2025 Guide to Kitchen Benchtops: Acrylic Solid Surface, Engineered & Sintered Stone

Planning a kitchen renovation? One of the most important decisions you’ll make is choosing the right kitchen benchtop material. It’s not just a surface – it’s the centrepiece of your kitchen’s design and day-to-day functionality. 

As South Australian renovation specialists, we help Adelaide homeowners select kitchen benchtops that suit lifestyle, budget and current safety standards. 

In 2025, the top contenders for best kitchen benchtop materials in Australia include: 

• Acrylic Solid Surface 
• Silica-Free Engineered Stone 
• Sintered Stone 

Let’s explore the pros and cons of each to help you choose the right surface for your renovation project. 

Acrylic Solid Surface (e.g. Corian) 

Made from acrylic resin and natural minerals, this non-porous surface is hygienic, repairable and can be moulded into custom shapes with seamless joins – making it a standout for modern kitchen renovations in Australia. 

Advantages: 

• Seamless joins for large islands and integrated sinks 
• Easy to repair scratches and surface marks 
• Hygienic and non-porous – ideal for food preparation 
• Flexible design for curves and sculptural profiles  

Considerations: 

• Sensitive to heat (heat-resistant but not heatproof) 
• Softer surface – more prone to scratching 
• Deep burns or gouges may require professional resurfacing 
• May be seen as less premium than stone-based surfaces 

Best for:
Homeowners seeking a smooth, seamless look with design flexibility and a low-maintenance finish. If you’re after a kitchen benchtop that offers customisation and easy cleaning, acrylic solid surface is a smart choice.

Engineered Stone – Crystalline Silica-Free (e.g. Caesarstone)

In response to Australia’s 2024 ban on engineered stone with more than 1% crystalline silica, manufacturers now offer silica-free kitchen surfaces that are both safe and stylish. These materials retain the durability and visual appeal of traditional engineered stone, minus the health risks. 

Advantages: 

• Durable and highly resistant to stains and scratches 
• Uniform finishes that replicate the look of natural stone 
• Wide colour and pattern options 
• Easy to clean and maintain 
• Fully compliant with Australia’s new silica safety regulations 

Considerations: 

• Not heatproof – sudden temperature changes can cause damage
• Avoid using abrasive reagents or aggressive cleaning agents  
• Some surfaces may fade under prolonged UV exposure 
• Always check your installer is using certified silica-free products 

Best for:
Homeowners who want a safe, modern alternative to traditional stone. If you’re upgrading your kitchen and want the best kitchen benchtop material that meets health and safety standards, silica-free engineered stone is a top option.

Sintered Stone (e.g. Dekton) 

Sintered stone is one of the most advanced kitchen benchtop surfaces available in Australia. Made by compressing natural materials under extreme heat and pressure, it creates an ultra-durable, hygienic surface without the silica-related risks of traditional engineered stone. 

Advantages: 

• 100% heatproof – safe for hot pots and pans 
• Extremely resistant to scratches, stains and UV light 
• Non-porous and bacteria-resistant 
• Sustainable manufacturing with recyclable content 

Considerations: 

• Must be installed by experienced professionals due to its density 
• Higher upfront cost reflects long-term performance 
• Limited edge detailing compared to acrylic 

Best for:
Busy households or entertainers who need a hardwearing kitchen surface that handles everything from hot pans to high traffic. It’s also ideal for outdoor kitchens in Australia, thanks to its UV and weather resistance. If you’re investing in a premium kitchen renovation, sintered stone is one of the best kitchen benchtop materials in 2025.
