Hello all,

I’ve been commissioned to build a 96” bathroom vanity. Rock maple face frame, inset doors and drawers. Customer is painting it themselves and pouring a concrete top. Customer is the owner of the local construction lumber company, and he’s a good friend and knowledgeable in all woodworking, not just construction. Although he has requested ‘paint grade’, he will appreciate proper joinery and methods.

With that said, I don’t have a set way that I build the backs to my cabinets, I usually just see what is most appropriate for the build, ie. if it’s intended as a permanent installation, standalone piece of furniture, and if the rear needs to be kept open for piping or whatever.

I usually use wooden blocks for my drawer slides in faceframe cabinets, but this piece has so many that it wouldn’t be reasonable. So, as I’m a self taught woodworker who takes each build as it comes, I wanted to ask you all what the recognized pro-approach to this would be?

Would you essentially have a rear faceframe, with 1/4” ply in dados, and you use rear [under? side?] mounted drawer slides? Or have the back open and just position cleats where you know you’ll need them for, again, rear mounted slides?

Other option is to just double up the interior walls so that your dividers are always flush with the face frame, but that would add a ton of wood and weight.

WWYD? Thanks

Edit

My preferred option would be to have dados running vertically down the back of my dividing walls, after construction I’d slide in 1/4” panels (except where plumbing is located). But obviously you can’t screw rear mount brackets into 1/4” panels. Are there plastic plugs for this use?

Blum makes rear brackets for their slides that screw to the cabinet back. I’d go with undermount for the appearance and for those the slide will attach to the face frame and bracket.

Personally, I’d use blocks. You only need two per slide and they don’t have to be but two or three inches long. Also, I’d spend the extra dollar to get the fully adjustable front locking devices (like the Blum T51.1901.20, but be sure to get the appropriate one for your application).

I do all of my business with https://www.woodworkerexpress.com. Their prices are good and the support staff can make sure you get the right parts for your build.

If we’re talking rear mount, what blocks do I need? I was only referring to blocks where you need a strip from front to back where you have a face frame and are using side mount drawer slides.

Are you building this as 1 cabinet? Will it fit into the bathroom?

Customer has a clear shot and can get the whole thing in there with ease. No narrow hallway. So it’s one solid piece.

What you need to do is download the TANDEM plus BLUMOTION Concealed Runners for Wood Drawers Planning Tool from blum.com. It’s an Excel spreadsheet that is dynamic, so you just answer some questions, enter the values they ask for and it will tell you the model of drawer slide you need. After that, download the installation instructions for that slide and follow them. There will be different mounting options, and you can choose the best for your situation.

I would probably do it something like this.
