Measurement system

One bathroom vanity in the same location

Estimate installing or replacing one bathroom vanity in the same location only. This does not include moving plumbing, electrical work, wall repair, floor repair, tile work, custom countertop fabrication, major drain repair, mold remediation, or professional labor.

This assumes the vanity fits the existing space and uses the existing water supply and drain location.

Project planning note

Review the selected options, site condition, material assumptions, and tool needs before buying supplies. This calculator is meant for rough DIY planning, not a professional quote.

Leak-check/cure note

After hookup, run hot and cold water, fill and drain the sink, and check supply valves, faucet connections, drain fittings, trap joints, and cabinet floor. Recheck after 30 to 60 minutes. Most bathroom caulk needs several hours to skin over and about 24 hours before regular moisture exposure.

Recommended materials/tools

  • Standard vanity allowance with vanity with integrated top
  • Bathroom faucet allowance included
  • New drain assembly and plumber putty or gasket supplies
  • New hot and cold water supply lines
  • Bathroom caulk for vanity top and wall edges
  • Shims, anchors, screws, cleanup supplies, rags, bucket, and small install supplies
  • Basic plumbing/install tool allowance included

Basic DIY checklist

  • Measure vanity width, depth, plumbing locations, and door/drawer clearances before buying.
  • Shut off water, disconnect supply and drain lines, cut old caulk, and remove the old vanity carefully.
  • Dry-fit the vanity, shim as needed, and anchor it securely to wall framing when possible.
  • Set or confirm the vanity top is level before final plumbing hookup.
  • Install or reconnect faucet, drain assembly, trap, and supply lines.
  • Run water, check every connection, then caulk edges after leak checks.

When to call a pro

  • Call a pro if the drain or supply lines do not line up without forcing parts.
  • Call a pro for moving plumbing, electrical work, tile work, custom countertop fabrication, major drain repair, mold remediation, or professional-grade finish work.

This is a rough DIY planning estimate for installing or replacing one bathroom vanity in the same location only. It does not include moving plumbing, electrical work, wall repair, floor repair, tile work, custom countertop fabrication, major drain repair, mold remediation, or professional labor.
