Custom planning with our DIY sets
You can plan and equip your DIY composting toilet with a 6.5l, 11l or 22l solids container as required.
For a 15 mm thick toilet body, for example, the external dimensions are 395 x 340 x 341 mm when using the 6.5l solids container or 470 x 320 x 462 mm for the 11l solids container and 525 x 380 x 462 mm (DxWxH) for the 22l solids container.
For the internal dimensions of your composting toilet, you should calculate with at least 365 x 310 x 308 mm for the 6.5l solids container or 450 x 290 x 429 mm for the 11l solids container and 495 x 350 x 429 mm (DxWxH) for the 22l solids container.
Important note: To ensure that your toilet body is compatible with our toilet seats when using the 6.5l solids container, you should choose slightly larger external dimensions.
Specifically, the external dimensions should be at least 450x340x341 mm when using the wooden toilet seat.
