Madeira Beach packs a lot of housing onto a narrow barrier island between the Gulf and Boca Ciega Bay, and few of those bathrooms were designed for the way owners live today. The 1950s beach cottages and canal homes near John's Pass still carry small original baths, fiberglass tub-and-shower combos, cultured-marble tops, and dated tile. The canal-home neighborhoods like Crystal Island sit on the Boca Ciega Bay side, where decades of humidity and salt air work behind the tile. And the beachfront condos along Gulf Boulevard bring their own puzzle: association approvals, shared plumbing stacks, and slab construction that shapes what a shower can become.
CMK Construction has been transforming Madeira Beach bathrooms for over two decades. We know the finishes that survive Florida humidity and Gulf salt air this close to the water, the tub-to-shower conversions and curbless entries that make a bath safer to age in, the logistics of working inside a condo building, and the permit process through the City of Madeira Beach Building Department and Pinellas County. From a simple tub-to-shower conversion to a full spa master suite, we've done it all.
From a single shower update to a full primary suite, CMK handles every part of your bathroom remodel.
Custom tiled showers with frameless glass, niches, benches, and curbless wet rooms, every one waterproofed to outlast the house.

Bathrooms fail faster on a barrier island. Florida humidity works on every grout line and Gulf salt air corrodes low-grade fixtures, and the 1950s beach cottages near John's Pass have usually been sealed up behind original tile for decades. The canal homes in Crystal Island take on the same humidity from the Boca Ciega Bay side, while the beachfront condos along Gulf Boulevard add association approvals, shared plumbing stacks, and slab construction to the equation.
CMK plans for all of it before demo. On the island, that means finishes built for humidity and salt air, ventilation sized for the room, and waterproofing done right the first time while unused fiberglass tub-and-shower combos become walk-in showers. For the retirees and second-home owners staying put, it means curbless entries, grab bars, and bench seating that keep a bath usable for the long term. In the Gulf-front homes and canal properties around Crystal Island and John's Pass, it usually means a full spa master: freestanding tub, oversized shower, double vanity.
Every bathroom CMK remodels gets Schluter waterproofing under every tile. It's a lifetime-warrantied membrane that many contractors skip, and it's the single biggest difference between a bathroom that lasts 30 years and one that starts leaking in 10, especially this close to the Gulf.
Madeira Beach homeowners have choices. Here's why thousands of Tampa Bay families have chosen CMK, and why they refer us to their neighbors.

Real reviews from Madeira Beach bathroom remodel clients across Gulf Boulevard, Crystal Island, Boca Ciega Bay, John's Pass, and the Gulf-front condos.
"Complete gut of the master bath in our Gulf Boulevard home. CMK pulled the City of Madeira Beach permit, scheduled every inspection, and passed each one the first time. The oversized walk-in shower with frameless glass made the whole house feel newer."
"Tub-to-shower conversion in our Crystal Island cottage, finished in four weeks like they promised. Our project manager Nick explained the Schluter waterproofing before any tile went up, and the new shower looks like it came out of a magazine."
"Our canal home off Boca Ciega Bay had a bathroom that had taken on years of Florida humidity. CMK rebuilt it with Schluter waterproofing, a floating vanity, and a curbless shower with a linear drain. The room feels twice as big and finally holds up to the salt air."
"Spa master bath in our home near John's Pass. Freestanding tub, oversized walk-in shower, double vanity. The showroom visit made every selection easy, and the finished room is the best part of the house now."
"Gulf-front condo bathroom on Gulf Boulevard, full remodel. CMK handled the association approvals, worked around the building's plumbing stack, and recommended fixtures and finishes that hold up to the salt air off the Gulf. Frameless glass, new tile floor to ceiling, and not a single surprise on the invoice."
"We remodeled our bathroom in our Crystal Island home so we can stay in this house as we age. CMK converted the old tub to a curbless walk-in shower with a bench, anchored the grab bars into solid blocking, and it looks like a spa, not a hospital. Could not be happier."
Bathrooms are the single most common place a remodel goes wrong years after it finishes, almost always because of how the shower was waterproofed. These are the questions worth asking any Madeira Beach contractor before signing a contract, with any company, not just CMK.
Why it matters: This is the single biggest difference between a 5-year bathroom and a 30-year bathroom. Madeira Beach's Florida humidity and Gulf salt air destroy low-grade waterproofing.
Good answer: A name-brand sheet membrane system (Schluter-KERDI, Wedi, or equivalent) installed under every tile, with the manufacturer's lifetime warranty in writing.
Why it matters: Unlicensed contractors can void your homeowner's insurance and leave you personally liable for code violations.
Good answer: A state-issued CGC license number on every estimate, plus a CFC plumbing license on file. CMK is CGC 1516665 with plumbing under CFC 1430533.
Why it matters: Homeowner-pulled permits make you personally liable for code compliance, not the contractor.
Good answer: The contractor pulls every City of Madeira Beach (or Pinellas County) permit, handles coastal and flood-zone review where it applies, and schedules every inspection at no extra charge.
Why it matters: Without a named project manager, you'll spend the build chasing updates from a salesperson who's already moved on.
Good answer: A named PM, a real person you can call, who visits the job multiple times per week and communicates daily.
Why it matters: "We stand behind our work" is not a warranty. Get it in writing, especially on waterproofing.
Good answer: A written warranty on workmanship and materials, plus a separate manufacturer warranty on the waterproofing membrane. CMK's Peace of Mind Warranty covers both.
Why it matters: Tile and stone look completely different in catalog photos than they do in real samples under real lighting.
Good answer: A real showroom where you handle tile samples, vanity finishes, fixtures, and shower glass before anything is ordered. The 4,000 sq ft CMK Design Studio on W. Hillsborough Ave is open to active clients.
