Can a cold plunge be built in the ground?
Yes. We build cold plunges for in-ground, flush-mount and deck-level installs, in any size, shape or depth.
An in-ground build uses the same layout as our Modular. The tub is one piece and the equipment is another. The tub goes into the recess. The component box holds the chiller, the pumps and the filtration.
Where does the equipment go?
The component box can sit up to 25 feet from the tub, and the plumbing between them can pass through a wall. On past builds the box has gone on a roof, and one tub sits five feet above its box.
The tub frame has no clearance requirement. The component box needs 18 inches of clearance at its vents. Keeping the box away from the tub also keeps its noise and heat away from the tub.
How does an in-ground cold plunge drain?
We have built tubs with a pop-up drain and hard plumbing. The plumbing in the unit is 1.5-inch PVC. Where the drain line runs from there depends on the site, and you get the drainage needs up front.
Who builds the recess and who sets the tub?
Your contractor does. Our engineer draws the tub and you get the design. We weld, finish and test the tub and the equipment in our shop, and your builder or pool builder sets it.
The plumbing between the tub and the component box is run on site by a plumber or general contractor, in schedule 40 PVC, fully insulated to limit cold loss. It is not included in what we ship.
What is the tub made of?
The standard tub is 14-gauge 316 stainless steel. Carbon fiber, HempCarbon and gel-coated fiberglass are available, and a stainless tub can be powder-coated in any color.
Every build has RiverMode, a current driven by magnetic-drive pumps, with 20-micron filtration and ozone. The water holds anywhere from 34°F to 70°F. It is cold only.
