Modin Rigid is 100% waterproof, and is ideal for bathrooms. If installed correctly, the click mechanisms will prevent standing water from reaching the sub-floor for as long as 24 hours, usually long enough to allow evaporation.
A little water reaching the sub-floor is nothing to be concerned about in general, as it too will dry out and evaporate. However it is advisable to use caulking at the ends of the flooring, especially where the floor meets a bathtub, toilet, or sink, so that in the event of flooding the subfloor doesn't get fully drenched.
