Installation

The Kekkilä Composting 

Dry 

Toilet may be installed in an existing or new building. Remember to ensure that 

at least 500 mm of free space remains underneath the toilet building, because the Kekkilä Composting 

Dry 

Toilet is installed through the floor of the building, and the sitting height is 425 mm.

1.  Ensure that the package contents are as listed, and acquire a sufficiently long air-ventilation pipe (diameter: 75 mm; 

length: one metre from the toilet body to above the ridge of the building).

2.  Prepare a level load-bearing foundation underneath the toilet body. We recommend installing the body, for 

example, on top of 50 mm lightweight breeze blocks, placed over a frost-resistant ballast bed. This ensures steady 
installation of the toilet and facilitates emptying. Ensure again that there is 500 mm of free space below the floor.

3.  Use the included template to outline the aperture on the floor of the toilet building. Use a coping saw to cut along 

the lines.

4.  Detach the emptying hatch from the toilet body, and embed the body in its place. The skirt of the toilet body hides 

any unevenness created during the sawing.

5.  Attach the emptying hatch in its place at the back.
6.  By hand, fasten the hose, seepage strainer spindle and pre-attached overflow hose tightly onto 

the toilet body, and guide the overflow hose into the seepage canister, which must be placed in 
a hole dug in the ground. NOTE: Overflow liquids must not be drained directly into the ground!

7.  Install the ventilation pipe (not included) in the connection on top of the toilet. The pipe must 

be led through the ceiling and must reach one metre above the ridge of the building. The pipe 
lead-through should be sealed carefully, to prevent water leaks. Suitable pipe package´s pipe 
dimension is 75 mm. 75 mm pipe shall be installed on top of the adapter, not around it. The 
compatibility of the toilets and pipes vary, and the installation might be a bit loose. This does not 
affect the air ventilation or cause odor problems. Installation may be secured by: saw around 7 
cm piece of the pipe, connect it to the adapter end of the pipe and connect this end of the pipe 
to the dry toilet´s air ventilation adapter.

8.  Attach the included ventilation pipe cap to the end of the pipe. It prevents rain and insects from 

entering the toilet.

9.  Put the thermal seat in place.

Before use

Use of the Kekkilä Composting 

Dry 

Toilet does not require complex preparations. Make a layer 

of approximately 5 cm of rough branch chips or twigs. This prevents the overflow connection from 
clogging. Ensure that the emptying hatch is tightly closed and that the overflow hose is attached to 
the hose spindle and leads to the seepage canister, so that the liquids cannot be absorbed directly into the soil.

Operation

The Kekkilä Composting 

Dry 

Toilet does not need any external energy to operate. The composting is a natural process 

that the heat insulation of the composting toilet makes more efficient. In addition, the liquids seeping through the material 
maintain the moisture needed for the composting process.

The Kekkilä Composting 

Dry 

Toilet is nearly as easy to operate as a water toilet. However, the waste must be covered 

with desiccant after each use. Use approximately 2–5 dl of desiccant at a time. To ensure correct consistency, nitrogen 
balance, and therefore efficient composting by the toilet, we recommend using Kekkilä Desiccant for Dry Toilets. 

Always close the thermal toilet seat lid after use, to guarantee proper ventilation of the toilet and avoid unpleasant 
odours.
