Frequently Asked Questions

Before You Buy

How do I choose between a cold plunge and an infrared sauna?

They serve different goals. Cold plunges are typically used for post-workout recovery, inflammation reduction, mental alertness, and resilience training. Infrared saunas are used for relaxation, cardiovascular support, detoxification, and sleep quality. Many of our customers eventually own both and alternate between them — contrast therapy refers to using cold and heat in sequence, which research suggests may amplify the benefits of each. If you're starting with one, choose based on your primary goal: cold for recovery and activation, heat for relaxation and recovery support.

What size cold plunge do I need?

Cold plunges are sized by interior dimensions and depth. Most adults are comfortable in a tub with at least 64 inches of interior length and 24-28 inches of depth. If you're over six feet tall, look for 70+ inches of interior length. We list precise interior and exterior dimensions on every product page so you can measure your space before ordering.

How much space do I need for an infrared sauna?

A one-person sauna needs roughly 3 x 4 feet of floor space plus clearance for the door to open outward. Two-person saunas need around 4 x 5 feet. Three-person and larger units scale up from there. You'll also need at least 7 feet of ceiling clearance for most models. Specific dimensions are on each product listing.

Do I need a dedicated electrical circuit?

Most cold plunges run on standard 110V household outlets, though some commercial-grade chillers require 220V. Infrared saunas typically run on 110V, though some larger models may require 220V — each product page lists exact requirements. We recommend checking with a licensed electrician if you're unsure about your home's capacity.

Can these be used indoors and outdoors?

It depends on the specific product. Some cold plunges are rated for indoor or covered outdoor use only, while others are designed to withstand direct sun, rain, and freeze conditions. Saunas vary similarly. We note indoor/outdoor ratings clearly on every listing.

Shipping & Delivery

How much does shipping cost?

Shipping is free on every order within the contiguous United States. Some oversized or remote-area orders may require additional handling — if that applies to your order, we'll contact you before charging anything additional, and you can cancel for a full refund.

How long does delivery take?

Orders are processed within 3–5 business days, and total delivery time is typically 15–30 business days from order to arrival for our cold plunges and saunas. Each product page lists current estimates, and we'll send tracking as soon as your order ships.

Do you ship to Alaska, Hawaii, or internationally?

Currently we ship within the contiguous 48 states only. Shipping to Alaska, Hawaii, and international destinations is sometimes possible by special arrangement — contact us before ordering and we'll see what we can do.

How will my order be delivered?

Cold plunges and infrared saunas are shipped via freight carrier, not standard parcel services. Freight delivery means the carrier will call you to schedule a delivery window. Delivery is curbside — the driver will lower the crate from the truck to the ground at the end of your driveway. You're responsible for moving it from there to its final location, which may require help.

What if the product is damaged in shipping?

Inspect every shipment carefully before signing the delivery receipt. If you see visible damage to the crate or packaging, note it on the receipt before the driver leaves. Take photos. Then contact us within 7 days and we'll handle the replacement or repair process with the manufacturer. Do not sign for shipments as "received in good condition" without inspecting first — this significantly affects your ability to file a damage claim.

Setup & Use

Is assembly included?

Most cold plunges arrive fully assembled and ready to use after filling with water. Most infrared saunas arrive in pre-built panels that connect together — typical assembly takes 2-4 hours with two people and basic tools. Each product page details the assembly required.

How often do I need to change the water in my cold plunge?

This depends on the filtration and sanitation setup, which varies by unit. We'll walk you through water care for your specific plunge on your setup consultation, and include the manufacturer's maintenance guidance with every order, so you can keep your water clean with minimal effort.

What's the recommended cold plunge protocol?

This varies by goal and experience level. A common starting point is 2-3 minutes at 50-55°F, 2-3 times per week. More experienced users may go colder (38-45°F) for shorter durations. We recommend consulting with your physician before starting cold exposure therapy, particularly if you have cardiovascular conditions, are pregnant, or are managing any chronic illness.

How often should I use an infrared sauna?

Typical use ranges from 3-5 sessions per week at 20-45 minutes each, depending on temperature tolerance and goals. As with cold exposure, consult your physician before starting regular sauna use if you have any underlying health conditions.

Returns, Warranty & Support

What's your return policy?

Because these are large, made-to-order units shipped by freight, all sales are final — with one exception: units that arrive damaged or defective. If anything arrives damaged, report it within 7 days of delivery with photos and we'll arrange a repair or replacement at no cost to you. This is also why we include a free consultation before you buy — we'd rather help you choose the right unit than have you end up with one that doesn't fit. Full details are on our Refund Policy page.

What's the warranty?

Our cold plunge and infrared saunas are backed by a 1-year limited warranty. For the Frost cold plunge, that covers the tub body, plumbing, and integrated chiller. For the Lumin saunas, it covers the heating panels, control systems, wood structure, and electrical components for residential use. Coverage begins the day your product arrives, and we help facilitate every warranty claim directly with the manufacturer on your behalf. Full terms are on our warranty page.

How do I contact you with questions?

Email us at hello@stonehavenrecovery.com or use the contact form on our Contact page. We respond to every inquiry within one business day, often the same day during business hours. Our hours are Monday-Friday, 9am-6pm Eastern. For pre-purchase questions about fit, electrical requirements, or product selection, we'd rather take a phone or video call than rush you through email — just ask.

Do you offer financing?

Yes. We offer financing through Shop Pay Installments at checkout. Your available terms and monthly payment depend on the product price, the plan you choose, and your creditworthiness — so we don't quote specific monthly figures in advance, since they vary from person to person. You'll see your exact options and payment amounts at checkout once you've selected your product, with no impact to your credit score to check.
