Ambulant toilet requirements
Not the same thing as an accessible toilet, triggered by different rules, and routinely left out of a fitout until the certifier asks.
The short answer
This is the requirement that most often appears late, because it is easy to assume that providing an accessible toilet covers everything. It does not, and the two serve different people.
Key points
- An ambulant cubicle is for people who walk but have difficulty, not for wheelchair users.
- It is a cubicle inside a normal toilet block, not a separate room.
- The trigger is the number of pans you provide, not accessibility on its own.
- Grabrails to both sides, an outward opening door, and a wider cubicle than standard.
- Providing an accessible unisex toilet doesn’t remove the requirement.

What an ambulant cubicle actually is
An ambulant accessible cubicle is a toilet cubicle inside an ordinary toilet block, designed for someone who walks but has difficulty doing so. Somebody using a stick or a frame, someone with limited balance, someone recovering from a hip replacement, an older patient who needs something to push up against.
It’s not a room. It is a cubicle, and it sits within the bank of cubicles you were building anyway.
An accessible unisex sanitary compartment, by contrast, is a separate room sized for wheelchair circulation and transfer. Different user, different requirement, and providing one doesn’t discharge the other.
What makes it different from a standard cubicle
- Wider. The cubicle is dimensioned so grabrails on both side walls fall within reach from the pan.
- Grabrails to both sides. Positioned so someone can push up with both arms, which is the whole point of the cubicle.
- The door opens outward, or slides. An inward-swinging door leaves nowhere to stand and cannot be opened if someone falls against it.
- Door hardware operable without a tight grip or a twisting wrist action, and a means of opening the door from outside in an emergency.
- Clear space in front of the pan for a person and, where needed, a carer.
When it’s triggered
This is the part people get wrong. The trigger is not "do we have an accessible toilet". It’s how many closet pans you are providing.
Under the NCC, where sanitary facilities are provided in a building and there is more than a single pan in a bank, an ambulant accessible cubicle is generally required for each sex. The precise threshold and the exceptions live in the Code and are assessed by your certifier against your specific classification and occupancy.
Which produces two common fitout outcomes:
A small clinic with one unisex accessible toilet and no other pans frequently has no ambulant requirement at all.
A larger practice that builds separate male and female toilets with two or three pans in each is very likely to trigger an ambulant cubicle in both, and that is floor area nobody allowed for.
The design consequence is worth understanding early: adding a second and third pan is not a small decision. It can pull an ambulant cubicle into each block, and cubicles are wider than the standard ones you were drawing.
Where it catches out a clinic fitout
Late discovery. The sanitary provision is calculated at documentation, the ambulant requirement appears, and the toilet block no longer fits the space allocated to it. Something else on the plan has to shrink, and it is usually a consulting room.
Relying on base building facilities. Whether shared facilities in the building can serve your tenancy depends on the building, the classification and the travel distance. It is a certifier's answer, not an assumption.
Inward-opening doors. Cubicle doors are drawn opening inward by habit. An ambulant cubicle cannot have one, and the correction changes the circulation space in front of the bank.
Refurbishments. An existing toilet block built to an older code frequently has no ambulant cubicle, and touching it can bring the requirement into play.
What to do about it
Settle your sanitary provision at concept stage rather than documentation. Count the pans, ask your certifier what that count triggers for your classification, and allow the floor area before the layout hardens around it.
It is a small amount of space and a small amount of money when it’s planned. It’s a redesign when it isn’t.

Questions
What is an ambulant toilet?
An ambulant accessible cubicle is a toilet cubicle within an ordinary toilet block, designed for someone who can walk but has difficulty. It is wider than a standard cubicle, has grabrails to both side walls and a door that opens outward or slides.
What is the difference between an ambulant and an accessible toilet?
An accessible unisex sanitary compartment is a separate room sized for wheelchair circulation and transfer. An ambulant cubicle sits inside a normal toilet block and serves people who walk with difficulty. They serve different users, and providing one does not discharge the requirement for the other.
When is an ambulant cubicle required?
The trigger is the number of closet pans provided rather than accessibility on its own. Under the NCC, where sanitary facilities include more than a single pan in a bank, an ambulant accessible cubicle is generally required for each sex. Your certifier assesses the threshold against your building classification and occupancy.
Does a small clinic need one?
Often not. A small practice providing a single unisex accessible toilet and no other pans frequently has no ambulant requirement. A larger practice building separate male and female toilets with two or three pans in each very likely does, in both.
Why must the door open outward?
An inward-swinging door leaves nowhere to stand inside the cubicle and can’t be opened if someone falls against it. Outward-opening or sliding doors are required, and that changes the circulation space needed in front of the bank of cubicles.
