Dometic 310 Standard Toilet - Efficient RV PowerFlush

In this review of the Dometic 310 standard toilet we look at whether this full-size, lightweight RV toilet lives up to its practical claims. The bottom line: it is best for RV owners who want a compact, durable porcelain-style bowl with a water-saving, pressure-enhanced PowerFlush system and a quiet slow-close seat. Installation is straightforward and maintenance is simple, so anyone replacing an older RV toilet or upgrading from lighter plastic models will appreciate the combination of sturdy construction and efficient flushing performance.

Key Features

• Innovative design: A full-size but lightweight construction makes the toilet suitable for modern RVs where weight and space matter while still offering a comfortable bowl shape.
• PowerFlush rim wash: The pressure-enhanced flushing system clears the bowl quickly and effectively, reducing the need for multiple flushes.
• Water efficiency: Able to flush with as little as 1 pint of water, it conserves fresh water on the road and lowers waste tank frequency.
• Slow-close seat cover: The new slow-close seat prevents slamming and reduces wear, giving a quieter, more durable experience.
• Comfortable ergonomics: An ergonomic seat height and oblong bowl shape provide more comfortable sitting than many compact RV toilets.
• Universal fit: The design allows installation on most RVs and uses a mix of wood, ceramic, and plastic components for longevity.

Who It's For

The Dometic 310 is ideal for RV owners replacing a worn or flimsy toilet who want a balance of weight savings and durability; it suits those who value a water-efficient PowerFlush and a quiet slow-close seat. It also fits well for owners upgrading from older model toilets who want easier cleaning and a more comfortable bowl shape.

It is less suited to people who need a specialized high-capacity marine toilet or those who have unusual flange or floor-mounting requirements without modification. Anyone expecting a heavy ceramic residential unit should note the emphasis on lightweight RV-friendly construction rather than full residential heft.

Pros & Cons

• Slow-close seat cover reduces noise and wear compared with standard lids.
• Easy installation and maintenance make it a practical replacement for many RVs.

Cons

• Some owners report mixed experiences with leakage, so careful sealing and correct installation are important.
• The universal fit may still require adjustments for nonstandard RV floor or flange layouts.
