An uncovered spa loses heat between soaks and collects leaves, dust and rain, so the cover matters as much as the tub itself. A good cover for an inflatable spa has to fit the round shape, stay put in wind, and keep debris out of the water. This guide compares the best hot tub cover for inflatable spa options on what each listing states, from insulated lids to waterproof shells, so the choice follows the spa shape and the weather it faces.

How to choose the best hot tub cover for inflatable spa
Fit comes first. Measure the spa before buying, as the Tlswshsy listing asks, and compare the result with the listed size of each cover, from 55 in by 55 in for the LFUTARI lid to 96 in by 96 in for the Puzau lid. Insulation is the next split: insulated covers state heat retention for cold weather, while the XCZ cover states clearly that it is waterproof and dustproof only. Wind fixing also matters outdoors, with anti-wind straps on the Tlswshsy cover and drawstrings on the XCZ cover. For the difference between insulated and non-insulated covers, see insulated vs non-insulated hot tub cover.
Size, material and fit
| Cover | Size | Material | Fit help |
|---|---|---|---|
| Tlswshsy Thermal Cover | 85 in by 27 in | Vinyl | Anti-wind straps, handles |
| Puzau Inflatable Cover | 96 in by 96 in | Vinyl | Double handles, storage bag |
| XCZ Oxford Spa Cover | 86.6 in by 86.6 in by 27.5 in | 600D heavy duty Oxford cloth | Two drawstrings, two handles, Velcro opening |

Who should not buy these
Buyers with a spa that is not round should skip all four covers here, since every listing describes a round cover. Buyers who need insulation should skip the XCZ cover, which states it is not insulating. Buyers whose spa is larger than the listed sizes should measure carefully and look elsewhere, since none of these listings states a larger size. For winter use, see hot tub cover for winter, and for shape choices, see round vs square hot tub cover.
Score notes
The Chill Score scores each cover on performance, build, value, safety and warranty, using only what each listing states. Safety is zero for all four covers here, since none states a certification, and warranty is zero for all four, since none states a warranty term.
| Product | Chill Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Tlswshsy Thermal Cover | 9.6 | 29 | 21 | 21 | n/a | 0 |
| Puzau Inflatable Cover | 9.6 | 28 | 20 | 20 | n/a | 0 |
| XCZ Oxford Spa Cover | 9.5 | 26 | 21 | 20 | n/a | 0 |
| LFUTARI Inflatable Lid | 9.5 | 26 | 19 | 19 | n/a | 0 |
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.
The Tlswshsy cover leads on insulation, with silk wadding and anti-wind straps. The Puzau lid follows with an inflatable thermal design, handles and a storage bag. The XCZ cover suits buyers who need waterproof protection without insulation, and the LFUTARI lid suits smaller round spas.
Check Your Space First
- Measure the spa before buying, as the Tlswshsy listing asks, and compare it with the listed cover size.
- Check that the spa is round, since all four covers here are described as round.
- Check storage space for a cover that folds away, as the Tlswshsy cover folds and the Puzau cover includes a storage bag.
- Check cleaning care, since the Tlswshsy, Puzau and XCZ covers are hand wash only, while the LFUTARI lid is cleaned with mild soap and water.
Common questions
Do inflatable spa covers keep heat in?
Insulated covers state heat retention: the Tlswshsy cover uses silk wadding, the Puzau cover uses flame-retardant material that locks in heat, and the LFUTARI lid states heat retention and sun heat absorption. The XCZ cover is different, since the listing states clearly that it is not an insulating cover, only a waterproof and dustproof cover.
How do I pick the right size?
Measure the spa first, then compare it with the listed sizes: 85 in by 27 in for the Tlswshsy cover, 96 in by 96 in for the Puzau lid, 86.6 in by 86.6 in by 27.5 in for the XCZ cover, and 55 in by 55 in for the LFUTARI lid. The Puzau listing also describes a 4-6ft range, so check both the range and the dimensions before buying.
Will a cover stay on in wind?
Wind fixing is stated for two covers: the Tlswshsy cover includes anti-wind straps, and the XCZ cover includes two drawstrings at the bottom. The Puzau listing states the cover withstands wind, rain and snow outdoors, while the LFUTARI listing describes a floating inflatable lid with no wind fixing stated.
Can a cover be folded away?
The Tlswshsy cover folds away when not in use, and the XCZ cover is listed as foldable. The Puzau cover includes a storage bag for storage after use. Folding is not stated for the LFUTARI lid, so buyers who need a folding cover should choose one of the other three.
What material should I expect?
The Tlswshsy and Puzau covers list Vinyl, the LFUTARI lid lists Polyvinyl Chloride (PVC), and the XCZ cover lists 600D heavy duty Oxford cloth. Material alone does not decide insulation: the XCZ cloth cover is waterproof and dustproof, while the Vinyl Tlswshsy and Puzau covers state heat retention.
