What Walk-In Showers & Shower Remodeling Actually Costs and Takes in Marco
A walk-in shower remodel in Marco typically runs $9,000 to $28,000, with most complete replacements landing between $12,000 and $18,000 when no plumbing is relocated. The job usually takes five to seven working days from demo to final silicone cure, and you’ll want a permit pulled. Call us at (844) 638-7249 for a walk-through and a number that sticks.
On a barrier island like Marco, this job carries a few wrinkles. Salt air eats cheap fasteners and unsealed grout fast, and a lot of the original Deltona-era concrete block homes have bathrooms boxed into tight interior footprints where moving a drain means saw-cutting the slab. None of that is a dealbreaker if you know it’s coming, and we plan for it from the first measurement.
How a Walk-In Shower Remodel Comes Together, Step by Step
The real sequence is predictable once you’ve done a few hundred of them. We walk every homeowner through this before we hand you a written estimate, because you should know what happens on day three and what decisions need to be locked in by day one.
Stage 1: Demo and slab inspection. We protect the floor path, remove the existing shower pan, surround, and any wet drywall or tile back to the studs, and expose the drain and trap. On a Marco slab-on-grade home, this is where we check the condition of the cast-iron or PVC trap embedded in the concrete, and confirm whether the drain location needs to shift. This stage takes a full day. Your decision here is whether to keep the existing drain center or move it, which adds cost and a day to the schedule.
Stage 2: Rough plumbing and valve work. The plumber sets the new mixing valve, moves supply lines if you’re changing where the showerhead lands, and ties the drain to the existing trap or a new location. In a Deltona-era CBS home, moving a drain means saw-cutting the slab, sleeving the pipe, and repouring concrete around it. This stage is one to one and a half days. On day two, you need to have your valve trim and showerhead style locked in, because the rough-in dimensions depend on them.
Stage 3: Waterproofing, pan, and prep. We build the sloped mortar bed or set a pre-formed foam pan, then waterproof the entire shower footprint with a bonded sheet membrane or liquid-applied system that ties into the drain flange. Walls get the same treatment up to the showerhead height or to the ceiling depending on your steam or enclosure plans. Curing takes 24 hours. At this point you should have your Backsplash, Tile & Flooring in Marco selections finalized, including grout color, niche dimensions, and any bench or shelf layout. No changes after waterproofing without starting over.
Stage 4: Tile and solid-surface installation. Wall and floor tile go in across two to three days, with a day of curing before grouting. We install niches, corner shelves, and any solid-surface bench tops during this stage. Grouting and silicone sealant at all change-of-plane joints wrap up the wet work. If you chose a pre-cast solid-surface shower base and wall panels instead of tile, this stage compresses to a single day, which is a meaningful timeline advantage on a vacation home job.
Stage 5: Glass, door, trim, and finish. Framed or frameless glass enclosure installation happens after tile is fully cured, usually day six or seven. The plumber returns to install the showerhead, valve trim, and any handshower or body-spray trim you selected. We run the shower, check for leaks, test the drain, and caulk the final seams. Your walk-through with Derek or the job lead happens at the end of this day so nothing gets signed off until you see it running.
Throughout the whole sequence, you’ve got one number to call if a question comes up at 8 p.m. or on a Saturday. A live person answers, always.
The Decisions That Shape Your Shower
Most of the cost difference between a $9,000 shower and a $28,000 shower comes down to four or five choices you make before we order materials. The list below walks through what you’re choosing between, with the honest trade-off on each.
- Curbless vs. curbed entry. A curbless walk-in sits flush with the bathroom floor and is the most-requested option in Marco right now, especially for homeowners planning to age in place. It requires recessing the shower pan into the slab, which means saw-cutting concrete. A curbed entry keeps the pan above the slab and costs less. On an elevated home where the subfloor is wood-framed, curbless is often simpler and sometimes cheaper than on slab.
- Tile vs. solid-surface walls. Tile offers unlimited design flexibility and a custom look, at the cost of grout maintenance and a longer install timeline. Solid-surface panels from brands like Kohler or Swan are grout-free, install in a day, and hold up well against Marco’s humidity and salt air, but your color and texture options are narrower. If the bathroom is a guest shower that needs to be bulletproof and easy to clean, solid surface wins.
- Framed vs. frameless glass. Frameless heavy-glass enclosures feel open and high-end, but they cost more for both the glass and the precise install. A framed enclosure is less expensive and seals tighter, which matters less in a well-ventilated bathroom but can matter in a small Marco condo where humidity management is already a challenge.
- Niche and bench complexity. A single pre-formed niche is fast and affordable. A full-height recessed niche with a shelf, or a corner bench built into the waterproofing plane, adds labor and material cost but makes daily use significantly better. We price these as line items so you can decide which matters more.
- Valve and fixture grade. A pressure-balanced single-handle valve is the standard, safe workhorse. Stepping up to a thermostatic valve with volume control and a handshower or body sprays adds $400 to $1,200 in fixture cost plus the plumbing rough-in complexity. In a Marco home where multiple family members use the shower daily, a thermostatic valve that holds temperature steady when someone flushes a toilet is worth the upgrade.
What Walk-In Showers & Shower Remodeling Costs in Marco, FL
We price walk-in shower replacements from $9,000 to $28,000, with the bulk of our Marco work falling between $12,000 and $18,000 for a standard tile shower with a framed glass enclosure, no drain relocation, and mid-grade fixtures. Add $2,000 to $4,000 if the drain moves, $1,500 to $3,000 for frameless glass, and $3,000 to $6,000 if we’re rebuilding rotted framing or subfloor discovered during demo.
The five variables that push a job toward the high or low end are:
Drain location. Keeping the drain where it is saves the slab-cutting, pipe-sleeving, and repour. Moving it across the shower footprint is the single largest cost adder on a Marco slab home, and it’s the first thing we look for during the site visit.
Existing water damage. In a Deltona-era home, a shower that’s been leaking behind the tile for years can leave you with rotted bottom plates, compromised drywall, or rusted-out cast-iron trap arms. We won’t know the full scope until the walls come down, but we budget a contingency line for it and walk you through it at demo if we find it.
Material grade. Off-the-shelf subway tile and a builder-grade valve keep the materials bill low. Handmade tile, a thermostatic valve system, and a frameless heavy-glass enclosure push the materials number up fast. We spec everything line by line so you see exactly where the dollars land and can adjust without guessing.
Permit and flood-compliance scope. A straightforward like-for-like shower swap with no structural changes typically clears the permit desk without triggering additional reviews. If your shower remodel is part of a larger Bathroom Remodeling in Marco project that crosses Collier County’s substantial-improvement threshold, the entire scope shifts into flood-compliance territory, and we’ll have that conversation before any work begins.
Access and logistics. Second-floor condos, elevated homes with exterior stair-only access, and tight Marco Island lots with limited staging space add labor hours for material handling and dust containment. We account for it in the estimate so there’s no change-order surprise.
Every estimate we write is a fixed-price, line-item document, not a ballpark. The number you see is the number you pay, backed by our 730-Day Done Right Promise: if it’s not done right, we make it right.
What Marco Homes Specifically Do to This Job
The Deltona-era concrete block ranch homes that make up a big slice of Marco’s housing stock share a common bathroom layout: the shower sits in an interior alcove, boxed on three sides by block walls, with the drain embedded in the slab. That setup is fine when it works, but when the drain needs to move, or when the cast-iron trap has rusted through from decades of salt-adjacent humidity, you’re cutting concrete. Our Bathroom Remodeling crew does it routinely, and we schedule the saw-cutting as day-one work so the rest of the job doesn’t stall.
On newer Marco builds - elevated homes on pilings or stem walls with wood-framed subfloors - the plumbing chase is accessible from below, which speeds up drain relocation and reduces cost compared to typical Asphalt Driveways & Resurfacing in Marco slab work. But those homes come with their own requirement: all penetrations through the floor assembly have to maintain the floodplain seal. We spec gasketed drain assemblies and seal every fastener penetration to meet the Collier County inspection standard, and we coordinate the permit close-out with the building department so you’re not chasing paper later.
Permitting a shower remodel in Marco is generally straightforward if the scope stays within the existing shower footprint and doesn’t alter the structure. Collier County requires a plumbing permit for drain and valve work, and the inspection sequence runs rough-in, pan flood test, and final. We handle all three and stay on site for every inspection. If the shower is part of a larger project - some Roof Replacement & Installation in Marco jobs lead to interior renovation talks, and we’ve had homeowners combine a shower remodel with the post-roof dry-in timing - we coordinate the permit scopes so nothing trips a surprise plan review.
Salt air is the silent variable. We use corrosion-resistant fasteners, stainless steel grab-bar anchors, and silicone sealant rated for coastal exposure on every Marco shower job, just as we do with Aluminum Fence - Marco installations. A shower built with inland-spec materials will show rust and grout failure within a few years here. We’ve torn out enough of them to know the difference.

Frequently Asked Questions About Walk-In Showers & Shower Remodeling in Marco
Five to seven working days for a full tile shower replacement, assuming no major framing or slab surprises. A solid-surface system can finish in three to four days. The permit inspection sequence - rough-in, flood test, final - adds a day or two of scheduling buffer, which we build into the timeline up front.
Yes, if you’re touching the drain, valve, or any plumbing inside the wall. Collier County requires a plumbing permit, and we pull it as part of the job. A cosmetic refresh that swaps tile and trim without plumbing changes may not require one, but nearly every full walk-in shower remodel we do in Marco includes valve or drain work that triggers a permit.
In most Marco homes, yes. If the existing drain location works for your new shower layout and the valve is in good condition at the right height, we can work with the existing rough-in and save the slab-cutting cost. During the site visit we’ll tell you whether keeping it where it is makes sense, or whether moving it solves a layout problem worth the expense.
Drain relocation. Saw-cutting a concrete slab, sleeving the pipe, and repouring around it adds $2,000 to $4,000 depending on how far the drain moves and what’s in the slab path. After that, frameless glass and high-end tile are the next biggest levers. We price everything as a line item so you can see each decision’s dollar impact before you commit.
