DIY Hot Tub - Step by Step Guide

Making a wood-fired hot tub can be an enjoyable and rewarding project that adds a luxurious touch to your backyard. This comprehensive guide will help you through the process step-by-step, ensuring you have a reliable source of warmth and relaxation. Before starting, it's important to gather all necessary materials and understand the steps involved.

Materials and Tools Needed

169-gallon galvanized steel stock tank
Gravel, sand
Scrap melamine for footings
Fast-setting concrete mix
½-inch copper tubing (about 20 feet)
1-inch by ¼-inch thick steel bars
Tank fittings, compression fittings
Silicone sealant
Drill, hole saw (1 and ⅜ inch diameter)
Jigsaw, sander
Firewood
Lighter fluid (optional)

Step by Step Instructions

Step 1: Preparing the Foundation

Choose a suitable spot for your hot tub, ideally level and close to a water source.
Make footings for the tub to prevent sinking. Use scrap melamine to form molds for the concrete and pour in fast-setting concrete. Ensure levelness.
After the concrete cures (about 24 hours), remove the molds.
Add a layer of gravel for drainage, followed by a layer of sand for stability.

Step 2: Making the Heating Coil

Take the ½-inch copper tubing and wrap it around a five-gallon bucket to form a coil approximately 18 inches tall.
Cut steel bars to size for braces and drill holes to bolt them around the copper coil.
Drill holes in the stock tank and secure the tank fittings with silicone.
Attach the copper coil to the tank using the fittings, ensuring it is firmly secured.

Step 3: Setting Up the Coil

Position the coil near the hot tub, driving the steel bars into the ground for stability.
Conduct a test fire to ensure water circulates through the coil and warms up as intended.

Step 4: Building the Lid

Make a lid from ¾-inch thick redwood to retain heat. Ensure it fits the curve of the tub.
Cut and sand the wood, adjusting for any moisture.

Step 5: Heating the Water

With everything set up, start a fire using the firewood.
Heat the water to your desired temperature, keeping in mind it may take a couple of hours to reach an optimal 104 degrees Fahrenheit.
Stir the water occasionally to distribute heat evenly.

Maintaining Your Hot Tub

Regularly check the copper tubing and fittings for any signs of wear or damage.
Keep the area around the hot tub clean and free of debris.

Safety Tips

Always supervise the fire and ensure it is fully extinguished after use.
Check the water temperature before entering to avoid burns.
