The very best way to prevent problems with a marble installation in a wet area is to install a porcelain look-alike, Dani. See again post #42.

If you insist on real marble, at least find a competent contractor who can build you a traditional mortar bed shower receptor and mortar walls with a moisture barrier behind the walls. Or even CBU walls if you can't locate a real mud man. And install the tiles with a cementitious thinset mortar and use a cementitious grout. And see my warranty information below.

If you want to use a penetrating sealer, adjust your expectations to fit what the sealer might actually do or not do for your stone installation.

My opinion; worth price charged.
