Thank you @User. I will check with them.

Hacking IKEA is fast and easy and you'll get professional results. This floating vanity cabinet doesn't exist in a catalog and is 2 IKEA's hacked into 1:

You can modify any IKEA cabinet in any way, just realize you lose the preset cam/lock locations, so you will be fastening almost as if you were building from scratch with plywood. With today's prices on plywood, sometimes modifying RTA cabinets as a hybrid scratch-built is cheaper.

Instead of cutting a base cabinet, use a 15 inch tall 24 inch deep refrigerator cabinet for the bottom (i think available in 30 or 36 inches wide). I'd mount it on a 2x4 or other base instead of wall hanging it. There are a few projects out there with this approach if you search on Google. The 15 inch tall fridge cab with the single door can have a drawer installed in it but it's not the default. Get the tall Maximera drawer and skip the horizontal door hinges.

@V On The Lake I didn't realize I could put drawers in those refrigerator cabinets. I'll have to look that up! I still don't think it would work for me if I go with five lockers but I could make it work if I decide to do six.

@Joseph Corlett, LLC I'm looking at the Godmorgon for the bathroom in this project, and I'd wondered about installing them right next to each other. Thanks for the photo!
