A bit difficult for me to dismantle the whole thing because I also need to check the tenant's timing. How much would you think the item with shower head cost? I was quoted Rm300 without labour.
It's a livinox andora model but I could not find anything relevant by google search about the spare part (valve or shower set)
The components of the rain shower set are usually unique to their own brand / supplier. Hence u should check back with the instant water heater brand if u can just purchase the spart part u need (in your case it is the rain shower diverter).
If u can't get the parts u need from the instant water heater brand, then u have to purchase a new (whole) rain shower set. There are usually 2 kinds,
1. standalone rain shower set - meant to be used with hidden / storage water heater, it has larger nozzles with higher water flow. Usually doesn't come with separate shower handset.
2. instant water heater rain shower set - meant to be used with instant water heater, has a separate shower handset.
Since you are using an instant water heater, u should get the option 2 kind. Here is one example -
