[Question] Upgrading rental apartment-Single Handle Shower Handle

[Pixel Rogue]

Converting 3-handle showers to single-handle showers. These are rentals, so looking for your advice. Units that will last, hold up to tenant use; ideally spot free.

Not sure if to stick w/simple single operation style (on/off), or go for the dual handles that operate temperature separate from water flow. Looking for a model that will hold up to tenants that over clean, and those that never clean. Model that is not too fussy, easy to open up and repair when needed. The building is slowly being upgraded to luxury style apartments (well, luxury for the area, not luxury by real-estate terms). So many of them appear to also be plastic painted to look like metal.

Anyone gone through something similar and happy w/what you installed? Also, any particular remodel cover (escutcheon) plate you've been happy having installed?

TIA.
