Product Highlights
High-Efficiency Foam Insulation
The roto-molded shell and foam insulation layer work together to retain cold water temperatures significantly longer than uninsulated alternatives. Less ice used per session means lower ongoing costs.
Built-In Chiller Ports
Dual 3/4-inch IN and OUT hose ports are integrated into the tub wall, making it compatible with most residential and commercial water chillers. No drilling or modifications required.
100-Gallon Rectangular Design
At 28" L × 48" W × 28" H, the Frozin 400 provides enough room for full-body immersion for users up to 6'3" tall and 300 lbs. The rectangular shape allows a natural, comfortable seated position.
Heavy-Duty LDPE Construction
Low-Density Polyethylene is impact-resistant, UV-stable, and weather-tolerant. The Frozin 400 is built to remain structurally sound through repeated temperature cycling and outdoor exposure.
Insulated Lid Included
The included insulated lid helps maintain water temperature between sessions and keeps debris out when the tub is not in use.
Easy to Clean and Maintain
The smooth, polished interior surface resists buildup and wipes down easily. A standard drain plug allows for quick water removal without lifting or tipping the tub.

Frequently Asked Questions
Does the Frozin 400 come with a chiller, or is it sold separately?
The Frozin 400 includes the insulated tub and lid only. A water chiller is not included but can be connected using the built-in 3/4-inch IN and OUT hose ports. The tub is compatible with most residential and commercial water chillers available on the market.
Can I use this tub with ice instead of a chiller?
Yes. The Frozin 400 works well with ice alone. The high-efficiency foam insulation helps retain cold temperatures longer than uninsulated tubs, reducing the amount of ice needed per session.
What is the maximum user size this tub accommodates?
The Frozin 400 is designed to comfortably fit individuals up to 6'3" tall and 300 lbs. The rectangular shape allows for a natural seated immersion position.
Is the Frozin 400 suitable for outdoor use year-round?
Yes. The roto-molded LDPE construction is UV-stable and weather-resistant, making it suitable for outdoor use in most climates. In freezing conditions, drain the tub when not in use to prevent water from expanding inside the shell.
How do I drain the tub?
The Frozin 400 includes a standard drain plug. Open the plug to drain water directly onto the ground or connect a hose for directed drainage. The smooth interior makes it easy to wipe down after draining.
Does this tub require any assembly or installation?
No tools or installation are required. The Frozin 400 is freestanding and arrives ready to use. Simply place it on a flat, level surface, connect your chiller or add ice, and fill with water.
