Read the full guide before starting. Skipping steps can cause rework, misaligned holes, or damage to the product and surrounding surfaces. These instructions are not all-inclusive. We strongly recommend a professional installer if you have any doubts about the process.
Tempered glass handling
Tempered glass is highly durable in normal use, but the corners and edges are the most vulnerable and must be handled carefully during storage, transport, installation, and daily use.
- Avoid impacts, excessive force, and contact with hard surfaces, including screw heads and metal parts.
- Never set glass directly on a hard surface. Always rest edges and corners on cardboard.
- Keep corner protectors on until they need to come off.
- Damage from impact or improper handling may not be visible right away and can cause breakage hours or even days later.
Before installation
- Check all cartons for shipping damage. Report damage, defects, or missing components to Customer Service within 5 business days of delivery.
- Verify compliance with local building and plumbing codes.
- The door is reversible for left- or right-side access. The printed guide shows a left-side installation. Before starting, confirm your layout and identify the fixed glass panel and the door glass panel.
- Confirm the hardware layout and position before each step.
- For updated drawings and guides, see the shower door model webpage listed on the product label.
Required for installation (not included)
Leveling tools, measuring tape, utility knife, plastic putty knife, 100% bath silicone, drill with adjustable torque, and 7/32" and 5/16" drill bits.

Step 1: Shower space preparation
- Make sure the shower kit installation is complete and all adhesives are fully cured.
- Clean the area of debris.
- Place a large piece of cardboard from the packaging on the shower base for protection.
Step 2: Bottom rail
- Dry-fit the edge clips (#6 and #20) 1/8" in from the shower base edge. Mark their holes with a pencil and drill pilot holes in the base with a 7/32" bit.
- Dry-fit the bottom rail (#21) with the edge clips. Trim the rail with an angle grinder and cutting wheel if needed.
- Remove the film from the double-sided tape and attach the rail to the base. Insert the anchors (#17) and secure the edge clips with screws (#18). Use low drill torque to avoid damaging the base.
Step 3: Fixed-side U-channel
Dry-fit the U-channel (#13) on the fixed panel side, flush against the edge clip, and check level. Mark and drill pilot holes in the wall with a 7/32" bit. Apply a thin bead of clear 100% silicone to the back of the U-channel, insert the anchors (#17), and fasten with screws (#18).
Step 4: Top guide assembly
Slide the center guide (#8) onto the top guide (#7). Assemble the mounting clip parts (#10 and #12) on both ends of the top guide and loosely tighten the set screws (#9).
Step 5: Top guide installation
- Dry-fit the fixed glass panel (#15) into the U-channel and set the top guide assembly on top. Trim the top guide with an angle grinder if it is too long.
- Make sure the top guide is level and parallel to the fixed glass. Trace the outline of both mounting clips (#12), then disassemble the top guide and carefully remove the fixed glass.
- Align each mounting clip and cam with its outline. Mark the holes on both walls, drill pilot holes with a 5/16" bit, insert the anchors (#11), and fasten the cams with screws (#9). The mounting clips go on the inside of the shower.
- Set the top guide and center guide onto the mounting clips and tighten the set screws.
Step 6: Fixed panel
- Carefully place the fixed glass panel into the U-channel. From inside the shower, slide the U-channel gasket (#14) along the interior side of the profile using a plastic putty knife.
- With the fixed panel in its final position, attach it to the bottom rail from inside the shower using the bottom hardware clip (#19).
Step 7: Door panel
- Attach the two door wheels (#5) to the glass door panel (#3). Do not reinstall the wheel cover plates yet.
- Carefully lift the door panel onto the bottom rail. Slide the center guide (#8) to secure both glass panels and firmly tighten its set screws.
Step 8: Door alignment
If the wall is not perfectly vertical, adjust the door to close gaps of up to 1/4". Use the included hex key to turn the screw on the side of each wheel, which raises or lowers it to align the door edge with the wall. Once aligned, install the wheel cover plates.
Step 9: Gaskets and handle
- Slide the door gasket (#2) onto the edge of the door, making sure it clears the height of the bottom rail edge clip.
- Attach the magnetic gasket (#1), aligned vertically with the magnet. Remove the film from its double-sided tape and slowly close the door so the magnetic strip sticks to the wall.
- Slide the two center seam gaskets (#16) onto the edges of the glass panels.
- Attach the handle (#4) to the door panel.
Step 10: Sealing
From inside the shower, apply clear 100% bath silicone along the bottom and side edges of the door. Use painter's tape for a clean finish. Let the silicone cure fully per the manufacturer's instructions before using the shower.
