Off-Grid Comfort Meets Elevated Living

Treehouses aren’t just for kids anymore. Whether you’re building a cozy treetop retreat, a backyard hideaway, or a full-scale glamping escape, one thing can make or break the experience: the bathroom.

Say goodbye to awkward outhouses or making midnight trips to the main house. With a Sun-Mar composting toilet, your treehouse gets the upgrade it deserves—a clean, odor-free, waterless toilet system that’s as eco-friendly as your surroundings.

Nature-Inspired, Living Without the Compromise

Installing plumbing in a treehouse is most often impossible. Sun-Mar’s compost toilets are the perfect solution for elevated living spaces, offering everything you need:

You get modern bathroom facilities without disturbing the natural setting.

Easy to Install, Easy to Maintain

Sun-Mar composting toilets are designed for flexibility. Whether your treehouse has power or not, there’s a model for you:

  • Electric models – Ideal for glamping treehouses with access to the power grid
  • Non-electric models – Perfect for remote, rustic builds with zero utilities

Installation is simple and maintenance is minimal. Just turn the drum to mix compost, add Compost Sure, and empty the finished compost typically once per year for seasonal use.

Protect Your Environment

Treehouses are all about being closer to nature. Sun-Mar helps you stay true to that vision. Unlike septic systems or chemical toilets, Sun-Mar toilets use a natural, aerobic composting process to fully break down waste safely and sustainably.

That means:

  • No groundwater contamination
  • No harmful chemicals
  • No wasteful water usage

Sun-Mar composting toilets work in harmony with your environment—whether you’re in a forest canopy or backyard tree.
