Yes you can... but you'll need honest help!

Custom Built Spas is a Connecticut-based veteran-owned business established in 1999 by Gene Trumbull. Gene understands the desire and satisfaction fellow DIY (do-it-yourself) enthusiasts feel by being able to construct different kinds of projects by themselves.

What he also came to understand when he was looking into building his own hot tub was simply this... there was virtually no quality DIY information available anywhere for doing this type of project! Oh, sure, you could find a few videos on YouTube with all kinds of crazy ways to construct a spa or hot tub.

Armed with all that knowledge, Gene made it his mission and desire to turn building a spa or hot tub into a very doable, high quality DIY project, not only for himself but for other DIY enthusiasts as well... a mission successfully repeated over and over again for nearly two decades!
