Prefabricated Restroom Buildings for Public Areas – What are the Options?

Delivering reliable amenities in parks, playgrounds, sports grounds, and waterfront reserves shouldn’t be hard work. Prefabricated (kit-set) toilet buildings give councils, schools, and asset owners a faster, cleaner pathway from concept to opening—especially where town water, sewer, or mains power are limited.

1) Choose your services model (off-grid to fully serviced)

Every site is different. LooCube supports multiple pathways so you’re not locked into one approach:

Wastewater: waterless composting toilets or low-water pans with holding tank for sensitive/remote sites; or connect to septic/sewer where available.

Water: rainwater harvesting or tank supply; or connect to town supply.

Power: solar lighting/controls (and composting ventilation) or hard-wired to mains.

This flexibility suits everything from neighbourhood playgrounds and multi-code sports fields to coastal reserves and cycle-trail trailheads.

2) Configure the building to the use

Start simple, scale as needed. LooCube™ modules can be supplied as single, twin, or multi-cubicle blocks with options for:

  • Accessible rooms and ambulant cubicles (see compliance below)
  • Unisex or gendered layouts
  • Showers, change benches, baby-change
  • Service/storerooms for pumps, controls, and cleaning gear

Because the system is modular, adding extra cubicles or a service/storeroom later is straightforward—no need to start again.

3) Build for NZ compliance and safer use

Layouts are developed to support NZS 4121:2001 – Design for access and mobility (as referenced in the NZ Building Code) for accessible routes, clearances, fixtures, and signage. Where an ambulant cubicle is required, projects commonly adopt AS 1428.1:2021 details by agreement with the BCA. We also apply CPTED principles—clear sightlines, even lighting, obvious entries—to reduce misuse and improve user confidence.

Access ramps: FRP ramps feature non-slip, drain-through grating for safe entry in wet conditions and easier cleaning.

4) Materials that last in NZ environments

Aotearoa throws salt air, high UV, and sudden weather shifts at public assets. LooCube™ uses fibre-reinforced polymer (FRP) and coated steel for a corrosion-resistant shell; wipe-clean internal linings; and tamper-resistant hardware. Optional anti-graffiti coatings speed recoveries after incidents. Components are standardised for fast replacement and lower OPEX.

5) Lighting and controls that match the site

Natural light and skylights reduce daytime energy use. After dark, specify vandal-resistant luminaires with timeclock or photo-sensor control. Off-grid sites pair solar lighting with efficient fittings; mains-connected sites can integrate wayfinding and perimeter lighting for safer approaches.

6) Delivery and installation (what to expect)

Scope & consent: confirm layout, services model, accessibility, CPTED, and finishes.

Foundation: slab or piles prepared by your contractor.

Assembly: prefabricated sections are installed and sealed; fixtures fitted.

Commissioning: connect services or activate off-grid systems; open to the public.

With the base ready, on-site assembly is typically measured in days, limiting disruption across public spaces and park operations.

7) Example scenarios (illustrative)

Playground area: two unisex cubicles (one accessible), solar lighting, rainwater hand-wash, holding tank, FRP ramp.

Playing fields: multi-cubicle block with storeroom, hard-wired power, septic or sewer connection, hose-down interior.

Coastal reserve: zero discharge composting toilet, anti-graffiti interior, photo-sensitive lighting.
