I’ll go first. After your turn the water off in the shower but before you get out, use your hands to wipe off any standing water on your body. Maybe even give your legs a bit of a shake. This way, you won’t drip nearly as much when you get out, keeping the floor and your towel drier.
Yikes! Glad you’re ok. A friend of mine had a much less dramatic hit by a car but landed on her head and had a lot of difficulties from it.
