Instructions
Confirm Opening Size
Measure the opening width at the top, middle, and bottom — tile surfaces are rarely perfectly parallel. Use the smallest measurement to select your door. Most shower doors accommodate a range (e.g., 56"–60" adjustable).
Identify Door Type
Confirm whether you have a sliding bypass door, pivot door, hinged frameless door, or neo-angle door. Installation steps vary by type — always read the manufacturer's instructions specific to your door model before beginning.
Install Bottom Track
Apply a bead of clear silicone caulk to the underside of the bottom track. Set the track on the shower base threshold, centered in the opening. Use a level to confirm it is straight. Do not drill into the base — silicone holds it.
Mark & Install Side Jambs/Walls
Hold each side jamb plumb against the tile wall and mark screw hole locations. Use a tile or masonry bit to drill into tile carefully at low speed. Insert plastic anchors and screw the jambs into place — plumb in both directions.
Install Top Track or Header
Connect the top track between the two side jambs. Check that the assembly is square and that the top track is level. Adjust jamb heights if needed before tightening all fasteners.
Hang the Glass Panels
For sliding doors: set the stationary panel first into the frame or track, then hang the sliding panel on the rollers. For hinged doors: attach hinges to the glass panel first (if not pre-installed), then mount to the wall jamb at correct height.
Adjust & Align
Open and close the door several times. It should swing or slide smoothly without dragging on the track or floor. Adjust roller height on sliding doors. Adjust hinge screws on pivot doors to correct any lean.
Install Towel Bar & Handle
Attach the towel bar and/or door handle per the manufacturer's instructions. Most attach with set screws into pre-drilled holes in the glass or door frame. Do not over-tighten against glass.
Apply Silicone to All Joints
Apply a neat bead of clear 100% silicone caulk along the inside of both side jambs where they contact the tile wall, and along the inside of the bottom track. Do NOT caulk the outside of the bottom track — water needs to drain back into the shower.
Allow Cure & Test
Let silicone cure 24 hours before using. Then run the shower and check for leaks around the jambs and door sweep. The sweep along the bottom of the door should contact the base enough to direct water inward.
