Highly innovative, patented, urine diverting waterless toilet. (Urine diversion is key to odor free composting toilets).

Thinktank Waterless Toilets™ have numerous advantages, and will save you money when compared to other toilets.

  • 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. It’s easy to hit, and it needs far less cleaning.
  • Thintank 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 Thintank 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.
  • Because the Thintank 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.
  • The opening for solid waste is huge, with vertical sides. This overcomes most of the unpleasant clean up associated with many other waterless and / or composting toilets. With other toilets, waste can hit the sides of the bowl, making a mess. With the Thinktank, very little waste will hit the sides, and clean up is easier.
  • 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). Two fans are provided – one for the air intake and one for exhaust. However, in most installations the intake fan will be unnecessary and you can keep it as a spare. The intake fan is useful for very long runs of vent pipe. The toilets are designed for these fans 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. 10 bags are included.
  • Never need to add peat moss, saw dust, or turn a handle.
  • BEST WARRANTY IN THE INDUSTRY. The toilet is covered for 6 years. (3 years on fans. Fans are inexpensive and easy to replace).

  1. Daryl Smith

    We are very impressed. Works as advertised. Happy men can stand to pee! Nice not to be blowing heated air outside constantly as with other toilets.

  2. Janet Michaels

    I could not be more impressed with the Thinktank. Having a tightly sealed toilet is such a good idea. And the customer service is the best.

  3. Brad McInnes

    The toilet is as described. No odour, built like a brick. Richard spent significant time with us, making sure we made the right choice. We are very happy with the Thinktank toilet.

  4. Andrea B

    This toilet is perfect as we are working at getting away from a septic system. The toilet is sturdy, easy to clean, and totally odorless. The fan is nearly silent. Richard is the most responsive sales and support person we have ever worked with. Always had an answer back to us within minutes of our question. We are very happy with this company and with the product. I would buy from them again in a heartbeat.

  5. Darren Matthews

    I didn’t think customer service like this existed anymore. Great, great customer service. And we are very happy with the toilet! It works perfectly.

  6. Kevin Whittaker

    This thing is built like….a tank! Wow, what a surprise. It is very high quality, and an impressive design. No odour as promised.

  7. Karen Osach

    This toilet cost a little more, but it is totally worth it. It is very well made, and does the job.

  8. Richard

    We installed the Thinktank 3 months ago, and are definitely satisfied. We live in a tiny home, and with our previous composting toilet we had odor every time we turned the range fan on. This does not happen with the Thinktank. Zero odor at all times. We had installation questions and they answered the phone on a Sunday! This allowed us to get the job done as planned, rather than have everything delayed. Impressed.

  9. Samantha

    Seems indestructible. Nice design, and very well thought out.

    If you are reading these reviews to help make up your mind about purchasing an eco-toilet I would whole heartedly recommend dealing with CompostingToiletsCanada and Richard Brunt.
    Richard was initially very helpful in recommending the Thinktank eco-toilet to replace an outhouse at our lake cabin in the woods in Nova Scotia. When the unit arrived we were impressed with the size, quality, and mechanism of the unit. Installation was straightforward but we ran into a problem with the closing mechanism. An email to Richard was quickly followed up with a phone call from Richard (despite a 4hr time difference!). The problem was discussed, a solution identified and a new part was expedited right away. Richard continued to follow up personally with emails and videos until we were satisfied that everything was working as it should.
    We now have a group of happy campers thanks to the first rate service we received from Richard and quality of the ThinkTank.

  11. Christine Wakefield

    Outstanding product. Outstanding customer service. This toilet is far better made than our previous urine diverting toilet. And easier for women to use, because we don’t have to aim! Better.
