We had a new shower installed several months ago. Recently I noticed water slowly leaking from a side wall where the tile meets the floor for a few days after using the shower. It is not leaking from the wall with the shower head or controls but a side wall. If I don't use the shower is seems to stop after several days. Do you recommend sealing all the way around the tile floor or will this create a mold problem if the water is leaking under the tiles from another source?

Thanks for any help.

Hello Wilton,

I think to seal it in is the wrong thing to do, in my opinion you have a water leak coming from some where and you need to find the source.
If you seal everything up, then you could be creating a bigger problem for yourself.
Even though you say it's not coming from the wall the shower head etc.. Is on, it could be and then travelling around the walls looking for the nearrest escape root, which of course is where the tile meets the floor.

You are going to have to check the pipework, I don't know if there is a meter that you can buy to do this rather than take off some of the tile work, but if there isn't you'll have to locate your pipes, to find the leak. It may only be a splintered pipe but over a period the water is building up and obviously seeping through. If you leave it the pipe may go completely causing all kinds of problems.

Does the shower have a guarantee? if so brilliant call the fitters back in, it's my guess that this is down to the installation, even if you can't find the guarantee still call them back, it could be shoddy workmanship or purely loose pipe fittings...

Hope this helps

I agree, you need to find the leak and fix it. This could be a drain issue or a supply line. Since it leaks after use I'd lean toward drain or bad gruting.
