I recently bought a townhouse that had the upstairs bathroom redone completely with a walk it tile shower. I have been there a year and recently noticed that the grout is slightly cracked around the base (floor and walls). I have also noticed mold that I have sprayed in the grout (Since leaving the door open after each shower got that under control). My question is I recently took a shower last week and had water seep down through a light unto the floor below (half a cup). Do I assume its

A leaky shower pan?

Should I regrout/reseal the grout between the floor and the wall. I have heard that mildew remover weakens grout is this true? And could I have weekend the grout by using this?

Or should I check the drain first then the shower pan?

If I do have to change the shower pan is there a way to save the tile (not sure if I can get replacement)


Thanks

Hi Ryan,

Let's find out where the leak's hiding. We'll check the drain and pan first.
Remove the strainer, TIP: put the screws in the soap dish. They will be difficult to replace if they go down the drain.
Now take wet rags an put then in a baggie and jam them in the drain to seal it off. Tonight before you go to bed fill the shower floor with a inch or so with water and mark the level. Next morning look for moisture or a lowered water level. Let me know what you find and we'll move on to the next test.
I haven't heard that mildew remover will weaken tile grout but I do know that over time tile grout will shrink allowing water to leak pastthe top of the shower pan. Regards, Tom

I tried two of the tests; pouring 2 gallons directly down the drain and then plugged up the drain and filled it with water. I left it in there for a day and a half. Its gone down by about 1/2 inch, but no water marks still. I have read come of the other posts and some water going through the tiles/grout is normal right?


Two things I did notice when I took the plate off the drain. There was a lot of gunk in there. It also appears that the grout around the drain (putting your figures in there) is loose.

Thanks

Hey Ryan,

If the pan and drain test came olut OK then note where the stream, hits the tile. Over time and wear tile grout will shrink allowing water to enter and leak past the lip of the shower pan and down into the ceiling. My advise would be to focus on the tile and regrout. Good luck, Tom
