Buying Guide – How to Choose the Best Dometic RV Toilet

Selecting the right toilet involves weighing material, dimensions, and features against your travel habits.

Bowl Material

Porcelain bowls offer durability, stain resistance, and a premium feel similar to home fixtures. Plastic bowls are lightweight and budget-friendly but may scratch more easily over time.

Choose porcelain for long-term use and plastic for weight savings.

Height Profile

Standard height toilets are 18 inches tall while low-profile options are about 13 inches. Standard models are more comfortable for adults while low-profile ones save space in smaller RVs.

Consider your space constraints and comfort needs before deciding.

Mounting Type

Most Dometic models use a universal 2-bolt mount to fit standard rough-ins. Always measure your existing RV rough-in distance to ensure a drop-in upgrade without layout changes.

Verify rough-in measurements to avoid installation issues.

Seat Features

Soft-close seats prevent slamming and add a residential touch. Some seats also have position-lock hinges to hold the lid up when needed for convenience.

Look for soft-close mechanisms for quiet and comfortable use.

Flush Efficiency

Gravity flush systems are reliable and efficient while macerator pumps offer flexible installation. Water usage varies with models using as little as one pint per flush.

Prioritize water-efficient models if you camp off-grid often.

Installation Space

Compact rear profiles allow installation in tighter layouts freeing up floor space. Measure your bathroom width and depth to fit larger models like the 420 properly.

Check dimensions carefully to ensure the toilet fits your bathroom.

Maintenance Needs

Porcelain surfaces are easier to clean than plastic which can harbor odors. Look for models with DIY seal replacement options to simplify maintenance on the road.

Choose designs that simplify routine cleaning and repairs.

Budget Considerations

Premium models cost more but offer enhanced durability and comfort. Budget models are lightweight and efficient but may lack premium features like porcelain bowls.

Balance your budget with your long-term usage expectations.

How to Use and Care for Your Dometic RV Toilet

Always use RV-friendly toilet paper that breaks down quickly to avoid clogging your holding tank or waste lines.

Clean the bowl regularly with non-abrasive cleaners to maintain the surface integrity and prevent odors from building up.

Lubricate the seals periodically to ensure a watertight seal and prevent leaks during your travels.

Frequently Asked Questions

Can I replace my old RV toilet with a Dometic model myself?

Yes, many Dometic models feature a universal 2-bolt mount that simplifies DIY replacement. Ensure your rough-in measurements match to avoid needing custom plumbing modifications.

Is a porcelain toilet better than plastic?

Porcelain offers better durability and stain resistance but adds weight. Plastic is lightweight and budget-friendly but may scratch more easily over time.

What is the rough-in size for these toilets?

Most models fit standard RV rough-ins of 7.625 inches or greater. Always measure before buying to ensure a proper fit in your specific bathroom layout.

Do these toilets require electricity to operate?

Most models operate on gravity flush systems that do not require electricity. Some premium models with electronic handles or macerator pumps need a power source.

How often should I replace the seals?

Regular lubrication extends the life of seals but they should be inspected annually. Replace them if you notice any leaks or odors around the base.

Can I use regular toilet paper in an RV toilet?

Use RV-friendly toilet paper designed to break down quickly. Standard paper may not dissolve properly and can cause clogs in your holding tank.
