How Much Does a Stone Benchtop Cost?

Stone benchtops are a popular choice in Australian homes for their durability, natural beauty, aesthetic appeal, and ability to transform the overall look of a kitchen. Whether you are renovating or building new, understanding the cost of stone benchtops is an important step in planning your kitchen budget. Prices vary depending on the material, thickness, installation, and region. In this guide, we break down what you can expect to pay for different types of stone benchtops in 2025 and how to make the best decision for your project.

Average Stone Benchtop Cost in Australia

The cost of stone benchtops in Australia ranges between $400 to $600 per square metre for engineered stone and $700 to $2,000 per square metre for natural stone, including installation. The final price depends on the type of stone, kitchen size, cut outs for sinks and appliances, edge profiles, and overall installation complexity.

A new stone kitchen benchtop can cost anywhere from $4,000 to $8,000 fully installed in an average-sized kitchen. Larger kitchens, premium materials, or intricate installation jobs may push the price higher.

Factors That Influence Stone Benchtop Prices

Several key factors influence the total cost of stone benchtops:

• Material Type: Natural stone is generally more expensive than engineered stone, but offers a unique look. Granite and marble are among the most premium choices.
• Slab Size and Thickness: A thicker slab (e.g. 40mm) will cost more than a 20mm option and also requires more labour for installation.
• Edge Profile: Straight edges are usually standard, but decorative profiles like bullnose or shark nose add to the price. Different edge profiles are available to match various kitchen designs.
• Cut Outs: Integrated sinks, cooktops, and other cut outs require precision work and increase the overall cost.
• Installation Complexity: A straight, simple layout costs less than complex installations involving corners or waterfall ends.
• Location: Prices may vary slightly between Sydney, Melbourne, Brisbane, and Perth due to local demand, labour costs, and access.
• Benchtop Area: Larger surfaces naturally increase cost due to additional material and installation time.

Comparing Stone Benchtop Prices Around Australia

Although material costs are generally consistent, installation costs and delivery charges can vary across states:

Types of Stone Benchtops

1. Engineered Stone

Made from crushed quartz and resin, engineered stone is non porous, stain resistant, and durable. It offers a uniform appearance and comes in a wide range of colours and finishes. Brands like Caesarstone and Smartstone dominate this category. Engineered stone is made from ground quartz or granite mixed with polymer resin or cement. It is also heat resistant to a degree and suits most Australian kitchen designs.

• Price: $400 to $600 per square metre
• Maintenance: Low
• Durability: High

2. Granite

Natural granite is highly hard wearing, scratch resistant, and heat resistant. Each slab features unique natural variations in pattern and colour. It is ideal for heavy-use kitchens but may require sealing annually to protect against stains.

• Price: $700 to $1,500 per square metre
• Maintenance: Requires sealing
• Durability: Very high

3. Marble

A luxurious natural stone, marble offers unmatched beauty and a premium finish. It is softer and more porous than granite, making it prone to scratches and stains if not properly maintained. Marble is better suited to bathrooms or low-traffic kitchens.

• Price: $800 to $2,000 per square metre
• Maintenance: High (requires sealing)
• Durability: Medium

4. Limestone and Sandstone

These stones bring a soft, earthy tone to kitchens. While appealing, they are less durable and more susceptible to wear than granite or quartz, and they require sealing annually to maintain their look. Limestone and sandstone are comparable in durability to marble.

• Price: $700 to $1,800 per square metre
• Durability: Medium
• Best for: Bathroom vanities or feature areas

Installation Costs for Stone Benchtops

Stone benchtop installation cost depends on job complexity, access to the kitchen, and number of trades involved. Expect:

• Basic install: $700 to $1,200
• Complex install (waterfalls, corners): $1,200 to $2,500+
• Cut outs: $100 to $300 per cut out
• Edge profiles: $50 to $120 per linear metre depending on style

Hiring a trained professional is essential due to the weight and fragility of stone slabs. When hiring a stone benchtop installer, ask questions to ensure they are suitable for your project. Installation must be coordinated with your kitchen designer before cabinetry is finalised.

Maintenance and Sealing

Engineered stone requires minimal maintenance, making it a cost effective and practical choice. Simply clean with warm water and mild detergent.

Natural stone (granite, marble, limestone, sandstone) must be sealed every 12 months to prevent stains. Sealing costs range from $20 to $50 per square metre. Regular sealing ensures the longevity and appearance of your benchtop.

Regular maintenance helps retain the aesthetic appeal and functionality of your stone benchtops.

Comparing Stone with Other Benchtop Materials

Laminate benchtops are the most affordable, with patterns that imitate stone at a fraction of the cost. Timber brings warmth, while stainless steel suits contemporary kitchens. Engineered stone remains the most popular choice for balancing cost, durability, and design flexibility.

How to Save on Stone Benchtop Costs

• Get quotes from at least three stonemasons. Comparing quotes from multiple stonemasons can provide insights into costs and quality of service.
• Choose a standard thickness like 20mm to avoid excess slab use
• Limit cut outs where possible
• Opt for engineered stone if on a budget
• Look for remnant slabs for small kitchens or bathrooms
• Time your project around promotional periods

Conclusion

Stone benchtops elevate any kitchen with their timeless look, durable surfaces, and wide range of colours and textures. Whether you choose the elegance of marble, the durability of granite, or the practicality of engineered stone, your final cost will depend on a mix of factors including material, slab size, installation complexity, and your kitchen layout.
