Really I'd advise them against the use of marble full stop !! Steam rooms are not to be messed with as the water is of the finest kind !! It will penetrate any weakness !! Marble is a natural product and it won't stand up well to a steam room !! Use a wedi board or equivalent and tape joints with the waterproof jointing system !I d use mapei wps waterproofing system and do 2 coats
