Which Natural Stone is Best for Outdoor Countertops?
When selecting a natural stone for your outdoor kitchen countertop, it’s important to choose one that can withstand extreme weather conditions, UV exposure, and temperature fluctuations, unlike indoor countertops. The use of natural stone is popular due to its durability, hardness, and aesthetic appeal. However, not all stone varieties perform well outdoors. You must therefore choose your natural stone for your outdoor bar counter or BBQ worktop based on factors such as porosity, maintenance, and stain and scratch resistance.
Choosing the right natural stone is essential when deciding which material to use for your outdoor countertops. Some stones, such as granite and quartzite, are known for their durability, while others, like marble, require more care. Let this guide help you explore five of the most popular natural stones for outdoor countertops, along with their pros, cons, and suitability for outdoor kitchens.

Marble Slabs for Benchtops
Marble has always been synonymous with luxury and elegance, which is why it is often chosen for benchtops both indoors and outdoors. Marble is a naturally occurring stone known for its beautiful veining and unique formations, adding a touch of class to any outdoor kitchen.
Benefits of Marble for Outdoor Countertops
- Aesthetic Beauty: This is one of the main reasons homeowners opt for marble slabs for their benchtops. Each marble slab is unique, with variations in tonalities that add personality and elegance to outdoor environments.
- Heat Resistance: With thermal and anti-adhesive properties, marble is an excellent choice for outdoor BBQ worktops and cooking areas. Unlike synthetic materials, marble won’t warp or crack when exposed to high temperatures, making it perfect for outdoor kitchens.
- Availability in Different Colours and Finishes: Marble comes in a wide range of shades, from monochromatic whites and greys to darker, more dramatic tones like green and black. It is available in polished, honed, or leathered finishes, and can be customised to suit both aesthetic and functional requirements.
Challenges of Using Marble for Outdoor Benchtops
- Porosity and Staining: One major drawback of marble is its porosity. It is prone to absorbing moisture, which leads to staining and discolouration over time. Acids like lemon juice, vinegar, and wine can etch and leave dull marks on the surface. Regular sealing is required to minimise this risk.
- Sensitive to Weather: Marble can be sensitive to prolonged exposure to rain, snow, and extreme temperatures. In areas with frequent freeze-thaw cycles, water may penetrate the stone, resulting in cracks or surface damage.
- Maintenance Needs: Marble requires regular upkeep to retain its fresh appearance. Unlike granite or porcelain, marble requires regular cleaning with pH-neutral stone cleaners, immediate spill removal, and occasional resealing to avoid potential damage.
While marble offers elegance and beauty, its suitability for outdoor bar countertops depends on how much maintenance you’re willing to provide.
Granite Slabs for Benchtops
Granite is one of the most popular natural stones for outdoor kitchen countertops due to its durability and resistance to sun rays, rain, and temperature changes. Formed from volcanic activity, granite is a hard igneous rock that is perfect for outdoor environments.
Benefits of Granite for Outdoor Countertops
- Remarkable Durability: The hardness of granite makes it resistant to scratches, cracks, and chips. Granite slabs are durable for benchtops, unlike softer stones like marble and dolomite, offering excellent performance in outdoor spaces for years.
- Weather and Heat Resistance: Granite is exceptional at withstanding extreme temperatures. It does not suffer significant damage from exposure to direct sunlight, heavy rain, or freezing conditions, unlike many other natural stones.
- Low Maintenance: Granite requires minimal maintenance compared to more porous stones. Sealing it regularly increases its stain, moisture, and UV resistance, making it an ideal choice for outdoor BBQ worktops or high-traffic cooking areas.
Challenges of Using Granite for Outdoor Benchtops
- Regular Sealing: While granite is less porous than marble, it still requires sealing periodically to prevent moisture absorption and staining. However, with proper care and regular maintenance, granite can last for many years outdoors.
- Heavy Weight: Due to its density, granite needs to be installed on a solid base to ensure stability and support. Professional installation is crucial for the long-term durability of your outdoor countertop.
If you want an outdoor countertop that can handle the weather and won’t corrode over time, granite is the perfect option for your home.
Dolomite Slabs for Benchtops
Dolomite is a rising star in the world of natural stone, offering a balance between marble and granite. It has the aesthetic appeal of marble but is harder and more resilient, making it suitable for outdoor bar countertops and dining areas.
Benefits of Dolomite for Outdoor Countertops
- Marble-like Appearance with Added Strength: Dolomite has delicate veining and soft colours, similar to marble, but is less porous and more resistant to scratches.
- Relatively Weather-Resistant Compared to Marble: Dolomite is less durable than granite but more weather-resistant than marble. With appropriate sealing, it can handle moderate exposure to sun, wind, and rain, making it a viable option for outdoor kitchens.
- Affordability: Dolomite is often more affordable than high-end marble and quartzite, providing a cost-effective option for homeowners who want a luxurious appearance without the hefty price tag.
Challenges of Using Dolomite for Outdoor Benchtops
- Porosity and Need for Sealing: Though less porous than marble, dolomite still needs to be sealed regularly to prevent moisture seepage and staining.
- Low Heat and Scratch Resistance: Dolomite is more durable than marble but not as hard as granite or porcelain. Heavy impacts or direct exposure to extreme temperatures can cause damage to the surface.
For those who love the aesthetics of marble but need something more durable for outdoor countertops, dolomite is an excellent substitute. However, regular maintenance and sealing will be required to maintain its beauty outdoors.
Quartzite Slabs for Benchtops
Quartzite is one of the most durable natural stones used for outdoor countertops, combining beauty with strength. Unlike engineered quartz, which uses resin and crushed stone, natural quartzite is formed under intense pressure, giving it excellent resistance to weather and regular use.
Benefits of Quartzite for Outdoor Countertops
- Weather and UV Resistant: Some stones lose their shine when exposed to direct sunlight, but quartzite slabs retain their colour and luster even in outdoor conditions, ensuring they look the same after years of use.
- Waterproof and Stain-Resistant with Proper Sealing: Quartzite is more resistant to moisture than marble and dolomite, but sealing it ensures that it remains non-porous and stain-resistant.
- Available in Various Colours and Patterns: Quartzite comes in various colours, including whites, greys, beiges, blues, and greens, making it a sophisticated choice for outdoor spaces.
Challenges of Using Quartzite for Outdoor Benchtops
- Requires Sealing: Similar to other natural stones, quartzite requires periodic sealing to maintain its stain and moisture resistance. However, it is more durable than marble or dolomite.
- Higher Price Range: Due to its strength and natural beauty, quartzite is typically more expensive than other stone options. However, its longevity makes it a worthwhile investment.
Quartzite slabs are perfect for those who want a stone that is both luxurious and durable, making them ideal for outdoor bar tops, BBQs, and kitchen countertops, where longevity and low maintenance are essential.
Porcelain Slabs for Benchtops
Porcelain is an engineered, non-porous material that has become a top choice for outdoor countertops due to its durability, low maintenance, and modern appearance. Unlike natural stone, porcelain is manufactured at extremely high temperatures, making it highly resilient to the elements.
Benefits of Porcelain for Outdoor Countertops
- No Sealing Needed: Porcelain slabs are non-porous and waterproof, meaning they don’t require sealing. They are fully waterproof and stain-resistant, making them ideal for outdoor kitchen countertops exposed to rain or humidity.
- Scratch and Heat Resistance: Porcelain is resistant to high temperatures without cracking or discolouring, making it a solid choice for outdoor BBQ worktops. It’s also highly scratch-resistant, ideal for food prep areas.
- UV Resistance: Due to its high-density nature, porcelain does not fade or discolour from sun exposure, ensuring that your outdoor countertop stays vibrant over time.
- Low Maintenance: Unlike natural stones that require sealing and regular care, porcelain is one of the easiest materials to manage, requiring only soap and water for cleaning.
Challenges of Using Porcelain for Outdoor Benchtops
- Minimal Colour and Pattern Variation: While porcelain comes in various colours and finishes, it lacks the natural veining and variation found in marble, granite, or quartzite.
- Can Be Brittle: Although durable, porcelain can chip along the edges if heavy items are dropped on it.
If you’re looking for a low-maintenance, waterproof, and durable countertop for your outdoor kitchen, porcelain slabs are the ideal choice. They are perfect for outdoor countertop bars in high-humidity or high-exposure areas.
Conclusion
Natural stone is a great option for outdoor countertops, but you must choose wisely between the options available. Granite and quartzite are highly durable options that can withstand rough conditions with minimal maintenance. Marble and dolomite, while offering unmatched beauty, require more care. Porcelain provides an ultra-durable alternative with bespoke designs and minimal upkeep.
If you want an outdoor kitchen countertop that will last, choose high-quality natural stone so your space remains both functional and aesthetically pleasing for many years. Whether you prioritise durability, style, or ease of maintenance, the right choice will enhance your outdoor living experience.
