Hi Pete,

Yes I would be interested in more info on the toilet. First hand info is
good on make/model, cost, installation etc and whether it turned out to be a
good idea.

There was insulation in the ceiling, some practically desintigrating from
moisture damage. The insulation looked original and had an unpleasant odor
once I got the ceiling off.

The hull is fiberglass and the decks are glass over wood. The entire cabin
is ~3/8 glass with wood bonded to it to hold panelling, outlets, lights
etc..

Hi,

My neigbour has fitted a composting toilet, I can find out some
details if you're interested.

Is there any insulation under the upper deck? If not you could use
panels of isocyanate foam ready laminated to thin plywood, they would
give some insulation and a vapour barrier. Would be worth sealing the
edges with foil tape to stop them crumbling or water getting in.

With cupboards have plenty of insulation or ventilation behind/under
them, or any clothes or even books in them could get damp and mouldy.

Wood is fine for flooring but in areas it may get wet like a shower
room it's well worth treating it with preserver.

What is the hull and upper deck made out of BTW?

cheers,
Pete.
