DELIVERY & INSTALLATION
UP IN AN AFTERNOON
01 | Lay the base
Place the floor panels on a flat, level surface. The interlocking system clicks together — no tools or fasteners at this stage. Takes about 10 minutes.
02 | Raise the walls
Slot each wall panel into the base channel. The precision locking system keeps panels plumb and square.
03 | Set the glass
Lift the double-insulated glass panels into the front frame. The panels are pre-gasketed — they seal against the frame .
04 | Add the roof
Lower the ceiling panel onto the top of the wall assembly. It locks into the same channel system as the walls. This fully encloses the unit and completes the insulated shell.
05 | Heater + ThermaRed
Hang the Harvia electric stove on the pre-wired wall bracket inside the unit. Connect the power lead to the stove's terminal. This is the only step that requires a licensed electrician.

A Note From Taylor,Designer & Co-Founder
Traditional doesn’t have to look traditional.
I designed VAULT around contrast—cold black metal against warm Thermopine Aspen, finished with a proprietary compressed quartz floor. Every material was chosen to make the sauna feel architectural, substantial, and completely different from the wood boxes we’ve come to expect.
VAULT is our interpretation of what a traditional sauna should look like today.

Sauna Frequently asked questions
What is ThermaRed™?
ThermaRed™ is LIT's red light panel, built into the Vault and engineered to run in full Finnish heat. It combines five wavelengths of red and near-infrared light (590, 630, 660, 830, and 850 nm), so you get a true sauna session and red light in the same sitting.
Which light mode should I use?
Recover is built for post-workout sessions, inflammation for everyday use, rejuvenation for skin, Energize for mornings, and Sleep for evenings. Each mode runs 20–30 minutes and turns off on its own.
Can I finance my sauna?
Yes! We offer 0% APR financing for up to 36 months. You can easily apply by proceeding to checkout and selecting our trusted financing partner, Bread Pay. The application process is quick, and only a soft credit check is required — meaning it won’t impact your credit score.
Can I use the Vault outdoors year-round?
Yes. The gunmetal exterior is engineered specifically for outdoor exposure including UV, rain, snow, and temperature swings. The double-insulated glass panels retain heat efficiently even in cold climates. If you're placing it outdoors in cold climates, you'll want to upgrade to the 8KW heater which can handle freezing temperatures as low as -30F.
How hot does it get, and how fast?
The Harvia Spirit 6kW heater reaches up to 200°F and heats the Vault in about 30 minutes, depending on the outdoor temperature.
What electrical do I need?
The heater needs a dedicated 240V, 30A circuit installed by a licensed electrician. It's the only part of the setup that needs a pro. ThermaRed is fully integrated into the unit.
How is it delivered, and how long does assembly take?
Your Vault arrives by scheduled freight delivery, and two people can assemble it in about 2-4 hours. Prefer help? Professional installation is available with our professional installer network.
Do I need an electrician to install the vault?
The one step that requires a licensed electrician is connecting the Harvia stove, which runs on a 240V dedicated circuit 30A. This is standard for any electric sauna or hot tub install. Budget roughly 200–500 for the electrical work depending on your local rates and whether a new circuit needs to be run.
Does it include built-in speakers?
Yes! The sauna comes equipped with fully integrated Bluetooth (BLE) speakers, so you can easily connect your device and enjoy your favorite music, podcasts, or meditation playlists during your session — no wires, no hassle.
What is the warranty?
Yes! The sauna comes equipped with fully integrated Bluetooth (BLE) speakers, so you can easily connect your device and enjoy your favorite music, podcasts, or meditation playlists during your session — no wires, no hassle.
