Bathroom Remodeling
A bathroom is the most demanding room in your house to build well — every surface is wet, the humidity is relentless, and the details hide where you can’t see them. Here’s how we get it right.
A bathroom looks like a small project and behaves like a big one. Behind the tile is plumbing, behind the plumbing is framing, and behind all of it is the one thing that decides whether the room lasts ten years or starts leaking in two: waterproofing. We remodel bathrooms the way we build custom homes — from the substrate out — so the part you admire is backed by the part you never see. As a licensed Florida general contractor, Carapezza handles the design, the permits, the plumbing, and the finish work as one coordinated job across Greater Tampa Bay.
What’s Involved
More than tile and a new vanity.
Most bathroom remodels fall into one of three buckets, and they're very different jobs. A primary or spa bathis the showpiece — a large walk-in shower with multiple heads, a freestanding soaking tub, a double vanity, often a private water closet and a separate dressing area. A guest or hall bath is about smart use of a tighter footprint: durable finishes, good storage, and a layout that works hard. And an accessible, aging-in-place bathis its own discipline — a curbless roll-in shower, blocking framed into the walls for grab bars, a comfort-height vanity, and a layout a walker or wheelchair can actually move through.
Whichever you're building, the work underneath is similar. We're opening walls, often moving plumbing, replacing the shower pan and the substrate, rewiring for lighting and ventilation, waterproofing the wet areas, and then finishing in tile, stone, glass, and cabinetry. The visible part is maybe a third of the job. The other two-thirds is the part that keeps water where it belongs — and that's exactly where corner-cutting remodels go wrong.
Design & Layout
Where the design decisions actually get made.
A bathroom that feels right is mostly about layout, light, and how the fixtures relate to each other — decisions that are cheap to make on paper and expensive to change once tile is set. We design the room before we open a wall.
The biggest move in most remodels is the shower. Homeowners consistently want a bigger walk-in shower and are happy to trade a rarely-used tub to get it — or to keep a freestanding soaking tub as a sculptural piece and build a generous glass shower beside it. Frameless glass enclosures make a small room feel larger; recessed nicheskeep bottles off the floor and have to be planned before waterproofing, not after. A bench, a hand shower on a slide bar, a linear drain — these are layout decisions, and they drive the plumbing and the framing.
Storage and vanities are the other half of the room. This is where a remodel connects to the rest of the house: we frequently pair a bath project with custom cabinetryso the vanity, the linen tower, and the medicine storage are built to the exact dimensions of your space rather than forced to fit a stock box. And the surfaces — the countertop, the tile, the plumbing fixtures, the lighting — are where a bath earns its luxury finishes, the details that make a room feel custom instead of catalog.
Waterproofing & Materials
The part you’ll never see is the part that matters most.
Tile is not waterproof, and grout is not waterproof. The system behind them is. A bathroom remodel lives or dies on the wet-area detailing that gets covered up on day three and either protects your home for decades or quietly fails behind a beautiful wall.
Waterproofed wet areas
A continuous waterproofing membrane behind the tile and a properly built shower pan — bonded, sealed at every seam and corner — so water that gets through the grout has nowhere to go but the drain.
Slope & drainage
The shower floor pitched correctly to the drain, curbless showers sloped to a linear drain, and thresholds detailed so water flows out, not back into the room. Get the slope wrong and the finest tile in the world still puddles.
Niches & benches
Recessed shelves and built-in benches are common leak points because they interrupt the waterproofing plane. We frame and seal them as part of the wet-area system, planned before the membrane goes on.
Glass & enclosures
Frameless glass panels measured and mounted so the enclosure sheds water inward and the surrounding walls and curb are detailed to contain it — the glass is only as good as what it drains onto.
Tile & stone selection
Porcelain, natural stone, large-format tile, mosaic shower floors — each has different sealing, slip, and maintenance needs. We help you choose surfaces that suit how the room is used, not just how it photographs.
Backer & substrate
Cement board or foam backer instead of moisture-prone drywall in wet zones, set on a sound subfloor — the foundation the whole system depends on. The right substrate is invisible and non-negotiable.
The Design-Build Process
How a Carapezza bathroom remodel runs.
- 01
Consultation & design
We walk the space, talk through how the room fails you today and how you want it to work, and develop a layout — shower, vanity, storage, fixtures — before anything is committed.
- 02
Selections & budget
Tile, stone, plumbing fixtures, glass, cabinetry, and lighting are selected against a real budget, and long-lead items are ordered early so they don't stall the schedule.
- 03
Permits & plumbing plan
If we're relocating plumbing or altering structure, we pull the permits and map the drain, vent, and supply work so inspections are built into the schedule, not a surprise.
- 04
Demolition & rough-in
Old finishes come out, the wet area is taken back to a sound substrate, and the plumbing, electrical, and ventilation rough-in goes in — with framed blocking for niches, benches, and any grab bars.
- 05
Waterproofing & inspections
The shower pan and waterproofing membrane are installed and the wet-area system is sealed, with rough-in inspections passed before a single tile is set.
- 06
Tile, stone & finish
Tile and stone are set, glass is measured and installed, the vanity and cabinetry go in, and plumbing and lighting fixtures are trimmed out to the finish standard.
- 07
Final walkthrough
We test the drainage and ventilation, walk the room with you, address the punch list, and close out the permits so the work is documented for the life of the home.
A primary or spa bath typically runs several weeks of active work once it's underway, and a smaller guest bath less — but the honest answer is that schedule depends on the scope, the fixtures, and whether we're relocating plumbing or just refreshing finishes. Long-lead tile, stone, and custom glass can add weeks before we ever start demolition, which is why we order materials early. We scope your specific bath and give you a real, staged timeline rather than a number that sounds good and doesn't hold up.
Plumbing & Permitting
Moving water is where remodels get serious.
The moment a remodel relocates plumbing— moving the toilet, changing where the shower drain lands, converting a tub to a curbless shower — it stops being cosmetic and becomes a permitted construction project. That's a good thing: a permit means the drain slopes are inspected, the venting is right, and the work is documented for the day you sell. We pull the permits, coordinate the inspections, and handle the parts of the job — structural, electrical, mechanical — that a tile-only contractor isn't licensed to touch.
On a slab home, moving a drain can mean cutting and re-pouring concrete; on a raised home it's working in the crawlspace. Either way, this is the difference between a builder and a handyman. We'd rather tell you a wall can't move, or that moving it adds a week, before demolition than discover it mid-project.
Florida Humidity
The climate is the silent design constraint.
Tampa Bay’s humidity doesn’t take a day off. A bathroom that would be fine in Denver can grow mold in Florida, because the air that fogs your mirror condenses inside walls and cabinets where you can’t see it. In our climate, ventilation isn’t a finishing touch — it’s structural.
Ventilation is the make-or-break detail
This is also why material choices matter more here than in a drier climate. Moisture-resistant backer in wet zones, sealed grout and stone, soft-close hardware that survives constant humidity, and finishes chosen to handle Florida air rather than fight it. We've seen what unchecked bathroom moisture does to a home — it's the same problem our restoration crews remediate — so we build the room to prevent it, not to discover it later.
Why a custom builder, not just a tile crew
A lot of companies will set tile. Far fewer will stand behind the framing, the waterproofing, the plumbing, the ventilation, and the finish as one accountable job. That's the difference a licensed general contractor makes: when something has to be right behind the wall, there's one builder responsible for it — not a chain of subs each blaming the last. As a custom-home company, Carapezza brings the same standard to a single bathroom that we bring to a whole house, and the same in-house trades, from cabinetry to finishes. If you're weighing a bath against a larger project, it's worth seeing the rest of our remodeling and renovation work— bathrooms are often the first room people trust us with, and rarely the last.
Questions
Bathroom Remodeling in Tampa Bay — FAQ
How much does a bathroom remodel cost in Tampa Bay?+
It depends heavily on scope. Refinishing a guest bath with the existing layout is a very different number than a primary spa bath with relocated plumbing, a curbless shower, custom cabinetry, and natural stone. We don't publish a flat price because it wouldn't hold up across such different projects — we scope your specific bathroom and give you a real number tied to the choices you actually make.
How long does a bathroom remodel take?+
A primary or spa bath typically runs several weeks of active work once it's underway, and a smaller guest bath less, but long-lead tile, stone, and custom glass can add weeks of lead time before demolition starts. Relocating plumbing or structure adds time too. We scope your bath and give you a realistic, staged schedule rather than a single number that sounds good and doesn't hold.
Why is waterproofing such a big deal?+
Because tile and grout are not waterproof — the system behind them is. A bathroom that isn't properly waterproofed will let water reach the framing and substrate, where it rots wood, grows mold, and eventually fails behind a wall that looks perfectly fine on the surface. Waterproofing is the part you never see and the part that decides whether the remodel lasts ten years or starts leaking in two.
Do I really need extra ventilation in a Florida bathroom?+
Yes, more than almost anywhere else. Tampa Bay's humidity means the moisture from a shower doesn't just clear on its own — it condenses inside walls and cabinets where you can't see it and feeds mold. A correctly sized exhaust fan ducted to the exterior, on a timer that runs after you're done, is one of the highest-value details in a Florida bath. We build it in from the start.
Can you build a curbless, accessible (aging-in-place) bathroom?+
Yes. A roll-in curbless shower, blocking framed into the walls for grab bars, a comfort-height vanity and toilet, and a layout a walker or wheelchair can move through are all things we design and build. Aging-in-place work has its own detailing — especially the curbless shower's slope and waterproofing — and it's worth doing during a remodel rather than retrofitting later.
Does moving the toilet or shower require a permit?+
Generally yes. The moment a remodel relocates plumbing — moving a drain, changing where the shower lands, converting a tub to a curbless shower — it becomes a permitted construction project, which is a good thing: the drain slopes and venting get inspected and the work is documented. We pull the permits and coordinate the inspections as part of the job.
Can I keep my tub, or should I convert it to a shower?+
Either works, and it's a lifestyle question more than a construction one. Many homeowners trade a rarely-used tub for a larger walk-in shower; others keep a freestanding soaking tub as a centerpiece and build a generous glass shower beside it. We'll talk through how you actually use the room and design the layout around that rather than around a default.
What if you find mold or water damage once you open the walls?+
It happens, especially in older Florida bathrooms where the original waterproofing has failed. Because we're a licensed builder with restoration experience, we can address hidden water damage and mold properly as part of the remodel rather than tiling over it. We'll show you what we found and fold the fix into the plan before we close the walls back up.
Will you handle the cabinetry and finishes too, or just the construction?+
All of it. We frequently pair a bath remodel with custom cabinetry built to the exact dimensions of your space, and the tile, stone, fixtures, and lighting that make the room feel custom. As a custom-home builder we keep the whole project — structure, plumbing, waterproofing, cabinetry, and finishes — under one accountable roof rather than handing you off between trades.
