Lots of people are opting for higher bathroom countertops these days. On average people are taller so it makes sense. Go for whatever height is most comfortable for you. If your husband is concerned that it might impact resale it wont.

I'm 5'2" and the vanity height in the master is 37" in this house. It's comfortable for me to use, including the sink (undermount).

The powder room vanity at my SILs is tall, I'm not sure of the height in inches. She has a vessel sink installed - with that added height, the sink in her powder room is awkward for me to use. Really awkward.

Many, many threads on this forum where Houzzers have weighed in on this topic. No one right answer - except what is comfortable for you both. I agree that resale is not an issue. For what it's worth, most of our clients opt for a finished vanity height of 36" in a bathroom for adults.

I’m 5’ 3.5” and would never go back to a lower height vanity if I could avoid it. Much prefer our 36” tall vanities. Miss mine when we visit my parents.

we are going to put ours at 38"-39" (we are 6'4" and 5'9")

If the height is comfortable for both then it’s a decision for both to decide . Now on the other hand as you are remodeling the question also would be does it fit with the overall design concept that you have in mind.

Even though you are going to be living in your house for a number of years (hopefully), you still need to think about the eventual resale of your home. Too high will eliminate short buyers and too low will eliminate taller buyers.

depending if you have young or children or not i would go with a higher vanity. if you have little children though you might want to stay with the lower one.
