Compare composting toilets for tiny homes, including Nature’s Head and GL90 space, maintenance, approvals and installation responsibilities.
Bathroom access and emptying routines often decide which composting toilets for tiny homes will suit you. Nature’s Head keeps its collection chambers inside the bathroom, while the GL90 needs accessible space below the floor.
How Do Composting Toilets for Tiny Homes Differ?
Nature’s Head is a self-contained, urine-diverting toilet with a removable liquid bottle, solids chamber and manual agitator. It still needs ventilation and power for its fan. The GL90 sits over a chamber below a bathroom pedestal, with a second chamber for rotation, ventilation and an excess-liquid drainage arrangement.
Nature’s Head vs GL90: Space, Capacity and Maintenance
Compare access, upkeep and approvals rather than treating two waterless toilets as interchangeable. What we offer varies by range. Our current 12M home inclusions list both Nature’s Head and the GL90 as supply and install upgrades, while our 8M and 9.6M pages list the GL90 as supply only, with final installation arranged by you. Confirm what applies to your model in writing.
- Space: Nature’s Head is listed by Australian suppliers at about 450 mm wide, 475 mm deep and 546 mm high, so allow extra room for operating and servicing. For the GL90, check the manufacturer’s current chamber dimensions and the underfloor clearance it needs.
- Capacity: Emptying frequency depends on occupancy and use. Check the manufacturer’s rated loading against how many people will use the toilet full-time and follow its rotation routine.
- Maintenance: Nature’s Head users empty the urine bottle regularly and use the agitator to mix solids with the composting medium. After the solids chamber is emptied, the base is prepared again with hydrated coir.
- Chamber changes: GL90 users swap the active chamber for the spare and leave the removed material to keep composting. Underfloor access must stay practical and unobstructed.
- Appearance: Nature’s Head has an all-in-one moulded body. The GL90 uses a separate pedestal, with the finish depending on the package.
Which Composting Toilet Should You Choose for Your Tiny Home?
Neither composting toilet option is universally better. The right choice depends on your tiny home’s design, occupancy, maintenance needs and site conditions. Plan for safe waste removal and disposal, and check local approval requirements. For the GL90, ensure decks, pipes and landscaping won’t obstruct chamber removal or servicing.
- Nature’s Head may suit when underfloor clearance is limited, the home might be relocated or you want a fully self-contained installation.
- The GL90 may suit when the home has suitable underfloor clearance and safe chamber access, and its rated loading matches your occupancy.
- Check approvals before ordering. Business Queensland’s composting toilet guidance says buyers must request a written statement of compliance from the manufacturer or distributor and submit it to the local government with the approval application. Product advertising alone can’t tell you what your property needs.
- Plan for greywater separately. A waterless toilet doesn’t deal with wastewater from the shower, vanity, kitchen or laundry, so the site still needs an appropriate wastewater solution.
