What is the typical corner radius on 89" x 89" Hot Tub Cover hot tubs?

Most 89" x 89" Hot Tub Cover models use a 4 to 10 inch corner radius depending on the series. Measure carefully using a straight edge against the corner to confirm before ordering.

How do I find my 89" x 89" Hot Tub Cover hot tub model?

Your 89" x 89" Hot Tub Cover model is usually printed on a sticker inside the equipment compartment, or molded into the shell underneath the headrests.

Do I need a custom cover or will a ready-to-ship cover fit my 89" x 89" Hot Tub Cover spa?

Ready-to-Ship covers fit common sizes (82 inch to 93 inch). If your 89" x 89" Hot Tub Cover spa falls outside these standard sizes or has a unique corner radius, a custom cover is the better choice. Our team confirms your specs with you before production starts.

89″ x 89″ Is a Mid-Large Spa Size

Measure outside-to-outside on the top edge of your spa shell to confirm. See our measurement guide for instructions.

Which hot tubs use an 89″ × 89″ cover?

According to their manufacturers’ current spec pages, these models measure 89″ × 89″ (7′5″ square):

Sundance: Optima and Cameo (880 series), Hamilton and Chelsee (780 series), McKinley (680 series)
Caldera: Geneva and Niagara (Utopia), Palatino (Vacanza), Salina (Paradise)
Hot Spring: Pulse (2025 and newer)*

*Hot Spring redesigned the Pulse around 2025 — earlier Pulse models measure roughly 84″ × 90″ and need a different cover, so measure first if yours is older.

Sizes above are the manufacturers’ current published footprints (rounded-feet labels like “7′ × 7′” are shown in inches). Model years vary and shells get redesigned, so before ordering: measure your shell outside-to-outside and check your corner radius against the option list — our measuring guide takes about 15 minutes. Not a match? Request a custom quote and someone from our team will confirm every spec in writing.
