Installing a villa 9010 unit on a detached cottage

A toilet for a house without water

In Jockis, Finland, there is a small house with electricity, but no running water or sanitation. The whole family loves to spend time together. The old toilet is only 20 meters from the outdoor cottage, but it has become more difficult for our grandmother to walk. In the fall of 2016, the family sat down at the barbecue and decided to get an indoor toilet as there are now comfortable and odorless dry toilets that also look like regular water toilets.

Choice of toilet and location for installation

The cottage is only a little over 30 m2 and it was impossible to find space for the toilet in the cottage. Therefore, we started thinking about the terrace or veranda as possible places for the installation. There are a few stairs to the terrace so there was only the veranda as an alternative. There was a little bit more space at the back of the porch but there were also two large windows to be replaced with smaller ones. If we had installed the toilet there it would have been difficult to use the rest of the room properly. The idea grew more during the winter and during the first warm weekend in May, it was decided to start the project and the right toilet had already been chosen. The toilet choice fell on Separett Villa 9010 which separated the urine. The toilet fitted well in the room because of its appearance and capacity. The veranda floor had been cleared and the toilet had been placed in the room. Finally we found a spot in the corner, right next to the front door, where there was room for shoes and coats. The toilet room was 75 cm wide and 95 cm deep from wall to wall. The toilet itself is 46.5 cm wide and 67.2 cm deep.

One wall has been built

The wall wouldn’t be particularly thick, but it would be robust enough to make it safe to get support. Wall support was screwed into the floor and ceiling. The material used to build the wall was what we once found in the shed. This time it was a regular plate that was 9.5-12.5 cm wide.

There was also a wooden panel in the shed and covered both inside and outside the toilet area. On the inner wall you had to mount the wooden panel horizontally when it was almost finished.


In addition to the new toilet room, the door to the house itself is therefore chosen for a bellows door for the toilet room. The door takes up some space from the inside and there was not much room for your feet when you were on the toilet. The veranda is made of wood, so it was easy to remove the wooden panel behind the toilet and get 10 cm extra space behind the toilet. The panel could be easily cut with a jigsaw.

The toilet installation

The Separett Villa 9010 was fixed to the floor with 3 screws, as indicated in the toilet beforehand. Two holes were drilled in the wall to install the pipes from the toilet. A 75mm hole was required for the ventilation tube placed on top of the toilet. The urine is passed through a urethra that needs a 32mm opening through the wall. The ventilation pipe was pulled out through the wall through the roof of the porch, but not all the way up through the roof of the cottage. There is hardly any odor from the toilet, so this was enough. For the treatment of urine, the Separett Ejektortank was dug a little into the ground. When the tank starts to fill up, the float lifts a stick to indicate 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 mix of nutrients that are carried away. We think it’s simple and straightforward that you don’t have to deal with the urine yourself.


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


Much of the use will take place at night, when it rains and in the dark nights of 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 house we can enjoy the toilet indoors. And we can use all residues as compost. Biobags are emptied into the existing outdoor area and the urine is distributed to the lawn and to the bushes.


With the Villa 9010, the standard for environmentally friendly toilets has been set higher than ever. In terms of design, stability, comfort and use, it is in all respects equal to a modern toilet. The built-in fan removes odors and condensation from the toilet and bathroom, quietly and effectively. The venting channel can be led straight through an outside wall.

The 50-liter tank is sufficient for holiday homes that are emptied every second or third week. A float indicates when the tank is full. The Ejektortank mixes urine and water and is automatically emptied and cleaned without user intervention.

The Ejektortank is connected to a 1/2 “garden hose.

A 10 meter 3/4 “delivery hose with a 50 cm nozzle is included. (The hose can be extended up to 20 meters).

The ventilation kit contains 2 x 1 meter white pipe, connecting pipe and wall brackets. The toilet comes with a windshield and everything else you need for easy installation of a urine separating toilet.


The toilet solution was built by two people over two weekends and in total 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, several pieces of screws and nails were screwed with a screwdriver or nailed with a hammer. The wooden panel behind the toilet was cut with a jigsaw. Holes through the walls are made with hole drills. The wall bracket for the ventilation pipe was screwed with a screw and the pipe itself was attached 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 behind the toilet. Drilling holes in the wall, sawing and installing pipes, making the roofing and sealing with silicone took about 4 hours.
