Jan Moyer, 1) I want to order online because I haven't found a local cabinetmaker that doesn't want at least $7,000 for this 59" x 22.5" vanity. That's just too steep for me...especially after spending so much $$ on a kitchen remodel. 2) I want to order online because I can't seem to get any help from kitchen and bath businesses in my area (very small town) that want to deal with ONLY ordering 1 vanity. They like to do full kitchens and more expensive jobs. 3) My custom kitchen cabinet maker hasn't gotten back to me for a bathroom vanity bid. I'm not sure he's around anymore. 4) Why not MDF? Because I like stain/glaze on real wood. MDF is only paintable. I haven't found a company that provides sealed plywood as the box...I've only found companies that provide particle board. My current vanity is particle board and when we had a water issue by the toilet, it swelled the base of my vanity and the wood veneer split in multiple places... 5) My current vanity is short, 32". That's why I want a taller vanity... Yes, I was thinking of simply ordering a kitchen cabinet base (like for an island) to use as a vanity. I like all drawers in the bathroom, no doors if possible. 6) I like "matchy"...and since we're remodelling two bathrooms, I'd like the house to feel cohesive with the same cabinetry throughout.

you can see all the Ikea vanities in store and it's close to NYC. As for Home Depot and Lowes, it's more hit and miss but you can use the question and answer feature on their sites. Just be mindful that anyone can respond so manufacturer responses are likely better. Also, as Elunia mentioned, you may find luck in the outer boroughs where space isn't as high a premium for "regular" retailers.

Your picture is a wood door that is stained Depending on your budget find a good local custom cabinet shop or a high quality semi-custom. I have wood stained vanities in my bathroom and there are no issues. I am not spray them with water and my bathroom is well ventilated and has a great fan that operates based on ambient humidity level. FWIW you don't want a humid bathroom whatever the materials are as you will get mold and mildew on any surface such as teh tiles and the sheet rock walls. I think you need to physically visit good cabinet stores to see what is available in semi-custom or custom and price those out. FWIW I have custom stuff done by a local company. I looked at lots of aspirational photos and decided I wanted rift sawn white oak wood. I then worked with him to decide the exact store. Everything about these was custom as the doors were special designed and the internal configuration was as well.

Why not put in electric in floor heating in the bathroom uder tile . It works really well and keeps the space toasy all the time and wonderful to put bare feet on. Usually toe kicks are elctric so should not be ahuge deal if remodelling the bathroom. The other option is a heater / towel warmer they use them a lot in Britain
