A client has a 4 X 7 steam shower. They will probably use the shower 2 times a week during colder months for duration of about 15 minutes. Can honed limestone or something comparable be used for the floor walls and ceiling of this shower? They also want a slab shower seat on one wall of the shower (4' X 18"). Do they need to be concerned about shampoos and conditioners staining the stone? I understand that it would most certainly need to be sealed on a regular basis, but is this enough?

Please make sure you know about steam showers before installation. That being the required waterproof membrane and the use of thin set versus mastic in this particular application and that the construction has the proper slant to it to allow for drip page on the ceiling...this is crucial! Honed limestone or something comparable can be used, but I would suggest a smaller size such as a 4x4 (or smaller) to allow for the pitch to the drain on the floor...the ceiling I would suggest up to a 6x6 just for ease of installation...12x12's on a ceiling with thin set is a time consuming endeavor...anyways a 6x6 on the diagonal looks best...the slab seat is also okay BUT...with ALL stone products, there is going to be potential staining or etching, even when sealed, in these types of application...I always tell my customers that they have to accept that over time that natural materials will change (like leather products) and that this is part of their beauty...if they cannot accept this then natural stone is NOT for them and they should choose a ceramic.
