Outside the cubicle! No room to duck out the way! Time enough to check your weight! Obviously we redesigned the bathroom when we got rid of the bath. We have lovely cupboards surrounding the basin, so you can hide all those bits and pieces. But I would sacrifice that not to have a cubicle difficult to clean. We will do it one day as when you get older it helps to have room for a seat. Or if you break a bone as DH did a couple of years ago. You learn by using what works well.
I've been washing with Epidaderm emulsifying ointment recently. I have very dry skin and washing with cheaper emulsifying ointments instead of shower gel really helped, but started to find they irritated my nether regions, so I did some research......well, read the ingredient list more carefully! Contains SLS. More expensive ones don't, so tried this one and no irritation.
