Welcome to this comprehensive guide on how to install a Delta glass shower door. Upgrading your bathroom shower with a sleek, modern glass door can significantly enhance the overall aesthetic and functionality of your space. In this step-by-step guide, we’ll walk you through the process from start to finish, ensuring you’re armed with the right tools, knowledge, and confidence to achieve a professional-looking result.
Before you begin, ensure you have carefully measured your shower opening to ensure your new Delta glass shower door fits perfectly. Additionally, check the door’s weight and size to guarantee it’s compatible with your existing framing. Once you’ve verified these details, gather your tools, and let’s get started.

Preparation and Tools
The first step in this process is gathering the necessary tools and ensuring your workspace is clean and organized. You’ll need the following:
- Delta glass shower door kit
- Screwdriver or drill
- Tape measure
- Safety glasses
- Silicon caulk
- Caulk gun
- Utility knife
- Safety gloves
Always prioritize safety by wearing appropriate clothing, securing any loose hair, and using safety equipment like glasses and gloves.
Measuring and Aligning
Begin by measuring the width, height, and depth of your shower opening. Unlike traditional shower curtains, glass doors require precise measurements for a snug fit. Your Delta glass shower door kit should come with detailed installation instructions. Follow these closely, as they may include specific adjustments for your specific model.
Once measured, align the door frame and the parti-wall (the wall that separates your shower from the rest of your bathroom) to ensure they’re level and square. You can use a level and a tape measure to achieve this. These steps are crucial to ensure your door is installed correctly and functions smoothly.

Installing the Frame
Begin installing the frame by mounting the header (top piece) to the wall and ceiling using the provided screws or anchors. Ensure it’s level and securely attached. Next, install the side jam (vertical piece) onto the wall on one side of the shower opening, aligning it with the header.
Repeat this process on the other side of the shower opening, ensuring both sides are level and align with the parti-wall. Temporarily place the door panel into the frame to check the fit. Make any necessary adjustments before securing the frame permanently.
Installing the Door Panel
Your Delta glass shower door kit should come with a door panel and roller hardware. Begin by attaching the roller hardware to the top of the door panel. Ensure it’s centered and securely attached.

Next, lift the panel into the frame and align it with the roller hardware. Ensure the door swings freely and smoothly on its rollers. The door should be able to slid back and forth with ease, ensuring a proper fit in the frame.
Hinges and Threshold
Attach the hinges to the door panel, aligning them with the side jam of the frame. Ensure the door swings freely and correctly. You may need to adjust the positioning to achieve this.
Once the door is swinging correctly, install the threshold at the bottom of the frame. Ensure it’s level and fits snugly against the door to prevent water from leaking out of the shower.
Testing and Fine-Tuning
With the door fully installed, test it by opening and closing it repeatedly to ensure it functions smoothly. If the door feels heavy or doesn’t close properly, you may need to adjust the hinges or the threshold.

Finally, apply a bead of silicon caulk around the perimeter of the door frame, sealing any gaps to prevent water from leaking out of the shower. Allow the caulk to dry completely before using your new Delta glass shower door.
Congratulations! You’ve successfully installed your new Delta glass shower door. Enjoy your upgraded shower space.
