Most plumbers can fix a wide range of problems that come up with bathtubs and showers, including slow or clogged drains, leaky fixtures, insufficient water pressure and more. Repairs for these issues vary in price, depending on the cost of parts, the extent of labor required and any necessary taxes. The national average cost for shower repairs is $80–$240.
Another type of specialist can help with chipped, cracked or stained surfaces in your porcelain or fiberglass shower or tub. Some professionals specialize in resurfacing, repairing or relining showers and tubs. Sometimes these pros are plumbing contractors, and sometimes resurfacing is their main focus.
Slow or clogged drain
Tubs or showers that drain slowly or not at all can generally be fixed by having a plumber cable (or "snake") the drain. James Jones of Loyalty Drains and Sewers charges $150 for this service.
Jones of Loyalty Drains and Sewers says that sometimes people think they have low water pressure when in fact the issue might be that the volume of water moving through the pipes to the showerhead or tub faucet is constricted. Jones typically charges $400 to clear out water lines obstructed by debris, calcification or pipe erosion to increase water volume. If water pressure is too high, customers may be using more water than they need, which results in a higher water bill. In some locations, using excess water may not be allowed by law. To install a pressure reducing valve (PRV), Jones charges $485 for 3/4-inch pipe, which is most common, or $700 for 1.5-inch pipe.
Issues with temperature control often can be traced back to the water heater, which may just need to be turned up or down. Homeowners can easily do this themselves. If it turns out that the water heater has a problem, most plumbers can repair or replace it. The cost for water heater repair or replacement varies widely, from around $200 to thousands of dollars, depending on what type of water heater you currently have (tank or tankless, powered by gas or electricity) as well as what type you replace it with.
Shower or tub surface
Sometimes getting a like-new surface in your bathtub or shower is a matter of having it resurfaced. Fuentes Services in Cronoa, California, typically charges $250 for fiberglass and $350 for porcelain tub resurfacing.
A variety of issues can crop up in your shower, tub or bathroom sink, and repair costs will vary greatly. On average, a leaky or dripping faucet costs $150–$500 to fix, depending on the cause, and a broken diverter costs $125.
