Step 1 · Prepare the Workspace

Begin by removing all items from the cabinet under the bathroom sink to create a clear and accessible workspace. Place a medium-sized bucket directly under the U-shaped bend of the P-trap assembly. This bucket is essential for catching the water and debris that will spill out when the trap is removed. For added protection against spills and splashes, lay down a few old towels or rags on the cabinet floor around the bucket.
