When designing a kitchen, the choice of benchtop material is crucial—not just for aesthetics and durability but also for indoor air quality and health. Many benchtop materials contain substrates, sealants, resins, or adhesives that can off-gas harmful chemicals.


Here’s a guide to the best non-toxic benchtop options and how to ensure a safe kitchen environment.


Natural Stone: Granite, Marble & Quartzite

Natural stones like marble and quartzite are excellent low-tox kitchen benchtop options because they are natural stones that do not contain synthetic resins or adhesives. When correctly sealed with a zero-VOC, PFAS-free sealer, they have minimal off-gassing and contribute to better indoor air quality.


Granite & Quartzite

  • Granite and quartzite are some of the most durable natural stone options.

  • Many varieties do not require sealing, making them a low-maintenance, non-toxic choice.

  • If sealing is necessary, opt for a zero-VOC, PFAS-free sealer to maintain indoor air quality.

  • Certain dense granites, like Ubatuba, often do not need any additional treatment.


Marble

  • While elegant, marble is more porous than granite and may require sealing to prevent staining.

  • Natural oil-based sealers, such as walnut oil, can be used to avoid synthetic chemicals.

  • It’s essential to maintain marble regularly to prevent etching and discolouration.


Soapstone

  • A highly dense, naturally non-porous stone that does not require sealing.

  • Typically treated with mineral oil or a natural wax to enhance its deep colour.

  • Some varieties contain trace asbestos, so sourcing from a trusted supplier is crucial.



Engineered Stone & Solid Surface

Silica-based engineered stone has been banned in Australia due to serious health risks, particularly silicosis from respirable crystalline silica dust during fabrication. As a result, silica-free engineered stone is emerging as a safer alternative, offering a non-toxic, durable, and low-maintenance benchtop option—provided it is free from harmful resins and VOC emissions.


Always check for Greenguard Gold or Global GreenTag certifications to ensure indoor air quality safety.


Quartz (Engineered Stone)

  • A mix of ground quartz, pigments, and polymer resins.

  • While quartz benchtops claim to be fully cured and non-toxic, some minor off-gassing may occur.

  • Choosing a reputable brand with third-party testing for low emissions is recommended.


Solid Surface (Corian, etc.)

  • Made from acrylic or polyester resins combined with natural minerals.

  • Seamless and easy to clean, but may contain petroleum-based compounds.

  • Opt for brands with certified low-VOC emissions to ensure that indoor air quality remains uncompromised.


Eco-Friendly & Alternative Options

Sintered Stone (Porcelain Benchtops)

  • Composed of natural minerals and free from resins or binders.

  • Highly resistant to stains, scratches, and heat.

  • Does not require sealing, making it a hassle-free, non-toxic choice.


Paper Composite (PaperStone, Richlite)

  • Made from recycled paper and natural resins.

  • Durable, waterproof, and food-safe.

  • Develops a patina over time, which adds to its aesthetic appeal.


Recycled Glass & Concrete

  • A mix of crushed glass with cement or resin.

  • Brands like IceStone and Vetrazzo offer sustainable, low-VOC options.

  • Ensure that the binding agent is free from harmful chemicals.


Concrete

  • Customisable and provides a modern aesthetic.

  • Requires sealing to prevent staining; choose a non-toxic, zero-VOC sealer.


Wood & Other Natural Materials


Solid Wood & Butcher Block

  • Provides warmth and natural beauty to a kitchen.

  • Requires regular oiling; natural options like walnut or mineral oil are best.

  • Sustainably sourced hardwoods are preferable for longevity.


Tadelakt (Lime-Based Plaster)

  • A traditional Moroccan lime plaster that is naturally waterproof.

  • Free from synthetic chemicals and offers a unique, seamless finish.

  • Requires natural soap-based treatments to maintain water resistance.


Tile (Ceramic, Porcelain, Natural Stone)

  • Highly customisable and heat-resistant.

  • Use a non-toxic grout and sealer to ensure a healthy environment.

  • Requires regular maintenance, particularly the grout lines.


Stainless Steel, Copper, & Zinc

  • Naturally antimicrobial and durable.

  • Do not require sealing or chemical treatments.

  • Provide a sleek, industrial aesthetic with minimal maintenance.

Choosing the Right Benchtop for a Healthy Home

When selecting a benchtop, consider:

  • Material Composition: Avoid petroleum-based resins and synthetic additives.

  • Sealers & Adhesives: Choose zero-VOC, non-toxic options to maintain air quality.

  • Maintenance & Longevity: Opt for materials that require minimal treatment to avoid unnecessary chemical exposure.


By making informed choices, you can create a stylish and safe kitchen for your family’s health. Whether you prefer the elegance of natural stone, the eco-consciousness of recycled materials, or the warmth of wood, there is a non-toxic benchtop solution for every home.
