Sun Home Cold Plunge Pro Titan Review: 238 Gallons, a Bench, and $14,999 With Code
The largest Sun Home plunge: 238 gallons, a built-in interior bench, waterfall, dual pumps and UV. What it adds over the Pro — and the electrical question to settle before ordering.
Quick Verdict
The biggest and most comfortable plunge Sun Home makes — the only one with seating inside, plus dual pumps and a waterfall. It costs $1,200 more than the Pro, and its dual power supply means you should confirm its electrical needs with Sun Home before you buy.
Pros
- 238 gallons, the largest in the lineup.
- Built-in interior bench for a seated, supported plunge.
- Dual water pumps, dual hair filter plus a 10 by 4.5 dust filter.
- Ozone and UV sanitation with automatic ice-making.
- Interior lighting and a small waterfall feature.
Cons
- $1,200 more than the Pro.
- Dual power supply — confirm the electrical requirement before ordering.
- Largest footprint at 92.9 by 36.6 inches.
- Around 2,000 lb of water alone when full.
The Pro Titan is the most plunge Sun Home sells. Whether you need that much is the whole question.
Quick answer
238 gallons, a built-in interior bench, a small waterfall, dual water pumps, ozone plus UV sanitation, automatic ice-making, and interior lighting, in a tub measuring 92.9” × 36.6” × 40.7”.

What the Titan adds
A bench. This is the genuine differentiator. Every other Sun Home plunge has you sitting on the floor of the tub or reclining. The Titan gives you a built-in seat, which makes longer, more controlled sessions more comfortable — and makes getting in and out easier.
Capacity. 238 gallons against the Pro’s 150. More thermal mass, so the water shifts less when you get in.
Dual pumps and more filtration. A dual hair filter and a 10 × 4.5 dust filter, with ozone and UV sanitation.
The waterfall and interior lighting. Pleasant. Not a reason to spend $1,200.

The electrical question
The Pro and Pro Apex each plug into a single dedicated 120V, 15-amp GFCI outlet. The Titan’s listing specifies a dual power supply, which suggests it may need more than one circuit.
We couldn’t find a published breakdown, so we’re not going to guess. Ask Sun Home exactly what supply the Titan requires, and have an electrician look at your panel if it needs more than you have. An unexpected circuit installation is the fastest way for a $15,000 purchase to become a $17,000 one.
Setting it up
Load. 238 gallons is roughly 1,985 lb of water before the tub. On anything other than a slab or solid ground, confirm the structure.
Space. Nearly 8 feet long and over 3 feet wide. Measure the spot and the delivery route.
Airflow and drainage. Level, sound surface, drainage nearby, clearance around the unit.
Filters: follow Sun Home’s schedule — at least monthly for the Pro Series, more often with daily use.
About the 28°F capability
Like the rest of the Pro Series, the Titan makes ice. Liquid fresh water can’t sit below 32°F, so ice-making means the water around it is at about freezing. Far colder than most people plunge.
Who should buy it
Someone who wants the most comfortable, spacious plunge available from Sun Home, values the bench for longer sessions, and has the space and electrical capacity to support it.
Who should skip it
Most buyers. The Cold Plunge Pro delivers the same stainless construction, sanitation and ice-making for $1,200 less on a standard outlet. If you’re new to plunging, the Horizontal at $3,848 with the filter-pack trick is the sensible start.
On the benefits, conservatively
Cold immersion is associated with reduced perceived muscle soreness and a short-term lift in alertness and mood. Research suggests regular plunging straight after strength training may blunt muscle-building adaptations — separate the two if that matters to you.
The cold shock is a real cardiovascular stress. Never plunge alone, keep early sessions short, avoid it after alcohol, and consult 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. The bench is a genuine comfort upgrade and the capacity is real. For most people, though, the Pro does the job — and before buying the Titan, settle the electrical question.
