Tub-to-Shower Conversion Cost & Process in Louisiana

A tub-to-shower conversion in Louisiana should start with a written scope that separates the core job from optional upgrades. In scope for this guide: removing the tub, evaluating subfloor and framing, relocating or adapting the drain and valve, installing a shower base or site-built pan, waterproofing walls, adding tile or panels, setting glass or curtain hardware, and testing drainage. The contractor should also define dust control, protection of existing finishes, work hours, debris removal, daily site cleanup, product allowances, and who communicates inspection dates. This is the practical middle of the market: more than a single repair visit, but less than a custom whole-house reconstruction.

Out of scope unless the proposal says otherwise: moving structural walls, enlarging the bathroom, whole-house repiping, mold remediation beyond the opened area, custom steam systems, window replacement, and major electrical redesign unless specified. Those items can be legitimate, but they change risk, schedule, permits, and the trades required. The safest contract names the prime contractor, each licensed trade, the products or allowances, payment milestones, and the conditions that trigger a written change order. Louisiana licenses contractors at the state level through the Louisiana State Licensing Board for Contractors (LSLBC) for commercial work over $50,000 and residential work over $75,000. Home improvement projects of $7,500–$75,000 require a Home Improvement Registration. For this project, relevant credential checks commonly point to: Louisiana State Licensing Board for Contractors (LSLBC); Louisiana State Plumbing Board; Louisiana LSLBC — Electrical Work classification.

The state-content-2026-06 costBand for Louisiana lists General contractor remodel at $5,500 low, $30,000 typical, and $95,000 high. A tub-to-shower conversion sits below a full bath remodel but above a simple fixture swap because waterproofing, plumbing, glass, and accessibility details control risk. After that project adjustment, a planning range for this tub-to-shower conversion is $2,500 low, $13,500 typical, and $34,000 high.

Use those figures as a budget screen, not a quote. The low end assumes standard access, ordinary finishes, no major hidden damage, and a clean permit path. The high end reflects premium materials, difficult access, older homes, multiple inspections, structural or utility coordination, and change orders discovered after opening walls, roofs, or equipment spaces. For bid comparison, ask each contractor to separate labor, materials, permit fees, allowances, disposal, access assumptions, and change-order rates so a low headline price does not hide missing scope. For larger scopes, ask whether the bid assumes owner-supplied products, occupied-home protection, temporary utilities, final cleanup, disposal, and return trips after inspections. Confirm mobilization, warranty exclusions, sales tax assumptions, and documentation responsibilities separately for every bid before signing.

A conversion commonly needs plumbing and building review when the drain, valve, shower pan, waterproofing, or safety glazing changes. Electrical permits may apply for new lighting, fan controls, heated floors, or receptacle changes. The state licensing source matters because a contractor license or registration is not the same thing as a project permit. Louisiana licenses contractors at the state level through the Louisiana State Licensing Board for Contractors (LSLBC) for commercial work over $50,000 and residential work over $75,000. Home improvement projects of $7,500–$75,000 require a Home Improvement Registration. The project-specific licensing notes in the seed say: required at or above $50,000 through Louisiana State Licensing Board for Contractors (LSLBC); Commercial work $50K+, residential work $75K+, mold remediation $7.5K+. required at or above $7,500 through Louisiana LSLBC — Home Improvement Registration; Required for residential improvement projects $7,500–$75,000. required through Louisiana State Plumbing Board

For permits, verify the authority having jurisdiction before signing: city building department, county building department, consolidated permit office, or in some areas a separate utility or fire review. Ask who pulls the permit, whose license appears on it, whether owner-builder filing is allowed, which inspections occur before work is covered, and whether final approval is required before final payment. Keep the permit card, inspection approvals, and stamped plans or online permit record with the contract.

A standard acrylic conversion can take one to two weeks after materials arrive; tiled showers, drain relocation, glass fabrication, flood testing, and failed inspections can push the work to three to six weeks. Louisiana projects must account for humidity, wind-driven rain, coastal corrosion in some counties, and tropical-storm season. Build in weather float during hurricane season and confirm dry-in, condenser anchoring, or wind-resistance details before work starts.

Because permit review is municipal rather than one statewide queue, treat the timeline as two tracks: approval and inspection scheduling on one side, materials and crew availability on the other. A contractor who gives a firm start date should also name the permit filing date, long-lead products, inspection hold points, and weather or utility conditions that can move the calendar.
