Who should buy which
Mid-premium buyers who want chillered convenience, sub-Plunge temperatures, and don't need cedar aesthetics or a 5-year-old installed base.
You want the largest service network (Plunge), or you want premium aesthetics + 34°F (Renu).
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.
