Separett Tiny Installation and Maintenance Guide

About the TINY

Separett Tiny is the worlds most advanced urine diverting toilet, and is designed and developed specifically for Tiny Homes and other small living spaces such as camper vans, caravans, boats, cabins, etc.  You can choose between two versions and save all that extra space much needed in a compact bathroom/shower area.  

The Separett TINY comes in two Versions: 

  1. Tiny with urine tube: Internal collection of solid waste, external collection of urine. 
  2. Tiny with urine container: Internal collection of urine and solid waste.

Choosing the Correct Placement for your TINY:

  • The Separett Tiny has no requirements for room temperature, and works in both cold and warm temperatures. The only requirements are a 12V power source, you must be able to lead the urine away (model with the urine tube), and install a ventilation pipe to expel the fumes. 
  • The Separett TINY is designed to be mounted on the floor, against a wall or a sturdy surface (not free standing), and should be attached either to the floor, wall, or both for that extra stability.
  • Mark the locations of the mounting holes with a marker to ensure your desired  placement of the TINY.

Separett Tiny Installation Steps: 

WARNING! Before making holes in walls or floors. Ensure that the location for wall penetration allows for a hole to be made and that the piping meets construction regulations. Keep in mind that the wall may conceal, for example: electrical wiring, piping, waterproofing, load-bearing construction. IMPORTANT! Always consult your local environmental office to find out what rules apply in your municipality. Always follow local regulations. Please view the Separett installation video at www.separett.com

Installation Step Process:

  1. Make holes according to the installation template
  2. Install ventilation pipe
  3. Install urine hose
  4. Install ventilation pipe cap or ventilation cowl
  5. Power supply for toilet
  6. Connect the toilet to the ventilation pipe and urine tube
  7. Fix the toilet to the wall and/or floor
  8. Install fixed fan filter
  9. Place basket in the urine drain

Mark and Drill your holes according to the installation template in your desired location:  

  • Enclosed with your new TINY is an installation template that provides you multiple installation options for urine drains and ventilation pipes, either through the wall, behind the toilet, or through the floor. These options guide your installation without having to use the visible pipes.

Install the ventilation pipe:

  • The TINY is designed for 50 mm or 1.969 Inch vent pipes (outer diameter). For optimal function it is recommended that you use Separett’s own installation kit that included pipes and angles in the correct manufacturer dimensions. 
  • The Separett TINY can be installed with up to 5 meters, 16.4 feet of ventilation piping, and consist of up to two 90-degree bends. These pipes can installed through a wall, floor, or roof. 
  • Should you need longer venting that exceeds the recommendations above, you may install an extra fan (from the Separett site) for the added boost. The toilet comes with a coupling for connecting the included 40 cm-long 50 mm pipe to a 1.5 inch pipe.


Install the urine hose (not applicable for the TINY with the holding tank):

  • The TINY with the drain tube is delivered with a 2-meter (6.5 ft) urine hose. To correctly attach, use the included straight joint, or the 90-degree joint depending on your application. Like the installation of the ventilation pipes, it is possible to connect the urine tube so that no pipe is visible where the toilet is installed. This is achieved by angling the 90-degree connection downwards or using the straight connection.

` Recommendations for installation of the urine hose:

  • As with the ventilation duct, the Separett TINY provides the option of installing the urine hose without any visible pipes/tubes in the bathroom. Below are a few tips that should be followed to maintain a well-functioning urine outlet over time and all year round.
  • If you are going to go through an insulated wall or a wall with an air gap between the inner and outer wall, you must use a pipe for the penetration, or lead the hose through a pipe. Pipes are used to reduce the risk of pests causing damage to the tube.
  • If you are going to run the urine a longer distance than the 2 meters (6,6 ft) of the supplied hose, you should switch to a pipe after the 2 meters (6,6 ft). Since urine contains minerals that can accumulate in pipes/hoses, we recommend that the subsequent pipe have a diameter of at least 40 mm to avoid blockages.
  • Make sure that you always have a downward inclination of at least 2 degrees (2 cm per meter or 0,8 inch per 40 inch) throughout the piping, also make sure that there are no air pockets created by bends in the hose.
  • If the toilet is to be used in the winter, outdoor pipes must have a diameter of at least 40 mm (1.6”).
  • If the toilet is to be used in winter, we recommend that you insulate outdoor pipes with pipe insulation. This insulation can be bought in most DIY and hardware stores.
  • An important rule for longer installations over 2 meters (6.6 feet) is that the sooner you switch to pipes with a larger diameter, the lower the risk of blockages in the pipes.
  • Do not place pipe joints near electrical appliances or wall sockets. This is to prevent liquid from coming into contact with electricity in the event of a leak. 

Installation of pipe cap or ventilation cowl:

  • It is important to ensure that the end of the ventilation pipe is protected from rain and snow, and prevents insects from entering the toilet. To achieve this, the toilet comes with a pipe cap that is equipped with an integrated insect net. This pipe cap should be used when the pipe end is horizontal and must be mounted with the screen upwards to ensure protection from rain and snow. The pipe cap fits both 50 mm and 1.5 inch pipes. 50 mm pipes go half way in and 1.5 inch pipes go all the way in. See picture below.


  • When the pipe end is vertical, the supplied ventilation cowl is to be used together with a pipe cap to ensure that rain and snow do not enter the pipe. Pipe cap and ventilation cowl are mounted together with the two supplied screws as shown below.  
  • The assembled parts are then mounted as pipe ends in the same way as shown in previous sections. It is also possible to use the ventilation cowl at a horizontal pipe end in more demanding conditions to ensure better protection against weather and wind.

Hooking Up your TINY to your Power Supply: 

  • If the toilet is to be mounted against a wall, a power cord must be connected to the toilet before it is mounted. After wall mounting, the connection is not accessible.
  • The Separett TINY must be connected to a power source. The toilet comes with a power adapter for 110–240 V and a 12 V battery cable. Regardless of the power source, the cord must be connected to the back of the toilet, at the marked input in the picture above. Make sure that the plug is properly connected.
  • Verify that the toilet is receiving power by checking that air is exiting the ventilation outlet.

Connect the toilet to the ventilation pipe and urine tube:


 Mounting your Separett TINY:

IMPORTANT! Connect the power cord to the toilet before mounting it. After mounting, you will not have access to the back of the toilet where the cable is to be connected.
  • The Separett Tiny is designed to be fixed to the floor or to the wall. For maximum stability, both options can be combined.

Floor Mounting:

  • To attach the toilet to the floor, use the supplied screw or other screw suitable for the purpose. There are two intended screw holes in the bottom of the toilet, the plastic in the middle of the hole is removed with a suitable tool.

Wall Mounting:

  • Use the following holes to mount the toilet to the wall.

Install the fixed fan filter:

  • The Separett TINY is continuously ventilated to ensure an odor-free bathroom as well as drying out the waste. To protect the fan from dirt and dust resulting from everyday use, there is a filter in the air duct. This filter is not pre-installed but must be installed on site as shown below. The filter should be cleaned regularly to maintain its proper functioning.
  • To install the yellow fan filter in the toilet, follow the steps below:
  • Place filter in the upward position as shown in this figure: 
  • Clip the top portion of the filter on the unit as shown in this diagram: 
  • Swing and clip the rest of the filter as shown on this diagram: 

 Place basket in the urine drain:

  • Place the supplied basket in the urine drain. The net ensures that no large objects enter the urine outlet. The basket is designed to perfectly fit a Separett Bio Drain Cleaner.


Separett Tiny Urine Diverting Toilet Maintenance:

  • The Separett Tiny should be cleaned with an environmentally friendly non-abrasive cleaner. This toilet is made of a strong, high-gloss polypropylene material that risks being scratched if an abrasive cleaner or scrubbing plate is used.
  • The fan must run continuously to avoid odors in the bathroom. Regularly rinse the filter in the fan duct with water to maintain good ventilation.

Separett Tiny Urine Diverting Toilet User Instructions:

  • Always sit down (do not urinate white standing or squatting). Sit a little further back than usual so that urine and solid waste are separated correctly.
  • The view screen will slide away once your weight is on the seat.
  • Toilet paper can be thrown in the same bin as the solid waste, but be careful to keep it away and out of the urine/drainage section.


Emptying of urine container (on the TINY with the holding tank):

  • For full-time use in a household of 2 people, the urine container should be emptied approximately 2–3 times per week. The toilet will signal when the urine container is full by illuminating the logo on the toilet in red. Once the light is on, the toilet can handle 1–2 uses, after which the container must be emptied. Open the top of the toilet to empty the tank. Make sure that the top is locked in its opened position before releasing it. Then follow the steps below:

  1. Make sure that the small yellow cap is screwed on tight and then screw the large yellow cap onto the urine container 
  2. Keep the caps on and lift the container out of the toilet. To facilitate lifting, use the transverse yellow handle on the container when lifting it. 
  3. Carry the container to the place where it is to be emptied. 
  4. Unscrew the small cap and keep the large one screwed on. 
  5. Empty the container by holding it firmly in the handle with one hand while holding the bottom of the container with the other. Now angle the container downwards and empty the contents from the small outlet. 
  6. When the container is empty, screw the small cap back on and make sure it is secured. 
  7. Place the container in the toilet again and make sure that it is correctly positioned. 
  8. Unscrew the large cap of the tank and place it in its designated storage location. 
  9. To close the top of the toilet, pull the top towards you until the latch releases. Then carefully close the top and make sure it closes correctly. To make sure that the container is correctly positioned, test to see if the upper part springs back when you press down on the front part of the seat. If nothing happens, the container is misplaced.

Emptying of solid waste:

The solid waste is collected in the waste container which is fitted with a compostable waste bag. For full-time use in a household of 2 people, the solid waste should be emptied approximately after 2 weeks of use. To do this, open the upper part of the toilet to empty the solid waste. Make sure that the top is locked in its opened position before releasing it, then follow the steps below:

1. Place the included lid on the container.

2. Lift the container by its yellow handle and pull it up out of the toilet.

3. Carry the container to where the waste will be handled.

Options for discarding the solid waste:

Option 1: Composted directly in an approved compost

Option 2: Incinerated directly in an approved incinerator

Option 3: Place it in a container and have it standing in “hibernation” for at least 12 months by following the steps below:

A) Place in an appropriate location outdoors, in a suitable container with a solid bottom.

B) Fill the container with a layer of soil (approx. 2 cm or 0,8”), make sure that the container is properly ventilated so that air circulates in the container.

C) Let sit for 12 months. The bacteria in the soil will break down the harmful organisms in the feces, rendering the waste harmless.

D) After the storage period, the contents can be composted in an ordinary compost, garden compost or buried in a compostable biodegradable bag.
