Short answer: usually yes, and that is the main reason tub-to-shower conversions are one of the more contained bathroom projects you can do.
The tub and the shower that replaces it are typically served by the same drain and the same supply lines. When the new shower goes back into the same alcove, those connections stay roughly where they are. The work that follows is mostly demolition, preparation and installation rather than re-plumbing.
That said, “usually” is doing real work in that sentence. Here is what actually determines it.
Why the connections normally stay put
A standard alcove tub sits against three walls with the drain at one end and the valve in the wall above it. A shower built into that same alcove uses the same two points. The drain moves from a tub shoe to a shower pan drain, which sits in a similar spot, and the valve stays in the wall it is already in.
So the honest version is that the plumbing usually stays in roughly the same place, though the drain fitting, the valve or the connections themselves may still need adjusting. That is different from relocating a drain across the room, which is a much larger job.
What can still change the picture
The pan drain does not line up
Tub drains and shower pan drains are not always in the identical position. Depending on the pan you choose, the drain may need to shift by a few inches. On a home with a crawl space that is straightforward. On a slab it can mean a small concrete cut, which changes the scope.
The valve has to be replaced anyway
Tub and shower valves are not the same part. A tub filler spout is fed differently from a shower-only valve. In most conversions the valve gets replaced regardless, which means opening the wall behind it. That is normal and planned for, but it is wall work, not a swap.
Something behind the wall is not in good shape
Old supply lines, a subfloor that has taken water over the years, or framing that was cut about in an earlier renovation only become visible once the tub comes out. None of that is unusual. It does mean the plan should allow for it.
You want the shower bigger than the tub was
If the new shower extends past the original alcove, you are no longer working inside the existing footprint. At that point walls, framing and sometimes the drain all come into play, and the project belongs in a different category.
Permits
Worth checking early rather than assuming either way. In Duval County, plumbing changes and relocations generally require a permit, and whether the rest of the work does depends on exactly what is being altered. Keeping the shower inside the existing alcove does not automatically mean no permit is needed. Confirm the requirement for your specific project with the City of Jacksonville before work begins.
What the job actually involves
In a typical same-footprint conversion:
- The tub and surround come out, along with the wall material behind them
- The valve is replaced and the supply lines are checked where they are accessible
- The pan is set and leveled, and the drain connection is made
- The wall system goes in, whether that is an acrylic or solid-surface surround or tile
- The door or screen, the fittings and the trim go on last
That is the shape of it. The variables are the condition of what is behind the wall and the material you choose, not the plumbing layout.
Is it worth doing
Depends on who uses the bathroom and what else the house has.
A tub-to-shower conversion tends to make sense when the tub is only ever used as a shower, when stepping over a high tub wall has become awkward, or when the tub itself is past the point where refinishing helps. If you want the detail on the last one, the signs a shower needs replacing rather than repairing covers the failure modes worth watching for.
It tends to make less sense when it is the only tub in the house and you have young children, or when you are planning to sell soon and the house would be left with no bathtub at all. Walk-in shower or keep the bathtub works through that decision in more detail.
How this affects cost
Staying inside the existing footprint is the version of the job with the fewest unknowns, which is generally reflected in the quote. The things that move the number are the material grade you choose, the condition of what is found behind the wall, and whether anything has to move. What affects the cost of a bathroom remodel in Jacksonville goes through those factors properly.

Frequently asked questions
Does converting a tub to a shower require moving the drain?
Usually not by much. The shower pan drain sits in a similar position to the tub drain, so in most same-alcove conversions the connection stays close to where it already is. Some pans need the drain shifted a few inches, which is a smaller job than relocating it across the room.
Do I need a permit to convert a tub to a shower in Jacksonville?
It depends on what is being altered. Plumbing changes and relocations generally require a permit. Keeping the shower in the existing alcove does not automatically mean a permit is unnecessary, so confirm the requirement for your project with the City of Jacksonville before work begins.
Will the shower be the same size as the tub?
If it goes back into the same alcove, yes, roughly. A standard alcove gives you a shower around the footprint of the tub that was there. Going wider means moving walls, which is a different project.
Does removing the only bathtub hurt resale?
It can, in a house with no other tub, particularly for buyers with young children. In a house with two or more bathrooms where at least one tub remains, it is far less of an issue.
Can the shower be made easier to step into?
Yes. Low-threshold and barrier-style pans are a common part of a conversion, and they are one of the more practical reasons homeowners do this in the first place.
