Bathroom
Shower door installation cost
A framed sliding door fitted is about $680 and a frameless panel and door about $1,925 — but the price is the last question here, not the first. Three measurements decide which doors are possible at all: how far the walls lean, how much opening you are actually left to walk through, and whether there is anything behind the tile to hold 74 lb of glass. None of them take longer than a minute, and no showroom will ask you for them.

Measure the opening before you choose the door
Three measurements decide which doors you are allowed to buy, and a shop will ask you for none of them. The width, the floor outside, and how far the walls lean.
Wall to wall at the threshold. Measure at the bottom, the middle and the top — if they differ, use the smallest.
About 72 for a shower and 58 to 60 over a bathtub. To the ceiling is possible and costs the extra glass.
How far the walls lean
This is the measurement that decides everything, and it is the one nobody takes. Hold a level against the wall at each side of the opening and see how far the top sits out from the bottom.
Pick a figure once you have held a level on it. Until then every price below is provisional.
The door
The usual frameless answer on a tub-sized alcove: a fixed panel takes most of the width and a door of 24 to 30 inches hinges off it or off the wall. The fixed panel is normally the larger half of the glass order and nobody expects that.
Glass, hinges and clamps, and nothing to hide behind. It is templated after the tiling is finished because it has no frame to absorb a wall that leans, and the panels are cut to that template and cannot be altered afterwards.
The standard frameless thickness and the sensible one. Stiff enough to hang unframed, and half again the weight of a kit panel.
From the threshold to the first thing in the way — the toilet, the vanity or the opposite wall. A hinged shower door has to open outward, so this is not negotiable.
For a niche return, a bench or a valve that the glass has to clear.
Worth it on hard water. It is a coating with a life of a few years, not a property of the glass.
A frameless panel arrives cut to a template, with the hinge holes already in it. The wall has to come to the glass.

A fixed panel and a hinged door, frameless, fitted
$1,925
30 ft² of glass · 28 in to walk through · heaviest panel 74 lb
28 in of clear opening
Not the width of the glass — the width of the gap you actually step through once one panel is parked in front of the other or a door is hinged out of the way. It is the number that decides whether a shower is pleasant to use, and no product listing gives it to you.
Do this before you order anything
Hold a level against both walls
A ten-dollar level, two minutes. See how far the top of each wall sits out from the bottom. That single number decides which of these doors can be bought at all — framed takes 0.5 in, semi-frameless takes 0.375 in, frameless takes 0.25 in — and a wall that leans more than the door tolerates leaves a tapering gap that no amount of silicone will close.
Until it is measured, every figure on this page is provisional.
74 lb on two hinges, into a wall that is about to be tiled
That is roughly 37 lb at each hinge, screwed through the tile into whatever is behind it. It needs solid blocking, and blocking cannot be added once the tile is on. This is the reason a door that gets fitted last has to be chosen first.
The same opening, four doors
What each one leaves you to walk through, and what each one costs.
| Configuration | Fitted | Clear | On this opening |
|---|---|---|---|
| Sliding, two panels | $1,030 | 28 in | 28 in of clear opening. |
| A single hinged door | — | 58 in | The opening is over the 36 in this can span. |
| A fixed panel and a hinged door · yours | $1,925 | 28 in | 28 in of clear opening. |
| A fixed screen, no door | $975 | 24 in | 24 in of clear opening. |
What the door is made of
- Tempered glass, 30 ft² at 3/8 in
A 30 in door and a 30 in fixed panel. The fixed panel is the larger half of most orders and nobody expects that.$600 - Hardware
Hinges, handle, wall clamps and seals — and a brace bar across the top if the fixed panel is wide enough to want one.$645 - Template and installation
Two visits and two people: a template once the tiling is grouted, then the fit two to three weeks later when the glass comes back.$680
What it costs
National average. A fixed panel and a hinged door, frameless, 3/8 in glass on a 60 × 72 in opening. Not included: the tiling behind it, and any blocking that should have gone in before that tiling.
A door is the last thing fitted and one of the first things that has to be decided — the blocking behind the tile and the squareness of the opening are both settled long before anybody measures for glass. If the shower itself is still being built, that is the page to start from, and the tile that goes around this opening is a calculation of its own.
Worth knowing
- Nobody has measured the plumb of this opening yet, and it is the measurement that decides which door you are allowed to buy. Hold a level against each wall of the opening and see how far the top is from the bottom. Frameless tolerates about 0.25 in; beyond that the gap opens into a wedge that no amount of silicone closes. It takes a minute and it is the difference between ordering the right door and ordering an expensive one that does not fit.
- That door leaf is 74 lb of glass and it hangs on two hinges screwed into the wall — about 37 lb on each. It needs solid blocking behind the tile, and blocking cannot be added afterwards without taking the tile off. This is why the door has to be decided before the tiling even though it is fitted last.
- Frameless glass is templated after the tiling is finished and grouted, not before, because there is no frame to absorb a wall that leans. Expect two to three weeks between a shower you can use and one you can close — and the panels are cut to that template and tempered, so nothing about them can be altered afterwards. A chipped edge on delivery is a new panel.
On this page — 5 sections
The measurement that decides which doors you may buy
The short version
- How far the walls lean decides the system. Framed takes 0.5 in, frameless 0.25.
- A sliding door gives back half the opening — and under about 48 in it misses the code minimum.
- 74 lb on two hinges needs blocking behind the tile, and blocking cannot be added afterwards.
- $680 framed, $1,925 frameless on the same 60 in opening.
Everybody starts this job in a showroom. It is the wrong end. Before any of those doors is a real option, three numbers have to exist, and a shop will ask you for none of them.
The first is the one nobody takes: how far the walls lean. Hold a level against each side of the opening and see how far the top sits out from the bottom. In an older house a quarter of an inch is unremarkable and half an inch is common.
That number is not a curiosity. It is the specification. A framed door has aluminium up both walls, and the frame is scribed to whatever the wall is doing — that is what a frame is for. A frameless door has nothing. It is a rectangle of tempered glass, and a wall that leans turns the gap beside it into a wedge that is tight at one end and open at the other. No amount of silicone closes a wedge.
| System | Takes out of plumb | Glass | Fitted, 60 in | Yourself? |
|---|---|---|---|---|
| Framed | 0.5 in | 1/4 in | $680 | An afternoon |
| Semi-frameless | 0.375 in | 1/4, 3/8 in | $1,030 | With care |
| Frameless | 0.25 in | 3/8, 1/2 in | $1,925 | No |
Read the second column as the specification it is. It is why the trade reaches for a framed door when a wall is bad, and why a frameless quote on a crooked opening either includes wall work or is about to become a problem.

A sliding door gives you half the opening
The advice is everywhere: small bathroom, fit a sliding door. The reasoning is sound as far as it goes — a slider needs no floor space outside to open. What nobody follows it with is what a slider costs you on the other side.
Two panels on a track means one of them is always parked in front of the other. The gap you walk through is about half the opening, less the track and the overlap. And the code has an opinion about that: a shower opening has to give at least 22 inches of clear, unobstructed width.
| Opening | Sliding, clear | Panel and door, clear | The slider against the minimum |
|---|---|---|---|
| 36 in | 16 in | 22 in | 6 in short |
| 42 in | 19 in | 22 in | 3 in short |
| 48 in | 22 in | 28 in | clears it |
| 54 in | 25 in | 28 in | clears it |
| 60 in | 28 in | 28 in | clears it |
| 72 in | 34 in | 28 in | clears it |
A sliding door only clears the minimum from about 48 inches of opening upward. Below that the configuration recommended for small bathrooms is the one small bathrooms cannot legally have.

Glass is heavy, and the wall is already tiled
A frameless door looks like it is floating. It is not. It is 74 pounds of glass hanging on two hinges that are bolted through the tile into whatever happens to be behind it.
Glass weighs about 156 pounds a cubic foot, which works out at roughly 13 pounds per square foot for every inch of thickness. That is the whole of the arithmetic, and it produces numbers people are not braced for.
| Glass | Per ft² | A 30 × 72 in leaf | Each hinge | Where it is used |
|---|---|---|---|---|
| 1/4 in | 3.3 lb | 50 lb | 25 lb | Inside framed and sliding kits |
| 3/8 in | 4.9 lb | 74 lb | 37 lb | The standard frameless thickness |
| 1/2 in | 6.5 lb | 98 lb | 49 lb | Heavier frameless, and the one that most often forces blocking |
A framed or sliding door does not have this problem: its load runs down an aluminium jamb screwed the whole height of the wall. Only a frameless door concentrates everything at two points.
Things about the glass that surprise people
- It cannot be cut, drilled or trimmed after tempering. Every dimension, hole and notch is made before the panel is toughened, which is why the template comes after the tiling and not before.
- A chipped edge on delivery is a new panel and another two to three weeks, not a repair.
- The fixed inline panel is usually larger than the door, so most of the glass in the order is the half nobody thinks about.
- A fixed panel of about 30 inches or more wants a brace bar across the top, and it is the part people try to leave off for looks.
- Tempered glass, when it does finally fail, goes all at once into small blunt pieces. That is the standard working as designed, but it is startling if nobody has said so.
- The seals and sweeps along the bottom are consumables with a life of about five years. They are cheap and replaceable, and they are not a fault when they perish.
- Hard water etches untreated glass permanently. A coating delays it and does not stop it for ever.
- The handle is through-bolted, so its position and its holes were decided before the glass existed too.

Framed, semi-frameless, frameless
Once the opening has been measured, this is a genuine choice rather than a showroom one — and the honest summary is that the middle option is right far more often than it gets chosen.
| Framed or sliding | Frameless | |
|---|---|---|
| On a 60 in opening | $680 | $1,925 |
| Tolerates a leaning wall | 0.5 in | 0.25 in |
| Glass | 1/4 in, 3.3 lb a ft² | 3/8 in or 1/2 in, up to 6.5 |
| Needs blocking behind the tile | No — the load runs down a full-height jamb | Yes, and it must be there before tiling |
| How it is bought | A kit, by opening width, glass included | Glass by the square foot plus hardware, piece by piece |
| Time to fit | One visit, two to four hours | Two visits, two to three weeks apart |
| Yourself | A genuine afternoon | No |
| Cleaning | The frame collects everything | Nothing to collect it in |
The case for semi-frameless is that it keeps most of the framed door’s tolerance for a crooked opening — 0.375 of an inch against 0.25 — while losing most of the metal that people object to. On this opening it is $895 less than frameless, it is one visit rather than two, and in a house where the walls are not new it is frequently the only one of the three that fits without paying to correct something.
And the option people forget entirely: no door at all. A fixed screen on this opening is $975. There is nothing to break, nothing to seal along the bottom, and nothing to clean in a track. It only works if the shower is long enough that spray never reaches the gap — but where it works, it is the cheapest and the most durable answer on the page.

What goes wrong
01Choosing the door before measuring the opening
The plumb, the clear opening and the floor outside eliminate most of the catalogue before price is even relevant. Choosing first means discovering one of them afterwards.
Instead — Two minutes with a level and a tape, then shop. The measurements narrow it down to a genuine choice instead of a hopeful one.
02Fitting a slider in a narrow bathroom
It halves the opening. On 36 in that is 16 in to walk through, under the 22 in minimum — in the exact bathrooms the advice is aimed at.
Instead — A hinged door if there is floor outside for it, which gives you nearly the whole opening. Sliders make sense from about 48 in upward.
03Ordering frameless glass for a wall that leans
Frameless tolerates 0.25 in. Beyond that the gap tapers and there is no fix that does not cost money — $220 to correct the wall or $340 to cut the glass out of square.
Instead — Measure first. If it is over the limit, semi-frameless absorbs it in its frame for nothing and looks almost the same.
04Leaving out the blocking
A frameless leaf is 74 lb on two hinges. Without solid timber behind the tile the fixings are in cement board, and it cannot be added afterwards without taking the tile off.
Instead — Decide the door type at framing, not at the end. If it might be frameless, block for it — timber and ten minutes.
05Expecting frameless glass the week the tiling finishes
Tempered glass cannot be altered after tempering, so the panels are cut to a template that can only be taken once the tiling is grouted. That is two to three weeks of a shower you can use but not close.
Instead — Plan for the gap, and tell the tiler frameless glass is coming — it changes how square the work has to be.
06Forgetting the floor outside
A hinged shower door must open outward, so the toilet or the vanity is a hard constraint. It is found on fitting day, when the glass is already cut.
Instead — Measure from the threshold to the nearest obstruction before choosing a configuration. If it is short, the answer is a slider or a screen.
07Fitting a frameless door yourself
It arrives cut to a template with the hinge holes drilled, it cannot be trimmed, and the heaviest panel is 74 lb. A chipped edge is a new panel and another three weeks.
Instead — Do a framed or sliding kit yourself — that genuinely is an afternoon — and pay for the frameless one.
08Treating the coating as permanent
It is a hydrophobic treatment with a life of a few years, occasionally sold as though it were a property of the glass. Untreated glass in hard water etches permanently.
Instead — Take it on hard water, ask what the warranty requires you to do, and expect to renew it rather than never think about it again.
- 01Measure the width three timesWall to wall at the threshold, halfway up, and at the top. Openings are rarely the same at all three. Use the smallest, because that is the one the glass has to pass.
- 02Measure the heightAbout 72 inches for a shower, 58 to 60 over a bathtub. Taller costs the extra glass and nothing else.
- 03Hold the level against each wallSee how far the top sits out from the bottom. This is the number that decides which systems are possible, and it takes a minute.
- 04Measure the floor outsideFrom the threshold to the nearest obstruction — the toilet, the vanity, the opposite wall. A hinged shower door must open outward, so this is a hard limit rather than a preference.
- 05Work out the clear opening, not the glass widthA slider gives you about half. Check it against the 22 inch minimum before falling in love with a configuration.
- 06Decide the door before the tiling startsA frameless door hangs on two hinges bolted into the wall. The blocking behind the tile has to be there already, and it cannot be added later.
- 07Only then choose the systemThe measurements have already eliminated most of the catalogue. What is left is a genuine choice.
The door is the last thing fitted and one of the first things that has to be decided, because the blocking behind the tile and the squareness of the opening are both settled long before anybody measures for glass. That page prices the shower from the tiled wall area — which is four to five times the footprint — and names the detail that half of failed showers are missing.
If the shower itself is still being built- Out of plumb
- How far a wall leans off vertical, measured as the distance the top sits out from the bottom. It is the measurement that decides which door systems can be used, and almost nobody takes it before ordering.
- Clear opening
- The width you actually walk through once a panel is parked or a door is hinged out of the way — not the width of the glass. Code asks for at least 22 inches at a shower.
- Bypass
- A sliding door: two panels on a track, one passing behind the other. It needs no floor space outside and it gives back roughly half the opening.
- Inline panel
- A fixed sheet of glass beside a hinged door, the usual frameless answer on a tub-sized alcove. It is normally the larger half of the glass order.
- Tempered glass
- Heat-treated safety glass, required in every shower enclosure. It cannot be cut, drilled or notched after tempering, so every dimension and hole is made before the panel exists.
- Template
- A measured pattern of the finished opening taken after the tiling is grouted. The frameless panels are cut to it, which is why frameless glass arrives weeks after the shower is otherwise usable.
- Blocking
- Solid timber fixed between the studs before the wall is closed up, so a hinge or a grab rail has something to bite into. It cannot be added once the tile is on.
- Header or brace bar
- A bar across the top of a frameless enclosure that stops a tall fixed panel working loose at its clamps. It is the piece people most want to leave off.
- U-channel
- An aluminium channel the edge of a fixed panel sits in, as an alternative to clamps. It hides a little more of a wall that is not straight, which is occasionally the whole reason to use it.
- Sweep
- The flexible strip along the bottom edge of a swinging door that stops water running out. It is a consumable and it will want replacing in about five years.
- Semi-frameless
- Framed where the glass meets the walls and bare on the door edges. It keeps most of a framed door's tolerance for a crooked opening and loses most of the metal.
- Category II glazing
- The safety class that shower doors and tub enclosures have to meet under federal rule, which in practice is what makes every piece of glass in one tempered.
Common questions
- How much does shower door installation cost?
- On a standard 60 inch opening: about $680 for a framed sliding door fitted, $1,030 semi-frameless, and $1,925 for a frameless fixed panel and hinged door. A plain walk-in screen with no door at all is about $975. The spread is mostly glass thickness and labour: a framed kit is one visit, a frameless door is two visits and two people.
- How much does it cost to replace a shower door?
- The same as fitting one, plus almost nothing to take the old one off — an hour and some patience with the silicone. What makes a replacement different is that the opening already exists and has usually moved: walls settle, and a door that fitted in 1998 is not evidence that the opening is square now. Measure the plumb before ordering. It is the difference between a $680 job and one that needs $220 of wall correction first.
- Why is a frameless shower door so much more expensive?
- Three reasons, and only one of them is the glass. It is thicker — 3/8 in at 4.9 lb a square foot against 1/4 in at 3.3 — so the material is roughly double. The hardware is bought piece by piece rather than coming in a box. And the labour is two visits instead of one, because the panels are templated after the tiling is finished and come back two or three weeks later. On this opening that is $1,245 more than a framed slider.
- Does my shower opening have to be perfectly plumb?
- For a framed door, no — the frame absorbs about 0.5 of an inch and that is what frames are for. For frameless, effectively yes: 0.25 of an inch is the practical limit, because the glass is a rectangle and a leaning wall turns the gap into a wedge. Beyond that you either correct the wall for about $220 or have the glass cut out of square for about $340.
- Is a sliding door better for a small bathroom?
- It is the standard advice and it is usually wrong. A sliding door needs no floor space outside, which is the argument for it — but one panel is always parked in front of the other, so you walk through about half the opening. On a 36 inch opening that is 16 inches, well under the 22 inch code minimum, while a single hinged door on the same opening gives you nearly all of it. A slider only clears the minimum from about 48 inches of opening upward.
- How much does a frameless shower door weigh?
- More than people expect. 3/8 in glass is 4.9 lb per square foot and 1/2 in is 6.5, so a 30 × 72 in door leaf is 74 lb in 3/8 in and 98 lb in 1/2 in. That hangs on two hinges bolted through the tile — about 37 lb each — and anything over roughly 40 lb wants solid blocking behind the substrate.
- Can I install a shower door myself?
- A framed or sliding kit, yes — it is a genuine afternoon with a level, a drill and a helper, and the frame forgives a wall that is not quite straight. A frameless door, no. The panel arrives cut to a template with the hinge holes already drilled, it cannot be trimmed, it weighs as much as a person's upper body, and if an edge chips on the way in it is a new panel and another three weeks.
- How long does it take to fit a shower door?
- A framed or sliding door is two to four hours in one visit. A frameless door is two visits with two to three weeks between them: the template can only be taken once the tiling is grouted, and the glass is cut, tempered and shipped to that template. Plan for a shower that works but cannot be closed during the gap.
- Which way does a shower door open?
- Outward. A hinged shower door has to open outward under the code, so that somebody who falls against it does not seal themselves in. That makes the clear floor outside the enclosure a real constraint rather than a preference — and in a small bathroom it is usually the toilet or the vanity that decides whether a hinged door is possible at all.
- Do I need blocking behind the tile for a shower door?
- For a framed or sliding door, no — the load spreads down a full-height aluminium jamb screwed the whole way up the wall. For a frameless door, yes: the entire weight arrives at two points. The catch is the sequence. Blocking goes in while the wall is open, the door is fitted at the very end, and nobody connects the two — so the decision about which door you want has to be made at framing, months before anybody looks at glass.
- Is the protective glass coating worth it?
- On hard water, yes. It is a factory-applied hydrophobic treatment that stops minerals etching into the glass surface, and untreated glass in a hard-water area goes permanently cloudy in a few years. What it is not is permanent — it wears, it has a life of a few years, and it is sometimes sold as though it were a property of the glass rather than a coating on it. Ask how long the warranty runs and what it requires you to do.
- What size shower door do I need?
- Doors are sold to fit a range of openings, not an exact size, because openings are never exactly anything — a "56 to 60 inch" kit has adjustment built into its frame. Measure the width at the bottom, the middle and the top and use the smallest. For frameless there is no range: the glass is cut to your opening from a template, which is exactly why the opening has to be measured properly first.
