A custom dovetail drawer box with a rectangular notch cut out of the back, open at the rear, so it wraps your sink drain and slides out around it. Baltic Birch or Hard Maple (Select Grade), plain for side mount or notched and drilled for your undermount slide, cut to the 1/32 inch in our Las Vegas shop. Slides sold separately.

Outside box size, cut to the 1/32 inch. Make your slide deduction first: side mount boxes are 1 in narrower than the opening, undermount boxes follow the slide maker's rule.

Description

A real drawer for your sink base

This is a custom dovetail drawer box with a rectangular notch cut out of the back, so it wraps your sink plumbing instead of fighting it. The notch is open at the rear. When the drawer is closed, the drain, trap and trap arm sit inside it. When you pull the drawer open, the pipes leave through the back. You get one tall, full width drawer where your sink base used to have doors.

We build every box in our Las Vegas, Nevada shop, cut to the 1/32 inch and shipped assembled. Built in USA.

Measuring in short

Measure from the left edge of the cabinet opening to the left and right edges of the plumbing that will pass through the drawer. The notch center is the midpoint, minus the slide clearance on the left: 1/2 in for side mount slides, 13/64 in for Blum TANDEM 563 with 5/8 in sides. We suggest about 1 in of room around the pipes, which is a starting point, not a rule: add it to each side of the plumbing span for the notch width, and take it off the distance to the frontmost pipe for the distance from the front to the notch. Then check that nothing over the legs hangs below the top of the box. The full guide is at how to measure plumbing for a U shaped drawer, and box sizes for 30, 33 and 36 in sink bases are at sink base drawer sizes.

We check before we cut

After you order, we check your three numbers against your box size before we cut, and contact you if they do not add up.
