Tiling a shower room ceiling

[Frazer Gould]

I am a reasonably competent DIY tiler having fitted out kitchens, showers, toilets etc for my three daughters (and myself when they give me time!) but in all my projects gravity has been my friend. For a change I am gutting a shower / toilet in my own 200 year old house where the walls are up to 100mm off vertical, where there is no DPC and the room is built into the side of a hill!!!
I have solved all those issues but am now faced with my wife wanting the shower ceiling tiled. This is one task I have never done and gravity will now be my enemy!
Any advice on the adhesives to use, the best tile format, and any other tricks of the trade will be most welcome. The area to be tiled is 1200mm x 900mm and it will ultimately have 2 LED lights and an extractor vent cut into it.

Go for Wedi board.
Go for mosaics for ceiling - and if you get permission from your wife make them mosaic mirror tiles!

Frazer, here's one I did last year using the methods and materials mentioned above. There will be so much humidity up there using an XPS board is a must. Also use a good quality anti mould grout. If there's a good local independent tile shop near by go and see them, alternatively topps tiles although expensive, they sell all that you need
