We installed a jacuzzi tub in '01, way before I had symptoms...now I really have to be careful...I have slipped more than once, and grabbed onto the shower curtain...luckily, I was saved.
I do catch my toe on the edge of the tub when getting out...it's higher than our old tub, and I can't seem to get my foot as high as in the old days So I am very careful when exiting the tub...
All I can say is be careful...
Ironically, I can't use the tub as a tub anymore, due to the fact that I'm so stiff that I can't get myself out of said tub any longer...
