Fast, Reliable Bathroom Remodeling Across Miami
Bathroom remodeling in Miami typically runs $9,000-$28,000 for a full renovation, with most projects completed in 3-6 weeks once permits clear. We’re Groundwork Construction Co. of South Florida, and our crews work Miami-Dade County regularly - from Coral Gables up through Allapattah and down to Coconut Grove. If you’re staring at corroded fixtures in a 1960s CBS bathroom or trying to figure out why your contractor’s “Florida-approved” window just failed inspection, we can help. Call (844) 665-0162 for a free estimate.
Miami’s older housing stock isn’t like Fort Lauderdale’s or Palm Beach’s. The concrete block homes built from the 1940s through the 1970s in neighborhoods like Flagami (33126) and Overtown (33127) have specific failure modes: corroded rebar from salt-air exposure, original plumbing undersized by modern standards, and jalousie windows that no longer meet code. We’ve remodeled bathrooms in these homes. We know what the county inspector will flag before they even walk in.
Why Groundwork Construction Co. of South Florida Is Miami’s Preferred Bathroom Remodeling Company
Raymond Estevez built this company on the idea that homeowners shouldn’t need three different contractors to handle related projects. One contractor, every phase. When we remodel your bathroom in Miami, we’re also the same team that can replace your roof, install impact windows, or build an ADU in the backyard - all with the same material rigor and permit discipline.
Our crews know Miami-Dade’s Notice of Acceptance system inside and out. Most out-of-county contractors don’t. They bring products approved under Florida’s statewide building code, then watch their permits get rejected because Miami-Dade requires its own hurricane-simulation testing for every window, door, and structural fastener. We’ve seen it happen on jobs we were called in to fix. You choose the brand, we handle the build - and we make sure every fixture carries the right NOA documentation before demolition starts.
We respond to Miami inquiries within one business day, and most estimates are scheduled within 48 hours. Our project managers live in South Florida, not dispatched from some regional call center. They know that traffic on the Dolphin Expressway can add 40 minutes to a material delivery, or that crane scheduling in Brickell requires city coordination weeks ahead. That local fluency saves you time and rework.
Our Bathroom Remodeling Services in Miami
Full Bathroom Remodeling
A full bathroom remodel in Miami means dealing with legacy construction that wasn’t built for modern fixtures. In CBS homes through Little Havana and Brownsville, we’ve torn out original 1950s bathrooms and found galvanized supply lines, cast-iron drains with active corrosion, and slab conditions compromised by hydrostatic pressure from the shallow water table. Our full remodels address the structure behind the tile, not just the surface. We handle demolition, rough plumbing, electrical, waterproofing, tile, fixtures, and final inspection - one accountable team from start to finish.
Walk-In Shower Installation
Walk-in shower installation is our most requested bathroom upgrade in Miami, especially in aging condos and single-family homes where climbing over a tub threshold has become a daily frustration. A typical walk-in shower in Miami runs $4,500-$12,000 depending on size, tile selection, and whether we need to relocate drains. We install curbless and low-threshold designs with proper slope and drainage, using Miami-Dade NOA-approved glass enclosures and waterproofing systems. In a 1950s CBS home near Flagami’s 33126, our crew replaced a failing one-piece shower unit whose original valve was seized and corroded. We sourced a Miami-Dade NOA-approved Moen valve, retrofitted the drain to handle hydrostatic pressure from the shallow water table, and replaced the original jalousie window with an impact-rated unit that passed county inspection on the first try.
Tub-to-Shower Conversion
Converting a tub to a shower in Miami isn’t always straightforward. Many older homes have tubs set in mortar beds on slabs with inadequate drainage fall, or supply lines positioned for tub fillers that won’t work with modern shower valves. Our tub-to-shower conversions run $3,500-$10,000 and include full assessment of your existing plumbing, proper waterproofing to Miami-Dade standards, and installation of NOA-approved fixtures. If your home is in a flood-prone zone like parts of Allapattah or Coconut Grove, we also evaluate whether the conversion should include a linear drain or other features that handle the water table conditions specific to your lot.
Vanities, Tile & Fixtures
Vanity installation in Miami starts around $800 and ranges to $3,000 depending on size, material, and whether we’re relocating plumbing. We work with KraftMaid, Wellborn, and other cabinet lines that offer moisture-resistant construction - critical in Miami’s humidity. For tile, we specify porcelain or ceramic with proper waterproofing membrane behind it, never direct-to-drywall installation. Our countertop selections include Cambria, Silestone, and Caesarstone - three of the most recognized engineered quartz brands in residential construction - giving you options that resist staining and hold up to daily use without the maintenance of natural stone.
Small Bathroom Remodels
Small bathrooms are common in Miami’s older housing stock, especially in duplexes and apartment conversions through Overtown and Brownsville. A small bathroom remodel runs $5,000-$12,000 and requires smart space planning: wall-hung vanities, pocket or sliding doors, recessed niches, and large-format tile that minimizes grout lines. We’ve remodeled bathrooms as small as 25 square feet that still include full showers, proper ventilation, and code-compliant electrical. Built to spec, not to convenience.

Trusted Brands We Service in Miami
Groundwork works with 50+ recognized industry brands across cabinetry, countertops, roofing, windows, doors, fencing, hardscaping, and ADU construction. For bathroom remodeling in Miami, that means you choose from multiple tiers and styles rather than accepting whatever our supplier has in stock. We specify Moen and Delta for plumbing fixtures with verified Miami-Dade NOA approval. Our glass enclosures come from manufacturers with documented hurricane-testing compliance. For homeowners considering future expansion, we also partner with prefab innovators including Mighty Buildings and Boxabl for ADU construction - so your bathroom remodel today can connect to a larger home addition plan tomorrow. We stock common replacement parts locally and coordinate specialty orders through Miami-Dade-compliant suppliers, keeping lead times predictable.
Common Bathroom Remodeling Problems We See in Miami Homes
- NOA-noncompliant fixtures causing permit rejection. A contractor installs a shower valve or window approved only under Florida’s statewide code, but without Miami-Dade’s separate NOA. The inspector rejects it. Everything comes back out. We verify NOA status before ordering anything.
- Corroded legacy plumbing discovered mid-demolition. Tearing out a one-piece fiberglass shower from the 1960s reveals supply lines and drains too corroded or undersized for modern fixtures. Emergency rerouting under a slab that’s already waterlogged from the shallow limestone water table adds days and thousands to the project.
- Failed waterproofing from below-grade moisture. Applying conventional waterproofing or below-grade drainage without accounting for Miami’s hydrostatic pressure leads to persistent moisture intrusion and mold behind new tile within months. We specify membrane systems rated for active water pressure, not just surface splash.
- Original jalousie windows that can’t be reused. Those louvered aluminum windows in older Miami bathrooms don’t meet current impact or ventilation codes. Replacement requires proper Miami-Dade NOA documentation and often structural reframing - something we assess during initial estimate, not as a change order.
Pricing for Bathroom Remodeling in Miami, FL
Bathroom remodeling in Miami carries specific cost drivers you won’t find in other markets: Miami-Dade NOA-compliant fixtures often cost 15-25% more than statewide-approved equivalents, permit documentation requires additional labor, and hydrostatic waterproofing adds material expense. Here’s what typical projects run in Miami’s current market:
| Service | Price Range in Miami |
|---|---|
| Full Bathroom Remodel | $10,620-$33,040 |
| Walk-In Shower Installation | $5,310-$14,160 |
| Tub-to-Shower Conversion | $4,130-$11,800 |
| Bathroom Vanity Installation | $945-$3,540 |
| Small Bathroom Remodel | $5,900-$14,160 |
These ranges include Miami-Dade permit fees, NOA-compliant materials, and the waterproofing specifications our climate demands. What pushes a project toward the high end: relocating plumbing, custom tile work, expanding the footprint, or discovering corroded infrastructure behind existing finishes. We price upfront after full site assessment, not with low-ball estimates that balloon later. Call (844) 665-0162 for an exact quote - estimates are free.

FAQs - Bathroom Remodeling in Miami
Miami-Dade County maintains its own Notice of Acceptance product approval system, entirely separate from Florida’s statewide building code, and every shower valve must pass Miami-Dade’s hurricane-simulation testing before legal installation. A valve approved in Broward County one mile north may be code-illegal here. We source only NOA-documented fixtures and include that paperwork with your permit submittal, so inspection passes on the first visit. Call (844) 665-0162 if you’re unsure whether your selected fixtures qualify.
No. One-piece fiberglass units from the 1960s and 1970s are typically cracked, delaminated, or dimensionally incompatible with modern plumbing connections, and the substrate behind them almost always needs remediation for moisture damage. In Miami’s CBS homes, we’ve never encountered a salvageable original unit that met current code. We remove them completely, assess the slab and walls, and install properly waterproofed, NOA-compliant systems. Call (844) 665-0162 for an assessment of your specific bathroom.
Conventional below-grade waterproofing fails in Miami because hydrostatic pressure pushes water upward through porous Miami Limestone, not just inward from surface flooding. We specify bonded membrane systems with drainage composite and, where conditions warrant, sump or pump integration for ground-level bathrooms. This isn’t standard practice elsewhere in Florida, but it’s essential here for preventing mold behind new tile. Every bathroom we remodel in Miami includes this site-specific assessment.
Standard bathroom remodel permits in Miami-Dade typically take 2-4 weeks for initial review, with possible additional cycles if documentation is incomplete. Projects requiring structural assessment, electrical panel upgrades, or NOA verification for specialty fixtures can extend to 6-8 weeks. We submit complete packages with all NOA documentation, engineered drawings when needed, and pre-coordinated inspection schedules to minimize delays. Call (844) 665-0162 to discuss timeline for your specific project.
Walk-in shower conversions make sense for most Miami homeowners who don’t regularly use a tub, especially in aging condos where accessibility matters and in single-family CBS homes where the existing tub plumbing is often corroded. The decision depends on your building type: condos may require association approval and waterproofing that protects units below, while single-family homes allow more flexibility with drainage modifications. We assess both scenarios during your free estimate. Call (844) 665-0162 to discuss whether a tub-to-shower conversion fits your Miami home.
