This product was an excellent choice for us in our tiny house
Easy install. Just needed to buy flexible hose and clamp also cut a vent hole in wall and cover the exit. (Verified Homedepot.com review)
Great Tiny home toilet
Perfect for our tiny home. No smell due to the separation of solids and liquids and a very quiet fan. Durable design, fast delivery. (Verified Home Depot Canada review)
It size feels like using a normal toilet so the familiarity is there.
We bought this a few months ago for our airstream. We live full-time on the go in it and have had a chance to leave a thorough review. We had a cassette toilet previously that felt like a small children’s toilet trainer. The capacity of the liquid waste is more than you’d ever need. We empty it regularly since that seems to be the thing that smells the most. 12v power for the fan is easy to hook up and it exhausts out the back and keeps odor down to nothing and helps the waste start to compost. The mounting brackets are great but it can easily be moved out of the way if needed. The portability and size is what sold us but after using it we’ve found it better than a natures head or other competitor brands. With coconut husk and biodegradable bags this thing is the solution for off-grid, responsible, hygienic toilets. (Verified Home Depot.com review)
Easy to install
Swapped out the original toilet in our camper. Easy to clean. Usually line with a plastic bag to keep the clean up easy. No more black water tank to worry about. (Amazon verified review)
