*Product-price snapshot, not an installed-cost promise. “From,” sale, and bundle pricing can change. Working allowances intentionally include room for common project layers but cannot replace a site-specific quote.

Path 01 · Manual ice

Low machinery, high routine.

The economic question is not just tub price. Estimate ice cost, storage, lifting, temperature consistency, water changes, and whether the routine will still feel reasonable after the novelty wears off.

Water / filled weight: 77 gal / about 700 lb
Empty weight: 61 lb

Verify before buying

Ice volume, cost, storage, temperature measurement, cleaning, and water-change routine.
Support capacity and permission for any deck, balcony, or indoor installation.

Path 02 · Modular chiller

Replaceable components, visible connections.

External chillers make the system easier to stage and potentially easier to service, but require deliberate hose routing, equipment airflow, leak control, weather protection, and noise placement.

Compact modular$5,149.98 component subtotal

Path 03 · Integrated systems

Cleaner package, bigger service question.

Integrated systems can simplify the visual installation. Before paying the premium, identify which parts are field-replaceable, who performs warranty labor, and what happens if the chiller cannot be repaired locally.
