A grab rail installed in the wrong position can give a false sense of security while doing very little to prevent a fall. The height, the angle, and the location all affect whether the rail actually supports you when you need it. This guide covers the correct positions for every grab rail in the bathroom, so you can buy with confidence and fit them where they count.
Key takeaways
- Toilet grab rail: 150 to 200mm from the side of the toilet bowl, top of rail at 820 to 840mm from floor level
- Shower horizontal rail: 900mm from floor for lateral movement; angled rail at the entry for getting in and out
- Bath rail: vertical at the tub rim for lowering in, horizontal at 600mm from the bath floor for getting up
- Rails must be fixed to wall studs or rated anchors, not plasterboard
- Australian Standard AS 1428.1 provides load and height guidance that is excellent practice for home use

Toilet Grab Rail Position
The toilet is one of the highest-risk spots in the bathroom. Sitting down and standing up require balance and leg strength, and both decline with age. A grab rail beside the toilet gives you a fixed point to push up from and lower down with confidence.
The correct side and height
The standard position for a toilet grab rail is 150 to 200mm to the side of the toilet bowl (measured from the toilet centre to the rail centre). The top of the rail should sit at 820 to 840mm above the finished floor level. This places the rail at a natural gripping height when you are seated, and allows you to push down through the rail as you stand.
If possible, install rails on both sides of the toilet. This accommodates people with weakness on either side and is particularly helpful for anyone managing stroke recovery, Parkinson’s, or one-sided weakness. A fold-down rail on the open side is a practical option where space is limited.
What the Australian Standard recommends
Australian Standard AS 1428.1 was designed for public buildings, but its height and load requirements are the best available guidance for home installation too. The key requirement: rails must be capable of sustaining a point-load of at least 1.1 kN (roughly 110 kg). That means fixing to wall studs or using structural anchors rated for that load, not standard plasterboard anchors.
When asking a builder or plumber to install rails, the phrase “fixed to AS 1428 load requirements” will get you the right standard of installation.
Shower Grab Rail Position
The shower requires at least two rails: one for lateral stability while you are inside, and one at the entry for getting in and out. These serve different functions and are positioned differently.
Horizontal rail for lateral support
Inside the shower, a horizontal rail on the side wall at approximately 900mm from the floor gives you a stable grip while you wash and turn. This rail supports lateral movement and steadies you while standing. It should run at least 400mm in length, and 600mm is better if the wall allows.
Angled or vertical rail at the shower entry
At the shower entry, a 45-degree angled rail or a vertical rail gives you a point to hold while stepping in and out. This is the highest-risk moment in the shower. A 45-degree rail is particularly useful because it provides support for a range of hand positions, from a lower grip while stepping in to a higher grip when straightening up. Position it at the entry edge, within easy reach as you step over any threshold.
Bath and Entry Grab Rail Positions
Getting in and out of a bath is more physically demanding than using a shower, and the correct rail placement is essential for anyone who still prefers to bathe.
Bath grab rail placement
Two rails are recommended for anyone using a bathtub:
- A vertical rail at the side of the tub, near the tap end, for lowering yourself in and pushing up when exiting. Position it so you can grip it at shoulder height when seated.
- A horizontal rail on the long wall of the bath at approximately 600mm above the bath floor. This gives you something to push against when rising from a lying position.
A non-slip mat inside the bath is essential alongside these rails. Read our guide on the best non-slip bath mats for elderly Australians for what to look for.
Entry and hallway grab rails
A grab rail near the bathroom doorway is often overlooked but valuable for anyone who is unsteady on their feet. A doorstep, a narrow entry, or a slippery floor in the hallway outside the bathroom all create risk. A short vertical rail fixed at the door frame, positioned at 900 to 1000mm from the floor, gives you a point to steady yourself before and after the bathroom visit.
