DIY Sauna Plans Made From Scratch That Will Wow You
Usually, a sauna project will cost you more than a thousand grand, not to mention the installation and maintenance expenses. But don’t let those things extinguish your sauna dream – you will be glad to know that erecting one from the beginning is not pricey at all.
The following sauna plans are concrete proof. There’s a lot to be done, and it will require tremendous effort. Nonetheless, once you step into your final result, you will realize how worthy it is. The dripping sweat, the smell of wood, the steaming hot rocks – it’s everything!
1. Wood-Fired Sauna
Winter is a wonderful opportunity to gather around the fireplace with your loved ones. If the fire does not seem to help carry the cold away, this wood-fired sauna will do the job. In just 25 minutes, it heats up to 150F – pretty impressive, right?
2. Cedar Barrel Sauna
If you are looking for a sauna plan that finishes in less than three days, this is it. The sauna requires no special insulation, flooring, or roofing and is made of Western red cedar. Although it looks humble, you will be surprised to know that it welcomes 4-6 people.

3. DIY Sauna And Hot Tub
Self-care is more than just having a glass of champagne and lighting up the candles. Take it up a notch with this splendid DIY sauna plan that comes with a hot tub that provides the ultimate comfort. Once you get in, rest easy that you never want to leave.
4. Finnish Sauna

5. DIY Near-Infrared Sauna
Recently, I have been obsessed with the idea of building an infrared sauna as soon as I read about their enormous benefits. It helps you lose weight, improves circulation, and regulates your sleep pattern – what’s not to love?

6. DIY Near-Infrared Sauna For Less Than $100
Contrary to popular opinion, a near-infrared sauna won’t cost you a fortune. You will only need about $100 to relax away from all the stress of your busy work week, which is reasonable considering the health benefits you derive.
7. DIY Near-Infrared Sauna Under $150
The near-infrared sauna sensation continues with another budget-friendly idea. However, don’t equate low prices with health risks. Models from RubyLux or TheraBulb are not only inexpensive but also protect you from harmful electromagnetic fields.

8. Cordwood Masonry Sauna
Cordwood construction gives you the best of both worlds: it’s aesthetically pleasing and conserves energy. Cedar is the top-notch choice for cordwood since it provides great insulation and is less likely to rot, but alternatives like oak or pine are also excellent.
9. Wood-Burning Sauna
It’s always a bummer to wake up seeing the heavy snow everywhere. Lucky for you, the wood-burning sauna in the backyard is set to give you some comfort with the great smell of pine wood. All it takes is 20 minutes to fight off the winter blues.

10. Dry Sauna
You’re missing out if you have never heard of or tried a dry sauna. Once you get out of it, your body is fully recharged and ready to get back on track again. Apart from that, it also makes your skin glow and boosts your mood.
Maximize your weekend getaway with this DIY dry sauna.
11. Wood-Burning Sauna Finished In 7 Days
It seems unbelievable, but you can build a wood-burning sauna from scratch in just a week. The finished product looks genuinely fantastic, and needless to say, that overhang porch has boosted the fixture’s curb appeal.

Creative DIY Sauna Plans Repurposed From Old Structures
The frustrating part about DIY is usually the budget limit, and this can’t get any truer when you are working on a sauna. Indeed, you don’t want to pinch your pennies by reducing the size – it will be a claustrophobic disaster, and cheap materials are a no-no.
Given that, it’s your best bet to make use of what you have already had. The choices are enormous, from an empty guest room that has been locked for years, a small shed that stores random stuff, or a closet that’s full of dust, waiting for a glamorous makeover.
12. The Indoor Bathroom Sauna
Transforming your bathroom into a sauna is feasible, and it is easier than you could have imagined. Like other saunas, this plan opts for cedar, the top-notch wood choice, as it does not expand much when hot. Infrared bulbs are installed in place of sauna heaters.
13. The Outhouse Sauna
This sauna used to be an outhouse, and it’s almost unrecognizable now. The hearth is constructed out of concrete blocks and houses the iron fireplace insert. Instead of running through the sidewall, the chimney in this plan goes straight through the roof.
14. A Sauna In The Shed
If you can transform the outhouse into a relaxing sauna, you can do the same thing with the old shed in your backyard. Declutter all your dusty stuff and turn it into a DIY project that is always occupied whenever the breezy wind arrives. Your guests will be amazed!

15. Trash Bag Sauna
Don’t be intimidated by the idea. This DIY sauna plan is an excellent way to let your kids have fun without costing you an arm and a leg. All you need is a long piece of log, some trash bags, a hot stone from the fire, and some small ones around the “sauna.”
16. Basement Sauna
Got a basement that has just been emptied? Why don’t you turn it into a sauna since you already have two walls in place? It saves plenty of your time, which means that you only need to install the pipes, the walls, and the heater.

17. The Closet Sauna
Surprisingly, installing a sauna is even more straightforward than a shower (yes, no joke) since no plumbing is involved. Moreover, you’ll be glad to know that a sauna does not rely much on space – it can be just as small as a walk-in closet.
18. DIY Room Turned Sauna
It’s incredible how the space has changed from dull and uninteresting to a relaxing retreat within just a few days. With the clear instructions provided, you will be able to pull off the project with no problems, I’m optimistic.

19. Sauna In The Bathtub
This “disposable” sauna idea costs next to nothing, and it’s shockingly easy to carry out. All you need to do is take advantage of your bathroom, preferably a small one, to generate more heat and fill the tub with warm water. Step in, relax, and reset!
20. Old Barn Finnish Sauna
With this DIY sauna converted from an old barn, you can kick back and relax like the Finnish do – grab a towel, sit on the bench, and let the steam perform a miracle on your skin. You will walk out feeling more refreshed than ever!
Sauna Kits That Are Quick And Easy To Install
I have to admit, building a sauna from scratch is not an easy task. Various factors need to be considered before you get down to work, such as the material and the safety measures, and the woodwork will be such a torment if you are new to the crafting game.
Lucky for you, there are various DIY sauna kits available on the market nowadays. They are pre-built, come with a multitude of accessories, and offer numerous design and color choices so that you can pick what matches your lovey-dovey home.
21. 4×5 Outdoor Sauna Kit
Sure, DIY is fun, but sometimes it can be quite challenging and calls for considerable effort. Given that, this sauna kit is perfect for you. Half the job has already been done, so all you have to do is assemble all the parts and customize the roof with your favorite color.

22. 4×6 Indoor Sauna Kit
This sauna kit is similar to the previous one regarding the dimension, but it’s designed for indoor use if you are concerned about your privacy. It can accommodate three people at once and easily fit in any corner of your house.
23. 5×6 Outdoor Sauna Kit
The 5×6 kit is the better option if you have plenty of space. Similar to the 4×5 one, the assembly is straightforward, and the kit comes with many accessories to elevate your sauna experience: a bucket, a wooden ladle, and a eucalyptus fragrance, to name a few.
24. 6×8 Outdoor Sauna Kit
If your family or friends are as passionate about saunaing and its advantages as you are, don’t hesitate to get this DIY kit, which fits more than four people at a time. It is made of premium Western red cedar, so you know it deserves a spot in your garden.

25. Outdoor Barrel Sauna Kit
Simple and versatile in design, a barrel sauna is an excellent option that brings a rustic touch to your backyard. The circular structure also provides more steam circulation than its rectangular counterpart, ensuring that your mind and soul are free from stress and worries.
