Comparison to Other Waterless Toilets

We combine the best of all current technology with a bit of TFP innovation.

With respect to our predecessors, learn why the TFP Composting Toilet might just be the toilet solution for you.

first of all...our toilet:

 TfP Composting Toilet  - Medium-sized footprint (29.5" high x18. 25" wide) - including the urine collection container at the back.  - Uses urine diversion with collection behind the unit into a 2.5-gallon container which is easily removed without opening the toilet.  - Uses a two-chamber system (rotating drum and finishing drawer).  - Uses a rotating drum technology to accelerate aerobic composting.  - Uses a medium sized (7-gallon) rotating drum technology to accelerate aerobic composting.  - Uses a relatively large finishing chamber (6-gallon).  - Includes a standard sized toilet seat that can be easily swapped out with an alternative off-the-shelf seat if desired.  - Made with HDPE manufactured from recycled materials.  - Uses off-the-shelf components so it is easy to source extra containers or spare parts.  - $895 with free shipping in the continental USA

Two-chamber Composting

  • Relatively large footprint (32"high x 23" wide).

  • Does not use urine diversion. After urine comes in contact with feces, it drains into a chamber with a 2.4 amp heating element to dehydrate pathogenic leachate discharge.

  • Uses a two-chamber system (rotating drum and finishing drawer)

  • Uses a rotating drum technology to accelerate aerobic composting.

  • Relatively large rotating drum with a gear system for turning.

  • Relatively small (4-gallon) finishing chamber.

  • To repair would require specialized parts from the manufacturer.

  • $1500+

single-chamber Composting

  • Relatively small footprint (20" high x 19" wide).
  • Uses urine diversion with collection into a 2.2-gallon container which is removed by opening the top of the unit (which exposes the solid waste chamber).
  • Uses a spinning auger technology to accelerate aerobic composting.
  • Uses a single-chamber with 7-gallon total solid waste capacity. When emptying, both fresh waste and composted material are mixed together.
  • Custom seat molded into the system - no option to use an off-the-shelf toilet seat. 
  • To repair would require specialized parts from the manufacturer.
  • $900+

dry toilet

  • Medium-sized footprint (25" high x 22" wide).
  • Does not use urine diversion.
  • Uses single-use disposable foil and plastic liners to contain and seal the solid and liquid waste.
  • Foil, waste, and plastic liners are disposed of in the landfill or incinerated.
  • Liners must be regularly replaced.
  • To repair would require specialized parts from the manufacturer.
  • $1000+ (plus recurring cost of plastic liner refills)
