When designing high-quality cabinetry, the cabinet box material is just as important as the door style. Cabinet boxes determine structural strength, moisture resistance, durability, and long-term performance—especially in kitchens, bathrooms, and high-use areas.

At RTI Cabinets, we offer a range of premium cabinet box materials, including melamine and birch plywood, to suit different design styles, budgets, and performance needs. This guide breaks down each option, its pros and cons, and the best application for your project.

Cabinet box materials affect:

  • Strength and load capacity

  • Moisture and humidity resistance

  • Interior appearance
