This guide explains how to plan and install a compatible Fix-a-Potty™ toilet bracket or sliding bracket kit in a campervan, motorhome or RV.
Fix-a-Potty brackets are available for compatible 10L and 20L toilets. Match the bracket to the exact toilet size and shape before drilling any holes.
Important certification check before you begin
New Zealand's current self-containment rules require the toilet to be fit for purpose, installed in accordance with its design, permanently fixed with its base rigidly mounted, and arranged so the base does not need to be removed to empty human waste.
A bracket on its own does not guarantee certification. Confirm the complete toilet, bracket and emptying arrangement with your self-containment certification authority or vehicle inspector before installation. This is particularly important for any portable-style toilet that must be separated or removed for emptying.
Choose the right Fix-a-Potty setup
- 10L Fix-a-Potty™ securing bracket for a compatible 10L toilet.
- 20L Fix-a-Potty™ securing bracket for a compatible 20L toilet.
- 10L sliding bracket and runner kit where the toilet needs to slide out for use.
- 20L sliding bracket and runner kit for the larger compatible toilet.
Tools and hardware
- Tape measure, square and marker.
- Drill and suitable drill bits.
- Spanners or socket set.
- Vehicle-appropriate bolts, load-spreading washers and lock nuts.
- A backing plate where the vehicle floor or cabinet structure needs reinforcement.
- Suitable sealant for any drilled vehicle-floor penetrations.
Mounting hardware depends on the construction of your vehicle and is not included.
Installation steps
- Check compatibility. Place the toilet in the bracket before installation. It should seat correctly without forcing or distorting the toilet body.
- Choose a usable position. The toilet must be usable inside the vehicle with adequate head, shoulder and elbow room. Check that the lid opens and that the approved waste-emptying method remains accessible.
- Check below and behind the mounting area. Locate wiring, fuel lines, water pipes, brake lines and structural members before drilling.
- Mark the bracket position. Set the bracket square to the cabinet or vehicle wall, then mark every fixing point. For sliding runners, mount both runners parallel and level so they travel freely.
- Drill and protect the holes. Drill suitable pilot holes. Seal exposed timber or metal edges and any floor penetrations where required.
- Bolt the bracket securely. Use fixings suitable for the vehicle construction. Load-spreading washers or a backing plate help prevent the fixings pulling through thin flooring or cabinetry.
- Fit and lock the toilet. Engage the toilet fully with the Fix-a-Potty bracket. Fit every supplied retaining part and confirm the toilet base cannot lift, slide or rotate during normal use or travel.
- Check sliding runners. If fitted, operate the runners several times and confirm the assembly locks securely in both its stored and usable positions.
- Verify emptying access. Demonstrate the toilet's intended emptying method without undoing the vehicle mounting or removing the rigidly mounted base.
Final checks
- Sit on the toilet carefully and check for movement or flexing.
- Confirm all nuts are tight and cannot loosen through vibration.
- Check that cabinet doors, Hide-a-Potty covers and sliders do not interfere with the toilet.
- Reinspect the installation after the first trip and periodically thereafter.
- Ask your inspector to assess the complete arrangement before relying on it for certification.
Official references
For the current requirements, refer to the Self-Contained Vehicles Regulations and the Plumbers, Gasfitters and Drainlayers Board vehicle inspection guidance.
This guide is general installation information. Final self-containment approval depends on the complete vehicle, the exact toilet design and the certification authority's inspection.
