For B2B buyers, material selection is the most critical factor for longevity. Prioritize Solid Wood (Oak or Rubberwood) for high-end markets, or High-Density Plywood with a waterproof veneer for a balance of cost and durability. Avoid low-grade MDF, as it tends to swell. Ensure the countertop is made of Sintered Stone, Quartz, or Grade A Ceramic, which offer superior resistance to scratches and staining. The hardware, including drawer slides and hinges, must be 304 Stainless Steel with soft-close mechanisms to prevent slamming and rust.
