My recent experience is to suggest that you think as well as look very carefully at the types of shower enclosure. What type of door – pivot, sliding, folding?
As an example, I had an Ideal Standard offset quadrant enclosure fitted. It looks fabulous with curved glass and sliding doors which still work beautifully. However, all I can say is that it must have been designed by someone who had never cleaned anything before, too many nooks and crannies that are difficult to keep clean.
If I were you, visit some bathroom showrooms along with the person who’ll do the cleaning of said enclosure, if that isn’t you.
Mira showers are good, I love my thermostatic one with a start/stop function which reduces my water consumption.
