Buying Guide – How to Choose the Best Dometic RV Toilet

Choosing the right Dometic toilet depends on your budget, bathroom dimensions, and whether you prioritize weight or luxury features.

Bowl Material

Porcelain bowls offer superior durability and stain resistance but add weight. Plastic bowls are lighter and cheaper but may show scratches over time.

Choose porcelain for long-term durability and plastic for weight savings and budget efficiency.

Bowl Shape

Round bowls are standard and save space, while elongated bowls offer extra seating comfort. Consider your bathroom width before deciding.

Opt for elongated shapes if space allows for better comfort.

Seat Height

Standard height seats are 18 inches, while low-profile models are around 13 inches. Measure your ceiling clearance to avoid installation issues.

Select low-profile models for RVs with height restrictions.

Flush System

Gravity flush systems are reliable and efficient. Macerator pumps offer versatility for tank placement but are more complex and costly.

Stick to gravity flush for simplicity and reliability.

Water Efficiency

Look for models with dual-action pedals to control water usage. Efficient rinsing saves freshwater tanks during off-grid camping.

Prioritize models with adjustable water features.

Mounting Type

Universal 2-bolt mounts fit standard RV rough-ins. Ensure your new unit matches your existing plumbing footprint.

Check your current toilet mounting before purchasing.

Seat Features

Soft-close seats prevent slamming and add comfort. Some models include position-lock hinges to keep the lid up.

Invest in soft-close seats for better durability and noise reduction.

Installation Complexity

Drop-in upgrades simplify replacement without major plumbing work. Macerator models may require professional installation.

Pick drop-in models for DIY-friendly upgrades.

How to Use and Care for Your Dometic RV Toilet

Always add water before flushing to prevent waste from sticking to the bowl. Use the foot pedal to add a small amount of water first.

Keep the seal lubricated with silicone to maintain a tight seal and prevent odors from escaping into the cabin.

Clean the bowl regularly with non-abrasive cleaners to avoid scratching the surface. Regular maintenance ensures long-term performance.
