Buying Guide
What should you check before buying white interior door knobs?
- Door compatibility: Confirm door thickness and backset (35-50 mm is common for interior doors; some options offer 60-70 mm backsets).
- Finish and style: Porcelain versus ceramic, chrome or brass plates, and the level of gloss or matte finish should match your decor.
- Privacy vs. passage: Privacy knobs lock from inside; passage knobs do not. Choose based on room function (bathroom/ bedroom vs. hallways or closets).
- Durability: Zinc alloy rosettes and glazed porcelain contribute to longevity in moisture-prone areas like bathrooms and kitchens.
- Maintenance: Glossy finishes show water spots; matte finishes can hide fingerprints better.
