Dynamic Sauna Assembly: Step-by-Step Guide from the Owner's Manual

A Dynamic infrared sauna is built from pre-wired panels that buckle together, so you don't need carpentry skills. You need two adults, a Phillips screwdriver and a ladder, a dry and level spot, and a dedicated 120V outlet (15A for 1 to 2 person models, 20A for 3 and 4 person models). The usual order is floor, front, side walls, rear wall, roof, bench heater and bench, then the roof plugs and roof cover.

This guide follows Dynamic's owner's manuals (checked November 2026). Panel order and a few parts vary by model, so keep the manual for your exact model open as you work.

Before you start

• Check the heaters first. The manuals ask you to look over every heater panel for transit damage before assembly. If one is damaged, don't switch the sauna on; ask for a replacement part.
• Find the manual and small parts. The owner's manual and the accessory box sit inside the roof panel, under the thin hardboard roof cover.
• Pick the spot. It must be dry, level and away from any water source, with the power cord able to reach the outlet easily. Our guide on where to place a sauna covers rooms, floors and clearance.
• Get the power right. The sauna plugs into a dedicated, non-GFCI 120V outlet: 15A for 2-person models, 20A for 3 and 4 person models. No extension cords, adapters or surge protectors. Use a certified electrician for any wiring work.
• Write down the serial number. It's on the front panel, rear panel or the shipping carton. You'll need it for warranty or parts.

Step-by-step assembly

This is the order in the Bergamo, Bellagio and Vittoria manual. Some models, such as the Barcelona, fit the bench heater and bench before the roof, so follow your own manual where it differs.

1. Floor panel. Set the floor panel in place, leaving room to work around it. The wood guide strips at its front and rear are where the front and rear walls sit.
   
2. Front wall with glass door. Stand the front panel on the floor panel, snug against the front guide strip.
   
3. Side walls. Lift each side wall so its metal brackets hook onto the front panel, then pull it down to lock. The top of the side wall should sit flush with the top of the front wall. Heater panels sit nearer the top of each wall, which tells you which way is up.
   
   
4. Rear wall. Peel the protective paper off the buckles, set the rear wall on the floor panel and latch it to both side walls. The rear wall is bowed on purpose for strength: one person pushes it outward from inside while the other closes the buckles, working from top to bottom.
   
5. Roof panel. The control box side faces up and the edge nearest it faces front. Feed every wire from the walls, and the control harness, through the roof holes as you lower it. Don't force it; it should sit snugly on the walls.
   
6. Bench heater and bench. Slide the bench heater panel down into the guides on the side walls and plug it in, along with the floor heater. Angle the bench in, slide it along the side guides to the rear wall, finished side up. If your model has LED lights under the bench, connect them first. Screwing the bench to the rear wall is optional.
   
7. Door handles. The glass door sits between two white washers; screw the outer handle on from inside, then fit the inner handle and tighten its hex screws. Don't over-tighten, or the glass can crack.
8. Roof plugs. Connect each plug on the roof to the one with the matching label: speakers, MP3 or aux, heaters and the control harness.
   
9. Temperature sensor. Inside the sauna, remove the protective tape from the sensor and turn it so it points straight down. Some models also have an optional shelf, towel rack or magazine rack to screw on now.
   
10. Roof cover. Feed the power cord through the hole in the roof cover, lay the cover on the roof panel and screw it down once the edges line up.
    

Tip: it's easier to fix a loose plug before the roof cover goes on, so many owners plug in and run a quick heat check first, then fit the cover.

Video: assembling a Dynamic sauna

Dynamic's manuals point to the maker's assembly video, "How to Assemble Your Dynamic Far Infrared Sauna" (shown with this post). It may not show your exact model, but the manuals say all their saunas go together in a similar way.

First switch-on and test

1. Peel the plastic film off the control panels.
2. Check that every connection is snug: power cord, heaters, radio and temperature sensor.
3. Plug straight into the dedicated wall outlet and press POWER. The display starts at 90 minutes and 151°F.
4. Set the time and temperature and press START. Expect about 20 to 30 minutes to warm to around 118°F; a cold room takes longer.
5. Check every heater panel is warming. The bench and floor heaters are lower wattage and only feel warm, not hot.

Most owners use 118°F to 122°F. The manuals suggest about 115°F for 20 to 30 minutes on your first few sessions, and our sauna safety guide covers session times. The sauna needs a one-hour rest after every three hours of continuous use.

Common assembly problems

For anything else, our Dynamic sauna troubleshooting guide goes through the manual's fixes one by one.

Care after assembly

• Cleaning: unplug the sauna, then wipe with plain water and a soft, damp cloth. The manuals rule out chemical cleaners because the wood can absorb them and release them when heated. More in our sauna cleaning guide.
• Towels: sit on a folded towel and never drape one over the floor heater.
• Power: unplug the sauna if you won't use it for a while.
• Keep it indoors: Dynamic's warranty covers indoor use only. Mail the warranty card with proof of purchase within 60 days.
