Buying Guide – How to Choose the Best Dometic RV Toilet

Choosing the right RV toilet depends on your budget, available space, and comfort needs. This guide helps you understand key factors to make an informed decision.

Bowl Material

Most models use porcelain or heavy-duty plastic. Porcelain is durable and scratch-resistant, making it easier to keep clean. Plastic is lighter and cheaper but may wear faster over time.

Choose porcelain for long-term quality or plastic for weight savings and budget constraints.

Seat Height

Standard residential height is around 18 inches, while low-profile options are around 13 inches. Taller seats provide better comfort for adults, while lower ones suit compact spaces.

Select a height that matches the user's comfort and the available floor space.

Mounting Type

Universal 2-bolt mounts are standard for most RVs. This design allows easy upgrades from older models without major layout changes.

Check your current rough-in dimensions to ensure compatibility before buying.

Flush Mechanism

Gravity flush systems are simple and reliable, while macerator pumps offer more versatility for complex plumbing. Foot pedals or electronic handles control the flush.

Opt for gravity flush for simplicity or macerator for advanced plumbing needs.

Water Efficiency

RV toilets use limited water per flush, often just one pint. Efficient models reduce waste and extend your water supply between fill-ups.

Look for models with spray flush or rimless designs to save water.

Cleaning Features

Features like rimless bowls or spray systems make cleaning easier. Materials that resist stains and odors also save time on maintenance.

Prioritize easy-clean surfaces to keep your bathroom hygienic.

Noise Level

Soft-close seats and quiet flush mechanisms prevent noise. This is especially important in small living spaces where sound travels easily.

Choose models with soft-close lids for a quieter experience.

Price and Warranty

Prices range from budget-friendly to premium options. Ensure you understand what is included and check warranty coverage for peace of mind.

Compare features against cost to find the best value for your needs.

How to Use and Care for Your Dometic RV Toilet

To use the toilet effectively, press the foot pedal partially to add water and fully to flush. This helps maintain proper water levels and hygiene.

Regular cleaning with RV-safe solutions prevents odors and keeps the bowl fresh. Avoid harsh chemicals that might damage seals or plastic parts.

Check seals and gaskets annually to prevent leaks. If water leaks around the base, replace the seal promptly to avoid damage to your RV floor.

Frequently Asked Questions

How do I know if a Dometic RV Toilet fits my current setup?

Check the rough-in dimensions of your current toilet. Most Dometic models use a 2-bolt mount and fit standard 7.625-inch rough-ins. Ensure the floor clearance matches the new model requirements.

What is the difference between porcelain and plastic RV toilets?

Porcelain toilets are heavier but more durable and scratch-resistant. Plastic toilets are lighter and cheaper but may not last as long under heavy use. Choose based on your budget and durability needs.

How often should I replace the seal on my RV toilet?

Inspect the seal annually. Replace it if you notice leaks or odors. Using RV-specific toilet paper also helps prevent seal damage and prolongs its lifespan.

Can I install a Dometic toilet in a camper without a permanent bathroom?

Yes, portable options like the 970-Series are designed for this. They self-contain waste and do not require fixed plumbing. For permanent setups, check space and water line access.

What type of toilet paper is best for RV toilets?

Use RV-safe, biodegradable toilet paper that dissolves quickly. This prevents clogs in the macerator or holding tank. Standard household paper may cause blockages.

How can I prevent odors from my RV toilet?

Ensure seals are tight and clean the bowl regularly. Add holding tank treatments to neutralize odors. Using the right amount of water during flushes also helps.
