Recovery, Reimagined: How SWTHZ Built Its Sauna Experience on Clearlight

A fast-growing wellness franchise standardizes on Clearlight Full Spectrum Professional Sanctuary™ saunas to deliver a premium, repeatable infrared experience across every studio.

At a Glance

Partner: SWTHZ, a membership-based infrared sauna and contrast therapy studio franchise.

Clearlight products in use: Full Spectrum Sanctuary™ Professional 3-Person and Full Spectrum Professional Sanctuary™ 5-Person saunas.

Focus: Delivering a consistent, full-spectrum infrared experience as the anchor of a private recovery suite, at scale, across a growing studio footprint.

The Company

SWTHZ has built its reputation on a simple promise: make high-end recovery feel personal, private, and effortless. Each studio is designed

 around individual suites where members move through a guided routine on their own schedule, without the crowds or compromises of a traditional gym or spa. As the brand has scaled, that promise has raised the bar on every piece of equipment that goes into a suite, none more important than the infrared sauna at its heart.

The Challenge

Growing a premium wellness concept across many locations creates a hard problem: how do you guarantee that the experience in your newest studio feels exactly as good as your flagship? For SWTHZ, the sauna is where members spend the core of their visit, so any inconsistency in heat, comfort, or build quality is felt immediately. The team needed an infrared sauna partner that could deliver three things at once. SWTHZ needed a genuinely best-in-class therapeutic experience, a refined look that fit the aesthetic, and the reliability and supply to outfit suite after suite without sacrificing standards.

Why Clearlight

SWTHZ selected Clearlight’s Full Spectrum Sanctuary™ line as the foundation of its sauna experience. The full-spectrum heaters, delivering near, mid, and far infrared, gave members a complete, deeply warming session rather than a one-dimensional one, which matched the elevated standard SWTHZ wanted to be known for.

Just as important, the Sanctuary line gave SWTHZ room to design around different suite layouts and group sizes. The team standardized on two models: the Full Spectrum Sanctuary™ 3-Person for its core private suites, which allows for maximum relaxation for an individual and a guest if they choose to share their session, and the Full Spectrum Sanctuary™ 5-Person where social sessions or more room for stretching made sense. Using a single product family across both formats kept the look, feel, and quality of the sauna identical from one suite, and one studio, to the next.

Notably, SWTHZ chose to let the saunas stand on their own, without bolt-on add-on therapies. The full-spectrum experience itself is the draw, and keeping it clean and uncluttered reflects the brand’s belief that a great sauna doesn’t need gimmicks to deliver results.

“When SWTHZ set out to build the best recovery experience in the country, the infrared sauna couldn’t be an afterthought — it had to be the centerpiece. Clearlight gave us a sauna we could stand behind in every single suite, in every single market.”

— Nico Varano, CEO, SWTHZ

The Experience

Inside a SWTHZ suite, the Sanctuary sauna does the heavy lifting. Members step into consistent, enveloping full-spectrum heat the moment they sit down, with the kind of finish and craftsmanship that signals they’re somewhere premium. Because the 3-Person and 5-Person models share the same heating technology and build standards, the experience scales gracefully,  a solo member and a small group get the same quality of session, just sized to fit.

That consistency is what turns a first visit into a routine. When members know exactly what they’re going to get every time they walk in, the sauna becomes a habit rather than a novelty,  and habits are what a membership model is built on.

The Partnership

SWTHZ and Clearlight have built a working relationship grounded in shared standards. As SWTHZ continues to open new studios, having a sauna partner whose product line, quality, and support it trusts removes one of the biggest variables in opening a new location. The sauna is a constant, which lets the SWTHZ team focus its energy on members and service.

Looking Ahead

As SWTHZ expands, Clearlight’s Full Spectrum Sanctuary™ saunas remain the anchor of the in-suite experience. The brands’ alignment, which are premium quality, real therapeutic value, and a no-shortcuts philosophy, sets up a partnership built to grow studio by studio, market by market.
