Can I install a pull out drawer organizer if my sink has a garbage disposal?

Yes, but you need to account for the disposal's bulk. Measure the height from the cabinet floor to the bottom of the disposal, and choose a drawer that is shallow enough to fit underneath. You may also need to cut a notch in the drawer bottom for the disposal's bulge, or use a kit with a cutout. Test the clearance with the drawer fully extended to ensure it doesn't hit the disposal.

What is the best way to measure for a pull out drawer under a sink?

Measure the width, depth, and height of the cabinet interior, then subtract 1 inch from the width and 2 inches from the depth for slide clearance. Also measure the height from the cabinet floor to the lowest point of the sink trap, and subtract 1 inch for slide clearance. Use these dimensions to select a drawer or plan a custom build.

Do I need special slides for a heavy load of cleaning supplies?

Yes, use full-extension ball-bearing slides rated for at least 50 pounds per pair. This rating supports the weight of typical cleaning bottles and prevents sagging. For very heavy loads, consider slides rated for 100 pounds or more. Always check the manufacturer's weight limit and distribute weight evenly in the drawer.

Can I retrofit an existing cabinet with a pull out drawer without removing the sink?

Yes, you can install a pull out drawer in an existing sink base without removing the sink. The process involves measuring the interior, installing slides on the cabinet walls, and building or buying a drawer box that fits. Ensure you work carefully around the plumbing, and use a right-angle drill attachment if space is tight.

How to Install an Under Sink Pull Out Drawer Organizer for Awkward Spaces

Assess Your Under Sink Geometry and Plumbing First

Before buying anything, measure the usable space under your sink. Clear out all items, then note the depth from the front edge of the cabinet to the back wall, the width between the side walls, and the height from the cabinet floor to the underside of the sink basin. Pay special attention to the plumbing trap—the U-shaped pipe—because it often sits lower than the cabinet bottom and dictates how tall your pull out drawers can be.

Also measure the clearance around the garbage disposal if you have one, and check whether the water supply lines come in from the floor or the back wall. These measurements determine the maximum width and depth of the drawer slides you can use. A standard rule is to subtract 1 inch from the width and 2 inches from the depth to allow for slide hardware and clearance. If your sink has a deep basin, you may need to choose a shallow drawer (6–8 inches tall) to fit under the trap.

Draw a simple top-down sketch of your sink base, marking the trap location, supply lines, and any other obstructions like electrical outlets or disposal cords. This sketch will guide every subsequent step, from slide placement to drawer layout, and prevents you from buying an organizer that doesn't fit.

Choose the Right Pull Out Mechanism for Your Cabinet

The core of any under sink pull out drawer organizer is the slide mechanism. Full-extension ball-bearing slides are the most common choice because they allow the drawer to pull out completely, giving you full access to the back of the cabinet. Look for slides rated for at least 50 pounds per pair, as you will likely store heavy bottles of cleaner or dish soap.

If your sink base has a curved or recessed floor, consider side-mount slides that attach to the cabinet walls rather than the floor. For narrower openings (under 18 inches), you can use a single slide mounted on one side, but for stability, use two slides—one on each side—even if you have to mount them on plywood strips screwed to the walls. For very awkward corners where the cabinet is not square, a bottom-mount slide with a U-shaped bracket may be easier to align.

Alternatively, consider a ready-made pull out drawer kit with a built-in frame that sits on the cabinet floor. These are easier to install because they don't require precise slide alignment, but they often have a lower weight capacity and may not fit over a large trap. If you have a garbage disposal, look for a kit with a cutout in the bottom tray to accommodate the disposal's bulge.

Install the Slides and Drawer Boxes Step by Step

Start by attaching the slides to the drawer box first, not the cabinet. Most slides have a small lever that allows you to separate the drawer member from the cabinet member. Place the drawer member on the side of the box, align the screw holes with the pre-drilled holes (or drill pilot holes), and secure with the provided screws. Ensure the slides are parallel and at the same height on both sides.

Next, position the cabinet members inside the sink base. Use a level to mark a line on the cabinet walls where the slides will mount, typically 1 to 2 inches above the cabinet floor. Hold the cabinet member against the wall, align the front edge with the cabinet face, and screw it in place. Use a spacer—like a piece of cardboard—under the drawer to ensure consistent clearance, then slide the drawer in and test the action. If it binds, loosen the screws and adjust the slide height slightly.

Once the slides work smoothly, attach the drawer front. Place the drawer in the closed position, then from inside the cabinet, push the drawer front against the face of the cabinet. Mark the screw holes, pre-drill, and attach with the included screws. Adjust the screws on the slides to fine-tune the gap and alignment. For a cleaner look, you can add a false front that matches your cabinet doors, but that is optional.

Lay Out the Drawer Interior to Fit Your Specific Items

After the drawer slides smoothly, focus on the interior layout. The goal is to maximize vertical and horizontal space around the trap. Use removable dividers, small bins, or tension rods to create zones. For example, place tall items like spray bottles near the back or sides, and use the front area for shorter items like sponges or scrub brushes.

If your trap is centered, consider a two-tier design: a shallow upper drawer that sits above the trap and a deeper lower drawer that fits under it. Measure the vertical clearance from the cabinet floor to the bottom of the trap; subtract 1 inch for the drawer slide and 0.5 inch for clearance. Then, divide the remaining height between the upper and lower drawers, leaving at least 2 inches at the top for the sink basin's drain.

Use the sketch you made earlier to mark cutouts in the drawer bottom for the trap and supply lines. For a DIY approach, trace the pipe locations on the drawer bottom, then use a jigsaw or hole saw to create notches. Ensure the notches are large enough for the pipes to move slightly, as vibration from the disposal can cause movement. Alternatively, use a pre-made drawer with a removable bottom panel that you can cut to fit.

Secure the Organizer and Test for Daily Use

Once the drawer is installed and the layout is set, secure the organizer to the cabinet to prevent tipping. Use L-brackets or screws through the drawer front into the cabinet face, and consider adding a child safety latch if you have young children. This is especially important if the drawer is heavy with cleaning liquids.

Test the pull out action with full weight. Load the drawer with your heaviest bottles and pull it open and closed several times. Listen for scraping against the trap or supply lines, and check that the drawer does not sag when fully extended. If you hear noise, adjust the slide screws or add a thin shim under the slide to level it.

Finally, label the zones or add non-slip liners to prevent items from shifting. Over time, check the slide screws for tightness, as vibration can loosen them. With proper installation, your under sink pull out drawer organizer will turn an awkward, hard-to-reach space into a functional storage area for your daily kitchen needs.
