Adhesive for clay tiles

I need some technical advice for an adhesive to use for clay tiles
that will be installed on a cinderblock wall in Servus. There will
be many tiles of various sizes, but this adhesive would need to hold
under fluctuating temperatures, steam (as it is above a steam room)
and of course the pool environment.

I have two types so far:

    Pl Premium Polyurethane Construction adhesive
    Kerabond and Keralastic System

If anyone can recommend another kind of adhesive for use, I would
love any suggestions
