Finishing up getting all the prep work done in a total rebuild of a
tile shower stall over slab in Florida block home. Picking out wall
and floor tile and being sort of new at this we have some questions.
We're going to use the MAPEI Aqua-Defense in the base and up part of
the walls to seal well and it's a base for the tile. Our main
question is which is better to use, mortar or tile adhesive for
mounting the wall tiles? We've done floor tiling but on the wall we
can see the tile possibly "settling" after some of it's up if we just
do mortar mounting. But the adhesive looks like it would leave gaps
or air space between the cement board and the tile. Suggestions?

And any recommendations on what the best mortar/adhesive is to use for
the wall and the floor? And what about the grout and the sealer?

Thanks in advance for your suggestions and advice.

I wouldn't ever use adhesive in a shower, it is best for dry locations.
