No more ice runs. Just set your temperature, open the app, and plunge.

The Golden Designs Cold Therapy Premier Edition Chiller transforms any cold plunge tub into a fully automated, temperature-controlled wellness system. Cool your water down to a crisp 37°F — or warm it up to 85°F for contrast therapy — without ever touching a bag of ice. The WiFi-enabled Tuya Smart app lets you power on, adjust temperature, set schedules, and monitor performance from anywhere with a connection.

Built for seamless integration with Golden Designs Cold Therapy tubs, this chiller is available in 0.8 HP (up to 135 gallons) and 1.0 HP configurations. The built-in two-stage filtration system with 20-micron replaceable filters and automated natural ozone sanitation keeps your water crystal clear between sessions — no complicated maintenance routines required. A splash-proof digital touchscreen gives you direct control when you're right at the tub.

Runs on a standard 120V outlet with a built-in GFCI — no special electrical required. Quick-connect hoses, a pre-installed filter plus one replacement, and a filter housing wrench are all included.

Frequently Asked Questions

What is the difference between the 0.8 HP and 1.0 HP chiller?
Both chillers offer the same temperature range (37°F–85°F), WiFi app control, ozone filtration, and features. The 1.0 HP compressor has more cooling power — it reaches target temperatures faster and maintains them more efficiently in warmer ambient conditions or larger water volumes. The 0.8 HP is ideal for most standard cold plunge tubs up to 135 gallons. Choose the 1.0 HP if you have a larger tub, live in a hot climate, or want faster cool-down times.

Which Golden Designs cold plunge tubs is this chiller compatible with?
This chiller is compatible with all Golden Designs Cold Therapy tubs — including the Cuboid, Cuboid XL, Cold Plunge Tub (304 Stainless), Barrel Cold Plunges (stainless and PVC), and Oval Barrel. It connects via quick-connect hoses included in the box. Confirm your tub's gallon capacity against the chiller's rated capacity before ordering.

Does the chiller require special electrical installation?
No. The chiller runs on a standard 120V household outlet with a built-in GFCI — the same as most home appliances. No dedicated circuit or licensed electrician is required. Simply plug it in and connect the hoses to your tub.

How does the WiFi app control work?
The chiller connects to the Tuya Smart app (iOS and Android). From the app, you can power the chiller on/off, set your target temperature, create schedules (e.g., pre-cool before your morning session), and monitor real-time water temperature and chiller status from anywhere with a WiFi connection.

How fast does the chiller cool the water?
The chiller cools water at approximately 1–3°F every 30 minutes, depending on ambient temperature, starting water temperature, and tub volume. For a standard 80–100 gallon tub starting at room temperature, expect 2–4 hours to reach 50°F. Pre-scheduling via the app the night before or a few hours ahead is recommended for morning sessions.

How does the ozone sanitation system work?
The chiller includes an automated natural ozone generator that continuously sanitizes the water without harsh chemicals. Ozone is one of the most effective natural sanitizers available — it breaks down bacteria, viruses, and organic contaminants without leaving chemical residue. This significantly reduces how often you need to drain and refill the tub.

Can the chiller be used outdoors?
The chiller is rated for indoor use and covered outdoor installations — such as a covered patio, pergola, or enclosed outdoor structure. It should not be exposed to direct rain or standing water. The tub itself can be fully outdoors; the chiller should be positioned in a covered area nearby.

How is the chiller delivered?
The chiller ships via standard freight or parcel at 62 lbs and is delivered curbside. It is compact enough (20"L × 13"W × 18"H) to be moved by one person to its installation location.
