I am replacing the toilets on my cruiser. After checking out new toilets and the pipe layout on the boat i am strongly considering one piece toilets put in houses.

They are much more efficient and smaller than they used to be. Many of them have the power flush capability.

Adding a pump to refill is easy and a 1.3 gallon requrement from a 30 gallon water tank will give you a minimum of 20 flushes.

Any ideas or examples to ponder ?

Thanks

It's a radical departure, but have you considered a composting/desiccating head?

bulletproof
doesn't stink
easier/cheaper to install
"proper toilet appearance" (i.e. not a bucket)

Two well reputed brands:

Nature's Head Composting Toilets

Air Head Composting Toilet | For Boats, RVs & Cabins | Environmental Toilets with Compact Convenience:

I have an Incinolet. Turns waste into gray ash. Requires a plastic pipe vent. If you run a generator or have a decent inverter, you don't have to worry about no discharge zones, don't need a sewage tank and can use it at the dock. I have one that has been in daily use for 5 years w/o any failure. Mounds of paper or womens' products don't bother it. No replacing macerator pumps, joker valves or repairing waste plumbing.

IIRC, a manual marine head uses 0.6 gallons per flush. That's a 3:1 ratio, which means you'll be filling up your holding tank three times as fast.

Can your system or cruising grounds handle that? If you're always offshore, not an issue, but inshore?

Also consider the weight difference.

Good luck.

PS -- If this was such a good idea, wouldn't more folks be doing it? Might want to ask yourself why and why not.

Pretty cool, never heard of it, too bad it draws so much power.

Otherwise an ideal solution.

We have an electric toilet that dumps over board when it is appropriate and a composting toilet that is a much better option to a holding tank.

Another happy composting head owner hear (Nature's Head). One of the best upgrades we ever made to our boat. Simple, efficient, no holes in the boat (aside from an air vent), it can never clog, and no more worries about carrying sewage sludge around. Let us recover lots of space without all the plumbing and holding tank.

Best of all, guys have to sit -- which is a good thing since aim deteriorates with age and bouncy seas

Mike, I have the Natures Head also. I like it because the fan is on the unit and there isn't a separate seat.

I'd worry about what happens to a typical gravity-fed household toilet at a 20 degree angle of heel.

Just get a marine head or a composter.

No sense skimping on an important function like the toilet.

I'd prefer an electric macerating marine head using a freshwater supply. Two I see mentioned often are Raritan's Marine Elegance and the Jabsco Quiet Flush.

VacuFlush is another option with a similar benefit: low water consumption and resulting lower holding tank fill...

Southernpride,

Oh God, who in their right mind would even consider putting a composting outhouse inside a 53ft motorcruiser?

Here's a serious answer. I think seawater would eat up the internals of a traditional toilet if it's hooked up to seawater, so don't go there. If you intend to flush with freshwater, there could be a problem with backflow and discharge since a traditional toilet opperates on gravity discharge.

Install a push button macerating marine head.

I second the macerator head . They work great and use very little water if designed right . I built my own .

If I'm understanding you, your suggesting install a household domestic toilet into a boat? A toilet with a ceramic bowl, separate top and uses between 4 and 12 litres of water per flush?

Why?

To do it, if this is what you have in mind. You will need to replace any internal steel parts, screws, split pins with stainless. You will have a big problem if the bowl breaks in the pounding seas. And you have a bigger install problem with how to plumb what is generally a 100mm exit pipe.

Why? Would you do this
