Portable toilets, often referred to as porta-potties, Port-a-Johns (American English), or Portaloos (UK), ("Portaloo" is a UK and European Community registered trade mark[1]) are simple portable enclosures containing a chemical toilet (a toilet bowl filled with disinfectant instead of water) which are typically used as a temporary toilet for construction sites or large gatherings because of their durability and convenience. Most portable toilets have black open-front U-shaped toilet seats with a cover.
