No shower the shower will be thermostatic just 8 sockets , the only thing I can think is they have a walk in wardrobe where could possible be a hair dryer and other things like tht on at the same time , but I’m thinking taking a 10mm t+e to a sub consumer unit which will be fitted close by to the existing CU and won’t be buried fit an RCD protected 2way CU one sockets for sockets one for lights ?I guess the point is you can have T&E without RCD protection so long as it is not hidden < 50mm from a surface.
Feeding a CU off a 32A MCB works, but is not terribly good either as any big fault is likely to trip both the CU and the feed MCB, but again depending on what is needed that may or may not be a concern. Certainly I would be looking at a couple of RCBO in such a 2nd CU to reduce the chance of something on the sockets also taking out the lights.
But what is lacking here is the design aspect - what sort of load(s) are expected, etc. If it is just lights & sockets then a 32A feed is plenty, but if there is going to be an electric showed that suddenly looks small.
