Tub-to-Shower Conversion in Greater Cincinnati: What’s Involved and What It Costs

We’ve been converting old tubs into showers around Cincinnati long enough to know the question behind the question. When someone in Montgomery or Hyde Park calls us about pulling out a tub, they’re rarely just chasing a new look. They’re thinking about stepping over a wet tub wall at 72, or a knee that doesn’t bend the way it used to, or a guest bath nobody uses because getting in and out is a chore. That’s the real job. Here’s how we approach it, what it actually takes, and what you should expect to invest.

What a Tub-to-Shower Conversion Really Is (and Why We Rebuild)

A tub-to-shower conversion means removing your existing bathtub and building a walk-in shower in its place. Simple in concept. The part that separates a shower that lasts 25 years from one that leaks in three is what happens behind the tile.

Plenty of companies will sell you an overlay: an acrylic liner or a prefab surround snapped over the old surface in a day. We don’t do that, and here’s why. When we strip a bathroom to the studs, we find things. Soft subfloor under the old tub. Mildew where water wicked into framing years ago. A shower floor that was never framed to carry weight the way it should. You can’t fix any of that with a panel glued over the top. So when we take on a conversion, it’s a from-scratch rebuild, done with correct building science on every layer.

That’s the same approach we took on a recent primary bath here on the east side. The homeowner had a freestanding Jacuzzi tub she never used and a shower that felt cramped. We moved a wall to make the shower much larger, tore everything back to framing, ran all-new plumbing, and built a zero-degree curbless entry shower with all-new tile, a new vanity, quartz countertops, and fresh lighting. It’s the kind of transformation you simply can’t get by covering up what’s already failing.

Is It a Good Idea to Convert a Tub to a Shower?

For most homeowners staying in their house long-term, yes, it’s one of the smartest bathroom decisions you can make. Here’s who it fits and who it doesn’t.

It’s a great move if you:

• Have a tub you never soak in but step over every single day
• Are thinking ahead about aging in place and want to stay in the home you love
• Want a bigger, brighter, easier-to-clean bathroom
• Have mobility concerns, or want to get ahead of them before they arrive

Two honest cautions. First, if you have young kids, keep at least one bathtub in the house. Second, if you’re selling within six months or renting the place out, this probably isn’t the project for you. Our clients are people who love their home and want to love it more, not folks flipping a property. If you’re staying put, an accessible walk-in shower adds real day-to-day value and appeal.

Aging-in-Place Features Buyers Ask Us For

Demand for this has climbed steadily. Most of our conversion clients are near or past retirement and want the bathroom to work for the next 20 years, not just look good today. The aging-in-place bathroom features we build most often:

• Zero-degree curbless entry so there’s nothing to step over and a walker or wheelchair rolls right in
• Grab bars blocked into the framing during the rebuild, not screwed into tile afterward, so they hold real weight
• A built-in bench or seat for a seated shower
• Slip-resistant floor tile and a handheld fixture on a slide bar
• A wider doorway where the layout allows

Can I Convert My Old Bathtub to a Shower?

In almost every case, yes, though the specifics depend on your layout, plumbing, and what’s under the tub. We don’t know for sure until we open it up, which is exactly why we plan the whole thing before we swing a hammer.

The one detail people underestimate: a zero-degree curbless entry shower needs the drain and floor slope handled during framing, which sometimes means recessing the subfloor. It’s very doable. It’s just not something you decide on the fly. We work all of that out at the design stage so there are no surprises mid-project.

How the Conversion Process Works

Our kitchens and baths are 100% in-house, our own crews, not a rotating cast of subs. Once we start, we’re on your job Monday through Friday, 8:30 to 5, until it’s done. No waiting on another trade, no waiting on materials, because we selected everything with you months in advance. A conversion typically runs about four weeks start to finish.

Design and 3D Rendering First

We won’t hand anyone an estimate scribbled on a napkin. Before you sign anything, you’ll see a 3D rendering of your finished shower. Our designer, Carlie, helps you choose tile, fixtures, and finishes, and instead of limiting you to a showroom shelf we’ll take you around the city to find exactly what you want. In-person consultations are always free.

Demo and Prep (This Is Where the Real Work Hides)

We protect your home and contain the dust, then strip the space to the studs and remove the tub. We fix any mold or mildew, strengthen the shower floor and framing, and get the drain and slope right. This prep phase runs a week to 10 days before a single piece of tile goes up. Most homeowners are surprised how much happens here.

Waterproofing With Wedi

This is the layer that decides whether your shower lasts. We waterproof with concrete board or a system like Wedi®, a bonded barrier that keeps water out of your framing for good. Waterproofing a shower with Wedi is precise work, and it’s the step overlay companies skip entirely. On a heated floor we set the mat over concrete board before tile.

Tile, Finishes, and Final Walkthrough

Tile goes in, then the vanity is set, followed by electrical, exhaust, mirror, and lighting, and finally drywall and paint. We vacuum and dust at the end of every day, so you’re never stepping over tools. When we finish, we walk the whole bathroom with you. Every client tells us we’re the cleanest contractors who’ve been in their home, and we take that seriously.

What a Tub-to-Shower Conversion Costs in Cincinnati

We’ll always agree that this stuff is expensive. It’s expensive to fill your gas tank and expensive at the grocery store, and getting something custom at the highest quality costs too. Here’s the honest range so you can plan.

A straightforward bathroom refresh runs $20,000 to $40,000. A complete primary bathroom rebuild, which is what most conversions with a curbless shower become, lands in the $50,000 to $70,000 band, with high-end work at $70,000 and up. Most master baths we do fall between $40,000 and $80,000, and more of them push past 80 than sit near 40.

What Moves the Number

• Changing the footprint (moving walls or relocating plumbing) is the single biggest driver
• Zero-degree curbless entry, because of the framing and drainage work involved
• Heated floors
• Tile and fixture selections, which range widely

We build allowances into the proposal so the cost stays predictable and shouldn’t escalate mid-project. We’re not the most expensive guys in town, and we’re not the cheapest. We pay our craftsmen well because our clients want experienced people in their home. We don’t have a fancy showroom, we put the investment into the team and the materials. When we lose a bid to someone cheaper, we often get a call later saying it definitely wasn’t TMC quality.

Can a Plumber Do a Tub-to-Shower Conversion?

A plumber can move the drain and water lines, but a proper conversion is a full remodel that involves framing, waterproofing, tile, electrical, and finish carpentry, so it needs a design-build remodeler coordinating all of it. That’s the gap where DIY kits and single-trade jobs get people in trouble. The waterproofing and the shower-floor framing are where leaks start, and those aren’t plumbing tasks. We handle every trade in-house on baths, plus all HOA plans, county approvals, and inspections.

Frequently Asked Questions

How much does it cost to convert a bathtub to a shower?

Most tub-to-shower conversions in the Cincinnati area run between $50,000 and $70,000 when done as a full rebuild with a curbless shower, while a simpler refresh can land in the $20,000 to $40,000 range. Your final number depends on whether you move walls, add heated floors, and the tile and fixtures you choose. We give a firm price with a 3D rendering before you sign.

How long does a tub-to-shower conversion take?

Plan on about four weeks from demo to done. We’re on your job every weekday until it’s finished, with about a week to 10 days of prep and waterproofing before tile goes up. We don’t run 15 jobs at once, so your bathroom stays the focus until it’s complete.

Do I need a permit for a tub-to-shower conversion?

Often yes, especially when plumbing moves or the layout changes, and we handle all of it for you. That includes HOA preliminary plans, county plan approval, and inspections, so nothing lands on your plate.

How do I keep a new tile shower easy to maintain?

Choosing larger-format tile with fewer grout lines and a quality sealed grout makes upkeep far simpler, and a properly waterproofed base means no hidden moisture problems down the road. We build with correct building science so the shower stays sound for the years you live there.
