The SpaceSaver composting toilet is an ideal addition to anywhere a toilet is needed and space is tight. With a width of only 19 1/2″ and depth of 23″, even a closet or small corner can now be turned into a bathroom!

The SpaceSaver is designed to be used when you have tighter spaces. Installations include, but are not limited to: cabins, cottages, homes, yurts, pool houses, cabanas, bunkies, camps, treehouses and workshops. See below for what our customers say about it, and about the Mobile unit*.
* The Mobile composting toilet is no longer in production. For applications where the toilet will not be stationary, the GTG is the perfect fit.

“Bill’s SpaceSaver is installed at the family cottage which is used nearly 365 days a year. He reports that “installation was a ‘snap’, I installed it myself in less than 2 hours.” He opted for a Sun-Mar because of the cost of a septic system and the fact that he didn’t want to disturb the trees around his cottage. He also likes the idea of being able to use the compost for his plants. “I have nothing but praise for the Sun-Mar”, enthuses Bill.” – Bill W.

“Our Sun-Mar is installed in our RV. The RV is on a permanent installation in the Adirondacks. We were unable to secure permission from APA for a septic system thus the composting toilet. We use it 4-5 weeks at a time so far and have been pleased with performance. Aside from a few minor glitches all is going well. We vented it through the bathroom ceiling vent and that works OK. Odor isn’t much of a problem especially when using the exhaust fan through the charcoal filter.” – Michael F.

“One of two in our Live aboard Catamaran. We really are happy with the “purring” fan to ventilate and clean lines and “NO PUMP OUTS – EVER!!” EXCELLENT!” – Steve and Charlene L.

“We use the composter at our remote high desert home. Friends are always fascinated when they first see the composter. It certainly provokes thoughts on solutions for the need to conserve water here in the arid West.” – Ed and Wendi L.
