Buying Guide: Baseboard Molding For Bathrooms
- Moisture resistance: Prioritize PVC or vinyl with waterproof and rot-proof properties to survive humidity and splashes.
- Adhesive vs. nails: Self-adhesive backings offer quick DIY installation; consider surface cleanliness and temperature for best results.
- Flexibility vs. rigidity: Flexible vinyl can fit curved walls and uneven edges; rigid PVC is typically clearer for straight runs.
- Finish and color: Choose white for versatility, gray for a muted tone, or black for a bold accent that complements fixtures.
- Length and joints: Longer rolls reduce seams; plan cuts to minimize visible joints in high-visibility areas.
