In our bathroom in front of the sink cabinet about 6" is an oval wet spot 10" x 5" & a smaller spot now appearing next to it. The house is on a crawlspace I went under there and could see no leakage in there. I couldn't see any water inlet so I imagine it maybe above the insulation in the crawlspace which I didn't remove. Could this be a drainage leak? Or, should I remove the insulation below this leak and see if I can see anything? Help, need help. Thanks
