Wouldn't expect you to recommend anything else Glynn 😳🤣🤣Tilemaster Magix-S White is the one I would recommend. It is an S1 rated adhesive and totally suitable for ceramic mosaics in a bathroom environment. Check out the Tilemaster adhesives web site for your nearest supplier and a TDS or contact the technical department.
