Portable Bathrooms for Sale | Durable Prefab Mobile Restroom Units

If you’ve ever run a construction job, set up an outdoor event, or managed a remote work site, you know how critical basic restroom access is — and how much of a headache it can be when permanent plumbing isn’t an option. For sites without built-in facilities, a good portable bathroom isn’t just a convenience — it’s a basic requirement for worker comfort, public health, and regulatory compliance.

At ETODEVICE, we’ve built our reputation on making portable sanitation simple, reliable, and comfortable. For over 17 years, we’ve designed and manufactured prefab portable bathroom units that hold up to heavy use on job sites, at festivals, in campgrounds, and in emergency relief zones. Every unit ships fully assembled and ready to use. Just hook up water, sewer, and power, and you’re good to go — no construction crew, no permits, no weeks of downtime. Today our units are in use in more than 40 countries around the world.

Why Our Portable Bathrooms Stand Out

We didn’t design these to be “good enough for a porta potty.” We built them to feel like a real indoor bathroom, but in a self-contained, movable unit. Here’s what sets them apart from basic plastic portable toilets and cheaper options on the market.

 Ready to use the day they arrive

Every unit comes fully built from the factory. There’s no assembly required, no parts to sort through, and no complicated instructions. Most units can be fully operational within an hour of delivery. They connect directly to standard water and sewer lines, so you don’t need to manage separate holding tanks or schedule frequent pump-outs for daily use. For truly remote sites with no plumbing, we also offer built-in tank options on request.

 Spacious enough to actually feel comfortable

Our standard single unit measures 1,260mm wide × 1,120mm deep × 2,400mm tall on the outside. Inside, there’s enough headroom and floor space to stand, move, and use the fixtures without feeling cramped — a huge upgrade from the tight, claustrophobic plastic porta potties most people are used to. The corner sink layout makes smart use of space, leaving plenty of legroom in front of the toilet.

 Built tough for outdoor conditions

These units are made to live outside, year-round, in all kinds of weather.

• Walls: 40mm thick fiberglass composite panels with a smooth white finish — water-resistant, easy to wipe down, and built to stand up to wind, sun, and minor impacts.
• Frame: Cold-formed steel frame with a powder-coated black finish on the top, base, and door trim for rust resistance and structural rigidity.
• Floor: Layered build for durability and waterproofing: 1.2mm tin-plated steel base sheet, 9mm OSB subfloor, and 2mm thick vinyl flooring. We add a 100mm upturned edge all the way around the floor to stop water from seeping under the walls.
• Door: 40mm aluminum frame with a matching fiberglass composite panel, fitted with a secure lock and a built-in ventilation grille.

 Safe, fully certified electrical systems

We don’t cut corners on wiring. Every electrical component is certified to international standards, and we build every system to avoid the exposed wires and cheap parts that cause safety issues on lower-quality units.

• Full SAA-certified electrical package: distribution box, 10A residual current device (leakage protection), and circuit breaker.
• 1.5mm² SAA-approved sheathed cable throughout.
• All wire connections use terminal blocks — no cut wires, no exposed copper.
• Ground wire is securely fastened to the unit’s metal frame.
• Australian-standard 10A power outlet inside, plus a 5-meter external power cord with a certified plug.
• SAA-certified aluminum LED downlight for bright, even interior lighting.

 Low maintenance, easy to clean

The smooth, non-porous fiberglass walls don’t stain or absorb odors. The vinyl floor is seamless and water-resistant. There are no hard-to-reach cracks or crevices where dirt can build up. Daily cleaning takes just a few minutes with standard cleaning supplies. For long-term sites, periodic checks of plumbing connections and the exhaust fan are all that’s needed to keep the unit running for years.

How to Pick the Right Unit for Your Needs

Not sure which configuration fits your project? Here’s our practical guide based on 17 years of outfitting real-world sites.

 Construction & industrial job sites

• Small short-term jobs (20 workers or fewer): One standard single unit is usually enough.
• Mid-size projects (30–60 workers): Go with a double unit, or two singles. If the site runs year-round and workers stay on site, add a shower unit.
• Large housing or infrastructure projects: Mix of double units and singles, placed evenly around the work area. We can also customize the male/female stall ratio to match your workforce.

 Outdoor events, festivals, and weddings

• Plan roughly one stall per 25–30 guests for all-day events.
• For weddings and upscale venues, our units have a clean, neutral look that fits right in — no bright blue plastic eyesores.
• Always include at least one ADA-compliant unit for public events.

 Campgrounds, parks, and remote tourist sites

• We recommend bathroom-with-shower units for campgrounds and overnight sites.
• Units can be color-matched to fit park aesthetics. No permanent construction means no zoning headaches and no damage to the landscape.

 Disaster relief and temporary medical facilities

• Shower-equipped units are critical for hygiene in relief camps.
• Fast production and shipping mean we can get units to emergency zones quickly.
• ADA units ensure access for people with injuries or mobility needs.

Why Work With ETODEVICE?

As a toilet trailer manufacturer in China, we’ve been focused exclusively on portable restroom and shower equipment since 2008 — that’s over 17 years of refining our designs and manufacturing process. Our factory covers 8,000 square meters, with a team of more than 100 skilled workers, engineers, and quality control staff. Today we ship to over 40 countries across Europe, Oceania, North America, and Africa.

We don’t outsource production. Every unit is built in-house, inspected at every step, and pressure-tested for plumbing and electrical safety before it leaves the factory. We work directly with our customers — no middlemen, no hidden markups.

Don’t just take our word for it. One construction client told us, “We put these on our new housing project, and they’ve held up way better than the old plastic units we used to use. Clean, sturdy, and the workers actually like using them.” A wedding planning company added, “We ordered two units for an outdoor vineyard wedding, and they looked so much nicer than regular porta potties. Our clients couldn’t believe they were portable.”

For sites without built-in facilities, a good portable bathroom isn’t just a convenience — it’s a basic requirement for worker comfort, public health, and regulatory compliance.
