Marine Heads, Composting Toilets & Accessories

RV or Boat, a composting toilet is our toilet of choice.

We love our Nature’s Head Composting Toilet so much, we made an entire series of videos about it:

If you want any extras the discount is good for the entire website, so, it’s a good idea to buy a spare fan and a spare liquid tank too.
The Backup Toilet: We still have one quiet flush macerating toilet and it is 1000 times better than the manual pump head that’s found on most boats.

If you’re wondering why we didn’t install 3 composting heads, here is the answer: We wanted to keep one head that can be flushed into the sea while we are out sailing in the open ocean (where it is legal to do so).  The idea being we will go through less coco coir and not need to worry about dumping toilets on long crossings. If we only had one head on board, it would be a composting toilet.

    Dear Curious Minion – Do you know whether Nikki and Jason purchased the mushroom vent cap or the shell cap as part of their Nature’s Head system for their catamaran, or whether that wasn’t necessary – IOW how did they vent their NH? Thanks so much for your time!

      Hi Kelly,

      I’m afraid I don’t know what they used to cover the vent. It’s possible that they just bought some type of vent cover from the marina chandlery, as they usually keep several types of vent covers in stock. Maybe Nikki will see this and chime in.

    Years ago while working on a Alaska crabber they had a toilet that would insinuate the contents of the toilet. No the boats never burnt down

    How do you manage residue in the toilet bowl without the typical bowl wash found in a water base system?

    • Curious Minion

      Hey Ron. There are several vids/posts on the blogs about the composting toilets. If you click on the composting toilet tab here I’m pretty sure the answer you’re looking for is in the “tips & tricks” post.

    Hey Jason and Nikki, now that you guys have been out cruising for a while with the composting head, can you comment on the availability of coconut coir in the places that you have visited? I know you had problems getting litter for the kitties, how about for the humans?

    • Curious Minion

      That got asked not too long ago and Nikki said that they haven’t had any issues so far. Whew!

    We have a normal marine head with zero odor. Lots of care was taken with the type of pipe we used as well as proper ventilation of the holding tank, making sure it gets enough oxygen. I’m sooooo glad it doesn’t stink!

    Nature’s Head is the nearest poop chute on the planet. We got one to eliminate flushing directly into the ocean on our forward head and promptly got another for the aft head and threw all plumbing and tanks overboard. Boat doesn’t stink and they work like a million bucks. We use peat moss. Bacon Sails in Annapolis has them for cheap.

    Vacu-flush fresh water heads offer a great solution to the s—-y smells & problems associated with marine heads plus they only use about 1 pint of fresh water!
    As you correctly pointed out salt water is a BIG problem in terms of the smell and maintenance associated with marine heads.
    The biggest downside is the extra space required for the system but they work well and are relatively low maintenance.
    I do not sell marine heads so this is not self-serving but comes from 30 years of boating experience.
