Setting Up Your Bedside Commode

Most bedside commodes arrive partially assembled and only need a few minutes to put together. Work on a flat, stable surface such as a carpeted bedroom floor so the commode does not slide while you are adjusting it.
Assemble the frame
- Remove all parts from the packaging and lay them out: the main frame (two side rails), the seat, the lid, the bucket and (on some models) removable armrests or a drop-down arm.
- Slide the two side rails together until the locking pins click securely into place. On most steel-frame commodes, a brass or chrome push-button locks each joint. Check each one by hand before continuing.
- Attach the armrests if they are separate components. They typically drop into slots on the side rails and secure with a pin or bolt. On drop-arm models, make sure both hinges are fully engaged before applying weight.
If any joint feels loose or a button does not click, stop and check the manual for your specific model. Never use a commode with unsecured joints.
Adjust the leg height to suit the user
The correct seat height for a commode is the same as the user's knee height when they are standing upright. At this height, their feet rest flat on the floor when seated, hips are at or slightly above knee level, and standing up is far easier and safer.
- Have the user stand beside the commode (or measure their knee height while seated in a standard chair, from the back of the knee to the floor).
- Press the push-pin button on each leg inward and slide the lower leg section up or down until the leg reaches the correct notch.
- Release the button and check that it has fully engaged in the hole. Give the leg a gentle tug to confirm it is locked.
- Repeat for all four legs, making sure every leg is set to the same notch so the commode sits level.
If you are not confident about the right height, an occupational therapist can assess the user and recommend the safest setting. Most local aged care services can arrange a home visit for this.
Install the bucket, seat and lid
- Lower the waste bucket into the frame opening until it sits flush and does not rock.
- Place a small amount of water in the bucket (roughly 2 cm). This reduces odour and makes cleaning easier.
- If you are using a commode liner, drop it into the bucket now and fold the edge over the rim to keep it in place.
- Align the seat over the frame and press it down until it sits flat. Most seats have rear plastic clips that hook over the back rail.
- Attach the lid on top of the seat in the same way.
Lift and press down on the seat firmly before the first use to confirm it is not shifting. A properly installed seat will not move side to side.
Positioning the Commode in the Room

Where you place the commode matters as much as how you assemble it. A well-positioned commode reduces the risk of a fall and makes transfers from the bed as safe and dignified as possible.
How far from the bed should a commode sit
Position the commode within one step of the bed, on the user's stronger side if they have one. The ideal placement lets the user pivot from the edge of the mattress directly onto the commode seat without needing to walk or turn more than 90 degrees.
Make sure there is clear floor space on both sides of the commode. This gives you or another carer room to assist if needed. Remove any rugs or cables in the path between the bed and the commode.
Checking stability before first use
Before the commode is used for the first time, do a quick stability check:
- Place both hands on the armrests and press downward firmly. The frame should not flex or creak.
- Rock the commode gently from side to side. All four legs should remain in contact with the floor. If one leg lifts, re-check that all legs are at the same height setting.
- Sit on the commode yourself (if able) or place a weight equal to the user's body weight on the seat for a few seconds to check for any movement.
On hard floors such as tiles or floorboards, add rubber leg caps or a non-slip mat under the commode to prevent it from sliding during transfers.
Key takeaways
- Correct seat height equals the user's knee height standing: feet flat on the floor, hips at or slightly above knee level.
- Check every push-pin button locks before use. Loose legs are the most common cause of commode instability.
- Position the commode within one step of the bed on the user's stronger side, with clear floor space on both sides.
- Add a small amount of water to the bucket before first use to make cleaning easier and reduce odour.
- On hard floors, use rubber leg caps or a non-slip mat to prevent sliding during transfers.
