Yes, a bedside commode is one of the most important pieces of equipment you can have ready before you come home from hip replacement surgery. It keeps you safe during the highest-risk weeks of recovery, and it makes those late-night bathroom trips much less stressful.
Here is what you need to know about using one safely: the right height, the right features, and the right technique to protect your new hip from day one.

Why You Need a Commode After Hip Surgery
The first 6 to 12 weeks after a total hip replacement are the highest-risk period for dislocation. During that time, your surgeon will give you a set of hip precautions: specific movement limits designed to protect the joint while the surrounding tissue heals. Getting to the bathroom is one of the most common moments those precautions are accidentally broken.
A bedside commode solves two problems at once. It brings the toilet to you when walking to the bathroom feels unsafe at night, and it can also be placed directly over your existing toilet to raise the seat height to a safe level. In our experience, it is one of the first things an occupational therapist will recommend before you leave hospital.
What are hip precautions and why do they matter?
Hip precautions are movement restrictions your surgeon or physio sets based on the approach used for your surgery. The most common restrictions for a posterior approach are:
- Do not bend your hip past 90 degrees
- Do not cross your legs or ankles
- Do not turn your foot inward on the operated side
An anterior approach typically comes with fewer restrictions, but your team will confirm exactly what applies to you. Breaking these limits, even once, can cause the ball of the implant to pop out of the socket. That is a serious complication requiring urgent medical attention. Following precautions consistently is not optional during the early recovery phase.
Why a standard toilet height creates real risk
A standard Australian toilet sits at around 38 to 43 cm from the floor. For most people recovering from hip surgery, that is too low. Sitting down to that height forces your hip to flex well past 90 degrees, which violates the precautions and puts real stress on the new joint.
Your hips need to sit at or above the height of your knees throughout recovery. For most people that means a seat height of around 48 to 55 cm. A height-adjustable bedside commode is the easiest and safest way to achieve this, both at the bedside and over the toilet.
Choosing and Setting Up the Right Commode
Not all commodes are equally suitable after hip surgery. Some are too narrow, too low, or lack the armrests you need to push yourself safely to standing. Getting the right one before surgery makes recovery noticeably smoother.
What height should a commode be set to after hip replacement?
The goal is to keep your hips at or above the level of your knees when you sit. For most people, this means setting the commode to a seat height of around 48 to 55 cm. Your feet should still rest comfortably flat on the floor when seated. Your occupational therapist or physiotherapist will confirm the ideal height for your body, so if you have a pre-surgery OT assessment, bring this question to that appointment.
Most height-adjustable commodes use push-button leg adjustments that are simple to set without tools. Check the minimum and maximum height range before you buy, as some models have a narrower range than others.
Key features to look for
When you are choosing a bedside commode for post-hip-surgery use, these are the features that matter most:
- Height adjustability: The legs should adjust to match your individual height requirement. Look for a range of at least 43 to 58 cm.
- Sturdy armrests: You will be pushing up from the armrests every single time you stand. Fixed or drop-arm armrests that lock firmly in place are essential. Wobbly armrests are a safety risk.
- Wide enough seat: A narrow seat makes hygiene difficult and can feel unstable. Look for a seat width of at least 44 cm.
- Stable base: A wide, four-leg frame with non-slip feet is far safer than a frame with a small footprint.
- 3-in-1 design: A commode that also works as a raised toilet seat frame (placed over the toilet) and as a free-standing chair gives you the most flexibility during recovery.
- Weight capacity: Check that the rated weight capacity comfortably exceeds your own weight. Most standard commodes are rated to around 115 kg; bariatric models are available for higher requirements.

How to Use a Commode Safely After Hip Surgery
Having the right commode is only half of the equation. How you get on and off it matters just as much. The transfer technique below follows standard hip precaution guidance, but always confirm with your treating physio or OT before you go home.
Safe sitting and standing technique
Sitting down:
- Back up slowly until you feel the commode against the back of your legs.
- Extend your operated leg forward slightly, keeping your foot pointing ahead (not inward).
- Reach back and grip both armrests before you lower yourself.
- Lower slowly, leading with your bottom. Keep your operated hip from bending past 90 degrees.
- Do not lean forward as you sit. Keep your back reasonably upright.
Standing up:
- Slide toward the front edge of the seat first.
- Extend your operated leg out in front of you.
- Push up through both armrests simultaneously. Do not pull on a walking frame to stand.
- Once standing, reach for your walker or walking stick before moving.
Never rush. The moments of sitting and standing are where most hip precaution violations happen at home.
How long will you need it?
Most people use a bedside commode or raised toilet aid for 6 to 12 weeks after hip replacement surgery. The exact timeline depends on your surgical approach, your individual progress, and the advice of your treating team. Anterior approach patients often progress faster and may need the raised seat for a shorter period. Posterior approach patients typically follow stricter precautions for longer.
Your physiotherapist will let you know when you can safely return to using a standard-height toilet. Do not make that call on your own, even if you feel well. The healing taking place in the weeks after surgery is not always something you can feel.
When to talk to your OT or physio
If you have a pre-admission appointment before your surgery, ask your occupational therapist to do a home assessment. They can confirm the right seat height for your body, check whether your bathroom layout will allow a commode over the toilet, and identify any other modifications worth making before you come home. This is the single best step you can take to make your recovery safe and stress-free.
If you are unsure which commode to buy, or if you have other conditions that affect your mobility (arthritis, balance issues, or a high BMI), your OT is the right person to advise you. We always recommend speaking with your healthcare team for personalised guidance before making equipment decisions.
Key Takeaways
- A bedside commode is essential after hip replacement surgery to keep your hips safely above knee level when seated.
- Set the seat height so your hips are at or above knee level, typically 48 to 55 cm for most adults.
- Choose a 3-in-1 height-adjustable model with firm armrests and a wide base.
- Use correct sit-to-stand technique every time: extend your operated leg, grip both armrests, and lower slowly.
- Most people need a commode or raised seat for 6 to 12 weeks. Your physio will confirm when you can stop.
- Ask your occupational therapist for a home assessment before surgery to get the setup right from day one.
Finding the Right Commode for Your Recovery
A bedside commode is not a permanent fixture. It is a short-term tool that makes one of the riskiest parts of your recovery safe and manageable. Getting the right model before your surgery, at the correct height with the right armrests, means you can focus on healing rather than worrying about whether each bathroom trip is safe.
We stock a range of height-adjustable commodes suited to hip replacement recovery, including 3-in-1 models that work as both a bedside commode and a raised toilet frame. Browse our bedside commodes collection and find the right fit before your surgery date. Because independence matters, including getting it back as safely and quickly as possible.
