Who should buy which
Buyers who want premium cedar and 316-stainless build quality at sub-$8K — and who specifically want a seated vertical-hybrid that keeps them neck-deep without floating or full-supine immersion.
You need delivery in under 4 months, you want the longest warranty in the category (Renu's 60-month tub wins), or you want a 2-person tub.
Buyers who want the safest single-purchase cold plunge — plug-and-play, large service network, and category-leading installed base.
You want sub-39°F temperatures, a 2-person tub, or premium cedar/metal aesthetics — see Renu Therapy or Morozko Forge.
