Buying Guide
- Door Type and Opening: Choose slab doors for straightforward replacement on existing frames, pocket doors for space-saving needs, or barn-style doors for style and wide openings.
- Core Material: Solid-core MDF doors offer better moisture resistance and sound dampening than hollow-core options. Consider a door with a gas-tight or laminated core if moisture is a concern.
- Finish and Paintability: White primer doors provide a ready-to-paint surface. Frosted glass panels add privacy while letting light pass through; ensure your room’s lighting supports the desired effect.
- Hardware Requirements: Some listings arrive without hinges or handles. Plan to buy compatible hardware separately and confirm bore hole placement before purchase.
- Size and Fit: Measure the opening precisely. An 18″ door typically fits a 20″ opening width with 82″ height, but always cross-check with the product’s listed fitment.
