what can I use to reattach two shower tiles?

You can use tile adhesive or silicone,which when cured is as good as any glue. Clear away any loose or flaky material from the back of the tiles and off the wall. Try and loosely fit the tiles first to make sure they will fit back ok. Then apply the adhesive or silicone in small dabs to the rear of the tile or directly onto the wall then refit the tiles applying a small amount of pressure so that the tile grabs. You may want to consider using a small amount of fix and grout which can be used as a dual purpose adhesive and grout. All materials are readily available at B&Q etc Hope this helps

If it,s only 2 tiles just use 5 spots of the grout on the back of the tiles and give them time to go off before grouting the area around them,if they came off easily I would be concerned about the rest of them if it is a wet area i.e shower or splashback.
