For many people committed to wellness and longevity, a sauna is more than a luxury, it is an investment in long-term health. The question is, are saunas HSA eligible and can they be purchased using a health savings account or a flexible spending account? Understanding how these tax advantaged accounts work, when a sauna purchase can qualify, and what documentation is required can lead to significant savings while providing profound health benefits. This complete guide explains the rules, the process, and how a Kyfe sauna can fit into your wellness and financial strategy.
Why HSA Eligibility Matters for Sauna Owners
A health savings account HSA or a flexible spending account is designed to help individuals and families pre tax pay for qualified medical expenses. These accounts allow you to set aside pre tax dollars through payroll deductions or direct contributions, which lowers taxable income and reduces the overall cost of eligible medical expenses. Employer contributions can add even more value, making these accounts a powerful payment option for those with a high deductible health plan or anyone looking to prepare for future medical costs. By using a health savings account for an eligible sauna purchase, you can align your wellness goals with smart financial planning.
The Short Answer, Saunas Are Not Automatically Eligible
By default, the IRS does not list saunas as eligible medical expenses. Saunas are considered wellness products, not medical devices, meaning they do not automatically fall under spending account qualified expenses. Whether it is a traditional sauna, infrared saunas, or a dry sauna, the purchase is not inherently a necessary medical expense in the eyes of the IRS. This means that saunas eligible for reimbursement through an HSA or FSA require additional documentation to demonstrate medical necessity.
The Path to Eligibility, Proving Medical Necessity
Saunas become eligible medical expenses when supported by a letter of medical necessity from a licensed healthcare provider. Medical necessity means the sauna purchase is prescribed to treat a specific medical condition such as chronic pain, arthritis, cardiovascular health issues, or post-injury recovery. The letter of medical necessity must explain how the sauna will address the medical condition, outline the expected health benefits, and detail the recommended sauna sessions for therapy. Without this, most HSA FSA administrators will reject the claim.
How to Get a Letter of Medical Necessity
Step 1: Consult Your Healthcare Provider
Start by meeting with your healthcare provider to discuss your medical condition and how sauna therapy might help. This can include goals such as pain relief, improved circulation, fatigue reduction, stress relief, improved cardiovascular health, or other physical health benefits. The provider must believe the sauna is necessary to address your condition, making it a necessary medical expense.
Step 2: Gather Documentation
The more documentation you have, the better. Medical records, test results, and details of your current year medical expenses help strengthen the case. This is especially important if your claim is reviewed in detail by your HSA or FSA administrator.
Step 3: Submit and Maintain Records
Submit your letter of medical necessity along with proof of sauna purchase to your HSA FSA administrator. Keep copies for your records in case the IRS requests verification. Because funds roll over in an HSA and may have a grace period ownership option in some FSA accounts, timing the claim can also maximize your benefit.
Sauna Types and Eligibility Considerations
Traditional Sauna
A traditional sauna uses high heat and, in many cases, steam to create an environment that promotes relaxation and cardiovascular health. When medically necessary, the deep heat therapy from a traditional sauna can support improved cardiovascular health, pain relief, and enhanced relaxation.
Infrared Saunas
Infrared saunas use infrared therapy or red light therapy to heat the body directly, which can result in increased collagen production, improved circulation, and reduced muscle soreness. For those sensitive to the high temperatures of a traditional sauna, infrared saunas offer a gentler but still effective form of heat therapy that may meet the medical necessity requirement.
Electric and Wood-Fired Saunas
While the heat source differs, both electric and wood-fired saunas can provide comparable physical health benefits when used consistently under medical guidance. Whether indoor electric or portable wood-fired, what matters is that the sauna sessions are part of a medically prescribed treatment plan.
Sauna Blankets and Portable Units
Even a sauna blanket may qualify under HSA FSA rules if prescribed and supported by a letter of medical necessity. This can be an appealing option for those with limited space but sufficient funds in their account to cover the cost.
Navigating HSA and FSA Administration
Each administrator has slightly different processes to determine eligibility. Some may require pre-approval, while others review claims after purchase. To save money and avoid delays, contact your HSA or FSA provider before making a sauna purchase. Explain that you have or will have a letter of medical necessity and ask about their preferred submission process. This proactive approach can ensure you meet all requirements for eligible medical expenses.
The Regulatory Landscape in 2025
In 2025, there has been discussion within the health insurance marketplace and legislative bodies about expanding eligible wellness products. While gym memberships and some wellness services may become more widely covered, saunas have not yet been explicitly included without documentation of medical necessity. For now, the safest approach is to follow the established LMN process for your HSA or FSA.

Frequently Asked Saunas and HSA/FSA Eligibility Questions
Do I need a prescription to buy a sauna with my HSA or FSA funds?
No prescription is needed to make the purchase, but a letter of medical necessity is required for reimbursement from your health savings account or flexible spending account.
Are portable saunas treated differently from built-in units for HSA or FSA purposes?
No. The key is medical necessity, not whether the unit is portable or fixed. Both can qualify if prescribed.
Can I use my FSA funds generally for sauna accessories?
Only if the accessory is considered part of the treatment for your medical condition and is included in your letter of medical necessity.
What if my claim is denied?
You can appeal, providing additional documentation or clarification from your healthcare provider to determine eligibility.
Are saunas eligible if they are primarily for relaxation?
Not without medical documentation. While saunas offer stress relief and mental and physical health benefits, general wellness use does not qualify as an eligible medical expense.
