Construction toilet requirements cannot be reduced to one unit per 20 workers. Project value, workforce, site layout and access affect the facilities needed. This guide helps you prepare a hire enquiry; the principal contractor must assess the project's requirements.
What changed in Queensland?
Queensland's construction amenities changes took effect on 1 January 2025. They introduce requirements for designated female toilets on specified projects. Smaller projects still have duties to provide adequate facilities.
Schedule 5A of Queensland's Work Health and Safety Regulation distinguishes small projects, costing less than $7.5 million, from large projects. Its example for a small project with 20 construction persons requires at least two toilets plus one additional designated female toilet. This is a minimum-count example, not a complete assessment of the facilities needed. Multilevel developments also have location requirements.
A lockable unisex unit is not automatically a designated female toilet. Relevant requirements include restricted use, identification and sanitary amenities. Check Schedule 5A of the current regulation for the applicable categories, thresholds and facilities. The regulation was checked for this revision on 23 October 2026.
What information should the site team gather?
Record the project value and workforce expected during the busiest stage. Include visitors who need amenities, the number of building levels and the distance between work areas and facilities. Identify any existing toilets that will actually be available throughout the job.
Have the responsible site team decide what facilities are needed before ordering. A minimum legal count does not necessarily avoid queues or provide reasonable access across a large site.
Choosing a toilet for the location
A standard construction toilet holds waste for pump-out and needs no sewer connection. Our construction hire includes fortnightly servicing and has a 28-day minimum. Higher use may require extra paid visits.
A sewer-connect toilet needs suitable water and sewer connections arranged with your plumber. It avoids routine holding-tank pump-outs, but cleaning and restocking remain necessary. Neither option alone establishes compliance.
Plan access before delivery
Give the supplier a site plan and photos of the proposed position. Keep a safe route for users and access for the delivery and service vehicles. Consider how fencing, excavation and stored materials will change that access during the build.
For upper floors, the site team must plan safe lifting and future service access. Do not assume a crane-liftable toilet can be put anywhere without reviewing the lift and location.
Keep amenities usable through the build
Nominate who checks cleanliness and supplies between visits. Review the service schedule when more trades arrive. Report faults or rising usage before a toilet becomes unusable, and keep records of agreed service visits.
Include hand-washing facilities with water and soap in the amenities plan. Check privacy, door locks and lighting, and provide suitable sanitary-waste bins. Sanitary products must not be flushed into a portable toilet. Keep the unit stable and the approach clear as site conditions change.
For hire options and current minimum prices, use the portable toilet hire page. Send the site address, dates and the assessed unit requirements with your enquiry.
