Installing a Villa 9000 unit on a free of water cottage

A toilet for a cottage without water

In Jockis, Finland, there is a small cottage where there is electricity, but no running water or sanitation. The whole family loves to spend time together there. It is only about 20m from the cottage to the outdoor loo, but it has become more difficult for our grandmother to walk. In the autumn of 2016, the family sat down by the the barbeque and decided to get an indoor loo to the cottage because there are now comfortable and odorless dry toilets that also look like regular water toilets.

Choice of toilet and location for the installation

The cottage is only a little over 30 m2 and it was impossible to find space for the toilet inside the cottage. Therefore, we began to think about the terrace or the porch as possible places for the installation. There is a couple of steps down to the terrace so then there was only the porch left as an alternative. There was a little more room on the back of the porch but there were also two large windows that should have needed to be replaced with smaller windows. Had we installed the toilet there, it would have been difficult to use the rest of the room in a good way. The idea grew more during the winter and during the first warm weekend in May, it was decided to start the project and the correct toilet had already been chosen. The choice of toilet fell on the urine separating Separett Villa 9000. The toilet fit well into the room due to price, appearance and capacity. The floor of the porch was cleared and the toilet was put into the room. Finally, we found a place in the corner, on the right next to the front door, where there was room for shoes and jackets. The toilet space was 75 cm wide and 95 cm deep wall to wall. The toilet itself is 46.5 cm wide and 67.2 cm deep. The cottage is only a little over 30 m2 and it was impossible to find space for the toilet inside the cottage.


One wall was built

The wall would not get particularly thick, but it would be robust enough to make it safe to take support on it. Support for the wall was screwed into the floor and in the ceiling. The material used to build the wall was what ever we could find in the shed. This time it was a regular board that was 9.5-12.5 cm wide.


In the shed there was also wood panel and both inside and outside of the toilet room were covered with it. On the inside wall, you had to mount the wood panel horizontally, as it began to run out.



Next to the new toilet space is the door to the house itself and therefore a bellows door was chosen for the toilet space. The door takes some space from the inside and there was not much room for your feet when you sat on the toilet. The porch is made of wood so it was easy to remove the wood panel behind the toilet and get 10 cm extra space behind the toilet. The panel was easily sawed out with a jigsaw.


The toilet installation

The Separett Villa 9000 was attached to the floor with 3 screws as pre-marked in the toilet. Two holes were drilled in the wall to install the pipes from the toilet. A 75 mm hole was required for the ventilation pipe that is placed on the top of the toilet. The urine is led through a urine hose which needs a 32 mm hole through the wall. The ventilation pipe was drawn out through the wall and up through the roof of the porch but not all the way up through the roof of the cottage. There is hardly any smell from the toilet so this was enough. For urine handling, the Separett Ejektortank was dug into the ground a bit. When the tank begins to be full, the float raises a stick that shows that it is time to empty the tank. Here water is pumped from a rainwater well to the tank and the urine is mixed with water to a good blend of nutrient that is watered out. We find it simple and smooth that you do not have to handle the urine yourself.



On the veranda there are no electrical outlets, so at the moment it is connected with an extension cable. An installer is on his way and then there will be electricity for the toilet and for a lamp. It was also planned to install a window here, but that may be a later project.


Much of the use will take place by night, when it is raining and in the dark nights of the autumn. Of course everyone was urged to try the toilet, and that it is so comfortable and odorless has surprised everyone. Now in this little cottage you can enjoy a toilet indoors and you can also use all residues as nutrition. Biobags are emptied into existing outside loo and urine is spread to the lawn and to the bushes.

With the Villa 9000, the standard for environmentally friendly toilets has been set higher than ever. In terms of design, stability, comfort and use, it is the equal of a modern WC in every way. The built-in, 2-speed fan expels odours and condensation from the toilet and bathroom quietly and effectively. The venting duct can be run straight through an outer wall.

The ventilation kit contains 2 x 1 meter white pipe, joint pipe and wall brackets. With the toilet comes a wind cowl and everything else you need for a simple installation of a urine separating toilet.


The toilet solution was built by one person during two weekends and overall it took about 12 hours. The carpenter is an office worker, so no professional need for this installation. In the construction of wall and panel mounting, different lengths of screws and nails were screwed with a screwdriver or nailed with a hammer. The wood panel behind the toilet was sawed out with a jigsaw. Holes through the walls were made with hole drills. The wall bracket for the ventilation pipe was screwed with a screw and the pipe itself was fixed to the wall bracket with a coupling. Building the wall was the most time consuming in this project. In total, it took about 8 hours to build the wall and saw the wood panel out behind the toilet. Drilling holes in the wall, sawing and installing pipes, making the roof cover and sealing with silicone took about 4 hours. The installation of the toilet is done very quickly when it is delivered complete.
