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.

Saranya that's a bold choice. You may want to tone it down with aqua palette.

Kendra, Do you know why it is like this. Can the underlying plumbing not be changed to get away with this. Please share the measurements to get a fair idea on this

These are some of the colors that I liked.
