After years of hoping and dreaming it's finally time for our master bathroom remodel. I am so excited and yet so in need of advice!

We are replacing tile, tub, shower, fixtures, etc.

The floor size: about 150 sq ft.

Double sink vanity 8 ft

Need to purchase a freestanding tub

Shower is 6.5x3.5

My sink vanity will look something like this:

My inspiration photo for the tile:

This is Cacutta Gold which is much more expensive than the white and gray options like Carrera Venato from Builder Depot.

I want the bathroom to have a relaxing, spa feel. Not cold but warm.

I'd like to mix golds and silver tones. Can I mix the two tiles? Say, Calcutta Gold on the floors and Carrera Venato on the walls?

And if so, then what countertop can I use? For durability I was thinking a white Quartz.. Or?

Please Tell Me Your Thoughts!
