My wife and I are about to remodel one of our bathrooms, a small 5x7 bathroom with a tub, toilet, vanity.

We know very little about hardware, and we're getting conflicting information and would love to know a bit more.

Tile (floor). We chose a marble tile, however one of the contractors we spoke to said we shouldn't it because it's far too slippery. Is this really something we should be concerned about? Neither my wife and I have ever heard of tiles that are too slippery for the bathroom.

Tub. We can't seem to get a clear answer as to which is better - cast iron or acrylic. We've heard cast iron is too expensive for a guest bedroom, and that acrylic is too soft and flexible...

Any thoughts will help us as we continue to investigate what will ultimately work for our needs.
