Tub-to-Shower Conversion in Tampa Bay

By Ricky Powers · Published 30 June 2026 · Updated 7 August 2026

You step over the tub wall every morning, you never take a bath, and you're tired of cleaning a thing nobody uses. That's the call I get most. Somebody finally wants the tub gone and a real walk-in shower in its place. It's one of the best changes you can make to a bathroom. It's also more work than it looks in the after photo, and I'd rather you knew that going in.

Here's what's actually in the swap.

Why do people swap a tub for a shower?

Most folks have a reason that's plain and practical. They want a bigger, easier shower. The knees aren't what they were and stepping over a tub wall is getting old. The kids are grown and the family tub sits dry. Or the old tub-and-surround insert is cracked and stained and no amount of scrubbing brings it back.

All good reasons. A walk-in shower opens the room up, it's easier to clean, and it's safer to get in and out of. If you're thinking ahead to staying in this house a long time, see aging-in-place bathroom remodels for how to do that without it looking like a hospital.

What work does the after photo hide?

The finished shower is the easy part to picture. It's everything before the tile that earns the number.

Demo and what's underneath. The old tub and surround come out, and that's when the bathroom tells the truth. In a lot of older Tampa Bay homes, there's water damage behind that tub wall that's been quietly sitting there for years. Rotten subfloor, soft framing, sometimes a little mold. Nobody knows for sure until it's open.

Plumbing, and it drives the cost more than the tile does. Worth understanding before you read a single bid, because it is the line item the bids will disagree on. A tub drain and a shower drain are not in the same spot. The tub drains at one end. A shower drain usually sits center or wherever the new layout puts it. So there's drain line work under the floor, and the valve in the wall often gets moved up and changed out too, because a shower wants a different height and sometimes a different valve than the old tub spout did.

Framing. Once the tub's out, the opening gets framed for the new shower. If you want it bigger than the old tub footprint, that's a wall coming in or going. If you want a bench or a niche, those get framed in now, not stuck on later.

Waterproofing. This is the part I won't bend on, so it gets its own section below.

Tile and glass. The visible work. Slow, skilled, and the part you'll look at every day.

Curbless, or with a curb?

A lot of people ask about a curbless shower, where there's no lip to step over and the floor runs flat right into the shower. It looks clean and it's the easiest kind to walk into. But it's more work to build. The shower floor has to be recessed below the bathroom floor so the water still runs to the drain and doesn't head out into the room. That usually means cutting into the subfloor and dropping the framing. On a slab it's a different job again.

Curbless is worth it for a lot of people, especially if anyone in the house has trouble stepping over a curb. It just isn't free, and I'll tell you straight whether your floor can take it without a fight.

Which glass should you choose?

A frameless glass enclosure makes the room look twice as open, and people love it. It's also a real line on the budget. Frameless glass is thick, custom-cut to your opening, and it surprises folks when they see the price. A framed enclosure costs less and does the same job of keeping water in. There's also the option of a walk-in with a single fixed panel and no door at all, if the shower's deep enough. Each one's a real choice. None of them is wrong.

Keep one tub in the house

Here's the against-my-interest advice. If the bathroom you're converting is the only one in the house with a tub, think twice before you pull it. When you go to sell, a house with zero bathtubs turns off buyers with little kids, every single time. A bathtub is where you bathe a toddler. So if you've got a primary bath and a guest bath, converting the primary to a big walk-in shower and leaving the guest tub alone is usually the smart play. If you've only got one bath, we'll talk it through before you commit.

What drives the cost?

Same idea as any bath: the spread is wide because the jobs are different.

Two versions of this job, and they're not close:

• A straightforward swap. Same footprint, framed glass, standard tile.
• A larger or curbless shower. Bigger footprint, recessed floor, frameless glass, a niche and a bench.

I'm not printing a dollar range for either. I can't show you where one would come from, and this is a page about what the after photo hides. Hiding a sourceless number in it would be its own little joke at your expense.

What moves the number: how much plumbing has to move, whether you go curbless, the tile and how much of it, the glass, and whatever we find when the tub comes out. For the full picture on what drives a bathroom price, here's the breakdown: what a bathroom remodel really costs in Tampa Bay.

My honest take

Spend on the waterproofing and the plumbing done right. That's the part that protects your house, and it's the part a cheap quote tends to skip. If you want to understand why that detail behind the tile matters more than the tile itself, read why bathroom waterproofing is the part you can't see. Pick a layout you'll still like in ten years. And keep a tub somewhere in the house if you can.

Common questions

Is a tub-to-shower conversion just swapping one fixture for another?

No, and that's the part the after photo hides. A tub drain and a shower drain aren't in the same spot, so the plumbing moves. Everything before the tile is what earns the number.

What do you usually find behind an old tub?

In a lot of older Tampa Bay homes, water damage that's been sitting there quietly for years. Rotten subfloor, soft framing, sometimes a little mold. We don't know for certain until it's open, and we deal with what we find.

Why do most people make the switch?

Plain, practical reasons. They want a bigger shower that's easier to clean, stepping over a tub wall is getting old, or the kids are grown and the family tub sits dry. A walk-in opens the room up and it's safer getting in and out.
