Porta Potti Thetford 365 Portable Toilet
The Porta Potti 365 offers a refreshed appearance with industry-leading performance and a rotating pour-out spout for convenience on water. Its self-contained design minimizes odors and leaks, a crucial feature when space and ventilation are limited aboard a boat. The unit combines portability with a practical flush mechanism and a compact footprint, making it a strong all-around choice for RVs, marine vessels, and travel setups on water.
Camco 2.6-Gallon Portable Toilet
Camco’s 2.6-gallon portable toilet focuses on on-the-go reliability with a detachable holding tank and a sealing side valve to lock in odors and prevent leaks. The unit includes a bellows-type flush system in a compact, lightweight package, plus a carry handle for easy transport. Its straightforward design is well-suited to boats, caravans, and camp setups where a dependable, simple solution is preferred.

The unit’s lightweight construction uses durable plastics, making it easy to move around on deck or in cabins. The 2.6-gallon tank size balances capacity with portability, a practical middle ground for small to medium boats, campers, and emergency ready rooms. Its design minimizes maintenance while maximizing on-water comfort.
Kohree 5.8 Gal Camping Toilet
The Kohree model lowers space pressure with an ergonomic diagonal seat and a 13″ long elongated bowl, closely mirroring a home toilet experience. The unit holds 5.8 gallons of waste and 3.2 gallons of fresh water, enabling multiple uses between empties. It supports up to 440 pounds and is constructed from high-density HDPE and PP for durability. The level indicator helps monitor when it’s time to empty, a crucial feature for maintaining onboard sanitation on boats.
Buying Guide
When choosing a portable boat toilet, consider capacity versus space. Larger waste tanks reduce emptying frequency but require more storage. Weight matters for deck handling and boat balance, so lighter options are beneficial on smaller craft. Look for durable materials like high-density polyethylene or ABS plastic to withstand marine conditions and repeated use.
Odor control is essential aboard a boat. Sealed valves, gasketed tanks, and venting strategies help maintain a fresh cabin. A stable, non-slip base prevents tipping in rough seas, and a secure locking mechanism ensures safety for all users. For families or mixed users, adjustable heights or seats designed for adults and children increase versatility.
Flush mechanisms vary. Bellows pumps are simple but may require more effort; pressurized or electric flush features save water and improve cleaning efficiency. Detachable tanks simplify cleaning and disposal, which is especially important on shore power, marinas, or locations with limited waste facilities. Finally, ensure the unit fits your boat’s storage footprint and does not interfere with seating, galley space, or cabin access.
In summary, balance capacity, weight, and ease of use. For compact boats, a 2.6-gallon system with a solid odor seal often suffices, while larger vessels or families may benefit from bigger waste tanks and ergonomic seats. Choose a model with durable construction, reliable seals, and a straightforward maintenance routine to ensure onboard comfort on every voyage.
