Maintenance
Regular cleaning and maintenance will help preserve the finish and functionality of your shower system.

Troubleshooting
If you encounter issues with your shower system, refer to the following common problems and solutions. For complex issues, contact a qualified plumber or customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
