Most manufacturers state the unit can be fitted anywhere within a shower area so long as the unit is above the water catchment area and leaves a gap greater than 200mm between the top of the unit and the ceiling.
Some mention is made about positioning away from the direct spray area. The units are waterproof, but clearly it would not be sensible for the unit to be constantly heavily drenched.
The shower should be positioned as high as possible but consideration should be given to young children who need to use the shower safely.
Usually, I like to fit the bottom of the casing about 5' above the shower tray.
