Hope you can help.
Shower floor grout looks wet.
Epoxy grout is the best choice for showers because is water and stain resistant and requires no sealing.
The bathshower sits on normal wood floor boards while the tiled floor sits on protected plastic water proof base.
Ft shower is 5 by 3 there is a very strong fan that is on timer and is on for 30.
Its a large bathroom approx 150 sq.
Had the guy who remodeled the shower come look at it.
If this isnt the case with yours you should allow grout to dry completely clean it with a small rotary wire brush a little dremel works great.
48 hours later the spots are still looking wet but are not wet to the touch.
It is a new build first floor bathroom new extension on older house with a.
The spots started spreading until the whole floor of the shower has dark colored grout although it is not even.
The wet area is not caused by using shower as the shower screen protects this space.
Some grout has a sealer additive already in the mix.
So i decided to use another bathroom in the meantime.
The floor is tiled with large 60x60cm porcelain tiles laid on impey waterguard membrane and the shower tray is impey aquadec easyfit with the membrane laid over the top.
The tiled floor has been laid for about 2 years and this problem has only just occurred in the last few weeks.
The contractor told me the shower is bullet proof however the grout looks wet and looks dirty.
He opened the wall to adjacent closet in the next room to assess the shower pipes and no leaks found.
Keep in mind the lighter the grout the more it darkens simply from the humidity of the shower.
We had a wet room installed about 8 months ago.
As soon as we started using the shower the grout again started darkening like it was wet.
