Honed will be less obvious. If it's etching, sealer or honing won't prevent it. I'd question whether it's just water, and what is in whatever you're mopping it with, too. (I only clean the marble with marble cleaner.) My only spots are around the toilet... Nothing to prevent that short of sitting. This post was edited by KevinMP on Wed, Apr 24, 13 at 23:04

Now I'm more confused than ever. Do you mean that if it was sealed before it shouldn't be done again until the old sealer is removed? What happens if you reseal something that has been sealed with a different product? Do you spray acetone on, wipe it on? I'm not a technical person at all and I have tried to read the websites on caring for stone and I am really totally learning disable on these types of subjects because I can't follow at at what they are trying to say. Anything you can do to help me understand this will be greatly appreciated.

I am looking to do something similar in using a polished large tiled very light veining porcelain tile on wall and sane design large tile matte on floor. The actual shower floor will be a stone. My question is I will have a very low lip divider from shower to bathroom floor and the matte finish on the stone is similar to the matte finish on the bathroom floor and more importantly, the two look beautiful side by side so I think I want my lip to be matte not glossy. Any help is appreciated. Can I do the lip inayte to match the floor not the walls? Also I was originally thinking to do all matching matte walls and floor for a natural look but bathroom designer suggested glossy for the walls. Not sure I am sold and have to pick soon. Help!

The use of polished porcelain tile in showers is extremely common. That's almost all you see in fact. Some people like a matte finish - it's just a matter of preference. Porcelain tile is extremely durable and the shine does not wear off unless you deliberately try to dull it with some very caustic chemicals. It does not become dull under normal use. To be 100% sure about what you're buying, ask the vendor about the characteristics of the product you're interested in. Anything with a handpainted design could be less durable.
