10 Best Cassette Toilet Rv 2025 in the United States

The SEAFLO Residential Height Camper/RV Toilet is designed to bring the comfort of home into your RV with its standard 18.5-inch height and an oversized, elongated bowl that helps with ease and cleanliness. Its dimensions (approximately 17.8” x 15.3” x 18.4”) make it compact enough for most camper spaces without feeling cramped. The gravity flush system uses tri-directional nozzles to deliver a strong, efficient flush. This type of flush is simple and reliable, though it relies on gravity and water volume, so it may not be as powerful as electric or pressure-assisted models. You operate it with a foot pedal, which adjusts water flow, making flushing hands-free and convenient. The bowl’s smooth, anti-stick surface reduces mess and splash-back, which makes cleaning easier—an important feature for RV use.

The seat has a soft-close mechanism, preventing loud slams during travel. Made from durable yet lightweight polypropylene plastic, the toilet balances sturdiness with portability, though plastic may feel less solid compared to porcelain. Installation is straightforward with included mounting bolts, but note that the floor flange is sold separately, so you’ll need to get that for a complete setup. Maintenance should be simple thanks to the design and materials, and the four-year warranty offers reassurance about durability. This toilet is well suited for RV owners wanting a reliable, comfortable, and easy-to-clean option without complex plumbing or electric parts. If you need a more powerful flush or integrated waste tank, you might want to explore other models.

The Dometic 310 Standard Toilet is a well-designed option for RV owners looking for something lightweight and efficient. It measures about 15 inches wide, 15 inches deep, and 33 inches tall, making it a standard size that fits most RV setups thanks to its universal fit. Its standout feature is the pressure-enhanced PowerFlush system, which uses only about 1 pint of water per flush—this helps conserve water, an important factor for camping and travel.

The slow-close seat cover is a nice touch, preventing noisy slams and adding to long-term durability. Built from a combination of wood, ceramic, and plastic, the toilet balances strength with manageable weight at around 23 pounds. The ergonomic seat height and shape improve comfort during use. Installation should be straightforward due to its universal design, and the simplified build likely makes maintenance easier.

If you want a reliable, water-saving RV toilet that offers comfort and quiet closing, the Dometic 310 is a solid choice and worth considering.

The Dometic 310 Standard Toilet is designed specifically for RVs, making it a solid choice for those looking for a reliable and efficient toilet system. One of its standout features is the pressure-enhanced 'PowerFlush' mechanism, which allows for effective cleaning of the bowl using very little water—only about a pint per flush. This water efficiency is a significant plus for RV users, who often have limited water supply. Additionally, the lightweight design and universal fit make installation straightforward for most RV setups.

User comfort is another priority with this toilet. The ergonomic seat height and oblong bowl shape ensure that it’s comfortable to use, while the slow-close seat cover minimizes noise and potential damage from slamming.

However, the Dometic 310 has a few considerations to keep in mind. At 41 pounds, it may be heavier than some other portable options, which could be a downside for users prioritizing weight. Although ceramic construction adds durability, it can also make the toilet more prone to cracking if not handled carefully during installation or transport. Furthermore, while the toilet is designed for ease of operation, some users may still find the learning curve a bit steep if they are unfamiliar with RV toilets.
