Why Build Your Own DIY Hot Tub?

Building your own DIY hot tub can seem like a daunting task at first. However, there are several compelling reasons to consider taking on such a project. Here’s why making a homemade hot tub can be beneficial:

Cost-Effective: Commercial hot tubs can be expensive, not only in terms of the initial purchase but also regarding installation and maintenance costs. A DIY hot tub allows you to control your budget, sourcing materials that fit your financial situation and potentially saving thousands of dollars.
Customization: When you build your own hot tub, you have the freedom to customize every aspect of its design. From the size and shape to the type of materials used, and even the jets and heating method, your hot tub can be tailored to your exact preferences and needs.
Personal Satisfaction: There’s a unique sense of achievement that comes with completing a DIY project, especially one as significant as a hot tub. This accomplishment not only provides personal satisfaction but can also be a great conversation starter.
Learn New Skills: Throughout the process of building a hot tub, you’ll likely acquire new skills and knowledge. Whether it’s basic carpentry, plumbing, or understanding heating systems, these skills can be valuable in future projects and home maintenance tasks.
Environmental Control: By choosing eco-friendly materials and energy-efficient heating options, you can minimize the environmental impact of your hot tub. This gives you the opportunity to enjoy luxury while being conscious of your carbon footprint.

Building your own hot tub is not just about saving money; it’s about making something uniquely yours, learning valuable skills, and enjoying the fruits of your labor in the most relaxing way possible.

How to Build a Hot Tub: A Complete Guide From Start to Finish

Building your very own DIY hot tub is not only a fulfilling project but also a fantastic way to add a touch of luxury to your home on a budget. This guide will walk you through the steps taken by a creative couple who built their dream wood-fired hot tub from scratch using unconventional materials. Let’s dive into this transformative journey, turning simple materials into a relaxing hot tub oasis.

Getting Started

Gather Your Materials

The journey begins with sourcing materials. In the showcased project, the creators opted for cedar lumber, known for its resistance to rot and insects — ideal for a hot tub. They sourced the lumber at a great price and set out to ensure all pieces (staves) were clear of knots and blemishes to ensure a smooth finish and a waterproof seal.

Preparing the Staves

The sides of the hot tub, or staves, need careful preparation. Each one should be free of holes or knots to ensure structural integrity. You might need to surgically remove any imperfections. This step is pivotal as it guarantees the quality and durability of your hot tub.

Building the Structure

Crafting Joints

The staves require canoe joints for them to fit together snugly, making a circular shape for the tub. If you possess the necessary tools and skills, you can do this step yourself; otherwise, seek professional help for precision cutting. Next, dado joints are cut at the bottom of each stave to fit the floor securely, ensuring a waterproof seal at the base of the hot tub.

Assembling the Floor

Just like the staves, the floor of your hot tub needs to be free from holes. Any imperfections must be meticulously filled to prevent leaks. After ensuring a smooth, hole-free surface, you can begin assembling the floor, fitting it carefully with the prepared staves.

Putting It All Together

Assembly

Each stave is carefully tapped into place on the floor. Remember, the structure is rather fragile at this stage, so gentle handling is crucial. Once all staves are in place, aircraft cable and tensioning devices, or “tourney doohickey thingies,” as humorously described in the video, are used to cinch everything up, giving structural integrity to your hot tub.

Bench and Stove Installation

For seating, a hexagon bench is constructed with one side omitted to make room for the submersible stove. This design not only offers comfortable seating but also efficiently utilizes space within the hot tub. The stove is essential for heating the water, making your hot tub the perfect place to relax in.

The Finishing Touches

Water System and Sealing

Initially, filling the hot tub with water might seem daunting, especially if leaks occur faster than the tub fills. This challenge may necessitate making a water system to ensure a steady water supply for both filling and sealing the tub. Over time, the wood will swell and seal any minor leaks, making the tub watertight.

Heating It Up

With the structure complete and the tub successfully sealed, it’s time to fire up your stove and enjoy the fruits of your labor. The feeling of soaking in a wood-fired hot tub, especially one you’ve built with your own hands, is incomparably rewarding.
