Pool in the garden? - Need inspiration!

Does not change anything about the connections and disconnections. Water, electricity, sewage still need to be installed. A hole is also required…

We will also get a pool. The pool builder said sewage is not necessary. Just pump it out.
Electricity should be laid at least twice 3x2.5 for heating and technology.

And where does the water from the backwash go? Emergency overflow?… I think you’ve got yourself a "specialist" there. No decent pool builder would make such a statement. Sorry if I’m being so direct. 3x2.5 is also the joke. Depending on the heat pump, counter-current system, lighting, cover, that’s not enough either.
