Recommendation to replace marble bathroom countertop with granite

As ferret posted, quartz is non-porous. Therefore isn't going to absorb liquids. Granite stains easily- my daughter bought a house with a nice big kitchen and granite counters- the granite was stained and nothing would remove it.

Aside from that, you can tell your cleaners what you don't want them to do, like drip or set cleaning products on your counters. Most people I know have had to "train" their cleaners to do things the way the homeowner wants. Like they don't need to dump a quarter of a bottle of Fabuloso in a pail of water to wash the floor. :-) And most of my upholstery clients have told me they have forbidden their cleaners from using bleach, because they somehow manage to splash it everywhere, getting bleach stains on everything.
