How to Install a Vertical Shower Door Seal Strip? (Step-by-Step)

Step 1: Replace the old Seal Strip

Step 2: Measure the Shower Door 

Use a measuring tape to measure your shower door’s height and width accurately. These measurements will determine the length of the seal strip needed. Measure both sides of the door for a precise fit.

Step 3: Clean the Shower Door and Frame 

Before installing the seal strip, clean the surface of the shower door and frame using rubbing alcohol and a cloth or sponge. Make sure to clean both the inside and outside surfaces thoroughly.

Step 4: Cut the Seal Strip to Size

Use a sharp utility knife to cut the seal strip to the appropriate length based on your measurements. Cut slightly longer than needed, as you can trim off any excess later.

Step 5: Apply Adhesive or Sealant

Apply a thin layer of adhesive or sealant to the back of the strip, following the manufacturer’s instructions. Avoid applying too much to prevent a messy installation.

Step 6: Position the Seal Strip

Align the seal strip along the edge of the shower door, starting from the top and pressing firmly as you work your way down. Make sure it’s correctly aligned and firmly in position.

Step 7: Trim any Excess

Use a utility knife to trim off any excess length of the seal strip at a slight angle for a clean finish. Be sure to avoid causing any damage to the door or its frame during the process.

Step 8: Allow the Seal Strip to Set

Depending on the adhesive or sealant used, allow sufficient time for it to set according to the manufacturer’s instructions. Avoid using the shower for at least 24 hours to ensure a proper seal.

Congratulations on successfully installing your vertical shower door seal strip! Now, let’s discuss some common mistakes to avoid during the installation process.

Tips for Maintaining and Caring for the Seal Strip

  • Regular cleaning: Clean the seal strip regularly with mild soap and warm water to avoid damage.
  • Inspect for damage: Periodically check for wear or damage and replace the strip if issues are noticed.
  • Keep it dry: Wipe the seal strip with a dry cloth after each use to prevent mold and mildew growth.
  • Avoid excessive force: Be gentle when opening and closing the shower door to prevent premature damage to the seal strip.

Alternative Options for Sealing Shower Doors

While vertical shower door seal strips are a popular choice for sealing shower doors, there are alternative options available depending on your specific needs and preferences. Here are a few alternatives:

  1. Bottom door sweep: Attaches to the bottom of the shower door to prevent water leakage and creates a seal with the shower floor.
  2. Magnetic shower door seal: This uses magnets to create a tight seal between the door and the frame, especially effective for frameless shower doors.
  3. Drip rail: Installed at the bottom of the shower door to direct water back into the shower area, preventing water from escaping onto the bathroom floor. 

When choosing an alternative option for sealing your shower door, consider factors such as the type of door, water pressure, and your personal preferences. Consult with a professional or seek advice from a reputable supplier to determine the best option for your specific needs.
