Installing a shower door can help transform your bathroom by giving it a sleek, modern look. With some basic DIY skills and the right tools, installing a shower door is a project you can tackle yourself. Here is a comprehensive guide on how to install a shower door properly.

Choose the Right Shower Door for Your Space

When selecting a shower door, consider the size and layout of your shower area to ensure proper fit. Key factors to evaluate include:

Shower Type

  • Neo angle showers have angled walls and require specialized doors.
  • Corner showers need two doors that meet in the corner.
  • Rectangular showers can use single, biparting, or frameless doors.

Opening Style

  • Hinged doors swing out but require more clearance.
  • Sliding doors conserve space but need parallel walls.
  • Biparting doors have two panels that slide apart.

Glass Type

  • Clear glass provides an open look.
  • Obscure or frosted glass offers more privacy.
  • Tempered safety glass is required for all shower doors.
  • Laminated glass has an inner plastic layer for added impact resistance.

Door Size

  • Measure the width and height of your shower opening.
  • Add 1/16 to 1/8 inch for clearance.
  • Shower doors come in standard sizes like 22×60 inches.

Other Features

  • Chrome, brass, or black metal finishes.
  • Full length door handles provide better grip.
  • Inline, U-shaped, and L-shaped track options.
  • Curved doors for neo angle showers.

Gather the Necessary Materials

Once you’ve selected the ideal shower door, gather all the materials needed for installation:

  • Shower door unit with guides or tracks
  • Side jambs, header, and curb for framing
  • Shims for leveling
  • Screws for securing tracks and jambs
  • Waterproof silicone caulk
  • Power drill and drill bits
  • Level
  • Hacksaw for adjustments
  • Rubber mallet
  • Phillips screwdriver
  • Silicone sealant gun
  • Glass cleaner and towel

Prepare the Shower Opening

Installing the shower door requires a properly prepared and leveled shower opening:

  • Remove existing shower door if replacing.
  • Clean the shower walls thoroughly.
  • Examine for plumb walls and square corners.
  • Fill any holes or imperfections with spackle.
  • Ensure a level, finished sill or threshold.
  • Confirm stud locations for jamb attachment.

Install the Door Tracks and Curb

The shower door tracks provide a guide for the rollers and create a water barrier:

  • Place the curb track on the threshold and mark holes.
  • Drill pilot holes and fasten curb to the floor with screws.
  • Set the jamb tracks vertically and plumb on each side.
  • Drill pilot holes and screw jambs into studs or use anchors.
  • Check tracks are level and corners are square.
  • Cut header track to fit snugly between jamb tracks.
  • Attach header track screws into ceiling or use L-brackets.

Hang the Shower Door

With tracks mounted, it’s time to hang and adjust the shower door:

  • Slide the rollers into the track’s U-shaped channels.
  • Lift door panel and set bottom rollers on curb track.
  • Position top rollers and ensure panel slides smoothly.
  • Use shims under track if door is unlevel or binding.
  • Adjust rollers and jambs until optimal door clearance is reached.
  • Install second door panel for biparting doors.
  • Test doors open and close properly without rubbing.

Apply Waterproof Caulk

Caulking around the shower door seals out water to prevent leaks:

  • Run a bead of silicone along the interior of tracks.
  • Apply caulk along edges where jambs meet walls.
  • Seal all seams between curb and threshold.
  • Apply generous caulk beads where panels meet walls.
  • Use latex caulk at the exterior perimeter for a finished look.
  • Let caulk cure fully for 24-48 hours before use.

Helpful Installation Tips

Follow these tips for a smooth installation process:

  • Review all manufacturer instructions before starting.
  • Confirm the rough opening size is correct.
  • Have a helper hold panels while adjusting rollers.
  • Let silicone caulk fully cure before using shower.
  • Keep glass panels protected during the install process.
  • Save all door hardware parts like rail end caps and washers.
  • Take time to get the door completely level and rolling smoothly.

With the right tools and preparation, you can have your new shower door installed in a day or weekend. The finished product helps create a warm, inviting shower area to enjoy for years to come.

Frequently Asked Questions

What size shower door do I need?

Measure the width and height of your shower opening, then add about 1/8 inch clearance to both dimensions. Standard shower door sizes are 22×60, 25×60, 30×60, 32×60, and 36×60 inches.

How do I remove an old shower door?

Use a screwdriver to detach the metal jambs, then lift and slide out the door panel. Scrape off old caulk around the perimeter before installing the new door.

What type of drill bit is best for shower doors?

Use a masonry drill bit when drilling into tile or concrete. For drilling into wood or metal studs, a standard drill bit works fine.

Should I install the shower door before or after finishing the walls?

It’s best to install the door after your shower walls are completed and waterproofed. The jambs mount directly to the finished walls.

What should I do if my shower walls are not plumb?

Use shims when mounting the jamb tracks to account for out of plumb walls. Adjust shims gradually until the jamb is oriented perfectly vertical.

How long does caulk take to fully cure?

Silicone caulk usually takes 24-48 hours to fully cure and seal your shower door installation. Avoid getting the caulk joint wet during this time.

Can I install the shower door myself?

With some basic DIY knowledge, the right tools, and patience, installing a shower door is definitely a project a homeowner can tackle. Review instructions fully and watch tutorial videos for guidance.

What do I do if water leaks around my shower door?

Check for gaps in the caulk seals and recaulk as needed. Make sure the tracks and curb are properly sealed too. Adjust or replace the door sweep if it’s not making a good seal with the sill or threshold.
