Shaker vs. 6-Panel vs. Flush: Which Interior Door to Spec
By WholesaleDoorHub Team · May 2026
Direct answer: Wholesale wooden interior doors cost $85–$580 per unit. The key procurement decision is core construction (hollow vs. solid) and species (pine, oak, MDF). For high-volume residential, hollow core MDF is the standard; for premium projects, solid wood stile-and-rail is the specification.
