Thinktank Waterless Toilet
Questions about this product
Questions about this product
What is the ThinkTank Waterless Toilet and how does it prevent smells?
It’s a urine-diverting, waterless toilet that separates liquids from solids and uses sealed 3 inch intake and exhaust vents with fans to keep negative pressure in the toilet. That design eliminates room odours
Does it need power or water?
This toilet doesn’t require water. It uses a low-draw 12V fan (about 2.5W) and includes a 110-120V wall transformer, allowing you to run it from a small battery or a standard outlet.
How do I handle urine, and what size is the drain?
Urine exits the rear of the toilet at about 7 inches height. Connect it to 1 inch PVC or ABS pipe or a 1 inch ID hose and route to a tank, French drain, or approved greywater system. Always follow local rules for urine disposal.
How often do I empty the solids and what’s included?
Plan on roughly 50 solid uses per empty, depending on users and cover habits. In the box you get the solids container with lid plus the key vent parts for intake and exhaust.
Any install tips to keep odors down outside?
To minimize odours, terminate the 3-inch exhaust pipe away from doors, decks, and windows. Use the supplied intake and exhaust as directed. It’s normal to have a slight odour near the vent cap, as this is expected for any vented system.

- Thinktank Waterless Composting Toilets are virtually airtight under normal operating conditions! They draw ventilation from outside – in contrast to other toilets which draw ventilation air from the bathroom area. With other toilets, you are rapidly blowing expensively heated or cooled air outside. The Thinktank Waterless Composting Toilet, through its patented airtight design, draws all ventilation air from outside, circulates it through the toilet, and exhausts the same air outside. This saves a great deal of money over time, is far more efficient, and environmentally friendly. Please see the photo of the lid, showing the soft silicone tubing which pushes down into the bowl when closed – creating an airtight seal. No other toilet has this patented technology!
- MUCH EASIER TO CLEAN! Most waterless and composting toilets have a bowl, with a small trap door for solid waste. A mess results, every time. The Thinktank Waterless Composting toilet utilizes a large chute, with vertical walls. Very little or no waste will hit the sides, and clean up is easier. Look at the picture of the massive opening! It needs FAR LESS CLEANING.
- Because the Thinktank Waterless urine diverting toilet is tightly sealed, ingress by insects is virtually impossible. This solves a major problem with other waterless and composting toilets.
- The patented trap door design allows men to stand when urinating – in contrast to other toilets where men must sit. The trap door stays closed unless you are going #2. It is impossible for the urine to end up in the solids bin – which is a big problem with other toilets. Please see the photo of the patented trap door. Note the metal disks, which are powerful rare earth magnets that hold the trap door securely closed or open.
- Urine exits the toilet via a drain tube, 7 inches high, at the rear of the toilet. There is a 5′ flexible drain hose that you can lead to the location of your choosing. This is typically a French drain, gray water system, or tank.
- BETTER LOOKING DESIGN – with vent pipes hidden behind the toilet in most installations (in contrast to other toilets, with vent pipes coming out the top or out the side).
- Thinktank Waterless Toilets use the best fans in the world. They have exceptional output (high cubic feet per minute rating), powerful static pressure (strength of airflow rating), are very quiet, draw low power, and have an incredibly long life (rated at 150,000 hours). The toilets are designed for the fan to be easily accessible and removable.
- Very quick and easy to empty. Waste is contained inside a compostable bag.
- All metal parts are high quality marine grade stainless steel.
- The toilet is incredibly strong. The shell is rotationally molded like a white water kayak. This is the strongest possible way to build something in plastic. Rated at 350lbs plus. Big guy approved!
- Works on either 12 volt (a deep cycle 12 volt battery) or 110 volt power (normal household electricity) with the supplied wall transformer.
- Uses inexpensive, widely available compostable bags.
- Never need to add peat moss, saw dust, or turn a handle.
- If you have small children – you can use a standard inexpensive child seat. No need to buy an expensive urine diverting child seat.
- BEST WARRANTY IN THE INDUSTRY. The toilet is covered for 6 years. (3 years on the fan. The fan is inexpensive and easy to replace).
- Glad tall composting bags. 23-40 Litre bags or 8 Gallon
