Toilet arrangements

For occasional use when you should not discharge overboard and may satisfy local regulations, I recommend Abena Abri-Bag 10 Pack they fit neatly inside the regular Jabsco heads pan, I use them when visiting the Netherlands inland waterways as I have no space for a holding tank.
I get blocked, which I suppose could be convenient in context, as would a colostomy, but I dunno why they'd be especially coy about their bag thing just because I'm in Taiwan.

Intellectual property piracy poop?

I was thinking I might get a little bucket with a lid that could fit inside the toilet bowl, then I would often be able to bury ashore where discharge isn't reasonable. I have a trowel.

Might not convince The Bottom Police though.

Seriously, get RID of the portable toilet and build your own desiccating toilet. I've had both, and I would NEVER have a portable head again. Far less smell, even with the best chemical, and easier to service.

Read up on the operation of a desiccating head. It's not just a bucket. You need a urine separator and you need a good absorbent cover between uses.

My cruising cat has a traditional sea head and holding tank. It works very well and I prefer it for cruising. But for small boats and daysailors a desiccating head is simpler, lighter, and trouble free. Horses for courses.

Wot, no link to the DIY dessicator mentioned? I read all the way through expecting one, so I dont think I missed it.

OTOH it seems to be essentially...er...a bucket, so maybe build instructions would be redundant.

I think buckets are very useful, but I would be reluctant to pay 700USD for the commercial dessicator mentioned.

I can manage to piss in a bottle, and when I had the use of a garden I did so routinely. Perhaps its a bit more difficult on a boat though.
 
Bucket and yuck-it. Good.
If you are going to take a dump in a bucket best get some Sainsburys paper carrier bags, bio degradable, then you can sling the lot over the side. if you are in a marina best dump the bag the far end of the marina furthest away from your own boat. I personally never pump my toilet until I am 20 miles off land.🤫

I was thinking maybe Macdonalds carry-out bags, which are brown paper and ought to have a dessicant effect.

Garbage in = garbage out
 
it is not disgusting walking around with a Sainsburys carrier full of the whole families sh.., Dogs owners use see through bags which swing back and forth as they walk and as I have witnessed sling it over the nearest railway bridge.

The trick is keeping solids and liquids separate, so it’s a bucket and a jug or whatever, and a pan covering the front half or so of the bucket aperture, sloped with a drain hole to “divert” (that’s the term they tend to use, urine-diverting) pee to the jug. Thus you don’t end up with a wet mixture of both products, rather, a bottle of pee and a bucket of… well it’s not nice, but it’s the least worst format I’ve encountered.

I haven’t tried holding my pee while allowing the back end to discharge, but I imagine it might be a challenge. Also, there’s a lady to consider for the boat in question, a demographic more anatomically challenged by a bottle.
 
Yes I guess so bit like doggy poo bags but bigger 🙁
More like a children’s nappy (diaper). If it really is for “emergency” use they are a far simpler solution than any DIY to make a porta potty fit, install a sea toilet or build your own desiccating head. They are also sufficiently “basic” that nobody will feel the urge to use it when there’s a public toilet 50 yds away!

DON'T sling them over the side. Some asshole did this when we were sailing in Jura and I very nearly reported them (no signal and no VHF at the time).
biodegradable comes in many forms and most carrier bags will be the kind that need heat in a commercial facility to actually degrade properly. Either way, throwing bags of excrement over the side to wash up on a beach is not OK, just put them in a bin.
 
On measuring it looks like a porta potti won’t fit in the designated space so plan b is to fasten down a toilet seat over the plywood bunk top previously having cut a hole and put a bucket under.In the marina we have toilet facilities so my idea is just an improvement on a bucket and chuckit
Is the space too small in width, depth or height? Is the floor not level?
Different brands of cassette toilets come in different sizes and sometimes a choice of cassette size. If it’s the floor space not level, could you sort it with a built in plinth?

Going to take another look this weekend weigh up forum advice
 
Might not be wide enough. One would not want to foul ones hands would one.
Havnt tried with a Macdonalds bag, but in SE Asia hand fouling is traditionally part of the SOP so one is fairly accoustomed.

Its not part of the SOP in Taiwan, where toilet paper is de rgeur but until very recently you werent supposed to flush it, resulting in rather unpleasant bucketfulls. Flushing paper came in maybe 2-3 years ago (for example at the university I taught at), but may not be universal.

Elsewhere hands were considered washable and toilet paper nasty in many countries, though I daresay Western Decadence is spreading.

Different strokes. But maybe not "when in (classical) Rome", since I understand they used communal sponges.

The article was cut for length, as often happens. I added images to my blog, below. No, it is not complicated, but the devil is in the details. You buy a separator kit; this is vital. The urine and solids MUST be separated. The other parts must fit well. It must be operated properly, rinsing the urine separator with a light acid spray and covering each deposit with a thin layer of absorbent. Operated in this way, it is so odor free I operated one in the house for several months without a complaint from my wife. I would not have gotten away with that with a portable head!
Saildelmarva - desiccating head

Yes, $700 is ridiculous. But the whole is far more than the sum of the parts and it works a lot better than you perceive. And piss in a bottle (I also have a bottle on board, well-labeled with a scull and crossed bones) will not work for your female guests.

I had a conventional head on my cruising cat and thought the whole idea was completely ludicrous and gross ... until I tested, learned, and built one for my F-24 trimaran. It is simply not at all what you and many are guessing it is. It does not work like either a bucket or a WAG bag. This is something different and far more effective. If you have a sea head, I suggest you ignore the thread because it does not apply to you. If you have a portable toilet, this is much better.

Sometimes details are needed. As relates to a separating head:

You pee first. You can do both, but no need and perhaps less control.

Women also pee first, while perched nearer the front. Then they scoot back a few inches to finish.

Google "Kampa Khazi". 35 quid. Compact, and might save you some wood work.

Well, I would expect my sea head will need some work, as will my sea legs and my sea chest. I would also expect there would be regulatory and decency restrictions on its use, though I'm not currently sure what they are in the UK.

When I was living in my Romahome I used a little bucket (I think originally for PVA adhesive, similar available for paint...) for occaisional emergencies and buried the solid product in parks.

It fitted inside the spare wheel (boss side down) which sat on the edge of the step down into the rear overhang where the sinkette and stovette were. Quite stable and comfortable.

I used a newspaper lining and put the well sealed lid on after use, to limit smells and fly access, but so sealed it grew mould quite quickly in summer, so it might be better to just use the lid for transport and apply a loose dessicant covering instead, maybe soil or leaf litter.

I would think dried pine forest litter might be particularly suitable, and should be foragable, though drying may not be convenient

Pee and toothbrush spittings went in a wide-mouthed bottle and got dumped in parks and gardens on my way to the tube station of a morning. On a short (daily) cycle, treatment other than rinsing didn't seem to be necessary.

I've done similar here in Taiwan when the post-typhoon water supply outages have prevented flushing.

TBH I dont think any of the women I know, or have known, would cope with anything even slightly unconventional or inconvenient in this area, and I doubt they would cope with a small boat either, or at least not when that small boat might be driven, at sea, by me.
