When it comes to designing or renovating public or commercial washrooms, one of the most important considerations is toilet cubicle dimensions. Getting the size right not only ensures a comfortable and private user experience, but it also helps you meet Australian building codes and accessibility standards.

Whether you’re an architect, builder, or facility manager, understanding the correct toilet dimensions in Australia is key to creating safe, compliant and user-friendly amenities.

In this guide, we’ll walk you through the standard toilet cubicle sizes, important compliance considerations, and practical tips for selecting the right toilet partitions for your project.

Why Do Toilet Dimensions Matter?

While a toilet cubicle may seem like a simple space, its design significantly affects functionality, accessibility, and hygiene.

Getting the toilet dims right ensures:

• User comfort and privacy
• Compliance with Australian Standards (AS 1428.1 and NCC)
• Accessibility for people with disabilities
• Efficient use of space
• Ease of maintenance

Incorrect dimensions can lead to costly alterations later down the line and potentially expose building managers to legal or safety risks.

Standard Toilet Dimensions in Australia

The recommended size of a toilet cubicle depends on the type of facility and the intended users. Below are the typical toilet dimensions in Australia based on current guidelines.

🚻 Standard Cubicles

For general-use toilet cubicles (non-accessible):

• Width: 900mm – 1000mm
• Depth: 1500mm – 1800mm
• Door Width: 600mm (opening inward or outward depending on layout)
• Partition Height: Usually between 1800mm – 2000mm from floor level
• Clearance: Minimum 20mm clearance from the floor

These dimensions provide enough space for comfort and movement, while still being space-efficient.

♿ Accessible Toilet Cubicles

To comply with AS 1428.1 (Design for Access and Mobility), accessible cubicles must provide additional space for wheelchairs and carers.

Recommended Accessible Toilet Dimensions:

• Width: Minimum 1900mm
• Depth: Minimum 2300mm
• Door Width: Minimum 850mm (swing-out or sliding preferred)
• Turning Circle: 1540mm diameter (minimum clear space for wheelchair turning)
• Grab Rails: Installed on adjacent walls at 800–810mm height
• Toilet Pan Location: Offset 450–460mm from the adjacent side wall

Accessible cubicles should also feature contrasting colours between partitions and walls for visibility, and a lock that’s operable with one hand.

🚼 Ambulant Cubicles

Ambulant toilet cubicles cater to people with limited mobility but who don’t require a wheelchair.

Ambulant Cubicle Dimensions:

• Width: 900mm – 920mm
• Depth: 1600mm – 1800mm
• Grab Rails: Both sides of the cubicle, 800mm – 810mm above floor level
• Door Width: Minimum 700mm

Ambulant cubicles must be clearly signed and are often located next to standard or accessible cubicles.

Compliance & Building Code Considerations

The National Construction Code (NCC) and the Australian Standards (especially AS 1428.1) outline the legal requirements for toilet partitions and cubicles in commercial and public buildings.

Key requirements include:

• Minimum numbers of accessible and ambulant cubicles per gender based on total cubicles
  
• Sufficient circulation space for wheelchair users
  
• Durable, non-slip flooring and hygienic materials
  
• Clear signage for accessible and ambulant facilities
  

Working with an expert like Cubispec ensures your washroom design aligns with every detail of these codes—while still delivering a stylish, cohesive aesthetic.
