drylining plastering

Evening, Need to dryline a *very* small bathroom in a Victorian house. Space is at a premium. Solid double thickness exterior wall. Ground floor bathroom. I don't have space for insulated plasterboard. Any ideas on what I need to do? Have already ruled out D&D.....unless someone wants to...

I'm about to start dry lining my spare room....this will be my first time. I was just wondering with it being my first effort and I'll obviously be slow cutting and hanging to boards....how long gone will the adhesive last in my bucket before it goes off?
