AfterFast, Reliable Bathroom Remodeling Across Bay Harbor Islands
A full bathroom remodel in Bay Harbor Islands typically runs $9,000 – $28,000, and the number that matters most is the one written down before demo starts. We’re Penhallow Remodeling, and we’ve worked inside enough of these mid-century concrete buildings to know what’s behind the tile before we open the wall. Call (936) 259-2607 for a free estimate that includes a written price and a written guarantee.
Bay Harbor Islands isn’t like the mainland. You’re on two man-made islands with Biscayne Bay on every side, and that changes how a bathroom gets remodeled. The salt air reaches every wall, the water table sits at grade, and the concrete in buildings from the 1960s and 70s often hides corrosion nobody planned for. We schedule our Bathroom Remodeling crews around those realities, not around a generic punch list. Whether you’re in a poured-concrete condo off 96th Street or a newer townhome near the Broad Causeway, we’ll give you a real arrival window and a price that doesn’t change at the door.
Trevor Nash runs our crew, and he’d tell you the same thing he tells every Bay Harbor Islands homeowner: we write the price down, we show up when we said we would, and if it’s not done right inside a year, we come back and make it right. That’s the 365-Day Done Right Promise, in writing, on every project.
Why Penhallow Remodeling Is Bay Harbor Islands’s Preferred Bathroom Remodeling Company
Homeowners across Bay Harbor Islands call us because we answer the phone. A live person picks up 24/7, not a voicemail tree. That matters when you’re coordinating a bathroom remodel around a condo board’s milestone inspection schedule or a building manager’s access window. We know the buildings here; we know which ones have post-tensioned slabs and which have cast-in-place concrete, and we plan accordingly.
Every technician who walks into your home is background-checked and arrives in uniform. You’ll know exactly who’s there, and so will your neighbors. Our Bay Harbor Islands customers tell us that’s the part they didn’t get from their last contractor: a clear sense of who was doing the work and what it would cost before anything got torn out.
Dispatch for Bay Harbor Islands is coordinated from our Miami office, but the crews working on your bathroom live and work in this market. They understand the building stock, the permitting flow through Miami-Dade County, and the structural realities of island construction. That local knowledge means fewer surprises and faster turnaround on the parts of the job that can’t be scheduled around a supply chain delay.
Shower Remodel in Bay Harbor Islands
A Shower Remodel in Bay Harbor Islands typically costs $3,000 – $8,500 depending on the shower size, the tile you select, and whether hidden concrete work shows up once the old pan is pulled. In these island buildings, we regularly find corroded drain assemblies and failed waterproofing at the rough-in stage, because the water table here sits at grade and chloride from the bay is in everything. That means a shower remodel on these islands frequently needs a specialized membrane detail and, in some buildings, a structural consult before new tile goes back on.
Hidden Slab Conditions
Before we set a single tile, we check what’s under the shower pan. In Bay Harbor Islands’ mid-century concrete buildings, the subfloor can hide chloride-induced rebar corrosion that a mainland contractor would never think to look for. We pull core samples when needed and coordinate with a licensed structural engineer if the slab needs remediation. It’s not overkill; it’s what this island requires.
Frameless Glass and Custom Tile
Once the structure is sound, we get to the part you actually see. Frameless glass shower enclosures, full-height tile, custom niches, and handheld fixtures are standard on high-end Bay Harbor Islands remodels. We install Kohler and Moen fixtures and work with your designer on the finish schedule so the glass and tile arrive in the right sequence.
Tub to Shower Conversion in Bay Harbor Islands
A Tub to Shower Conversion in Bay Harbor Islands runs $3,500 – $10,000, and it’s the most popular bathroom project we do on these islands. Most of the older condos here were built with one tub in the guest bath, and homeowners want that footprint turned into a walk-in shower with a low-profile base and grab-bar blocking. In a 1965 building, that conversion often means relocating the drain and discovering the slab isn’t as predictable as the floor plan suggests.
Working Around Post-Tensioned Slabs
Many Bay Harbor Islands buildings use post-tensioned concrete slabs, which means you can’t simply cut into the floor to move a drain without knowing where the cables run. We scan the slab before any cutting. If we find corrosion or failed waterproofing during the rough-in, we flag it in writing as a potential change order before the work proceeds, so the number doesn’t surprise you later.
Walk-In Showers for Aging in Place
A tub-to-shower conversion is also the right move for homeowners who plan to stay in their Bay Harbor Islands condo as they get older. A zero-threshold entry, solid blocking for future grab bars, and slip-resistant tile make the bath safer without making it look institutional. We’ll talk through the accessibility details without upselling you on anything you don’t need.
Trusted Brands We Service in Bay Harbor Islands
We install and service materials from brands our Bay Harbor Islands customers actually ask for: Cambria quartz, Silestone and Caesarstone countertops, KraftMaid and Wellborn cabinetry, Kohler and Moen fixtures, and Delta faucets. When you choose Cambria, you get its lifetime warranty on top of ours, which matters on an island where salt air is hard on finishes. Our team orders from these manufacturers regularly, which helps us coordinate long-lead items and keep your Bay Harbor Islands project moving when a slab or a vanity cabinet takes eight to sixteen weeks to arrive. We’ll tell you the lead time before we order, and we’ll write the price down before the first fixture is purchased.
Common Bathroom Remodeling Problems We See in Bay Harbor Islands Homes
- Corroded rebar under the subfloor: The bay surrounds these islands on all sides, so chloride-laden air penetrates from every direction, not just a prevailing sea-breeze side. We’ve opened bathroom walls in these mid-century buildings and found structural corrosion that turned a simple valve relocation into a coordinated slab repair.
- Hydrostatic uplift at drain penetrations: Because the water table sits at grade, shower pan and drain penetrations often leak into the slab. This requires specialized membrane details and, during construction, continuous dewatering of any below-grade work.
- Long-lead designer finishes delaying the calendar: Cambria, Silestone, and Caesarstone slabs plus KraftMaid and Wellborn cabinetry frequently run 8 – 16 weeks. Contractors who schedule labor before confirming those lead times blow the calendar and eat storage costs; we sequence the project around the materials, not the other way around.
- Failed waterproofing membranes in aging walls: Many of these buildings have original membranes from the 1960s and 70s that have simply given out. If the waterproofing is compromised behind the tile, any new finish work will fail quickly, which is why we inspect and replace the substrate (the moisture-resistant layer behind your tile) before setting anything new.

The size of the bathroom, the cabinet line and countertop material you choose, whether we’re moving plumbing, and whether hidden slab or waterproofing work shows up once we open the floor or wall.

FAQs About Bathroom Remodeling in Bay Harbor Islands
Yes, most bathroom remodels in Bay Harbor Islands that involve plumbing, electrical, or structural changes require a permit through Miami-Dade County’s building department, and some condos need board approval before work begins. We pull the permits for you, and we coordinate the inspections. In buildings subject to milestone inspections, we’ll coordinate our work with the building’s structural engineer so the bathroom remodel doesn’t conflict with any required remediation. Call (936) 259-2607 and we’ll tell you exactly what your building will need.
The chloride in Bay Harbor Islands’ air accelerates corrosion on metal rough-in plumbing and any exposed rebar, which is why we use marine-grade or corrosion-resistant materials wherever the building’s structure is involved. For finishes, we recommend quartz over natural stone for surfaces that will face constant humidity, and we specify corrosion-resistant fixtures. The island setting means every wall behaves like an ocean-facing wall, so material selection here isn’t optional. Call (936) 259-2607 and we’ll walk you through what holds up.
Custom cabinetry from KraftMaid or Wellborn and quartz slabs from Cambria, Silestone, or Caesarstone frequently run 8 – 16 weeks from order to delivery. The schedule isn’t set by labor; it’s set by the lead time on those finishes. We write the price down before ordering, confirm delivery windows with the manufacturer, and sequence the demo and rough-in work around the materials so your bathroom isn’t sitting open longer than it needs to be. Call (936) 259-2607 with your finish selections and we’ll give you a date range.
Yes, and it happens more often in Bay Harbor Islands than in any inland or non-island community. In a 1965 poured-concrete condo off 96th Street, our crew opened a bathroom wall to relocate a shower valve and found fully corroded rebar in the post-tensioned slab beneath the subfloor. We brought in a licensed structural engineer, documented the chloride-induced spalling with core samples, and coordinated a slab repair with the building’s milestone inspection consultant before rough-in. The final scope cost nearly triple the original estimate, but because we fixed the price in writing and flagged the hidden condition as a potential change order from day one, there were no surprises. Call (936) 259-2607 if you suspect this in your building.
We write the base price for the work you can see, and we itemize potential change orders for the hidden conditions common on Bay Harbor Islands: slab corrosion, failed waterproofing, and hydrostatic uplift at drain penetrations. If we open the wall and find corrosion, the change order is already described in writing and priced at a unit rate you agreed to before demo began. The number on day one stays the number on the invoice unless a documented hidden condition triggers a pre-agreed change. Call (936) 259-2607 and we’ll show you exactly what that looks like in a real estimate.
