How much does a bathroom remodel cost in St. Petersburg?

In St. Petersburg, a cosmetic refresh on a standard 5x7 bathroom runs $20,000 to $30,000. A mid-range master bath remodel with layout changes, new tile, a custom shower build, and upgraded fixtures lands between $40,000 and $70,000. Luxury builds with heated floors, frameless glass, and premium stone start around $100,000. Building a brand-new bathroom where none existed runs $75,000 to $90,000 because every system has to be pulled from scratch. Per-square-foot, bathrooms are the most expensive room in the house — every square foot is tile, plumbing, fixtures, lighting, and ventilation.

How long does a bathroom remodel take in St. Pete?

A 5x7 cosmetic refresh takes 4 to 6 weeks of construction once materials are on site. A full remodel with layout changes runs 8 to 14 weeks. Major renovations with drain relocation, framing changes, or flood zone review can stretch to 16 to 20+ weeks. Add 3 to 5 weeks of permitting before construction begins for any project that touches plumbing or electrical. Tile selection lead time and any cast iron drain replacement are the two most common schedule extenders on Pinellas County bathroom projects.

What's the order of work for a bathroom remodel?

Sequence of work for a bathroom remodel is demolition, framing, plumbing rough-ins, electrical rough-ins, mid-construction inspection, drywall and waterproofing (Schluter Kerdi membrane on most modern shower builds), tile, glass for shower doors, vanities, paint, and finally fixtures and trim. Tile selections should be locked in before construction starts so material is on site when the tile setter arrives — tile suppliers are notoriously optimistic about lead times.

Should I replace cast iron drains during a bathroom remodel?

Usually, yes — on any remodel of any size in pre-1970s St. Pete homes (Old Northeast, Historic Kenwood, Snell Isle, Shore Acres, Crescent Lake), the cast iron drain typically gets replaced because the best time is now while the walls are open. There is nothing wrong with cast iron in great shape — it's strong when new — but 50 years of Drano and high-pH solvents cause rust and cracking. A plumbing camera scope ($150 to $350) lets you make the call before committing to a budget. We almost always get a camera down the pipes to know what we're dealing with and tell the story to the homeowner.

Bathroom Remodel Checklist: 12 Steps Before Demo Day

Q: Do I need a permit for a bathroom remodel in Pinellas County?

Yes, for any work that touches plumbing, electrical, or framing. Cosmetic work — tile replacement, vanity swap in the same footprint, fixture trim-outs, paint, flooring over existing subfloor — usually does not need a permit under the Florida Building Code. But tub-to-shower conversions, moving any drain, adding GFCI outlets, or upgrading the exhaust fan with new wiring all trigger a permit. Pinellas County permit fees run $500 to $1,500 and the timeline is 3 to 5 weeks for a full remodel. The shower-pan inspection — a flood test where the pan is plugged and filled with water to check for leaks — happens before tile goes down on any permitted bathroom build.

Q: Can I renovate a bathroom for $10,000?

Not in St. Petersburg, in most cases. The $10,000 figure circulating on national content farms reflects materials-only on a tiny refresh in a low-cost market. In Pinellas County, even the most cost-conscious 5x7 refresh — new tile, basic vanity, mid-range fixtures, paint — typically runs $20,000 to $25,000 once labor is included. The realistic floor for a permitted refresh by a licensed contractor with W-2 carpenters and weekly budget transparency is around $20,000.

Most St. Petersburg bathroom remodel surprises start before the first tile is removed — missed cast iron drain inspections, undersized exhaust fans, layout decisions made after rough-in, and tile selections that arrive three weeks late. This 10-step checklist covers the planning decisions Revolution’s superintendents walk every Pinellas County client through before demolition starts: budget by scope tier ($20,000–$30,000 for a 5x7 refresh, $40,000–$70,000 for a master bath remodel), Schluter Kerdi waterproofing, cast iron drain decisions in pre-1970s Old Northeast and Historic Kenwood homes, Florida Building Code permits and the shower-pan inspection, and the order of work that prevents mid-project rework.

Why a Bathroom Remodel Plan Matters in St. Pete

Bathrooms are the highest cost-per-square-foot room in a St. Petersburg house. Every square foot is tile, plumbing, fixtures, lighting, ventilation, and waterproofing — there is no “just drywall and paint” portion of a bathroom. That density of systems is also why bathroom remodels go off the rails the fastest when they’re scoped sloppily. Most of the surprises we open up — failed cast iron drains in pre-1970s Old Northeast and Snell Isle homes, original 1950s shower pans rotting under tile, undersized exhaust fans growing mildew in St. Pete summer humidity, layout changes that require saw-cutting the slab to relocate a single drain — were preventable with a 30-minute conversation during planning.

The 10 steps below are the planning conversation Revolution’s superintendents walk every client through before demolition. They cover the decisions that drive cost (layout, tile selection, plumbing scope), the decisions that drive timeline (permit lead time, tile delivery, cast iron drain replacement), and the decisions that prevent rework (waterproofing system choice, exhaust fan sizing, accessibility planning at the framing stage). For working with a tight 5x7 footprint, see our 5x8 bathroom remodel ideas. For comparing scope tiers and resale value, see our bathroom remodel ROI guide.

The cost stakes are real. A 5x7 cosmetic refresh in St. Petersburg runs $20,000–$30,000 when scoped well. The same bathroom, scoped poorly — with mid-project layout changes, tile that arrives late, a cast iron drain that fails inspection after rough-in, or a shower-pan failure 18 months after closeout — can land at $50,000+ once rework is added. Planning is the cheapest 30 minutes you’ll spend on the entire project.

Bathroom Remodel Checklist: Plan, Budget, and Design

A bathroom remodel can be an exciting yet tedious project. You need to set a clear plan, budget, and design to achieve your functional and aesthetic oasis. This checklist will help you do just that. It will help you with the overall remodeling process. From choosing a bathroom design style to setting a realistic timeline, this checklist will help you achieve your remodeling goals.

1. Decide on Your Overall Design and Function

Start with how the bathroom will actually be used — not the Pinterest board. In St. Petersburg, the most common bathroom we walk is a 5x7 footprint (5 feet wide, 7 feet deep) in a 1950s–1970s ranch in Crescent Lake, Snell Isle, Shore Acres, or Old Northeast. At that dimension, layout changes rarely earn their keep — the room is at the minimum size for a toilet, vanity, and standard shower. The high-leverage decisions are walk-in shower vs. tub, single vs. double vanity (single is the right call in 5x7), accessibility planning (curbless shower, grab bar in-wall blocking, ADA-benchmark 32″ clear door), and whether to combine the bathroom with adjacent closet space (a layout change that triggers framing work and a Florida Building Code permit).

Style follows function. Pick a tile palette and vanity finish after the layout decisions are locked. The most common scope-creep we see in St. Pete bathroom planning is style-first decision-making — clients lock in a freestanding tub spec before deciding whether they actually take baths, then can’t fit a proper walk-in shower in the remaining footprint.

2. Determine Your Budget and Scope

Set the budget by scope tier, not by square footage. In St. Petersburg, the realistic Revolution Contractors price bands are:

5x7 cosmetic refresh: $20,000–$30,000 (new tile, basic vanity, fixtures, paint — layout and plumbing locations stay)
Mid-range master bath remodel: $40,000–$70,000 (layout changes, custom shower build, upgraded fixtures, possible tub-to-shower conversion)
Luxury master suite: $100,000+ (heated tile floors, frameless glass, premium stone, freestanding tub, double vanity)
Brand-new bathroom (creating one where none existed): $75,000–$90,000 (every plumbing line has to be pulled fresh)

Per-square-foot, bathrooms are the most expensive room in the house — every square foot is tile, plumbing, fixtures, lighting, and ventilation. There is no “just drywall” portion of a bathroom. For the full pricing breakdown by component (tile, vanity, fixtures, plumbing, electrical, permits), see our bathroom remodel cost guide for St. Petersburg. Wondering if the investment pays back at resale? See our bathroom remodel ROI in Florida piece.

Set aside 10–15% contingency for unexpected conditions. The most common surprises in St. Pete are: corroded cast iron drains in pre-1970s homes (replacing the drain stack adds $3,000–$8,000), failed shower pans behind original tile (rebuild adds $4,000–$10,000), galvanized supply lines that need replacement during rough-in, and lead paint or asbestos containment in pre-1978 homes. A plumbing camera scope ($150–$350) before construction lets you make the cast iron decision with full information rather than discovering a corroded drain after demolition.

Revolution prices bathroom remodels with open-book Time & Materials (T&M) pricing — a transparent 30% markup, weekly budget reports, supplier invoices visible to the client, and labor hours by named carpenter. By the time construction starts, 90–95% of the budget is known. You pay for what the work actually costs, not a padded fixed bid that has to absorb the contractor’s risk margin for unknown conditions.

3. Plan Each Element

A bathroom packs every system a house can have into one small room: framing, plumbing supply, drain plumbing, electrical, GFCI outlets, ventilation, waterproofing, tile, finishes, and trim. Plan each one before demolition starts. Revolution’s owner Jeremy frames the “why now” trigger this way: “The second biggest issue is when the waterproofing has been compromised — either in a vanity where the wood has started to get water inside and it’s blowing apart, or in tile where water gets under the tile and the adhesives break down and tiles start failing. That could happen from a leak inside the wall or from failed waterproofing on the front side of the wall. Either way, it accelerates the death of the bathroom and calls for a remodel.”

Walk each element below before locking the budget. Decisions made at the planning table cost zero; the same decisions made after rough-in cost thousands.

Layout

Are you planning to change your existing bathroom layout? Or just touch up here and there for minor improvements? Consider these factors and go with whichever suits your bathroom ideas best.

Flooring

There are numerous materials you can choose from. Tiles, laminate, vinyl, stone, and concrete are all durable and good options. You can also have heated floors to upgrade your bathroom further.

Walls and Ceilings

Consider what changes you want to make to your bathroom walls and ceiling. Do you want new paint, wallpaper, or tiles? Do you want insulated walls for better comfort? Are you looking to change your ceiling surface or height? All these questions are crucial to be answered when planning for the ideal bathroom.

Vanity

Your renovation project can include vanity changes. You might want to replace the countertop, add or remove sinks, or even change accessories like towel bars and faucets. Match these options with your preferences to create the bathroom of your dreams.

Toilet

This is one of the core considerations of a bathroom remodeling project. You might want to upgrade the toilet or add a bidet. You might also want to install new bathroom fixtures like grab bars. These are all important things to consider in a bathroom project.

Bath and Shower

These components offer lots of variations. You can choose a tub and shower combination for your redesigned bathroom. You can also add different types of showerheads that can be mounted on walls or the ceiling. Features also include new and heated towel bars, shower curtain rods, and drains.

Electrical

A bathroom remodel also includes electrical work. You can install new lighting features or outlets for hair dryers. If you want to improve the electrical setup, check if you need new wires or if the existing ones will do. These are important factors in a bathroom remodel checklist.

Plumbing

Plumbing drives the calendar more than any other system. If your home was built before 1975 in Old Northeast, Historic Kenwood, Snell Isle, Shore Acres, or Crescent Lake, get a plumbing camera scope ($150–$350) BEFORE construction starts — cast iron drains corrode from the inside out, and discovering a failed drain stack after demolition can add $3,000–$8,000 and 1–2 weeks to the schedule. On a concrete slab (most St. Petersburg construction), relocating any drain requires saw-cutting the slab to recess a new drain line and pouring fresh concrete — budget $2,500–$6,000 for that single decision. For deeper context on cast iron decisions, see our cast iron plumbing in older homes guide.

Storage

You can upgrade your bathroom with added storage. You can install cabinets or shelves to give you more storage space. You can also add recessed shelving for aesthetic storage areas for your toiletries.

Ventilation

Florida Building Code requires either an operable window or a mechanical exhaust fan. The code minimum is 50 CFM, but in St. Pete summer humidity (regularly 80%+ relative humidity for 5 months a year) we recommend at least 110 CFM ducted to the exterior — never to the attic. An undersized exhaust fan is the #1 driver of mildew and waterproofing failure on otherwise well-built bathrooms. If your bathroom has no operable window (most interior baths and many condos), the fan is required code; consider upgrading to a humidity-sensing model that runs automatically until ambient moisture drops below threshold.

4. Select Your Materials and Finishes

Once you have planned out each element, you can move on to choosing your preferred materials and finishes. You can select what type of flooring, walls, and ceiling you want for your new bathroom.

5. Plan Your Ventilation and Lighting

As we discussed already, ventilation and lighting are core parts of a bathroom. You need to ensure good airflow and lighting conditions to make the most of your redesign. Exhaust fans and windows can help with airflow, while lighting fixtures can help create cozy vibes. Different fixtures can help you maximize these settings and create a functional bathroom that meets your needs.

6. Select Your Paint

A new coat of paint can add to your bathroom aesthetics. Choose a color palette that reflects your style and bathroom design ideas. It will help create the perfect atmosphere for your redesigned bathroom. For example, you can select different finishes and color combinations to complement specific themes you like. This can ensure a successful bathroom makeover.

7. Set Up a Project Timeline

A 5x7 cosmetic refresh in St. Pete takes 4–6 weeks of construction once materials are on site. A full remodel with layout changes runs 8–14 weeks. Major renovations with drain relocation, framing changes, or flood-zone review can stretch to 16–20+ weeks. Add 3–5 weeks of permitting before construction begins for any project that touches plumbing or electrical. Tile selection lead time is the most common schedule extender — tile suppliers are notoriously optimistic about delivery dates.

The order of work matters as much as the timeline. Revolution’s owner Jeremy lays out the canonical bathroom sequence: “Sequence of work for a bathroom is demo, framing, rough-ins of plumbing, then tile, then glass for shower doors, then vanities, paint, and fixtures. We try to secure tile selections before we start construction — it only makes sense in a single-bathroom remodel — it’s going to be a short project, so we need to have that tile on site, especially if it’s a tile that needs to be shipped from anywhere. Tile suppliers are pretty notorious for getting their estimates wrong on how long it’s gonna take to get us something, so we want tile selections done during permitting.”

For the full timeline breakdown including permit lead time, inspection windows, and scope-tier comparisons, see our bathroom remodel timeline guide for Florida.

8. Decide What You'll Do Yourself and What You'll Hire Out

Some tasks are suitable for DIYs, but it is better to leave others to the professionals. For example, you can install new mirrors or other accessories by yourself. However, major renovations such as installing sinks and bathtubs, plumbing, or electrical are best left to the experts. These tasks are complex and need perfection. You can hire a professional remodeling contractor to help with these projects.

9. Talk to the Right Professional

For the complex tasks we mentioned above, get in touch with experienced professionals. They are experts at handling big projects like complete bathroom renovations. Contractors can help realize your vision and create your dream bathroom for you. They are also often licensed and insured, which protects your project and ensures that the work is of high quality.

10. Apply for Permits and Schedule Inspections

In Pinellas County, any bathroom remodel that touches plumbing, electrical, or framing requires a Florida Building Code permit. Cosmetic-only work (tile replacement, vanity swap in the same footprint, fixture trim-outs, paint, flooring over existing subfloor) typically does not require a permit. But tub-to-shower conversions, moving any drain, adding GFCI outlets, or upgrading the exhaust fan with new wiring all trigger permits. Permit fees in Pinellas County run $500–$1,500 and the timeline is 3–5 weeks for a full bathroom remodel.

The inspection sequence on a permitted bathroom is: rough-in inspection (plumbing supply, drain, vent stack, electrical rough), shower-pan inspection (a flood test where the pan is plugged and filled with water for 24 hours to confirm no leaks), insulation inspection where applicable, drywall inspection, and final inspection at completion. Skipping the shower-pan flood test — or worse, tiling over a pan that hasn’t been tested — is the single most common cause of waterproofing failure 12–36 months after closeout.

Revolution handles the full permit application and inspection-coordination process for every bathroom remodel. The 20+ W-2 carpenters in-house manage rough-in scheduling so the inspector arrives on a day the work is actually ready — not three days after the trade was finished and other work has covered up the inspection point.

FAQ

How Much Does a Bathroom Remodel Cost on Average?

A bathroom remodel can cost anywhere between $6,637 and $17,616. A project can have many components, such as new flooring, vanities, and even window and door replacements. Each upgrade costs differently. As a result, the cost of a bathroom remodel can vary.

Can I Renovate a Bathroom for $10000?

Yes! You can renovate your bathroom for $10,000. Most homeowners spend around $12,000 on bathroom renovations. With a budget of $10,000, you can likely refresh the flooring, vanities, or countertops. However, keep in mind that this includes only the material costs. If you hire contractors, labor costs will also be added to the total.
