waterproofing a new shower in bus

How about flow coat! the stuff they use over the top of the ply flooring on fibreglass boats.

Putting it on is a bit tricky as it's quite tacky and lumpy thats why they spatter another coat of a differant colour over the top to mask it.

Cheers.

I use painted steel for showers it is lighter than PVC and can flex with the body.
I go to a white goods manufacturer and get prepainted steel that is a lot easier to clean than colour bond. Eric

Hi - we went through the motorhome construction back in 2005. Started with a bus full of seats - and the end result is on the cover of the CMCA journal "The Wanderer" - current issue February 2011.

I used lamipanel to sheet the shower toilet walls and ceiling. Used genuine lamipanel internal corner, external corner and straight joiners.
No mould or leak issues. Another good trick is to give the whole interior surface a good polish with automotive product BEFORE ever using it. The water beads and runs off like off a ducks back and soap also doesn't stick as easy.

Some construction photos including the bathroom can be seenhere

thankyou for your posts will take all on board
