Cooktop openings leave narrow strips of countertop that can be vulnerable to cracking. Heat may affect some seam adhesives and resin-based materials. A seam should not create unsupported corners or interfere with appliance clips. The final location depends on slab size, cabinet rails, cooktop dimensions, and access for installation.

Key considerations

  • heat resistance
  • seam durability
  • structural stability
  • supported opening
  • appliance clearance
  • planned slab layout
