    Marble is a soft stone... you might want to use a "marble look" porcelain or ceramic tile for less/easier maintenance and longer wear

    While not all marbles are delicate, most are highly absorbent, and thus easy to stain and etch. Polished marble shouldn't need sealing before you apply grout, but tumbled marble does -- it's so absorbent that the grout itself will stain it during the installation process unless you seal it first. Sealing the tile before grouting doesn't get you out of sealing it after grouting, though; to protect your tile properly, seal it a second time after the grout cures. Use an impregnating sealer for best results.

    You'll be ahead in the long run if you seal it well. Check with your local store where you bought the tile for their advice.

    I would not do it.
