The basic principle
Why our toilets work without connections
Portable toilets are deliberately designed to work independently of the infrastructure at the location.
Unlike a permanently installed WC in a building, a portable toilet is built to work at practically any suitable location: on a construction site without a finished service connection, on a meadow without sewerage or in a car park with no power box nearby. This is made possible by a closed system of waste tank, chemical or biological treatment and, with the appropriate equipment, a separate fresh-water tank for the hand-wash basin.
For you as the renter this means one thing above all: as a rule you need not think about connections, and can concentrate on which product suits your project and where it may be placed. Read more about choosing the site in the article “Where can a portable toilet be placed?”.
Standard toilet cabin and urinal stand: no connection at all
Our standard toilet cabin and the urinal stand need neither a water nor a power connection. Both products work with a closed tank system that is emptied, cleaned and refilled during the regular service. That makes them particularly suitable for construction sites in early phases or for locations on open ground where no infrastructure exists.
Toilet cabin with hand-wash basin and hand-wash station: own water tank
If you want to offer your guests or staff somewhere to wash their hands, the toilet cabin with hand-wash basin or the separate hand-wash station are the options. Both carry their own fresh-water tank, which feeds the basin. No connection to the local water supply is needed: the tank is filled on delivery and topped up as part of the agreed service interval.
Accessible toilet cabin
The accessible toilet cabin also works on the same principle and needs no fixed connection on site. The wider cabin with ramp and grab rails differs in its equipment, not in its connection requirements.
When a power connection still plays a role
- Additional lighting, for example at evening events or use at dusk
- Heating in the cold season, when a unit is operated outdoors over a longer period
- Electrical add-ons that go beyond the standard version
If one of these points applies to you, it is best to clarify it with us when you make your enquiry, so that the right equipment and any connection needed on site can be planned in.
What this means for choosing the site
Because our units work self-sufficiently, you are considerably more flexible in choosing the site than with permanently connected sanitary facilities. More important than proximity to a connection are a firm, level surface and an access route our service vehicles can reach. Whether a particular area is suitable and whose consent you should obtain beforehand is best clarified with the owner of the land, the client or organiser and, for public land, with the responsible authority.
Frequently asked questions
Does every portable toilet work without a connection?
The standard toilet cabin and the urinal stand are built to work without a water or power connection. Units with a hand-wash basin and hand-wash stations carry their own fresh-water tank instead, so they also need no fixed connection on site.
Where does the water come from in a toilet cabin with a hand-wash basin?
From an integrated fresh-water tank that is filled on delivery and topped up during the service. No connection to the local water supply is needed.
When does a power connection still make sense?
For example if you want additional lighting, heating for the cold season or other electrical equipment. Whether that applies to your project is best discussed directly with us.
What does the lack of a connection mean for the site?
As our units work self-sufficiently, they are much more flexible in terms of location than permanently connected facilities. The area must still be chosen with delivery and service access in mind.
Do I still need to speak to the owner of the land?
Yes. Even without any connection requirements, every placement needs the consent of the owner, client or organiser and, where applicable, consultation with the responsible authority, for example on public land.
