Tiling onto plywood

Ring up Bal or Mapei technical help department and see what they recommend.

The tiled plywood ceiling would be a good incentive not to stand in the shower too long. :lol:

The bal microban grouts are formulated specifically to stop mould. There's the mapei equivalent but they are more of a pain to use I find. Bal, ardex and mapei are usually the choice of the pros though.

Oh and for the ceiling I would definitely just opt for paint lol. Tiles generally don't stick too well to plywood as it is without having them above your head

I spoke to a builder friend yesterday and asked him about epoxy grout. He suggested it would be beyond my DIY skills to manage a neat job. :lol:

So I reckon I'll be using bal microban grout.

Meanwhile, just to show I don't always listen to reason, I decided to tile the shower ceiling anyway. :yikes:

I figured that if they started to fall off, they would just match the shambles that is the rest of the house. It's surprising how relaxed you can eventually get about windows where the original wood lintels have crumbled to dust, cracks in the walls and doors with such wide gaps that toads find their way into the kitchen overnight.

You don't want to use epoxy anyway 😉

Oh and the tiled ceiling warning was more incase they fell on your head

What did you use to stick them?

Plywood expands and contracts more than concrete backer board. If water finds its way onto and into your plywood, the plywood will expand. The expansion will create a soft spot under the tile that will give in when someone steps on it. This will almost always cause cracks in your grout and in some cases will pop tiles up completely.
