Why We Chose It

Constructed from high-density polyethylene, this unit is built to endure the stresses of road trips and boating excursions. The adult-sized seat is a standout feature, ensuring that users of all ages can use the facility without discomfort or instability.

The Moonwhite colour gives it a clean look, though it may require more frequent external cleaning to look its best. It remains a reliable backup for any household or outdoor enthusiast who prioritises a traditional flushing mechanism over a dry composting system.

  • Adult-sized seat for maximum user comfort
  • Piston pump delivers an efficient full-bowl flush
  • Double-sealed valve prevents leaks and odours
  • Level indicator shows when emptying is required
  • Rotating spout ensures splash-free waste disposal

They use natural bulking agents like peat moss, coconut coir, or hemp to create the ideal environment for aerobic bacteria to break down waste into safe, organic material.

The primary purpose of these products is to offer hygienic waste management in areas without access to traditional sewage infrastructure. By using a waterless design, they conserve precious resources and prevent the contamination of local water sources, making them a favourite for eco-conscious travellers.
