The single most important consideration is to ensure you have adequate space for a medium size van or 4x4 vehicle with trailer to deliver the toilet(s). As a rough guide, please allow 9ft width and 12ft height clearance at the site location. You will find the dimensions for each type of unit on the product pages of our website and additional space needs to be allowed for manoeuvring, turning and getting in to the mobile toilet unit. Toilets should be placed on flat, firm ground (ideally gravel, tarmac, concrete or hard-standing), but can also be on grass as long as it’s not too wet!). We don’t want to damage lawns or driveways when man-handling toilets into their final position, so it’s always worth having a ‘Plan B’ for where to site the units as unfortunately we cannot be liable for any accidental damage caused at the delivery address.
