We just recently moved into the house we bought 5 months ago.( house was built 8 years ago). Before we bought the place we had it inspected by a top inspector in our area and he was excellent. The stand up shower we have is made with Travertine stone tiles all throughout. I notice a musty like smell every time I take a shower( it seems to be coming from the tiles). There is no smell when the shower is not in use, it is only when I am in there and the water is on. It may be the stone tiles themselves, I am not sure. We use to have just ceramic tiles where we use to live, so the stone tile is new to us. We clean the shower weekly using just borax and hot water. I am super sensitive to chemicals so I try and use more non-VOC and low odor products.
We went out and bought a moisture meter ( By General). We wanted to make sure there was no moisture behind the tiles. Now with moisture meters, how exactly do you determine what is to high? Also, is there anything that can cause the reading to go high besides water/moisture in certain areas of the shower? When checking the shower bench inside the shower, it showed 100% reading on the meter, in every spot we put it on that bench. Also, in our downstairs basement shower, the reading on the floor of the shower was also at 100%, again, that was in every place we checked on the floor of the shower. I am just wondering if anything else( concrete, metal) could make this reading be this high? I know when we had our inspector out here he checked everything. He also did moisture checks and they were okay at that time, but again, I was not in there when he was checking. Just wanted your opinions. Thank you much.
