From mirrored outdoor saunas to smart steam showers, sculptural and tech-forward fixtures are redefining how we treat ourselves at home—and how home feels.

A proper steam or sauna has long meant leaving the house to find one at a spa, gym, or hotel with a day rate. That’s quickly changing, and at-home wellness is more than a trend—the global sauna market is expected to grow from $950 million in 2025 to more than $1.5 billion by 2033, with private homes making up the biggest share of this growth.
For many design-conscious homeowners, steam showers and backyard saunas are now just as desirable as chef’s kitchens, pools, and outdoor entertaining spaces. And, when it comes to at-home wellness, few companies have been shaping the category for as long as Thermasol.
The company introduced the first residential electric steam shower in 1958, and has spent the 68 years since proving that wellness belongs at home. Now owned by Finnish sauna pioneer Harvia, which acquired it in 2024, Thermasol is continuing to elevate and revolutionize the way we experience wellness at home.

"We’ve officially outgrown the era where a home wellness space meant cramming a stationary bike into a spare bedroom and calling it a day," says Nathan Hagemeier, president of Harvia. "Today’s homeowners are demanding intentional, architecturally stunning sanctuaries built directly into the floor plan. We are no longer designing houses just to shelter people; we are designing them to actively restore them, turning ancient thermal rituals into the ultimate modern domestic luxury."

The Thermasol Vue sauna epitomizes this approach. Unrecognizable from the typical cedar box in the corner of the garden, Vue—which has been awarded a Luxe RED Award for its design—features panoramic glass walls framed in black enamel and thermally treated wood. The glass reflects its surroundings, allowing it to dissolve into the landscape while offering privacy to those inside.
