Best Hot Springs Spa Models: Compatible Replacement Parts Guide
Hot Spring spa parts are model- and year-specific, so check your spa’s model name, production year, and existing part number before ordering. The products below are replacement parts rather than complete spa models: Bonbo’s pillow set is best for select 2014–2022 Highlife spas, IWIWE’s four-pack is for listed Hot Spot models, and the 74317 pillow fits certain 2007–2013 spas. A heater and filter are included for owners matching those part numbers.

Bonbo 77228 Highlife Pillow Set
This two-pack of gray replacement pillows is best for owners of the listed Hot Spring Highlife Collection models from 2014 onward. The compatibility list includes Aria, Envoy, Sovereign, Grandee, Prodigy, Jetsetter, Triumph, and Vanguard variants, with year ranges that differ by model.
The 77228 design is described as supporting the neck’s natural curve. Installation involves aligning the pillow and sliding its ends onto the spa retainer, without complicated tools. It was selected for its broad but specifically stated model coverage and straightforward fitting method.
Limitation: The listed compatibility does not cover every Hot Spring spa. Confirm the model and year against the product’s compatibility list before ordering.
IWIWE 77444 Hot Spot Pillow Four-Pack
This four-pack is best for owners whose spa uses the 77444 pillow. The listed fit covers Hot Spot Relay, Rhythm, Tempo, TX, and SX models across stated year ranges from 2011 through 2019. The seller describes the pillows as replacements made from high-density EVA foam with 45D firmness.
The product was selected for buyers needing multiple headrests and for its model-specific compatibility information. Its EVA material is described as wear-resistant and less prone to flaking, blistering, or disintegration than traditional materials.
Limitation: The supplied compatibility years and model names should be checked against the spa’s actual pillow part number; the listing does not establish fit for all Hot Spring spas.
XQK 74317 Cool Gray Spa Pillow
The XQK single pillow is best for owners who have confirmed that their mid-year 2007–2013 Hot Spring spa takes part 74317. It is a direct choice when replacing one pillow rather than buying a multi-piece set. The listing describes the pillow as soft and made for comfort during spa use.
This option was selected because it clearly identifies the part number and a defined year range. Compare the existing pillow or spa parts information with 74317 before choosing it.
Limitation: The listing says the pillow is not backwards compatible with older Hot Spring spas. Do not assume it fits a spa made before the stated period.
Camoo 6 kW No-Fault Heater
This replacement heater is best for owners whose existing unit matches 26-C3160-1S, C3160-1S, or 73790. The listing describes it as a 6.0 kW, double-barrel low-flow titanium heater with sensors and states suitability for listed Watkins, Hot Spring, Tiger River, and Limelight spas from 1995–2026.
It was selected because the product information gives cross-reference numbers that can help narrow down a replacement. The listing also provides wire-color information, but electrical work should be handled with appropriate care and expertise.
Limitation: Broad brand and year claims are not enough to verify a match. Confirm the number on the existing heater’s data label before ordering.
POOLPURE C-8465 Spa Filter
This filter is best for owners replacing a compatible 65-square-foot filter identified as Watkins 31114 or another listed cross-reference, including PWK65, Unicel C-8465, and Filbur FC-3960. Its stated dimensions are 10.5 inches long and 8.5 inches in outside diameter, with 3-inch openings.
The C-8465 was selected because its measurements and cross-reference numbers give buyers practical ways to compare it with the installed filter. The listing identifies it as a compatible replacement from an independent brand.
Limitation: Do not select a filter based on spa brand alone. Verify both the part number and physical dimensions.
Buying Guide: How to Match a Part to Your Hot Spring Spa
What information should you check first?
Find the spa’s model name and year, then inspect the existing component for a part number. For pillows, compare the shape, retainer arrangement, and listed model-year range. For heaters and filters, use the number printed on the old part and compare it with the replacement’s cross-references.
Are Hot Spring and Hot Spot parts interchangeable?
Not automatically. The products above list different model families and part numbers. A pillow specified for selected Highlife models should not be presumed to fit a Hot Spot model, and a brand-level match alone does not confirm compatibility.
How should you compare filters?
Check the filter’s part number, length, outside diameter, opening size, and filtration area. Match all available measurements to the installed filter. Replacement filters can share a brand application while differing in dimensions.
What should you verify for a heater?
Compare the existing heater’s data-label number with the replacement’s listed cross-reference. Because the heater is an electrical component, use the manufacturer’s guidance or a qualified spa professional if installation requirements are unclear.
Frequently Asked Questions
How do I find my Hot Spring spa model?
Check the spa’s identification label or owner documentation for its model name and year. Use those details when comparing a part’s compatibility list.
Can I choose a replacement pillow by appearance?
Appearance alone is not reliable. Confirm the pillow part number or the exact spa model and year because similar-looking pillows may use different retainers.
Does the 74317 pillow fit older Hot Spring spas?
The XQK listing states that it fits mid-year 2007–2013 models and is not backwards compatible with older spas.
Is the C-8465 filter an original Watkins part?
No. The listing identifies POOLPURE as an independent brand offering a compatible replacement and gives Watkins 31114 as a cross-reference.
