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 SereneLife RV Toilet is designed to fit well in small spaces such as RVs, trailers, and boats, thanks to its compact size (about 15 x 20 x 19 inches) which makes it a practical choice when space is tight. It uses a foot pedal to add water and flush, which is simple and convenient, and the toilet uses only 0.5 liters of water per flush, helping conserve water without sacrificing cleaning power. The leak-proof and odorless seal keeps unpleasant smells and leaks at bay, which is important for comfort and hygiene in a mobile environment.

Made from high-density polyethylene, it's sturdy and resists stains, making cleaning easier. Installation is straightforward with included kits, and the floor-mounted setup should suit most RV layouts. The soft-close lid adds a quiet, comfortable touch, and the hand sprayer is a useful extra for personal hygiene. Although it is lightweight (around 15 pounds), which enhances portability, it may not feel as solid as heavier models. Maintenance is user-friendly, but as with most cassette toilets, regular care and proper emptying are necessary to avoid any issues.

This toilet represents a solid choice for anyone seeking a reliable, water-efficient, and space-saving toilet solution for their RV or boat, especially when quick installation and odor control are priorities.
