The supply and the Consumer unit would only be overloaded if..

1: Your supply from the Mains does not have a 100A Fuse in the head.

2: You run everything at full power at the same time or,

3: The Shower and water heater are running at the same time with any other high load appliances, such as washing machines, Kettles, tumbles dryers etc.

The maximum potential load of most consumer units and distribution boards, (The total of all the MCB's etc installed in it) quite often exceeds the rating of the Isolator or RCD, whichever is the main switch.

This is no need for concern normally, and so long as common sense prevails never will be.
