How to Build a Sauna: Step-by-Step Guide

1. Plan Your Space

So, how do you a build a sauna? The first step to building your sauna is careful planning.

Choose Location: Decide whether you want an indoor sauna or an outdoor retreat. For outdoor saunas, ensure the area is level, weather-protected, and has access to power. Indoor saunas should fit within unused spaces like basements, bathrooms, or spare rooms.

Determine Size: Think about how many people you want the sauna to accommodate. A compact two-person sauna is ideal for small spaces, while larger options are great for families or entertaining.

Select Style: Choose between a traditional sauna or a DIY infrared sauna, depending on your preferences and available space.

2. Gather Materials and Tools

Having the right materials and tools is essential for a smooth build.

Timber: Use sauna-grade wood like cedar, spruce, or hemlock for durability and aesthetics.

Insulation: Invest in high-quality insulation and vapour barriers to ensure heat efficiency.

Heater: Decide on the type of heater—electric, wood-burning, or infrared.

Accessories: Include sauna stones, benches, lighting, and thermometers to complete your setup.

Tools: Prepare tools like a saw, hammer, drill, screws, level, and measuring tape.

At SDS Australia, we provide a curated selection of premium materials and accessories to make sourcing everything you need simple and convenient. Contact us today and we’ll put together a list of DIY sauna essentials that will meet your needs.

3. Build the Sauna Frame and Insulate

This step involves constructing the core structure of your sauna.

Construct the Frame: Use your chosen timber to build the walls, roof, and floor of your sauna. Follow your design plan carefully, ensuring the structure is sturdy and level.

Install Insulation and Vapor Barrier: Line the interior with sauna-safe insulation and a foil vapour barrier to retain heat and protect the wood from moisture.

Finish with Interior Panelling: Cover the interior walls with tongue-and-groove wood panels for a seamless and professional look.

4. Install the Sauna Heater and Accessories

Bring your sauna to life with heating and finishing touches.

Install the Heater: If you have an electric sauna heater, hire an electrician to install it with professional wiring. Follow the manufacturer’s guidelines. Ensure it is safely positioned and ventilated according to the heater type. Wood-burning heaters need a chimney.

Add Benches: Build and secure benches for seating. Use heat-resistant wood that remains cool to the touch.

Incorporate Accessories: Add essential items like a thermometer, hygrometer, lighting, and a bucket and ladle for a traditional sauna experience.

Safety First: Ensure all components, especially electrical wiring and ventilation, meet safety standards.

5. Finish and Enjoy

After assembly, inspect your sauna to ensure it functions properly and safely.

Test the Heater: Run the heater to verify it heats efficiently.

Personalise Your Space: Add towels or aromatherapy oils to make the sauna uniquely yours.

What Our Customers Say

I’m a home DIYer building my own sauna at home. The team at SDS have been amazing. Prepared to give me plenty of time and advice. The team at the Epping warehouse were happy to give me advice building my sauna from scratch and gave me plenty of helpful tips and knowledge. The team over the phone have been incredibly helpful too. I called with an amateur issue whilst attempting to install my sauna heater and within minutes Phil had connected me with their electrician who was able to speak with my sparky to help with the install. You don’t often come across businesses and people like this who are genuinely helpful. Keep up the great work guys!!!
