I'm not a designer, but from my own experience, I can say that it's better to use marble. But it depends on the style of the rest of your rooms and your preferences. Anyway, you can navigate to this website and found more advantages of using marble and order it. I used this site to buy marble countertops when I had a renovation in my own house.
Both are the best materials. I will recommend you to consult with Labour Hire Brisbane. They are providing labour services and they can also guide you which one is suitable for your studio. Choosing between marble and wood is not a piece of game. They will guide you according to the surrounding environment.
