I have tumbled travertine (basically a form of marble) in the master bedroom and a marble mosaic in the master bath. It is higher maintenance. It stains and it wears differently in different areas. I am not doing natural stone in my new home. There are some fantastic tiles now that mimic all the stones, and a good quality porcelain tile will be very durable. Some ceramic wall tiles are "weaker" but I have had excellent luck with porcelain tile. Granite floors. Sure. But as people have said they also require maintenance like periodic sealing etc. In a house that size you don't want a different kind of floor in every room. I would stick to one or perhaps two types of floor tile in the main rooms. You can get away with additional types on walls in the bathrooms but I would keep the floors consistent. As far as cost goes, there is a very broad range of tiles and stones. In my shopping I have found some very good high quality floor tiles for reasonable prices. Stone has priced out higher...at least the ones I have looked at. Good luck!

The ceramic vitrified tiles should have less maintenance. Granite, depending on which you choose, often has to be sealed. Not all granite, but several different varieties require sealing. The sealing should occur every year or so. The vitrified tiles should require very little maintenance other than mopping and the occasional deep cleaning of the grout (when ever it starts to bother you, you do a deeper clean). Some grouts do not require sealants, others do. I would say the granite has the higher maintenance costs on a year to year basis. Of course, granite can be refinished (stone mason comes out and regrinds and then reseals the floor) which ceramic tiles do not have this option. Not many people choose to have their stone floors refinished (can be expensive and very messy) but it granite does give you the option.

You can use natural stone like marble for floor but do not use granite for floor at all as it is very slippery when wet. As for tiles do not go for glazed vitrified tiles for the floor for the same reason. ( floor becomes slippery once wet and may cause mishap) Go for ceramic anti skid tiles that are specially meant for bathroom floor. For wall tiles you can use whatever you like and then decide over the matching anti skid floor tile/ marble. Double charged vitrified tiles are usually used for flooring in rest of the house.
