Tub-to-Shower Conversion Cost: Complete Pricing Guide for Homeowners

Aug 13
7 min read

Many bathroom remodeling schemes that include pulling out a tub and placing in a shower cost anywhere between $2,000 and $15,000, though the number turns hard depending on what is beneath the tub and what you are requesting the contractor to build in its position. A custom shower outfit that is integrated into an existing step is a very different job than a curbless, tiled walk-in with an unframed glass panel, and the price tag considers that opening. This guide breaks down where the money really goes, what tends to surprise householder mid project, and how to tell whether a quote is acceptable for the range of work explained.

Why the Same "Tub-to-Shower Conversion" Quote Can Vary by $10,000

The largest factor in bathroom remodeling pricing for a transformation is not the size of the bathroom; it is whether the plumbing stops where it is. In accordance with cost data assembled by This Old House, a conventional tub-to-shower transformation usually runs $2,000 to $12,000, with the lower end coating prefabricated pieces and the higher end coating traditional tile and basic changes.

If the exhaust provides lines and the shower tap can stay in around the same place the tub used to be, a contractor is mainly trading with ruining a new pan wall surround and finishing work. That's the cheaper path, and it's also the faster one, often a two- to four-day job for an experienced crew.

Move the drain, add a bench seat that needs its own framing, or discover the subfloor has been absorbing water for a decade behind the tub's caulk line, and the job changes shape entirely. Angi's 2026 pricing data puts full transformations to a walk in shower conversion with conventional tile at $3,500 to $15,000, and that scope continues because "custom tile walk-in" can mean a basic subway tile shower or a floor to ceiling stone installation with a straight drain and a built in recess.

What Bathroom Remodeling Budget Usually Includes

Labor typically eats 40 to 60 percent of the total bathroom remodeling budget on these projects, not materials a detail homeowners shopping by material samples alone tend to underweight. Permits for plumbing and electrical work usually run $200 to $2,000 depending on the municipality, and skipping that step to save money is one of the more common regrets contractors hear about during resale inspections.

Here's how the numbers break down across the three project types most homeowners actually choose between:

Cost Category	Prefab Shower Kit	Tub Cut-Down Conversion	Custom Tile Walk-In
Tub removal & disposal	$150 – $400	$150 – $400	$150 – $400
Shower base/pan	$350 – $1,600 (included in kit)	Minimal existing tub reused	$600 – $2,500 (custom pan)
Wall surround/tile	$500 – $1,500 (kit panels)	N/A	$2,500 – $8,000
Plumbing adjustments	$300 – $900	$200 – $600	$600 – $2,400
Glass doors/enclosure	$400 – $1,200	Not applicable	$800 – $3,000+
Permits	$200 – $800	$200 – $600	$500 – $2,000
Typical total	$1,500 – $6,000	$800 – $1,800	$5,500 – $15,000

When homeowners call around for bathtub conversion pricing, this is usually the option that gets skipped over simply because contractors do not always volunteer it. Many people only hear about the full walk-in and the prefab kit unless they ask directly.

What's Usually Hiding Behind the Tub

Once demolition starts on a bathroom remodeling project like this, a contractor gets the first real look at what's been sitting behind the tub surround for years, and it's rarely nothing. Rotted subfloor from slow leaks, mildewed drywall, and undersized or corroded supply lines are common enough on bathroom conversion cost estimates that experienced remodelers build a contingency line into every proposal rather than treating it as a rare surprise.

Cast iron tubs deserve their own mention. They are heavy enough often 300 to 500 pounds that removal from an upstairs bathroom sometimes requires breaking the tub apart in place rather than carrying it out whole, which adds labor time a ground-floor removal would not need.

Waterproofing and Code Requirements That Affect Long-Term Cost

A properly built shower system uses a waterproof membrane behind the entire wet wall assembly, not just at the pan. Cutting corners here is invisible at handoff and expensive two years later when water starts tracking into the framing.

If the household includes anyone planning to age in place, ADA bathroom remodeling process can include building blocking into the walls for grab bars during the open wall phase of the project, even if a bar is not installed immediately. Increased blockade lets a check be added later without biting into a completed tile, and it costs practically zero to add while the pegs are beforehand uncovered. Standard position guidance calls for take bars to be climbed 33 to 36 inches above the floor with a minimum 1.5-inch approval from the wall, fastened to buttons or stopping rated to manage roughly 250 pounds of force.

Tub-to-Shower Conversion | Step by Step

Site evaluation and plumbing assessment: A contractor checks the drain location the supply line condition, and whether the existing framing can support the new layout without relocation.
Permitting: Most municipalities require a plumbing permit for a conversion, and some require an electrical permit if new lighting or a fan is added.
Demolition: The tub, surround, and any water-damaged material behind it come out — this is also when hidden problems surface.
Rough plumbing: Drain and supply lines are adjusted or replaced to match the new shower layout.
Waterproofing: A membrane system goes over the pan and wet walls before any tile or panel installation begins.
Pan, walls, and finish materials: The shower base is set the wall surround or tile is installed, and the fixtures are mounted.
Glass, hardware, and final inspection: Doors or panels go in last, followed by a plumbing inspection where required.

Mistakes That Turn a Simple Job Into an Expensive One

Skipping the permit to save the fee is the mistake that costs homeowners the most down the line in any bathroom remodeling project, because unpermitted plumbing work routinely surfaces during a home sale and can force a redo under time pressure with a buyer's inspector watching. Hiring based on the lowest bid without asking what waterproofing system is included is a close second two contractors quoting the same square footage can differ by thousands of dollars because one is using a proper membrane system and the other is relying on tile mastic and hope.

What to Consider Before Your Conversion

Your long-term plans for the home A walk in shower conversion with a low or no threshold tends to hold resale value better in markets with an aging buyer pool, and it's a meaningfully safer daily option if anyone in the household has mobility concerns now or expects to in the next decade.
What's actually behind the tub Homes older than 25–30 years should budget a contingency of 10–20% above the initial estimate for subfloor or plumbing surprises that only appear once demolition starts.
Prefab versus tile, honestly assessed Prefab kits install faster and cost less upfront; tile offers more design flexibility and tends to hold up better over 15–20 years if installed correctly, but it depends far more on installer skill for the waterproofing to hold.
Determine if the drain is moving or not. The most expedient way to manage the shower conversion cost is to keep the same location for the shower drain. Moving it involves additional plumbing work and in slab-built houses may even involve breaking the concrete.
Allow & Inspection timelines it can take days to weeks for the municipality to review permits, and asking your contractor for a realistic timeframe that includes permit review time is a good idea – not just labor days.

Common Tub-to-Shower Conversion Questions

Homeowners planning a tub replacement cost comparison as part of a broader bathroom remodeling decision often start by asking how a tub to shower conversion cost stacks up against simply replacing the tub with a new tub. Here's what tends to come up most.

What is the cost of a tub to shower conversion? A simple conversion with a prefabricated kit is a bit more expensive at $1,500 to $6,000 installed, including tub removal, new tub base, shower wall panels and standard fixtures.

Would it be beneficial to convert a tub to a shower for resale? In markets where older buyers or move-down buyers make up a larger percentage of the buyer population, it has always been a key feature that is mentioned by home sellers as a selling point, and in more family-friendly markets, a minimum of one accessible, low-threshold shower in the home is often a desirable characteristic.

Can I convert a tub to a shower without moving the plumbing? Yes, and it's the cheaper, faster option in most cases as long as the existing drain location works with the new shower pan size and the supply lines are in acceptable condition once the wall is opened.

How long does a typical conversion take? A prefab kit conversion usually takes two to four days. A custom tile walk-in with waterproofing, tile setting, and cure time between stages typically runs one to two weeks, not counting permit approval time before work starts.

What's the difference between tub conversions and a full bathroom remodel? A tub-to-shower conversion is scoped to the tub area specifically demo, plumbing, pan, walls, and enclosure. A full remodel typically also touches the vanity, flooring outside the shower, lighting, and ventilation, which is why full shower remodels carry a wider cost range than a conversion alone.

Professional Insights for Homeowners

In bathroom remodeling, the decision that matters most isn't tile brand or glass style — it's whether the plumbing plan and waterproofing system are settled before demolition starts. Homeowners who get a clear answer on drain location, membrane type, and contingency budget upfront tend to have far fewer mid-project surprises than those who select finishes first and figure out the technical plan as the job goes. A contractor who walks through that sequence with you before quoting a number is usually the one worth hiring, regardless of where their bid lands in the range.
