A flush door is a simple yet durable door style with a smooth surface, commonly used in modern homes and offices. It is made using materials like plywood, MDF, or blockboard, and often finished with laminates, veneers, or paint for a sleek look. Flush doors are available in different thicknesses, usually ranging from 25mm to 40mm, and can be plain, laminated, veneered, or even fire-rated for extra safety. They are termite-resistant, easy to maintain, and long-lasting. Depending on the type and finish, the cost of a flush door starts around ₹2,000–₹5,000 for basic options, ₹6,000–₹12,000 for laminate or veneer finishes, and ₹15,000 or more for premium or fire-rated doors.
