Gas heat for hot tubs? What is that all about? Hot tubs are a fantastic way to relax and unwind after a long day or week, and there’s nothing quite like soaking in warm, bubbling water to soothe sore muscles and calm the mind. But while hot tubs are a popular and beloved addition to many homes and properties, they do require some maintenance and upkeep to keep them running smoothly and efficiently.

One of the most important factors in maintaining a hot tub is ensuring that the water is heated to the right temperature. The ideal temperature for a hot tub is generally around 100-104 degrees Fahrenheit, but achieving and maintaining this temperature can be a challenge, especially in colder climates or during the winter months.

What is the Cheapest Hot Tub to Build?

DIY Stock Tank Hot Tub Kit

Everyone wants to know what the cheapest hot tub to build is. I’ve been asked this question many times, and here’s an answer that paints a complete picture.

Before proceeding, let me clarify what a hot tub is. I’m not talking about those holes in the ground heated with fire. That’s not what I’m about. My definition of a hot tub is one that has a pump, a filtration system, jets, and the other things that come with a hot tub.

Before moving onto what the cheapest hot tub is, let’s look at which ones are far from cheap.
Plastic shell tubs, block or concrete builds, and in-ground hot tubs are far from cheap. They require significant work and time to build and require custom plumbing and so much more.

Cedar, timber, or other lumber has also become a costly option due to the high cost of wood over the past few years.

The cheapest hot tub is also my second favourite, right behind the in-ground block or concrete hot tub. This is a stock tank hot tub. It is also known as a hillbilly or cowboy hot tub. These hot tubs rely on an animal feeder as their central basin, making for a very cool and simple setup.

DIY Cold Plunge + Hot Tub Combo? Kyle’s Backyard Wellness Center

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.
