Eco Hire Toilets for Building Sites

We hire toilets for building sites. All of our single hire portable toilets and urinals are environmentally friendly eco loos. This is achieved by removing the wash basin and paper towels and replacing them with hospital grade anti-bacterial hand sanitiser. We have found this dramatically reduces water consumption, leading to fewer replenishments whilst offering a cleaner experience for the users. It ultimately reduces the cost of your hire, so it’s good for the environment and cheaper too.

Single unit porta loos are the most popular choice as hire toilets for smaller building sites and festivals or events as they can be positioned almost anywhere making them the ideal solution.

Site Storage

We have all the site storage you could need to hire or buy. Within our extensive range, all containers are factory fitted with a thick steel lockbox and supplied with a locking bolt. All standard containers are fitted with a 4 locking bars ensuring maximum security. The shipping containers can also be supplied with windows and doors and are fitted with high security 5 point locking system doors, whilst windows are 3′ x 3′ with security shutters and two shoot bolt locks per shutter.

All containers are delivered to site by experienced drivers with a crane-assisted vehicle.

Multiple containers can be positioned side by side or back to back and if needed can be altered to be double or triple width for the convenience of a workshop. Containers can be supplied with power, plumbing and lighting allowing for an easy working environment. All containers are water tight and can be supplied with heaters upon request.
