Has anyone successfully installed a wet room in a narrow boat. If so how successful do they feel it has been. Thank you in anticipation of some sensible answers.

I am planning to convert tiny WC compartment on steel hulled Dutch Cruiser. Would be useful to receive any ‘do’s , ‘ don’t ‘s / suggestions / advice please. cheers in advance

Excuse the poor video but after ripping out the terrible wet room which was going onto the base plate we took some inspiration from small motorhome layouts and after getting the toilet second hand we are more than happy we have managed to get a proper shower and bench toilet with gulper in the 100cm*70cm space without losing any of the two sleeping areas and storage on our 26ft narrowboat. My question now is what to put on the walls. We have lots of tiles left over from our recent house renovation and some shower wall panels which are backed onto ply (though I think the issue will be getting them inside, even with the door off)! We could look at the cheaper plastic wall covering although I don't particularly like it. Any other suggestions and if tiling any particular adhesive or products to use? Ps, the wood inside was what was in before, it had those plastic thin panels covering it (siliconed over the wood). And I know many people aren't a fan of wet rooms but we have a tiny area! Hope the links work! https://photos.app.goo.gl/moHy3HPVpVQ8dGNQ7

Arranging drainage on a boat that heels is tricky with a wet room, you risk it running out of the door!

Have a look at how they do it in glamping pods, I hired one that had a combined wet room/toilet that was similar size to a standard toilet cubicle.

Our only experience of a wet room on a hire boat wasn't great. The shower and loo were in the same wet room so you had to cross a wet floor to use the loo which inevitably resulted in muddy footprints or wet feet. We assumed it had a leak in the lining somewhere as you could hear squishy noises as you walked around even it was dry. It went into the "not having one of those" file.🙂.

We currently have a 36' lumpy water boat - the twin tub lives under the bed in the aft cabin and the washing hangs in the wet-room/shower.(No tents on that one).

I did - the figures quoted of ~80 - 92% are under specific conditions - kitchen and a wet room (both very high humidity) and a rate of exchange which would never be found on a NB. A NB is pretty much a single room.

Moisture resistant is the green stuff. It’s still not great and certainly not for exteriors or shower enclosures. WBP / marine ply is fine. Far better to use one of the modern waterproof systems like Wedi. When we build clients bathrooms we treat walls and floors as if it’s a wet room even though 99% aren’t. Peace of mind, though expensive.

You need to look at bathroom and tiling sites rather than on here. There are plenty of methods and products to achieve a wet room. Start by looking at Wedi building board and Mapei tanking solution and then work your way up in cost from there. Schlüter’s ditra matting system is probably the best known at a price but it’s a job that’s worth doing well as you don’t want to be revisiting it.

One accident waiting to happen then might be, if you use your cauli-cupboard as an airing cupboard or drying room? Then it could become a wetting room by humidity or overflow. If the header is distant from the heat source, does one need some kind of steam blow-off valve? Air-r-jec valve? The idea of a boiling-mode failure having to blow the contents out of the whole system is scary.

Appreciate your response. Well yes I have a large flexible builders bucket that would be fine when we have hot summer weather! However a simple hot shower is essential for my purposes with no choice as to where to have it other than in the we compartment unfortunately. Perhaps you are not au fait with these small, 30 foot Dutch Cruisers but as one owner stated ‘ they are pocket boats ‘ , very snug and tight for space . Impossible to reposition a stand up shower , ready made or home made , anywhere. I meant to say that by me saying ‘wet room / shower room ‘ I am meaning either method will suffice , not fussed as such. It’s more to do with what’s best / what’s possible for the space. Yes there is only the gallery sink that is fine but I am convinced with ingenuity, patience and my 35 years of experience as a cabinet maker / antique furniture restorer- conservator, metal worker etc I will be able to achieve a basic watertight shower / wet room .

I’ve got a 1983 Mike Heywood that I’ve had for 30 years like that. Makes a small compact wet room bathroom. And modern epoxy paints solve a lot of issues. Mines also 50ft with a JP2 and a back cabin etc.

ok thanks for your feedback. I can understand the inconvenience perhaps on a bigger boat but in this case we are talking about a very small space indeed. The original sea toilet has been removed and replaced with the smallest thetford unit. There is no wash hand basin hence my idea to use all the space as a ‘wet ‘room Thanks for responding. I was thinking of whale gulper to pump out grey water with WBP marine ply shower tray tanked with fibreglass. Wall frame of stud work to support Showerwall

In August this year I bought a 30ft Aintree Bettle which had a build date of July 2018. The engine had only done 35hrs so all good. Then we have the problems: 1. The Beetle has a wet room with Thetford cassette electric flush toilet. To attach the wires and pipes to this toilet they cut a 4inch square hole in the wet room floor and then threw a few lumps of sealant over the hole. This was discovered when water leaked into the corridor. 2. The general quality and finish of the sealant application throughout the wet room was terrible - amateurish would be an insult to a bad amateur. 3. The windows internally have been sealed with a light brown sealant. This is also of a very poor standard of application - most windows have gaps in the sealant adjacent to the hinges. One window has no internal sealant at all ! 4. I then discovered water in the bottom of the kitchen cupboard. In an attempt to find out where the leak was coming from I had to pull out the fridge only to find water in the adjacent space and a spaghetti junction of hose pipes and jubilee clips covered in silicon. The leak was eventually traced to the sink tap which, surprisingly, was connected to a thin hose by a jubilee clip without silicon plastered all over it. The kitchen units, now leak free, are starting to bloat as they dry out. All of this I was prepared to grudgingly accept because I could work round it and the rest of the boat seemed fine and virtually new - or so I thought. Now we come to the biggy. 5. 2 weeks ago I decided to have the boat serviced. The day it went in I got a call from the yard to say I need to come and look at the boat. Why ? Because the engine had been incorrectly fitted ! The elbow joint at the bottom of the sump was resting on the steel crossbeam of the hull. It had gouged out a grove in the crossbeam due to the vibrations when the engine is running. Fortunately, this had not caused damage to the elbow joint which would have caused all the oil to pour out of the engine. Contacted Aintree Boats by phone regarding the engine whose first response was that at 15 months old it was out of warranty. Subsequently, I have had no response to emails etc. Technically they are right but morally no way. Legally I am not sure where I stand but I intend to find out and pursue for compensation if possible. Regardless, I think it is important to make people aware of my experience and the claims by Aintree Boats that their boats are quality built and their customer service excellent. A company should be judged not by its claims but by how it deals with genuine, valid, problems and complaints, especially when they are wholly responsible for the fault.

tony, thanks for response and suggestions. It’s early days and will not be doing anything until early next year weather permitting. So at this stage I am looking at as many possibilities of achieving a wet room / shower room. My first task will be to strip out the existing smelly , dirty and highly unhygienic boarding inside . This will also free up a little bit more hitherto boarded over space. Then I can see what is underneath floor, walls etc. The original sea toilet was mounted on top of plywood step so with that removed I estimate I will gain 4 inches or so.

@Captain GoodBoy Another wind up merchant, what the f@ck is it to do with wet rooms, could be bothered to read a 6 year old post. So @Captain GoodBoy start a new Thread with your idea, why are people replying/entertaining? Oh and welcome to the forum😂😂 Jen, are you taking this this seriously?????

Yep, that was what I expected. Figured it was worth asking. I’m pretty good with electronics and mechanical stuff but I know bugger all about plumbing or setting up a wet room.

On our 36' cruiser we had 3 toilets so we decided to make one into a wet-room (shower), basically it was the size of a double wardrobe. Got a 'man im' who measured up and then prefabricated the entire floor and sides in panels that'd fit thru the door, vam enad installed and gelcoated over the lot. Made a tidy job. Space is too small to get much in the way of a single picture, but a couple of pics showing the walls and floor. 1) Outside wall and window 2) Curve of the outside wall, an inside bulhead wall and the floor curved due to the shape of the hull. 3) Shower head and ceiling 4) Floor and plughole (water gravity fed into grey water holding tank)

Another question.... For our teeny tiny wet room we need a light, the other one has no label or anything. We are all 12V - would something like this be ok?

Thank you for putting me on your ignore list. I must be one of many. He was a wind up poster hence his final post. I asked what the f@ck has his post got to do with the original post/wet room of 6 year ago, it was not calling him. Your the one that started the calling bit with your “penis cranium” but you’ll deny it and say it was others that started it. 😂

Be at least 100 miles from London. More details please. Over a bath or new shower base? Or total wet room? Is the area already waterproof, tiled, lined? One thing I would always have on a boat with pumped water is a thermostatic mixer valve for safety reasons.

We very rarely use the toilets and showers on sites. It's just easier to use the ones on the van. Only time we have used site facilities has been when we have stayed somewhere for a few days at a time and we are conserving water and grey waste tank capacity rather than nipping to the service point. A couple of times in almost three years. We probably used the CRT facilities more when we had the boat, although again we rarely used them. It was easy enough to nip to the loo or grab a quick shower while the water tank was filling on the boat. If we were in the marina we would use the marina facilities to shower during the winter rather than the boat shower. There was no heating in the boat shower room as it was a wet room so it could drop a tad chilly in there at times. Much warmer in the toiler blocks.
