8. Troubleshooting
If you encounter issues with your vanity, refer to the following common problems and solutions:
- Plumbing Clearance Issues: The space for plumbing under the sink can be tight. Ensure your existing plumbing is configured to fit within the cabinet dimensions (15.75"L x 15.75"W x 33.46"H). Adjustments to existing pipes may be necessary.

- Missing Parts: If any parts are missing upon delivery, contact customer service immediately. Note that the vanity and sink are shipped in separate packages and may arrive on different dates.
