Yuck! Just the very thought of sitting in my own dirty, stationary water makes my flesh crawl.
Which is why, when I got my bathroom redone a few years back, I first adjusted the stem of the plug of the "P-shaped" bath so it would never close properly; then quietly threw it away. Next time, I'm having just a stand-up shower stall (with the option of a wall-hung, fold-down seat; after all, I will be fifty by then), building a stud partition wall and moving the washing machine to there. It will be safe because the electrics will be well out of reach of the shower, and more hygienic than carrying my dirty knickers and sweaty socks through the kitchen where I cook food, and it will also mean I will have room at last for a dishwasher .....
