Nothing like a good schwitz to get through cold and flu season, right? Or really, anytime of the year if you’re Scandinavian or Japanese or Icelandic, or … Hey, we are missing out! We need a sauna. In a box. Such as the wood burning sauna box by Toronto-based design studio Castor, built right into an 8x8x8-foot reclaimed shipping container.

It’s conveniently self-sufficient with a wood-fired stove and solar panel. But wait, there’s more. It comes with – in perfect man cave fashion – an electric guitar hookup. In case you want to shred while dripping for your health. There’s also an awesome, hand-carved limestone stool, an iPod stereo, truck light and, oddly, bronze antlers. The interior is done in Western red cedar and red steel. Cost? $41,000.

Since it creates its own power, you can set the Sauna Box up wherever you desire: your off-the-grid plot of land, your suburban backyard, or your flat rooftop (weight considerations allowing). When not in use, you just lock it up, like any box.

This little beast is sold by Matter, a gallery, showroom and manufacturer in NYC devoted to not just scouting and selling stuff, but providing a “platform for an ongoing conversation about design by the design community and the public alike.”

We’d certainly like to have a conversation about the electric guitar!

“This traditional wood-burning sauna is built into a shipping container. The Sauna Box is completely self-contained with solar power and a wood-fired stove. The box comes standard with iPod stereo, guitar hook-up, Castor Stool, magnetic truck light, wool toque and bronze antlers. The Sauna Box can be customized to suit the site.”

Its work tests the limits of materials, both in terms of aesthetic and structural properties, blurring the line between the practicality of engineering and the indulgence of art.”

“Castor Design’s products involve thoughtful experimenting with process and techniques, finding new ways to use familiar materials. The Recycled Tube Light earned Castor their reputation for recontextualizing; the attention to narrative is maintained throughout their lines of lighting, furniture, and accessories.”
