Choose with confidence

Sandstone or porcelain?

The right choice depends on whether you value natural variation or maximum consistency and low maintenance.

Natural sandstone

Best for natural character and a more traditional stone feel.

  • Every slab has unique colour and texture
  • Naturally riven, tactile surface
  • Hand-cut edge character
  • Sealing is optional but can aid stain protection

Outdoor porcelain

Best for a controlled appearance and simpler routine care.

  • More consistent colour and dimensions
  • Low water absorption and frost resistance
  • Usually does not need sealing
  • Rectified edges for cleaner joint lines

FAQ

Will every slab look exactly the same?

Porcelain is manufactured for a consistent finish, but colour and surface detail can still vary slightly between production batches. Order enough material for the complete project.

How much extra should I order?

The calculator includes 10% wastage by default. Confirm the final amount with your installer for complex layouts.
