Before you begin, you'll need to gather a few essential tools and take a close look at the existing shower seal strip. This prep work ensures a smooth and efficient replacement process.

  • New Shower Seal Strip: Measure the length of your existing strip to ensure you purchase the correct size. Consider upgrading to a newer model with enhanced waterproofing or mildew resistance.
  • Utility Knife or Scissors: A sharp utility knife is ideal for cutting the new seal strip to the precise length. Scissors can work in a pinch, but a knife provides cleaner cuts.
  • Pliers (Optional): If the old strip is particularly stubborn, pliers can help you grip and remove it.
  • Cleaning Supplies: A cleaner, scrub brush, and cloth will be necessary to clean the shower door frame after removing the old strip. Consider a mildew-specific cleaner.
  • Measuring Tape: Always double-check measurements.
  • Gloves A good pair of rubber gloves to protect your hands.

Carefully examine the existing shower seal strip. Notice how it's attached to the door frame. This will give you clues about the best way to remove it. Also, check for any signs of damage to the shower door or frame that might need addressing before installing the new seal.

This step requires a bit of patience and finesse. The goal is to remove the old shower seal strip without damaging the shower door or frame.

  1. Locate the Seam: Identify where the old strip is attached to the door. It may be glued, clipped, or simply pressed into place.
  2. Start Prying (Gently!): Use your fingers or a flathead screwdriver to gently pry the strip away from the door frame. Start at one end and work your way along. Don't force it!
  3. Use Pliers (If Necessary): If the strip is stuck fast, use pliers to grip it firmly and pull it away. Be careful not to scratch the door frame.
  4. Remove Residue: Once the strip is removed, clean any remaining adhesive or debris from the door frame. A scraper or putty knife can be helpful for this task. Rubbing alcohol or a specialized adhesive remover can tackle stubborn residue.
  5. Inspect for Damage: Check underneath the old seal strip for any water damage. Mold an mildew can grow here, so make sure you clean and treat these spots before reinstalling the new shower seal strip.

A clean and dry surface is essential for proper adhesion of the new shower seal strip. This step prevents mold and mildew growth beneath the new seal.

  1. Clean the Door Frame: Thoroughly clean the area where the new strip will be attached. Use a bathroom cleaner to remove any dirt, grime, or mildew.
  2. Scrub Stubborn Spots: For stubborn mildew stains, use a scrub brush and a mildew-specific cleaner.
  3. Rinse Thoroughly: Rinse the area thoroughly with clean water to remove any traces of cleaner.
  4. Dry Completely: This is crucial! Use a clean cloth to dry the area completely. You can also use a hairdryer on a low setting to ensure the surface is bone dry.
  5. Consider a Mildew Inhibitor: If you've had problems with mildew growth in the past, consider applying a mildew inhibitor to the area before attaching the new shower seal strip.

Accurate measurements are key to a perfect fit. Take your time with this step and double-check your measurements.

  1. Measure the Opening: Measure the length of the area where the new shower seal strip will be attached.
  2. Add a Little Extra: Add a small amount (about ¼ inch) to your measurement. It's better to have a little extra than to be short. You can always trim it down.
  3. Cut the Strip: Use a sharp utility knife or scissors to cut the new shower seal strip to the correct length. Make a clean, straight cut.
  4. Test Fit: Before applying the adhesive, put the shower seal strip on and make sure the measurements are correct, and that it lines up well for the bottom of the shower door.

This is the final step! Carefully follow these instructions to ensure a secure and watertight seal.

  1. Peel and Stick (If Applicable): Some shower seal strips come with an adhesive backing. If yours does, peel off the protective paper to expose the adhesive.
  2. Apply Adhesive (If Necessary): If your strip doesn't have an adhesive backing, apply a thin bead of waterproof sealant to the back of the strip. Make sure the sealant is compatible with the materials of your shower door and frame.
  3. Position the Strip: Carefully position the shower seal strip in place, aligning it with the edge of the door frame.
  4. Press Firmly: Press the strip firmly against the door frame, ensuring it adheres securely.
  5. Trim Excess (If Necessary): If you have any excess strip at the ends, trim it off with a utility knife or scissors.
  6. Apply Additional Sealant (Optional): For extra protection, you can apply a thin bead of sealant along the edges of the strip where it meets the door frame.
  7. Allow to Cure: Follow the manufacturers specifications for how long to let the adhesives cure before you get the shower seal strip wet.
