To flush, I just have to press it again. It’s as easy as one, two, three! Unlike any other toilet models, this one provides the best comfort and luxury that I have ever experienced in marine toilets.

However, no matter how fine a product is, we should always expect a setback to come with it. In this case, this model is expensive compared to standard toilets, so it’s not the best choice if you’re on a budget. This is not a problem for me, since this product still does its job with supreme quality.
  • Comes from a reliable brand
  • It comes with a powerful 240-watt pump and 12-volt dc
  • Magnetic motor and ball compartments for powerful discharge
  • Guarantees to save both of your water and power consumption

If you think that I’m done with all its useful features, think again! All components come with a dry washing option and are attachable overhead or underneath the waterline.

It’s a good quality marine toilet offered at a fair price. The only minor setback of this new model is that its bolt shape has changed compared to the older Superflush, so you won’t be able to reuse old bolts. I have to do further mechanical work so that I can attach the new base correctly. It’s just a minor change, however. The product is still top-class for me.

This self contained marine toilet is one of the most reliable units a seafarer could ask for. Its effortless installation attracts a practical sailor as he can assemble this head easily.

I love the outstanding customer service of this self-contained marine toilet brand. It is positively unparalleled compared with any other company as they offer a five-year warranty on all of their products.

It may be the right product, but let me tell you its only setback that I find tedious. Discharging the main compartment is a pain in the back as it requires constant emptying every 1.5-2 weeks. The waste storage is a little hefty to the point that it becomes hard for a single person to do the waste disposal.
  • This self-contained toilet is highly convenient to install
  • Does not produce any unwanted odor and pungent smell
  • Comes with little maintenance, equipped with high versatility

Besides, I love its waste drying and diverting feature that keeps my compartment clean and odorless. It comes with a rapid fan, too, which significantly aids in air circulation and assists efficient venting of up to 20 feet around the room.

This product comes with ten compostable bags and one waste container with a cover to ensure you a clean and more organized experience. It also has a child seat that makes your toddlers more comfortable.

We can never deny that every product comes with downsides. In this case, the manufacturer will not accept returns once the toilet’s already set up.

I also like its large detachable holding tank as it has a whopping 5.3-gallon of storing capacity. Plus, there’s another 4 gallons for the flush tank. You can never go wrong with this model.

Also, it comes with a 19-inch gliding lid valve that effectively caps in odors and prevents waste leakage. With its decisive pumping flush action, the toilet’s internal surface will be properly sanitized. Cleanup will also be more manageable, thanks to its swivel dumping elbow that makes waste removal possible in a flash.

I appreciate how lightweight this product is. This feature makes it highly portable and convenient to bring on all of my camping and road trips. Its patented design is also a plus, as I have rarely seen such a good and fully functional product that perfectly meets my needs. If you’re looking for a reliable toilet, this one’s arguably the best choice.

No matter how good this product is, you have to make sure that it does not build up enough pressure. Make sure to open it before you go to avoid splashes when you flush. Otherwise, you may get filthy waste all over your place. Aside from that, I never had any other issues with this product.
  • Made from abs resin material, fully furnished with a patented design
  • Detachable holding tank comes with a vast storage capacity

I love its large capacity scrounger pump that efficiently grinds up waste. This feature makes the pumping action more convenient and quicker.

As mentioned above, I also like this product because it comes with a handy push control flush button. After using this porta potty, I only have to push a single button to wash it all away. There are no more hassles on my part.

Adding to that, it is also convenient to clean. I don’t have to spend hours trying to scrub this unit, which is far different from the usual ones.

Moreover, it comes with a 360mm x 445mm x 352mm dimension, a considerably portable size for marine toilets.

What’s more, the slow closing motion seat of this unit adds a bit of delicateness. With this function, I can use the toilet for a more extended period and minimize product damage due to irresponsible handling of the head’s closing seat.

I appreciate the product. However, the company’s response to specific queries can be a bit off. Most of the time, they become unresponsive, which can be disappointing. It tires me to wait for months just to have my concern answered. Nevertheless, it’s still a good and long-lasting product for me.
  • Powerful macerator pump makes cleaning and flushing easier
  • Convenient to clean
  • Is a considerably portable marine toilet
  • Comes with a slow closing seat to prevent damages from impact
  • Handy push control flush button makes this toilet more convenient
  • The company tends to be unresponsive to concerns and queries
This marine toilet is a suitable option if you want a long-lasting one. Its minimalistic design is also something to die for.

What is Marine Toilet and How Does It Work


A manual marine or electric marine toilet is a tool to help you relieve yourself on board. It flushes out the waste into a holding tank to be discharged later on.

It uses seawater or freshwater, depending on the boat’s surrounding area, to manually wash out sewage into a holding tank.

Types of Marine Toilets

More and more options for a marine toilet have come into existence, such as electric marine toilets, composting toilets, and manual marine toilets. I will discuss the two most famous types of marine toilets with different waste storage options, so check them out.

Composting toilets is the first type of marine toilet that I’ll talk about. It is odorless, making it more favorable to the majority of people. It comes with two containers intended for urine and solid wastes and works by allowing oxygen to dry and compost the waste.

On the other hand, electric marine toilets are convenient as they remove the need to cleanse the bowl through a hand pump. Electric marine heads usually have a built-in macerator as well, which efficiently grinds waste before dismissing it into the holding container.

It’s up to you if you prefer electric marine toilets with built-in macerator or composting heads.

Benefits and Drawbacks of Using Marine Toilet


An electric marine toilet is easy to use, since flushing only requires a push of a button. However, it might take some trial and error to know how long you should push the button, and doing it wrong might block the pipes.

Composting toilets, unlike electric ones, use no energy. They also come with minimal maintenance, as you won’t have to worry about joker valves or thru hulls. On the downside, when used the wrong way, composting toilets can result in bug infestations.

As for manual toilets, they are budget-friendly but prone to clogging if used incorrectly.

Buyer’s guide

If you’re looking for reliable electric marine toilets or those with a manual pump in town, check out my reviewed products above and see what suits you the best.

Heads from JABSCO, RARITAN, JOHNSON PUMPS, and CAMCO are famous for their consistent quality. These mentioned brands are the most famous manufacturers of first-class and comfortable composting toilets you’ll ever see in the market.

Care and Maintenance

A high-quality electric marine toilet does not take up too much of your time just to clean it up.

It would not hurt if you equip yourself with the knowledge to clean a marine toilet. This section will share all the necessary steps in keeping heads squeaky clean and in top shape.

Clean the lines by washing them with a nip of white vinegar monthly. You can rinse the unit gradually, giving it a pump from time to time. The slightly acidic substance effectively softens fresh scale in the head and water tubing. When the vinegar passes through the heads’ sanitation systems, it would be best if you pump a gallon of freshwater to flush the lines thoroughly.

The next maintenance care is lubrication. Lubricating is a breeze, too. If you want to retain the pump’s smooth operation, the only thing you have to do is to follow up your scheduled vinegar wash with a dose of oil. The top option is a lubricant ideal for marine bowls, but you can also use mineral oil if it’s not readily available.

Frequently Asked Questions


Who makes the top-rated marine toilet?

Several brands make high-quality heads, but JABSCO and RARITAN fight for the best manufacturer spot. Other brands such as CAMCO, NATURE’S HEAD, and THETFORD also stay competitive.

However, it is purely up to the user’s preference, as I prefer JABSCO to RARITAN. Fret not, though. This article ensures that you’ll have your ideal head that perfectly suits your taste.

Can you poop in a marine toilet?

Of course. Marine heads are a convenient tool to discharge your waste when traveling. A composting head is a go-to pooping station that relieves your discomfort and makes you feel at home during your adventure trips in the country, even without an ample supply of water along.

How does a marine macerator toilet work?

A marine macerator works similarly to the macerators of a regular head. After you do your thing, simply use a push-button or a knob switch to wash out the waste. The process includes the bowl’s water filling while it flushes.

Your waste, such as toilet paper, then goes through a macerator that dissolves it. The next step involves hose pumping into a holding tank, where waste can be released into the appropriate places. Keep an eye on no discharge zones where you cannot dump sewage, whether it’s treated or not. Make sure to have enough water for a quick flush.

What is a sea toilet on a boat?

A sea head or marine head can be attached to vessels. It removes human waste and toilet paper by washing it out directly into a holding tank to be emptied onshore.

Porta potty vs. marine head: What’s the difference?

A porta potty offers convenience and simplicity to the user. Besides that, it is also well-known for its affordability and energy-saving capabilities.

Its simple process of fill-and-dump dramatically differs from a fully-plumbed marine head, which usually involves the installation of tubes, valves, and through-hulls. Make sure to have ample water supply for these two types, though.

How to set up and use?

Like heads at home, a marine tank doesn’t require an engineering course for its installation and usage. It promotes user-friendliness that makes it accessible for you and your friend. Make sure that you always have an ample supply of water for functionality tests in this installation.

After doing your business, the only thing you’ll have to do is to flick the switch. This process lets you pump freshwater or seawater into the toilet bowl. The next thing to do is to toss the switch reversely, allowing you to drain the bowl out. For electric toilets, a simple press of a button will do.

Where can I buy?

You can have your very own marine toilet by browsing through Amazon. This is the best go-to platform when you’re looking for a low-profile marine head. If you want a reliable product, browse through Amazon and find the best one for yourself!


A marine toilet with a tank is a worthwhile investment that instantly adds value to your sailboat. Having one makes your trip more convenient and relaxing. I hope you found the right one for you in this guide. It would always be best to follow your heart and be wise in choosing the best marine toilet to accompany your adventures. After all, it’s you who will benefit from the comfort it provides.
