Buying Guide – How to Choose the Best Dometic RV Toilet
Selecting the right toilet requires balancing comfort, durability, and space constraints. This guide breaks down the critical factors to consider.
Bowl Material
Porcelain bowls are more durable and resistant to stains than plastic but add weight. Plastic bowls are lighter and cheaper but may stain or scratch over time.
Choose porcelain for long-term durability and plastic for weight-sensitive builds.
Seat Height
Standard residential chairs are 18 inches high while low-profile models are 13-5/8 inches. Height affects comfort and how easily you sit and stand.
Select based on your body type and RV floor space.
Flush Type
Gravity flushes are simple and reliable while macerator pumps offer versatility for remote installs. Spray flushes use less water for rinsing.
Gravity is best for standard setups while macerators suit complex layouts.
Mounting
Most Dometic units use a 2-bolt mount for universal fit. Check your existing rough-in measurements before buying.
Ensure the footprint matches your floor to avoid renovation work.
Water Efficiency
Water usage varies by model so look for designs that minimize fresh water use. Some use as little as one pint per flush.
Prioritize efficiency to reduce refills during dry camping.
Noise Levels
Soft-close lids and quiet flush mechanisms reduce noise which is important in shared spaces. Noise can disturb sleep if the bathroom is near sleeping areas.
Check reviews for noise feedback on specific models.
Ease of Cleaning
Rimless designs and non-porous surfaces are easier to sanitize. A cleanable toilet is critical for hygiene on the road.
Choose models with accessible areas to prevent grime buildup.
Budget
Prices range significantly from budget plastic models to premium porcelain ones. Set a realistic budget based on your travel plans.
Balance initial cost against expected lifespan.
How to Use and Care for Your Dometic RV Toilet
Always add water before flushing if using a manual foot pedal to prevent waste from sticking to the bowl. This routine keeps the bowl cleaner and reduces the need for scrubbing later.
Regularly inspect the seals and foot pedal for wear. Replacing seals annually helps prevent leaks and odors inside the RV bathroom.
Use RV-safe toilet paper to avoid clogging the valve. This simple habit maintains smooth operation and extends the life of your toilet.
Frequently Asked Questions
What is the difference between Dometic 400 and 300 series toilets?
The 400 series typically includes soft-close seats and modern flush designs while the 300 series uses older gravity flush mechanics. The 400 series often has better durability features like spray flushes.
How do I know which toilet fits my RV?
Measure your floor rough-in distance which is usually around 7.625 inches. Check the 2-bolt mount requirement and compare with the existing toilet footprint.
Can I replace a plastic toilet with a porcelain one?

Why is my RV toilet leaking?
Leaks usually come from worn seals around the base or the foot pedal. Replacing the seal kit can fix most leakage issues effectively.
How much water does a Dometic RV toilet use?
Efficient models use about one pint per flush. Some spray flush designs may use slightly more but maintain a cleaner bowl.
Is the Dometic toilet easy to install?
Most models are drop-in upgrades requiring basic tools. Ensure you have the right mounting kit and seal before starting installation.
