inches L and reaches over the tub wall (our reading); the IPU’s page lists Width 31.75 and Depth 29.5, on casters.
- Floor to the back of your knee, against the height each page prints. Sit with your feet flat and measure to the crease behind your knee, then pick a range that includes your number: from 15 inches (16 by its feature text) at the bottom of the Vive stool’s range to 23.5 at the top of the Drive bench’s seat height.
Before you order
- Read the rating on the page you buy from. Where one page prints two figures, as the Vive stool’s does, plan on the lower one (our reading).
- Check the curtain closes. A transfer bench sits across the tub edge, so the curtain has to close over or around it (our reading); our extra wide shower curtain guide lists the widths sold.
- Measure the doorway for anything on casters. The IPU is 31.75 inches wide.
More bathroom and bedroom guides are in the home and bedroom section.
Where these numbers come from
Ratings, dimensions and prices are from the maker pages, images and PDFs linked on each pick, and the IPU price from ALCO Sales & Service, all read on 30 September 2026; the Vive price on 1 October 2026. Where a page printed two figures, both are given above. Centimetre readings and the price comparison are our arithmetic.
Frequently asked questions
What is the weight limit on a bariatric shower chair?
It depends on the model; bariatric is not one number. The five picks in this guide are rated, in their text, from 500 lb (the Drive transfer bench) to 700 lb (the Big John and the IPU BSC660), with both Vive chairs at 550 in their text. Where one page shows two figures, as the Vive stool's does (550 in its text, 500 on one image), plan on the lower one (our reading).
How wide is a bariatric shower chair seat?
Of the five picks, four print a seat size: 20 by 12 inches on the Big John and the Vive stool (the Vive stool's image calls the 20 its width; on the Big John, 20 as the width is our reading of the flyer photo), 23 wide on the Vive 4-in-1 (its infographic's figure) and 26.5 wide on the Drive transfer bench. The IPU BSC660 gives 28 inches between the arms instead. Measure your seated hip width and choose a seat wider than that number.
Should I get a bariatric shower chair or a bariatric shower bench?
A chair stands wholly inside the tub or stall; a transfer bench is long enough to reach over the tub wall, so you sit down outside the tub and move across (our reading of the design). The Drive bench here has the widest printed seat width of the five picks, 26.5 by 16.5 inches (the IPU gives 28 inches between its arms instead), but its 500 lb is the lowest rating in any pick's text (the Vive stool's image icon also reads 500).
Will a bariatric shower chair fit in my bathtub?
Measure the flat part of the tub floor and compare it with the listing. The Vive stool's legs take 16 by 16 inches of floor; the Big John's page lists Width 20 inches and Depth 18¾. The IPU BSC660 (Width 31.75 inches on its page) rolls on casters, so it suits a curbless shower rather than a tub (our reading).
