I have a small leak from an upstairs shower to the room below. I had
removed some sheetrock on the ceiling in the room below for some other
work only to find this small leak. By small I mean aprox. 1 oz of
water per average shower.
I have inspected all the tiles and grout lines. They all look good as
far as I can tell.
It seems that when my wife uses the shower little or no water leaks
vs. when I use it. This tells me that the water is splashing
somewhere for me and not for her.
Any ideas where I can look further? Thanks for your help.
You might want to check the putty job around the drain.
We had a leak that would only happed every so often. I could not see the leak
when we ran the water, but the leak would happen very sporatically.
Well, it turns out that the leak only happened if the tub was filled even a
little. The leak path in the putty was small and no leak happened when the
shower water was free to go down the drain. Plugging the drain would make the
leak in the putty the path of least resistance. I bought a tool to remove and
tighten the drain, took it out, replaced the putty, tightened it back up and
the problem was solved for about $8.
If you have a fiberglass tub or shower, maybe your petite wife (in case she is
reading this!!) does not push down on the plastic floor as much as you do, so
you cause more of a leak than she does???
Just a thought.

Thanks for the advice I will check this. A little bit of more
information though. This is a shower stall and not a tub (not that it
makes a huge difference but maybe there's something different.)
The drain is in the center of the shower and the grate does come off.
I am going to try what you advised - plugging the drain, etc. I'll
let you know.
I had the same problem in my house. Turns out, there was a wide gap between
the tub and the surround, and the caulking wasn't quite holding up to the
job. Water was coming down into my kitchen pantry. I got some of that
adhesive backed rubber stuff as a temporary measure, which is holding so
far, but I'm going to have to fill the gap and caulk over it again. That's
on this weekend's itinerary. So check out the caulking, if you haven't done
There really isn't much caulk. This is a shower stall vs. a tub. The
tiles have unsanded grout between them and between the bottom row of
tiles and the floor of the shower is sanded grout. I put some caulk
around the soap holder in the wall because that was my first suspect
but I taped it up tight temporarily and it makes no difference. The
only other caulk is around the glass door metal frame which seems to
be in good shape as far as I can tell.
As some of the other posters have recommended I begining to suspect
the drain. If not the drain I am wondering about water leaking out
from a valve inside the wall or the piece that attaches the shower
head to the copper behind the wall?
I had a similar problem about a year ago. It turned out to be leaking
grout. The tiles were put on drywall by the builder (permitted by local
code at the time), so the whole shower had to be torn out and re-done.
This time, cement board was used.
Just a thought.

Is this a tiled shower? If so the pan under the base may have failed.
In prior years these were fabricated from tar paper and had a life
expectancy of 10 to 15 years. The newer ones are made with 30 to 50 mil
PVC or chlorinated polyethylene sheet.
If this is the failure mode the repair is significant because you will
need to remove and replace the mortar shower base, and re-tile the shower.
I have a question about this. BTW: that's a great diagram. The
shower is tiled but the floor is not, it's a one piece unit, I don't
think it's plastic. It has a light texture to it.
Would the top piece need to fail for a leak? If all the water slopes
down to the drain I don't see how the failed pan can make a
difference. Is it the pan liner that fails or the mortar? Thanks.
What fails is the membrane which is usually sandwiched between two
layers of mortar. Since you have a one piece base you probably don't
have a membrane so another possibility is that the seal around the drain
has failed. Is there any possibility that there is a crack in the base?
Are the tiles above the base well grouted and sealed? Is there a leak
where the tile and the base meet? I have had all of these failures over
the years and they are not fun to repair, primarily because it is
difficult to determine where the failure is without wrecking out the
shower. You could try removing the grate on the drain and seeing if
there is a leak there, perhaps a little caulk there will resolve your
problem. Good luck.
Re-reading your original posing I'd hazard the guess that you have a
leak around the drain or a crack in the base and since (I assume) you
weigh more than your wife you flex the base and open up a small void
thus allowing water to pass. It's axiomatic that water will pass
through any opening, no matter how small, if you don't want it to.
