I frequently exit my Wetsuit after surfing, inside my van, but often right next to it if it is warm enough outside.
I have a thick door mat just inside my side doors, that can trap lots of liquid moisture:

This however took quite some time outside and several scrubbings before the toxic rubber stink dissipated enough to keep it inside the van, but now I love it for the entrapment of dust dirt and liquids and I can no longer smell it. I think nothing of letting wet shoes rest on this mat, or even my wet wetsuit in a pinch,
My land based wet gear is a pair of MeindL hiking Boots with Vibram soles which are waterproof to about 4 inches deep, and a Goretex Rainjacket both bought in NZ 15 years ago. I've nothing for protecting my legs though.
I hang my wetsuit folded in half over my front passenger side footwell on a special hanger I made for the task. The drips into a ~7 quart oil pan that I keep pretty sterile. I have an adjustable speed fan I can aim at the hanging wetsuit.
My ceiling also has lots of attachment points , in the form of rope cleats.
Sometimes I leave the laundromat before all my clothes are fully 100% dry, and then hang them all over my Van and keep the fans going until they are ready for folding and storage.
My roof vent does pretty good at keeping the windows from fogging up in my mild climate, but when I close it up for the cold spells, I need to use a squeegee on the window interiors the next morning.
The rinsed but still salty wetsuit hanging in the passenger footwell is hard on the nearby Dodge fuse block inside the glove box. I had serious oxidation impeding electron flow on the glass fuse 'claspers', that took significant effort to remove, so as to return function to brake lights and to prevent issues on all the other fused circuits too.
Today was all rainy and damp. When driving I had the heater on high and all my internal fans pushing the somewhat drier heat everywhere to help dry it out inside.
