I found drinking water from the tap not that enjoyable, and the bottled stuff would be expensive/prone to plastic ingress.
I realise I might take some stick for this.. but there is an Ayurvedic practice of storing water in a copper jug for a couple of hours before drinking.
I now keep a copper jug by the kitchen sink, fill it up when empty and decant water to drink from it as needed.
Regardless of any proposed Ayurvedic benefits which I know zero about, I can say (in my experience of about 3yrs now) it
does make the water taste somehow 'smoother', creamier even. I no longer have to force myself to drink water - because it now tastes better.
As I said I know this sounds like Youtube whooo but all I can say is that adopting this practice (storing water in a copper jug and decanting from there), allowed me to significantly increase my water intake as it tastes somehow... err.. less shite.
So I'm putting this here as an idea for anyone who finds it a mission to make themselves drink tap water
