I used kitchen cabinets in my master bath. The only thing to remember is that they are a little taller and deeper than your standard bath vanity. I don't mind it, and I'm only 5'4" but some people may think it feels too tall or not have the space for the depth.

It's not uncommon, especially in families with taller people. We used standard kitchen height cabinets - not necessarily "kitchen" cabinets - in all of our bathrooms. Two of the four bathrooms have the same cabinets as the laundry room. All bathroom cabinets are on feet. My installer cut off the base of the cabs when they arrived and bought extra stain/glaze from the cabinet company (Jim Bishop Cabinetry) so it would match.

We have a powder room off the kitchen with no cabinets, so they don't match the kitchen. The kitchen cabinetry was custom. Below is a link of three of our bathrooms. I also used two three drawer dressers with bookcases sitting on top in our master closet. They are on sep. walls and also on legs.

I also have a kitchen cabinet in my bath. I'm tall and appreciate the extra height, but I don't think this would be a good option if the bath is used by children.

We didn't necessarily use kitchen cabinets in the bathrooms, but we had all the bathroom cabinets (except the master bath) built to kitchen height. We didn't do it in the master because we used vessel sinks on top of the vanities.

I wanted kitchen height but not depth in the master, but my contractor had my CUSTOM CABS cut down to standard height thinking that it was a mistake!!!

AAAARRRRGGHHH!!!!

I am on my way over there now to see what can be done....

We did this but adjustments had to be made for the increased depth. Standard bathroom countertops are not deep enough. We had a simple shelf made to hide the gap, which turned out to be one of the most useful things we did in the entire remodel!

We love the extra height it gives. Even my 5' mother liked the taller height, which surprised me.

Brookhaven makes both kitchen and bath cabinets. I needed a pantry-type cabinets that were three inches shallower than standard kitchen cabs, so was able to order them without paying a custom fee. Their depths come in three-inch increments, as are widths, I believe. Height may be the same way. Don't assume kitchen places/people know about bathroom cabinet lines. The first two Brookhaven places I went to did not. Hope this helps.

As kitchenobsessed mentioned, many of the cabinet companies offer bathroom specific cabinets. They may be slightly different in specs than the kitchen cabinets so just check the specs. I also used "bathroom base cabinets"from Schuler in my kitchen to create a hutch. I wanted 21" deep base cabinets and the bathroom cabs came in 21 and 18" depths so they were perfect and I didn't have to pay a custom fee. Same height and door styles, etc as my kitchen cabs. The only difference was that the shelves inside were only 1/2 shelves.

Thanks so much Kitchenobsessed (and everyone else)....we are getting Brookhaven cabs for the kitchen and I asked our KD about using another one for the bathroom and he did not mention this at all to me.
I know we need one 36 inches across, but what is the standard size for depth for bathroom vanities?

allison your bathrooms look great btw! Love the mirrors!

I used a kitchen cab in my basement remodel, I'm just ok with it- doesnt look as furniture as I'd like.

I am doing first floors now, and debating using cabs or trying to find an antique dresser to convert for something interesting.

Standard bathroom vanity depths are 18", and more commonly 21"--the raised height vanities tend to be 21" deep.

You can definitely work with Brookhaven either way. For me it was putting 21" deep cabinets in my kitchen island and 13" deep (their standard upper cabinet depth) up on a toekick for the back of the island.

bumping this in case anyone else has pics to share.
Thanks everyone so far....

my bathroom cabinet is kitchen cabinet height and I hated it. Because the cabinet is high so is the mirror. I am short. Need I say more?
