Preparing Your Bathroom for a New Vanity: A Quick Checklist

A bathroom vanity is more than just a functional feature—it’s a major part of your bathroom’s style, storage, and everyday convenience. Whether you're upgrading an outdated fixture or completing a full bathroom renovation, installing a new vanity is an exciting step. But before the tools come out and the installation begins, a little preparation can go a long way.
At Handyman Service St. John's, we help homeowners across St. John’s, Newfoundland, complete smooth and stress-free vanity installations. Here’s a quick checklist to get your space ready and avoid any last-minute surprises.
✅ 1. Measure Twice—Buy Once
Before purchasing a new vanity, measure your space carefully. Take note of:
- Wall-to-wall width where the vanity will sit
- Floor depth (especially in tight bathrooms)
- Existing plumbing locations
- Mirror and light fixture placement
Make sure the vanity you choose fits comfortably without crowding toilets, doors, or showers. If you're upgrading to a larger vanity, double-check that it won’t block outlets or limit accessibility.
✅ 2. Turn Off Water Supply
This is a must. Locate your sink’s shut-off valves (usually under the existing vanity) and turn off the water before any removal begins. Test the faucet to ensure the water is completely off. If you’re not sure where the main shut-off is—or if your valves are stuck—it’s a good idea to let a pro handle it.
✅ 3. Clear the Area
Remove all items from the vanity cabinet, countertop, and surrounding areas. Move bath mats, towels, bins, and anything hanging near the vanity so your handyman has plenty of space to work safely and efficiently.
Tip: Lay down a protective sheet or towel to protect your floor from dust or small debris during removal.
✅ 4. Disconnect Plumbing
Removing the old vanity requires disconnecting:
- Supply lines (hot and cold)
- The P-trap (drainpipe under the sink)
- Possibly your faucet, if it’s being reused
This step can be messy, so it’s best left to a professional unless you're confident with plumbing basics.
✅ 5. Assess the Wall Condition
After removing the old vanity, check the wall for:
- Mold or mildew
- Water damage
- Loose drywall or old mounting hardware
This is your chance to repair any hidden issues before installing the new unit. In damp climates like St. John’s, keeping walls dry and sealed is essential for long-term durability.
✅ 6. Check for Level Floors and Studs
A new vanity needs a level surface to sit properly and be secured to the wall. If your bathroom floor has shifted or your walls are uneven, your handyman may need to make minor adjustments. Finding the studs behind the drywall ensures the vanity can be anchored safely and securely.
✅ 7. Plan for Vanity Height and Sink Type
Modern vanities come in different heights and sink styles—vessel, undermount, integrated, or wall-mounted. Be sure your mirror, backsplash, and lighting align with the type you’ve chosen. A vessel sink, for example, will sit higher and may require lower lighting placement.
