What is a crane toilet?
A crane toilet is a portable restroom built on a reinforced frame with certified lifting points, so it can be lifted by crane to an upper floor of a building under construction. It saves crews the time lost travelling to ground level. The unit is lowered periodically for servicing. Call 1-833-520-0680.
Who is this unit for?
Tower and high rise construction- Multi storey commercial builds
- Steel erection and curtain wall crews
- Bridge, silo and industrial structure work
- Any site where ground level access costs significant time
What are the specifications?
| Spec | Detail |
|---|---|
| Lifting | Integral frame with certified lifting points |
| Base | Reinforced, four point lift |
| Tank | Sealed, typically 60 to 70 gallons |
| Servicing method | Lowered to ground level, or pumped in place where reachable |
| Securing | Must be tied or anchored once landed |
| Crane time | Provided by the site, not the rental |
What problem does this solve?
Travel time. On a 20 storey structure, a worker leaving the working floor for a ground level restroom and returning can lose a meaningful part of an hour, hoist queues included. Multiply that across a crew and across a day and the arithmetic is straightforward.
A unit on or near the working floor removes that trip. It is one of the few welfare provisions on a site that pays for itself in measurable productivity.
How is the unit built differently?
The base and walls are reinforced, and the unit carries an integral lifting frame with certified lifting points rated for the loaded weight. A standard porta potty has none of that and must never be lifted by crane.
The tank is also sealed for lifting rather than simply vented, because the unit will be moved while it contains waste.
How does servicing work at height?
Two arrangements. The common one is lowering the unit to ground level on a scheduled lift, pumping and cleaning it there, then lifting it back. The alternative is pumping in place where the hose can reach from a lower level or an adjacent position.
Either way the servicing has to be coordinated with crane availability, which means the restroom joins the site’s lift schedule rather than sitting outside it.
What are the safety requirements?
Securing the unit once landed is the critical one. An empty or lightly loaded portable restroom on an exposed floor is vulnerable in wind, and an unsecured unit becomes a falling object hazard. Most sites make tying or anchoring a condition of the lift.
Beyond that, land it on firm level decking, well back from unprotected edges and floor openings, and check the lifting points before each lift as part of the normal rigging inspection.
How many units does a tower need?
The OSHA ratio applies as it does anywhere, based on the peak crew on site. The practical pattern on tall buildings is a unit on every second or third active floor, which keeps the walk short without adding a crane lift for every level.
As the structure rises and crews move up, the units move with them. Plan that into the lift schedule rather than treating each move as an exception.
How does booking work?
Call with the headcount and dates
We connect you with a local provider. Tell them whether workers or guests will be using the units.
Confirm the count and the schedule
The provider sets the unit mix, the servicing frequency and the placement, then quotes the whole rental.
Delivery, servicing and collection
Units arrive clean. The service truck keeps to the agreed schedule, and collection is on the end date.
What does it cost?
| Market type | Typical range |
|---|---|
| Monthly, major metro | $350 to $600 |
| Monthly, mid size city | $300 to $500 |
| Monthly, smaller market | $250 to $450 |
What is inside the unit?
Included
- Molded seat with a self closing lid
- Sealed holding tank designed for lifting
- Toilet paper holder and hand sanitiser dispenser
- Non slip floor
- Reinforced walls and base for repeated lifts
- Lifting eyes or frame rated for the loaded unit
Servicing schedule
Weekly unit lowered to ground level for pumping and cleaning, then lifted back.- In place pumped at height where hose reach allows, which avoids a crane lift.
- Per lift crane time is scheduled by the site, usually alongside other material movements.
Fittings vary slightly between manufacturers. Your provider confirms what the specific unit includes and how often it will be serviced.
Where should the unit go?
Land the unit on a firm, level deck away from edges and openings, and secure it immediately. An unsecured unit at height is a serious hazard in wind, and most sites require it to be tied or anchored as a condition of the lift.
A standard unit occupies roughly 4 by 4 feet with the door opening outward, so allow about 5 by 5 feet of clear space. The service truck needs to get within about 25 feet of the unit, which is the constraint that decides most placement questions.

High Rise Crane Toilet questions
Why use a crane toilet instead of a ground level unit?
Time. On a tall structure, a crew member travelling to ground level and back can lose 20 minutes or more per trip. A unit on the working floor removes that.
Is the unit different from a standard porta potty?
Yes. It has a reinforced base and walls plus an integral lifting frame with certified lifting points, because it is designed to be lifted while loaded.
Who provides the crane?
The site. Crane time is scheduled by the contractor, usually alongside other material movements, and is not part of the rental rate.
How is it serviced?
Either lowered to ground level for pumping and cleaning, or pumped in place where the hose can reach. Lowering is the more common arrangement.
Does it need to be secured once landed?
Yes, always. An unsecured unit at height is a serious wind hazard, and most sites require tying or anchoring as a condition of the lift.
How many units does a high rise need?
The OSHA ratio still applies, based on the peak crew. In practice many towers run a unit on every second or third active floor rather than one per level.
