how do i fix tiles lifting in shower floor?
#1

I have tiles lifting in my shower floor. The shower is located downstairs in my split level home. I am determined to do the repairs myself, but I'm a first time home owner, and need a step by step "tutorial". Any takers?

These tiles, are they inside the shower pan, I mean, you stand on them while taking a shower? How big are they? How many are loose? Is there any funny looking stuff oozing up in the grout lines between the tiles?
