Dear Customer,

You don't need to switch the countertop because we sell just the vanity cabinet only below:

Please let me know if you have further questions.

Thank you,

Yanny/Luxvanity

Do you have a solid surface white top that is available for sale to go with this cabinet?

Dear Customer,

Unfortunately we don't sell the countertop only due to high risk of damage. I am sorry about that.

Thank you,

Yanny/Luxvanity

Do you know if the marble on the top is quite busy? Is there any way you could specify choosing the most plain/simple least variegated for the one that I purchase?

Dear Customer,

For this particular model, the countertop comes with White Carrera marble only. Unfortunately, I can't describe the way it looks because item ships directly from the manufacturer's warehouse.
