Hot tub starter kit

This kit contains everything you need to get your spa set up for use. The instructions are clear, and easy to follow. So for I've only needed to use the chlorine, but the other chemicals are there for when we need them.

Thank you

I have acute anxiety. Since purchasing our hot tub, my anxiety levels have plummeted lower than they have in years.
It's quite honestly the best purchase I've ever made.
From ordering to delivery it's been nothing short of perfect.
It's easy to install and easy to maintain.
I honestly cannot fault it!
Thank you.
