Tetragon 2014


TETRAGON – The new public toilet building for any environment Adaptble to suit your requirements, the Tetragon public toilet is flexible both in size and design, with the ability to withstand vandalism. Town centres, service stations, beaches, recreational areas – the flexible design of the Tetragon means that the toilet building can be adapted to blend in to any local environment. Delivered as a complete turn-key package, the Tetragon is quickly craned into place which miminises any disturbance during the installation phase. The robust interior fittings are developed with a focus on hygiene and are quickly and easily replacable in case of any damage. The whole building is portable which means that it can be moved to a new location should there be any change in needs or town planning.
