How to Fix the Hole in My Bathroom Sub-floor
Bathroom floors succumb to moisture and high traffic. Often, this causes holes in the floor and subfloor, especially if particleboard was used when the floor was first installed. When a hole occurs, repairing it quickly helps prevent further damage that adds to the cost. Removing the damaged floor and replacing it helps ensure your flooring is strong. Repairing a hole in the bathroom floor requires the same steps as repairing a hole in any other subflooring. Does this Spark an idea?

Tips & Warnings
Square-edged plywood is easier to install and costs less than tongue-and-groove plywood.
Exercise caution when lifting the plywood; it is heavy and may cause injury to your back. Also, wear your safety glasses and gloves when working with subflooring.
