Hi K1,
If the Electric underfloor heating is installed to the manufacturers instructions and wired correctly, and your household Electrics are up to modern standards , then I cannot see how it could be termed dangerous by your Spanish Builder.
Electrical Regulations in the U.K. are much more onerous ,in terms of compliance with Electrical Safety , especially in Bath and Shower rooms and , as you say, underfloor heating is certainly commonplace and completely within the Regs.
To highlight this compare the amount of power sockets you see in UK bathrooms, do you see any ? Now compare it to Spanish bathrooms, Yep you see them and usually right next to the sink too, which that Spanish builder would be more than happy to install
