A DIY Cold Plunge and a hot tub combined? Is that even possible? It certainly is and in this article, I will walk you through a project that I designed for Kyle in the USA.

The Requirement

The client, Kyle, contacted me a while back regarding designs for a hot tub that can be converted into a cold plunge and vice versa for the wellness centre he was building on his property.

I’m calling this a wellness centre rather than “an extension” because you will see in the images below, the end result with cold plunge, sauna and steam room looks more like something you find in a high end hotel than in your back yard.

Kyle knew what he wanted and gave me specifications such as massage jets, the ability to stand in the cold plunge, and, of course, the ability to convert from one to the other.
He asked me to design these plans, and I created the concept for Kyle.

We’ve been following the progress of Paul in the UK and his DIY hot tub for some time on this blog and my YouTube Channel.

In this video, Paul walks us around his hot tub and explains some of the features and intricacies of the design.

Today, I’m excited to share an incredible DIY hot tub project with you. John, from Kentucky, is building an 8×8, 14-jet hot tub in his backyard using one of my pre-designed plans. Let’s dive into the details!

While many of my case studies focus on custom-designed hot tubs, today we’re taking a look at a more straight forward project. John from Kentucky has chosen to build an 8×8 hot tub using one of my pre-designed plans.

This approach offers a great starting point for DIY enthusiasts looking to create a relaxing oasis without the complexity of a custom design. Let’s follow John’s journey as he brings this off-the-shelf plan to life.

Paul decided to take the plunge (pun intended!) and build his own hot tub, and I’m excited to share his progress in this blog post.

We opted for one of our standard designs from the buildahottub.com store – these are a great way to save money and still get a fantastic hot tub, especially if you’re handy and want to customize it a bit. You can find links to all the standard designs here

Darren got in touch with me April 2024 because like most of my customers, he had been quoted an astronomical amount of money to build a hot tub come swim spa. 

The conversation always goes the same way “I spoke to several pool builders and the quotes that I got were outrageous” he began. “I think I can do this myself with your help” – well Darren you have come to the right place I replied.

From there, we had a good chat about the specification and features he was looking for and then it was time for me to get started on the initial design renders.
