This would be classed as a new installation and should be wired by a QUALIFIED electrician and a certificate obtained.

Note V x I = VA not W.... You need to know the Kw rating of the shower. A 9kW shower will draw ~ 39A at max. Note your wiring and CB rating must comply with the shower spec. If you are unsure leave well alone.
Note - 30A cable = 5.8kW safely.

if the shower is rated at 7KW which is quite usual the 30amp cable should be OK. If you need to ask this question, then you are obviously not familiar with electric wiring. As a shower is a critical piece of equipment then I should be very, very careful as you could have a dangerous situation.

Somewhere on or inside your shower will be a label telling you the power consumption of the unit. It may even say how many amps it draws. If you only have power rating eg. 4Kw. Then you can work out the amps drawn thus:-
Amps = Watts / Volts for example Amps = 4000 watts / 240V = 16.67 Amps.

Power = volts x current
Domestic supply is about 240 volts, so at 30 amps it supplies 240x30 = 7200W or 7.2kW
