Customer Questions & Answers

Is this a "Separator" type compost toilet?

Some compost toilets have a front compartment where urine goes, separate from the feces composting bucket. This keeps the compost from stinking [along with good cover material and good venting]. Does BTS 33 composting toilet have a separator to remove urine to a separate disposal tank?
Asked by: Chi
The ez-Loo uses a one bin system. All waste goes into one bin and the liquid wastes are filtered trough the compost material and drained out of the toilet on a continuous basis through a supplied drain hose. There is no odor as long as the toilet is installed and used correctly and the vent system is installed as per our instructions. A properly installed and operated vent system is a critical part of an odor free installation.

Does it need to be built on a platform or is the waste collection in the unit?

I have a small cabin and bathroom on rocky ground and can't dig down. We could lay a drainage pipe but not much more.
Asked by: sarah
The entire toilet sits directly on the floor. There is no waste collection bin other than what is inside the toilet itself. The only time you would need to put this on a platform would be if your floor was concrete. Then you you would construct a small raised platform out of 2 x 2 or 2 x 4 material, with some insulation between the top of the platform and the concrete. This would be to help keep the cold concrete from slowing down the composting process going on inside the toilet.

Can waste be used in garden compost?

Asked by: Becky
The use of human waste compost is regulated by state and local health laws. These laws can vary widely from state to state, but as a general rule, most do not permit the use of this material on fruits or vegetables grown for human consumption. Some states prohibit it's use entirely, while some will allow it's use only after it has first been composted further, in the ground for periods of around two years. It is always best to check with your local health department before using human compost on your garden.

Can the unit be installed in locations with prolonged cold?

I live off grid in alaska and my house will freeze up in the winter if I leave for any amount of time. Can this unit handle that type of climate?
Asked by: Yougene
Around the world, tens of thousands of composting toilets are installed in cold climates such as the Scandinavian countries, Canada, Minnesota, Wisconsin, Alaska, Maine and many other cold areas. Since there is no water in these toilets, there is no danger of cracking due to freezing. Many are in "off the grid" installations such as you describe. The caveat is that the bacteria that perform the composting need to be warm in order for them to "get to work". That threshold is 64 degrees F. and above. The toilet must be installed in an area that will get to that ambient temperature for at least as long as you are there. When you leave the cabin and turn off the heat, the bacteria will go dormant until the temperature rises again to 64 degrees. Composting toilet owners in cold climates understand this limitation and plan accordingly.

Customer Reviews

33 Non-Electric Waterless Toilet is rated 3.4 out of 5 by 5.
Rated 4 out of 5 by from Simple I like this composting toilet but it's too expensive for what it is. Basically you're getting a plastic toilet-shaped bucket. Nothing else. You fill it then empty it. No composting done as such, no turning or work. It's great for my guests who are freaked out by the idea. For me, I'd used the humanure bucket system for years, same idea for much MUCH cheaper. Oh, customer service is terrible. I've emailed four times and heard nothing back.

Rated 3 out of 5 by from everyone should have one but has flaws First off, this product saves water! However it does have one little flaw that can become a headache. The way the drain is set up it holds a small amount of urine. If your drain isn't perfect the urine will back up and flood the bottom of the toilet. I fixed that with some silicone to raise the drain well and build up the drain wall. Also recommend a screen over the top of the vent to keep flies out. Biolet costumer service is good. Much prefer purchasing mulch from home Depot.

Rated 3 out of 5 by from HOME DEPOT-Bad Robots! I advocate for using composting toilets of good design. I really like DIY stores. We spend a LOT of time in HD stores! [and LOTS of money, because _lots_ of projects!] Home Depot appears to have posted videos irrelevant to help anyone learn about composting toilets. The Home Depot "helpful" videos posted on EVERY SINGLE composter they carry, is all about REGULAR toilets, not composting units. Also, they fail to show the insides of the composting toilets...anyone interested REALLY needs to go to the website for those models, to learn more about how they work. Some work better than others; some are not on all State's "approved" lists. Needs more actual details of the composting toilets, or at least a website link for interested shoppers. We've used composting toilets of several types/designs. It's tough to find small size units that work well; certain things make them work better, like: separate the urine out; good venting. Those kinds of features are important to show customers.

Rated 2 out of 5 by from this product fits the bill in price and performance Having no parts that may brake in the use of the composting saves breakage that other composters have. It is easy to use, clean lines, easy to install and costs less than other units that I researched. The customer service has been good and having free shipping to our door saved us more money. So far have had no problems with it.
