From Old Northeast bungalows to Snell Isle waterfront estates — your St. Pete bathroom has quirks that out-of-town contractors miss. Cast iron under the slab, flood zone plumbing rules, and 100 years of DIY history behind the walls.
Revolution Contractors is headquartered in St. Petersburg with 20+ W-2 carpenters who work in these neighborhoods every week — not a franchise crew learning your city on your dime.
Old Northeast Bungalow
Waterfront Home
Downtown Condo
St. Petersburg's housing stock creates bathroom remodeling challenges you won't find in a national cost guide. Most of the city's core neighborhoods — Old Northeast, Historic Kenwood, Crescent Lake, Euclid-St. Paul's, Old Southeast — were built between 1912 and 1945. The Old Northeast bungalow we're looking at today is 100 years old this year. These are Craftsman bungalows and Mediterranean Revival homes with original 5x7 bathrooms, cast iron drain pipes, and decades of patchwork repairs hidden behind the walls. Per Jeremy's framing on the bathroom-remodel scoping call: “We have a significant amount of 5×7 bathrooms — five feet wide and seven feet deep — about the minimum size for a toilet, vanity, and shower of normal size.”
The waterfront neighborhoods add another layer. Shore Acres, Snell Isle, Venetian Isles, and Coquina Key sit in FEMA AE flood zones, which means bathroom plumbing work can trigger regulatory requirements if your renovation qualifies as a “substantial improvement” — defined as exceeding 50% of your home's market value. Your contractor needs to know these thresholds before they quote, not after they've started demolition.
Downtown St. Pete presents its own constraints. Condo bathrooms in concrete high-rises can't move plumbing stacks — the pipes run through shared structural walls and floors. Ceiling lighting in concrete structures often requires a sleeper system (a secondary framework attached to the concrete ceiling to run electrical). Your remodel options depend on the building's construction, not just your design preferences.
Revolution has renovated bathrooms in bungalows built in 1922, waterfront homes in AE flood zones, and downtown condos with HOA boards that require contractor pre-approval. That range of experience is why 70% of our revenue comes from repeat and referral clients — homeowners who've seen us navigate their specific situation and come back when the next room needs attention.
The majority of bathrooms in Old Northeast, Kenwood, Crescent Heights, and Euclid-St. Paul's have original cast iron drain pipes that are 50–100 years old. Cast iron corrodes from the inside out — your pipes can look fine externally while the interior is scaling shut.
Revolution scopes every bathroom's pipes with a camera before quoting ($100–$300 from a plumber). If replacement is needed, that adds $10,000–$20,000 to the project, but discovering it during demolition is far worse than knowing upfront.
“On any remodel of any size, that cast iron gets replaced because the best time is now while walls are open. There's nothing wrong with cast iron if it's in great shape — it's strong when new — but 50 years of Drano and high-pH solvents cause rust and cracking. We almost always get a camera down the pipes to know what we're dealing with and tell the story to homeowners.” — Jeremy Bonnewell, Co-Owner
If your home is in Shore Acres, Snell Isle, or another AE/VE flood zone, a bathroom remodel can trigger FEMA substantial improvement rules. When total renovation costs exceed 50% of your home's pre-improvement market value, the entire structure may need to be brought into compliance with current flood elevation requirements.
This affects plumbing that runs below the base flood elevation (BFE — the height that floodwaters are expected to reach during a 100-year flood). Your contractor needs to calculate the substantial improvement threshold before pulling permits, not after.
Bathrooms in locally designated historic districts (Granada Terrace, the hexblock districts in Old Southeast, sections of Kenwood on the National Register) may require a Certificate of Appropriateness for exterior changes that affect the home's character.
Interior bathroom work typically doesn't trigger review, but if your remodel includes a bathroom addition that changes the home's footprint or roofline, the Historic Preservation Board gets involved. Revolution has navigated these reviews on multiple projects.
Many Kenwood and Old Northeast bungalows have exactly one bathroom. When you remodel your only bathroom, you need a relocation plan — you can't live without a functioning toilet for 4–14 weeks.
Revolution builds this into the project schedule from the start: discussing temporary living arrangements, timing the work to minimize displacement, and fast-tracking critical milestones like the toilet reconnection so your home becomes livable again as quickly as possible.
Walk your bathroom, evaluate the existing plumbing stack and drain locations, check floor joist direction (critical for drain relocation), and determine scope: cosmetic refresh or full gut. For pre-1970s homes, we recommend a camera scope of the cast iron pipes. In flood zones, we calculate the substantial improvement threshold.
Layout with a designer or vendor-assisted design, tile and fixture selection, cabinetry choices. For downtown condos, we assess what's structurally possible given the building's concrete construction. Budget conversations happen during design — not after you've fallen in love with selections outside your range.
Plumbing and electrical permits through the City of St. Petersburg. Shower pan inspection is bathroom-specific. Cosmetic work without system changes doesn't require permits. For historic district properties, we coordinate any necessary Certificate of Appropriateness applications in parallel.
Demolition, rough-in plumbing and electrical, Schluter waterproofing (lifetime warranty), tile, glass, vanities, paint, and fixtures. Your weekly budget report shows exactly where the money went. Revolution's in-house carpenters handle tile work, waterproofing, and finish carpentry from start to punch list.

Late-career owners of $750K+ St. Pete homes who have been through one fixed-bid renovation and rejected the change-order shell game. They want open-book T&M, weekly budget reports, and a single point of accountability — not a contractor padding every line item to cover risk.
Affluent downtown condo owners who don't want to spend evenings on HOA approval packets. Elevator reservations, freight schedules, noise windows — Revolution handles the building-side logistics. With 20+ in-house W-2 carpenters, when a sub cancels you don't lose your reserved elevator slot.
Bathroom remodel costs in St. Petersburg run higher than national averages for two reasons: the age of the housing stock and the prevalence of slab-on-grade construction. Moving a drain in a slab home means cutting concrete — a labor cost that doesn't exist in homes with crawl spaces or basements.

“We've had to schedule elevators — one downtown building after COVID had a service elevator shared with dog owners that kept malfunctioning, so carpenters dragged tools 28 flights of stairs up and down — all that time is billed to the owner because it's not our fault.” — Jeremy Bonnewell, Co-Owner
Need accessibility features like grab bars or a curbless shower? Revolution approaches accessibility as good design that makes bathrooms safer for everyone.
If your remodel involves plumbing or electrical changes, yes — the City of St. Petersburg requires permits. Cosmetic work (new tile, paint, vanity swap without moving plumbing) does not. Bathroom projects with plumbing include a shower pan inspection, a bathroom-specific permit step. Current permitting timeline in St. Pete is 3–5 weeks. Revolution handles all permit applications and building department coordination — you don’t need to visit any city offices.
Only if your home is in an AE or VE flood zone and the total renovation cost exceeds 50% of your home’s pre-improvement market value. This is the “substantial improvement” threshold. If triggered, the structure may need to meet current flood elevation requirements, which can affect bathroom plumbing that runs below the base flood elevation. Revolution calculates this threshold before quoting on flood zone properties — it’s too important to discover after permits are pulled.
A cosmetic refresh on a standard 5x7 bathroom runs $20,000–$30,000. A full master bath remodel with layout changes runs $40,000–$70,000. The St. Pete-specific cost factor is cast iron plumbing — replacement adds $10,000–$20,000 in homes built before the 1970s, which includes most of Old Northeast, Kenwood, Crescent Lake, and Euclid-St. Paul’s. A camera scope ($100–$300) before demo catches this early.
Interior bathroom work in St. Pete’s historic districts generally doesn’t require Historic Preservation Board review. However, if your remodel includes an addition that changes the home’s exterior footprint or roofline — like bumping out a wall to expand a bathroom — you’ll need a Certificate of Appropriateness. Revolution has experience navigating the review process in Granada Terrace, Kenwood, and other designated districts.
