Best Marine Toilet Buyer’s Guide

The different types of boat toilet

There are a number of types of marine toilet that you can opt for depending on your needs, budget and preference.

Let’s take a closer look at what they are.

Best electric marine toilet

 

First up is the popular electrical marine toilet. There is a wide range of products available in this category, the prevailing difference being the type of pump used.

The entry level electric boat toilet (and therefore the cheapest) generally uses pumps that feature a combined chopper and impeller. The problem with these is that they are very noisy to operate, (an issue that can cause embarrassment for guests).

Because of the inbuilt electric pump system these toilets can be installed above or below the waterline.

Other advantages include the convenience of the electric operation, (you do not need to manually pump to flush the toilet) and the fact they are so simple to use.

Furthermore, if the toilet includes a macerator there is less chance of refuse clogging the lines.

From a negative perspective, electric marine toilets cost more and are more difficult to install.

Manual boat toilets

Most manual head marine toilets utilise a hand or foot pump system to dispose of the waste.

The great thing about manual toilets is the fact they are cheap, relatively easy to install, (no need for power lines) and reliable.

They generally give off more odours however, as the manual pump flushing system clears less efficiently than the electric models.

Portable boat toilets

It could be that you’re on the lookout for the best marine portable toilet.

There are a few benefits to the ‘porta potty’. The number one reason to opt for a portable toilet for your boat is affordability and convenience.

They do not need to be permanently installed as the waste is simply collected in an inbuilt tank beneath the unit. You can empty this waste at any sewage collection point once you have moored.

You do have to consider the fact that fresh water (10 or 20 litres) has to be added for flushing, (and obviously needs to be refilled as often as required). You also have to carry the necessary chemicals onboard.

Composting toilets

Finally there is the composting toilet. This is becoming a very popular choice for boat owners (and beyond as they suit any type of mobile convenience application).

So what goes in to making the best composting toilet for boats? Odourless operation and ecological friendliness are the two biggest considerations.

Boat owners love the fact composting toilets very rarely smell. There is no need for hazardous chemicals and they do not cause pollution.

This type of toilet uses two receptacles, (one for number one, the other for number twos).

The composting toilet works by allowing oxygen to dry and compost the waste. Peat moss or sawdust is added to the waste to speed up the decomposition as well as cover any smells.

The whole system is very reliable and needs little maintenance. They are also the best waterless toilet as there is no need for water and the waste can be safely disposed off.

An issue that may put people off the composting marine toilet is the fact they are taller than other types. In fact, if space is limited you may not be able to fit one into your boat.

They are also more expensive to buy.


What to look for when buying a marine toilet

If you remain uncertain about the type of boat toilet you wish to buy, you may want to consider the following issues in order to narrow down your choice.

These are just a few areas you should consider before you buy.

Eco-Friendliness

It goes with out saying that you should never dump your waste overboard. However, the level of eco-friendliness each toilet has does vary.

The best electric marine toilets will include a macerator pump. This will grind up the solid waste before it is disposed into the holding tank.

Not only does this increase the amount of refuse you can store, it also helps speed up decomposing once the waste is fully disposed off.

As we mentioned above – nothing beats the compost toilet for eco-friendliness. Yes they cost more, however if you really care about the environment and wish to lessen your impact on it, there is no better choice. They also smell a lot better too.

Materials

When buying a marine toilet you should definitely consider the materials the unit is made from.

A porcelain bowl is stronger, easier to clean and more familiar than a plastic model. However, they are more expensive.

Most portable toilets opt for a plastic construction because weight is clearly important, as is price point.

If your boat utilizes a salt water system the macerator mechanism should be constructed from stainless steel or bronze.

Likewise, you will need anti-corrosive materials used on trimmings and fasteners – especially if your toilet area doubles up as a shower.

Footprint & Hook Up (access points)

You should also consider the footprint of the toilet and the space you have available. That goes for height too in the case of a potential composting toilet installation.

The toilet needs to fit your head space. Serviceable areas also need to be reached once the toilet is in place.

There is also the issue of installation and hook up. How will you link the toilet up to the power if you have chosen an electrical model? Is the wiring up to the current draw of the motor?

You need to think about the raw-water intake and overboard discharge. These need to be located on opposite sides of the keel if possible.

Fresh Smell

Again, the composting toilet wins on this. Not only will your decomposing waste be odor free, you will also be able to use it as fertilizer for the garden.

Vacuum-flush systems (available on some electric and manual models) are also good at tackling nasty odors.

They utilize on-board fresh water to flush, (which is one issue to consider). However, the system is cleaner and helps eradicate odor by washing away bad smelling bacteria.

Noise Levels

Finally there is issue of noise. Cheap electric toilets and manual units are generally the loudest when operated. Those pumps and macerators will make a din.

However, more expensive models do attempt to quieten the mechanisms by design. And if you prefer to perform your morning ablutions without waking everyone else onboard, a quiet toilet may well be worth the asking price.


Best marine Toilet Reviews

Having a top-of-the-line marine toilet is a must-have for boat owners. Now it’s time for us to give you the low-down on a few of the best in the business.

1. TOP PICK ELECTRIC: Jabsco 37010 Series Electric Marine Toilet

The Jabsco 37010 has a push-button operation, and a high-capacity macerator and bowl scavenger pump. In plain language this means dry bowl valves and hand pumps are now things of the past.

By just pushing a button, the self-priming flush pump rinses the bowl, while the macerator and scavenger pump grind the waste and pump it out of the toilet, making this an extremely “polite” toilet for your boat.

The priming feature on this Jabsco depends on the flexible impeller flush pump, which also handles a greater quantity of solids in suspension than any other type of rotary pumps.

The bowl has dimensions like the commode in your home, 29″ long, 14.4″ wide, and 14.8″ high.

Everyone who is familiar with former marine toilets will thank you effusively for installing a Jabsco 37010. The Jabsco is a generously-sized toilet by marine standards, much to any hardy captains’ delight.

For fitting the toilet you ill need to check the following specs alongside the space you have available.

The compact version of the toilet is 13 1/4″ x 17 3/4″ wide x 16″ long. The inlet hose is 3/4″ in diameter; the outlet hose is 1″ in diameter. The bowl comes with a 1″ to 1 1/2″ adaptor for the discharge hose.

The Jabsco parent company, Xylem, is all about sustainability and is focused on solving their customers’ most pressing water problems and setting industry standards for fluid technology applications and water resources. For many skippers, this is an important thing to know.

Pros of the Jabsco 37010 Series Electric Marine Toilet
  • The product also comes with 12v switch box that is suitable for installation above or below the waterline.
  • This bowl is compact white vitreous china, and the seat and lid are household-style.
  • The Jabsco has a stainless-steel shaft and a permanent magnet-type motor that is completely enclosed.
  • It also includes a built-in backflow preventer to protect public water supplies from pollution.
The Cons

There’s a lot to like about the Jabsco, but, naturally, there have been problems experienced by some owners.

  • Some owners have had a problem with the toilet not pumping out, which, in turn, makes the toilet unable to prime.
  • In some Jabsco marine toilets, the motors have seized for some reason, or would trip the boat’s breaker when flushed. Some of these motors had to undergo a rebuild by their owners.

Bottom Line

Truthfully, all the problems found with this boat toilet were concerned more with older versions of the Jabsco, and, even then, the problems were fixable.

The Jabsco 37010 appears to be an excellent marine toilet, and the company seems intent on wanting to save the world’s water supply while making outstanding products at the same time.


2. TOP PICK PORTABLE: Camco 41541 Portable Toilet

Camco’s 41541 portable toilet is perfect for camping, boating, and almost every outdoor recreational activity.

If you haven’t considered purchasing a toilet for using almost anywhere, you may want to consider doing so when you see the many conveniences you attain from owning the Camco.

The top half flush tank holds 2.5 gallons of water and has a standard toilet seat and lid. A cap is included and is located on the top of the device to contain fresh water to fill the flush tank.

  • Although one owner acknowledged that the toilet was easy to use, she added that it was not easy to clean. Her recommendation was that you clean it each time you empty it. She added that the design of the tank did not allow solid waste to flush out properly.
  • Another customer said he had trouble returning his product to the Camco Company.

Bottom Line

Camco is manufacturing an affordable, handy, multi-purpose portable toilet. It’s difficult to ask for much more than that considering the price you pay.

  • Premium quality build and design with raised seat for more comfortable use.
The Cons

Again, this is a portable potty that is very well-liked in the market, but there were reports of a few minor flaws.

  • One owner bemoaned the fact that the instructions that came with the unit were not entirely clear.
  • A customer wrote that the levers, indicators, and buttons on the toilet lacked labels, making them a bit confusing to identify, at first.
  • Currently more expensive to buy than the Camco portable toilet.

Bottom Line

The Thetford is to porta-potties as the Taj Mahal is to a shed. The design is lovely, and the amenities do impress. The best feature could be the added height of the unit which makes it easier to use. It is expensive when compared to the lower priced Camco however.
