Things to Consider When Looking for a Porta Potty 

Here are the most important things to consider when looking for high-quality portable toilets for boating:

Weight Bearing Capacity 

It would be best if you chose a toilet that can effectively support your weight without collapsing. Consider a model with a weight-bearing capacity of not less than 150 pounds.

But you can consider a model with a higher weight limit of up to 300 pounds if you are a heavy person. Make sure the bowl is large enough to accommodate your buttocks.

The seat needs to be considerably high for a home-like feel.

Flush and Waste Tank Capacity 

We can’t insist enough, but a Porta Potty with large tank capacities is the best. The flush tank should not be less than four gallons to get at least fifty flushes before a refill is needed.

A waste tank with a capacity of around five and a half gallons may last for several hours while you are in the water.

Flushing System 

You can choose a model with either an electric or manual flush system. With an electric flush, all you have to do to clean the mess is push a button.

A manual flush; on the other hand, needs to operate flush to clean the mess manually.

For this roundup, the winner is Thetford Porta Potti 365 Toilet.

This incredible potty is durable, portable, easy to use, and extremely easy and quick to clean. It is equipped with an ergonomically designed piston flush pump for ease of use.
