Sun Home Cold Plunge Pro Apex Review: Deeper Water, Smaller Footprint
180 gallons in a 60.5-inch-tall stainless tub — shorter and narrower than the Pro, but deeper. $14,799 with code WELLWORTHIT, and the setup checks that matter for a 2,000-lb plunge.
Quick Verdict
The Pro Series plunge for depth over length. The Apex holds 30 more gallons than the Pro on a smaller floor footprint by going upward to 60.5 inches — useful where floor space is tight, but you pay $1,000 more and carry roughly 2,030 lb when full.
Pros
- 180 gallons — 30 more than the Pro.
- Smaller floor footprint than the Pro at 71.5 by 30.75 inches.
- Same 316 stainless basin, ozone, UV and dual-pump filtration as the Pro.
- Automatic ice-making, touchscreen and Wi-Fi app.
- Standard 120V, 15-amp GFCI plug with no hardwiring.
Cons
- $1,000 more than the Pro for 30 extra gallons.
- 60.5 inches tall — step-in height and overhead clearance need checking.
- Roughly 2,030 lb when full, a concentrated floor load.
- 528 lb empty, which makes delivery and placement harder.
The Pro Apex is the Cold Plunge Pro rethought for depth. Same stainless construction and sanitation, different shape — and that shape is the whole decision.
Quick answer
180 gallons in a 316 stainless tub measuring 71.5” × 30.75” × 60.5”, with ozone, UV, dual-pump filtration, automatic ice-making, and a standard wall plug. It uses less floor than the Pro, stands nearly twice as tall, and holds 30 more gallons.

When the Apex makes sense
Your constraint is floor, not height. A narrower, shorter footprint fits spaces where the Pro’s 6.5-foot length won’t.
You want deeper immersion. More water volume in a taller tub.
It does not make sense if floor space isn’t tight. Then you’re paying $1,000 for 30 gallons and a harder step-in.
The setup checks
Height. At 60.5 inches, measure your step-in and your overhead clearance, especially indoors. It ships with stair mats, which tells you getting in is a real consideration.
Load. Roughly 2,030 lb filled, concentrated on a smaller footprint than the Pro. On anything other than a slab or solid ground, confirm the structure.
Delivery. 528 lb empty. Plan the route and the people.
Airflow and drainage. Sun Home asks for 12 inches at the sides and 36 at the front, on a level, sound surface with drainage nearby.
First cool-down: 6–8 hours, faster with the lid on. Filters monthly, every two weeks for daily use.
About the 28°F setpoint
As with every Pro Series plunge: liquid fresh water freezes at 32°F, so the 28°F setting means the system makes ice while the water sits around freezing. Real ice-bath capability — far colder than typical plunging.
Who should buy it
Someone who wants a permanent stainless plunge with deep immersion, and whose space has more height than floor.
Who should skip it
Most people choosing within the Pro Series. If floor space isn’t the problem, the Cold Plunge Pro is $1,000 less and easier to get in and out of. If you want seating inside the tub, that’s the Pro Titan. If you’re new to plunging, start with the Horizontal.
On the benefits, conservatively
Cold immersion is associated with reduced perceived muscle soreness and a short-term lift in alertness. Research suggests plunging straight after strength training may blunt muscle-building adaptations — separate them if that matters to you.
The cold shock is a genuine cardiovascular stress. Never plunge alone, keep early sessions short, avoid it after alcohol, and speak to a doctor first if you have a heart condition, high blood pressure, Raynaud’s, are pregnant, or take medication affecting circulation.
Final verdict
Good, but not essential. A well-built plunge that solves a specific space problem. If that’s your problem, it’s the right tub; if it isn’t, the Pro is better value.
