Portable toilets serve a purpose, but standard units don’t always meet accessibility requirements. Without the right features in place, you risk safety issues, failed compliance checks and excluding members of your workforce or community.
Across public events, construction sites, government projects and shared spaces, disabled accessible toilets are a legal requirement under AS1428 and the National Construction Code. More importantly, they allow people to use facilities safely, comfortably and with dignity.
At Instant Toilets & Showers, we supply fully compliant accessible toilets for hire across Western Australia and for sale nationwide. This guide outlines what’s required, when it’s needed and how to choose the right solution for your site.
What is an Accessible Toilet?
An accessible toilet is a purpose-built sanitation facility designed to meet Australian accessibility standards, including AS1428.1, ensuring safe and practical use for people with mobility limitations.
Unlike standard portable toilets, accessible units are engineered with specific dimensions, circulation space and support features that allow wheelchair users and individuals with reduced mobility to enter, manoeuvre and use the facility independently or with assistance.
The key difference between a standard portable toilet and a disabled accessible toilet comes down to layout, circulation space and support features. A compliant accessible unit includes:
- Full wheelchair turning space, typically allowing a 360-degree circulation area, so users can move freely without obstruction
- Wider doorways (generally 900mm or more clear opening) for comfortable entry and exit
- Step-free or ramped access to ensure safe entry without raised thresholds
- Fixtures positioned at compliant heights, including the basin and toilet pan
Transfer zones are another critical requirement. Accessible toilets provide:
- Clear side and rear transfer space beside the pan to allow safe movement from a wheelchair onto the seat
- Grab rails installed to AS1428 specifications, positioned to provide stability during transfer and standing
Understanding AS1428.1 and NCC Compliance
What Is AS1428.1:2021?
AS1428.1:2021 is the Australian Standard for Design for Access and Mobility. It sets out the minimum technical requirements to ensure buildings and facilities can be safely used by people with disabilities.
For sanitation facilities, this includes precise measurements, layout rules and fixture positioning to ensure users can enter, manoeuvre and transfer safely.
How It Links to the National Construction Code (NCC)
The NCC references AS1428 as the benchmark for accessible design. Compliance with AS1428.1 helps ensure facilities meet:
- The NCC requirements for accessible buildings
- The Disability (Access to Premises — Buildings) Standards
- Legal obligations for public events, workplaces and community infrastructure
Failing to meet these standards can expose event organisers, site managers and project owners to compliance breaches and potential penalties.
Key AS1428 Compliance Requirements for Accessible Toilets
A compliant accessible toilet must meet strict criteria, including:
- Circulation space: Adequate internal room to allow a full wheelchair turning circle
- Door width: Generally a minimum 900mm clear opening
- Transfer zones: Clear side and rear space beside the pan
- Grab rail specifications: Installed at precise heights, diameters and positions
- Basin height and clearance: Positioned for seated access
- Ramp gradients: Step-free entry or compliant ramp systems
- Non-slip flooring: To reduce fall risk
- Braille and tactile signage: To assist users with vision impairments
- Continuous accessible path of travel: Clear, step-free access from the main site or event area to the unit
We ensure these elements are built into our accessible range so your site is not only functional, but aligned with Australian standards from the outset. This reduces compliance risk and gives organisers, site managers and councils confidence that accessibility has been properly addressed.
For a detailed breakdown of how our units meet and exceed these requirements, see our guide on How Our Portable Sanitation Products Comply with AS1428.
When Are Disabled Accessible Toilets Required?
Public Events
For public events, accessible toilets are a legal requirement under Australian accessibility standards.
This applies to:
- Festivals and concerts
- Sporting events
- Community markets and council activations
- Corporate functions open to the public
- School and university events
Accessible units must:
- Be provided in addition to the required number of standard toilets
- Be positioned along a continuous accessible path of travel
- Be clearly signposted and easy to locate
- Not be isolated or treated as an afterthought
When mapping out site layouts, permits and risk assessments, sanitation planning needs to include compliant accessible units from day one.
If you are planning an event in WA, our Event Planning Checklist for WA Events provides a structured timeline that includes accessibility, sanitation placement and compliance considerations.
When calculating quantities, accessible units must also be factored into your overall numbers. Our guide on How Many Portable Toilets Per Person explains ratio planning for events and how to size amenities correctly.
Construction & Industrial Sites
On construction and industrial sites, providing accessible sanitation is tied directly to workplace safety legislation.
Under WHS regulations, employers must:
- Provide adequate and hygienic toilet facilities
- Ensure facilities are accessible to all workers
- Maintain safe access to amenities
- Prevent health risks through proper servicing and placement
Failing to provide suitable amenities can expose site managers to compliance breaches and reputational damage.
Beyond legal requirements, accessible toilets support:
- Worker dignity
- Inclusive hiring practices
- Safe use for employees with temporary or permanent mobility limitations
Our article on The Importance of Sanitation on Work Sites outlines the broader health, legal and productivity impacts of proper facility planning.
Councils & Government Projects
Local councils and government departments operate under heightened compliance scrutiny.
Accessible toilets are required for:
- Public infrastructure upgrades
- Community events
- Emergency response deployments
- Seasonal facilities and pop-up services
- Remote or regional works
In these environments, accessibility forms part of:
- Disability access compliance
- Risk management frameworks
- ESG and community inclusion commitments
- Public accountability standards
Providing compliant accessible toilets demonstrates due diligence and reinforces a commitment to inclusive infrastructure.
What Makes a Truly Compliant Accessible Toilet?
Not every larger portable toilet qualifies as compliant. A truly accessible unit must meet strict dimensional, safety and usability standards.
A compliant accessible toilet should include:
- 900mm+ door clearance to allow safe and comfortable wheelchair entry
- Clear side transfer space beside the pan to allow safe wheelchair transfer
- Rear grab rail and side grab rails, installed to specification for stability and support
- Raised toilet pan height to assist with seated transfer
- Lever tapware and accessible controls, operable with minimal force
- Anti-slip flooring, reducing fall risk in wet conditions
- Adequate internal lighting, ensuring safe visibility at all times
- Step-free access or compliant ramp systems, where elevation exists
- Braille and tactile signage, supporting users with vision impairments
When calculating quantities, accessible units must also be factored into your overall numbers. Our guide on How Many Portable Toilets Per Person explains ratio planning for events and how to size amenities correctly.

Do I legally need an accessible toilet at my event?
Yes. Public events in Australia are required to provide accessible toilet facilities that meet AS1428 standards and the National Construction Code. Accessible units must be included in addition to the required number of standard toilets and positioned along a continuous accessible path of travel.
If your event is open to the public, accessible facilities should be factored into your planning from the outset.
How many accessible toilets are required?
The number of accessible toilets required depends on a multitude of factors. Accessible units must be included within your overall toilet count and cannot replace standard units.
As a general guide, at least one compliant accessible toilet should be provided at public events, with additional units required for larger crowds. Construction sites must also provide adequate accessible facilities where required under WHS regulations.
