10 Best Marine Toilets 2025 in the United States

The Thetford Aqua-Magic® VI High Profile marine toilet is a solid choice for RV owners looking for a practical and reliable toilet solution. It features a straightforward pedal flushing mechanism where pressing halfway adds water and a full press flushes the toilet. This system is easy to use and helps control water usage efficiently. The toilet’s design includes an improved mounting system with bolt slots, making installation relatively easy even for those who may not be particularly handy.

Additionally, it comes with a residential-sized SloClose seat and cover, providing a more comfortable and familiar experience for users. The deep bowl design is also a plus, offering more space and a similar feel to household toilets, which can be a significant comfort for travelers. However, a notable drawback is the absence of an included hand sprayer, which some users might find beneficial for extra cleaning convenience.

The toilet is constructed from polypropylene, making it lightweight at 10.4 pounds and manageable for most RV settings with dimensions of 17.88 inches deep, 15 inches wide, and 17.75 inches high. The white color, while classic, may show stains more easily in a marine environment. This toilet is best suited for RV owners seeking easy installation and maintenance with a comfortable, deep bowl, although the lack of a hand sprayer might be a point to consider.

The Dometic 302320081 320 Series Standard Height RV Toilet is designed with a full-size residential style wood seat and a deep vitreous ceramic bowl, offering durability and a comfortable experience. With dimensions of 22 inches deep, 14.75 inches wide, and 19.75 inches high, this toilet fits well in various spaces while maintaining a standard height for user convenience. One of its standout features is the efficient water usage, requiring only one pint per flush, which is beneficial for conserving water on a boat or RV.

The ergonomic foot pedal is intuitive, allowing users to add water by partially pressing it or to flush fully by pressing it completely. The gravity flush system is simple and effective, but it may not be as powerful as other types of flush mechanisms. The rim design helps prevent spills, adding to its practicality. On the downside, the 43-pound weight might make installation a bit challenging, especially for individuals without assistance. Additionally, while the toilet does not come with a holding tank, this means you will need to ensure compatibility with your existing tank or purchase one separately.

Maintenance-wise, the ceramic bowl is easy to clean, though the wooden seat may require some extra care to maintain its condition over time. This product is ideal for those seeking a durable, comfortable, and water-efficient marine or RV toilet with a residential feel.
