Quick answer: the current Arctic Spas Custom Series hot tub lineup includes Summit XL, Summit, Tundra, Kodiak, Klondiker, Yukon, Cub, and Arctic Fox. The official Custom Series manual also lists Frontier, which is best treated as a legacy/manual-reference model. Ocean and Okanagan are All-Weather Pool models, not current Custom Series hot tubs.
Use this guide to compare Arctic Spas Custom Series hot tub dimensions, heights, water capacity, dry weight, electrical requirements, and model-group notes before ordering filters, checking adapter fit, planning delivery, or confirming what model you actually own.

Current Arctic Spas Custom Series models
Arctic Spas currently lists these eight models under the Custom Series hot tub lineup. This is the core list most 2020+ Custom Series owners should use when comparing hot tub specs.
Arctic Spas Custom Series specs chart
The chart below keeps the current Custom Series hot tubs together instead of mixing them with All-Weather Pool models. Dimensions, capacities, and weights can vary by year, options, pump package, and regional electrical configuration, so use this as an owner-reference chart and confirm final details with your spa documentation when needed.
| Custom Series model | Outside dimensions | Height | Water capacity | Dry weight | North America electrical notes |
|---|---|---|---|---|---|
| Summit XL | 117″ x 93″ (297 x 235 cm) | 39″ (98 cm) | 537 gal (2033 L) | 1057 lb (479 kg) | 240V / 50A 4 pumps = 60A |
| Summit | 93″ x 93″ (235 x 235 cm) | 39″ (98 cm) | 360 gal (1363 L) | 935 lb (424 kg) | 240V / 50A 4 pumps = 60A |
| Tundra | 93″ x 93″ (235 x 235 cm) | 39″ (98 cm) | 411 gal (1556 L) | 951 lb (431 kg) | 240V / 50A 4 pumps = 60A |
| Kodiak | 93″ x 93″ (235 x 235 cm) | 39″ (98 cm) | 342 gal (1295 L) | 973 lb (441 kg) | 240V / 50A 4 pumps = 60A |
| Klondiker | 93″ x 93″ (235 x 235 cm) | 39″ (98 cm) | 373 gal (1412 L) | 944 lb (428 kg) | 240V / 50A 4 pumps = 60A |
| Yukon | 85″ x 85″ (217 x 217 cm) | 41″ (104 cm) | 334 gal (1264 L) | 735 lb (333 kg) | 240V / 50A |
| Cub | 85″ x 85″ (217 x 217 cm) | 41″ (104 cm) | 275 gal (1041 L) | 741 lb (336 kg) | 240V / 50A |

Legacy Custom Series reference: Frontier
Frontier appears in the official Arctic Spas Custom Series manual specifications, but it is not shown in the current public Custom Series hot tub lineup. If you own a Frontier, treat it as a legacy/manual-reference Custom Series model and double-check your exact year and filter setup before assuming any current accessory or filter guidance applies.
| Legacy/manual model | Outside dimensions | Height | Water capacity | Dry weight | Electrical notes |
|---|---|---|---|---|---|
| Frontier | 93″ x 85″ (235 x 217 cm) | 39″ (98 cm) | 335 gal (1268 L) | 785 lb (356 kg) | 240V / 50A |
Ocean and Okanagan are All-Weather Pool models, not current Custom Series hot tubs
Older owner notes and dealer material can make Arctic Spas model lists messy. Ocean and Okanagan are All-Weather Pool / swim-spa style models, not current Custom Series hot tubs. They are separated here because owners often search them alongside Custom Series specs, but they should not be used to define the current Custom Series hot tub lineup.
| All-Weather Pool model | Outside dimensions | Height | Water capacity | Dry weight | Notes |
|---|---|---|---|---|---|
| Ocean | 172″ x 93″ (436 x 236 cm) | 51″ (129 cm) | 1347 gal (5100 L) | 1910 lb (866 kg) | All-Weather Pool / swim-spa reference |
| Okanagan | 172″ x 93″ (436 x 236 cm) | 51″ (129 cm) | 1347 gal (5100 L) | 1910 lb (866 kg) | All-Weather Pool / swim-spa reference |
Which Custom Series models are the same size?

- 93″ x 93″: Summit, Tundra, Kodiak, and Klondiker.
- 85″ x 85″: Yukon and Cub.

Are the supported Custom Series models compatible with Kit v3?
Yes. The supported 2020+ Arctic Spas Custom Series models shown on the Kit v3 product page are confirmed compatible. The filter-cover photo is a backup check when the model year or setup is uncertain, not a second requirement for a confirmed supported model.
If you are unsure about the model year or setup, compare the top of the original filter covers in the Arctic Spa filter adapter compatibility guide. Otherwise, order Spa Filter Adapter Kit v3 for a supported 2020+ model.
