Not sure where to buy the shower unit itself.
Just to add to my previous reply. In the UK for example a 10kw shower would be wired from the main supply, in 10 sq.mm twin & earth cable, with a 45amp circuit breaker and a double pole pull switch located near the shower unit.
A 10 kwatt shower on full would draw around 40amps from your incoming supply, so you need to bear this in mind.
Generally in Spain, electricity contracts deliver a set amount of supply current. The amount of current is what the customer has requested and should be written in the contract. The amount of supply current can be upgraded at customer request - to the Electricity company.
If a customer switches on too many appliances within their dwelling which is over and above the contracted amount, then your supply will trip off until the load in the dwelling is brought down to within the contracted limit.
Hope this makes some sense.
