I know exactly how you feel. It must be the heavy periods that might be causing your annoyance with the flow and cleaning. To tackle bath issues, what I used to do when I had heavy periods due to fibroids was that I had my napkin set in my panties ready to put on as soon as I showered. I used to quickly dry the bottom half and wear the panty and then carry on with the rest. I know how it must feel if you have showered and then the floor gets messy before you dry yourself or the bath mats might get messy too. To avoid this I used to do this step immediately so that even if the shower stall is messy within that minute, I can rinse it away, but getting it on the bath mat would be terrible so I used to avoid that. As for bucket taking long to fill up, don't you have something called a toe tester or a tub filling spout which is an option for shower systems? I am doing a bathroom reno now and I insisted on getting this extra option for the shower system. I will let you know when the reno is over as to how fast the water fills up.
