Quick Answer: The best AquaRest hot tub for most buyers is the DISCOVER Standard 150 (the spa long sold as the AR-150 Select) — a roto-molded, 120V plug-and-play spa with 12 jets and a 1.5HP pump for around $2,699, per AquaRest’s own pricing. The Premium 150 adds a stronger 2HP pump, an ozone system, and convertible 120V/230V power for about $2,829 at the same footprint. Need to seat six? The Premium 600 (the former AR-600) brings 29 jets and a 240-gallon shell for around $3,449. One thing to know before you shop: AquaRest sells the same spas under two different naming schemes depending on where you look.
AquaRest shows up constantly in plug-and-play hot tub searches, and its own rebrand hasn’t made that easier — the AR-150, AR-500, and AR-600 model numbers that Walmart, Wayfair, and Home Depot still use are the exact same spas AquaRest now sells directly as the DISCOVER Standard, Premium, and Elite tiers. This guide breaks down what each 2026 AquaRest tier actually gets you, what it costs, and which one fits your yard — plus the naming mix-up worth knowing before you comparison-shop across retailers. (Our best plug-and-play hot tub roundup ranks AquaRest against Lifesmart; this is the AquaRest-only deep dive.)
AquaRest hot tubs by the numbers
- $2,699 is AquaRest’s own listed price for the DISCOVER Standard 150 (AR-150), the base tier and this guide’s overall pick, per shopaquarest.com.
- 12 vs. 29 jets — the 150-size tiers (Standard and Premium) run 12 stainless-steel jets, while the 600-size Premium tier jumps to 29, per AquaRest’s product specifications.
- 156 vs. 240 gallons is the water capacity gap between the 4-person 150 tiers and the 6-person Premium 600, per AquaRest — the main reason the bigger spa costs more to run.
- 120V-only vs. convertible 120V/230V — the Standard 150 is fixed at household 120V, while both Premium tiers ship convertible to 230V for a faster-heating 2-speed pump, per AquaRest’s spec sheets.
The 2026 AquaRest lineup at a glance
| Model | Best for | Seats | Jets | Pump | Typical price |
|---|---|---|---|---|---|
| DISCOVER Standard 150 (AR-150) | Best overall | 4 | 12 | 1.5HP, single-speed | ~$2,699 |
| DISCOVER Premium 150 | Best upgrade, same footprint | 4 | 12 | 2HP, 2-speed | ~$2,829 |
| DISCOVER Premium 600 (AR-600) | Best for groups | 6 | 29 | 2HP, 2-speed | ~$3,449 |
Prices checked August 2026 directly against shopaquarest.com; expect Walmart, Wayfair, and Home Depot listings to run a few hundred dollars higher or lower depending on current promotions, and to still show the legacy AR-150/AR-600 model numbers instead of the DISCOVER tier names.
1. AquaRest DISCOVER Standard 150 (AR-150 Select) — Best Overall
AquaRest DISCOVER Standard 150 (AR-150 Select)
- Roto-molded, impact-resistant polyethylene shell — won't crack, peel, or fade like acrylic.
- 12 stainless-steel jets driven by a 1.5HP pump, plus a cascading LED waterfall.
- Plugs into a standard 120V household outlet — no electrician, no 240V line.
- 156-gallon capacity with thermal friction heat recovery and an included locking cover.

The Standard 150 is the AquaRest most people end up buying, and it earns that by doing the basics right: a genuinely durable roto-molded shell, real hydrotherapy jets instead of an inflatable’s air bubbles, and a plug that fits a normal outlet. It skips the ozone system and the convertible-voltage pump that the Premium tier adds, which is exactly how it holds its price near $2,699 while still beating most plug-and-play competitors on shell durability. If you’re moving up from an inflatable specifically for targeted jets rather than bubbles, see our hot tub for back pain guide for why that distinction matters.
2. AquaRest DISCOVER Premium 150 — Best Upgrade, Same Footprint
AquaRest DISCOVER Premium 150
- Same 70" x 60" footprint and 12-jet count as the Standard 150.
- Stronger 2HP, 2-speed pump plus an ozone purification system.
- Convertible 120V/230V heater (1kW/4kW) for faster reheat if you wire it to 230V.
- Full-foam insulation, 9-color LED waterfall, and a 12-ft GFCI cord included.
For roughly $130 more than the Standard 150, the Premium 150 swaps in a genuinely stronger pump and adds an ozone system that cuts down on manual sanitizer dosing — per AquaRest, ozone purification eliminates up to 75% of the chemicals a spa would otherwise need. It’s the same size spa, so the upgrade only makes sense if you’ll actually use the extra pump power or want less chemical maintenance; if neither matters to you, the Standard 150 saves the difference. Either way, budget for test strips and a starter chemical kit regardless of tier.
3. AquaRest DISCOVER Premium 600 (AR-600) — Best for Groups
AquaRest DISCOVER Premium 600 (AR-600)
- 240-gallon shell with barrier-free seating for six and a deep footwell.
- 29 two-tone stainless-steel jets with dual-zone air controls.
- 2HP 2-speed pump, convertible 110V/15A to 230V/30-40A for faster heating.
- Full-foam insulation, ozone system, and a premium thermal-locking cover.
The Premium 600 is AquaRest’s answer for households or entertaining that outgrow a 4-person spa: more than double the jets, 84 more gallons of water, and barrier-free seating that fits six adults without the knee-Tetris of a compact tub. That extra water volume is also why it costs more to run than the 150 tiers — budget toward the higher end of a typical hot tub running cost range, and lean on the included locking cover to claw heat retention back. If six seats is more than you need, the best 6-person hot tub roundup compares this AquaRest tier against other brands at the same capacity.
Decoder: AR-XXX model numbers vs. DISCOVER tier names
AquaRest quietly rebranded its own lineup, and most third-party retailers haven’t caught up — which means the exact same spa can appear under two completely different names depending on where you’re shopping.
| Old model number | Current DISCOVER name | Where you'll see the old name |
|---|---|---|
| AR-150 Select | DISCOVER Standard 150 | Walmart, Wayfair, most third-party retailers |
| AR-150 (higher tier) | DISCOVER Premium 150 | Some retailers, inconsistently |
| AR-600 | DISCOVER Standard/Premium 600 | Walmart, Wayfair, Home Depot |
The practical takeaway: don’t assume two listings with different names are different spas, and don’t assume two listings with the same “AR-600” name are identical either — retailers sometimes apply the old number to whichever jet-count tier they’re currently stocking. Match jet count and gallon capacity against AquaRest’s own current spec sheet before you buy, regardless of which name a listing uses.
How to choose your AquaRest tier
- Match voltage to what you already have. The Standard 150 is 120V-only — the simplest install. Only step up to a Premium tier’s convertible 230V wiring if you’re prepared to run a dedicated circuit; see our hot tub wiring guide for what that circuit actually needs.
- Ozone is a maintenance-time trade, not a must-have. It cuts chemical dosing, not cost — you’re still buying sanitizer and running routine maintenance, just less of it.
- Size for real bodies, not rated seats. The Premium 600’s “6-person” rating is comfortable for 4-5 adults with elbow room; if it’s usually just two of you, the 150 tiers save money on both purchase price and monthly running cost.
- “Jacuzzi pumps” is a component detail, not a Jacuzzi-brand spa. AquaRest licenses Jacuzzi’s pump engineering — a real reliability signal — but AquaRest itself is a separate company from Jacuzzi. If you’re weighing an actual Jacuzzi-brand spa against these, see our hot tub vs Jacuzzi breakdown for the price gap.
- Budget for entry and cover-lifting. These cabinets stand tall enough that most owners add steps and a cover lifter.
The bottom line
The DISCOVER Standard 150 (AR-150 Select) is the best AquaRest hot tub for most buyers — a durable roto-molded spa with real jets on a standard household outlet for around $2,699. Step up to the Premium 150 for a stronger pump and ozone system at the same size, or the Premium 600 (AR-600) if you need to seat six. Whichever tier you pick, remember AquaRest sells it under two names depending on the retailer — match specs, not model numbers.
