building new bathroom walls

[TopDonkey]

Right, i've finally decided to move the bathroom on my boat (loo, shower and sink) from the back master cabin to the front cabin area, I've knocked out the old bathroom already as i'll need all the fittings and sump pump etc for the new one i'm building.

The old bathroom was just built with 18mm blockboard and coated in some sort of rubbery stuff that wasnt particularly pleasant and a pig to keep clean.

What i want to know, is building methods really, I think the best way to go is to create a stud partition out of timber to the size and shape i want the bathroom to be, then line the outside with 6mm ply and paint or stain and varnish it, but the inside, i was thinking of using the pvc decorative cladding to make it a bit (lot!) nicer than it was before, has anyone used this stuff on a boat before ?, i was thinking of using 3mm foam cored 8x4 sheets of white cladding and glueing it to the stud partition directly ?, does this sound like a good method to use ?

I found this stuff on Ebay and wondered if anyone has any experience of using it ? and can offer any hints or tips when working with it or even the best place to get it at a sensible price

The forward heads on my yacht is between two bulkheads of marine ply and varnished. It looks neat and tidy and is very easy to clean. The aft heads is much the same, marine ply, except its lined with white a white coloured plastic veneer. I cant remember the name of it but it was a very common table top finish years ago - getting old, brain is fading.

Anyway, out the two I far prefer the varnished wood. The white veneer shows up dirt very easily, especially in the corners and edges. It is far more difficult to keep pristine. As my yacht is a middle aged lady the veneer has lifted where the sun strikes it through the porthole. Also in front of the heads its lifted. After you build your bulkheads around the new toilet I would line them with a thicker grade of marine ply because its a shower area and varnish.

The only problem with sheets of white cladding board is that they expand and contract significantly more than plywood. This risks it delaminating or buckling where attached to the ply.

If the walls are straight do you need a stud wall to hold the ply? Maybe a slightly thicker ply could slot into a channel fixed to the deck-head, sole & hull. If you used this then the foam PVC would have a large area to glue onto - assuming there is a suitable glue that won't "eat" the foam...

Just a thought.....

Formica ?

I lined the heads on my small motorsailer with 3 mm pvc, bought as 8 x 4 sheets. Made paper patterns for each wall as the pvc is fairly rigid, cut with a jigsaw. Used one of the modern no nails type of adhesive to secure it all. Quite a fiddly job to do but very successful.

You could try the below a marble effect tongue and groove paneling from B&Q, this what I will be using to refurb my heads. They also do it in plain white.

We relined some showers at the Scout activity centre with these products.
Very helpful and supplied the adhesive as well. Easy to cut panels and various profile plastic channels are available for the corners and wall/floor joints.

Do not use food-grade UPVC as the adhesives are limited to very expensive ones. Nothing much sticks to it.

You can buy excellent bathroom ply sheets that have a laminate face, basically a marine ply core with a waterproof laminate face. You could then glue formica or similar laminate to the other face and have a two sided wall which id how thw heads in our boat were built

Wow! thanks for all the replies everyone, its exactly the information i needed and more!, i'll go through everyones suggestions and pick out the one i prefer

I'm not a fan of varnished wood to be honest, although theres loads of it on my boat, i'm slowly painting it all subtle pastel colours to brighten up the interior.

I'm also a bit of a clean freak, so the bathroom will be kept spotless anyway, so no worries about that, i have plenty of spare time to keep everything up to scratch

Thanks
