How to Secure a CompoCloset Toilet in a Campervan, Motorhome or Boat
In short
You can secure a CompoCloset toilet by screwing it down through the four reinforced eyelets in its base, wedging wooden chocks under the side handles or looping a bungee cord over it. For a more permanent setup, you can mount it in a pull-out drawer. All three models share the same dimensions, so every method works for Cuddy, Cuddy Lite and the S1.
Curious about how to secure your CompoCloset toilet in your rig? We've got some ideas for you!
Simple Options to Secure Your CompoCloset Toilet
Some of the top ways to secure your toilet from CompoCloset based on our own experience and community feedback are:
- Screw it down
- Use wooden chocks
- Bungee cords
The best part? All of CompoCloset's toilet models are the same dimensions, so these methods will work with Cuddy, Cuddy Lite, and the S1 Sealing Toilet!
The video below goes into a bit more detail on these options:
Screw It Down
Best for permanent builds and rough roads. This is the option that stops the toilet moving at all.

- Clear it out: Remove the solids bin and the urine bottle so you can see the floor of the base.
- Find the eyelets: There are four reinforced eyelets moulded into the floor of the base. They're made for exactly this.
- Mark your holes: Put the base where you want it and mark your drill points through the eyelets.
- Screw it down: Use self-tapping screws that suit your subfloor.
Add large washers. Big penny washers spread the load across the eyelets, so the screw heads can't pull through the plastic when you're bouncing over rough ground.
The solids bin sits above the mounting points and comes out separately, so there's no mess and no risk of leaks.
Use Wooden Chocks
Best if you want your toilet held firmly in place on the road, but easy to lift out for cleaning or to free up floor space.

- Find the gaps: The base has built-in side handles, a finger pull at the front and a large recessed space at the back.
- Cut blocks to fit: Cut small wooden blocks that match those gaps.
- Screw the blocks to your floor: Position them so they line up with the handles and the rear recess.
- Lower the toilet on: The blocks sit inside the toilet's own indents, so it can't slide forward, backward or side to side. You can still lift it straight up and out in seconds.

Bungee Cords
Simple and removable. A good fit for motorway driving and light trails.
- Fit two sturdy metal eyelets to the floor, or to the cabinet walls on either side of the toilet.
- Loop a heavy-duty bungee cord over the top of the unit and hook it into the eyelets.
- Make sure it's tight enough to hold the toilet down against the floor, so it can't shift when you brake or accelerate.
Which Option Is Right for You?
- Screw it down: Full-time builds and heavy off-road use. You'll need self-tapping screws and large washers.
- Wooden chocks: Taking the toilet out often, while keeping it stable on the road. You'll need wood blocks and screws.
- Bungee cords: Weekend trips and lighter travel. You'll need two eyelets and a heavy-duty bungee cord.
