Which Tundra specs does this guide cover?
The specs on this page are for the Tundra shown in Arctic Spas’ May 2026 brochure. Arctic Spas has used the Tundra name for more than one model year, so an older tub may have different dimensions, water capacity, seating, or equipment. Check the serial plate and the manual that came with your spa before ordering a cover, pump, heater, or other year-specific part.
Tundra seating and layout
The Tundra has 7 molded seats and room for up to 7 people. It does not have a full-length lounger. This is a seven-seat open-footwell model combining four shuttle seats with three multi-level upright seats and no lounger.
If you are comparing models, pay attention to the footwell and lounger setup as much as the advertised capacity. A tub may technically hold the listed number of people but still feel tight once everyone is in it.
Jets and pump packages
Depending on the package and model year, the Tundra was offered with 60, 40, or 20 jets and up to 4 pumps. Check the equipment label inside your cabinet before ordering a pump, heater, control panel, or electrical part.
Why the package matters: Prestige uses one pump; Signature two; Legend and Legend Select three. Optional SDS can add a pump. The four-pump build, not the jet count by itself, triggers the 60A breaker requirement.
Electrical requirements for the Tundra
| 240V wiring method | 240V fixed wiring from the GFCI spa panel: Line 1, Line 2, neutral, and equipment ground |
|---|---|
| Published feeder-wire guidance | 6-gauge wire is listed in the 2026 Arctic Spas table; the manual does not specify one universal insulation type, conductor material, or raceway |
| GFCI breaker | 1 pump: 40A GFCI; 2 or 3 pumps: 50A GFCI; 4 pumps: 60A GFCI |
| Published equipment input | 1 pump: 32A actual; 2 or 3 pumps: 40A actual; 4 pumps: 48A actual |
| Heater | 5,500W on 240V; certified 115V variant uses 1,000W |
| Plug N Play | Not shown as a current Plug N Play upgrade in the May 2026 brochure |
| Plug-in electrical details | The 2026 manual contains a generic one-pump 115V line at 12A actual, 15A breaker, and 14-gauge wire, but the current brochure does not market Plug N Play for this model. Confirm factory availability before treating it as plug-in. |
| Spa disconnect | At least 5 ft (1.5 m) from the water, readily accessible, and within sight; within sight is generally no more than 50 ft under NEC terminology |
| Bonding conductor | At least No. 8 AWG solid copper to the local bonding grid in the United States, as required by the Arctic Spas manual and local code |
Breaker box and disconnect location: Arctic Spas says the GFCI disconnect must be readily accessible and visible to the hot tub occupant, but at least 5 ft (1.5 m) from the water. Under common NEC terminology, within sight generally means visible and within 50 ft, but the adopted code edition, amendments, product listing, and local inspector control the exact placement. The enclosure installed near the spa is commonly called the spa disconnect, GFCI spa panel, or spa subpanel.
Wiring and bonding: Arctic Spas requires a licensed electrician and local inspection. The certification label beside the controller determines the final voltage, actual load, breaker, and approved configuration. Where Arctic publishes a feeder gauge, it is shown in the model table; conductor insulation, terminal material rating, raceway, run-length adjustments, and local requirements still belong to the electrician. The manual calls for the spa bonding lug to connect to the local bonding grid with at least No. 8 AWG solid copper in the United States or No. 6 AWG stranded copper in Canada. Nearby metal equipment, enclosures, water pipe, conduit, and metal surfaces within 5 ft may also require bonding.
Plug-in configurations: The 2026 manual contains a generic one-pump 115V line at 12A actual, 15A breaker, and 14-gauge wire, but the current brochure does not market Plug N Play for this model. Confirm factory availability before treating it as plug-in. The manufacturer’s 5 ft appliance warning is not a complete receptacle-placement rule. Receptacle spacing, GFCI protection, cord length, and Plug N Play placement depend on the product listing and the NEC/CEC edition adopted locally.
Other electrical safety: The North American supply must include a suitable GFCI breaker that opens all ungrounded conductors. The load neutral must connect directly to the GFCI as shown in Arctic Spas’ licensed-electrician diagram. Never bypass the GFCI. The manual says no electrical appliance such as a light, phone, radio, or television may be within 5 ft (1.5 m) of the hot tub. Accessible controls or devices must meet the manual’s low-voltage and local-code requirements.
Will the Spa Filter Adapter fit the Tundra?
Our Spa Filter Adapter Kit v3 may fit a Tundra, but only when the tub is a 2020 or newer Custom Series with the matching Pro Filter and skimmer setup. The model name alone is not enough because Arctic Spas has reused several model names over the years. Before ordering, compare your filter area with the photos and checklist in our compatibility guide.
For any replacement filter, compare the cartridge height and diameter, the top and bottom openings, the thread style, and the space inside the filter housing. Those details matter more than the name printed on the side of the tub.

Arctic Spa Tundra FAQs
Is the Tundra a current Arctic Spa model?
Yes. The Tundra is included in Arctic Spas' May 2026 hot tub brochure.
What are the Tundra dimensions?
The Tundra measures 93 × 93 × 39 in (235 × 235 × 98 cm). Before ordering a cover or building around the spa, measure your actual cabinet and check the model year on the serial plate.
How much water does the Tundra hold?
Arctic Spas lists the Tundra at 411 US gal (1,556 L). Older versions may hold a different amount, so use the manual for your year when adding water-care chemicals.
How much does the Tundra weigh?
The listed dry weight is 951 lb (431 kg), and the listed filled weight is 4,381 lb (1,987 kg). People, steps, accessories, and snow add more load, so have a qualified professional check any deck or raised platform.
How many people fit in the Tundra?
The Tundra is listed for up to 7 people, with 7 molded seats. It does not have a full-length lounger.
Where can I find the Tundra manual or PDF?
Use the Arctic Spas links in the Manuals and drawings section above. Choose the document that matches your model year; a current brochure will not cover every part used in an older tub.
What electrical service does the Tundra need?
The published 240V installation is 240V fixed wiring from the GFCI spa panel: Line 1, Line 2, neutral, and equipment ground. Breaker guidance: 1 pump: 40A GFCI; 2 or 3 pumps: 50A GFCI; 4 pumps: 60A GFCI. Published wire guidance: 6-gauge wire is listed in the 2026 Arctic Spas table; the manual does not specify one universal insulation type, conductor material, or raceway. Not shown as a current Plug N Play upgrade in the May 2026 brochure. The certification label beside the controller is the final authority, and Arctic Spas requires a licensed electrician to follow local code.
Does the Spa Filter Adapter Kit v3 fit the Tundra?
It may, if your spa is a matching 2020 or newer Custom Series model with the correct Pro Filter and skimmer setup. Check the filter area and model year before ordering.
