Low-threshold conversion
Often fits when
The main problem is stepping over the tub wall and the person can still cross a small shower lip safely. A tub-footprint base can keep the project focused on the wet area.

The contractor confirms the project
The selected contractor measures the site, verifies the technical scope and approvals, provides the quote, and performs the work.
Choose the right level of change
Is a tub-to-shower conversion enough?
Removing the tub wall solves one important barrier. The remaining threshold, opening, floor space, and transfer method determine whether a standard conversion goes far enough.
True zero-entry or roll-in shower
Compare when
Even a small lip is difficult, direct wheeled access is needed, or transfers and caregiver assistance require a wider, level entrance and more coordinated floor space.
Tub cut-out
A smaller alternative
An opening is cut into the existing tub wall to reduce step-over. It is less disruptive, but it does not replace the tub with a shower and does not create curbless or roll-in access.
What the project can include
What happens during a tub-to-shower conversion?
A complete scope addresses more than the visible shower walls. It should explain demolition, plumbing, water control, accessibility features, finishes, and closeout.
Tub removal and disposal
Protect the home, remove the existing fixture and surround as needed, and state who hauls away debris.
Drain and plumbing assessment
Verify the existing drain, trap, slope, venting, valve, supplies, and compatibility with the selected shower system.
Base or shower pan
Install a compatible prefabricated base or build a custom pan with the required threshold, slope, drain, and support.
Walls and waterproofing
Identify the substrate, waterproofing or receptor system, seams, corners, penetrations, niches, and drain connection.
Accessibility features
Coordinate structural support and placement for grab bars, seating, handheld spray, controls, and a wet-use floor surface.
Opening and finish work
Plan a curtain or enclosure, patch adjacent floor and walls, complete inspections, clean up, and provide warranty information.
Focused wet-area conversion
- Tub footprint largely stays the same
- Toilet, vanity, and room layout remain
- Compatible drain side may stay
- Factory base or conventional pan
- Limited adjacent finish repair
Larger bathroom remodel
- Drain or supplies move substantially
- Shower expands beyond the tub footprint
- Walls, doors, or other fixtures move
- True curbless floor reconstruction
- Extensive slab, damage, electrical, or room-floor work
A conversion becomes a remodel through accumulated scope—not simply because the homeowner chooses an attractive finish.
Thresholds are not interchangeable
Bathtub vs. low threshold vs. zero entry
Measure the actual tub wall and proposed shower threshold. A low threshold removes most of the barrier, while zero entry changes how the floor, slope, drain, and water containment work together.
Bathtub
The user must cross the tub wall before reaching the bathing floor.
Low threshold
A small raised lip remains and contributes to water containment.
Zero entry
The room transition is level; the shower floor slopes inward to the drain.
A high-value site question
Can the existing tub drain stay where it is?
Sometimes. Tub-footprint shower bases are made with left- and right-hand drain locations, so a centered drain is not automatically required. The contractor still needs to verify the trap and pipe condition, slope, venting, drain elevation, shower flow, selected system, and the rules that apply to the project.
Florida does not impose a universal 2-inch shower-drain rule
Under the current 8th Edition (2023) Florida Plumbing Code, a shower flowing 5.7 gallons per minute or less can use a 1½-inch waste outlet. Higher-flow systems require larger drainage. That does not mean every existing tub drain is reusable—it means the real installation must be inspected instead of applying a blanket internet rule.
- Existing drain side and elevation
- Trap, pipe, slope, and vent condition
- Selected base or custom-pan requirements
- Concrete slab or structural-floor implications
Choose the complete shower system
Panel systems, tile, bases, pans, and enclosures
No finish is automatically best. Compare cleaning, layout flexibility, construction time, repair strategy, and how well the complete assembly supports the user.
Acrylic, fiberglass, or composite systems
Factory-sized bases and wall systems can reduce joints and installation labor. Their fixed dimensions, threshold, drain location, backing, and accessory options must fit the home.
Solid-surface or cast-polymer panels
Large panels offer fewer wall joints and a residential finish. Weight, seams, backing, fabrication, cleaning instructions, and repairability vary by product.
Tile with a prefabricated base
A factory base can make floor geometry more predictable while tile walls provide finish flexibility. Waterproofing details still matter behind the wall tile.
Custom tiled shower
Tile can accommodate custom geometry and curbless work, but requires more labor and a well-executed pan, membrane, drain, substrate, and cure or test sequence.
Curtain or open entrance
Often preserves a wide, flexible opening and can simplify caregiver access. The slope and splash pattern must still keep water from creating a new floor hazard.
Glass enclosure
Framed or frameless glass can improve containment, but door width, swing, fixed panels, lead time, cleaning, and transfer clearance should be considered before appearance.
Design around everyday bathing
Accessibility features work as a system
The right layout follows how the person enters, stands, sits, reaches, transfers, and receives help—not a generic package labeled “ADA.”
Entry and maneuvering
Confirm the usable opening, walker or wheelchair approach, nearby toilet or vanity conflicts, and room-side space.
Seat and transfers
Decide whether bathing is seated, whether transfer starts outside the shower, and whether a fold-down seat protects shared floor space.
Reachable controls
Plan controls and a handheld sprayer for standing and seated use, ideally without requiring the user to stand under the spray to start the water.
Grab-bar support
Placement should follow actual movement and transfer patterns while the wall assembly provides dependable structural attachment.
Door, curtain, and caregiver access
Avoid fixed panels or door swings that block a walker, wheelchair, transfer path, controls, or a caregiver.
Traction and water control
Choose a wet-use textured or slip-resistant surface and make sure splash, slope, drainage, and drying do not create a new hazard.
ADA dimensions are useful accessibility references, but the ADA does not automatically govern an ordinary private single-family bathroom. The project should satisfy the person’s needs and the code, permit, property, and association requirements that actually apply.
What is behind the finish matters
How should a shower be waterproofed?
Tile and grout are the visible finish—not the complete water-control strategy. The written scope should identify the receptor or membrane system and how it integrates with every transition and the drain.
- What waterproofing or receptor system will be used?
- Where does it extend on the floor and wet-area walls?
- How are the drain, seams, corners, niches, seats, and penetrations treated?
- What inspection or manufacturer-prescribed water test applies before finishes hide the work?
- How will previous leaks or damaged substrate be handled and priced?
Florida’s current shower-receptor provisions require site-built lining to be watertight and sloped toward the drain—about ¼ inch per foot. Test timing varies by the chosen system, so the contractor should follow that manufacturer’s instructions rather than a universal waiting period.
Local project planning
South Florida tub-to-shower considerations
The exact property and scope matter more than a county label. These questions should be resolved before anyone promises a fixed design, permit path, or schedule.
Drain and slab work
When drainage is below concrete, relocation can involve demolition, plumbing, inspection, and slab restoration. Keeping a compatible drain side may materially simplify the project.
Permitting jurisdiction
Plumbing alterations, electrical changes, and structural or slab work are common permit triggers. The contractor should identify the correct city or county authority and written permit responsibility.
Condo or building rules
Verify association approval, insurance, work hours, shutoffs, service access, common plumbing, waterproofing rules, and any restriction on slab cutting before pricing a complex scope.
Project calendar
Separate approval and material lead time from days of active construction. Custom tile, inspections, concealed damage, slab work, and made-to-measure glass extend the schedule.
A realistic sequence
How long does a tub-to-shower conversion take?
The fastest standardized systems and a custom tiled or curbless shower are different projects. Ask for both the total calendar and the expected days the bathroom will be unavailable.
- 01
Before construction
Assessment, site verification, design decisions, contractor proposal, association review, permits, ordering, and scheduling.
- 02
Active work
Protection, demolition, rough plumbing, repairs, base or pan, waterproofing, walls, accessories, finish work, and cleanup.
- 03
Closeout
Applicable inspections, manufacturer steps, punch list, operation review, warranty delivery, and custom glass if measured after finishes.

Clear answers
Tub-to-shower conversion FAQ
Is a tub-to-shower conversion the same as a zero-entry shower?
No. A low-threshold conversion still has a small raised lip. A true zero-entry or curbless shower has a level room-to-shower transition and requires the floor elevation, slope, drain, and waterproofing to work together. The person’s mobility and the existing construction determine which is appropriate.
Can the existing tub drain stay where it is?
Sometimes. Tub-footprint shower bases are available with left- and right-hand drains, so a centered drain is not automatically required. A contractor still needs to verify the trap, pipe condition, slope, venting, drain elevation, selected system, flow rate, and applicable project requirements.
Does a shower drain have to be two inches in Florida?
Not universally. Under the current Florida Plumbing Code, a shower flowing 5.7 gallons per minute or less can use a 1½-inch waste outlet; higher-flow systems require larger drainage. That does not guarantee an existing tub drain can remain—the actual system must be inspected.
What work is included in a tub-to-shower conversion?
A complete scope can include protection, tub removal, disposal, plumbing assessment, a shower base or custom pan, wall substrate, waterproofing, finish walls, valve and fixtures, grab-bar or seat support, an enclosure or curtain, adjacent finish repair, inspections, cleanup, and warranty. Confirm each item in writing.
Is tile better than an acrylic or panel shower system?
Not automatically. Factory bases and panels can reduce joints and field labor, while tile allows more customization and custom-pan or curbless geometry. Compare cleaning, threshold and drain options, waterproofing, accessory support, repair strategy, installation time, and the needs of the person using the shower.
How should a tiled shower be waterproofed?
Tile and grout are finishes, not the complete water-control system. The scope should identify the receptor or membrane, its connection to the drain, treatment of seams, corners, penetrations, niches and seats, and the inspection or manufacturer-prescribed test that occurs before finishes hide the work.
Do I need a permit for a tub-to-shower conversion?
Permit requirements depend on the exact work and local jurisdiction. Moving or altering plumbing, electrical changes, and structural or slab modifications are common reasons permits or trade permits may be required. The contractor should identify the responsible authority and permit scope in writing.
How long does a tub-to-shower conversion take?
A standardized system can require only a short period of active installation once materials and approvals are ready, while custom tile, drain or slab work, inspections, concealed damage, curbless construction, and made-to-measure glass take longer. Ask for the total calendar and the expected days the bathroom will be unavailable.
Where should grab bars, the seat, and controls go?
Placement should follow how the person enters, stands, sits, reaches, transfers, and receives caregiver help. The wall structure must also support the products. ADA dimensions can be useful references, but they do not automatically govern every ordinary private residential bathroom.
Should a home keep at least one bathtub?
It depends on the household and future plans. Some future buyers and families with young children may prefer a tub, but no reliable evidence supports a universal percentage penalty for removing the last one. The resident’s daily safety and access needs should be weighed alongside resale preferences.
How much does a tub-to-shower conversion cost?
Current 2026 professional wet-area guidance commonly places installed conversions around $8,000 to $15,000. Keeping the drain and footprint can control cost; plumbing changes, tile, glass, curbless work, hidden damage, permits, and condo requirements can move it higher.
