I have a leak from upstairs bathroom to the downstairs powder room. I could not locate the source of the leak but it appears to be when someone takes a shower upstairs.

Couple of questions. Is this a job for a plumber or a contractor?

Second is how much would it cost to fix such a problem on average?

Thank you in advance.

Good day LT,

Sounds like there may be a connection with the drain, and or the shower pan itself. Is this a tiled shower floor or a plastic pan? More information is required.

You may have to cut into the powder room ceiling, (and repair it), to determine the cause of the leak. A good handyman contractor should be able to do the repair, but they are all different depending on the extent of repair.It would be great if repair could be done without damaging your shower tile. Maybe a cut in the wall behind tub faucet and shower riser. Get a handyman or two in for estimates to see how far your can of worms will go! Bon chance!

If it was me I would put a 1/4 inch hole in the ceiling then place my camera inside run the shower and get the answer your looking with a proper quote to fix the problem at the end of the day using my License plumber to do the repairs. As for getting a handyman to do the job brings real concerns as there is no way a handyman can carry the amount of liability insurance that a plumber must carry.

Hope this helps. At the end of the day it not that big of a job and the cost should not be unrealistic.

I agree, that a handyman is not the route.

You need a proper contractor that can open things up and then find the true cause of the leak. Then I would have one of my plumbing subs fix that issue. And we would then rebuild the ceiling and your shower if necessary.

Thank you all, you've been very helpful. To answer your question Andrew its a full size tub. I could check the plumbing around the faucets, no problem there. I guess the problem is in drainage but the water seems to be clean (odourless, no soap, clear color).

Thanks again gentlemen.
