Adam is Building a DIY Hot Tub with ICF Blocks: Let’s follow his journey

ICF Hot Tub? Have you ever dreamed of having your own hot tub in your garden? If so, you’re not alone. Hot tubs are a great way to relax and unwind, and they can also add value to your home. But what if you don’t have the budget for a pool or spa builder to come and build it for you? That’s where DIY comes in!

In this blog post, we’ll be following along with Adam, a DIY enthusiast who is building his own ICF hot tub using ICF blocks. ICF blocks are insulated concrete forms, which are becoming increasingly popular for DIY projects. They’re lightweight and easy to work with, making them a great option for beginners.

Preparation

Adam has just finished the build on his new home and what he wanted was to add a hot tub to his back year. Given the space available, this was going to be a custom design project as the designs that I have in my online store, just were not the right dimensions.

Step 1: Digging the Hole

The first step in any hot tub project is digging the hole. This is a backbreaking job, but it’s important to make sure the hole is big enough to accommodate your hot tub. Adam’s hot tub is custom-designed, so he had to dig a hole to fit the exact specifications.

Step 2: Laying the Concrete Slab

Once the hole is dug, it’s time to lay the concrete slab. This will be the foundation of your hot tub, so it’s important to make sure it’s level and stable.

Step 3: Installing the ICF Blocks

Now comes the fun part: installing the ICF blocks! ICF blocks are like giant Lego blocks that you can easily snap together. They’re made of expanded polystyrene, which is a type of foam that is both insulating and lightweight.

Step 4: Adding the Plumbing

Before you add the rebar, you’ll need to add the plumbing. This is a crucial step, so it’s important to get it right. The plumbing will carry the water to and from your hot tub, so you’ll need to make sure it’s properly installed.

Step 5: Rendering the Surface

Once the plumbing is in place, it’s time to render the surface of the ICF blocks. This will give your hot tub a smooth, finished look. There are many different rendering materials to choose from, so be sure to do your research to find the right one for your needs.

Step 6: Waterproofing

After the rendering is dry, it’s important to waterproof your hot tub. This will protect it from the elements and prevent leaks. There are many different waterproofing products on the market, so be sure to choose one that is specifically designed for hot tubs.

Step 7: Building the Control Room

The control room is where you’ll house all of the electrical equipment for your hot tub. It’s important to make sure the control room is large enough to accommodate all of the equipment, and that it’s properly ventilated.

Step 8: Water Testing

Before you tile or finish your hot tub, it’s important to water test it. This will help you identify any leaks or problems. Once you’re sure there are no leaks, you can go ahead and finish your hot tub.

Adam will be doing this next so do check back soon for an update on this project.
