We offer three prefab buildings: the Poobah (made in USA), the Wishbone (made in Canada) and the Pan Abode (made in USA). Custom or site-built options exist, but these tend to be more expensive to build and maintain than our pre-fab and warrantied products.


The Poobah is Toilet Tech's strongest prefab building. We designed the heavy-duty structure to withstand the rubbing of buffalo at Antelope Island State Park, Utah. This building package is suitable for both solid waste systems (Decompose and Waste Away) and comes in two sizes (Standard and ADA). This building can withstand a high snow load.

Benefits: Heavy-duty; prefab; 4-season use, high snow load

Drawbacks: Not as light or easy to assemble as Wishbone John

Site Suitability: Winter use sites, high snow load, trail heads, back-country



We are all about reusing waste as much as we are about minimizing it. Our Wishbone prefab building frames are made from extruded aluminum and use recycled plastic or cedar wall boards. These buildings are available for both solid waste systems  (Decompose, and Waste Away) and comes in two sizes (Standard and ADA). We offer single stalls or joined blocks (wall-sharing) connecting up to 5 stalls. This building can withstand a low snow load.

Benefits: Long-lasting (40+ years), prefab, lightweight; erects in a few hours with basic hand tools; will not rot, corrode, fade; multiple color options

Drawbacks: Not made of concrete (but we think concrete toilets are pretty ugly), Not suitable for high snow load

Site Suitability: City parks, parking lots, trail heads, back-country

Warranty: Wall boards - 50 years;  Frame - 5 years

Benefits: Site-specific custom design

Drawbacks: Higher cost

Site Suitability: Trailheads; campgrounds; backcountry

Compatible Vaults: DCV or custom
