Can I cut these tiles to fit around corners?+
Yes, you can carefully cut these tiles using a suitable tile cutter. However, be mindful of the edges and consider using edging strips to conceal any cuts and prevent chipping.

The tiles typically have a thickness of around 3-5mm, but this can vary slightly between manufacturers. Always check the product specifications before purchasing.
Are these tiles suitable for use behind a shower screen?+
While visually appealing, these tiles are not recommended for areas directly exposed to constant moisture like behind a shower screen due to potential water damage and grout issues.
