I need to tile a shower that has a casement window in it. There is cement board installed flush with the window sill and jambs. The tile is glass, in approximately 7/8″ square pieces, and it needs to flow over the jambs and sill.
Do I:
1) score the hardwood sill and jambs and just use the tile mastic to stick the tiles on?
2)apply ice-and-water-shield and then diamond-screening (as used on floor tile installations) and then mastic?
3) screw on aluminum flashing and then glue the tiles to that?
Those are the suggestions I’ve had from tile installers. (The problem with #2 is that I have very little space to work with on the sill; if I build it up too much the window crank won’t work.)
I’m not using thinset, I’m using an epoxy mastic.
Would very much appreciate suggestions from someone who has experience with a problem like this. How do I ensure the tiles will stick when the wooden window casing inevitably expands or contracts?

The day before you start tiling, coat all of the concerned areas with the mastic/ epoxy. Give them time to cure and then start your tiling as usual. I'm not a big fan of windows in bath areas but when I have areas that require this type of attention, This is what I do. (I.E. Wall pockets for shampoo storage.) Good luck, Joe
I just did this. The pic's came out lousy so I won't bother. I fiba taped and thin set scratch coated the janbs to the cbu.........no stool. The windows were pretty high up and only adults use the shower. He promised he would dry of the lower jamb extension when it gets wet.
It shouldn't be done at all but sometime you have to give'em what they want.
