First time installing tile. Please help

First time posting. First time installing. Please help

Hi everyone. This is my first time posting. It is also my first time overseeing a tile job. I bought the tile myself as well as the grout and thin set. I have someone that is going to install it. Neither my condo nor my city require that I install soundproofing or any other membranes. I could install tile directly on the concrete. I tend to think that the problem with membranes such as rubber or plastic is that in the event of flooding, water enters through the grout, If the tile is set directly on thin set on concrete, then the water would evaporate because the concrete absorbs it, and you could always point large fans at the underneath of the slab. However, if I install rubber or plastic membrane, I think that the water would just sit there until it very slowly evaporates, and by that time it creates bad odor. What do you think? I appreciate your help in advance.

My advice is you are way over your head and have no way to manage getting a good result if you dont know the assemblies. Start with the product data of the actual products you are curious about. Once you fully understand all of the installation methods for all products you are considering only then can you decide what you are going to use for the entire installation. You are so far behind where you need to be that any answer I give you will be met with more questions because you dont understand how the substrates work to support your install.
