A significant portion of St. Petersburg's housing stock was built before 1970. These homes typically have cast iron drain pipes that are now 50-80+ years old. Cast iron corrodes from the inside out — you may not see damage until a pipe fails. During a bathroom remodel, we scope the drain lines with a camera to assess condition. Full cast iron drain replacement in a bathroom costs $2,500-$6,000 depending on accessibility and the number of fixtures (per local plumbing trade estimates). We strongly recommend replacing cast iron drains during a gut renovation rather than tiling over aging pipes that may fail within 5-10 years.
Old Northeast is one of St. Petersburg's most desirable neighborhoods, with homes dating to the 1910s-1940s. Many still have original hex tile floors, pedestal sinks, and claw-foot tubs. Some homeowners want to preserve these period details while upgrading plumbing and adding modern shower functionality. Others prefer a complete modernization. Either way, expect to encounter galvanized supply lines, cast iron drains, and outdated electrical — all of which need replacement to meet current Florida Building Code. Full plumbing replacement in an Old Northeast bathroom adds $3,000-$8,000 to the project.
Snell Isle properties sit along the waterfront, and many fall within FEMA flood zone AE. Ground-floor bathrooms in flood-prone areas may require flood-resistant materials below the base flood elevation (BFE) — including moisture-resistant drywall, elevated electrical outlets (minimum 12 inches above BFE), and water-resistant flooring. These requirements add $1,500-$4,000 to a ground-floor bathroom renovation but protect your investment against flood damage.
Kenwood's 1940s-1950s bungalows frequently have original tub-and-shower combos in tight 5x8-foot bathrooms. The most popular conversion in this neighborhood is removing the tub and installing a curbless or low-curb walk-in shower — typically with large-format porcelain tile and a linear drain. Tub-to-shower conversions cost $6,000-$12,000 as a standalone project or less when part of a full renovation (per Clearwater Shower Bath, local market data). Walk-in showers make small bathrooms feel significantly larger and are a strong selling point in St. Pete's active real estate market.

Bathroom remodels in St. Petersburg require permits from the City of St. Petersburg Development Review Services for any plumbing changes, electrical work, or structural modifications. Fixture-for-fixture replacements in the same location may not require a permit, but moving a toilet, relocating a shower, or adding new plumbing lines does.
Typical permit cost: $200-$800. Permit approval timeline: 10-15 business days. We pull all required permits through the City of St. Pete (not Hillsborough County — St. Petersburg has its own permitting jurisdiction in Pinellas County).
Every Mason Homes project begins with an on-site consultation — we look at the space, listen to your goals, and put together a fixed-scope estimate you can compare line-by-line. No pressure, no obligation.

How much does a bathroom remodel cost in St. Petersburg? A half-bath update costs $4,000-$14,000. A standard full bathroom renovation runs $18,000-$45,000. A high-end master bathroom reaches $45,000-$75,000+. The average St. Pete bathroom project comes in at $28,000-$32,000 (per NovaCoreBuilders, 2026). Historic homes with cast iron pipe replacement add $2,500-$6,000 to the total.
Should I replace cast iron drain pipes during my bathroom remodel? If your St. Pete home was built before 1970 and still has original cast iron drains, yes. Cast iron pipes have a 50-80 year lifespan, and many in St. Petersburg are at or past that mark. Replacement costs $2,500-$6,000 per bathroom. Replacing them during a renovation — when walls and floors are already open — costs significantly less than replacing them after the renovation is complete.
How long does a bathroom remodel take in St. Petersburg? A powder room update takes 1-2 weeks. A standard full bath takes 3-5 weeks. A master bathroom renovation takes 5-8 weeks. Add 10-15 business days for City of St. Petersburg permit approval. Custom vanity and tile orders may add 2-4 weeks of lead time before construction begins.
Do I need a permit for a bathroom remodel in St. Pete? Yes, if the project involves plumbing changes, electrical work, or structural modifications. Permits are issued by the City of St. Petersburg Development Review Services — not Hillsborough County. Permit costs range from $200-$800. Cosmetic changes like painting, mirror replacement, and hardware swaps do not require a permit.
What are the flood zone considerations for Snell Isle bathroom remodels? Many Snell Isle properties sit in FEMA flood zone AE. Ground-floor bathrooms below the base flood elevation may require flood-resistant drywall, elevated electrical outlets (minimum 12 inches above BFE), and water-resistant flooring. These requirements add $1,500-$4,000 to a ground-floor bathroom renovation.
What is the most popular bathroom upgrade in St. Petersburg? Walk-in shower installations and tub-to-shower conversions are the most requested upgrades across all St. Pete neighborhoods. The average walk-in shower installation costs approximately $6,100 (per Clearwater Shower Bath). In Old Northeast and Kenwood, converting a tub/shower combo to a curbless walk-in shower in a 5x8-foot bathroom is the single most common project.
