Maybe they’re counting, or not, walk-in tub use some weird way - people that use handheld shower heads while sitting?
The few years of my father’s life, he needed one of those half-in/half-out tub benches for showering, and for getting in & out. As his fear of falling grew, he showered less frequently, and he’d occasionally reek.
