Buying Guide – How to Choose the Best Dometic RV Toilet
Selecting the right toilet involves balancing comfort, weight, and installation needs.
Bowl Material
Porcelain offers better scratch and stain resistance than plastic. It feels more luxurious and cleans easier but adds weight. Plastic is lighter and cheaper but may degrade over time.
Choose porcelain for durability or plastic for weight savings.
Seat Height
Standard residential height is 18 inches for comfort. Low-profile options around 13.5 inches fit smaller spaces. Consider who uses the RV most often.
Opt for standard height unless space limits installation.
Flushing Mechanism
Gravity flush systems are simple and water-efficient. Macerator pumps offer more installation flexibility but are pricier. Spray flushes cover the bowl better.
Select gravity flush for simplicity or macerator for flexibility.
Seat Features
Soft-close seats prevent slamming and add comfort. Some models offer position-lock hinges for easier cleaning. These features improve usability and satisfaction.
Look for soft-close mechanisms for a better experience.
Universal Fit
Most models use a standard 2-bolt mount for easy replacement. Check your rough-in dimensions to ensure compatibility. This reduces installation complexity and costs.
Ensure the model matches your RV's existing rough-in.
Water Efficiency
Efficient models use about one pint per flush. Macerator toilets often save more water with dual flush options. Less water means smaller waste tanks and fewer dumps.
Prioritize water-saving features for longer trips.
Installation Type
Fixed toilets bolt directly to the RV floor or wall. Portable models are temporary and require no plumbing. Choose based on your RV's setup.
Install fixed units for permanent setups or portable for flexibility.
Budget Considerations
Prices vary from under $200 to over $1,500. High-end models offer porcelain and electronics. Entry-level models use plastic and simpler mechanics.
Match your budget to long-term comfort needs.
How to Use and Care for Your Dometic RV Toilet
Always keep enough fresh water in the tank to ensure proper flush function. Check the water level regularly to prevent dry seals.
Use RV-safe toilet paper that dissolves quickly in water. Avoid standard paper to prevent clogs and tank buildup.
Clean the bowl weekly with non-abrasive cleaners. Inspect seals annually for leaks and replace as needed.
Frequently Asked Questions
Are all Dometic RV toilets easy to install?
Most models feature universal 2-bolt mounts compatible with standard RV rough-ins. However, plumbing connections and floor types can vary. Professional help may be needed for wall installations.
How much water does a flush use?
Standard gravity models use about one pint per flush. Macerator models with dual flush options save even more. Always check specs to optimize tank capacity.
What is better plastic or porcelain?
Porcelain is more durable and scratch-resistant but heavier. Plastic is lightweight and cheaper but may stain over time. Your choice depends on weight limits and budget.
Can I use regular toilet paper?
No, only use toilet paper designed for RVs that dissolves fast. Regular paper can cause clogs and tank issues. This protects your plumbing system.
How do I fix a leak?
Leaks usually come from worn seals. Inspect seals first and replace if damaged. Ensure proper tightening of bolts and plumbing connections.
Is a macerator worth the cost?
Macerators allow versatile installation and save space but cost more. They are best for complex setups needing through-wall connections. Evaluate if the features justify the price.
