Hi Gene, I was in the spa today and remembered to take some pictures to send you. This project took a little bit longer than expected but that was mainly a result of the patio area. The actual building of the spa was fairly easy, all because of your guidance. Thanks again for all your […]

I found Gene’s website online after getting little-to-no response from local pool builders to renovate a dilapidated 1940’s pool and add an in-ground spa. After reading Gene’s book and watching his videos, I convinced myself I could do the work myself.  Gene’s assistance in the design, equipment order, and support through the building process was […]

Everyone that soaks in our new, amazing hot tub says “I can’t believe you built this yourself!”. Gene was with us every step of the way as we went through the process of building our own hot tub. We’ve learned so much from Gene’s DVDs, books, and incredible responses to emails and phone calls. He makes […]

“The spa construction methods offered by Gene Trumbull and Custom Built Spas are comprehensive, easy to follow, and truly do allow home owners with average tool using skills and a little common sense to build a spa that will rival anything out there.  The initial purchase of the spa equipment pack and construction manual are only […]

Our new hot tub is a GREAT addition to our backyard and your instructional DVD’s, equipment ordering and advice by telephone made it all possible. Thanks so much again for being the real deal.

We ended up with a spa that exceeds what we had dreamed. If you have a little imagination and some determination, Gene can provide the know-how! Thanks to Custom Built Spas we now have a dream spa in our own back yard!

In meeting with Gene the very first time, I was convinced that I would not be misled or disappointed. His level of expertise and knowledge in Spa Construction was always provided and conveyed to me during the entire process with exceptional customer service. I felt that while I was building my Spa, Gene was like […]

Our home had an old Foxx in-ground vinyl pool that required repairs on a regular basis and as it was nearing 40 years in age it needed to be “retired”.  Not ready to give up on having a backyard water feature we considered our wish list: no need for 28,000 gallons of water with an […]

I was very excited to find your web site, which used concrete block as a base. Since, I am a bricklayer; it was easy for me to install the base of the project. The work was done by me, my wife and my son

Thanks for everything Gene! We couldn’t have completed this project without your guidance and support! Here is a listing of just a few of the project’s details. The ports along the south side allow water to spill over into a basin that flows to a sump at the northeast corner and then is returned into […]

I can without a doubt state that no matter what problem I encountered, Gene was with me every step of the way. His unconditional support is a big part of what makes my renewal room the most beautiful and revitalizing spa I have ever been in. I have been in spas all over the world and am convinced that Gene and I built the best!

I had never built a homemade spa of any kind before, and living in a northern climate knew I couldn’t afford to make too many mistakes.  Gene helped set me up with all the stuff for my spa including laying out how the piping worked etc (I really had no clue).   Of course, more importantly, […]

After doing a search on the Internet for information about spas I found Gene’s Site and ordered just to see if building our own spa would be an option. After reading through it did seem like this could be a good option for getting a better spa at a price we could afford. It is […]

Without Gene’s exceptional knowledge and service, this project would not have been possible.  Everything is laid out in the book very clearly,  If an issue arises, Gene is always available to help until the problem is resolved via email or phone, an outstanding experience. -Greg R. Ontario, Canada

I would not have been able to tackle such a large project without your help and manuals

Tony F.

What can I say, Gene’s materials and supplies arrived on time, were of the highest quality and most importantly, he was always available throughout the process. His knowledge and skills are unsurpassed! He handles your questions and issues with respect and practical solutions that are invaluable. This is a great project for a do it […]
