The Primo XL is our enlarged and upgraded version of the Original Outhouse using the same tried and tested design but a little larger and boasting our sunroof design, a hand wash basin, and incorporated saw dust box .


Our Outhouses can be fitted with a composting, long drop or flushing toilet even a urinal, theres more details below, and you simply select which you require at purchase.

Design, build and portability 

We wanted our Outhouse to be simple to use, portable, strong and environmentally friendly. The design harks back to the traditional outback or frontier outhouses and privy’s, this was something I was keen to keep the look and feel of by choosing the correct materials that would also fit with our sustainability brief.


The base of the Primo XL is constructed from thick reclaimed timber skids and a treated solid wood deck constructed in a pallet style, meaning it can sold and shipped nationwide or even across the world and be easily maneuverable once on site.

All our Primo models come with recycled plastic base,protectors keeping the timber off the ground.


The walls and roof structure, and the cladding are pressure treated FSC timber sourced from sustainably managed forests, this choice was made to ensure strength and reliable production. All our frames are screwed by hand for strength and accuracy, not nailed for speed. 

The door is made from treated tongue and groove shiplap, screwed and braced together. They are hung with strong UK made T-hinges and feature a reclaimed hardwood handle and locks inside and out. 


As well as being pressure treated the outside of the Primo XL Outhouse will receive an additional water based UV protective exterior finish all over. For an additional £75 you can select a colour of your choice.

All primo models comes with our sunroof option. The sunroof is an excellent addition to the Outhouse it transforms the space inside and reduces the need for lighting, making it a much nicer place to be. 


The Primo XL is wider than our other Outhouses giving you room for a sawdust/cover material box to the side of the toilet and a hand basin & tap with an antibacterial recycled plastic splashback. 


Eco friendly and sustainable


I’m sure by the time you’ve read to this point you will understand how passionate we are about the environment and the use of sustainable and reclaimed materials. You won’t find any ply wood or manufactured wooden board here!

Reworkshop are constantly striving to ensure all the materials, fixings, adhesives and coatings we use are as environmentally friendly as possible while still being fit for purpose. We genuinely feel our Outhouses are the greenest toilet units on the market.


Which toilet will you have in you Primo  XL Outhouse?

Composting toilet 27 litre


Our original design and still our most popular choice, the 27 litre flexi tub is easy to empty and gives enough capacity for a couple of days.

To empty you simply lift the toilet box lid and remove the flexi tub from inside the Outhouse.

The toilet box is constructed of FSC timber and clad with reclaimed wood, the lid is thick solid pine and treated with a wax oil. The Primo XL comes with an solid oak toilet seat.

The separator is adjustable and urine is piped out of the rear of the unit. We also supply a soak away vent to prevent smells coming back up the separator


Composting toilet 75 litre


If your after more capacity from your composting toilet this is the unit for you. This new design has a recycled plastic drawer at the rear which slides open making changing the container even easier. It comes as standard with a 75 litre flexi tub but has room for taller containers if needed.

The toilet box on the 75 litre version is the same as the 26 litre, which means you still have access to the container and the separator from inside the Outhouse for inspection.


Long Drop


The traditional long drop or pit latrine for all intents and purposes this looks exactly the same as our composting toilets but there is no collection or separation these toilets are simply positioned over a hole in the ground, inside the toilet box is a recycled plastic lined chute which protects the timber and is easy to clean.


Flushing toilet


If you have a sewer or septic tank conenection availible, you can of course have a flushing toilet installed in your Outhouse, these will come with all the interior connections already made for waste and clean water, with just the exterior connections needing to be made once on site.




Often over looked, but a urinal can be a very important toilet on a site, they take a lot of pressure off normal toilets, reduce queues and help prevent miss-use of composting toilets by male users.

Our Urinal Outhouses don’t require a water connection they simply need the waste pipe connecting to a soak away or drainage. The interior, walls and floor are partially lined with a recycled plastic protecting the timber and making cleaning easy.
