Quick answer: Yes, you can install a fixed glass shower panel yourself. The U-channel mounting system is designed for DIY. You need a drill, level, tape measure, screwdriver, and a helper to lift the glass (the panel weighs about 100 pounds). The process takes about 2 hours from start to seal. Wait 24 hours for the silicone to cure before running water. Below is the full 8-step guide with pro tips at every stage, based on 13 years of glass manufacturing and feedback from 600,000+ customers.
What You Need Before You Start
Tools and Materials
- Drill with a masonry bit (for tile walls) or standard bit (for drywall with anchors)
- Level (24 inches or longer)
- Tape measure
- Screwdriver (Phillips head)
- Rubber mallet (for gently tapping glass into channel)
- Suction cup handle (recommended for safely lifting the glass panel)
- Silicone sealant (clear, mildew-resistant)
- Wall anchors (included with the Fab Glass and Mirror panel)
- Pencil for marking
- Helper (strongly recommended for lifting the glass)
The Fab Glass and Mirror Framed Fixed Glass Shower Panel ships with the U-channel, screws, and wall anchors included. The panel itself is 34 inches wide by 74 inches tall, made from 3/8-inch SGCC-certified tempered glass with a matte black aluminum frame. Before starting, confirm you have already measured your opening correctly. If you have not measured yet, review the measuring steps in our complete guide to fixed glass shower panels first.
Safety First
Tempered glass is safe and strong, but it is heavy. The 34 by 74 inch panel weighs approximately 100 pounds. Always lift with two people or use a suction cup handle. Wear closed-toe shoes and work gloves. If the panel cracks or chips during handling, do not install it. Contact our support team immediately.
The 8-Step Installation Guide
1: Prepare the Shower Area
Remove the old shower door, curtain, or any existing hardware from the shower area. Clean the wall surface where the U-channel will mount. If you are installing on tile, make sure the grout lines are clean and dry. If you are installing on drywall, check that the surface is solid and not crumbly. Clear the floor of any rugs or objects that could trip you while carrying the glass.
2: Mark the U-Channel Position on the Wall
Hold the U-channel vertically against the wall where the panel will sit. Position it so the channel opening faces the shower interior. Use your level to confirm the channel is perfectly plumb (vertical). Once level, mark the screw hole positions on the wall through the channel holes using your pencil. Mark at least 4 to 6 screw positions along the 74-inch height.
Pro Tip
If your wall has bullnose tile or decorative trim that sticks out, account for it. The U-channel needs to sit flush against the actual mounting surface. You may need to notch the channel or use shims to create a flat mounting plane.
3: Drill Pilot Holes and Insert Wall Anchors
Remove the U-channel and drill pilot holes at each marked position. For tile walls, use a masonry bit and drill at a slow speed to avoid cracking the tile. Apply gentle, steady pressure. For drywall, use a standard bit sized for your wall anchors. Insert wall anchors into each hole. Tap them gently with a mallet until flush with the surface.
Pro Tip
Put a piece of masking tape on the tile where you will drill. This prevents the masonry bit from wandering on the smooth tile surface and helps prevent cracking.
4: Secure the U-Channel to the Wall
Position the U-channel over the drilled holes. Drive screws through the channel and into the wall anchors. Do not overtighten. Once all screws are in, check the channel with your level one final time. If it is not plumb, loosen the nearest screw, adjust the channel, and retighten. The channel must be perfectly vertical before you insert the glass.
5: Apply Silicone Sealant Inside the Channel
Run a continuous bead of clear, mildew-resistant silicone sealant along the inside groove of the U-channel where the glass will sit. This does two things: it cushions the glass to prevent direct contact with the metal, and it creates a waterproof seal that prevents water from running behind the channel. Apply enough sealant to fill the groove without overflowing.
6: Lift and Insert the Glass Panel
This is the step where you need a helper. With two people, lift the glass panel and carefully guide the edge into the U-channel. Start at the top and let the panel slide down into the channel. The silicone sealant will create slight resistance, which is normal. If the panel does not slide in easily, check that the channel is clear of debris and that the channel opening is wide enough.
Pro Tip
Use a rubber mallet to gently tap the top edge of the panel if it needs help settling into the channel. Tap lightly. Never strike the glass directly with metal tools. If the panel resists, stop and investigate rather than forcing it.
7: Secure the Bottom Channel and Seal All Edges
If your installation includes a bottom U-channel on the curb or floor, secure it the same way as the wall channel: mark, drill, mount, sealant, and insert. Once the panel is fully seated in both channels, run a bead of silicone sealant along every edge where the glass meets the wall, the curb, and the channels. Smooth the sealant with a wet finger or a sealant smoothing tool for a clean finish.
8: Let the Sealant Cure, Then Test
Allow the silicone sealant to cure for 24 hours. Do not run water in the shower during this time. After 24 hours, run the shower for 5 minutes and check every sealed edge for leaks. If you see water escaping, dry the area completely, apply additional sealant, and wait another 24 hours before testing again.
5 Mistakes to Avoid When Installing a Fixed Glass Panel
These are the most common installation errors we see from DIYers. Each one is preventable.
1: Not Checking Wall Plumb Before Mounting
If the wall leans in or out by even 1/4 inch over 74 inches, the panel will sit at an angle. This looks wrong and can cause the glass to bind in the channel. Always check plumb before drilling. Use shims behind the U-channel if the wall is not perfectly vertical.
2: Skipping the Silicone Sealant in the Channel
Some installers skip the sealant inside the channel, thinking the screws hold everything in place. The sealant is not just for waterproofing. It cushions the glass against the metal channel. Without it, the glass can rattle against the aluminum during daily use, which over time can cause chips or cracks. Always apply sealant.
3: Forcing the Glass Into the Channel
If the panel does not slide into the channel smoothly, something is wrong. It could be debris in the channel, a misaligned channel, or a buildup of too much sealant. Forcing the glass with excessive pressure is how panels crack during installation. Stop, investigate, and fix the obstruction before continuing.
4: Drilling Into Tile Too Fast
Tile cracks when you drill too fast or apply too much pressure. Use a masonry bit at low speed. Let the bit do the work. Apply steady but gentle pressure. The hole should take 30 to 60 seconds to drill through standard ceramic tile. Rushing this step costs you a cracked tile and a trip to the hardware store for a replacement.
5: Testing Water Before the Sealant Cures
Silicone needs 24 hours to fully cure. Running water before that washes away the uncured sealant, breaks the waterproof seal, and means you have to remove the old sealant and redo it. Be patient. One day of waiting saves you hours of rework.
How to Keep Your Panel Looking New After Installation
Once your panel is installed, maintenance is simple. Squeegee the glass after every shower to prevent hard water spots. Once a week, wipe the glass and frame with a microfiber cloth and standard glass cleaner. The matte black aluminum frame needs no special treatment and will not rust.

Installing a Fixed Glass Shower Panel: Your Questions Answered
Yes. A framed fixed glass panel with a U-channel mounting system is designed for DIY installation. The U-channel attaches to the wall with screws, and the glass slides into the channel. Most DIYers finish in about 2 hours. The panel weighs roughly 100 pounds, so having a second person to help lift it is strongly recommended for safety.
About 2 hours for a DIYer with basic tools. The actual glass insertion takes 15 to 20 minutes. The rest is spent measuring, marking, drilling, mounting the U-channel, and sealing. After installation, wait 24 hours for the silicone sealant to cure before running water in the shower.
You need a drill with a masonry bit (for tile), a level at least 24 inches long, a tape measure, a screwdriver, a rubber mallet, and ideally a suction cup handle for safely lifting the glass. Silicone sealant and wall anchors are required, and both are included with the Fab Glass and Mirror panel.
A 34 by 74 inch panel made from 3/8 inch tempered glass weighs approximately 100 pounds. It is manageable for two people to lift and position. A single person can do it with a suction cup handle, but a helper is strongly recommended to avoid dropping the glass or cracking it during insertion.
