It would be good if you could tell us the actual height of the vanity that you like. Vanities used to be 32" high, but now they are usually 36" high. I expect that you can still find some that are 32" high, but if you use a floating vanity, you can install it at the height you want. Just google floating vanities and you'd find lots of sources.

I just finished a remodel of my bathroom and went from regular low vanities to a high counter for the sink and a much lower counter where I installed a grooming sit down area in lieu of the second sink

I am also short but once I got used to the higher height I really prefer it - especially for washing my face. With the lower vanity - even with my short height - there was much more distance between my hands and face so there was a lot of spillage when rinsing my face.

I was never comfortable leaning over a counter to view myself closer in the mirror which is why I deliberately opted for a sit down portion where I can sit comfortably with both the wall mirror for long views and a mirror on the counter with magnification option for close up work.

If I wanted to stand at the bathroom counter for grooming, I would get a really good mirror and attach it to the wall - the kind with telescopic arm so that I can have the mirror exactly the distance and height I wanted. However, based on my experience with my current higher bathroom sink, I really like the functionality of a higher height sink. I wouldn't however want a higher height counter with a vessel sink but that was moot for me because I hate vessel sinks anyway :-).

I have 1950s vanities and love them. I forget how much I love them until visiting places with tall "new" ones. I think I skimp on brushing my teeth when I have to do it on tiptoes. (I did that just this past weekend.)

If it's just the mirror and not the sink that irritates you (they're useless for detail work behind a tall vanity), get the mirror on an arm Helen describes. They're great. Get one anyway, and get the electrical in place for it so you can get one that lights up. You do get more storage in a taller vanity.

But if the sink height itself bothers you, it's worth finding a lower vanity, or getting a vanity that allows the sink to be positioned towards the very front edge of the counter so it's easier to get one's face over it.

I'm kind of short too and really dislike the higher vanities. My body doesn't seem to bend at a place that makes leaning over the higher sink possible. My worst issue is using a water pick. I have a sit down vanity, but I never use it because I really need a sink constantly.

For me, 34" is ideal, but we are putting a wall-hung vanity in my brother's bathroom. He wants it at 36", but of course it could be hung much lower. This is the one he has selected, and our contractor said it would work for his bathroom.
