The old water heater worked fine. The key word in that sentence is 'old'.

If I had known all I needed was some pies, I would have gladly baked a few. ahahahahaha
I sold my new home a few months ago and downsized to an older home. I've been doing some upgrades. The water heater was 12 years old. That's about the standard life span of a water heater over here. It's possible it could have lasted longer. A well known plumbing biz 'Roto-Rooter' quoted at $1,729.00. I went with a local small family plumbing biz and paid $1,158.00. That's for the new water heater, pan, install, everything.
Water heaters are somewhat complicated. I have an electric water heater. A gas water heater involves much more work.
Australia, the plumbing may be different for faucet connections. Over here, I would simply turn the water connection off, remove the old faucets, remove the water lines from under the sink, screw/replace with the new water lines under the sink, attached to the new faucets, and turn the water back on. Normally you will have cut offs under the sinks to turn the water off to that sink. That would be in the form of a handle or a knob that you either flip up or down or turn left or right to disconnect and connect the water flow. I've used a hole saw to cut out additional holes for at the sink when needed such as for dishwasher, sprayer, or soap dispenser. Changing out faucets in sinks, is very easy. The problem might come into play if it is a shower/bath faucet without a good access panel and no shut offs.....you'd have to shut the water off at the main.
You may have forgotten, my husband was a contractor. He built houses. We built our own house. I learned a lot from him over the years. Altho he was not a licensed plumber, he could install water heaters. Altho he wasn't a licensed electrician, he could run wires. In the USA many States require a license for work such as water heater installation and electrical wiring. He did the work when we built our house and simply had a licensed plumber and licensed electrician approve the work.
