The Quick Answer: Can You Retrofit Soft Close Hinges?
Wondering how to install soft close hinges on existing cabinets without replacing your entire kitchen? The good news is yes — in most cases, you can retrofit soft close hinges yourself in under an hour. The process involves removing your old hinges, selecting compatible replacements, and securing them to the existing hinge cup holes already drilled into your cabinet doors.
Why Melbourne Homeowners Are Upgrading Their Cabinet Hinges
If you’ve ever winced at the sound of a cabinet door slamming shut — especially during early morning kitchen routines — you’re not alone. Across Melbourne’s busy family homes, soft close hinges have become one of the most popular and affordable kitchen upgrades available. They reduce noise, minimise wear on your cabinet doors, and give your kitchen that premium, modern feel without a full renovation.
Beyond comfort, soft close hinges also protect your cabinet frames over time. Repeated slamming can loosen screws, crack timber edges, and cause doors to fall out of alignment. Upgrading your hinges is a simple way to extend the life of your cabinetry significantly.
What You’ll Need Before You Start
Gathering the right tools and materials before you begin will save you multiple trips to the hardware store. Here’s what you’ll need:
- Soft close concealed hinges (35mm cup size is standard for most Australian cabinets)
- A Philips head screwdriver or cordless drill
- A measuring tape and pencil
- A 35mm Forstner drill bit (only if drilling new hinge cups)
- A chisel (optional, for minor adjustments)
- Replacement screws if your existing ones are stripped
Most Australian kitchen cabinets use the European-style concealed hinge system, which means there’s already a 35mm circular cup hole drilled into the back of each door. This makes retrofitting straightforward in the majority of cases.
How to Install Soft Close Hinges on Existing Cabinets: Step-by-Step
Follow these steps carefully and you’ll have smooth, silent cabinet doors in no time.
Step 1 — Remove the Old Hinges
Open each cabinet door fully to access the hinge screws. Unscrew the mounting plate from the cabinet frame first, then unscrew the hinge cup from the door itself. Support the door with your free hand or ask someone to hold it while you work — cabinet doors can be heavier than they look.
Step 2 — Check Hinge Cup Compatibility
Inspect the existing 35mm hinge cup hole in your door. If it’s clean and undamaged, your new soft close hinge cup should drop straight in. If the hole is slightly oversized or damaged, use a small amount of wood filler, allow it to cure fully, then re-drill if necessary.
Step 3 — Attach the New Hinge Cup to the Door
Press the soft close hinge cup into the existing hole and align the screw holes. Drive the screws in firmly but avoid overtightening, which can strip the timber. Most soft close hinges include a clip-on mechanism, so the hinge arm snaps onto the cup once it’s secured.
Step 4 — Fix the Mounting Plate to the Cabinet Frame
Position the mounting plate on the interior side wall of the cabinet at the same height as the original hinge. Use the existing screw holes where possible. If the new plate doesn’t align, mark new positions with a pencil, pre-drill pilot holes to avoid splitting the panel, and screw the plate into place.
Step 5 — Clip the Door Back On and Adjust
Clip the hinge arm onto the mounting plate and close the door gently. Most soft close hinges feature three-way adjustment — height, depth, and lateral — using small screws on the hinge body itself. Take your time here; proper alignment ensures the door sits flush, closes evenly, and the soft close mechanism engages correctly every time.
Common Problems and How to Fix Them
Even with careful installation, a few issues can come up. If your door doesn’t sit flush with adjacent doors, adjust the lateral screw on the hinge in small increments. If the soft close mechanism feels too strong or too weak, some premium hinges include a damper tension adjustment — check the manufacturer’s instructions for your specific model.
If your existing hinge cup holes are not 35mm — common in some older Melbourne homes with imported or custom cabinetry — you may need to source overlay hinges designed for a different cup diameter, or consult a professional for advice. For more information on cabinetry standards in Australia, the Australian Building Codes Board provides guidance on construction and fitout requirements.

When to Call a Professional
DIY hinge installation works well when your existing cabinetry is in good condition and the hinge cups are standard size. However, there are situations where professional help is the smarter choice. If your cabinet doors are warped, your frames are damaged, or you’re dealing with custom overlay configurations, attempting to force a retrofit can cause more harm than good.

The team at Perfect Kitchen & Robes works with Melbourne homeowners across the northern suburbs to deliver beautifully finished cabinetry with hardware that functions flawlessly from day one.

Frequently Asked Questions
What size hinge cup do most Australian kitchen cabinets use?
The vast majority of Australian kitchen cabinets use a 35mm hinge cup, which is the European standard for concealed hinges. Before purchasing replacement soft close hinges, measure your existing cup hole diameter to confirm compatibility. If your cabinets were custom-built or imported, the cup size may differ, so it’s worth double-checking before buying in bulk.
Do soft close hinges work on all types of cabinet doors?
Soft close hinges are compatible with most overlay, inset, and half-overlay cabinet door configurations. The key is selecting the correct hinge type for your door’s overlay measurement — the amount the door overlaps the cabinet frame when closed. Most hinge packaging will specify the overlay range it suits, so check this before purchasing.
How many hinges does each cabinet door need?
As a general rule, doors up to 900mm in height require two hinges, while taller doors — such as pantry doors or floor-to-ceiling cabinet doors — typically need three or more. Using the correct number of hinges ensures the soft close mechanism operates smoothly and the door remains properly supported over time.
Can I install soft close hinges on wardrobe doors as well?
Yes, soft close hinges can be fitted to wardrobe doors using the same process as kitchen cabinets, provided the doors use a concealed hinge system.
