Who should buy which

Pick the Float Lab Custom if

Estate-grade wellness installations, family-office facilities, high-end private spas integrating float into a broader wellness room.

Skip if

You want a faster install (Dreampod ships in weeks, Float Lab takes months), or you don't need architectural-grade integration.

Pick the Sunlighten Signature Series if

Buyers who want a credible heritage-brand far-infrared sauna with lifetime heater warranty and the largest service network in the category - 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 220V access for 2-person+ cabins, or you can't justify $4K+ over a sauna blanket.
