Buying Guide – How to Choose the Best Dometic RV Toilet

Choosing the right toilet involves considering several factors to ensure it meets your travel needs and RV specifications.

Bowl Material

Porcelain bowls are durable and resist stains well, making them ideal for long-term use. Plastic bowls are lighter and more affordable but may scratch easier.

Consider your travel frequency and budget when selecting between porcelain and plastic options.

Seat Height

Standard height toilets around 18 inches mimic residential comfort, while low-profile versions save vertical space. Ensure the height suits all household members for ease of use.

Select a height that balances comfort with your RV's ceiling clearance and layout constraints.

Mounting System

Universal 2-bolt mounts simplify installation and allow replacement of older models without major changes. Check your floor's rough-in dimensions before purchasing.

Verify that the mounting system matches your existing setup to avoid costly modifications.

Flush Mechanism

Gravity flush toilets use water weight to clear waste efficiently. Macerator toilets use pumps for stronger waste processing but cost more.

Choose a flush type that aligns with your water conservation needs and plumbing capabilities.

Weight

Lightweight plastic models reduce overall RV weight, improving fuel efficiency. Heavier ceramic or porcelain models add stability but increase load.

Factor in your vehicle's weight limits when deciding on material density.

Seat Features

Soft-close seats prevent noise and wear, adding a touch of luxury. Check for hinges that allow easy cleaning or lid locking features.

Look for seat features that enhance comfort and hygiene for daily use.

Installation Type

Fixed toilets require permanent floor mounting, while portable units offer flexibility. Consider your RV's plumbing setup and whether you can install fixed plumbing.

Choose installation types that match your vehicle's plumbing infrastructure and your mobility needs.

Maintenance

Simple designs are easier to clean and repair. Consider availability of replacement seals or parts for long-term maintenance.

Prioritize models with accessible parts and easy-to-clean surfaces to reduce upkeep time.

How to Use and Care for Your Dometic RV Toilet

Flush the toilet by pressing the pedal fully to clear waste. Add water as needed for cleaning. Keep the lid closed when not in use to contain odors.

Regularly inspect seals and valves to prevent leaks. Clean the bowl with mild cleaners to protect porcelain or plastic surfaces.

When winterizing, drain the tank properly to prevent damage. Store spare parts like seat hinges or seal rings for quick repairs.
