How Much Does a Bathroom Remodel Cost in St. Petersburg, FL?

Most bathroom remodels land between about $6,000 and $25,000. Cost guides updated in 2026 put the national average near $12,000. One guide puts it at $15,586. Per square foot the common band is $70 to $250.

Scope moves that number more than anything else. A paint and vanity refresh sits at the bottom. A full tear out with new waterproofing and tile sits at the top. These are market numbers from published cost guides. They are not our price list.

What does a bathroom remodel cost by scope?

Here is how the 2026 national cost guides break the work down. Every row below assumes the room stays where it is.

The ranges overlap because each guide slices the work a little differently. Read them as a band. A full bathroom remodel in an older St. Petersburg home usually lands in the middle two rows.

What does it cost by bathroom size?

Size drives material counts and labor hours. One 2026 guide prices the job by the size of the room.

A second guide narrows those bands. It puts a 40 to 60 square foot bathroom at $12,695 to $14,845. It puts a 130 square foot primary bath at $22,370 to $24,715. A small bathroom is still not cheap per square foot. The same fixtures, tile cuts and waterproofing go into a small room as a big one.

What actually drives the price?

Tile is the first lever. Cost guides put tile work in a bathroom at roughly $600 to $1,800, with an average near $1,326. Large format tile on walls and a ceiling costs more to cut and set. A small field of standard tile goes faster.

Waterproofing is the part you never see. A tile shower needs an uncoupling and waterproofing membrane under the tile and across the shower floor. Skipping that step is how a shower fails in five years. The guides fold it into the shower line, which runs from about $1,500 to $8,000 based on the build. Tile installation is also where most of the skilled hours go.

The vanity is the third lever. Guides show vanities from a few hundred dollars up past $3,000. Cabinetry averages about $2,900. Layout is the fourth lever. Moving where the fixtures sit pushes the job into a different price class.

Labor is the biggest single share. Two national guides put labor at 40 to 65 percent of the total. That is why two bathrooms that look alike can price far apart.

What is different about St. Petersburg bathrooms?

Much of the middle of the city is 1950s to 1970s concrete block. Those bathrooms are small, often 5 by 7 or 5 by 8. The tile is often set straight to block or to an old mortar bed. Tear out takes longer, and what comes off the wall is heavier than drywall.

The 1920s bungalows in Historic Kenwood, Old Northeast and Roser Park bring different work. Floors move over time, old subfloors need prep, and the rooms are rarely square. Both kinds of home add labor hours before a single new tile goes down.

Then there are the 2024 storm rebuilds. Helene and Milton flooded Shore Acres, Riviera Bay and the beach towns. Many of those homes were opened to the studs. A bathroom inside that kind of rebuild prices like a full gut, because that is what it is.

Do permits change the cost in St. Petersburg?

National cost guides put permit fees at roughly $100 to $1,000 on a bathroom job. Local rules matter more than the fee itself.

The City of St. Petersburg’s own permitting page points to a Florida law, House Bill 803, effective July 1, 2026. Work on a single family home totaling less than $7,500 may be exempt from permitting. The exemption is narrow. It applies only outside a flood hazard area. It also requires that the work include no structural, mechanical, electrical, plumbing or gas parts.

Flood zone homes carry a second rule. The city calls it the 49 percent rule. Repairs and improvements that reach 49 percent of the home’s pre damage market value trigger it. The whole structure then has to meet current flood rules. The city says the count includes work you do yourself and donated materials. Those are the city’s published rules, not advice. Confirm your own address and job with the city before you set a budget. Florida also runs a public license lookup at myfloridalicense.com if you want to check a trade license.

What about a small bathroom or a condo?

A 5 by 7 bathroom remodel runs about $5,000 to $15,000 in 2026 by one guide’s count. Cutting the shower out of the plan is the biggest single saving. Keeping the existing layout is the second.

Condo bathrooms downtown and in the beach towns add their own factors. Building rules on work hours and elevator use can stretch a job. Concrete floors and shared walls change how tile and waterproofing get handled. None of that shows up in a published average, so price a condo bathroom on its own terms.

A tile shower build is usually the largest single line in a bathroom budget. Guides put a tub to shower conversion at $1,200 to $10,000 all in. There is more on that in what a tub to shower conversion costs in Florida.

How long does a bathroom remodel take?

Cost guides report most bathroom remodels running two to twelve weeks. Two to four weeks is the common figure. Tile and waterproofing set the pace, because both need cure time before the next step.

Your own timing depends on the size of the room and on what is behind the walls. We talk through that when we look at the job.
