Buying Guide – How to Choose the Best Dometic RV Toilet

Selecting the right toilet depends on several factors including weight, materials, and installation requirements. This guide outlines the key elements to consider for your specific needs.

Bowl Material

Porcelain bowls offer superior durability and resistance to stains and odors. They are heavier and more expensive but ideal for long-term use. Plastic or polypropylene bowls are lighter and cheaper but may scratch easier.

Choose porcelain if you prioritize hygiene and longevity. Choose plastic if you need to minimize weight or reduce costs.

Seat Height

Standard residential height is around 18 inches. Low-profile models are about 13.6 inches. Taller users prefer 18 inches for comfort, while limited space might require a lower model.

Measure your bathroom space and consider the users to determine the best height for comfort and fit.

Mounting Type

Most models use a universal 2-bolt mount fitting standard rough-ins of 7.625 inches. Ensure your existing plumbing matches before buying. Portable toilets are self-contained and need no plumbing.

Check your floor layout to ensure the 2-bolt mount is compatible with your RV setup.

Flush System

Gravity flush is simple and reliable without power needs. Macerator pumps require electricity but allow flexible plumbing. Spray flush systems use less water while maintaining cleanliness.

Select gravity flush for simplicity. Choose macerator if you have complex plumbing needs.

Seat Features

Soft-close seats prevent slamming and add comfort. Wooden seats feel warmer than plastic. Position-lock hinges keep the lid up when needed.

Look for soft-close and lock hinges for improved daily usability and safety.

Water Efficiency

Models using one pint per flush help conserve fresh water. Efficient spray systems cover the bowl fully without waste. Check your water capacity before selecting high-usage models.

Prioritize water-saving designs if you plan long trips without hookups.

Space Constraints

Compact rear profiles save floor space in small bathrooms. Elongated bowls require more floor length but offer comfort. Measure dimensions before purchasing.

Account for both depth and width to ensure the toilet fits your layout.

Budget Considerations

Prices vary from affordable plastic models to premium porcelain units. Higher-end models add comfort and longevity. Determine your budget and prioritize features that matter most.

Balance cost against frequency of use to select the best value option.

How to Use and Care for Your Dometic RV Toilet

To use the toilet, press the foot pedal partially to add water and fully to flush. For soft-close models, lift the lid gently to avoid slamming. Ensure the bowl has enough water before using to prevent sticking.

Regular cleaning with RV-safe cleaners keeps the bowl hygienic. Avoid harsh chemicals that damage seals or porcelain. Inspect seals annually to prevent leaks. Replace seals if you notice odors.

When storing the RV for long periods, empty and clean the bowl. Add a small amount of water and seal the valve to prevent drying. This ensures the toilet remains functional for your next trip.
