Is marble is a good material for bathroom vanity Vanity Tops?  

Yes, for a bathroom marble countertops are fine. You still need to learn how to clean marble properly (which is not hard) and once you do you’ll find it’s no big deal and you’ll have very few if any issues.

If you are careless and neglectful, then you’ll have some problems with marble bathroom countertops or say if it is primarily used by young kids.

But most marble is not very absorbent and does not stain easy like you may have read. And polished marble is nearly stain-proof. So, stains are not common. 

A marble countertop in the bathroom simply does not get the use and abuse and isn’t constantly exposed to acids like in the kitchen, so really a marble vanity top is pretty easy to care for.
