i wouldnt mix 2 highly patterned or busy stones but you could certainly mix stones. If you have one that has a busier look, mix it w something simpler. Good luck

I think it could work, especially in a larger bathroom! I like your second picture.

I think it depends on the bthroom so maybe post pics of your space and the 2 choices . I think it would only really work in a huge bathroom. IMO order a vanity without the top and match it for a nicer and simpler look. I think too many finishes in a bathroom are just too many.

It works great in the first one.

It's okay in the second one although a plainer white on the tub would be better.

The vanity looks like it is there by accident in the third one

It looks like they used leftovers in the fourth one.

I haven’t picked materials yet…went to my first showroom today, so I need to get m6 plan down! My tube is on the opposite wall from my vanities. My thought was dramatic marble tub surround (chunky/veiny marble) with a more solid looking vanity material (non marble for easier maintenance). I have about 5’ between the edge of my tub and the vanities.

Quite common for a tub deck to be different than the countertops. It can often times create a better visual when they differ. On the flip side, being the same, it can tie a room together. Depends on the elements in the room as well as the scale of the room.

No single answer applies 100% of the time.
