Power shower top left inlet 8.5kw

Anyone know of a power shower 8.5kw with the inlet at the top left of the casing?
Old unit is triton 80 something that looks very old.
All the ones ive ever done are bottom right side
altering pipe not an option coz no 30yr old patterned tiles left over.
I cant even raise the shower and alter behind the casing coz its allready very high.

Thanks

The Mira Sport has the inlet on the left, not sure if its top left though sorry, can't remember.
