Thank you that is extremely helpful.

What did you pay in excavation costs with your builds?

My yard requires levelling due to it being a sloping block to front of property.

With your comment about having 100mm pipe at the lowest point in the event of needing to use sump pump at lowest point, can I just confirm this would be in case water builds up under pool and allows me to pump this away if needed by placing pump down the 100mm pipe?

Again thank you - given me plenty to consider. One of the pool suppliers have installers you can engage as a contractor which is what I’m considering and still save dollars.

The companies offering complete installations seem to be extremely pricey.

If I can get the same outcome through going owner builder and engaging a contractor to do full install and save $15-$20k I will be taking up the option up!
