I know this has been covered before..(dohhh..) I have to do a full retile of a bathroom. I know that many will say fit the bath then tile but this is a smallish room and i feel the bath would get in the way. Also for full tiling jobs i think its probably better to mark the line of the bath,fit a batten just above that line,do the tiling so ensuring that it is nice and level,fit bath,tile down to infill to edge of bath. If you just fit the bath and make it level then use the edge of the bath as a level datum,i think this could be asking for trouble. Inevitably modern baths may "give" a fe mill;s and also,its difficult to get them perfectly level. Not like the old cast iron days where it stayed where it was put.
Any minor inaccuracies would be magnified over a full tiling job,corners of tiles would start to not meet square on/point to point and the finished job would not be so good. Even on a half tile job round the bath,this can become apparent.
Any thoughts?
