Cold plunges for builders and general contractors.

You get the power, drainage and access needs up front.

What power does a cold plunge need?

A Modular needs a dedicated 110/120-volt, 20-amp circuit. It ships with a GFCI plug in a NEMA 5-20P configuration, so the outlet has to accept that plug.

A custom build can differ. Its power, drainage and access needs are settled in design and you get them up front.

What plumbing is on your side?

The run between the tub and the component box. It is done on site by a plumber or general contractor and is not included in what we ship. Use schedule 40 PVC and insulate it fully to limit cold loss. The plumbing inside the unit is 1.5-inch PVC.

The box can be up to 25 feet from the tub, and the run can pass through a wall.

What clearances does it need?

The tub frame has no clearance requirement. Keep the unions and the plumbing connection to the box reachable. The component box needs 18 inches of clearance at its vents.

How does it arrive?

Fully assembled, in a palletized crate, dropped off curbside. Bring screw guns to open the crate. Plan on four movers with moving dollies. A Modular tub frame is 28.5 inches tall and can be tilted on its side to pass through interior doors and narrow hallways.

Filling the tub takes 10 to 15 minutes, depending on water pressure.

Who can service it?

The compartments are large and can be serviced by plumbers and pool and spa technicians. We run live video technical support Monday through Friday, 9 am to 5 pm Pacific.

Common questions

Can the equipment sit on the other side of a wall?

Yes. The tub can be plumbed through a wall to the component box, up to 25 feet away.

What is it made of?
