Saltwater vs Chlorine Hot Tub: Which One Should You Buy?

Saltwater vs Chlorine Hot Tub at a glance

What the listings do not settle

These sides are not like-for-like substitutes. The saltwater listings are inflatable tubs, while the chlorine listings are granules for a tub you already have, so a buyer comparing them is choosing between a tub route and a care product, not between two tubs.

Both tub listings state the same 77 x 77 x 28 inch dimensions, yet one is listed as 4-Person and the other as 6-Person, so the listings leave how the person counts differ unclear. The 4-Person listing states saltwater system compatibility with the cell not included, while the 6-Person listing states saltwater system readiness without stating a cell as included, so neither tub listing states a cell as included.

No tub listing states heater wattage or a plug type, and no listing here states a safety certification, so power and certification checks stay with the listing, not with this comparison.

Gear for each route

These picks are scored on the Chill Score, which weighs performance, build and value, with safety where a certification applies, and warranty where a term is stated. No listing here states a safety certification, so no safety points are given, and warranty points follow a stated term in the 6-Person listing.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.

Choose the saltwater side if

• You want an inflatable tub listed as saltwater system ready or compatible.
• You want a tub with an energy-efficient spa cover stated.
• You want app control or a built-in hard water treatment system, as listed on the tubs here.

Choose the chlorine side if

• You already have a tub and want granules for routine care.
• You want a quick-dissolving dichlor formula to measure and add while water circulates.
• You want a 5 lb or 1 lb size, as listed.

Check Your Space First

• Allow floor space for a tub listed at 77 x 77 inches, with a height of 28 inches.
• Check the listing for heater power and plug type, since neither tub listing states them.
• Note the energy-efficient spa cover stated for both tub listings when planning where the tub will sit.
• Plan around granule packs listed at 5.0 pounds and 1.0 pounds, and note that tub weight is left unclear for the 4-Person listing and not stated for the 6-Person listing.

Common questions

Do the saltwater tubs include a saltwater cell?

No cell is stated as included. The 4-Person listing states compatibility with the cell not included, and the 6-Person listing states readiness without stating a cell as included.

Are the chlorine picks hot tubs?

No, they are granules for routine hot tub care. The listings describe measuring the granules and adding them while water circulates, for a tub you already have.

Why do the two tubs list the same size but different person counts?

Both tub listings state 77 x 77 x 28 inches, yet one is listed as 4-Person and the other as 6-Person. The listings leave how the person counts differ unclear, so treat the person count as a listing label, not a dimension.

Do both tubs include a cover?

Yes, both tub listings state an energy-efficient spa cover. The listings state high-density thermal-resistant foam that minimizes heat loss, with energy efficiency improved by as much as 50%.

Which side is for routine water care?

The chlorine granules are listed for routine care, with steady available chlorine when used as directed. The tub listings state cover, heater and construction features, without stating a sanitizer routine.
