The Tardis

My latest project came about because of the enthusiastic insistence of the client, who, with typical Finnish ingenuity, decided that her tiny “garden shed” needed to become a sweet little sauna. Typically, for the electric saunas I build, I carve out space in the recesses of a dark basement or some other unused corner of the house. This space had its own bright little shell for me to work with, perfectly placed a few paces from the kitchen door. The exterior had charm, so I left that alone except for the new galvanized metal roof, which mirrors its surroundings. It is clandestinely tucked into the yard, so that unbeknownst to the  neighbors, there is a whole world of warmth inside.

It immediately reminded me of a Tardis. For those of you not up on Dr. Who, of the popular British TV series, a Tardis is a time machine in the form of a phone booth. And Tardis is an acronym for Time and Relative Dimensions in Space. When the door is opened, an enormous interior is revealed. My challenge was to make this 64 sq. ft. shed completely functional as a sauna and feel larger than it is. So far it has surpassed my expectations. It feels roomy, airy, and comfortable for two or three people with a heat that burns deep and a löyly that lingers just long enough. I even fit in a foyer/disrobing area. Stepping out of it in a cloud of steam, it is hard to reconcile the size of the outside with the comfort of the interior.

Like the Tardis, the sauna is a time machine. Once inside, the heat takes you to another dimension as minutes turn to hours and worries melt away like the face on a Dali watch. Sometimes, I want to thank my clients more than they thank me, for the inspiration to create something so perfect and for taking me out of my world and into theirs.

The Light in the Sauna

My family name, Licht, came from my German ancestors who made candles—the family crest features a candle—so it’s no wonder that I think about lighting a lot.

The most important thing about building a sauna is creating the right atmosphere. It’s not just about temperature, it’s about engaging all of the senses in a soothing way. The sauna is a sweat bath, light therapy, aroma therapy, and talk therapy session all rolled into one.

With that in mind, I think hard about the quality of the light in the sauna room.

Although all sorts of colored LED and optic fiber lights are available, I try to avoid any electric lighting. In fact, if it is a traditional woodburning unit, I avoid electricity entirely. Not only is it not needed to run a woodburning sauna, but if there is an electric line to the building then there will be a temptation to add outlets and harsh outdoor lighting. The next thing you know, someone is plugging in some beeping device or the light is blotting out the night sky and the whole experience is compromised. What you want is dim light that will let your eyes adjust to the darkness and that will make even the most modest bather feel comfortable, even if their towel happens to slip off. A few candles can be just enough to light the sauna room. The problem with candles is that they will melt in the sauna—even if you don’t light them! To solve this, I install a candle window above the mantle so the candle (or lantern) stays in the dressing room and lights both rooms.

I also consider daylighting and place windows to allow for natural light without compromising a sense of privacy. When rough framing the windows, I leave space so that the window placement can be adjusted to frame the perfect view when seated on the bench (but not the perfect view from outside).

In an electric sauna, I will often put a light under the bench, with a dimmer, so that there is no harsh light, only a soft glow that sweeps across the floor. No one wants to stare at a glowing light fixture (which is exactly the situation in most commercial units). Whatever the situation, I work with the light to create just the right ambiance.
