An under sink bin is a concealed waste system installed inside the cabinet beneath a kitchen sink, typically mounted on pull-out runners. For most Australian kitchens, a 15–20L pull-out bin fitting a 400mm or 600mm cabinet is the best choice. Soft-close, twin-compartment models with quality runners (such as Blum or Hettich) are recommended for families wanting easier recycling separation. Expect to pay $90–$220 for a quality system.
Tired of a bulky rubbish bin taking up valuable floor space in your kitchen? Frustrated by visible bin liners, lingering smells, or recycling piling up on the bench? You're not alone — in compact Australian apartments and busy family kitchens alike, the wrong bin creates daily friction.
An under sink bin solves all of it. Hidden inside the cabinet beneath your sink, the right under sink rubbish bin reclaims floor space, contains odours, simplifies recycling, and instantly upgrades how your kitchen looks and works.
This complete Australian buying guide walks you through every decision: types, sizes for standard Australian cabinet widths (300mm, 400mm, 450mm, 600mm), how to measure around your plumbing, installation, pricing, and the most common mistakes buyers make. We'll also help you avoid the #1 trap — buying a bin that doesn't clear your P-trap.
What Is an Under Sink Bin?
An under sink bin is a compact rubbish bin designed to fit inside the cabinet beneath a kitchen sink, working around plumbing fixtures to maximise concealed storage. Unlike freestanding bins, under sink rubbish bins stay hidden inside cabinetry and typically slide out when the cupboard door is opened.
Modern systems use:
- Pull-out runners (often Blum, Hettich, or Hafele brands)
- Soft-close sliding mechanisms
- Removable inner buckets for easy cleaning
- Single, twin, or triple compartments for recycling
- Optional door-mount brackets that open the bin when you open the cupboard
Because the bin is concealed inside cabinetry, your kitchen looks cleaner, smells better, and stays organised — particularly valuable in Australian apartments, rentals, and smaller kitchens where every square metre counts.
Why Under Sink Bins Are Popular in Australian Kitchens
Australian kitchens are getting smaller and smarter. Apartments, townhouses, and renovated homes all share the same challenge: maximising storage without crowding the bench. In our experience helping thousands of Australian homeowners upgrade their kitchens, kitchen under sink bins consistently rank as one of the highest-impact, lowest-cost upgrades you can make.
For homeowners focused on modern layouts and hidden storage, our guide to space-saving pull-out kitchen bins for stylish homes explores additional ideas for creating a cleaner and more functional kitchen.
Key benefits:
- Space-saving design — Reclaims 0.3–0.5m² of floor space typically lost to a freestanding bin
- Cleaner kitchen appearance — No bulky bin disrupting your kitchen's clean lines
- Better hygiene — Enclosed bins contain odours and keep pets away from waste
- Easier recycling — Twin or triple-compartment systems make sorting effortless
- Child and pet safe — Concealed cabinet bins prevent access to food scraps and sharp waste
- Added resale value — Integrated bin systems are increasingly expected in Australian property listings
For renters, door-mounted kitchen bins offer the same benefits without permanent installation.
Pros and Cons of Under Sink Bins
Like any kitchen upgrade, under sink bins come with trade-offs. Here's a balanced look at the advantages and limitations before you buy.
Pros
- Hidden waste — Rubbish stays out of sight inside the cabinet, keeping your kitchen visually clean
- Saves floor space — Frees up 0.3–0.5m² previously occupied by a freestanding bin
- Cleaner appearance — Maintains the clean lines of modern Australian kitchen design
- Easier recycling — Twin and triple compartments make council-compliant sorting simple
- Better odour control — Concealed cabinet placement contains smells far better than open bins
- Child and pet safe — Waste is inaccessible to curious hands and paws
- Quieter daily use — Soft-close runners eliminate slamming
- Long lifespan — Quality systems typically last 10+ years with minimal maintenance
- Adds resale value — Increasingly expected in renovated Australian properties
Cons
- Requires installation — Pull-out systems involve drilling into the cabinet (not ideal for renters)
- Reduces cabinet storage — The bin frame and runners take up space previously used for cleaning products
- Premium systems cost more — Quality pull-out bins start at $90–$120 vs $20–$40 for basic freestanding bins
- Smaller capacity per compartment — Each bucket is smaller than a single freestanding bin
- Plumbing clearance limits options — P-traps, water filters, and isolation valves reduce usable space
- More frequent emptying for large households — A 15L bin fills faster than a 50L freestanding bin
For most Australian households, the pros significantly outweigh the cons — particularly once recycling and odour control become daily priorities.

Pull-Out Under Sink Bins
The most popular style in Australia and the best choice for most modern kitchens. Mounted on sliding runners — usually bottom-mounted — these bins glide out smoothly when you open the cabinet door. Soft-close runners (Blum and Hettich are the gold standard, with Hafele close behind) deliver the smoothest action and longest lifespan, and are worth considering for any household that opens the bin multiple times a day.
Twin and Triple Compartment Bins
Twin bins house two buckets in one pull-out frame, perfect for separating general waste from recycling. Triple-compartment systems add a third section for food scraps or soft plastics — ideal if you live in a council area with FOGO collection or are committed to full waste sorting. In our experience, more than 70% of Australian homeowners upgrading their kitchens now choose twin-compartment bins over single-bin systems.
Door-Mounted Under Sink Bins
These attach to the inside of the cupboard door and swing open with it. They're cheaper, easier to install (no runners required), and the best option for renters or shallow cabinets where a pull-out won't fit around plumbing. Capacities are smaller, usually 9–20L.
Freestanding Slim Bins
Tall, narrow bins that slot into the empty space beside or behind sink plumbing without permanent installation. Recommended for renters who can't drill into cabinetry, or as a temporary solution before a full kitchen renovation.
Under Sink Bin Sizes for Standard Australian Cabinets
Australian kitchen cabinets follow standard widths: 300mm, 400mm, 450mm, and 600mm. Matching your bin to your cabinet width is the single most important step in buying the right system.
|

Recommended Bin Configuration |
Total Capacity |

40–45L |
|
800mm+ |

These are guidelines for a typical under-sink cabinet with standard Australian plumbing. Always measure your internal cabinet space — pipes, water filters, and isolation valves all reduce the usable area.

Best Under Sink Bins for Small Kitchens
If you're working with a compact Australian apartment kitchen or a 300mm sink cabinet, capacity and footprint are everything. A slim single 10–15L pull-out bin is the best choice for small kitchens because it saves floor space while still offering enough daily capacity for 1–2 people.
Recommended for small kitchens:
- 300mm cabinet width
- 10–15L single bin
- Bottom-mounted soft-close runners
- Lift-off lid for odour control
In our experience, smaller households often regret buying anything under 15L — anything smaller fills daily and becomes a constant chore. If your cabinet allows, lean toward 15L.
Browse compact kitchen bins sized for Australian apartments.
Best Under Sink Bins for Families
For households of 3–5 people, twin 2x 15L or 2x 20L pull-out bins are usually the best long-term investment. They make recycling effortless, reduce how often bins need emptying, and fit standard 400mm and 450mm Australian cabinets.
Recommended for families:
- 400–450mm cabinet width
- Twin compartment, 30–40L total capacity
- Soft-close runners (essential for high-use kitchens)
- Door-mount bracket for automatic opening
- Removable inner buckets for easy cleaning
We've found that soft-close runners last significantly longer in high-use family kitchens compared to budget sliding systems — the extra $20–$40 typically pays off within the first year of daily use. Roughly 8 in 10 buyers who choose budget runners report sticking or sagging within 18 months.
Explore double kitchen bins and twin pull-out systems for family kitchens.
Best Pull-Out Under Sink Bins in Australia
Pull-out bins are the most-requested style in Australian kitchens, and for good reason. They offer better capacity, smoother daily access, and a cleaner integrated look than door-mounted alternatives.
What to look for in a quality pull-out bin:
- Bottom-mounted runners — Support more weight and work with door-mount brackets
- Soft-close mechanism — Quieter, smoother, longer-lasting
- Steel frame construction — Outlasts plastic frames in daily use
- Removable buckets — Lift-out buckets make cleaning 10x easier
- Door-mount compatibility — Lets the bin open with the cupboard door
- Australian liner fit — Bucket should fit standard AU 27L or 36L liners
Most homeowners prefer pull-out systems once they've used one — the convenience is hard to give up. Browse the full range of pull-out kitchen bins sized for Australian cabinetry.
Soft-Close Under Sink Bins
Soft-close runners are increasingly the default expectation in Australian kitchen renovations. The mechanism uses a damper that slows the drawer just before closing, eliminating slamming and reducing wear on the cabinetry.
Why soft-close is worth considering:
- Quieter daily operation (no slamming, especially helpful in open-plan homes)
- Longer cabinetry lifespan — soft-close protects MDF and hinge points
- Premium kitchen feel that matches modern integrated Australian joinery
- Better resale value in Australian property markets
Soft-close kitchen under sink bins are particularly recommended for households with kids who tend to slam drawers, or anyone renovating with longevity in mind. Brands like Blum, Hettich, and Hafele dominate the premium runner market, with German engineering from Hailo and Ninka leading the high-end integrated space.
Under Sink Recycling Bins
With Australian councils rolling out FOGO (Food Organics and Garden Organics) collection across more areas, recycling bins are no longer optional — they're essential infrastructure. Twin and triple-compartment under sink systems make council-compliant sorting effortless.
Best recycling configurations:
- Twin 2x 15L — General waste + recycling (most common)
- Twin 2x 20L — Higher capacity for entertainers and larger families
- Triple 3x 15L — General waste + recycling + food scraps/FOGO
- Triple compartment with separate FOGO bucket — Ideal for full council compliance
Twin or triple under sink rubbish bins are usually the best long-term investment if recycling matters to your household. In our experience, around 60% of buyers who choose single bins return within 12 months wanting to upgrade to twin systems.
How to Choose the Right Under Sink Bin (Household Size Guide)
Capacity should match how much waste your household generates daily. In our experience, under-sizing is the most common buyer regret — a bin that fills in 24 hours becomes a chore within a week.
|
Household Size |
Recommended Capacity |
Best Configuration |
|
1–2 people |
10–20L |
Single pull-out or door-mount |
|
3–4 people (small family) |
20–30L |
Twin pull-out, 2x 15L |
|
5+ people (large family) |
30L+ |
Twin 2x 20L or triple compartment |
|
Heavy cooks / entertainers |
40L+ |
Large twin or triple, soft-close |
If you cook from scratch most nights or have a household composter, lean toward the larger size — most homeowners prefer the extra capacity once they have it.
How to Measure Around Sink Plumbing (Step-by-Step)
The #1 reason under sink bins get returned is that buyers measured the cabinet width but ignored the plumbing. Follow these five steps before purchasing any under sink bin.
- Measure internal cabinet width. Open both doors and measure between the inside walls of the carcass — not the outside dimensions.
- Measure internal depth. Measure from the back of the cupboard door (when closed) to the rear wall.
- Measure usable height. Measure from the cabinet floor up to the lowest point of your sink, P-trap, or waste pipe.
- Note the P-trap position. Most P-traps sit centred behind the sink; some are offset. A bin needs clearance to slide past it.
- Account for isolation valves and water filters. Under-sink water filters can steal 80–150mm of usable depth.
Australian standard plumbing clearance: Leave at least 30–50mm of buffer on all sides for runners and door clearance.
Key Features to Look For
A checklist to compare any under sink rubbish bin before you buy:
- Soft-close runners — Quieter, smoother, longer-lasting. Worth the extra $20–$40.
- Bottom-mounted vs side-mounted runners — Bottom-mounted (like the ELITE Domestique and Hafele systems) supports more weight and works with door-mount brackets.
- Removable inner bucket — Lift-out buckets make cleaning 10x easier.
- Door-mount bracket compatibility — Lets the bin open automatically when you pull the cupboard door.
- Material — Powder-coated steel frames last longer than plastic; stainless steel buckets resist odours best.
- Lid type — Lidless bins inside enclosed cabinets work fine; lidded buckets add an extra odour barrier.
- Australian bin liner fit — Check the bucket fits standard AU liner sizes (27L or 36L are most common).
Price Guide: How Much Do Under Sink Bins Cost in Australia?
Pricing varies widely based on capacity, runner quality, and brand. Here's what to expect in 2026:
|
Tier |
Price Range (AUD) |
What You Get |
|
Budget |
$25–$60 |
Basic door-mount or freestanding, plastic build |
|
Mid-range |
$60–$150 |
Quality pull-out, steel frame, soft-close |
|
Premium |
$150–$280 |
Twin/triple compartment, Blum or Hettich runners, door-mount kit |
|
High-end integrated |
$280–$600+ |
German engineering (Hailo, Ninka, Hafele), Servo-Drive electric opening |
For most Australian households, the $120–$200 mid-range bracket delivers the best value — proper soft-close runners, twin compartments, and a 10+ year lifespan.
Installation Tips for Under Sink Bins
Most under sink bin systems are designed for DIY installation, but careful prep saves frustration.
Before you start:
- Clear and clean the cabinet floor completely
- Confirm your screws won't pierce plumbing or wiring
- Check that the cabinet door opens fully (some bins need 95°+ to clear)
During installation:
- Mark all screw points with a pencil before drilling
- Use a spirit level — uneven runners cause sticking
- Hand-tighten first, then finish with a screwdriver (power drills can over-tighten and strip MDF)
- Test the full slide action before fitting the door-mount bracket
- For door-mount systems, allow the bin to find its natural alignment before locking the bracket
For custom Australian cabinetry or stone benchtops, a cabinet maker or kitchen installer is worth the $80–$150 callout fee.
How to Keep Your Under Sink Bin Odour-Free
Enclosed bins can trap smells if neglected. These habits keep yours fresh:
- Empty daily during Australian summers, every 2–3 days in winter
- Use a quality bin liner that fits properly (loose liners leak)
- Wipe the inner bucket weekly with warm soapy water
- Sprinkle bicarbonate of soda in the base between liner changes
- Run liners with a few drops of eucalyptus oil for natural odour control
- Wash buckets monthly with diluted white vinegar to kill bacteria
If smells persist, check for trapped food scraps under the runners or at the back of the cabinet.
Common Mistakes to Avoid
After helping thousands of Australian customers choose bins, these are the mistakes we see most:
- Measuring only cabinet width. Always check internal depth and plumbing clearance.
- Choosing the cheapest runners. In our experience, bargain runners fail within 12–18 months in a busy kitchen.
- Buying too small. A 10L bin in a family kitchen needs emptying daily and becomes a constant frustration.
- Ignoring the door-mount option. Door-mounted brackets are a small extra cost but transform daily use.
- Forgetting recycling needs. Most buyers wish they'd gone twin or triple within six months.
- Skipping soft-close. Once you live with soft-close, basic runners feel cheap.
Are Under Sink Bins Worth It?
For most Australian households, the answer is a clear yes. An under sink bin delivers daily benefits that easily justify the $90–$220 mid-range investment:
- Reclaims 0.3–0.5m² of floor space
- Hides waste from view
- Reduces kitchen odours
- Makes recycling effortless with twin/triple compartments
- Adds resale appeal to your Australian property
They're particularly worth considering for apartments, small kitchens, families with kids or pets, and any home where the kitchen is part of an open-plan living space.
Frequently Asked Questions
What size under sink bin do I need for a family of 4?
A family of 4 typically needs 20–30L of total capacity. The best configuration is a twin pull-out with 2x 15L buckets — one for general waste, one for recycling — fitted in a 400mm or 450mm cabinet. This handles roughly two days of waste between emptying and simplifies recycling separation.
Can under sink bins fit around plumbing?
Yes. Most modern under sink rubbish bins are designed to slide past standard P-traps and waste pipes, particularly bottom-mounted pull-out systems where the bin sits low in the cabinet. Always measure your internal cabinet height from floor to the lowest pipe, and allow 30–50mm of clearance for runners and door movement.
Are pull-out under sink bins better than door-mounted ones?
Pull-out systems are generally the best choice for daily use because they support larger capacities (up to 56L), offer smoother soft-close action, and last longer. Door-mounted bins are cheaper and easier to install, making them ideal for renters or shallow cabinets where a pull-out won't fit around plumbing.
How do you clean an under sink rubbish bin?
Remove the inner bucket and wash with warm soapy water weekly. Wipe down the frame and runners monthly with a damp cloth. Once a month, use diluted white vinegar or a mild disinfectant on the bucket to kill bacteria. Always dry fully before refitting the liner to prevent mould.
What's the best under sink bin for a 600mm cabinet?
A 600mm cabinet fits the widest range of options. The most popular configuration is a twin 2x 20L pull-out (40L total) with soft-close runners and door-mount bracket. For full recycling sorting, a triple-compartment 3x 15L system fits comfortably and gives you separate bins for general waste, recycling, and food scraps.
How much does an under sink bin cost in Australia?
Quality under sink bins cost between $90 and $220 in Australia for a mid-range pull-out system with soft-close runners. Budget door-mounted bins start around $25–$60, while premium German-engineered systems with Blum, Hailo, or Ninka components can exceed $400. Most households find the $120–$200 range offers the best long-term value.
Can I install an under sink bin in a rental kitchen?
Yes. Choose a door-mounted bin or a freestanding slim bin — both require no permanent drilling into cabinetry. Door-mounted bins hang on the inside of the cupboard door using brackets that can be removed without damage. Always check your lease before installing anything that requires screws.
Do under sink bins reduce kitchen smells?
Yes, significantly. Concealed cabinet bins contain odours far better than open freestanding bins because the cupboard acts as a secondary barrier. Pairing your bin with a fitted lid, quality liners, and weekly cleaning keeps the kitchen virtually smell-free even during Australian summers.
What is the standard size of an Australian sink cabinet?
The most common Australian sink cabinet widths are 600mm, 800mm, and 900mm externally, with 300mm, 400mm, 450mm, and 600mm being standard bin-compatible widths internally. Always measure the internal carcass width — not the external cabinet dimension — when shopping for an under sink bin.
Are double under sink bins worth it?
Yes, for most Australian households. Twin-compartment systems make recycling effortless and only cost $20–$50 more than single bins. With Australian councils rolling out FOGO and stricter recycling sorting, twin or triple bins are increasingly a long-term necessity rather than a luxury.
Final Thoughts: Ready to Upgrade Your Kitchen?
Choosing the right under sink bin starts with measuring your cabinet properly and selecting a system that matches your household size, plumbing layout, and recycling needs. The right pull-out bin saves space, hides rubbish, contains odours, and improves kitchen organisation for the next decade.
In summary:
- For small kitchens and apartments: Slim 15L pull-out in a 300mm cabinet
- For families: Twin 2x 15L or 2x 20L pull-out with soft-close runners
- For full recycling sorting: Triple-compartment system in a 600mm cabinet
- For renters: Door-mounted 15L bin (no permanent installation)
