Sweat Kingdom · Buyer's Guide
Financing, monthly payments, and using your HSA/FSA, plus the real total cost and an honest answer on whether it's worth it.
You can pay in full, finance through Affirm, or, if you qualify, use HSA or FSA funds. Affirm offers monthly payments, including 0% APR for up to 24 months on approved credit. HSA or FSA funds may be an option through our Truemed partnership if a licensed provider finds a sauna medically appropriate for you, but that isn't guaranteed. Whichever you choose, budget for the full installed cost, not just the sauna: electrical, foundation, and assembly can add $500 to $5,000 or more.
A home sauna is a big purchase, and buyers ask the same questions before they commit: Can I pay monthly? Will my HSA cover it? Is it tax deductible? What will it really cost once it's installed? This guide answers each one honestly, including the parts that aren't a sales pitch.
Can You Finance a Sauna?
Yes. Many sauna companies offer financing, and Sweat Kingdom does too. On every sauna's product page, the Pay Monthly tab shows how financing through Affirm works for that model.
-
0% APR for up to 24 months on approved credit. See the plans you qualify for at checkout.
-
Checking your options won't affect your credit score. Affirm runs a soft credit check to show the plans you qualify for.
-
You see the total cost before you commit. Your monthly payment, interest rate, and total are shown upfront.
Some store credit cards advertise "no interest if paid in full" within a promo period. Miss the payoff date by a day and they can charge all the interest back to the date you bought. That's called deferred interest. Affirm loans work differently: they use simple interest, and the total you'll pay is set when you sign up. Whatever you use, read the terms before you buy.
Honest take: if you can pay cash without draining your emergency fund, that's the simplest way to buy. Financing makes sense when you'd rather keep cash on hand, or when 0% APR lets you spread the cost out without paying extra.
What Does a Sauna Cost Per Month?
Here are examples at two price points: about $6,000, near our lowest starting price, and $9,000, about the starting price of The Summit, our best-selling outdoor sauna. Your rate and terms depend on your credit and Affirm's approval.
| How You Pay | Monthly | Total Paid |
|---|---|---|
| $6,000 sauna, 0% APR for 24 months | $250 | $6,000 total. No interest. |
| $9,000 sauna, 0% APR for 24 months | $375 | $9,000 total. No interest. |
| Pay in full | — | The sauna's price, paid upfront. No interest. |
Examples only, not a quote or offer of credit. Sauna price and financing terms vary. See the Pay Monthly tab on any product page for current options.
If you don't qualify for 0% APR, Affirm shows your rate and total before you commit. Compare the total, not just the monthly payment.

Can You Use an HSA or FSA for a Sauna?
You may be able to, but it isn't automatic. A sauna isn't on the standard list of HSA/FSA-eligible expenses. It can qualify only when it's used to treat, manage, or prevent a specific medical condition, and that usually requires a Letter of Medical Necessity (LMN) from a licensed provider.
How Truemed works
Sweat Kingdom partners with Truemed, a service that connects you with a licensed provider. You'll find it on the HSA/FSA tab of each product page.
-
Choose Truemed at checkout. Select the HSA/FSA option through Truemed.
-
Answer a short health survey. A licensed provider reviews your answers.
-
Get a decision. If the provider finds a sauna medically appropriate for you, Truemed issues an LMN. If not, you won't get one.
-
Pay or get reimbursed. Pay with your HSA/FSA card, or pay another way and submit the LMN and receipt to your plan for reimbursement.
It's a fair question. In March 2024, the IRS warned consumers about companies claiming wellness products are HSA/FSA eligible with just a doctor's note. The rule is that a purchase has to be primarily for medical care of a specific condition, not general health.
So keep it simple: only use HSA/FSA funds if you have a real health reason, keep your LMN and receipt, and know that your plan administrator makes the final call. If you're unsure, talk to your plan administrator or a tax professional first.
FSA deadline: many FSAs are "use it or lose it," so unused money may be forfeited at the end of your plan year. Some plans offer a grace period or a limited carryover. HSA funds roll over every year, so there's no deadline.
Is a Home Sauna Tax Deductible?
Usually not. A sauna bought for personal use is a personal expense, so it isn't deductible for most people. There are a few narrow exceptions:
-
Medical expense deduction. If a sauna is medically necessary, part of the cost may count toward the medical expense deduction. You'd have to itemize, and only medical expenses above 7.5% of your adjusted gross income count. Because a permanent sauna can add value to your home, only the part of the cost above that added value may count.
-
Business use. A sauna used in a business, like a gym, spa, or short-term rental, may be deductible as a business expense.
-
No double-dipping. If you pay with HSA/FSA funds, you can't also deduct the same cost.
Tax rules depend on your situation, so check with a tax professional before you count on a deduction.
The Real Total Cost
The most common regret we hear from sauna buyers isn't the sauna. It's the costs they didn't plan for. Before you decide how to pay, add these to the sauna's price:
| Cost | Typical Range | What to Know |
|---|---|---|
| Electrical | $500 – $1,500 | Traditional saunas need a dedicated 240V circuit from a licensed electrician. A panel upgrade can add $1,500 or more. |
| Foundation | $0 – $3,000 | $0 indoors or on existing level concrete. Gravel is the budget outdoor option. |
| Assembly | $0 – $1,500 | $0 if you DIY with 2–3 people. Our assembly service is $1,500. |
| Running cost | ~$1/session | About $0.60–$1.60 in electricity per session, including preheat. |
Get your electrical quote before you order, since it's the cost that varies the most. For foundation options, see our sauna foundation guide. For a complete breakdown with real-world examples, see our home sauna cost guide.
Is a Home Sauna Worth It?
It's worth it if you'll actually use it. A sauna you use three or more times a week gets cheaper every session. One that sits unused is an expensive backyard decoration.
The other lesson buyers share often: buy once. A cheap imported sauna can look like a deal until the wood warps, the hardware rusts, or the heater can't keep up in winter, and then you're buying a second sauna. Paying more for a well-built sauna with a real warranty usually costs less over time.
The cheapest sauna is rarely the least expensive one. Buy the one you'll still be using in ten years.
Every Sweat Kingdom sauna is built in Idaho Falls from 100% natural cedar, with a 3-year warranty and a 30-day home trial (terms apply). Not sure which model fits? See our guide to choosing the best outdoor sauna for your home.
