Pick the HigherDOSE Full Spectrum Infrared Sauna, 2 Person (SKU HD-CUSTOM-2P) and 3 Person (SKU HD-CUSTOM-3P) if

Buyers who want a 2 or 3 person infrared cabin with chromotherapy lights and Bluetooth audio at a listed price they can order directly, who already have or can add the dedicated circuit it needs, and who will hire their own installer.

Skip if

You expect delivery into the room and assembly in the price; you want written warranty coverage before you pay, since HigherDOSE publishes its one line 5 year residential and 1 year commercial term; you may need to send it back after unboxing, since returns must be unopened; or you want a published EMF reading or an ETL, UL or CSA listing.

Pick the Sunlighten Signature Series if

Buyers who want a credible heritage-brand far-infrared sauna with a 7-year heater and cabinetry warranty, and who don't need near or mid infrared in the same cabin.

Skip if

You want full-spectrum (near + mid + far) in one cabin (move to mPulse), you live in an apartment without 240V access for the 4-person cabin, or you can't justify $5K+ over a sauna blanket.
