Buying Guide
What to consider when choosing a 36 inch interior door slab:
- Door type: Choose hollow-core for light weight and easy handling, or solid wood for durability and a premium feel.
- Finish and paintability: Primed surfaces save time; unfinished or natural wood requires finishing work.
- Panel design: Single-panel vs multi-panel affects style; match with room architecture and trim.
- Mounting method: Ensure compatibility with pocket doors, swinging doors, or sliding hardware kits you plan to use.
- Weight and installation: Lighter slabs simplify hinge alignment and frame mounting; heavier options may need extra hardware.
