Buying Guide
What to consider when choosing a gravity-flush RV toilet
Height and rough-in: Look for 18–19 inches chair height to match home comfort, and ensure the rough-in (distance from the wall) matches your RV’s plumbing slots. Universal 2-bolt mounts simplify replacements.
Material and bowl design: Porcelain bowls are easier to clean and resist odors but add weight. Plastic bowls are lighter but may require more cleaning. Elongated bowls offer more comfort in tight spaces.
Flushing system: Gravity flush relies on water flow and pedal action. Some models offer adjustable water flow for efficiency. A soft-close seat reduces noise during travel.
Additional features: Hand sprayers, anti-stick bowls, and quick-seal replacements can influence maintenance. Confirm warranty terms and coverage duration for long trips.
Installation considerations: Check whether floor flanges are sold separately or included. Ensure compatibility with existing mounting footprints and space constraints in your RV bathroom.
Installation and maintenance tips
- Measure rough-in spacing and mounting footprint before buying.
- Verify that floor flanges or mounting hardware are compatible with your RV’s plumbing.
- Follow the manufacturer’s instructions for spring-loaded seals and purge cycles to maintain flush efficiency.
- Regularly inspect seals and gaskets to prevent leaks during travel.
