Converting a Tub to a Shower: Does It Hurt Resale Value?

Will taking out the tub actually cost you at resale?

Converting a tub to a shower can hurt resale when it removes the only bathtub in the home, because many family buyers want one. If another bathroom keeps a tub, the risk is generally low. Local buyer expectations decide the rest.

That’s the short version. The rest of this article covers what most “tub vs shower” posts skip: how to tell which side of that line you’re on, and what the swap costs once the old tub is out and the floor is open.

Most homeowners don’t realize the real question isn’t tub versus shower. It’s whether you’re about to remove the last tub in the house, and whether the pipes under that tub will allow what you’ve drawn on paper. The first question tends to come up when an agent mentions it. The second usually comes up mid-demolition, when changing course is expensive.

Quick takeaways

Count your tubs first. One tub elsewhere in the house is the biggest resale safeguard.
A same-footprint swap is often straightforward, but drain position and size decide the real cost.
Slab floors, upper-floor joists and hidden rot are the usual budget-breakers.
Full bath versus three-quarter bath labels vary by region, so confirm with a local agent.
Waterproofing is the one part of a shower build where shortcuts show up years later.
If you may sell soon, get an agent’s view before demolition. This decision is hard to reverse.

The last-tub test: who should convert and who should think twice

Walk through the house and count the bathtubs. That number does most of the work.

If the swap leaves you with none, you’re taking on resale risk. Buyers with babies and toddlers often treat a tub as a requirement, and some will filter their searches for one. If at least one tub remains, a converted bathroom is usually a safe bet. In a primary bathroom it’s often a real upgrade, since a shower is easier to step into and easier to keep clean.

There’s no reliable universal percentage for what a missing tub costs you, and anyone quoting one is guessing. Local sold listings are better evidence. Ask an agent which comparable homes with and without tubs sold nearby, and how quickly.

Convert	Think twice
Another tub remains in the house	This is the only tub in the house
You’re staying for years	You may sell within a few years
Someone in the household struggles with the step-over	Your likely buyers are families with young children
The tub hasn’t been used in ages	The property is a rental aimed at families

US and Canada: A bathroom with a toilet, sink and shower but no tub is typically called a three-quarter bath. Whether that changes the official bathroom count varies by market and appraiser, so confirm locally.UK: Terraces and smaller homes often have just one bathroom, so losing the only bath matters more than losing one of several. Listings may call the result a “shower room”.Australia: Shower-only bathrooms are common in apartments, so buyers there are used to them. A family house with a single bath is a different conversation, so ask a local agent.

What changes under the floor and inside the walls

On paper, a 60-inch tub and a 60-inch shower base look like a clean swap. They aren’t, because the tub drains at one end while many shower bases expect the drain somewhere else. Shower drains are also commonly specified larger than tub drains. So the plumber’s first job is working out what happens at the trap.

Four things decide how hard that is:

Floor type. On a timber floor with access from below (a basement ceiling or crawlspace), moving a drain mostly comes down to joist direction and pipe run length. Joists can’t be notched freely, and limits vary by code, so verify locally. On a concrete slab, moving a drain means cutting concrete, which is a different class of job.
Wet wall contents. Valve height, supply lines, vents and sometimes wiring all sit in that wall. Nobody should open it without knowing what’s inside.
Hidden damage. Tubs hide slow leaks well. Subfloor rot often shows up only once the tub is out.
Hot water (especially in the UK). A tub tolerates weak flow because you wait for it to fill. A shower doesn’t. Whether you have a combi, tank-fed or unvented system changes how the new shower will actually feel, so check pressure and flow before you commit.

Change type	Rating	What decides it	Who does it	Cost direction
Same alcove, drain at same end, prefab base	Easy to moderate	Drain alignment and size, subfloor condition	Plumber or qualified contractor	Lowest
Same footprint, custom tiled base	Moderate	Waterproofing skill, curb detailing	Tiler plus plumber (licensed waterproofer where required)	Mid
Drain moved to centre of larger base, timber floor with access	Moderate to hard	Joist direction, notching limits, pipe run length	Plumber, possibly a builder	Mid to high
Drain moved through a concrete slab	Hard	Slab cutting, repiping, reinstatement	Plumber plus concrete cutter	High
Shower enlarged into a closet or neighbouring wall	Hard	Wall contents, framing, wet wall	Builder plus plumber	High
Load-bearing wall altered or soil stack relocated	Structural	Structure and stack position	Structural engineer plus licensed trades	Highest

Ratings are general guidance. Verify with your local building authority and a qualified professional.

What happens to the budget once the old tub is out

Most quotes look reasonable until demolition day. That’s when the line items nobody could see (rotted subfloor, a drain in the wrong spot) get added.

The table below breaks the job into lines so you can see where the swing comes from. These are estimated ranges in USD for planning, not quotes.

Line item	Low	Typical	High	Main variance driver
Demolition, tub removal, disposal	$300	$600	$1,200	Cast iron vs acrylic tub, stairs, disposal fees
Shower base	$250	$700	$2,500	Prefab vs custom mortar bed
Drain and plumbing adjustment	$300	$1,000	$4,500+	Slab vs timber, pipe run length, access
Shower valve and trim	$200	$500	$1,500	Valve type, wall access
Walls and waterproofing	$800	$2,500	$6,000	Prefab surround vs tile, membrane system, labour rates
Subfloor or framing repair	$0	$400	$2,500	Hidden rot found at demolition
Door or curtain	$50	$400	$2,000	Curtain vs frameless glass
Permit and inspection	$0	$150	$600	Jurisdiction, and whether plumbing changes
Estimated total	~$1,900	~$6,250	~$20,800+	All the highs rarely coincide

The cheapest version of this job keeps the drain roughly where it is and uses a prefab surround. The most expensive is a tiled shower with a drain relocated through concrete. Same room, same “tub to shower” label, wildly different invoice.

A quote near the top of that range usually means a slab drain move, rot, or both. If a quote comes in far below the typical column, ask what it leaves out.

UK, Canada and Australia: Once converted to local currency, costs broadly land in a similar range. Labour rates, city and access move the number more than the exchange rate does. Check whether quotes include VAT (UK), GST/HST (Canada) or GST (Australia).

Budget a 10-20% contingency for hidden conditions. If a contractor’s quote has none, that’s worth a question.

Before you book anyone: check these in your own house

A handy DIYer can usually handle demolition and fitting a prefab surround. The drain, trap and waterproofing are where mistakes hide for years, and many regions require licensed trades for them. Do the homework below first, so any quote you get is based on what’s actually in your walls and floor.

Two cheap tools earn their keep here. A pin-style moisture meter and a flashlight will tell you more about the ceiling or crawlspace under the tub than guessing will. After the job, a battery-powered leak sensor near the shower is a low-cost safeguard.

If you’re adding a new fan, light or heated mirror in the shower area, that’s an electrician’s job. Zone and GFCI/RCD requirements differ by country, so verify locally.

⚠️ Warning: A 60-inch tub and a 60-inch shower base look like a perfect swap, but the drain is rarely in the right place. Confirm drain position and size with a plumber before ordering the base.⚠️ Warning: Don’t remove the last tub in your house on the strength of a general article, including this one. Ask a local agent for recent sold listings first, because demolition is the point of no return.⚠️ Warning: A tub’s rim doubles as a waterproof barrier. A shower needs a continuous, correctly detailed membrane, and shortcuts here tend to fail slowly and invisibly. Use a licensed or qualified installer where your region requires it.

Middle paths if you’re not ready to lose the tub

The choice isn’t always tub or shower. Three options sit in between.

Keep a tub somewhere else. If a second bathroom or a hall bath still has one, convert the primary bathroom and leave the tub where family buyers will look for it.
Install a tub-shower combo with a lower step-in. You keep the tub for resale and kids, and the shower gets used daily. The step-over remains, so this won’t suit anyone with mobility concerns.
Convert the secondary bathroom only. It’s often the lower-risk place to experiment, and you can see how the shower works in daily life before touching your main bathroom.

If you’re leaning towards a larger walk-in design, plan for the plumbing and waterproofing work in the cost table above, since enlarging a shower is where budgets usually stretch. A standard prefab base in the old tub’s footprint also tends to be easier to reverse later than a custom tiled one, though nothing about demolition is truly cheap to undo.

Keep, convert, or split the difference: a quick decision guide

Find the line that sounds like your house.

If this is the only tub in the house and you may sell within a few years, keep the tub or talk to a local agent before converting.
If another bathroom has a tub, converting the primary bathroom is generally low-risk.
If you’re ageing in place or have mobility concerns, a low-threshold shower is usually worth more to you than to hypothetical buyers.
If you have a concrete slab and want the drain moved, get a plumber’s quote before committing to the layout.
If the drain can stay roughly where it is, a same-footprint swap is usually the cost-efficient route.
If you’re a landlord or investor, check local tenant and buyer expectations before removing a tub.
If you have young kids, a tub-shower combo or a tub kept elsewhere is the safer choice.
If your quote includes no contingency, ask for one. Subfloor surprises are common.

Questions homeowners ask before swapping a tub for a shower

Does converting a tub to a shower lower my home’s value?

It depends on what you remove and who buys in your area. Taking out the only tub is the situation agents most often warn about, because buyers with young children usually want one. If another bathroom keeps a tub, a well-built shower is generally a low-risk change, especially in a primary bathroom. There’s no universal percentage, so ask a local agent to show recent sold listings before you commit.

Does it turn a full bath into a three-quarter bath?

In US and Canadian listing language, usually yes. A bathroom with a toilet, sink and shower but no tub is typically called a three-quarter bath. Whether that changes the official bathroom count or an appraisal varies by market and appraiser, so confirm locally. UK and Australian listings are less formal, but “bathroom” versus “shower room” can signal whether a bath exists.

Can I convert without moving the plumbing?

Sometimes. In a US or Canadian alcove, tubs are commonly 60 inches long and prefab shower bases come in that length, but the tub drain sits at one end while many bases expect it elsewhere. Shower drains are also commonly specified larger than tub drains. Expect a plumber to adjust the drain and trap at minimum. Slab floors make relocation much costlier. Verify requirements with your local building authority.

Do I need a permit?

Often yes if you alter drain or supply lines, and sometimes even for like-for-like work, depending on where you live. Rules differ across US jurisdictions, UK Building Regulations, Canadian provincial codes and Australian state rules. Licensed trades are commonly required for plumbing and waterproofing. Unpermitted work can surface during a sale or an insurance claim, so check with your local building authority first.

Is it worth converting if I’m staying for years or ageing in place?

Often yes. If you’re living in the house, daily comfort and safety matter more than hypothetical buyers. Stepping over a tub wall is a real hazard for some people, and a low-threshold shower is easier to use. If you may sell later, choose a design that suits future buyers and keep a tub elsewhere if you can.
