Replacing a framed sliding shower door is an approachable DIY project of about 2 to 4 hours, with framed kits costing $100 to $400. The work is measuring, cutting the bottom track to your opening, and setting the frame level and plumb, then sealing it watertight. A framed door is DIY-friendly. A heavy frameless glass door is a different animal, demanding precise hardware and often studs or blocking, and is frequently worth having installed professionally. The only tool skill needed is drilling tile cleanly for the jamb anchors.

Step-by-step: swapping a framed sliding door

  1. Remove the old door. Lift the panels out of the top track, unscrew the top track from the jambs, remove the side jamb screws and pry the jambs off, then free the silicone-bedded bottom track with a putty knife.
  2. Clean the opening. Scrape all old silicone and residue off the tub ledge and walls, fill old anchor holes, and let everything dry. A clean surface is essential for the new seal.
  3. Measure and cut the bottom track. Measure the opening width per the manufacturer's instructions (usually the narrowest of top and bottom), and cut the bottom track to length with a hacksaw, deburring the ends.
  4. Set the bottom track. Dry-fit the track centered on the ledge, mark it, then bed it in a bead of silicone and press it down. Do not screw the bottom track; it floats on silicone.
  5. Plumb and mark the jambs. Stand a side jamb over the track end, hold it plumb with a level, and mark the screw holes on the tiled wall.
  6. Drill the tile and anchor the jambs. Tape the marks, drill with a carbide or diamond tile bit at low speed and light pressure, seal the holes with silicone, set anchors, and screw the jambs on plumb. Repeat on the other side.
  7. Fit the top track and panels. Set the top track into the jambs, secure per the instructions, then hang the sliding panels on their rollers into the top track and check they glide freely.
  8. Seal it watertight. Silicone the outside of the bottom track and both jambs, inside and out where the frame meets the walls, but leave the inside of the bottom track and its weep holes open so trapped water drains into the tub. Let it cure before use.

Tools and materials

You need a hacksaw, a drill/driver, a carbide or diamond tile bit, a level, a caulk gun and 100% silicone, wall anchors, painter's tape, and a putty knife. A door swap is often part of a wider shower refresh, so it pairs with the other wet-area jobs in this hub; see our shower resealing guide for the sealing technique, and upgrading the fixtures at the same time with a model from the shower head roundup or a shower filter to cut the scale that clouds new glass rounds out the job.

Straight Answers

Frequently Asked

How do you measure for a replacement sliding shower door?

Measure the width across the top of the tub or shower ledge from wall to wall, and again at the bottom, because walls are rarely perfectly parallel; use the appropriate measurement the manufacturer specifies, usually the narrowest. Most framed sliding doors are sold to fit a range and the bottom track is cut to your exact opening. Also measure the height from the ledge to where the top track will sit to confirm the door height suits your walls. Buy a door whose adjustable range brackets your opening width, and always follow the specific brand's measuring instructions, as they differ.

Can you install a sliding shower door over tile?

Yes, that is the normal case. The side jambs screw into the tiled walls with wall anchors, and the bottom track sits on the tub ledge or shower curb bedded in silicone. Drill the tile for the jamb screws with a carbide or diamond tile bit at low speed and light pressure, tape over the marks so the bit does not skate, and set plastic anchors. Seal each hole and the track with silicone so water cannot get behind the tile. Never hammer-drill the tile face. The key is a level, plumb frame sealed watertight to the surround.

Do you caulk the inside or outside of a shower door track?

Caulk the outside of the bottom track and both side jambs, and leave the inside of the bottom track uncaulked with its weep holes clear. The logic mirrors a toilet: you seal the outside so water cannot escape onto the bathroom floor, but any water that gets inside the track must be able to drain back into the tub through the weep holes rather than being trapped. Sealing the inside of the track traps water and breeds mildew. So: silicone the outside perimeter and the jambs, keep the inside track and its weep holes open.

How do you remove an old framed shower door?

Start at the top. Lift the sliding panels up and out of the top track, then unscrew and remove the top track, which usually just sits in the side jambs. Remove the screws holding the side jambs to the walls and pry them off, then the bottom track, which is bedded in silicone on the tub ledge. Cut the old silicone with a utility knife and work a putty knife under the track to free it. Scrape all the old caulk and residue off the tub ledge and walls, and fill any leftover anchor holes before installing the new door.

Are frameless sliding shower doors harder to install than framed ones?

Yes, meaningfully. Framed sliding doors are forgiving: the frame hides small out-of-level and out-of-plumb conditions and the panels are lighter, making them a solid DIY project. Frameless and semi-frameless doors use heavy glass, precise hardware, and often require drilling into studs or blocking to carry the weight, with far less tolerance for an out-of-square opening. A frameless door that is even slightly off will bind or not seal. If you want frameless glass, especially a heavy bypass or pivot panel, many homeowners have it professionally measured and installed to avoid a costly mistake with the glass.
