Duval County's Florida-licensed plumbing contractor for bathroom renovations since 2010
Cummer Jack Plumbing, led by owner Andrew Jackson, provides the plumbing-primary scope of bathroom remodeling for Jacksonville homeowners across Duval, Clay, St. Johns, and Nassau counties. Our Florida Certified Plumbing Contractor license is what makes the difference when your remodel requires a permit from the City of Jacksonville Building Inspection Division — the permits that general bathroom contractors must subcontract a plumber to pull. We are the licensed plumber on your bathroom remodel. For homeowners who also need kitchen remodeling for the plumbing scope of a kitchen renovation as well, we handle both scopes under one license.
From Riverside's 1920s bungalows to Mandarin's ranch homes and beach properties in Atlantic Beach and Neptune Beach
Cummer Jack Plumbing handles bathroom remodeling throughout Jacksonville, Florida — from pre-World War II bungalows and craftsman homes in Riverside, Avondale, and Springfield near Five Points and the Cummer Museum of Art & Gardens, where walls opened during remodeling often reveal original galvanized supply lines, cast iron drain stacks, and knob-and-tube adjacent wiring that must be addressed before any finish work begins, to mid-century ranch homes in Arlington, Ortega, and Murray Hill where slab drain relocation is the most common reason a bathroom remodel costs more than the initial estimate, to newer construction in Baymeadows, Mandarin, Fruit Cove, and Ponte Vedra Beach where bathroom remodels focus on tub-to-shower conversion if your remodel is replacing a bathtub with a walk-in shower, double vanity upgrades, and luxury finish installation, to Jacksonville Beach, Neptune Beach, and Atlantic Beach coastal properties where marine-grade materials and salt-air-resistant fixtures are the right material choice rather than a luxury upgrade.
Riverside, Avondale, Springfield, San Marco, Ortega — pre-1978 homes with galvanized supply lines and original drain stacks
Arlington, Murray Hill, Mandarin, Baymeadows — slab construction where drain relocation requires concrete saw-cutting
Argyle Forest, Beauclerc, Fruit Cove, Nocatee, Ponte Vedra Beach — luxury bathroom upgrades and accessibility remodels
Atlantic Beach, Neptune Beach, Jacksonville Beach, Mayport — marine-grade fixtures, salt-air-resistant materials
Orange Park, Green Cove Springs, Fernandina Beach, Amelia Island, St. Augustine, Yulee, and all of Northeast Florida
The work that requires a license on your Jacksonville bathroom remodel — and why it matters who holds it
Every Jacksonville bathroom remodel that moves a drain, relocates a toilet, roughes-in a new shower, changes supply line connections, or adds a ventilation fan to an exterior wall requires a permit from the City of Jacksonville Building Inspection Division and must be performed by a Florida Certified Plumbing Contractor. When a general contractor or tile company manages your bathroom remodel, they subcontract this work to a licensed plumber — adding coordination layers, scheduling delays, and a second set of markup costs. Cummer Jack Plumbing is the licensed plumber, eliminating the subcontractor layer from the most permit-required scope on any bathroom renovation.
Florida Certified Plumbing Contractor license enables us to pull permits directly from the City of Jacksonville Building Inspection Division for all plumbing work in a bathroom remodel
The most expensive and technically demanding scope in any Jacksonville slab-home bathroom remodel — we do it in-house, no subcontractor markup
Supply connections, drain assembly, and waterproof shower pan installation to Florida Building Code standard — critical for shower repair and replacement for an existing shower that's part of a remodel scope
Proper exterior exhaust routing for humidity-sensing fans per Florida Building Code mechanical code — essential in Jacksonville's high-humidity environment
Required for pre-1978 Riverside, Avondale, and Springfield properties when opening original bathroom walls containing lead paint and pipe solder
The signs that go beyond cosmetic updates — plumbing problems, mold, and structural issues driving Jacksonville bathroom renovations
Jacksonville's humid subtropical climate and diverse housing stock create a specific set of bathroom failure conditions that move homeowners from "this bathroom needs updating" to "this bathroom needs a licensed plumber before anything else." Recognizing the difference between a cosmetic refresh and a project with a plumbing-primary scope helps you budget accurately and choose the right contractor from the first call.
Mold that returns despite cleaning — typically indicates a waterproofing failure behind tile that requires complete shower or tub surround demolition and rebuilding
A shower or tub that feels soft or flexible underfoot — a failed mortar bed or deteriorated subfloor from years of slow water intrusion behind inadequate waterproofing
Water staining on walls or ceilings adjacent to or below the bathroom — a drain connection, supply line, or tile grout failure saturating the structure. Our water leak detection service identifies the source before demolition begins
Corrosion-narrowed pipes in Riverside, Avondale, Springfield, and San Marco homes delivering reduced pressure and discolored water — a remodel opportunity to repipe the affected zone
A bathroom layout requiring moving the toilet, shower, or vanity — the slab relocation scope that is the primary cost driver in Jacksonville's slab-construction neighborhoods
Ready to convert an unused bathtub to a walk-in shower, add a double vanity, or create an accessible master bathroom with a walk-in tub in Ponte Vedra Beach or Mandarin
Homeowners, rental property investors, and coastal property owners across Duval County

Homeowners throughout Northeast Florida whose post-hurricane damage inspection identified water intrusion in the bathroom structure requiring renovation, not just repair
Why Jacksonville bathroom remodels require specific material choices, waterproofing standards, and licensed plumbing expertise that generic national guides miss
Jacksonville's bathroom remodeling market is shaped by three compounding factors that make the city's projects more technically demanding than national cost guides reflect. First, Jacksonville's average indoor humidity of 60–70% makes moisture management critical at every layer of a bathroom renovation — from the waterproofing membrane behind shower tile to the ventilation system exhausting humidity after each shower. Cutting corners in moisture management adds to initial savings and multiplies into mold remediation costs within three to five years in Northeast Florida's conditions. Second, the majority of Jacksonville's mid-century housing stock is slab construction, meaning that any bathroom layout change — moving a toilet across the room, repositioning the shower drain, adding a second sink — requires saw-cutting the concrete slab, relocating the drain rough-in, and repouring the concrete section. This is the single most expensive scope item in Jacksonville bathroom remodeling, and it's work that requires a licensed plumber. Third, Jacksonville's older neighborhoods in Riverside, Avondale, and Springfield carry the "surprise tax" that experienced local remodelers know to expect: once walls are opened, original galvanized piping, outdated drain configurations, and water damage from decades of condensation are frequently found — adding scope that the initial estimate didn't include.
Jacksonville's humidity demands certified waterproof membrane systems behind all wet surfaces — not just tile, but a continuous system at seams, corners, and penetrations
Costs $2,000–$5,000 per drain and requires a licensed plumber with concrete saw-cutting equipment — the primary source of budget surprises in Jacksonville bathroom remodels
Riverside, Avondale, and Springfield homes typically reveal original galvanized supply lines and unlined cast iron drain stacks during demolition — repiping affected zones during the remodel is almost always the correct economic decision
Jacksonville Beach, Neptune Beach, and Atlantic Beach require marine-grade hardware — standard chrome hardware fails within one to two years in beach proximity conditions
Wood or MDF cabinetry without proper moisture-resistant sealing will swell, delaminate, or grow mold in Jacksonville bathrooms — a common callback that proper material specification prevents
Understanding the scope tiers that drive Jacksonville bathroom remodeling costs — and which one your project falls into
For bathroom remodeling Jacksonville FL homeowners are pursuing in 2026, project scope determines cost and complexity more than square footage alone. Keeping the existing plumbing layout saves $2,000–$5,000; moving any drain or supply connection in a slab home triggers the concrete work that moves a project from cosmetic update to licensed plumbing scope.
| Remodel Type | Scope | Jacksonville Cost Range |
|---|---|---|
| Cosmetic Refresh (no plumbing move) | New fixtures, vanity, toilet, tile — existing drain locations | ~$3,000 – $8,000 |
| Walk-In Shower Conversion | Tub removal, shower pan rough-in, glass enclosure, tile | ~$5,000 – $15,000 |
| Master Bathroom Renovation | New layout with existing drain locations preserved | ~$8,000 – $20,000 |
| Full Gut Remodel (with drain relocation) | Slab saw-cutting, new drain rough-in, full rebuild | ~$12,000 – $35,000+ |
| Accessible / ADA Bathroom | Roll-in shower, grab bar blocking, walk-in tub, comfort-height fixtures | ~$8,000 – $20,000 |
| Historic Home Remodel (Riverside / Avondale) | Includes galvanized repipe, original drain replacement | +$3,000 – $8,000 added to base scope |
| Luxury Master Suite Addition | Freestanding tub, double vanity, heated floor, custom tile | ~$20,000 – $58,000+ |
From licensed plumbing design through Florida code-compliant completion
We assess your existing bathroom's plumbing layout, drain locations, supply connections, and structural condition, then discuss your remodel goals — identifying which elements require licensed plumbing scope, whether slab relocation is needed, and what code-specific requirements apply to your Jacksonville property.
For all bathroom remodels involving plumbing work, we apply for the required permit from the City of Jacksonville Building Inspection Division. We manage the permit process — application, documentation, and scheduling the inspection at completion — so you're not navigating the city's process while managing the remodel.
We remove existing fixtures, tile, surround, and flooring, and immediately assess what's found behind the walls — a critical step in Riverside, Avondale, and Springfield homes. Galvanized supply lines, unlined cast iron drains, or previous water damage identified at this stage are scoped and estimated before rebuild begins.
We complete all plumbing rough-in work required before finish materials go in — slab saw-cutting and drain relocation if the layout is changing, supply line repipe in older properties, shower drain and pan rough-in, vanity supply connections, and ventilation fan exhaust routing to exterior.
We apply certified waterproofing membrane systems to all wet surfaces — not just tile adhesive, but a continuous barrier at seams, corners, and penetrations. Tile, vanity, fixtures, lighting, and accessories are installed with Florida-appropriate materials and sealants matched to Jacksonville's humidity and, for coastal properties, salt-air conditions.
The City of Jacksonville Building Inspection Division completes its plumbing inspection. We pressure-test all new supply connections and verify drain function under full flow conditions. A final walkthrough confirms every finish element meets our quality standard before the project is closed.

16 years, award-winning, Florida-licensed — the licensed plumbing scope that makes your Jacksonville remodel code-compliant
When a general contractor says "we'll handle the plumbing subcontractor," that's a coordination cost and a scheduling variable you pay for. Cummer Jack Plumbing is the licensed plumber — permits pulled in-house, slab work done in-house, inspections coordinated in-house — reducing the subcontractor layer from the most regulated scope on your bathroom remodel.
From outdated, moisture-damaged bathrooms to Florida code-compliant, humidity-resistant renovations
Opened to original galvanized supply lines and an unlined cast iron stack behind the tile — supply zone repiped to PEX, drain stack replaced with Schedule 40 PVC, waterproofed shower pan installed, and original floor tile pattern matched with period-appropriate ceramic — permitted and inspected by the City of Jacksonville
Builder-grade tub-shower combo converted to a custom tiled walk-in shower — required concrete saw-cutting to relocate the shower drain 36 inches, new mortar-bed shower pan, frameless glass enclosure, and exterior-vented humidity-sensing exhaust fan — all scoped and permitted in-house
Marine-grade vanity hardware, corrosion-resistant brushed stainless fixtures, and salt-air-rated grout — standard chrome hardware from the previous contractor's installation had already corroded in two years; this remodel was built for beach proximity
Step-in tub converted to a roll-in shower with curbless drain, grab bar blocking in walls, comfort-height toilet replacement, and handheld shower head supply connection — complete accessibility scope under one Florida licensed contractor
Material choices that survive Jacksonville's humidity, hard water, and — for coastal properties — salt air
Continuous certified membrane (Schluter KERDI, RedGard, or Wedi board) at all wet surface seams, corners, and fixture penetrations — not tile grout alone, which cracks and admits moisture in Jacksonville's constant humidity cycling
Porcelain tile rated for wet areas outperforms natural stone in Jacksonville's climate — natural stone requires sealing every 6–12 months in high-humidity environments and stains from the Floridan Aquifer's mineral content
Solid wood with moisture-sealed interiors or thermofoil-wrapped MDF for humidity resistance — standard particleboard MDF without proper sealing fails in Jacksonville bathrooms within 3–5 years
Brushed nickel or matte black finishes last longer than chrome in Jacksonville's humidity; marine-grade stainless or coated brass for Jacksonville Beach, Neptune Beach, and Atlantic Beach coastal properties
Humidity-sensing exhaust fans (50+ CFM per Florida Building Code) routed to exterior — not recirculating fans, which only move humid air in circles in a Jacksonville bathroom
Epoxy grout at shower floors and the tub-to-floor joint — more expensive than sanded grout but eliminates the regrouting cycle that Jacksonville's humidity-accelerated grout degradation creates
The scope decision that determines your permit requirement, your plumbing budget, and your contractor choice
Jacksonville's bathroom project options fall into three distinct tiers — each with different permit requirements, cost ranges, and contractor qualifications. Understanding which tier your project falls into prevents the budget shock that comes from starting a "cosmetic update" that reveals a plumbing scope.
| Project Tier | What It Involves | Permit Required | Who Performs It |
|---|---|---|---|
| Cosmetic Refresh | New paint, vanity swap, toilet swap, accessory update — no drain moves | Usually no permit required | General contractor or DIY with licensed plumber for fixture swap |
| Mid-Range Remodel | New tile, shower surround, fixtures, vanity — drain locations preserved | Permit required for plumbing connections | Florida Licensed Plumbing Contractor |
| Full Gut or Layout Change | Slab saw-cutting, drain relocation, full rebuild, complete new plumbing rough-in | Permit required — plumbing and electrical | Florida Licensed Plumbing Contractor + inspections |
From a $3,000 cosmetic refresh to a $35,000+ full master bathroom renovation
Jacksonville bathroom remodeling costs are driven more by plumbing scope — specifically whether any drain moves — than by square footage or fixture quality. We provide a written estimate before any work begins.
| Project Scope | Jacksonville Cost Range |
|---|---|
| Cosmetic refresh (no plumbing moves) | ~$3,000 – $8,000 |
| Walk-in shower conversion | ~$5,000 – $15,000 |
| Full bathroom remodel — existing layout | ~$6,769 – $9,348 (Jacksonville avg) |
| Full bathroom remodel with slab relocation | ~$12,000 – $25,000 |
| Master bathroom addition or gut renovation | ~$15,000 – $35,000+ |
| Luxury master suite build-out | ~$35,000 – $58,000+ |
| Historic home remodel (Riverside/Avondale) | Base scope + $3,000 – $8,000 contingency |
Analysis of 81 real Jacksonville contractor bids shows $166–$297 per square foot range. Average Jacksonville bathroom remodel based on 24,594 completed local projects is $6,769–$9,348.

Your Riverside, Avondale, or Springfield bathroom needs updating and you suspect — or know — there's original galvanized piping or cast iron drain work to address
Your master bathroom feels outdated, cramped, or poorly configured and you want to move the toilet or shower — requiring slab saw-cutting in Jacksonville's slab-home neighborhoods

You're preparing a Jacksonville Beach or Neptune Beach rental for higher rental rates and better guest reviews with a remodeled bathroom

What happens when a Jacksonville bathroom remodel is completed without the required City of Jacksonville permits
The City of Jacksonville Building Inspection Division requires permits for all bathroom plumbing work — drain moves, supply line changes, new shower rough-in, and toilet relocation. A bathroom remodel completed without these permits creates several documented risks for Jacksonville homeowners that typically materialize at the worst possible time.
Answers about cost, permits, slab relocation, historic homes, and Jacksonville's timeline for bathroom renovations
Based on analysis of 81 real contractor bids and 24,594 completed Jacksonville projects, bathroom remodeling costs range from $2,898 to $14,100, with an average of $6,769–$9,348 for a standard full bathroom remodel. The critical variable is whether any drain relocates in your slab-built home — adding $2,000–$5,000 per moved fixture. Historic Riverside and Avondale homes typically add $3,000–$8,000 in discovered-work contingency once walls are opened. Call (904) 227-4220 for a free estimate specific to your Jacksonville property.
Yes, if any plumbing work is involved — drain relocation, supply line changes, shower rough-in, toilet relocation, or new fixture connections. The City of Jacksonville Building Inspection Division requires permits for all licensed plumbing work, and unpermitted plumbing discovered at home sale creates legal disclosure obligations and potential remediation requirements. Cummer Jack Plumbing handles permit applications as the Florida Certified Plumbing Contractor of record.
Jacksonville's mid-century and modern housing stock is predominantly slab construction. Moving any drain in a slab home requires saw-cutting the concrete floor to the drain's current location, demolishing the existing drain rough-in, installing new drain pipe at the revised location, and repouring the concrete section. This work requires a licensed plumber with concrete saw-cutting equipment and adds $2,000–$5,000 per relocated fixture beyond the base remodel cost.
Once walls are opened in pre-World War II homes in Riverside, Avondale, and Springfield, original galvanized supply lines, unlined cast iron drain stacks, and outdated electrical conditions are frequently discovered. Jacksonville remodeling professionals refer to this as the "surprise tax" — and the standard local guidance is to budget a $3,000–$8,000 contingency before demolition begins. Repiping the affected zone and replacing the drain stack during the remodel, when walls are already open, is almost always more economical than addressing these issues after the finished bathroom has been completed.
