Boarding before tiling?

Are the fixings you're suggesting on the second skin I'm thinking of sitting on the bath?

cheers for all the replies btw.

Fixing where the board is on the existing upper half of the wall...

After Dotting and dabbing the bottom half of this wall I realised dotting and dabbing the second skin with the bath in may have been too much trouble. I ended up doing the whole wall with the second skin and now have a nice flat wall.

My next dilemna is tiling with the bath in. After reading all you helpful chaps on here I know the best way is to tile onto the bath as it creates a better seal. I'm concerned about damaging the bath and the pain in the *** of access when the bath is in though.

Is it possible to fit the bath, lay the bottom row of tiles along the bath and down the sides, let them set, remove the bath, tile and grout the remainder and then re-fit the bath?

Are there reasons why this is a bad idea? Any tips?

I'm also swithering wether to cut the bath into that second skin of PB as well.

cheers
