Key Takeaways
- Conversion pricing is driven by the existing conditions, wall system, entry, glass, fixtures, plumbing work, and selected safety features.
- A same-footprint conversion — shower where the tub was — is the most cost-efficient version of this project.
- The tub removal itself is rarely the expensive part; what is behind the tub often is.
- Converting a rarely-used guest or hall tub is one of the highest-satisfaction remodels homeowners report.
- Keeping at least one bathtub in the home is the usual advice for resale. If you have two baths, converting one is a safe move.
- Cast iron tubs cost more to remove than steel or fiberglass — they often have to be broken up in place.
What a tub-to-shower conversion costs
A tub-to-shower conversion includes complete tub removal and installation of a new shower system. The quote must account for the exposed conditions, new base, custom walls, drain, valves, supply lines, fixtures, glass or open entry, and selected safety features.
| Scope decision | What changes | Why it matters |
|---|---|---|
| Entry and base | Standard, low, or zero barrier where the home permits | Changes access and preparation requirements |
| Glass or open entry | Door style, usable opening, and splash control | Affects both function and material scope |
| Safety and storage | Backing, grab bars, seating, handheld washing, shelving | Should be planned before installation |
Compare that to the 2025 national average bathroom remodel of over $25,000. A conversion delivers the single most noticeable change in the room — you walk into a shower instead of stepping over a wall — for meaningfully less.
The five things that move the price
1. Whether the drain and valve stay put
Tub and shower drain locations can differ. Patriot Showers installs a new drain and determines how the new shower connects to the home’s plumbing after the existing system is removed and the conditions are visible.
2. What is behind the tub
Older alcove tubs, especially in homes built before 2000, frequently hide water damage at the wall-to-tub joint. Rotted studs or a soft subfloor must be repaired before a new base goes in. Ask any contractor in advance how they price repairs they discover mid-install and whether they document it with photos.
3. What the tub is made of
A steel or fiberglass tub comes out in one piece with two people and a dolly. A cast iron tub can weigh 300 to 500 pounds and usually has to be broken up in place — more labor, more debris, more protection for the floors on the way out. It is not a huge line item, but it is a real one, and it is why an experienced estimator asks what your tub is made of before quoting.
4. Wall material
The same rule applies here as anywhere in a bathroom: material is the biggest line item and the biggest long-term difference. Non-porous 100% virgin acrylic carries a limited lifetime warranty and needs no sealing. Tile costs more, takes weeks, and its grout is a maintenance item forever. Details: acrylic vs. tile.
5. Entry height and safety features
A low-threshold entry is the whole point of the conversion for many homeowners — a standard tub wall is roughly 15–16 inches to step over, which is the exact motion that causes falls. Low-threshold bases, fold-down bench seating, grab bars, and slip-resistant floors add modest cost and enormous day-to-day value. See our aging-in-place bathroom guide.

Should you convert your tub?
The honest answer depends on how many bathrooms you have and who uses them. Here is the framework we walk homeowners through — including the cases where we tell people not to convert.
| Your situation | Recommendation |
|---|---|
| One bathroom, no young children, mobility is a concern | Convert. Safe daily access outweighs a tub you rarely use. |
| Two or more bathrooms, one tub sits unused | Convert the unused one. You keep a tub in the home for resale and still gain a walk-in shower. |
| One bathroom, young children in the home | Consider a tub and shower replacement instead — new surfaces and fixtures, tub configuration kept. |
| Primary suite tub used a few times a year | Convert. This is the most common and most satisfying version of this project. |
| Only tub in the home and you plan to sell within a year | Keep one tub. Most agents advise a home retain at least one bathtub. |
The resale question, answered directly
The concern homeowners raise most often is whether removing a bathtub hurts the value of the house. The honest answer has two parts. Removing the only tub in a home narrows your buyer pool — families with small children genuinely want one, and some buyers will filter listings on it. Removing one of two or more tubs does not, and frequently helps, because walk-in showers are among the features today’s buyers most want in a primary bathroom.
If your home has two full baths and one tub goes years without being filled, that tub is not protecting your resale value. It is occupying the square footage where a shower you would actually use could go. More on how these projects perform at resale: bathroom remodel ROI.
How long a conversion takes
With a custom-measured acrylic system, most conversions are completed in as little as one day. The walls and base are manufactured to your bathroom’s exact dimensions ahead of install day, so nothing is cut to fit on your floor and there is no cure time to wait out.
A tile conversion is a different project entirely: demolition, plumbing rough-in, waterproofing, setting, grouting, curing, sealing, then glass — three to six weeks with multiple trades to coordinate, and a bathroom you cannot use for most of it.
Is a DIY tub-to-shower conversion worth it?
It is a fair question, and the answer is not simply “no.” It is that the savings are smaller than they look and the downside is worse than it looks.
The demolition is genuinely doable for a capable homeowner. What follows is where it gets difficult: adapting the drain correctly, setting a base dead level so water actually reaches the drain, waterproofing the wet area properly, and getting panels or tile plumb in a room where almost nothing is square. A shower that leaks slowly does not announce itself — it announces itself three years later as rotted framing.
The other consideration is warranty. Manufacturer warranties on wall systems generally require certified installation. A DIY install typically means the surface is on your own — which removes the single biggest financial advantage of choosing a lifetime-warranted material in the first place.
What should be included in your quote
A complete written quote should account for every one of these. If a line is missing, it will show up later as a change order.
- Tub removal and haul-away of all debris, including cast iron breakdown if applicable
- Substrate inspection and any needed wall or subfloor repair
- Drain adaptation and valve work
- Custom-measured shower base with slip-resistant surface
- Full-height acrylic wall surround in your chosen pattern
- Glass door or enclosure
- New fixtures, showerhead, and hardware in your chosen finish
- Accessories — shelving, niches, corner caddies, grab bars, seating
- Final cleanup and a walkthrough before the crew leaves
- Written warranty documentation

Frequently Asked Questions
How much does it cost to convert a tub to a shower?
Price depends on the existing wet area, preparation, base and entry, custom wall system, plumbing connections, glass, fixtures, seating, and accessories. Patriot Showers provides an exact written price after measuring the bathroom and confirming selections during the free in-home consultation.
Is converting a tub to a shower worth it?
For most households, yes. Bathtubs in secondary bathrooms often go years without use, while a walk-in shower is used every day and removes the roughly 16-inch step-over that causes many household falls. If the home has only one bathtub and you plan to sell soon, most agents recommend keeping one tub in the home.
Does removing a bathtub hurt resale value?
Removing the only bathtub in a home can narrow the buyer pool, particularly with families who have young children. Converting one of two or more tubs generally does not hurt value and often helps, because walk-in showers are among the most requested features by today’s buyers.
Does a tub-to-shower conversion require moving plumbing?
The drain, valves, and supply lines are replaced as part of the new system. Whether the home requires additional plumbing preparation can be confirmed only after the existing wet area is evaluated and removed.
How much does it cost to remove a cast iron tub?
Cast iron tubs weigh roughly 300 to 500 pounds and usually have to be broken up in place rather than carried out whole, which adds labor, debris handling, and floor protection to the job. It is a modest line item rather than a major one, but it is why an experienced estimator asks what your tub is made of before pricing the work.
How long does a tub-to-shower conversion take?
Most conversions using custom-measured BathWraps acrylic are completed in as little as one day. If structural or plumbing issues turn up once the tub is out, the timeline can extend slightly. A tile conversion typically takes three to six weeks across multiple trades.
Can a converted shower still have a seat?
Yes. Fold-down bench seating and built-in corner seats are both available, along with grab bars in decorative finishes, handheld shower heads, and slip-resistant bases. They are designed to look like intentional design choices, not medical equipment.
