Buying Guide – How to Choose the Best Dometic RV Toilet

Selecting the right toilet involves considering material durability, water usage, and installation constraints specific to your vehicle layout.

Bowl Material

Porcelain bowls are more durable, stain-resistant, and easier to clean compared to plastic. However, plastic options are lighter, which helps reduce overall vehicle weight for better fuel efficiency.

Choose porcelain for long-term hygiene and plastic if weight savings are your priority.

Flush System

Gravity flush toilets are simple and reliable, using minimal water to clear waste. Macerator pumps grind waste for efficient disposal but require electricity and are more expensive.

Gravity systems are best for standard setups, while macerators suit larger rigs needing high efficiency.

Seat Height

Standard 18-inch seats offer residential comfort, while low-profile 13-inch seats suit RVs with limited ceiling clearance. Measure your space before purchasing.

Ensure the seat height matches your comfort needs and installation space constraints.

Mounting Style

Most Dometic models use a universal 2-bolt mount that fits standard RV rough-ins. This simplifies upgrades, replacing competitor units without layout changes.

Check your current rough-in size to ensure a seamless drop-in replacement.

Water Efficiency

Water conservation is critical in RVs. Look for models with foot pedals or flush options that let you control water usage per flush.

Efficient toilets help extend your fresh water tank life on the road.

Seat Features

Soft-close seats prevent loud slamming and add convenience. Position-lock hinges hold the lid up when needed, improving usability during daily use.

Prioritize these features for enhanced comfort and quieter operation.

Installation Options

Consider whether your RV requires through-the-floor or through-the-wall installation. Some models like the MasterFlush offer versatile mounting for custom layouts.

Verify installation requirements match your RV's bathroom structure.

Budget

Prices vary based on material and features. Budget-friendly plastic models cost less, while porcelain or macerator units are premium investments.

Balance cost with expected usage frequency and durability needs.

How to Use and Care for Your Dometic RV Toilet

To use the toilet correctly, press the pedal partially to add water before flushing. Then press fully to flush, ensuring waste is cleared without excessive water waste.

Regular cleaning involves wiping the bowl with RV-safe cleaners and avoiding harsh chemicals that could damage seals. Inspect the seals periodically for signs of wear.

Always use RV-specific toilet paper to prevent clogs. If you have a macerator system, run it with sufficient water and check the electrical connections regularly.
