THE SMARTER WAY TO START
Get the cold.
Skip the $5,000 setup.
A proper plunge does not need a showroom or a forced $5,000 bundle. Start with ice, then use the built-in ports when you want to add a chiller.

Six layers between your cold and the weather.

The outer shell.
UV-stable fabric on the outside of the tub. Sun, abrasion and the patio edge stop here, so the layers inside never meet the weather.

Straight answers
What buyers ask first.
Can I return it? ›
Returns within 30 days; you cover return shipping. Damage from use is not returnable, but manufacturing defects are covered by the 1-year limited warranty.
How fast is the refund? ›
Refunds start processing within 5 business days of the return scan. That timing is written into our policy, not a support promise.
Is it actually cold enough? ›
The water temperature depends on starting water, ice, weather and routine. The wall helps slow temperature change; Pro models add an insulating air cavity. Use a thermometer and begin gradually.
Will it survive winter and daily use? ›
The six-layer wall exists for exactly that: UV-stable shell, structural weave, dual walls and an inner liner.
Will I fit? ›
The ovals take a full stretch to 6'4" and seat two. The cylinders are a sit-up soak on two feet of floor. The dimensions live in the gallery's "Fits you?" view.
Can the lid hold rain or snow? ›
The lid insulates and keeps out dust and debris. It isn't built to carry weight: clear off rain and snow, or take it off and store it in bad weather.
When does it ship? ›
Free US shipping on every tub, shipped from the US. Exact dispatch times show at checkout.
