It may not be all that expensive either, I first did the fresh head conversion, but my wife some how could still almost clog the thing.
Rather than fight with her about that I then converted to a macerating toilet that is fresh water flush.
I swear that thing could eat news print.
Yes it of course increases fresh water consumption, but after charging all my head hoses and a new black water tank, there is no more smell with my heads than there is in a house.

Re: The odoriferous marine toilet...

The stink is usually anaerobic bacteria growing in head, hoses, holding tank. Google anaerobic and aerobic bacteria to get a basic understanding of the microbiology involved.

Your head won't stink if you do most or all of these things, viz.:

flush with fresh water or gray water. not sea water. Pour it into the bowl through the hole you sit on and use plenty of it to clear the hoses. Dish water, rain water, bath water, transom shower rinse water are all better flush water than sea water.

Some people flush their TP and some put it into a plastic bag and take it ashore with the trash. What ever you do, don't leave soiled TP in the head compartment. Get it into the going-ashore trash right away.

Rig a 12V bait tank aerator to pump fresh air into the top of your holding tank. This encourages growth of aerobic bacteria that don't stink, and the aerobes prevent the growth of anaerobes that do stink.

Rig a piece of PVC pipe full of activated charcoal as a scrubber for your holding tank air vent. Cobble it up with parts from a home store. Fresh air should be pumped in and then the tank air scrubbed and discharged constantly. There will be no stink if you do this. Change the activated charcoal a couple of times a year.

You can add chemicals to your tank if you wish, but the above measures are the essence of an odorless head.

Re: The odoriferous marine toilet...

I believe I learned this from Peggy, but we put bromine tablets into the strainer and that does the trick for a couple months. You can tell when the tablets need replaced because it'll start smelling again. The bromine does not attack rubber like chlorine does. YMMV, but that was an easy fix for us and has made my wife happy for the last 7 years of living aboard

Don't let her eat nuts! Macerators and nuts don't mix, I know, my girlfriend likes nuts.

Re: The odoriferous marine toilet...

Composting head all the way eliminates all the issues that can come up with a more traditional head.
No need to have 2 holes in the hull that may start leaking , no hoses to get permiated with stinky poo and need replacement, no holding tank to need pumped and take up valuable stowage space. No wye valve to switch when entering or leaving ports, no flushing toilet and all the associated stinky maintenance , no more joker valves to replace, and best of all no more clearing a clog at 3 am in a heavy seaway.

Fine if you like emptying your litter box.

"Composting" is not entirely accurate and intentionally misleading. It takes time for poop to compost so unless you have two on your boat, there will always be some fresh poop in the "compost".

I've noticed that new boats typically have traditional toilets on them. I suspect there's a reason.

The issues you mention above with traditional heads aren't really a problem for most of us.

the term composting is not misleading . The toilet is just one part of a system .
Just like your toilet is just part of the sewage treatment system.
Big difference is when your tank is full you have to deal with it immediately.
With a composter ( if you prefer desiccating) toilet you have much more flexibility as to when you deal with your deposits.

I do have two compost holding containers on my boat . It also allows me to just empty compost about every 5 or 6 months ( just me on the boat.)

Those who have 'em have become a cult, true believers who are as committed to making as many converts as the most dedicated Jehovah's Witnesses are! To them I say, whatever floats YOUR boat for YOU is fine with me.

But I'm not a fan. Except for a couple of versions that are actually just litter boxes, they're a very expensive way to avoid the minimal maintenance that easily prevents 99.9% of problems with traditional systems if the system is installed correctly.

To each his own.

It's not a cult, sorry. It's just a whole lot easier and cheaper.

Re: The odoriferous marine toilet...

i have found the folks who have reeky heads donot know how to use em. must flush many gallons of water thru every couple of days. not enough water thru , peeyooo.
also--for closed systems, odorlos enzyme additive. is only thing not skanky in holding tank. out in open ocean use vinegar--just donot mix with odorlos as it will kill enzyme. enzyme is awesome for no skank whatsoever.
do learn how to use a proper marine head.

Re: The odoriferous marine toilet...

I've always thought composting toilets would be greatly improved if you used clumping kitty litter in them. Then you can poop and pee in the same container.

You know I hadnít thought about that before, but if they are so good, why not use a composting head for a cat litter box?

Re: The odoriferous marine toilet...

I have found that 99% of the people who dislike composting heads have never owned one and 99% of the people who own composting heads have owned the traditional marine head and prefer composters, speaks volumes I believe. We are not a cult just trying to educate that their is another viable option.
