how to install a drain pan for washer

Installing a drain pan for a washer is a practical way to protect your floors from potential water leaks and spills. Here’s a step-by-step guide on how to install a drain pan for a washer:

Materials You’ll Need:

  • Washer drain pan
  • Level
  • Tape measure
  • Pencil or marker
  • Screwdriver or drill
  • Screws or anchors (appropriate for your floor type)
  • Sealant or caulk (optional)


  1. Select the Location:
    • Choose a suitable location for the washer drain pan. It should be placed directly under the washer to catch any water leaks or spills. Ensure that the area is level.
  2. Measure and Mark:
    • Measure the dimensions of the washer’s base or feet to determine the size of drain pan you’ll need. Mark the floor with a pencil or marker to indicate where the drain pan will be placed.
  3. Check for Level:
    • Use a level to ensure that the marked area is level. If it’s not level, you may need to adjust the washer’s feet or use shims to level it.
  4. Place the Drain Pan:
    • Set the washer drain pan in the marked location. Ensure that it is centered under the washer and aligned with the washer’s feet.
  5. Secure the Drain Pan:
    • If your washer drain pan has pre-drilled holes, use them as a guide to mark the positions where you’ll secure it to the floor. If there are no pre-drilled holes, mark the corners of the drain pan.
  6. Drill Holes (if needed):
    • Depending on your floor type (wood, concrete, tile, etc.), use an appropriate drill bit and drill holes at the marked positions. If you’re installing into concrete, you may need anchors for added stability.
  7. Secure the Drain Pan:
    • Use screws or anchors that are appropriate for your floor type to secure the drain pan to the floor. Make sure the drain pan is held securely in place.
  8. Check for Level Again:
    • Recheck the drain pan’s level after securing it to ensure it hasn’t shifted during installation.
  9. Install the Washer:
    • Carefully place the washer on top of the drain pan, ensuring that its feet are resting securely within the confines of the drain pan.
  10. Connect the Drain Hose:
    • If your washer has a drain hose, ensure that it is properly connected to the drain plumbing or an appropriate drain outlet. This will ensure that any water drained by the washer is directed away.
  11. Optional: Seal Edges (if desired):
    • To prevent any water from seeping under the drain pan, you can apply a bead of sealant or caulk along the edges where the drain pan meets the floor.
  12. Test for Leaks:
    • Run a test load in your washer to ensure there are no leaks. Check for any water that may escape the washer and collect in the drain pan.

Installing a drain pan for your washer is a relatively simple and effective way to prevent potential water damage to your floors. It’s especially important if your laundry area is located on an upper floor or over finished living spaces. Proper installation ensures that any water leaks or spills are contained and can be addressed promptly.
