Cold Plunge Chiller Comparison: What I Learned Building My Own Setup

Bought a generic rotomolded tub shell rather than a full branded kit, then sourced the chiller separately after comparing three different unbranded chiller units on cooling capacity and noise level. Ended up paying more for the quieter option, which I don't regret since the tub sits right outside my bedroom window.

Biggest lesson: check the chiller's rated capacity against your actual tub volume before buying — undersized chillers run constantly and wear out faster.
