Tub to Shower Conversion Cost: A 2026 Central Ohio Guide

Converting a bathtub to a shower is one of the highest-value bathroom updates a homeowner can make, whether the goal is a more modern look, easier daily use, or planning ahead for long-term accessibility. It’s also a project with a genuinely wide price range, because “tub to shower conversion” can mean anything from a same-day prefab kit swap to a full custom tile build with a curbless entry. This guide breaks down what drives that range so you can figure out where your project actually falls.

The short answer

In the current 2026 market, a prefab or kit shower conversion, replacing a tub with a manufactured acrylic or fiberglass shower stall, generally runs about $1,000 to $8,000 installed. A custom tiled walk-in shower runs meaningfully higher, roughly $3,500 to $15,000, reflecting the labor and material intensity of tile work. A walk-in or curbless accessible conversion, designed for easier entry and long-term use, averages around $2,000 to $12,000 depending on finish level and how much the entry threshold and plumbing need to change. These are general 2026 market figures for context, not a Transit & Flow Group quote; your price depends on your bathroom’s specific layout and the finish level you choose, confirmed through a design consultation.

What actually drives the price

Prefab versus custom tile

This is the single biggest fork in the road. A prefab shower stall (acrylic or fiberglass, sometimes called a “shower kit”) is manufactured as one or a few large pieces, which makes installation faster and more predictable, and it’s the reason prefab conversions can be completed in as little as a day in straightforward cases. A custom tiled shower is built in place, tile by tile, with a waterproofed pan and walls, which takes considerably more labor but delivers a fully custom look, size, and design that a prefab kit can’t match. Neither is “wrong,” they serve different priorities: speed and budget versus a fully custom, higher-end result.

Plumbing changes

A standard bathtub uses a 1½ inch drain line; a shower requires a 2 inch drain line, so most conversions involve at least some drain modification. If the shower is going in the exact footprint of the tub with the drain in a compatible location, this is a relatively contained job. If you’re relocating the drain, moving the shower valve, or changing the layout significantly, plumbing labor (commonly $45 to $150 per hour for this kind of work) adds up faster. This is the part of the project that varies most based on your existing plumbing, and it’s why a design consultation looks at your actual bathroom before pricing.

Glass enclosure or curtain

A shower needs some kind of water containment: a curtain (the least expensive option), a framed glass enclosure, or a frameless glass enclosure (the most expensive, and the most common choice in a higher-end remodel). Framed and frameless glass options generally run in the range of $400 to $1,900 depending on size and style, and this single choice can meaningfully shift your total project cost.

Accessibility features

If part of the goal is long-term ease of use, a curbless or low-threshold entry, grab bars, a built-in bench, and a handheld shower head are the features that make the biggest functional difference. Grab bars are a comparatively small cost add (roughly $25 to $370 depending on style and installation complexity), while a fully curbless entry can require more substantial changes to the floor structure and drain location, which is a bigger scope decision to make early rather than adding later.

Wall and floor finish

Beyond the shower enclosure itself, what happens to the surrounding walls and floor affects both look and cost. A full-height tile wall costs more than a partial tile surround with a painted or simpler finish above it. Flooring changes, especially if the bathroom floor needs to be reworked to accommodate a curbless entry, add their own labor and material cost.

General 2026 market ranges, in context

We do not publish a firm final price online, because the right number for your bathroom depends on your existing layout, the finish level you want, and what a design consultation finds once someone can actually see the space. What we do is walk you through the Good/Better/Best options for your specific bathroom so you can see how each choice affects the total.

Materials at a glance

Tub or shower: how to decide

Converting isn’t automatically the right call for every household. A few questions help clarify it.

Do you (or anyone in the household) regularly use the tub for bathing, especially young children? If so, keeping at least one tub in the home, even if it’s not this bathroom, is worth considering before converting your only one. Is stepping over a tub wall becoming difficult, or are you planning for long-term accessibility? That’s the strongest case for converting, particularly toward a curbless design. Are you renovating primarily for resale? Buyer preferences vary by market and price point; a primary bathroom often benefits from keeping at least one tub in the home if there’s only one bathroom, while a secondary or guest bathroom converting to a shower is a common and well-received update. And is the existing tub in poor condition, cracked, worn, or simply dated? If it needs replacing anyway, that’s a natural moment to decide between a new tub and a shower conversion rather than replacing like for like by default.

The Central Ohio factor

A few regional realities shape this project locally. Central Ohio’s hard water affects glass enclosures and fixtures over time, so a frameless glass choice benefits from an easy-clean coating and a maintenance routine, something worth discussing during design. Older Central Ohio homes, especially in neighborhoods like Bexley, Clintonville, and Upper Arlington, often have original plumbing and layouts that make drain relocation more involved than in newer construction, which is part of why an in-person assessment matters more here than a generic online calculator can capture. And homes built before 1978 may fall under EPA RRP lead-safe work practice requirements if the renovation disturbs painted surfaces, which our team follows where applicable.

What’s included in a typical conversion, step by step

Understanding what actually happens during a conversion helps explain where the cost comes from. The process starts with demolition: removing the existing tub, surround, and any trim, and disposing of the old materials. Next comes any plumbing work, adjusting the drain location and size if needed, relocating or replacing the shower valve, and running any new supply lines the design calls for; this step is inspected before anything is closed up if a permit applies. Waterproofing comes next, and it’s the step that most affects long-term durability regardless of finish level: a properly waterproofed pan and wall system (using a modern waterproof membrane rather than relying on tile and grout alone) is what prevents water intrusion into the wall cavity and subfloor over the life of the shower. Then the enclosure itself goes in, whether that’s a prefab acrylic unit installed as one or a few pieces, or tile set piece by piece over the waterproofed substrate. Glass or a curtain rod goes in last, along with any accessibility features, grab bars, a built-in bench, a handheld wand, and final trim and caulking. A prefab conversion can move through this sequence in a single day in a straightforward case; a custom tile build with a curbless entry typically runs several days to two weeks depending on complexity and whether plumbing relocation is involved.

Before and after: what changes beyond the fixture

A conversion changes more than just the fixture itself, and it’s worth setting expectations on what else shifts. Bathroom footprint often opens up visually even when the physical floor space doesn’t change, since a curbless or low-profile shower reads as more open than a tub’s solid wall ever did. Cleaning changes too: a well-sealed tile shower or a quality acrylic unit is generally easier to maintain than an aging tub-and-surround combination, particularly one with worn caulk lines or a fiberglass surround that’s started to show wear. Resale presentation often improves in secondary bathrooms specifically, since a modern shower reads as an update to buyers even in homes where the primary bathroom keeps its tub. And for households converting specifically for accessibility, the functional change, being able to enter and use the bathroom safely without the tub wall, is often the single biggest quality-of-life improvement in the entire renovation, which is part of why this conversion consistently ranks among the highest-value updates a homeowner can make relative to its cost.

Financing and timing considerations

Because the price range for this project is wide, it’s worth thinking through financing and timing before committing to a finish level. Many homeowners find that once demolition begins, whatever hidden issues exist behind the old tub surround, water damage, subfloor softening, outdated plumbing, become visible for the first time, which is why we build a contingency conversation into every estimate rather than treating the initial quote as guaranteed to be the final number regardless of what’s found. On timing, scheduling a design consultation before you have an urgent need (a failed tub, a fall risk that’s already occurred) gives you more room to compare Good/Better/Best options thoughtfully rather than making a rushed decision under pressure. If accessibility is the driver, earlier is generally better than later, both because retrofitting a curbless entry later, after other bathroom work is done, often costs more than building it in from the start, and because planning ahead of an urgent mobility need tends to produce a better outcome than reacting to one.

Permits and process

Bathroom plumbing work, including drain relocation, may require a permit and inspection depending on your municipality; requirements and processes vary across Columbus and the surrounding cities and townships. Permits and inspections may be required for your project, and our team handles that paperwork as part of the job.

Common mistakes homeowners make with this project

A few missteps show up often enough to be worth flagging directly. Choosing the enclosure finish before confirming the plumbing scope is a common one; a homeowner falls in love with a specific frameless glass configuration or tile pattern before anyone has confirmed whether the drain needs to move, and then the plumbing reality forces a redesign mid-decision. Underestimating waterproofing is another: a lower up-front bid that skips a proper waterproof membrane system in favor of tile-and-grout-only construction can look identical on installation day and fail years later with hidden water damage inside the wall, which costs far more to fix than the difference in the original bid. Assuming a curbless entry is a simple swap is a third: converting to a true barrier-free shower often requires lowering or modifying the subfloor to create the necessary slope to the drain without a curb, which is a bigger structural conversation than a same-footprint prefab swap and should be scoped as such from the start rather than discovered midway through demolition. And treating this as a project to price shop purely on the lowest number is a mistake specific to bathrooms: because so much of what determines long-term performance, waterproofing quality, plumbing workmanship, is invisible once the finish goes on, the lowest bid and the best value are not reliably the same thing here, and it’s worth asking any contractor directly what waterproofing system and method they use before comparing price alone.

Frequently asked questions

How long does a tub-to-shower conversion take?
A prefab conversion in a straightforward layout can be completed in as little as a day. A custom tiled shower, especially one involving plumbing relocation or a curbless entry, typically takes several days to a couple of weeks depending on scope.

Is a curbless (barrier-free) shower more expensive?
Generally yes, since it often requires more substantial floor and drain work to eliminate the entry threshold. It’s a worthwhile investment for long-term accessibility, and it’s easiest to plan for at the start of a renovation rather than retrofitting later.

Will converting my only tub hurt my home’s resale value?
It depends on your market and the number of bathrooms in the home. If it’s your only bathroom, many buyers, especially families, still value having at least one tub somewhere in the house. A secondary bathroom converting to a shower is generally a well-received update. Our design team can talk through your specific situation.

Do I need a permit for this project?
Permits and inspections may be required and vary by municipality across Central Ohio, particularly for plumbing modifications. Our team pulls the permit and schedules any required inspection as part of the job.

What warranty comes with a shower conversion?
All workmanship is backed by a 1-year labor warranty on labor, parts, and equipment covered per manufacturer terms..
