Before You Begin

Clear out the bathtub area and clean the tub walls and surfaces around it. If there is a shower curtain rod remove it and patch the holes.

Then identify the parts of the door using the installation instructions supplied by the manufacturer. Read the instructions and lay out the parts and hardware. Set the door panels aside to install after the track assembly. Line the tub floor with a heavy drop cloth to protect the finish, or use the large cardboard packaging that the door came in.

  • Step 1 : Measure and cut the bottom track

    Measure and cut the bottom track

    Use a measuring tape to find the distance from wall to wall along the top edge of the tub. Following the manufacturer's directions, calculate the length of the bottom track allowing for the side rails. Cut the bottom track to length and smooth any rough edges with a file.

  • Step 2 : Position the bottom track

    Center the bottom track on the flattest part of the tub ledge and temporarily fasten the track to the ledge with masking tape. Mark the track with a pencil mark along the front edge.

  • Step 3 : Position the wall jambs

    Measure and cut the bottom track

    Hold a wall jamb down over the end of the bottom track and use a carpenter's level next to the wall jamb to adjust it to be plumb. Make a mark in the hole locations for the wall anchors. Remove the wall jamb and drill the holes with a 3/16-in. bit for the wall anchors.

    To drill into ceramic tile, use a masonry drill bit and insert the anchors in the holes, repeating the drilling in the opposite wall for the other wall jamb.
