Kitchen Sinks

The Best Kitchen Sinks Online for Australian Kitchens 

Buildmat’s kitchen sinks range, including premium 304 grade stainless steel, is designed for homes in Australia that value both style and practicality. Each piece is built for everyday use, combining durable materials with finishes that stay looking new no matter how busy your kitchen gets.

Stainless Steel Kitchen Sinks Designed for Everyday Living

Your kitchen sink is one of the most used features in your home and it needs to work as hard as you do. That’s why stainless steel sinks remain the go-to choice for Australian kitchens. A stainless steel sink offers durability, easy maintenance, and a timeless look that suits both modern and traditional spaces. Whether you're prepping dinner or stacking dishes, the right kitchen sink can make all the difference.

Brushed stainless also hides water marks better than polished stainless in a busy kitchen, which is something customers often appreciate the most. It's worth considering if wiping down the sink every day isn't your priority.

Kitchen Sinks for Every Layout and Lifestyle

From small city apartments to busy family homes, we offer a wide range of new kitchen sinks to suit your space. Choose a single bowl kitchen sink including right hand bowls, for compact areas or upgrade to a double bowl kitchen sink if you need more room to multitask. Our range includes undermount kitchen sinks and topmount kitchen sinks, all designed to maximise benchtop space and streamline your workflow with deep bowls.

Kitchen Sinks Online in On-Trend Colours

Buildmat’s kitchen sinks come in finishes that suit every style and surface. Stainless steel remains the top choice for its strength and versatility, while white sinks and grey sinks add a soft, contemporary touch. For a bold contrast, black sinks and gunmetal sinks finishes bring modern edge to minimalist kitchens. If you prefer warmth and luxury, explore brushed brass gold or brushed stainless steel designs.

Why Choose Buildmat Kitchen Sinks? 

All of our stainless steel kitchen sinks are handmade using 304-grade high-quality stainless steel — designed for strength, sound reduction, and everyday durability. Each sink includes a basket waste and comes watermark certified to meet Australian plumbing standards. Whether you’re upgrading your kitchen, laundry, or butler’s pantry, you’ll find a sink built to last. If you’re looking for the perfect sink that blends form, function, and long-term reliability, Buildmat’s kitchen sinks deliver every time.

Award-Winning Kitchen Sinks, Built to Last

At Buildmat, we design with purpose — combining performance, style, and durability in every product. Our commitment to quality was recognised globally when we won a Product Design Award at the 2020 Architecture Masterprize, taking out top honours in the kitchen category. Whether you're choosing a butler sink, granite sink, or a sleek undermount sink, that same attention to detail applies across our full kitchen and laundry range.

1.5mm Premium Thickness for Everyday Strength

Sink thickness isn’t just about weight — it’s about quality. Our kitchen tubs are made with 1.5mm thick stainless steel, giving you greater durability, better sound absorption, and a more solid feel. Whether it’s a compact single bowl or a generous double bowl sink, you’ll notice the strength every time you set down a pot or stack dishes in the drainer.

Our sinks are designed to suit both stone and laminate countertops, with styles including undermount sinks, topmount, and flushmount options to complement any layout.

Precision Handmade Sinks with Built-In Confidence

Each of our handmade kitchen sinks is crafted with precision. Unlike mass-produced pressed sinks, our designs are welded by skilled professionals to maintain full thickness across every wall. The result? Clean lines, strong corners, and a finish that’s built for daily life.

You’ll find options across a wide variety of styles and materials — from classic stainless steel sinks to statement finishes like fireclay sinks or on-trend farmhouse sinks. Many include thoughtful kitchen sink accessories like strainers, colanders, and cutting boards — all designed to make your space work harder for you.

Made for Australian Kitchens

All of our sinks are built to meet Australian plumbing standards and include watermarked basket wastes. With long-lasting finishes and full warranty coverage, you can be confident your sink is made to handle the demands of everyday life — and then some.

What to Check Before You Buy a Kitchen Sink

Benchtop cutout and cabinet width 

Measure your existing cutout before selecting a replacement sink - the new sink's outer dimensions must clear the cutout, and the cabinet below needs to accommodate the bowl depth. Most 600mm-wide cabinets suit a 500-600mm sink; double bowl formats typically need a 750mm+ cabinet. If you're going larger, confirm the cabinet carcass can take the weight, particularly for granite and fireclay sinks.

The question we get most from Melbourne renovators: "can I go larger than my existing sink?" Usually yes, if the benchtop is stone and the cabinet is wide enough. The constraint is almost always the cabinet width, not the benchtop cutout - benchtops can be recut, cabinets can't easily be widened. Measure the internal cabinet width before upsizing.

Undermount vs topmount for your benchtop material 

Undermount sinks require a waterproof solid-surface benchtop - stone (natural or engineered), solid timber with sealant, or similar. They cannot be undermounted into laminate. If your benchtop is laminate and you want the clean look of an undermount, a flushmount is the closer option. Topmount sinks work across all benchtop types and are the straightforward choice for a like-for-like swap.

Bowl depth and your plumbing set-out 

Deep bowl sinks (250mm+) look great but need more clearance under the bench for the waste pipe and P-trap. In renovations where the waste is already fixed in the floor or wall, a very deep bowl can create a tight angle on the drain. Check the clearance between your benchtop underside and the waste outlet before specifying a 250mm bowl - particularly in apartments with limited sub-floor space.

Tap holes 

If your kitchen mixer mounts through the benchtop rather than on a tap landing, your sink won't need tap holes. If you want the tap on the sink itself, confirm the hole position and size matches your mixer before ordering. Most of our range is available with and without tap holes - check individual product specs.

304 vs 316 stainless steel 

304-grade stainless is the standard for indoor kitchen sinks and handles everyday use, cleaning products, and humidity well. 316-grade (marine stainless) is specified for outdoor alfresco kitchens where the sink is exposed to UV, rain, and salt air. Don't use a 304-grade sink outdoors long-term - it will corrode at the weld points.

Watermark certification 

All sinks sold at Buildmat carry Watermark certification - the Australian compliance standard for plumbing fixtures. This is a plumber's requirement at installation and also relevant for insurance and building inspections.
