Traditionally, hot tubs have been quite costly, but with advancements in technology and easy availability of materials, building a hot tub is feasible and economical.

Things to Consider Before You Begin

Building a hot tub is a tremendous achievement but takes a lot of effort, time and money. Therefore, before you start, you must have a good idea of the size, features and specifications of the hot tub you wish to construct. You should also have a clear picture of where you want to position the hot tub.

Size and Feature

Hot tubs come in different shapes and sizes, and their features range from simple to complex. The most common size for a hot tub is 7’x7′, but larger sizes are available for those who need more space. The features that you want to add to your hot tub might include lighting, jets, a heat pump, and even music systems. Of course, the more features that you add, the costlier it will be.

Step-by-Step Guide to Building a Hot Tub

Now that you have all the tools and materials required let’s look at how you could build a hot tub step by step.

Step 1: The Base

The first step is to build a base that can support the weight of the hot tub. You can use concrete to make it, or if you want something more affordable, you can use gravel. Start by marking out the size of the base you want to build, and then excavate the site using a spade. Once you have dug the area, you can then lay down a layer of gravel. Make sure that you level the gravel, so the base is flat. Then use a tamper to compact the gravel, and finish it off with a sheet of wire mesh. The wire mesh will prevent the gravel from shifting, and it will also provide extra support.

Step 2: The Frame

After you have built the base, the next step is to construct the frame. The frame can be made from any type of wood you prefer, but cedar is an excellent choice as it’s hardy and resistant to decay. You will need to measure the size of the hot tub you want to create and then cut the wood accordingly. The frame should be sturdy, as it will support the weight of the hot tub. You can use screws or nails to secure the pieces of the frame together.

Step 3: The Liner

Once the frame is secured, you can place the HDPE liner inside. The liner acts as a barrier between the wood and water and prevents water damage. The liner should be placed inside the frame and trimmed to fit snugly, make sure to leave enough excess to fold over the top of the frame. Secure the liner with a staple gun around the perimeter of the top of the frame.

Step 4: The Plumbing

The next step is to install the plumbing and jet system. Start by cutting holes into the liner where you want the jets to be. Then install the jet assemblies using PVC tubing. The piping should be connected to the pump, which will circulate the water and run through the controls, filtering, heating and back to the tub. In this stage, you will also run waterline or electric if you plan to power the jets with electricity.

Step 5: The Insulation

Once the plumbing has been installed, you can now insulate the hot tub. You have two options here – fiberglass or foam. Fiberglass is simpler to use, but foam is more effective and long-lasting. In either case, the insulation should cover all the areas that are not covered with the liner. The insulation helps keep the heat in, so it’s essential to ensure that it’s well done.

Step 6: The Finishing

Now that the insulation is complete, you can finish the hot tub with the accessories you like. You can add lighting, music systems, or anything else you desire. Make sure everything you use is water-resistant.

Step 7: Testing

Before finally using the hot tub, fill it with water and switch on the pump. Check for any leaks and make sure the valves are functioning correctly. Ideally, you should also take a test run to ensure the water temperature reaches your desired point.
