basement finishing

Hi,

I bought a new house in Toronto last month.
and I'm planning to shift within a few weeks with my family.

Before shifting I'll have to do some renovation works. I'm also thinking about adding a pol in the backyard. Because we got plenty of space unused in the garden.

Already found a nearby swimming pool design and building company. I really liked a few designs they have shown.
Will finalize one soon. I'm also planning to add multicolour LED lights inside the pool, so I would like to know what are the things we should keep in while doing the wiring. If anyone installed LED lights inside pool, please share your insights.
