New pool house build & flooring selection: salt water compatibility

This is a somewhat obscure question. We built a poolhouse on a concrete slab with a vapor barrier underneath. Ohio weather with temperature fluctuations, and its an unconditioned space.
We are exploring a waterproof vinyl click-lock tile (the solid core with less expansion/contraction due to temp), and also a real porcelain tile option. I did some research and around saltwater pools & coping, a chemically-resistant epoxy grout is recommended. Feet will be wet in the poolhouse, should I be concerned about grout selection so much? Does anyone have "traditional" grout near / adjacent to their saltwater pool, and do you have any staining or "eating away the grout" issues from foot traffic and saltwater left behind?
Secondly, if we pick a dark floor (either option), will saltwater "rings" show up from foot traffic? For instance, when I pumped my pool down the other day, the black pump housing had a slight white residue look where residual water drops dried. I assume the same will happen with foot traffic on a dark floor.

Any feedback or advice on this topic? Both on the best flooring material option for the application, saltwater compatibility, and so-on. Thanks in advance.
 
Salt water from pools does not eat away at grout. Salt water will not damage your flooring.

Salt water may leave salt on the flooring when the water evaporates. That should be able to be mopped up with normal floor cleaners.
