A standard cartridge swap on a Safety Harbor 1960s, 1970s, or modern shower valve runs $189 to $385 depending on parts and access. The right call when the underlying valve body is sound, supply lines are not galvanized or polybutylene, and the brackish exposure has not yet degraded the cartridge body.
A salt-air refresh on a Bayshore Drive or Philippe Park property (PVD or stainless trim swap, showerhead replacement with mineral-resistant fixture, cartridge service combined) runs $385 to $785. Right answer when the underlying valve is sound but visible chrome has pitted from brackish exposure.
A full Moen, Delta, or Kohler valve body replacement with FBC P2722 anti-scald compliance and silicon bronze fittings on coastal properties runs $685 to $1,085 installed (slightly higher than standard inland pricing due to the silicon bronze upgrade).
A combined galvanized-to-PEX-A repipe plus shower valve upgrade on a 1950s downtown bungalow runs $2,985 to $5,485 for the affected bathroom. Larger full-house repipes on 1950s bungalows run $8,500 to $16,500 depending on access complexity and slab conditions.
Premium Brizo, Kohler ProMaster, Newport Brass, or Hansgrohe AXOR thermostatic cartridge service runs $485 to $885. Multi-head luxury rough-in for new construction or gut renovation runs $2,800 to $5,800 plumbing portion.
Full pan replacement on 1995 to 2005 luxury vinyl liner showers runs $1,800 to $3,200 plumbing only plus tile sub coordination at $1,500 to $4,500. We pull the Pinellas County mechanical permit on any valve relocation, repipe, multi-head rough-in, or pan replacement.
