Who should buy which
Budget-conscious buyers who want chillered convenience but can't justify $9K+ — accept some warranty downside for a 50% discount.
You want the longest warranty (Plunge or Renu), or maximum service-network depth.
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.
