A frameless shower enclosure can dramatically transform the look and feel of any bathroom. Its sleek, modern appearance not only adds elegance but also creates an illusion of more space. Among the various designs available, the 90-degree frameless shower is one of the most popular choices. This type of enclosure features two glass panels that meet at a right angle, typically enclosing a corner space. Installing one can be a manageable DIY project if you are comfortable with tools and precision work. Here’s a comprehensive guide to help you install a 90-degree frameless shower in your bathroom.
Step 1: Preparation and Planning
Before starting the installation, proper planning is essential. First, take accurate measurements of your shower area. Measure both walls where the glass panels will be mounted and determine the height and width of the glass panels and door. Most frameless shower enclosures are custom-made, so precision is key.
Ensure the walls are plumb (vertically straight) and the floor is level. Frameless systems have minimal adjustability, so uneven surfaces can cause issues with fitting and water leakage. If your walls are not plumb, consider hiring a professional or correcting the walls before proceeding.
Step 2: Gather Materials and Tools
To install a frameless 90-degree shower, you’ll need:
Tempered glass panels and door (pre-measured and cut)
Hinges and support brackets
U-channels or glass clamps (if used)
Silicone sealant (clear)
Measuring tape
Level
Power drill with masonry bits
Screwdriver
Masking tape
Shims or wood blocks
Suction cups (for glass handling)
Always wear safety gloves and protective glasses while handling glass or drilling.
Step 3: Install the U-Channels or Brackets
Depending on your chosen design, you’ll either mount U-channels or individual clamps to support the glass.
Mark Placement: Use a level to mark where the channels or clamps will be fixed along the floor and walls.
Drill Holes: Carefully drill holes into the tile or wall material using the appropriate drill bit. Insert anchors where necessary.
Install Channels/Clamps: Secure the U-channels or mounting brackets with screws. Double-check alignment before fully tightening.
Step 4: Set the Fixed Panels
With your support structures in place:
Carefully place the first fixed glass panel into the U-channel or clamps along the wall.
Use a level to ensure it’s perfectly vertical. Adjust with shims if needed.
Temporarily secure with masking tape or suction holders.
Repeat the process for the second fixed panel, aligning it to form a 90-degree angle with the first. Where the two panels meet, you may use a corner clamp or silicone to bond them, depending on the design.
Step 5: Install the Shower Door
Mark Hinge Placement: With the door on a flat surface, mark the hinge positions according to your manufacturer’s instructions.
Attach Hinges: Secure the hinges to the wall or to one of the fixed glass panels, depending on the design. Some doors attach directly to one panel; others to the tiled wall.
Mount the Door: With help, carefully lift and align the door to the hinges. Tighten all fasteners, checking that the door swings smoothly and evenly.
Make adjustments as needed to ensure the door doesn’t rub against the glass panels or the floor.
Step 6: Apply Silicone and Seal
Once everything is aligned, apply a bead of clear silicone sealant along the joints where the glass meets the wall and floor.
Also seal the area where the glass panels meet if not using corner clips.
Avoid sealing the inside of the shower where water should naturally drain; focus on exterior seams to prevent leaks.
Allow the silicone to cure for at least 24 hours before using the shower.
Step 7: Finishing Touches
Clean the glass and hardware with a non-abrasive cleaner.
Check that all hardware is secure and that the door opens and closes without obstruction.
Install any optional components such as towel bars or handles.
Final Thoughts
Installing a 90-degree frameless shower adds a sophisticated, upscale look to your bathroom. While the installation process requires attention to detail and patience, it’s a rewarding project for a confident DIYer. If you’re unsure about any step, especially handling large glass panels, consider hiring a professional to assist with installation. With the right preparation and care, your new frameless shower will offer both style and function for years to come.
