Frequently Asked Questions

Everything you need to know before you buy.

How is my cold plunge delivered?

Your cold plunge ships via freight truck (LTL freight). Delivery is curbside β€” the driver will bring it to the end of your driveway. You'll need to arrange moving it inside yourself, or hire a local moving service. You'll receive a call from the freight carrier 24–48 hours before delivery to schedule a window that works for you.

Most cold plunge arrive on a pallet and will require 2 people to carry inside.

What if my cold plunge arrives damaged?

Inspect the packaging carefully before signing for delivery. If you notice any damage to the box or pallet, note it on the delivery receipt and take photos immediately.

Contact us at Sales@Iridescenthome.com or call (307) 201-4597 within 48 hours with your photos. We will work directly with the freight carrier and manufacturer to get replacement parts or a full replacement shipped to you at no extra cost.

Do not refuse delivery β€” accepting damaged freight and documenting it is the fastest path to resolution.

Yes! We offer 0% APR financing through Shop Pay Installments (powered by Affirm). You can split your purchase into equal monthly payments with no interest and no hidden fees.

To use financing, simply select Shop Pay at checkout and choose the installment plan. You'll see your monthly payment amount before you confirm your order. Most customers pay as little as $100–$200/month depending on the model.
