The short answer: yes, but plan the complete wet area before removing the tub
Can a bathtub be replaced with a walk-in shower in a Southwest Florida home? Usually, yes. The simplest projects keep the shower in the same general footprint and reuse practical supply and drain routes. The work becomes more involved when the drain must move through a concrete slab, the shower needs a curbless entrance, walls contain deterioration, or the new enclosure is larger than the old tub area.
A dependable proposal should address demolition, plumbing, wall backing, waterproofing, shower base, tile or panels, valve and trim, glass, flooring transitions, ventilation, permits and inspections. Choosing attractive tile before resolving those hidden conditions can lead to redesign, change orders or a shower that is difficult to use.
1. Decide why you are removing the bathtub
The design should respond to the reason for the conversion. A homeowner seeking easier daily access may prioritize a low curb, stable footing, a handheld spray and future grab-bar locations. A guest bathroom may need a simpler, durable layout. A resale-focused project should consider whether the house will still have another bathtub for households that value one.
Write down the must-have features before selecting finishes. Door width, entry direction, bench size, controls and storage affect the usable shower more than a tile sample does. If mobility needs are important, discuss them directly with the contractor; the phrase walk-in shower does not automatically mean an accessible or curbless design.
2. Measure the room, not only the tub alcove
A standard-looking tub alcove can hide uneven walls, a shallow plumbing chase or limited clearance near the toilet and vanity. Field measurements should record the opening width and depth, ceiling height, window location, door swing, floor elevation and the space available for a glass door to operate.
Mock up the proposed entry with tape on the floor. Confirm that the user can approach the shower, open the glass, reach the controls without standing under cold water and exit onto a safe landing area. A larger shower is not automatically better if it narrows circulation or creates an awkward door conflict.
3. Verify the drain location, trap and route
A bathtub and shower do not necessarily use the same drain arrangement. The existing outlet may sit near one end of the tub, while the selected shower base or tile layout may call for a different location. The contractor must determine whether the drain, trap and vent arrangement can support the proposed design under the applicable plumbing requirements.
In many Southwest Florida slab-on-grade homes, moving the drain can require controlled concrete cutting and excavation. That affects dust protection, plumbing access, inspection timing and slab restoration. Do not order a fixed shower base until its drain position has been coordinated with the actual plumbing conditions.
4. Inspect supply lines and choose the valve early
Demolition exposes the hot and cold supply piping, valve connection and wall cavity. Existing piping may be suitable for connection, or its material and condition may justify additional work. Any deterioration, poor support or concealed leak evidence should be documented before the wall is closed.
Select the shower valve, trim, showerhead, handheld spray and any body outlets early enough to plan the rough-in. Different products require different depths, blocking and pipe layouts. Confirm which components are included; a trim kit displayed online may not include the required in-wall valve or every accessory shown.
5. Treat waterproofing as a complete system
Tile and grout are finish materials, not the entire water-control strategy. The shower needs a coordinated base or receptor, drain connection, wall substrate, waterproofing system, corners, penetrations and transitions. Mixing unrelated materials without a clear installation plan can create weak points behind a visually attractive surface.
Ask the proposal to identify the waterproofing approach and the limits of the wet area. Niches, benches, curbs, half walls and windows add transitions that need deliberate detailing. Required tests and inspections depend on the permit and jurisdiction, so the contractor should build the schedule around the approved process rather than covering work prematurely.
6. Compare a curbed, low-threshold and curbless entry
A conventional curb is often easier to integrate because it helps contain water and provides a defined edge for glass. A low-threshold receptor can reduce the step while keeping a manufactured slope and drain relationship. A curbless shower can improve access, but it generally requires more control over floor elevations, slope and water containment.
In an existing slab home, a curbless design may require recessing or modifying the shower area rather than simply installing tile level with the bathroom floor. Doorless concepts also need enough depth and spray control to keep water inside. Choose the entry type after evaluating structure, drainage and room layout—not from appearance alone.
7. Plan blocking, seating and storage before walls close
Grab bars and fold-down seats need secure attachment, so their locations should be planned before wall board and waterproofing. Even if the owner does not want bars now, documented backing can preserve options for later. Blocking may also be needed for heavy glass, shower doors or wall-mounted accessories.
A bench should leave enough standing room and should not interfere with the entry or controls. Niches need to fit within the wall framing without conflicting with plumbing, electrical work or exterior-wall conditions. Small corner shelves may be a better choice when a niche would complicate the waterproofing or wall layout.
8. Coordinate glass before finalizing tile and curb dimensions
Frameless and framed enclosures have different support, clearance and tolerance needs. Glass installers rely on the finished opening, but the construction team needs the intended glass layout earlier to plan backing, curb width, wall alignment and door swing.
Wait for final field measurements after tile or wall panels are complete unless the glass provider directs otherwise. Confirm door hardware, handle location, fixed panels and the gap needed for nearby fixtures. A clean design on paper can fail in use if the door hits a vanity, towel bar or toilet.
9. Resolve flooring, paint and ventilation transitions
Removing a tub can expose unfinished wall edges or a gap in the bathroom floor. The proposal should state how tile, baseboard, drywall texture and paint will meet the new shower. Matching an older floor tile exactly may be impossible, so a planned threshold or intentional transition can look better than a small mismatched patch.
Bathroom ventilation should also be reviewed, especially when the new shower produces more exposed moisture than the former tub was used to create. Verify that the exhaust fan operates, terminates appropriately and is included in the project only if its alteration is part of the written scope. Electrical changes near the wet area require separate coordination.
10. Confirm permits and inspections for the address
Permit requirements depend on the jurisdiction and work involved. Charlotte County's current residential plumbing page covers installation or replacement of plumbing elements in an existing residence and notes that some like-for-like fixture replacements may not require a permit, while advising owners to check before starting. A tub-to-shower conversion may change the drain, valve, waterproofed area or room configuration, so it should not automatically be treated as a simple fixture swap.
Port Charlotte properties may be under Charlotte County, while work inside the City of Punta Gorda follows the city's process. Confirm the authority having jurisdiction for the exact address, the permit type and the inspections shown on the job card. Keep approved documents available and do not conceal work that must be inspected.
11. Compare proposals by completed scope
One price may include demolition through paint and glass, while another stops after setting the receptor. Compare the same completed result. Identify who handles debris, plumbing, slab work, wall repair, waterproofing, tile, fixtures, glass, permits, inspections and final cleanup.
Allowances should name the included amount and what it covers. Ask how concealed deterioration, corroded piping or unexpected slab conditions will be documented and approved. Financing may be available for select qualifying remodeling projects depending on the project and provider, but Model Construction Corp is not the lender and approval, rates and terms cannot be guaranteed.

Before the first wall is opened, confirm the decisions that affect rough plumbing and waterproofing. This short checklist helps keep design choices aligned with the construction sequence.
- Reason for the conversion and required accessibility features
- Measured layout, entry direction and glass-door clearances
- Proposed drain location and expected slab work
- Selected valve, showerhead, handheld spray and accessories
- Curbed, low-threshold or curbless entry strategy
- Waterproofing system and limits of the wet area
- Blocking for glass, seats and future grab bars
- Tile or panel selections and flooring transitions
- Permit authority, inspection stages and responsible contractor
- Written inclusions, exclusions, allowances and concealed-condition process
Build the shower around the room and the people using it
A bathtub-to-shower conversion works best when plumbing, waterproofing, entry height, storage and glass are designed together. Evaluating the existing room before demolition gives the homeowner a more realistic scope and helps prevent finish decisions from driving impractical construction.

Quick answers
Frequently asked questions
Can any bathtub be converted into a walk-in shower?
Most can, but the practical design depends on room dimensions, drain and supply locations, slab or floor construction, wall condition and the desired entry. An onsite evaluation is needed before selecting the shower base and glass.
Do I need to move the drain for a tub-to-shower conversion?
Not always. Some shower systems can work with an offset drain, while other layouts require relocation. The contractor should coordinate the drain position, trap, vent and selected base before materials are ordered.
Is a curbless shower possible on a concrete slab?
It may be possible, but it usually needs careful elevation, slope, drainage and slab planning. Feasibility depends on the existing structure and room, so it should be evaluated before demolition.
Does Charlotte County require a permit to replace a tub with a shower?
Requirements depend on the scope. Charlotte County advises that some like-for-like fixture replacements may not need a permit, but a conversion that changes plumbing or the wet area may require one. Verify the address and proposed work before starting.
Should shower glass be measured before tile installation?
Final glass measurements are normally based on the completed surfaces unless the glass provider specifies another process. The intended glass layout should still be coordinated earlier for blocking, curb size and door clearance.
Will removing the bathtub hurt resale value?
It depends on the home and likely buyer. Keeping at least one bathtub may matter to some households, while an easier-entry shower may be more useful to others. Consider the remaining bathrooms and intended ownership plan.
