Yes. Public toilets, showers, change facilities and small amenity blocks are some of the best buildings to make as modules, because they are mostly wet areas and fixtures that are easier to finish under cover. The modules arrive tiled, plumbed and wired, and are connected to footings and services on site.
The buyers are councils, parks agencies, schools, holiday parks and the builders working for them, from coastal foreshores to regional rest stops. The problem with a traditional build is the number of trades for a small building, often in a remote spot, and a park or school that has to stay open around the work.
Why modular fits amenity blocks
A toilet block is small but trade-heavy: plumbing, drainage, tiling, waterproofing, electrical, ventilation and hardware. In the factory those trades work in sequence with quality checks before anything leaves. On site, the builder only needs footings, sewer, water and power ready.
Government already buys this way. The WA Department of Education runs modular kindy, pre-primary and toilet block programs each school year, and the 2026 mid-year round was awarded on 9 Sep 2026. Our page on WA modular schools covers that pipeline.

We supply to your builder, who carries the head contract and the site. The supply price is quoted for your site.
What does not fit
Sites with no truck or crane access, such as walking-track trailheads, may need a different solution. Very small single toilets can be cheaper as a precast unit. Where a heritage overlay sets strict materials, a conventional build may be simpler to approve.
The approval path
Public amenities generally need a building permit or approval, and planning approval depends on the zone and land owner. EcoPrestige coordinates the module design with your consultants; permit drawings are issued by the registered or licensed practitioner the state requires. In Queensland, permit drawings are issued under a QBCC licensed building designer. In Tasmania, permit drawings are issued by a licensed Tasmanian building designer. A building surveyor or certifier certifies and confirms the NCC class. Confirm with your building surveyor or certifier.
Our page on the building permit for modular buildings sets out the inspections.
The programme
While the modules are in the factory, the builder removes the old block and brings sewer, water and power to the pad. Factory and site work run in parallel, so the public area is closed for a shorter time. Installation is usually a crane lift and connection, then the surveyor’s final inspection.
Design points to settle early
- How many rooms of each type, and whether any are unisex or all-gender.
- Accessible toilet and, where needed, accessible adult change facilities.
- Opening hours, lighting and whether the block is locked at night.
- Ventilation, drainage falls and wash-down needs for cleaning crews.
- Hand basin, fixture and tapware types that the owner can maintain.
Getting these into the brief before production avoids changes once the modules are built.
Where these are used
Councils use them on foreshores, sports grounds and rest areas; see our guide for regional councils. Holiday parks use them as shower blocks; see our page on holiday park cabins. Industrial sites use them beside warehouses; see industrial ancillary buildings.
What to send us
- 1. The site address and photos of the existing block, if any.
- 2. The number and type of rooms needed.
- 3. Expected users and peak times.
- 4. Sewer, water and power availability at the site.
- 5. Crane and truck access notes.
Modular toilet blocks: FAQ
Can a toilet block arrive fully plumbed?
Yes. Fixtures, pipework, tiling and waterproofing are done in the factory. The builder connects sewer, water and power on site.
Do schools buy modular toilet blocks?
Yes. The WA Department of Education runs modular kindy, pre-primary and toilet block programs each school year.
Does a public toilet block need a building permit?
Generally, yes. A building surveyor or certifier assesses it, and planning approval depends on the zone and land owner.
Who installs the block?
Your builder installs and connects it. EcoPrestige supplies the modules.
