How do I install a bathroom vanity?

Installing a bathroom vanity requires careful attention to plumbing connections, proper support, and waterproofing to prevent costly water damage. While homeowners can handle basic vanity swaps with similar plumbing configurations, most installations benefit from professional expertise to ensure everything is properly sealed and code-compliant.

Preparation is critical before starting any vanity installation. Turn off water supply valves and disconnect existing plumbing lines carefully - old shutoff valves often fail when disturbed and may need replacement. Remove the old vanity by unscrewing it from wall studs and carefully lifting it out. Check that your new vanity will fit properly and that plumbing lines align with the new configuration.

Proper wall support ensures your vanity won't sag or pull away over time. Locate wall studs using a stud finder and mark their positions. Most vanities need to be secured into at least two studs for adequate support. If studs don't align with your vanity's mounting points, install a horizontal mounting board between studs first. For heavier stone countertops, additional blocking may be required.

Plumbing connections are where many DIY installations run into trouble. The supply lines and drain assembly must align perfectly with your new vanity's plumbing layout. If modifications are needed - like moving supply valves or adjusting drain height - this requires a licensed plumber in Ottawa. Even minor misalignments can cause leaks that lead to expensive water damage behind walls.

In Ottawa's market, basic vanity installation typically runs $400-800 for professional installation, while custom work with plumbing modifications ranges $800-2,000. Given that water damage from improper installation can cost thousands to repair, many homeowners find professional installation worthwhile for peace of mind.
