Where the Money Goes, Line by Line
Here is that money broken into the lines that appear on our proposals, for a 5×8 guest bath up through an 8×10 primary.
| Line item | Typical cost | What moves it |
|---|---|---|
| Demolition and debris removal | $800 to $1,500 | Top of range if terrazzo comes out |
| Plumbing, fixtures staying put | $1,500 to $2,500 | Same locations, new valves and trim |
| Plumbing, moderate changes | $2,500 to $4,500 | Moving a vanity or shower valve |
| Plumbing, layout change or replumb | $4,500 to $8,000+ | Slab cut, new drain, failed cast iron |
| Whole house repipe | $6,000 to $12,000+ | Galvanized supply at end of life |
| Electrical and lighting | $1,500 to $3,500 | GFCI, dedicated circuit, fan, fixtures |
| Waterproofing membrane and backer | $300 to $800 | Never the place to save money here |
| Tile material | $2 to $25 per sq ft | Porcelain $4 to $15, stone $10 to $25 |
| Tile labor | $8 to $12 per sq ft | $15 to $25 inside a waterproofed shower |
| Custom tile shower, complete | $4,000 to $12,000 | Basic up to bench, niches, multiple heads |
| Tub to shower conversion | $3,500 to $7,000 | Demo, plumbing, pan, tile, glass |
| Freestanding tub installed | $3,000 to $6,000 | Alcove tub is $800 to $1,500 |
| Vanity | $300 to $8,000 | Stock, semi custom, or custom build |
| Vanity top installed | $60 to $130 per sq ft | Granite $60 to $120, quartz $70 to $130 |
| Frameless glass enclosure | $1,200 to $2,500+ | Semi frameless at $800 to $1,200 performs the same |
| Exhaust fan installed | $300 to $600 | Humidity sensing is worth the upcharge |
| Permits and inspections | $300 to $800 | Varies by scope and jurisdiction |
| Contingency | 10 to 20 percent | Not optional on a pre 1970 house |
Labor is 40 to 50 percent of every bathroom, which is why downgrading materials saves less than people expect. On a $30,000 bath, $12,000 to $15,000 is labor no matter what tile you pick. Second number worth writing down: on a pre 1970 house, budget 20 to 30 percent more than the same bathroom in newer construction. That is not padding, it is what the walls hide.
What Is Actually Behind the Wall in a St. Petersburg Bathroom
If your house went up between 1950 and 1968, and most of the concrete block ranches from Pinellas Point through Meadowlawn and Disston Heights did, your bathroom drains are cast iron in the slab. Cast iron in Florida soil lasts roughly 50 to 75 years, and the ones here are past it. The failure looks the same every time: the bottom of the pipe scales and rots out while the crown still looks fine from the cleanout, so the line reads as open right up until it does not. A camera scope before demo costs almost nothing next to finding out with the tile already gone. If a run under the bathroom has to go, we saw cut the slab, cut in PVC, and repour, which is the $4,500 to $8,000 replumb line above. If the branch keeps failing out under the hallway, you are into $6,000 to $12,000 and up.
Galvanized supply is the other half of that era. It corrodes from the inside out, so the first symptom is pressure, not a leak: the shower drops to a trickle when somebody runs the kitchen sink. Replacing only the bathroom branch moves the restriction, it does not fix it. Owners of a 1950s or 1960s block house are usually better off pricing a full repipe in CPVC or PEX while the bathroom walls are already open, because the access holes and drywall patching are most of the cost and you only want to pay for them once.
Under the tile in a lot of these houses is terrazzo, poured in place when the house was built, usually gray or pink with brass or zinc divider strips. Two things matter. If somebody thinset ceramic straight over it in 1994, that tile comes off with the terrazzo surface attached, and grinding it back to a polishable finish is restoration work, not demo work. And terrazzo is bonded to the slab and heavy, so full removal is a jackhammer and dumpster weight job that pushes demolition to the top of that $800 to $1,500 line or past it. Sometimes the right answer is to keep it. In an Old Northeast or Historic Kenwood house, original terrazzo is worth more than whatever tile would replace it.
The 1920s Craftsman bungalows in Kenwood and Old Northeast are a different animal. No slab. Wood floor framing over a crawl space, a cast iron closet bend at the toilet, and a subfloor that has usually been getting damp for years before anyone noticed. Plan on framing repair once it is open. Structural repairs found at demo run $500 to $5,000 or more. Wiring is often two conductor with no ground, and code will require GFCI protection and usually a new dedicated circuit before an inspector signs off. Plaster over wood lath does not patch like drywall either, so we plan wall openings instead of improvising them.
Flood Rules and Which Permit Office You Actually Report To
Shore Acres, Riviera Bay, Coquina Key, Bahama Shores, and the low blocks around Snell Isle sit in FEMA mapped special flood hazard areas, and the City of St. Petersburg reviews permits against the 50 percent substantial improvement rule. In plain terms: if your improvement value reaches half the market value of the structure, not counting the land, the whole house has to be brought into flood compliance, which on those parcels generally means raising it. One bathroom rarely gets there alone. It still matters, because the value on your permit application is the number reviewed, and many of these houses already carry permits on file from earlier storm repairs. That question is much cheaper to ask before you file than after. We handle it with the city and scope the work knowing the answer.
Jurisdiction trips people up too. A St. Petersburg mailing address does not always mean a City of St. Petersburg permit. Lealman and other unincorporated slivers north and west of the city limits carry St. Pete zip codes but are county jurisdiction, so those permits run through Pinellas County Building Services in Clearwater rather than the city counter downtown. Fees and review times differ. We confirm jurisdiction by parcel before we hand you a price.
A Word About One Day Bathroom Remodels
Search for bathroom remodeling in St. Petersburg and most of what you will see are one day remodel franchises. What they install in one day is an acrylic liner glued over your existing tub or shower. It hides problems, it does not fix them. Trapped moisture, hidden rot, and mold stay right where they were. We wrote honestly about this in one day vs 10 day vs full bathroom remodel and our 10 day bathroom guarantee. A real renovation takes a little longer and is built to last decades, not to cover up the last problem.
Built for St. Petersburg Homes
Pinellas homes have their own challenges. Shore Acres and Snell Isle houses deal with flood zone rules and salt air that eats cheap fixtures. The 1920s bungalows in Historic Kenwood and Old Northeast hide cast iron drains and undersized wiring behind beautiful plaster walls. Mid century block homes in Pinellas Point and Lakewood Estates often have original 1960s bathrooms with galvanized supply lines at the end of their life. We remodel in these neighborhoods every month, we know what is behind the walls, and we manage City of St. Petersburg and Pinellas County permits on every job. The 1920s and 1930s houses on Snell Isle add the city’s historic review on top of that, which is why they get their own Snell Isle historic remodeling page.
Waterfront condos are their own category. Buildings along Beach Drive, Bayshore, and the Snell Isle towers almost always require association approval before a permit is even applied for, plus a certificate of insurance naming the association, licensed trades on file, restricted work hours, and a reserved service elevator for demo and material runs. Many also set a sound rating under any hard flooring. That adds a week or two on the front end, and cast iron risers shared between stacked units mean plumbing changes are rarely as simple as they look.
Bathroom Remodel Timeline in St. Petersburg
| Phase | Duration | What is happening |
|---|---|---|
| Design and selections | 1 to 2 weeks | Measure, layout, tile and fixture picks, quote signed |
| Permit application and review | 2 to 4 weeks | City or county plan review. Ordering runs alongside |
| Demo and haul out | 1 to 2 days | To studs and slab. Add a day for terrazzo |
| Rough plumbing and electrical | 2 to 4 days | Drain repairs, supply, new circuit, fan duct |
| Rough inspection | 1 to 3 days | Nothing closes up until it passes |
| Backer, waterproofing, flood test | 2 to 3 days | Membrane on, pan filled and held overnight |
| Tile floor and walls | 3 to 6 days | Large format is fast, mosaic is not |
| Vanity, top, fixtures, trim | 2 to 4 days | Top templated after the vanity is set |
| Shower glass | 7 to 10 days after tile | Measured after tile is set. The usual holdup |
| Paint, final inspection, walkthrough | 2 to 3 days | Punch list closed before final payment |
Total on site time is 2 to 4 weeks, with 3 to 6 weeks of design and permitting ahead of it. A primary suite with layout changes and a slab cut runs 5 to 6 weeks on site. If it is the only bathroom in the house, say so at the consultation and we sequence the work to shorten the days you are without it.

Bathroom Remodeling in St. Petersburg: Common Questions
How much does a bathroom remodel cost in St. Petersburg?
Most full bathroom remodels run $30,000 to $50,000. Smaller guest baths start around $18,000. Spa style master bathrooms reach $75,000 or more. Tile selection and layout changes are the biggest cost drivers. Those are the same bands we publish on our Tampa Bay bathroom remodel contractor page, which also walks through how to check a bathroom contractor’s license before you sign.
How long does a bathroom remodel take?
Plan on 2 to 4 weeks of construction for a full remodel. Design and permitting before that usually take 2 to 4 weeks depending on city review times.
Do I need a permit to remodel a bathroom in St. Petersburg?
Yes. Any work that touches plumbing, electrical, or walls requires a permit from the City of St. Petersburg or Pinellas County. We pull and manage every permit. It is included in the project.
What happens if you find failed cast iron drain under my slab?
We camera the line before demo on any house from that era, so it is usually a known cost rather than a surprise. If a section under the bathroom is gone, we saw cut the slab, replace it with PVC, and repour, which is the $4,500 to $8,000 replumb line. If the failure runs past the bathroom, figure $6,000 to $12,000 and up. Anyone quoting a 1950s Pinellas bathroom without looking at the drain is guessing.
Does the FEMA 50 percent rule apply to a bathroom remodel in Shore Acres?
It applies to the parcel, so yes, the city reviews it. A single bathroom is rarely valued at half the structure’s market value, so most projects clear it easily. The risk sits with smaller older houses on expensive lots and houses that already carry recent permits. We check the flood zone and permit history for your address before writing the scope, and if you are near the threshold we say so rather than letting you find out at review.
There is terrazzo under my bathroom tile. Should I keep it?
Often, yes. If the terrazzo is intact and the divider strips are sound, restoring and polishing it usually costs less than removal plus new tile, and it is original to the house. If it was thinset over, the surface comes up damaged and restoration takes a specialist. Removal is a jackhammer job that adds demo hours and dumpster weight. We look on day one and give you both numbers.
Is a one day bathroom remodel worth it?
If you need a quick cosmetic fix to sell a house, maybe. If you plan to live with the bathroom, no. Acrylic overlays trap moisture and hide damage. A permitted renovation costs more and lasts decades.
Can you make a small bathroom feel bigger?
Yes, and it rarely requires moving walls. Curbless showers with glass panels, wall hung vanities, better lighting, and large format tile change how a small Pinellas bathroom feels.
