How to Install a Frameless Shower Door
Updated February 25, 2026
Mount a frameless glass shower door on tile or stone walls -- drilling, anchoring, hinge installation, and getting a watertight seal without a frame.
Overview
Frameless shower doors use thick tempered glass (3/8 to 1/2 inch) mounted directly to the wall and curb with hinges and clamps -- no metal frame around the glass. The result is a clean, modern look that makes the shower feel more open. The installation is more demanding than a framed door because the glass is heavy (60-100 lbs per panel), the hinges must be perfectly positioned (glass cannot be adjusted after drilling), and the wall anchors must hold in tile without cracking it. This is a high-reward project that requires patience and precision.
What You'll Need
Safety First
- Tempered glass is heavy -- 3/8-inch glass weighs about 5 lbs per square foot. A standard shower door panel weighs 60-100 lbs. You need two people for handling and installation.
- Drill tile slowly with a carbide or diamond-tipped bit. Pressing too hard cracks the tile. Let the bit do the work at low speed with water as a coolant.
- If the glass shatters during installation (rare with tempered, but possible from a defect or stress point), it breaks into small cubes, not shards. Still, wear safety glasses and closed-toe shoes.
Step-by-Step Instructions
- Measure and Plan
Measure the shower opening width at the top, middle, and bottom. Measure the height from the curb to the point where you want the top of the glass. Walls are rarely perfectly plumb -- check with a level. If the walls are out of plumb by more than 1/4 inch, the door may not seal properly. Order the door from a glass company with your exact measurements, or buy a semi-custom kit (DreamLine, Aston, VIGO) that fits a range of openings. Allow 2-3 weeks for delivery on custom glass.
Tip: Measure three times. Glass cannot be trimmed after manufacturing. An opening that is 1/4 inch too narrow means the door does not fit. Semi-custom kits with adjustable wall channels give you 1-2 inches of adjustment -- more forgiving than full frameless. - Mark and Drill Hinge Locations
Hold the hinge hardware against the wall where the door will mount. Use a level to ensure the hinges are perfectly plumb. Mark the screw holes with a pencil. For tile walls: start with a carbide-tipped bit at low speed to penetrate the tile glaze. Switch to a masonry bit for the substrate behind the tile. Drill to the depth required for the wall anchors (usually 2-2.5 inches). For tile on cement board over studs, use toggle bolts or stud-mounted anchors for maximum hold. Tile over drywall is less ideal -- try to hit studs.
Tip: Place a piece of painter's tape over the drill location before marking. The tape prevents the drill bit from wandering on the smooth tile surface. Drill through the tape at low speed with steady pressure. - Install the Hinges and Wall Channel
Insert wall anchors into the drilled holes. Mount the hinge plates to the wall with stainless steel screws. Verify the hinges are level and plumb one more time before tightening fully. If the door kit includes a wall channel (a U-shaped metal strip that the glass panel slides into), install it now. Apply silicone to the back of the channel before mounting it -- this seals the gap between the channel and the tile.
Tip: Stainless steel hardware is essential in a wet environment. Chrome-plated steel corrodes within 1-2 years in a shower. Stainless or solid brass hardware lasts the life of the door. - Hang the Glass Panel
This is the two-person step. One person holds the glass while the other connects it to the hinges. Lift the glass panel and align the hinge clamps with the hinge plates on the wall. Insert the pins or tighten the clamp screws to secure the glass to the hinges. The glass should swing freely without rubbing the curb or the opposing wall. Adjust the hinge tension if the door swings too fast or does not hold its position.
Tip: Set the glass on small rubber pads or shims on the curb while positioning it. This protects the glass edge from chipping on the tile curb and gives you a moment to align before securing. - Seal and Finish
Apply clear silicone caulk along every joint where glass meets wall, glass meets curb, and the wall channel meets tile. Use a thin, consistent bead and smooth with a wet finger. Install the door sweep (a flexible rubber or vinyl strip) on the bottom edge of the door where it meets the curb. This deflects water back into the shower when the door is closed. Install the handle hardware with the supplied hardware. Let the silicone cure 24 hours before using the shower.
Tip: Clear silicone is the standard for shower doors -- it stays invisible on glass and chrome. Do not use latex caulk -- it yellows in wet environments and develops mold faster than silicone.
Pro Tips
- Semi-frameless doors ($200-$600) have a frame on the top and bottom but not on the sides. They are easier to install than full frameless (more adjustability) and look nearly as clean. Good compromise between frameless aesthetics and framed ease of installation.
- DreamLine, VIGO, and Aston are the three most popular semi-custom frameless door brands. All ship with hardware, installation templates, and video guides. $300-$1,000 depending on size and glass thickness.
- A professional glass installer charges $200-$500 for labor on a single frameless door panel. For a full enclosure (two or three panels), labor runs $400-$1,000. If you are not comfortable drilling into tile or handling 80+ lbs of glass, the professional route is money well spent.
- Treat the glass with a hydrophobic coating (Rain-X for shower glass, $8-$12) after installation. The coating repels water and prevents hard water spots and soap scum from bonding to the glass. Reapply every 3-6 months.
- The bottom seal (sweep) is the most common wear item. It compresses and hardens over time. Replacement sweeps cost $10-$20 and snap or slide into the channel on the bottom of the glass. Replace every 2-3 years.
When to Call a Pro
Call a glass installer if your shower opening is non-standard and requires custom-cut glass, if the walls are significantly out of plumb (more than 1/4 inch -- the glass will not seal without custom shimming), if you need to drill into stone tile (marble, travertine) which cracks easily, or if the door is a full enclosure with multiple panels and a fixed panel that requires structural attachment.
