Installing a shower door is an excellent way to upgrade your bathroom. A glass shower enclosure gives your bathroom a clean, modern look while preventing water from splashing outside the shower area. Installing a shower door is a manageable DIY project if you have basic carpentry skills and tools.
This comprehensive guide will walk you through the entire How to Install a Shower Door process, from planning and preparation to the installation steps. We’ll cover how to measure for shower doors, types of shower doors, required materials and tools, safety tips, and step-by-step instructions for a successful DIY shower door installation. Let’s get started!
Planning Your Shower Door Installation
The first step when learning How to Install a Shower Door is proper planning and preparation. Here are some key things to consider:
Choose the Right Shower Door Type
There are several shower door types to choose from:
- Frameless shower doors – These have a sleek, elegant look as they lack a metal frame. They consist of glass panels connected by hinges and require careful measurement.
- Semi-frameless shower doors – These have a metal frame on one or two sides but are frameless on the other sides. They offer more flexibility for off-kilter installations.
- Framed shower doors – Full metal framing goes around all sides. This style is the easiest to install but looks less modern.
Consider your bathroom layout, aesthetic tastes, and budget when selecting a shower door type. Frameless doors have a contemporary style, while framed doors offer classic elegance. Semi-frameless strike a balance between the two looks.
Measure Carefully for Accurate Sizing
Grab a tape measure and carefully measure your shower opening before ordering a shower door. Note the width at the top, middle, and bottom of the opening since walls are rarely perfectly plumb. Measure the height on the left, middle, and right sides as well.
Provide the manufacturer or dealer with the smallest measurement for both opening width and height. This will ensure your new shower door will fit the opening properly.
Choose the Right Glass and Hardware
Glass thickness for shower doors ranges from 3/16 inch to 1/4 inch thick. 3/16 inch glass is suitable for most residential uses. For frameless doors, select 1/4 inch thick glass, which is stronger.
Popular hardware finishes include chrome, brushed nickel, oil-rubbed bronze, and matte black. Choose a finish that matches your bathroom fixtures. For a contemporary vibe, matte black or brushed nickel pairs well with frameless doors.
Order the Correct Door Dimensions
Order your shower door to fit the precise measurements of your shower opening. Some additional considerations when ordering:
- Swing direction and clearance
- Type of door opening: sliding or hinged
- Number of doors/panels
- Handle style and placement
Consult the manufacturer’s sizing guides to order the proper dimensions. Allow for a small gap around the perimeter for out-of-plumb openings.
Prepare the Shower Opening
Remove any existing shower track doors or curtains and thoroughly clean the shower area. Remove protruding tiles, caulk, or debris. Ensure the sill (or threshold) is level and solid beneath the door.
Check for plumb walls and 90° angles at shower corners. Shim uneven spots with plastic or composite shims to create a level surface for shower door installation.

How to Install a Shower Door Step-by-Step
Now let’s go through the full shower door installation process from start to finish:
Step 1: Install Side Jambs
The side jambs provide fixed panels for the doors to close against. They usually install directly into the studs flanking the shower opening. Follow these steps:
- Measure and mark stud centers from the outside of the shower. Confirm they align with jamb mounting holes.
- Hold jamb vertically and use a level to plumb it. Mark mounting holes.
- Drill pilot holes if installing into tile. Use a 1/4” masonry bit and hammer drill.
- Fasten jambs using included screws. Use plastic anchors if needed.
- Seal inside perimeter with waterproof silicone caulk. Smooth with fingertip.
Once the plumb jambs are secured on both sides, move onto door installation.
Step 2: Hang the Shower Doors
The sequence for hanging shower doors varies slightly depending on the style:
For Framed and Semi-frameless Doors:
- Attach header bar to top of door opening. Level and plumb it.
- Hang all doors in order by sliding hinge pins into header bar.
- Adjust height so doors are level. Tighten hinge screws.
- Install door handles and any remaining brackets.
For Frameless Doors:
- Install hinges to side of glass panel. Attach with included hardware.
- Lift glass panel and insert hinge pins into pre-drilled jamb holes.
- Adjust height to align panel with fixed side. Tighten hinge screws.
- Install second panel and doors together if it’s a two-door system.
- Add handles and remaining fixtures.
Check that each hanging door is plumb and properly aligned at top and bottom before final tightening.
Step 3. Install Door Seals
Seal up any gaps between the doors and jambs with provided vinyl seals:
- On flat threshold:
- Cut seals to fit vertically in jambs.
- Install U-shaped seal horizontally along threshold, folding up sides.
- For curb threshold:
- Install J-shaped seals over curb dam, folding downward on sides.
- Install straight seals vertically in jambs.
Trim off any excess seal length with utility knife. Avoid stretching the seals. Leave a very small vertical gap between door edge and seal.
Step 4. Caulk Around the Perimeter
Caulking provides the final waterproofing layer. Follow these tips when applying:
- Run a continuous bead of silicone caulk around the interior seam of the shower door jambs and threshold (or curb).
- Use denatured alcohol to smooth the caulk for a clean look.
- Don’t caulk over the vertical door seals. Leave small gaps at the seal joints.
- Allow 24 hours for caulk to fully cure before using shower.
Step 5. Install Door Stops
Door stops prevent the swinging glass doors from opening too forcefully. Mount them as directed:
- Wall-mounted stop moldings attach to the wall with the included hardware.
- Floor-mounted stops are placed in the tile joint or adhered to base of jamb.
- For frameless doors without jambs, use an overhead stop or floor stopper.
Position the stop molding so the door has clearance when opening but contacts the molding before hitting walls or jambs.
Troubleshooting Shower Door Installation Issues
Even with good planning, you may encounter a few issues during shower door installation:
Doors don’t align evenly – Adjust hinge height in incremental turns until aligned. Use shims if needed. Ensure header bar is level.
Doors won’t close properly – Check plumb angle of side jambs. Adjust strike screws inwards if needed so magnets align and seal.
Doors leak – Apply more caulk around problem areas and ensure vertical seals meet tightly.
Glass rattles – Tighten hardware joints. Add rubber bumpers or padding at contact points.
Hard to slide – Adjust rollers and guides. Use silicone spray lubricant. Ensure door tracks are level.
Carefully installed shower doors should last for many years if properly maintained. Contact the manufacturer for any issues under warranty.
Maintaining Your Shower Doors
Follow these tips to keep newly installed shower doors looking beautiful:
- Use a squeegee to wipe water off glass doors after showering. Allowing water to air dry leads to buildup.
- Keep tracks and rollers free of debris, hair, and gunk by cleaning monthly. Use an old toothbrush to scrub.
- Use non-abrasive glass cleaner and lint-free cloth to clean doors as needed. Avoid harsh cleansers.
- Inspect sealant. Re-caulk if cracking or peeling occurs. Mildew indicates re-caulking is needed.
- Check for loose screws, broken parts, and misalignment. Tighten hardware or replace broken parts promptly.
- Lubricate rollers/guides with silicone spray lube every 3-6 months to prevent squeaking.
Proper maintenance keeps shower doors functioning smoothly while looking pristine.
