    If the grout is in good condition, you can try to seal it with a clear epoxy sealer or paint it with epoxy paint. But this may only be a band aid fix. What is the tile glued to? What kind of subfloor is under the tile? You may have damage under the tile. A membrane, either roofing felt or rubber, should have been installed over the subfloor before the tile was installed.

    Thank you for your response...we will try the epoxy, but I think you are right about the subfloor. We have it on concrete, but we bought our place after it was installed and I agree with you it should have been put down over a membrane. Will try epoxy for a quick fix. Thx again.

    Pay particular attention to the edges of the floor especially where it meets a wall. This area should be caulked using an exterior grade rubberized caulk (allows for expansion and contraction).
