Just wondering have any tried changing to those hand held shower things - they come with an attachment for up at the shower head and the length of hose.
some have longer hoses too or you can get extensions to add length.
Ours has 5 or 6 different spray options - some have 10.

plus you will have better control over where the water hits you and you can sit on a chair or stool if needed.

Get the mid priced ones or higher or they will not last long or leak.
