Benefits of CompoCloset’s Tiny House Toilets


Our sustainable toilets are made for compact living, without compromising comfort. Here’s why they’re a favorite among tiny home dwellers, vanlifers, and off-grid adventurers alike:

  • Space-smart design: Fits easily into tiny bathrooms, under benches, or in closets.
  • No plumbing required: No septic tank, no outhouses. Just freedom.
  • Odor control built-in: Thanks to urine diversion, sealed chambers, and optional ventilation.
  • Low maintenance: Easy-to-empty bins, LED liquid indicators, and zero chemicals.
  • Eco-conscious: Save water, skip the chemicals, and reduce your footprint.

Which Tiny House Toilet Should You Choose?


A few things you should ask yourself when making your selection are: 

  • How many people will be using the toilet?
  • Will you have access to dispose of bagged solids?
  • Do you have space to compost?
  • Will you be using your tiny house toilet full time?
  • Do you need a portable toilet to move between dwellings?
