How to Reseal a Shower Drain With Silicone

Remove the old drain seal using the craft knife blade. Pass the edge of the blade between the drain flange and the seal to cut them apart, then pull the seal out.

Cut off the tip of the silicone sealer with scissors to create a 45-degree angle opening on the underside of the tube. This will allow you to get to silicone deep into the join of the drain and the shower.

Hold the tip of the sealer right in the drain gap and squeeze out the silicone using consistent pressure. This will maintain a regular silicone bead.

Move the tube around the drain until you complete the bead in a solid circle. Make sure there are no gaps or breaks in the bead.

Wet your finger and run it along the silicone to smooth it out. Press the seal down and spread it between the drain and the shower floor.
