what trade do I need to replace an old shower unit ? (not the cubicle )

Stupid I know - is it an electrician ?

Shower bit is more than 20 years old ,should I be expecting major re wiring as well ?

A plumber/bathroom fitter should be able to do it but yeah an electrician to be on the safe side

Thanks MrsJ ,I think probably an electrician too .

Electrician.
