Question DetailsAsked on 8/9/2013

How much should it cost to replace a bathroom tub valve?

I have a one knob shower faucet in my bathtub. It was leaking inside the wall right at the valve. I was told that to replace the valve and shower nozzle and all involved would cost $425.00 Is that reasonable?

Do you have the same question? Follow this Question

It depends on how difficult it is to get to the valve... the value costs about $75 to $100, the rest is labor. If the value is readily accessible through the back of the wall, then this is too high.. but if the plumber has to remove and replace the tile or otherwise open the tub side itself, then is not unreasonable.

If the valve is accessible from the other side of the wall, consider opening the drywall yourself and when the plumber is done replace the drywall and repaint yourself.. This should save you some money, if you are comfortable with doing this.

also, this is not a difficult repair to do yourself if you are reasonably handy...

turn the water off,

open the wall from the back side,

remove the value...

Buy a value with the same plumbing configuration..

(Take the old valve to the store and check the configuration of the new value against the old.)

Re-Install the valve

Repair the hole in the wall.

The prior comment suggested doing it yourself - that really applies only if it is connected to all pipes with threaded connections - many valves are soldered in, and shower valves are one of the toughest soldering jobs because of the large mass of metal in the valve, to do it without distorting the valve or damaging it.

if threaded, be sure to get teflon plumbers tape to seal the threads, and check out a Youtube video on how to apply plumbers tape to the male threads to prevent leakage.

On your $ question - $425 seems steep, IF accessible from the back of the wall. If have to go through the valve hole in the surround or tile, then maybe in the ballpark, though still high unless you are in a big city like NY or Chicago or Boston - is quite a tricky maneuvering exercise from the front - commonly involves pulling it out by cutting the pipe from the floor below, soldering the new one, and putting the pipe back up from below into place, then soldering the top connection.

i just replaced a shower valve for a customer. I had to tear out sheetrock from behind the shower valve. They had a cheepo depot valve with thread fittings and conveniently ran copper with water hammer arrestors and teed off with GALVANIZED which was clogged to the size of a coffee straw. I cut out all threaded fittings and soldered wirsbo pex connectors directly to the copper. The homeowner picked out a Delta faucet with adjustable pressure and temperature. The valve and trim package was $240 and comes with a lifetime warranty. Labor was $150. Homeowner was responsible for patchwork and gave them option to call a few people I use. Total bill was $390.

Because of the difficulty involved, $425 is a fair minimum for parts and labor (depending on model). The person who said " this is not a difficult repair to do yourself" obviously underestimates his skills and assumes every one possesses similar tallent. Most older homes have souldered plumbing, so unless you have sufficient souldering skills I recomend leaving it to the pro's (including high quality Handy men)

No body mentions anchoring the fixture body and pipes which can be difficult and time consuming. Every replacment is different and (in my opinion) requires an on site evaluation with consideration given to make and model before offering a price.

My services are turn key, no need to call for Dry wall repair, Painters or Tile repair person, I do it all with quality.

I love my job

Again a lot depends on what kind of plumbing you have and what kind of new valve is going in and how hard it is to get to keep in mind unless you just want a newer model 9 times out of ten you can fix the valve by repacking it for much less then the cost of replacing it most contractors want you to replace it because they know they will make more for that

Hi my name is Matt and I am a plumber people get us confused with handy men a lot the prices are a lot difrenet, but keep in mind are prices are the way they are for the following reasons. A bad plumbing job by a handyman in the end will cost u much more then if u spent the money and hired a real plumber who does it right. See plumbing is all I do and I have many years experience. Water is not something to mess with if u don't know what u are doing bc in the end if it's messed up u will have leaking pipes in ur walls. This could cause lots of money in water damage, and you could ever have health problems(mold). I would never go to the doctor to have my cavity filled so why people try to get someone to do plumbing who is not licensed and been doing this is beyond me. Save ur self the money, stress, and risk call a real plumber. To answer the ? That's just about right $425 if it's cut and dry if it's a difficult job and not easily accesable then more like $725. O ya and plumbers don't fix drywall and tile and if they do then it's to good to be true. A jack of all trades is a master of none!?!?!👍🏻

I just had bathroom tub valve replacement from Simply Green Plumbing from Los Gatos, total was about $885, I asked for the break-down charges, but they didn't give me, it was very pricy and overpriced!

The person that that said to change a value (valve) was a simple job and the lady should be ok, well if sheʼs not a plumber by the time she buys parts and tools and mop up all the water, replace the carpet, and repair all the damage, four hundred dollars wonʼt sound so bad.

Yes, I would say this is reasonable. If "all involved" means cutting open the drywall, removing old valve and installing a new one, and then repairing the drywall (assuming they know what they are doing and the plumbing and drywall work are good) then it's a great deal. I just did one for a customer for $750. That included the piping to the shower head and the tub spout And new trim kit with the valve And you'd never know anyone cut a hole in the drywall by the end of it.

I truly don't understand people saying that this is "an easy diy job". It really is not. Especially considering a lot of houses have copper plumbing, and then adding support blocking for everything from the backside can be difficult like one of the other commenters mentioned.

Answered 7 months ago by HTXhandyman


I myself do a lot of valve replacement I am always by the hour this job can run low as 250 as high as 1200 for labor depending what you are getting into I have found many surprises opening walls up the last valve I installed the copper lines we're full of small stones Go figure so again it's all relevant
