1. Preparing the Shower Area

 Preparing the Shower Area

The initial step in the process of how to install sliding shower doorstep is preparing the shower area. This involves ensuring the area is clean and dry. Start by removing any old caulk or adhesive from the edges of the shower base or bathtub where the new doors will be installed. It’s important to repair any damage to the surrounding tiles or shower enclosure, as this can affect the stability and alignment of the doors. Use a level to check that the shower base or bathtub is even; an uneven base can cause issues with door installation and function.

After preparing the shower area, the next step in installing a sliding shower doorstep is to install the bottom track. Begin by placing the bottom track on the edge of the shower base or bathtub, aligning it with your earlier measurements. Ensure that the track is centered and level. If necessary, use a hacksaw to trim the track to the correct length, ensuring a snug fit. Once positioned correctly, mark the locations for the drill holes. Remove the track and drill holes at the marked spots, then secure the track in place using screws. It’s crucial to apply a bead of silicone caulk along the underside of the track before installation to prevent water leakage. After securing the track, wipe away any excess caulk and allow it to set as per the manufacturer’s instructions. This creates a watertight seal and lays a firm foundation for the remaining installation steps.

3. Setting Up The Side Jambs

Once the bottom track is securely installed, the next step in installing a sliding shower doorstep is setting up the side jambs. These are the vertical frames that will hold the doors in place. Begin by positioning a side jamb at one end of the bottom track, ensuring it’s perfectly vertical using a level. Mark the drill holes on the wall through the pre-drilled holes in the jamb. Remove the jamb and drill the holes in the marked spots. Use wall anchors if necessary for additional support, especially in tiled walls or other hard surfaces. Once the holes are prepared, line the jamb backup and secure it with screws. Repeat this process on the other side of the shower opening. Ensure both jambs are aligned with each other and perpendicular to the bottom track for smooth door operation.

Lift the top track and position it atop the side jambs. Before securing it, use a level to check that it’s perfectly horizontal. If the top track is not level, the doorstep might not slide properly or may appear uneven. Once it’s aligned, mark the drilling points on the side jambs through the pre-drilled holes in the top track. Then, secure the top track to the side jambs with screws.

If it’s sticking or not aligning correctly, adjust the rollers or glides according to the manufacturer’s instructions. Repeat this process with the second door, ensuring that both doors slide without interference and that the overlap between them is consistent along their entire height.

6. Securing And Sealing

The final step in installing sliding shower doors involves securing and sealing them to ensure stability and water-tightness. Begin by installing any door guides or bumpers that come with the door kit. These components keep the doors aligned and prevent them from swinging outwards. Once the doors are moving correctly and aligned, it’s time to seal the enclosure. Apply a bead of silicone caulk along the inside of the bottom track and the areas where the side jambs meet the shower walls.
