Grout on bathroom floor looks wet

I would have a flooring person look at it, because if the shower is leaking, it too will need to be fixed. You don't want to risk mold or if your bathroom is on the second floor of your home, it could fall through the ceiling. t any rate it will need to be replaced.

Check around the toilet and around the tank. Also check the bolts that hold the toilet to the floor. Check the water shutoff because that could be leaking. And lastly does the tank on your toilet sweat when you are showering or bathing. Just one more spot to check before you tear out a wall.

First you need to find out exactly where the water is coming from and deal with that. Depending on how long the leak has been there will determine if the floor needs replacement. The plumber may even be able to tell you if the floor is ok or not. If he can't, you have to call a contactor to check it out and replace it.

Is the grout actually wet, or does it just look wet? There are some types of grouting that do have more of a shiny 'wet look' to them. They are smoother, glossier, and do not contain as much grit as the 'dry look' types.

You might try a moisture meter on your tile after having not used the area for several days to see it it is truly wet. If it is after not having used it for a period of time, you'll need to get the problem taken care of as mold and damage may be occurring.

Remove grout and look to see if it looks wet or use toilet tissue to see if any wet can be wicked up!

If there isn't a spill or other source of moisture above the tile surface, it must be coming from underneath the tile. If there is only one little place where the water is visible and it is coming from beneath the tile, it must be coming from a sink or shower.

Does it look wet or is it actually wet? The grout could have been sealed with something glossy. Or, you could have leaks. I’d have a pro come out and assess for you, probably more than one as not everyone is as reputable as they should be.
