Tampa's heat and humidity are unforgiving on bathrooms that weren't properly waterproofed. A grout line that looks fine in February starts failing by August. A tub surround caulked instead of properly waterproofed is how mold grows inside the wall for three years before a homeowner notices. A cast-iron tub in a 1925 Seminole Heights bungalow is original to the house and nearly impossible to remove without a professional who has done it before. The problem is not the bathroom age. It is whether the remodeler understood what Tampa's climate and housing stock actually demand.
CMK Construction waterproofs every wet surface with a Schluter system — Kerdi-Board, Ditra, Kerdi-Band — under every tile, on every wall, around every fixture. We have done this for over twenty years, in Seminole Heights bungalows with galvanized plumbing we reroute before demo, in Carrollwood ranches where the tub alcove shares a wall with the bedroom closet, and in Tampa Palms estates where the primary bathroom is a second kitchen's worth of square footage. Every scope, same waterproofing standard. Every project, same licensed in-house plumbing team under CFC 1430533.
Real bathroom remodels across Tampa — a 1927 Seminole Heights bungalow bath restoration, a Carrollwood tub-to-walk-in-shower conversion, and a full primary bath gut renovation in Tampa Palms.

See Custom Bathroom Designs →Seminole Heights, Tampa Heights, and Riverside Heights bungalows often have original cast-iron tubs worth keeping, original mosaic hex floors worth refinishing, and galvanized plumbing ready to replace. CMK preserves what's worth keeping and replaces what isn't — with Schluter waterproofing behind every new tile and licensed plumbing throughout.
Explore Shower Options →Tampa homeowners aging in place, recovering from injury, or adapting for a family member increasingly choose to convert a tub-only bathroom to a spacious walk-in shower with grab bars, a bench, and a curbless threshold. CMK designs these in coordination with your needs and handles the City of Tampa or Hillsborough County permit start to finish.

The most common bathroom remodel failure mode in Tampa is not design — it is waterproofing. A contractor who tiles over cement board without a membrane system is building a water damage problem that shows up in two to five years. The grout goes first. Then the caulk at the corners. Then the tile starts moving. Then there is mold inside the wall. In Tampa's climate, that timeline compresses because the humidity never fully drops and the temperature swings between the air-conditioned interior and the outdoor heat stress every surface in the shower and tub area year-round.
CMK uses the Schluter waterproofing system on every bathroom we build. Kerdi-Board on the shower walls, Ditra under the floor tile, Kerdi-Band at every seam and corner, Kerdi-Drain at the base. Not as an upgrade. As the standard, on every job, regardless of budget. Our in-house licensed plumbers (CFC 1430533) rough in the plumbing before demo is over. Our Registered Electrical Contractor (ER13016498) handles the exhaust fan, the heated floor, and the lighting. Every City of Tampa or Hillsborough County permit is ours from start to finish.

Real reviews from Tampa bathroom remodel clients across Seminole Heights, Carrollwood, Tampa Palms, Westchase, Tampa Heights, and New Tampa.
"Our 1927 Seminole Heights bungalow had the original cast-iron tub we wanted to keep. CMK cleaned and re-glazed it, replaced all the galvanized plumbing behind the wall, re-tiled the surround with period-correct subway tile, and used the Schluter waterproofing we specifically asked about after reading reviews. Davis was our PM and was at the house every day."
"We had a builder-grade tub and shower combo in our Carrollwood master bath from 1985. CMK converted the tub to a walk-in shower with a bench and a rain head, double vanity in custom shaker, and large-format porcelain tile floor to ceiling. The Schluter system was part of the scope from day one. Completed in five weeks exactly as promised."
"Primary bath in our Tampa Palms home was overdue for a complete gut. CMK gave us a frameless glass walk-in shower with a marble-look porcelain tile, a soaking tub as a feature piece, his-and-hers vanities with quartz tops, and heated floors throughout. Aimee at the showroom helped us get the design right. Best money we've spent on this house."
"We needed a curbless walk-in shower with grab bars and a fold-down bench for my father-in-law who moved in with us. CMK designed it around the occupational therapist's recommendations, pulled the City of Tampa permit, widened the doorway, and finished the whole job in three weeks. Sahara kept us on schedule and the tile work is exceptional."
"Tampa Heights bungalow bathroom, original tile from the 1940s and galvanized pipes. We kept the hex floor — CMK refinished it — and rebuilt everything else with Schluter and new plumbing. Three contractors said they couldn't keep the hex. CMK said yes, matched the grout color perfectly, and the floor looks original. Zach ran a very clean jobsite."
"New Tampa master bath gut renovation. Frameless glass shower with a huge bench and niche, soaking tub, double vanity, the works. CMK handled the Hillsborough County permit, the plumbing reroute through the slab, the drywall, the tile, everything. Carlos was our PM and I never had to chase a single update — he texted me every morning before 8am."
Most Tampa homeowners only remodel a bathroom once or twice in their lives. These are the questions worth asking before signing any contract, with any company, not just CMK.
Why it matters: In Tampa's climate, a bathroom without a continuous waterproofing membrane behind the tile will develop mold and water damage within a few years. Caulk and cement board are not a waterproofing system.
Good answer: A named, professional waterproofing system (like Schluter Kerdi) installed under every tile, on every wet surface, by the contractor's own crew.
Why it matters: Subcontractor plumbers shift between jobs and aren't accountable to the contractor's warranty or schedule.
Good answer: In-house, licensed plumbers (Florida CFC license) who work exclusively on the contractor's projects from rough-in to final trim.
Why it matters: Homeowner-pulled permits make you personally liable for code compliance, not the contractor.
Good answer: The contractor pulls every City of Tampa or Hillsborough County permit and schedules every inspection at no extra charge.
Why it matters: Without a named project manager, you spend the build chasing updates from a salesperson who has already moved on to the next sale.
Good answer: A named PM (a real person, not a phone tree) who visits the job multiple times per week and contacts you with daily updates.
Why it matters: Unlicensed contractors can void your homeowner's insurance and leave you liable for code violations on a bathroom plumbing or electrical project.
Good answer: A Florida CGC license number on the estimate, plus general liability and workers' comp certificates readily available.
Why it matters: Small tile samples and catalog photos look very different at full-room scale and in different light. Most homeowners who commit to materials without seeing them in person regret at least one selection.
Good answer: A real showroom with full tile displays, vanity mockups, and fixture selections where you can touch and approve everything before ordering.
Why it matters: Seminole Heights bungalows, Tampa Heights craftsmans, and 1950s Carrollwood ranches have galvanized plumbing, original cast-iron fixtures, and vintage tile that need a contractor familiar with them.
Good answer: Local references in Seminole Heights or Tampa Heights the contractor can connect you with on request.
Why it matters: "We stand behind our work" is not a warranty. Waterproofing failures in particular need a contractor willing to come back and make it right.
Good answer: A written, named warranty covering both workmanship and materials for at least one year, with a clear process for making warranty claims.
