Broken drawers
Drawer bottom fell out: fix it or replace the box?
For anyone whose kitchen or bathroom drawer bottom dropped, bowed or pulled loose from its groove, or whose box split open at a corner, and who is deciding whether to fix it or replace the box. Also for the shop that gets the call. Here is what actually failed, what is worth fixing, and what to order if it is not.
Quick answer. A drawer bottom falls out because it was never captured on every side: stapled to the underside, or set in a groove on three sides with a loose back. On every box we build, the bottom sits in a groove cut into all four walls, so it has nowhere to drop to. A bottom that slipped out of a sound groove can often be slid back and pinned; a split panel, a broken groove, or a stapled bottom re stapled into the same holes is a temporary fix at best, and a replacement box is usually the better call. Gritly builds every replacement box, standard or custom, with the bottom captured in a groove on all four walls, built to your exact size in our Las Vegas shop.

Why do drawer bottoms fall out?
The bottom is a thin panel, and it only stays put if every edge of it is held. Pull a failed drawer out and look at how the bottom meets the walls. That tells you which of three builds you have, and why it let go.
- Stapled to the underside. The panel hangs below the box on fasteners driven up into the end grain of thin plywood. Load it, and the staples pull free or the thin edge splits, so the bottom drops straight out.
- Grooved on three sides, loose at the back. The panel sits in a groove at the front and both sides, but the back is only butted on or tacked. The unsupported back edge is the weak point: it works loose, bows down, or drops when that one fastening gives.
- Captured in a groove on all four sides. The panel sits in a groove cut into the front, back and both side walls, so every edge is supported before the dovetailed corners are even glued. This is our build. It cannot drop out, because it is inside the box, not hanging from a fastener.
| Build | How the bottom is held | How it fails |
|---|---|---|
| STAPLED UNDERSIDE | Fasteners only, driven up from below into the panel edge | Staples pull out of thin plywood, or the edge splits, and the panel drops |
| GROOVE, THREE SIDES | Front and both sides captured; the back is only butted on or tacked | The loose back edge works free, bows or drops first |
| GROOVE, FOUR SIDES | Front, back and both sides all captured, dovetailed corners lock the walls | Cannot drop out; the panel is supported on every edge |
Can I glue or re staple a drawer bottom back in?
Sometimes, and it depends on what actually failed. A bottom that simply slipped out of a sound groove, with the front, back and both sides still intact, can usually be slid back into place and pinned at the back so it cannot walk out again. That is a real fix, not a stopgap.
A bottom that split, bowed, or came out of a groove that is itself cracked or chipped is a temporary fix at best. The panel or the groove is already compromised and will not hold under the next load. A stapled bottom nailed or re stapled into the same holes rarely holds either, since those holes are already enlarged in thin plywood. In any of those cases, a replacement box is the honest answer, not another round of glue.
Is the box broken or just the bottom?
The bottom and the box fail separately, and the fix is different for each. Check the corners and the front before you decide the whole box is gone.
| WHAT YOU SEE | WHAT IT MEANS |
|---|---|
| The bottom sags, but the corners are tight | The bottom itself has given out. The box is sound; see what to pick below for a thicker bottom. |
| A corner has opened up | A joint has failed. On a stapled or doweled box that joint will not go back together; on a dovetailed box it is rare, and it is what our warranty covers if we built it wrong. |
| The front is loose or rattles on its own | Often just the screws holding the drawer front to the box. Tighten them before assuming the box itself is bad. |
| The box racks or wobbles as a whole | The corner joints have failed throughout. No adjustment fixes a racked box; this is a replacement. |
| The drawer will not close, or stops short | Usually not the box at all. See why won’t my drawer close for the five slide and obstruction causes. |
Should I replace one drawer or the whole run?
One failed box in an otherwise sound set is a one box job. Measure it and order a custom replacement matched to the old box’s outside size, or a standard size if it lands on the grid.
Several opened corners across a stapled or doweled set usually means the whole run is the same age and the same build, so the others are not far behind. A new set is often the better buy, but that is your call to make, not ours to push. Replacement drawer boxes covers ordering one box or several.
If you are replacing several boxes at once, measure and order each one to the outside size of the opening it goes in, rather than copying a single measurement across the run. Openings in the same kitchen are not always identical even when the fronts look the same. Keep the same slide type and side thickness across the set so the fronts land flush and level once everything is back in.
What to measure before you order
What you measure depends on whether the old box still holds its shape. Either way, the number you send us is the one we cut to.
| Your situation | What to measure |
|---|---|
| OLD BOX STILL HOLDS ITS SHAPE | Outside width, depth and height, the same box we build to the 1/32 in. The measuring guide walks all three. |
| BOX IS WARPED, SPLIT OR GONE | The clear cabinet opening and your slide type. The slide sets the deduction: side mount is the opening minus 1 in; undermount follows the runner maker’s own figure. See side mount or undermount slides explained. |
| EITHER WAY | You give us the outside box size. We build exactly that; there is no hidden deduction on our side. |
What to pick in the configurator
Four choices decide the box: species, bottom, sides, and your size. The bottom comes captured in the groove on every single build, no matter what you pick.
Pick the box wood
On the custom drawer box, choose Baltic Birch (Our Standard) or (Select) Hard Maple. The bottom choices update to match.
Choose Drawer Bottom Thickness/Wood Type
1/4 in is standard on every box. Step up to a 1/2 in bottom, such as 1/2" Thick Baltic Birch Bottom or 1/2" Thick Hard Maple(Select) Bottom, for a wide drawer carrying real weight. Either way the bottom is captured in the groove on all four sides, never stapled on.
Choose Drawer Side Thickness
5/8" Thick Drawer Sides (Our Standard) fits most replacements. 1/2" Thick Drawer Sides (Thin) opens up room inside a narrow drawer; 3/4" Thick Drawer Sides (Thick) stiffens a wide, heavy one. See drawer side thickness for the full breakdown.
Enter your size and order notes
Width, depth and height are the outside of the box, cut to the 1/32 in. Add your old box’s slide brand, or any match details, in the order notes field.
Already know it is the box? Build a custom replacement cut to your exact width, depth and height, or start from a standard size if your old box lands on the grid. Every box ships dovetailed, with the bottom captured in the groove on all four sides.
Questions
Why did my drawer bottom fall out?
It was not fully captured. Most failures are a bottom stapled to the underside of the box, where the fasteners pull free of thin plywood under load, or a bottom set in a groove on three sides with a loose back, where the unsupported back edge works free. On our boxes the bottom sits in a groove on all four walls, so it has nowhere to drop to.
Can you fix a drawer bottom that fell out?
Sometimes, temporarily. A bottom that slipped out of a sound groove can usually be slid back into place and pinned at the back. A bottom that split, bowed, or came from a groove that is itself broken, or a stapled bottom nailed back into the same holes, will not hold for long. The lasting fix is a replacement box.
How is a dovetail drawer bottom attached?
It is captured in a groove cut into all four walls of the box, front, back and both sides, so every edge of the panel is supported before the corners are even glued. The interlocking dovetail joints at each corner then lock the four walls together, and the bottom has no fastener to pull free of.
Should I use a 1/4 in or 1/2 in drawer bottom?
1/4 in is standard and right for most kitchen and bath drawers. 1/2 in is for wide drawers carrying real weight, pots and pans, files, a pantry pull out, at the cost of 1/4 in of interior height. See drawer bottom options for the full breakdown by material.
Can I replace just the drawer bottom?
On our boxes, no. The bottom is captured in the groove, so replacing it means replacing the box as a unit, built to your exact size. On a stapled box, a loose panel can be re stapled, but that fix is only temporary, since the fastener holes are already worn.
How do I measure a broken drawer for a replacement?
If the box still holds its shape, measure it outside to outside: width, depth and height. If it is warped, split or gone, measure the clear cabinet opening and make the slide deduction yourself, 1 in narrower for side mount, or per the runner maker for undermount. Our measuring guide walks both cases.
How long does a replacement box take?
Baltic Birch ships in about 2 to 4 days and Hard Maple (Select Grade) in about 4 to 5 days, both build time before the label prints, not delivery. Trade portal orders ship in about 7 days for either species.
Is a dovetail box worth it over a stapled one?
For a drawer that gets opened every day, yes. A dovetailed box locks tighter at the corner every time you pull it, while a stapled or doweled box works looser. See dovetail vs stapled drawer boxes for the full comparison. We build every box, standard or custom, with true interlocking dovetails at all four corners.
How do you fix a drawer bottom that falls out?
If the groove is sound and only the panel slipped, push it fully back into the groove on all four walls, then pin or glue the back edge so it cannot work loose again. If the panel is split, the groove is cracked or chipped, or it was only ever stapled on, that fix will not hold. Gritly’s replacement boxes capture the bottom in a groove on all four walls from the start, so it is held on every side.
How do you reinforce a drawer bottom?
Pin or glue a bottom that slipped out of a sound groove back into place at the back edge; that stops it from walking out again under load. A bottom that is only sagging, not out of its groove, is reinforced by stepping up to a 1/2 in bottom on your next order rather than patching the one you have. Gritly builds every bottom captured in a groove on all four walls to begin with.

Fix it once, in the box
A bottom that is only stapled on, or loose at the back, will fail again the same way. Order a dovetailed replacement with the bottom captured in the groove on all four sides, cut to the 1/32 in and built in our Las Vegas shop. Custom boxes start at $46.99.
