I'm about to start tiling my renovated bathroom and was wondering what the
pro's and con's are of tiling behind installations (e.g. toilet cistern &
sink) vs. tiling around them. As far as I can see:

* Tiling behind:
+ easier to tile,

+ better sealing of the plaster away from splashing/condensation
+ more scope to move fittings/install new fittings without re-tiling
- more likelihood of broken tiles when drilling to mount the fittings

* Tiling around:
+ easier to mount fittings
- harder to tile
- harder to seal

Anyone got anything to add / any recommendations on how I should do it? At
present I think I'll go for the tile behind option.

Cheers,
James
