SPARK Portable Toilets are mobile restroom units primarily made from Glass Reinforced Plastic (GRP), a material known for its lightweight durability and excellent strength-to-weight ratio. Designed for use in locations where permanent facilities are unavailable—such as construction sites, outdoor events, festivals, and campsites—these units provide fully functional restroom solutions. Each GRP toilet is equipped with essential features, including integrated toilet and sink units, ensuring convenience and hygiene for users.
