Ok, but why not leave all the water in the spot that actually has a drain for it?
I believe wet bathrooms have a drain in the middle of the bathroom. This is the way we should build all bathrooms.
Bathrooms should have a floor drain regardless of whether they are of the wet variety. I personally hate the concept of a wet bathroom and the behaviour it encourages. Stuff gets wet that shouldn’t, it just makes everything harder and expands the scope of cleaning while compromising “dry” tasks after someone else has used the shower if they partake in the undisciplined behaviour the design encourages. Also not a fan of all the functions being in one room.
After you’ve skimmed the water off, then towel dried inside the shower, the bathmat barely needs to get wet, especially if you step onto your towel when getting out.
