Yes, installing a deep drawer insert for pots and pans is a very achievable DIY project for most homeowners. It doesn't require a building consent, no licensed trades are involved, and the right insert can transform a chaotic kitchen drawer into a well-organised storage space. The main things to get right are measuring accurately, choosing a compatible insert, and fitting it securely.
What Is a Deep Drawer Insert?
A deep drawer insert (sometimes called a pots-and-pans organiser or drawer divider system) sits inside an existing deep kitchen drawer — typically 150 mm to 300 mm in depth — and creates compartments or pegs to hold cookware upright and stable. They're available in timber, stainless steel, coated wire, and plastic, and are designed to suit standard cabinet drawer widths (commonly 450 mm, 500 mm, 600 mm, and 900 mm).
These inserts are different from replacing the drawer itself or modifying the cabinet carcass — they simply drop or fix into the existing drawer box.
Tools and Materials You'll Need
- Tape measure and pencil
- Combination square
- Cordless drill and drill bits
- Screwdriver (Phillips and flat)
- Rubber mallet (optional, for snug-fit inserts)
- The insert kit itself (with any included fixings)
- Sandpaper (fine grit, if trimming a timber insert)
- Safety glasses
You can find a good range of drawer inserts and the tools above at Bunnings or Mitre 10.
Step-by-Step Installation Guide
1. Measure Your Drawer Carefully
Before purchasing anything, measure the internal dimensions of your drawer box — width, depth (front to back), and height (inside depth). Don't measure the cabinet opening; measure the inside of the drawer itself. Write these down and take them with you when shopping.
2. Choose the Right Insert
Match the insert to your measurements. Most inserts are designed to either:
- Drop in (friction or gravity fit — no fixing required), or
- Screw fix to the base or sides of the drawer box.
Check the manufacturer's specifications carefully. Some inserts are adjustable or can be trimmed to width. If you're buying a timber insert and it's slightly oversized, you can carefully sand or plane the edges for a snug fit.
3. Empty and Clean the Drawer
Remove everything from the drawer and give it a good clean. Check that the drawer slides smoothly on its runners and that the base is solid — a damaged drawer base may need repair before fitting an insert, especially if you're adding the weight of cast iron pots.
4. Dry-Fit First
Place the insert into the drawer without fixing it. Check it sits flat, doesn't rock, and allows the drawer to open and close fully without catching on the cabinet frame. This is the step most DIYers skip — don't.
5. Fix the Insert in Place
If your insert requires screwing down, use the fixings provided. Pre-drill pilot holes to avoid splitting the drawer base, especially if it's MDF or thin plywood. Don't overtighten — snug is enough. For drop-in inserts, a small bead of non-permanent adhesive (like a furniture pad or rubber grip mat underneath) can stop the insert shifting during use.
6. Test Under Load
Once fitted, load the insert with your pots and pans and open and close the drawer several times. Check nothing is catching, the drawer runners aren't straining, and the insert stays put.
Weight Considerations — Don't Overload Your Runners
This is the most commonly overlooked issue. Cast iron cookware is heavy, and standard soft-close drawer runners are typically rated to 25–40 kg per drawer. Check the weight rating stamped on your existing runners (often on the side of the runner mechanism). If you're stacking heavy cast iron pans, you may be close to or over that limit. Upgrading to heavy-duty runners (rated 50 kg or more) is also a DIY job, though it requires removing the drawer and re-drilling fixing holes — take your time and use a level.
Do I Need a Building Consent?
No. Fitting an insert inside an existing drawer is minor maintenance and does not require a building consent. It doesn't affect the structure, weathertightness, or any building systems. For general guidance on what work requires consent, MBIE Building Performance is the authoritative source — always confirm with your local council if you're ever unsure.
Tips for a Professional Finish
- Timber inserts look great in timber-lined drawers — consider finishing raw timber edges with a matching stain or a food-safe oil.
- Wire or stainless inserts are easier to clean and suit modern kitchens well.
- If your drawer box itself is damaged, warped, or the base is delaminating, it's worth fixing that first — an insert won't compensate for a poorly functioning drawer.
- Label or group your cookware zones (lids, pans, baking trays) before fitting so you design the layout around how you actually cook.
When to Call a Professional
While the insert itself is DIY-friendly, call a qualified cabinet maker if:
- Your drawer box is damaged and needs replacing or rebuilding.
- You want to add a new deep drawer where one doesn't currently exist — this involves modifying the cabinet carcass and may require joinery skills and, depending on scope, a building consent check.
- Your existing runners are failing and you're not confident replacing them.
- You want a custom-built timber insert made to measure for an unusual drawer size.
A skilled cabinet maker can also advise on the best insert system for your specific cookware and cabinetry. You can find qualified local cabinet makers on tradedirectory.co.nz.
