Design Trends And Granite Thickness

When it comes to kitchen renovations, granite countertops remain a premium choice. Their thickness not only impacts durability but also influences the overall design and aesthetics.

Current Style Preferences In Granite

The current trend in countertops swings between streamlined slim profiles and substantial, statement-making thicknesses. Traditionally, granite countertops come in two major thicknesses:

  • 2cm (¾ inch) – Often used for bathrooms or as decorative elements.
  • 3cm (1 ¼ inch) – Preferred for kitchens due to its sturdiness.

Today, a sleek 2cm countertop might be paired with a thick edge to combine looks with functionality.

Decorators and builders might layer granite slabs for a visually intriguing edge profile. This technique can accentuate the stone’s natural beauty and add character to the counter.

Innovative edge profiles, such as a mitered edge, allow for the appearance of a much thicker slab without the added weight and cost of a full-thickness slab.
