Tiling into a corner

[OhGranny]

Hi Everyone
When tiling into a corner do you have to allow for expansion / contraction.
I mean do you butt the tiles up to each other or leave a gap - if they are butted up surely you can't put grout in and if they expand what then?
I was thinking to fix them so the front edges of the tiles are set so there is just a grout line apart at the inner corners.
Fixing them this way means that there will be a "square" of empty space the thickness of the tile + cement in the very corner of the wall.
Hope that makes sense but this is around a bath with a shower above and I am thinking once the hot water hits the tiles they could expand a little.
Any help greatly appreciated.

You're right in thinking not to butt tiles up in a corner but for the wrong reasons. Don't worry about expansion of tiles, be more worried about wall movement.
Ok, so here's what you do. Tile the back wall first and leave about 2mm gap at the corner. Then tile the wall that's 90° to it. Don't butt the tiles up. Try and leave a 2mm gap again.
Once the tiling is finished, don't grout the gap - silicone it. Like this:

Love the drawing - I tried to draw what I had in mind couldn't figure it out.
Well done !!!
Looks right - thinking of what I was going to do there would have been a void - now there is something for the silicone to adhere to - was dubious about grout - mate of mine is having horrendous problems with grout constantly cracking around the bath. Not as easy as it seems is it !!!!!

thanks a lot.

Tiles get Blown when butted in corners .. seen whole walls cracking coming away cause some numpty "tiler " has grouted in expansion joints ...
3mm is most needed an silcone can hide all corners nicely as gcol(lol)
has superbly drawn here

won't the silicone be a slightly different shade of colour to the grout?

Depends what colour you use.
