Shower Remodel Cost: What Actually Sets Your Number
Want your number first? Open the free Square Footage Calculator, or read on for how it works.

Shower remodel cost is not one number, because a shower remodel is not one project. There are four honest routes, and they are separated by how far past the surface you go: a refresh that regrouts, recaulks, refinishes and swaps the trim; an acrylic overlay installed over the shower you already have; a full replacement in the same footprint, either prefab or tiled; and a rebuild that changes the footprint or moves the drain. Those four routes involve different trades, different permits, different timelines and a completely different amount of work, which is why a single average is close to useless.

The dividing line that matters most is the drain. As long as the drain stays where it is, you are doing a finish job that one crew can handle. The moment it moves, you are opening a floor, involving a licensed plumber, scheduling an inspection, and possibly touching framing, and all of that happens before anything decorative gets installed.

A note on numbers. This page gives you the routes, the line items, the quantities and the bid questions, not dollar figures. Tile, glass, fixtures and plumbing labor are priced locally and they move constantly, and we do not set any of them. Work out your route and your quantities here, then take an identical written scope to three local pros.

What shower remodel cost depends on before anyone quotes

Every quote you receive is really an answer to six questions about your bathroom. Answer them yourself first and the quotes stop looking random.

  1. Does the drain stay put? This is the largest single fork in the whole project. A drain that stays is a finish job. A drain that moves is a plumbing job with a finish job attached.
  2. Is the substrate sound? Press the tile near the base and along the corners. Flex, a hollow sound, or a soft spot means the wall behind the tile is wet, and any route that covers it instead of removing it is buying you a year or two.
  3. Has the pan failed? Staining on the ceiling below, or on the baseboards on the far side of the wall, is pan or membrane failure. That rules out a surface fix.
  4. Prefab or tiled? A multi piece acrylic or fiberglass unit is one product with one install. A tiled shower is a substrate, a waterproofing system, a pan, tile, setting labor and glass, and it takes a different crew a much longer time.
  5. How much glass? Custom frameless enclosures are templated after the walls are finished, fabricated off site, and installed on a second visit. A stock semi frameless door is off the shelf. A curtain rod costs almost nothing. This is the easiest place in the whole project to change the total.
  6. What is the access like? A first floor bathroom near a door is straightforward. A second floor bathroom at the top of a turned staircase means every piece of debris and every sheet of board is carried by hand.

The four routes, and what separates them

Find your row first. Everything below applies to one or two of these rows, not all four.

Route What it covers Trades involved Time Drain moves?
1. Refresh in place Regrout, recaulk, refinish or reglaze the base and walls, new door or curtain rod, new valve trim and head, new drain cover DIY or one handyman 1 to 3 days No
2. Overlay or liner system Acrylic or PVC wall panels and a fitted base installed over the existing shower, new door, new trim One factory trained crew 1 to 2 days No
3. Replace in place, prefab Demo the old shower, new pan and multi piece acrylic or fiberglass unit in the same footprint, new valve, new door, patch and paint Plumber plus carpenter, sometimes a painter 3 to 7 days No
3b. Replace in place, tiled Demo, new substrate, waterproofing membrane, tiled walls and floor, new pan or mud bed, glass, new valve Plumber, tile setter, glass fabricator 1 to 2 weeks No
4. Rebuild with a layout change Everything in 3b plus a larger footprint, a curbless entry, a bench, moving the drain or the valve wall, sometimes structural work in the floor All of the above plus a framer, an inspector, sometimes an engineer 2 to 4 weeks Yes

This article is about changing a shower you already have. If you are pricing a shower going into a new or gutted bathroom, the unit by unit breakdown is in shower installation cost, and the room wide picture across all trades is in bathroom remodel cost.

Which route your shower actually needs

A dated shower and a failing shower look similar and need opposite answers. Run these three tests before you pick.

The refresh route, line by line

This is the underrated option, and it is the cheapest route by a wide margin. A shower with a sound pan and sound walls that simply looks tired can be transformed in a weekend.

Item What it involves as DIY What changes when it is hired
Regrout walls and floor Grind out the old grout, vacuum, mix and float new grout, wash the haze Priced by the hour or by the shower, and a pro removes grout faster without chipping tile edges
Replace all caulk joints Cut out old sealant, clean and dry the joint, tool a fresh bead Small job, usually bundled into another visit rather than sold alone
Refinish or reglaze a fiberglass or cast iron base Kit work with real ventilation and real protective gear Sprayed coatings and better prep, and a warranty that a kit does not carry
Refinish tiled walls with an epoxy coating The most demanding DIY item on the list, and the least forgiving of poor prep Rarely offered alone, usually part of a full refinishing package
New door or enclosure Semi frameless doors are homeowner installable in an afternoon Frameless glass is templated and installed by the fabricator, never by you
New valve trim kit and shower head Trim only, no wall opening, if the new trim matches the existing valve brand A plumber becomes necessary the moment the valve body itself is changed
New drain cover and escutcheons Minutes, with the right size Folded into any of the above

Two honest limits on this route. Reglazing a base buys five to ten years, not a lifetime, and it fails at the drain flange first. And a refinished surface cannot be cleaned with abrasives, ever, so hand the household a bottle of non abrasive cleaner on day one or you will be doing it again.

The highest value item on the list is the caulk, and it is also the cheapest. A shower fails at the change of plane joints far more often than in the field, so one tube of the right sealant applied properly is genuine preventive maintenance rather than decoration. The method is in how to caulk a bathtub, and it applies identically to a shower base.

Overlay and one day systems, assessed honestly

The national bath remodel brands sell an acrylic or PVC wall surround and a fitted base that install over your existing shower in a day or two. The pitch is speed, and the speed is real.

What you get: a fast, low maintenance, genuinely waterproof surface with almost no disruption, and usually a long warranty on the material itself.

What you should check before signing:

These systems are a reasonable buy when the existing shower is structurally fine, when disruption is the binding constraint, or when the household cannot lose a bathroom for a week. They are a poor buy when the substrate is compromised.

Replacing in place: where the work actually goes

Route 3 is the most common real remodel. The footprint stays, the drain stays, and everything else is new. Here is what appears on the proposal, and what makes each line bigger or smaller.

Line item Keeps it lean Pushes it up
Demolition and disposal Fiberglass unit, ground floor, easy path out Tile and mortar bed, cast iron base, second floor, long carry
Valve and rough plumbing New valve in the existing location, accessible from behind Copper repipe, old galvanized supply, no access panel, drain in a finished ceiling
Substrate Cement board on flat, square framing Foam board systems, out of plumb walls, framing repairs first
Waterproofing Prefab unit with the waterproofing built in Full membrane or liquid applied system, curb, niche and bench detailing
Base or pan Stock size prefab base on a level floor Site built mud bed, linear drain, custom size, curbless recess
Wall surface Multi piece acrylic or large simple field tile Small format, mosaic, herringbone, natural stone, accent bands
Glass or enclosure Curtain rod or a stock semi frameless door Custom frameless, low iron glass, notched panels, oversize openings
Trim and accessories Single function valve trim and one head Thermostatic valves, body sprays, hand shower on a slide bar, multiple niches
Patch, paint, punch list Work confined inside the shower opening Ceiling repairs below, damaged flooring, repainting the whole room

The waterproofing line is the one to protect. It is a small share of the job and it is the entire difference between a shower that lasts twenty years and one that rots a subfloor in five. Tile is not waterproof and grout is not waterproof. The system underneath is, and it has to be continuous through every corner, the curb and the drain connection. The full sequence is in how to tile a shower.

When you also need a permit

Replacing a shower in the same location with no plumbing changes typically needs no permit in most US jurisdictions. You cross the line when any of these apply:

Walk in shower remodel cost and what makes it different

Converting to a walk in, meaning a low curb or curbless entry with a wide opening, is the most requested change and the most misunderstood.

Version What drives it Structural work?
Low curb walk in, standard alcove, prefab base Same footprint, existing drain, stock base, one glass panel No
Low curb walk in, tiled Tile labor, full waterproofing, larger glass panel No
True curbless, tiled, drain stays Floor recess, linear drain, slope in two directions Usually, on a framed floor
Curbless with the drain relocated or the footprint enlarged Plumbing relocation, framing, permits, inspections Yes, and often an engineer's sign off

The reason curbless costs more is not the missing curb. It is that the shower floor has to sit lower than the bathroom floor so water runs the right way. That means either recessing the framing, which is structural work on the joists and needs an engineer's review in most cases, or building the whole bathroom floor up so the shower becomes the low point. Both are real construction, not finish work.

A detail that saves real money: on a slab on grade first floor, curbless is often far cheaper, because there are no joists to modify. On an upper floor over a finished ceiling, it is usually the expensive version.

Accessibility work is worth doing properly at the same time. Blocking behind the walls for grab bars adds almost nothing while the walls are open, and it is disproportionately expensive to add later. Put it in even if nobody needs a grab bar this year.

Build your own estimate: the quantities a calculator actually uses

Skip the online calculators that ask for a zip code and an email address. The arithmetic behind them is quantity math, and you can run it in five minutes on a standard 60 by 32 inch alcove tiled to 80 inches. Quantities are the part of an estimate that should match exactly between your math and a contractor's.

Step 1: wall area. Wet wall run = back wall 60 in + side wall 32 in + side wall 32 in = 124 in Wall area = 124 x 80 = 9,920 sq in 9,920 / 144 = 68.9 sq ft of wall tile

Step 2: waste allowance, on its own line. Straight stacked or brick set on a simple alcove: 15 percent, because a shower is a cut up space with a niche, a curb and three inside corners. 68.9 x 0.15 = 10.3 sq ft Order = 68.9 + 10.3 = 79.2, so buy 80 sq ft

Step 3: floor area. 60 x 32 = 1,920 sq in 1,920 / 144 = 13.3 sq ft Waste allowance at 10 percent for a small mosaic floor = 1.3 sq ft Order = 13.3 + 1.3 = 14.6, so buy 15 sq ft

Step 4: turn quantities into comparable bids. You now have two hard numbers, roughly 80 sq ft of wall tile and 15 sq ft of floor tile, plus about 95 sq ft of setting labor. Put those figures in the scope you hand every bidder. If one proposal assumes a different square footage, you have found a real difference in what is being built rather than a difference in price. Our tile calculator does the same math for odd shapes, niches and accent bands.

Raise the waste allowance to 20 percent for diagonal, herringbone or large format layouts, and buy all of it in one order so the tile comes from a single production run. A second order weeks later can arrive a shade off, and there is no fixing that after the fact.

What moves your number most

Ranked by how much they change the total on a typical job.

  1. Moving the drain. The single largest swing available, and it drags a permit, a licensed plumber and an inspection window along with it. It costs far more on an upper floor than on a slab.
  2. Glass. A custom frameless enclosure is the priciest option, a semi frameless door is well below it, and a curtain is the cheapest way to close a shower opening. This is the easiest line to change without touching anything structural.
  3. Tile size and pattern. Large format tile needs a flatter substrate and often floor leveling. Herringbone and diagonal layouts add cuts, labor and waste, which is why the waste allowance climbs.
  4. Region. Labor is half to two thirds of a tiled shower, and labor is priced locally. The same scope varies enormously between low cost and high cost US markets, and no published range crosses that gap usefully.
  5. What is found behind the wall. Rot, failed framing, old galvanized supply lines, or a cast iron drain stack in the way. This is exactly why the contingency exists.
  6. Finish level. Builder grade valve trim is the least expensive fixture in the bathroom. A designer thermostatic system with body sprays needs a bigger valve, sometimes a bigger supply line, and possibly a larger water heater, so the fixture is only part of what it changes.

Build in a contingency, and say the number out loud

Set aside 10 to 15 percent of your budget on a route 3 job and 15 to 20 percent on a route 4 job. Older houses run at the top of that band. The contingency is a separate line in your budget, never folded into the base number, because a budget that has already spent its contingency is not a budget.

Worked example: a 1990s fiberglass alcove, three ways

A 60 by 32 inch one piece fiberglass unit in a 5 by 8 hall bathroom. The pan is sound, the surround is dull and stained, the door is a sliding frame full of hard water deposits.

Option A: refresh, DIY. A refinishing kit, fresh caulk, a stock semi frameless door, a new valve trim kit and head, and a new drain cover. One long weekend of work, the least expensive route by a wide margin, and it buys roughly five to eight years. The bathroom stays usable most of the time.

Option B: replace in place with a multi piece acrylic unit, hired. Demo and disposal, a new base and three piece surround, plumbing at the existing locations, install labor, a new door, trim and head, plus drywall patch and paint. Four to six days with the bathroom out of service, and roughly an order of magnitude more than option A. Add a contingency of about 12 percent on top of the quoted subtotal.

Option C: tear out and tile, hired. Demo and disposal, substrate and waterproofing, a pan and linear drain, about 95 sq ft of tile including the waste allowance, tile setting labor, a glass panel, plumbing, trim, paint and a punch list. Ten to fourteen days, the most expensive of the three, and the only one that gives you a fully rebuilt wet wall. Carry a contingency near 15 percent.

Option A is the right answer more often than the industry likes to admit. Option C is the right answer when the pan has failed, when you are staying ten years, or when the bathroom is being redone anyway.

What belongs in the scope of work

Do not accept a one line proposal. Ask for these items written out, and hand every bidder the same list so the comparison means something.

  1. Route. Refresh, overlay, replace in place, or layout change, stated plainly.
  2. Demolition and disposal. What comes out, how it leaves the house, and who pays the dump fees.
  3. Substrate. Product name and thickness, and what happens if wet or damaged framing is found.
  4. Waterproofing. The named system, and how the corners, the curb, the niche and the drain connection are detailed.
  5. Pan. Stock prefab base, site built mud bed, or a foam tray, and the drain type that goes with it.
  6. Tile. Square footage of wall and floor, the waste allowance as its own line, and who supplies the tile.
  7. Plumbing. Valve make and model, whether the valve body is replaced, and whether anything moves.
  8. Glass. Stock door or templated custom, the glass thickness, and the lead time between template and install.
  9. Permits. Which ones, who pulls them, and how inspection days affect the schedule.
  10. Patch and paint. How far outside the shower opening the repair work extends.
  11. Schedule. Working days, the gaps for cure time and glass fabrication, and how long the bathroom is unusable.
  12. Warranty. Separate terms for material, labor and water intrusion, in writing.

Questions to ask each bidder

Three bids on that identical scope tell you far more than any published average. If one comes in dramatically under the others, the difference is almost always the waterproofing, the substrate, or the glass. Our how to get contractor bids page has the wording that produces matched quotes, and contractor red flags covers the verification steps before you sign anything.

Frequently asked questions

What is the average cost of a shower remodel?

There is no useful average, because the four routes are genuinely different projects with different trades and different timelines. A refresh and a curbless rebuild are not variations on one job. Pick your route from the table above using the flex test, the leak test and the use test, then get three written quotes on that route with an identical scope. That comparison is far more accurate than any national figure could be.

How much does it cost to replace a shower without moving the drain?

Keeping the drain in place is the single biggest saving available in a shower project, because it avoids opening the floor, hiring a licensed plumber and pulling a plumbing permit. A prefab replacement in the existing footprint is substantially cheaper than a tiled one, and both are far cheaper than any version where the drain moves. Design around the existing drain location if the budget is tight.

Is a walk in shower more expensive to remodel into?

A low curb walk in in the same footprint costs about the same as any other replacement of the same type. A true curbless entry is the expensive version, because the shower floor has to sit below the bathroom floor. On a framed floor that means recessing the joists, which is structural work needing an engineer in most cases, or building up the surrounding floor instead. On a slab, curbless is much less of a jump.

Can I remodel a shower myself?

The finish work, yes. Demolition, substrate, tile setting and trim are all learnable. The two parts to think hard about are the waterproofing system, where a hidden mistake shows up years later as a ceiling repair, and any plumbing change, which is licensed work in most jurisdictions. A common split that works well is hiring a plumber for the valve and the drain and doing the tile yourself.

Do I need a permit to remodel a shower?

Not usually for a like for like replacement in the same location with no plumbing or electrical changes. You do need one to move the drain or supply lines, to add or relocate an exhaust fan or lighting, or to alter framing. Condos and co-ops add a building approval on top. Rules vary by city and county, so confirm with your local building department before demolition starts.

How long is my bathroom out of service?

One to three days for a refresh, one to two days for an overlay system, three to seven days for a prefab replacement, and one to two weeks for a tiled build. A layout change with a moved drain runs two to four weeks because of inspection scheduling between rough in and close up, plus the glass fabrication gap. Households with one bathroom should build the plan around this rather than around the budget.

Is it worth regrouting instead of replacing?

Yes, when the substrate behind the tile is sound and the pan is not leaking. Regrouting and recaulking is the cheapest thing you can do to a shower and it can add years to a tired but healthy one. Test first: press on the tile near the base and in the corners, and look for staining on the ceiling below. Any flex or any stain means the problem is behind the grout, and new grout will not fix it.

Does a shower remodel add value to a house?

A dated or leaking shower is a visible negative at resale, so fixing it protects value more than it creates it. Mid range bathroom work returns a meaningful share of its cost at sale, and that share falls as the finish level rises above the neighborhood standard. Spend at your neighborhood's level, not above it, and put the money into the waterproofing and the layout rather than into the fixtures.
