If you or someone you care for weighs more than a standard commode or shower chair is built for, look at two numbers first: the weight capacity on the label and the seat width. The bariatric commodes in our store are rated from 650 lb up to 1,000 lb. For bathing, our heavy-duty shower chairs and tub transfer benches are rated to 500 lb, and a rolling bariatric shower commode chair goes up to 1,000 lb. Pick a model rated comfortably above the user's weight, make sure the seat is wide enough, and check that it fits the bathroom before you order. You can browse everything in one place in our bariatric medical equipment collection.

Why weight capacity and seat width both matter

Weight capacity tells you how much the frame is rated to hold. Seat width tells you whether the person can sit comfortably without the arms pressing on their hips. A chair can have plenty of capacity and still feel cramped, so check both.

  • Leave some margin. Choose a product rated above the user's current weight rather than right at it. Getting on and off a seat puts extra force on the frame.
  • Measure the hips while seated. Measure across the widest part of the hips while the person sits, then add a little room for clothing and comfort.
  • Think about transfers. If the person slides sideways from a bed or wheelchair, drop arms make that much easier for both the user and the caregiver.

Bariatric commodes: 650 lb vs. 1,000 lb

650 lb folding commode

The Dynarex Bari+Max Folding Commode is a 3-in-1 design: it works as a bedside commode, a raised toilet seat, or a safety frame over an existing toilet. It sets up without tools, comes with a bucket and cover, and folds flat when not in use. This is a good choice when the user can stand and pivot to sit down, and when storage space is tight.

1,000 lb drop-arm commode

The Bari+Max HD Drop Arm Commode is made of powder-coated steel, is height-adjustable, and comes in 26" and 30" sizes. Its easy-release arms drop down so the user can slide on from the side instead of standing up and turning. Caregivers often prefer drop arms because they reduce lifting and twisting during transfers. It includes a commode bucket with cover and sets up without tools.

Bariatric shower seating: chairs, benches and rolling commodes

Shower chair with back (500 lb)

The Adjustable Bariatric Shower Chair with Back has an aluminum frame, a plastic seat with drainage holes, hand grips, and non-slip rubber tips. The seat height adjusts in 1-inch steps from 16" to 20", and the back can be removed. It suits users who can walk into the shower and want back support while seated.

Mobile shower commode chair (1,000 lb)

If getting into the shower is the hard part, a rolling chair can help. The Bari+Max HD Mobile Shower Commode Chair is rated to 1,000 lb, has a steel frame and wheels, and has drop arms for side transfers. A slide-in bucket with cover lets it double as a bedside or over-toilet commode. It comes in 26" x 20" and 28" x 20" seat sizes. Rolling chairs work best with a roll-in or curbless shower, since wheels cannot cross a tub wall.

Bathroom fit checklist before you order

Bariatric equipment is larger than standard equipment, so measure the space first:

  1. Doorway width: Measure the bathroom door opening. A rolling shower commode must fit through it.
  2. Shower entry: Is there a curb or tub wall? Wheels need a level, curbless entry.
  3. Floor space inside the shower: Compare the chair's footprint with the shower floor, and leave room for a caregiver to help.
  4. Toilet clearance: If using a commode over the toilet, measure the space between the toilet and the nearest wall or vanity on each side.
  5. Seat height: With the user seated, feet should rest flat on the floor with knees at about hip level.
  6. Who helps with transfers: If a caregiver assists with side transfers, choose drop arms.
  7. Storage: If space is limited, a folding commode is easier to put away.

Safety tips for everyday use

  • Set the height and check that every leg is locked at the same setting before first use.
  • Lock the wheels on a rolling chair before anyone sits down or stands up.
  • Empty and clean the bucket after each use, and check that it slides back fully into place.
  • Look over the frame, rubber tips and fasteners regularly, and stop using any part that is bent, cracked or loose.
  • Pair your seat with grab bars near the toilet and shower for extra support.

Frequently asked questions

What weight capacity should I choose?

Choose a product rated above the user's current weight, not right at it. Sitting down and standing up put extra force on the frame. If the user is close to 650 lb, a 1,000 lb model gives more margin.

Can a bariatric commode be used over a regular toilet?

Many can. The Dynarex Bari+Max Folding Commode is listed as 3-in-1, meaning it can be used as a bedside commode, a raised toilet seat or a toilet safety frame. The Mobile Shower Commode Chair can also roll over a toilet. Measure the space around your toilet first.

Are drop arms worth it?

If the user moves from a bed or wheelchair by sliding sideways, or if a caregiver helps with transfers, drop arms make the move simpler. If the user can stand and turn on their own, fixed arms may be fine.

Can a rolling shower chair go in a bathtub?

No. Rolling shower chairs are made for roll-in or curbless showers. For a tub, a seated shower chair or a tub transfer bench is usually the better fit. Measure the tub's wall height and inside width before choosing one.
