I do not want to make this stone out to me a bad stone, but you need to know that it is not the best stone for your steam shower. This stone will etch easy, scratch easy, and oxidation.

Ok that is all the bad stuff, now here is how you deal with the stone Have it hone to a 600 grit or 400, this will stop you from seen any etch marks that would be visible in a polish stone. Seal the stone correctly before you ever use the shower, this will pro-long the the look of the stone and stop the oxidation. Now here is the best part, enjoy your stone. use proven stone soaps for day to day cleaning.

If you would like for me to point you in the direction of a few proven stone soaps that would work well with your type of stone and under the conditions in which you have the stone, all you need to do is ask.
