Tub to Shower Conversion Cost, and What It Costs to Go Back

Almost every page that will tell you what a tub to shower conversion costs is published by someone who sells tub to shower conversions. That is not a conspiracy, it is just how the category works. The search term is worth money to remodelers, so remodelers write the cost guides, and the number they land on tends to be the number that makes their own quote look reasonable.

⚑ FLAGGED FIRST-PARTY CLAIM, needs Bryan's confirmation before publish: Badeloft manufactures stone resin bathtubs. We do not sell, quote or perform conversions in either direction. Which means the arithmetic below has no thumb on the scale. This guide prices the job the way an estimator does, line by line, using published national cost data from HomeAdvisor and Fixr, the plumbing requirements written into the International Residential Code, and the real invoice numbers homeowners and contractors post in renovation forums when nobody is selling anything.

By a conversion we mean both directions: pulling a tub out and putting a shower in, which is the job most people are searching for, and taking a shower out and putting a tub back, which is the job almost nobody writes about carefully because almost nobody sells it.

If you are holding a quote and cannot tell whether it is fair, the ledger below lets you check it against the specific lines your bathroom actually triggers. If you live in a house with one bathroom and one tub, read the resale section first, because that decision is harder to reverse than it looks. And if you took the tub out years ago and now have a toddler and second thoughts, the second half of this guide was written for you.

By the end you will have a per-line estimate for your own bathroom, the four line items that cause most of the surprise on a final invoice, and a clear read on which direction makes sense for your house rather than for the person standing in it with a clipboard. We have grouped it into four parts: what the job costs and what sits inside that number, why the same bathroom gets quoted at wildly different prices, what the reverse conversion costs, and how to decide which direction is yours. Let us start with the number you came for.

What a Tub to Shower Conversion Costs Right Now

A tub to shower conversion costs $2,850 to $7,600 for a prefabricated shower installed in the tub's existing footprint, and $6,250 to $15,550 for a tiled shower with the drain relocated and a glass door. A curbless shower in natural stone, with the layout changed, runs from $15,000 to $33,500. Those three bands come from the line-item model further down this page, and you can adjust every line in it to match your own bathroom.

Now the part no other cost guide will show you. Here is what the seven pages currently ranking for this search each call the average.

Source	What it calls typical	Full range given	Last updated	Who publishes it
HomeAdvisor	$3,000	$1,200 to $15,000	June 2026	Lead-generation marketplace
Fixr	$4,000	$1,200 to $20,000	January 2025	Lead-generation marketplace
The Home Depot	$8,000 to $15,000	not given	not stated	Retailer selling the service
Express Bath	not given	$1,200 to upwards of $10,000	not stated	Regional remodeler

TubcuT	$4,000 to $9,000	$1,200 to $8,000	February 2026	Sells a tub-cut insert

The stated average for the same job ranges from $3,000 to $15,000 depending on which page you land on. The Home Depot figure comes from Google's rendered snippet of their services page, which blocks automated access, so treat it as reported rather than read. Nobody explains the spread, and the spread is the most useful thing on the page: it tells you that "average" is doing almost no work here, and that the only number worth having is the one built from your own bathroom.

One clarification worth making early, because the two jobs get conflated constantly. This is not the same project as swapping a tub for another tub. A like-for-like replacement reuses the drain position, the wall opening and usually the surround. A conversion changes the drain, the waterproofing and the entire wall surface. They are priced differently because they are different jobs.

The Eleven Lines Behind Every Conversion Quote

Every conversion quote, whatever the headline number, is built from the same eleven lines. Your job is not to know the national average. Your job is to know which of these eleven your bathroom actually triggers, because a quote for a job that fires seven of them should not be compared against a quote for a job that fires eleven.

Line	Typical range	What decides it
Tub removal and demolition	$150 to $1,100	Cast iron has to be broken up in place, which roughly doubles this line against acrylic
Debris haul-away	$100 to $200	Bundled by some crews, billed by weight by others. Ask which
Drain relocation and rough plumbing	$150 to $2,400	Whether the drain moves, and whether it moves within a joist bay or through a slab
Waterproofing and substrate	$150 to $2,400	The single largest invisible line. A prefab kit needs almost none, a curbless tiled build needs a bonded sheet membrane
Shower base or pan	$300 to $2,600	A prefab pan is a product. A tiled pan is three days of labor
Wall surface	$600 to $9,000	The widest line by a distance, and the one that most quotes describe least precisely
Glass enclosure or door	$300 to $2,800	Framed, semi-frameless or frameless. Frameless glass alone can move a quote by $1,500
Valve, showerhead and trim	$150 to $2,600	Reusing the old valve saves money now and means opening finished tile later
Niche, bench and grab bars	$100 to $1,700	Often quoted as extras rather than included
Installation labor	$900 to $7,500	Everything above that is not a product you can hold in your hand
Permit and inspection	$100 to $1,200	Required anywhere a drain, a vent or a wall moves

Ranges are drawn from HomeAdvisor's cost data updated June 2026 and Fixr's material tables, cross-checked against owner-reported invoices in renovation forums. The pan line is worth reading about separately if you are still deciding, because choosing a shower tray or pan sets the ceiling on several of the lines beneath it.

Picture a 1978 ranch with a 30 by 60 alcove and a cast iron tub. The homeowner gets a quote for a tiled walk-in and reads $9,400. What she does not see is that four of those eleven lines are doing most of the work: the cast iron has to be sledged out in sections rather than carried, the drain has to shift about fourteen inches toward the centre of the pan, the tile build needs a proper membrane rather than a plastic liner, and the labor line is a tile crew's week rather than a fitter's afternoon. The same bathroom with an acrylic tub, a pan that reuses the drain and a prefab surround would have quoted near $4,000. Nothing changed about the room. Four lines changed about the job.

Run your own bathroom through the ledger below. Uncheck the lines your job does not trigger, set the level for the ones it does, and it will price both directions.

Why the Same Bathroom Gets Quoted at $4,000 and at $14,000

Three things drive almost all of the spread: the wall surface, whether the drain moves, and the business model of the company holding the clipboard. The first two are physical and you can price them. The third is not, and nobody selling you a conversion is going to explain it, so here it is.

The most aggressively marketed version of this job is the one-day bathroom conversion: an acrylic pan and a three-piece wall kit installed over the existing substrate, sold at a fixed price by a national franchise with a large advertising budget. On a public forum thread about an $11,000 quote for exactly that product, an installer who buys the same kits described his own cost: "my cost from the distributor before shipping is $1,700 for a basic kit with two grab bars. Two shelves, a pan and three walls." That gap is not fraud. It covers labor, warranty, overhead, and the marketing that put the salesperson in the living room. But a homeowner comparing that $11,000 against a $6,000 quote from a local tile crew is not comparing two prices for one job. They are comparing two entirely different businesses.

The forums are full of people trying to work this out in real time. A contractor breaking down a $14,000 quote put it in line items: "you are looking at $1k to $2k of tiles, $2-3K of water proof." Another, in a thread about a franchise quote in West Michigan, said flatly that it "should be closer to 10-12k." A Chicago contractor on Houzz quoted $11,000 in labor alone to take out a 30 by 60 tub and build a custom tile walk-in. And a homeowner on r/AskContractors summed up why any of this is hard to research at all: "I do not want to be deluged by five hundred tub to shower contractors by clicking a link in social media. I am curious. The videos seem very slick."

Say you get three quotes on the same bathroom: $4,200, $8,900 and $14,000. Left as headline numbers they look like one contractor is cheap and one is gouging. Broken into the eleven lines, the $4,200 turns out to be a prefab kit over the existing drain with no permit pulled, the $8,900 is a tiled build with a moved drain and a framed door, and the $14,000 is the same tiled build sold by a franchise with a lifetime labor warranty and a call centre. All three can be fair prices. Only one of them is a price for the bathroom you actually want.

A useful sanity check: a conversion should not cost more than what a full bathroom remodel runs in your market. If it does, you are being quoted for a remodel and being told it is a conversion.

The tool below inverts the ledger. Instead of pricing what a quote includes, it prices what a quote stayed quiet about, which is where change orders come from.

What It Costs to Put a Bathtub Back In

Converting a shower back into a bathtub costs $3,600 to $9,750 for an alcove tub in the shower's existing footprint, and $7,450 to $14,900 if you are setting a freestanding tub with new supply lines and a floor-mounted filler. The one page currently ranking for this direction prices it at $1,200 to $3,000, which is below every credible source for the forward conversion despite being, physically, a comparable amount of work. That page is published by a company that sells the service, and a low anchor number gets the phone to ring.

The reverse job has its own ledger, and it is not the forward one run backwards.

Line	Typical range	What decides it
Shower and pan demolition	$200 to $1,200	A tiled pan on a mud bed is far heavier work than lifting an acrylic base out
Debris haul-away	$100 to $250	Mud bed and tile debris is dense and often billed by weight
Drain rework and P-trap	$250 to $2,800	A tub drain sits lower and further from the wall than a shower drain, so this line fires almost every time
Framing, alcove or floor support	$0 to $2,800	Zero if the alcove is still there. Real money if you are building one or reinforcing for a heavy soaking tub
Waterproofing and substrate	$200 to $1,600	Lower than the forward direction, because a tub carries most of the water itself
The tub	$400 to $7,000	A basic acrylic alcove tub near the bottom, a cast iron freestanding at the top
Surround or wall surface	$250 to $4,000	A freestanding tub needs paint and patch. An alcove tub needs a full surround
Filler, valve and trim	$200 to $2,400	Floor-mounted freestanding fillers are their own budget line
Finished floor repair	$200 to $2,600	The old pan footprint almost never matches the surrounding floor
Installation labor	$900 to $6,500	Setting and levelling a heavy tub is slower work than dropping in a pan
Permit and inspection	$100 to $1,200	Moving a drain triggers this in nearly every jurisdiction

Two things about this ledger surprise people. The first is that the tub is often not the biggest line. Badeloft's own freestanding stone resin tubs currently run $3,290 to $3,890 across 27 models, live pricing as of September 2026, which on a $12,000 job is a quarter of the total and less than the combined plumbing, framing and labor. The second is that a freestanding tub can be cheaper to install than an alcove one, because it deletes the surround, the tiled walls and the glass from the ledger entirely. You pay more for the fixture and less for the room.

Picture a couple who converted their only tub to a walk-in shower in 2019 because the tub sat unused and the shower looked better. Four years later there is a two-year-old in the house and bathing her means kneeling over a kitchen sink. They price the reverse: the alcove framing is long gone, the drain has to come back out toward the wall, the pan tiles have to be lifted and the floor patched. The quote lands at $9,200, roughly what they spent removing it, and none of that money bought them anything they did not already have in 2019. The lesson is not that they made the wrong call. It is that this decision has a round-trip cost, and the round trip is close to full price both ways.

If you are doing this yourself or want to understand the sequence before you get quotes, the mechanics of removing and replacing a bathtub cover the physical steps this ledger prices.

The Drain and the Code Nobody Quotes You On

Two technical facts decide whether your conversion passes inspection, and neither appears on any of the pages currently ranking for this search.

Your new shower has a minimum legal size. Under section P2708.1 of the International Residential Code, a shower compartment must have at least 900 square inches of interior cross-sectional area and measure at least 30 inches in its smallest dimension, measured from the finished interior surfaces, excluding valves, showerheads, soap dishes and grab bars, and that clearance has to continue to a height of 70 inches above the drain. There is an alternative for narrow spaces: 25 inches minimum dimension is permitted if the compartment provides at least 1,300 square inches. Hinged shower doors must open outward. A standard 30 by 60 alcove clears this comfortably. A narrow bathroom where someone wants to steal a few inches for a vanity does not always, and that is where retrofits fail inspection.

Your drain is probably the wrong size. A bathtub drains through a 1.5 inch line. A dedicated shower is conventionally plumbed with a 2 inch drain, because a tub holds its own water while a shower has to carry the full flow away continuously. A standard showerhead moves 2.5 gallons per minute, and one that carries the EPA WaterSense label is capped at 2.0. Multiply that by a rainhead plus body sprays and the reason for the larger line becomes obvious. Codes differ here, and the nuance matters: the plumbing code permits a 1.5 inch drain for a combination tub and shower, which is what you currently have. Convert to a dedicated shower and many jurisdictions will want the 2 inch line, which means opening the floor. That is the single most common source of a mid-job change order.

Both of these are reasons to pull the permit rather than avoid it. A conversion done without inspection is a conversion the next buyer's inspector finds, and when a bathroom remodel needs a permit is worth reading before you agree to a quote that quietly leaves the permit line off.

Beyond code, three things get found behind an old tub often enough that you should hold money for them: a rotted subfloor under the drain, a failed pan liner or flange seal in the wall, and framing that was never sized for what is going in. Hold 10 to 15 percent of the high end of your quote in reserve. On a $9,000 job that is $900 to $1,350 that you hope not to spend.

What Removing Your Only Tub Does to Resale

Removing the only bathtub in a house narrows your buyer pool. It does not trigger an automatic appraisal deduction, because appraisers work from square footage, condition and comparable sales rather than a fixture checklist. The risk is commercial, not technical: families with small children and buyers who bathe will filter your listing out before they ever see it, and in a slow market that shows up as time on market rather than as a lower appraisal.

The industry's own benchmark is worth knowing. The Cost vs. Value report's midrange bathroom remodel, the specification that reportedly recoups around 80 percent nationally and posts the strongest interior return in the study, is defined as a project that includes a new bathtub. That recoup figure is widely reported but the primary report is behind an access wall, so treat the 80 percent as reported rather than verified. Separately, the National Association of Realtors 2025 Remodeling Impact Report places bathroom renovation among the top three projects showing increased demand among its members over the previous two years, at 35 percent. Bathrooms are worth doing. The question is which bathroom you are left with.

Here is where the answer genuinely forks.

If this is the only tub in the house, keep a tub somewhere. Not necessarily this one and not necessarily in this room, but somewhere. If the house has two full bathrooms and the tub is in the hall bath, converting the primary bath to a shower is the standard move and carries almost no resale risk. If the house has one full bathroom and one tub, converting it is the version that costs you buyers, and it is also the version that is most expensive to undo.

If there is already a second tub elsewhere, the resale argument mostly evaporates and you should decide on how you actually live. A large tiled walk-in shower in a primary bathroom is a desirable feature in most markets, and designing a primary bathroom with no tub at all is a legitimate design direction rather than a compromise.

Picture a 1990s two-bath colonial: a tub-shower combo in the hall bath and a second tub-shower combo in the primary. Converting the primary to a walk-in leaves a tub in the house, gives the owners the shower they use every day, and costs them nothing with a family buyer who will look at the hall bath and move on. Now picture the same conversion in a 1,100 square foot bungalow with one bathroom. Same job, same price, entirely different consequence: every buyer with a small child now has a reason to keep scrolling.

The fuller version of this argument, with the market data, sits in our breakdown of how tubs and showers compare on resale value.

Doing It Yourself Versus Hiring It Out

Doing the work yourself saves roughly $2,000 to $5,000 in labor on a typical conversion, and the saving is real. What decides whether it is a good idea is not your skill with tile. It is which of the eleven lines you are actually allowed to touch.

If the drain stays exactly where it is and you are installing a prefabricated pan and wall kit, this is a genuine weekend project for a competent DIYer. Demolition, substrate, kit, trim. You will still want the permit if your jurisdiction requires one, but nothing here needs a licensed trade.

If the drain moves, or the line has to be upsized, or you are building a tiled pan, hire it out. Most jurisdictions require a licensed plumber for drain work, waterproofing failures do not announce themselves for two years and then present as a ceiling stain in the room below, and a site-built pan is the single most commonly botched element in residential bathroom work. The money you save on labor here is borrowed against a repair you cannot see coming. Water damage remediation runs $1,500 to $5,000, which wipes out the entire labor saving on the first failure.

One more consideration that rarely gets mentioned: on a manufactured tub or shower base, self-installation can affect the manufacturer's warranty. Read the warranty before the box is opened, not after.

Which Conversion Is Right for Your Bathroom

Two more things change the answer, and neither is about taste.

If you are on a concrete slab, assume the drain relocation is the expensive version. Moving a drain in a slab means cutting concrete, re-running the line, patching and waiting on inspection, and it can add $1,200 to $2,400 on its own. On a slab, the conversion that keeps the drain where it is will always be dramatically cheaper than the one that moves it, and that is worth more than a preference about layout. If you have a crawlspace or a basement below, the same move is routine and the line drops toward $400.

If you are selling within about eighteen months, do the cheaper, safer version and keep a tub in the house. Buyers reward a clean, functional bathroom far more reliably than they reward a specific fixture choice, and a $14,000 curbless build will not return $14,000 in a fast sale. If you are staying five years or more, buy the bathroom you want. The daily use compounds and the resale question stops being the deciding factor.

If you are still weighing the two fixtures rather than the two prices, we have laid out the case for and against each, and the broader shift in how people are using these rooms is covered in our look at why some homeowners are rethinking the standard tub and shower combo.

How to Read a Conversion Quote Before You Sign

You do not need to become an estimator. You need four things in writing.

1. Make every quote itemise the same eleven lines. A quote that gives you one number is a headline, not a scope, and it cannot be compared against anything. Send the ledger above and ask for the same rows back.
2. Get the drain answered explicitly. Ask whether the drain moves, how far, whether the line is being upsized, and whether that price is inside the quote or outside it. This is where change orders come from.
3. Get the rot clause in writing. Ask what happens if the subfloor under the tub is wet, at what hourly rate, with what markup on materials. Agree it before demolition day, not on demolition day.
4. Get three quotes and one of them from a local trade. Franchise pricing and local tile crew pricing are two different markets for the same bathroom. You cannot see the spread until you have both.

Do those four and you will walk into the decision knowing what your bathroom costs rather than what the internet thinks the average bathroom costs. Longer term, you end up with the room you actually use every morning, priced on the work it required rather than on whoever had the biggest advertising budget in your market.

Planning a Bathtub With Badeloft

Whichever direction you are heading, the fixture is the part of this project you will still be looking at in fifteen years, long after the invoice stops stinging. If your ledger has a tub on it, whether you are putting one back after a conversion you regret or specifying one for the first time, the material and the size do more for how the room feels than any other line on the page. Badeloft's freestanding stone resin bathtubs are made to be the thing the room is designed around, in 27 shapes and three finishes, so you can find the one that fits the space you are actually working with.
