With this bundle you have all the components you need for your individual project.

Make a plan:

Now you just need to figure out how your DIY toilet should fit your space. Do you want to follow the Free DIY Throne plans? Just download them here for all the templates and a convenient list of things to buy at your local hardware store. 

The DIY Throne plans don’t fit your space, your style, or your design? No problem, it’s easy to design your own toilet! Some great inspiration can be found on our Instagram feed and in our case studies. 

With your DIY plan you can fit your Throne toilet in your van, your outhouse, customize it for weirdly shaped RV bathrooms, and even your personal height. 

Gather your supplies:

Tools like a jigsaw (to cut out the hole for the diverter) and circular saw (or have the individual pieces cut to size in your local hardware store), drill, pencil, and sanding paper. 

You might also need wood glue, silicone, and putty.

We recommend waterproofing the interior and exterior of the toilet. Accidents happen, and it’ll make cleaning so much easier and helps to extend the life of your DIY composting toilet. Examples of options to waterproof include metal flashing (we recommend aluminum because it’s easy to work with and to clean), plastic sheets, or waterproofing wood with Polyurethane or liquid rubberized coating (for the insides of your toilet).  

Keep it simple…

… to build, to maintain and to use.

Remember to keep your toilet easy to clean and maintain (check our blog post about mistakes to avoid when building your composting toilet). This includes filling screw holes, avoiding nooks, crannies, and hard to reach edges where possible. And, most important of all: Plan on how you want to empty both your liquids and your solids and build your toilet accordingly.
