Can I ask which sealant you used for around the thetford? I had great problems in my build with it not sticking to the polyurethane, I rang Thetford, they couldn't/wouldn't advise, every sealant company I contacted said their product wouldn't stick long term either, Thetford do supply a rubber filler strip/seal, but I sold the van before trying that solution. I wish I'd done videos, I do have a rake of pictures though, I too passed on the bathroom basin, do you really need two sinks in a van, NO.
Tbh Kev I can't remember :) Got to do it again though very soon in new build (using same loo as not a fan of electric flush models) so will try and remember to add what I use in the bathroom video. It has instant hot water (first of it's kind in Europe) and a power shower :)
