PRICE PROMISE
PRICE PROMISE
Fair Pricing, Every Time
As an authorized dealer, our prices reflect each manufacturer's approved pricing. That means the price you see here follows the manufacturer's own pricing.
Found a Lower Price?
If you've found the identical product advertised for less by another authorized dealer, email info@plungeintosaunas.com with a link. We'll review it, and if it's a genuine authorized listing we'll match it where the manufacturer permits.
Listings from unauthorized sellers, marketplaces, refurbished or open-box units, and clearance items aren't eligible — those products typically carry no manufacturer warranty.
Why Buying Authorized Matters
Authorized purchases come with full manufacturer warranty coverage, genuine parts, and factory support. A cheaper unit from an unauthorized seller usually has none of that.
SHIPPING POLICY
SHIPPING POLICY
Shipping Information
Most in-stock orders ship within 3–5 business days, with delivery typically taking 5–15 business days after shipment. Sauna cabins and larger units are often made to order and may require additional lead time, which we'll confirm before you buy.
Large items ship by freight carrier, curbside delivery. Cabins frequently arrive on two or more pallets. The carrier will contact you to schedule an appointment, and someone must be present to receive and inspect the shipment. Curbside means the driver delivers to the end of your driveway — moving, unpacking, assembly, and installation are not included.
Inspect your shipment before signing. Count the pallets, note any damage on the delivery receipt, take photos, and contact info@plungeintosaunas.com within 48 hours. Keep all packaging for up to 60 days in case the carrier needs to inspect it.
Delivery dates are estimates and may vary due to carrier delays, weather, or supplier lead times.
RETURN POLICY
RETURN POLICY
Return Information
Return requests must be approved in writing before any item is sent back — return addresses vary by supplier, and unauthorized returns may be refused or ineligible for refund.
The return window is 30 days on most brands. It runs from the delivery date on most lines, and from the purchase date on our Bathing Brands lines (Harvia, HUUM, SaunaLife, Saunum, Delta, Kohler, ThermaSol, Bathology, Cozy Heat, Rento, Hukka, EOS, AromaMist, Narvi, Finnmark, Kolo, 4 Living and Hotass Saunas).
Eligible products must be unused, uninstalled, unassembled, complete, and in original packaging. You are responsible for return shipping on a change-of-mind return. Fees vary by brand — some lines charge a restocking fee of up to 25%, while the Bathing Brands lines charge no restocking fee, only a re-boxing fee of roughly $20 to $50 if the original packaging is not returned intact.
If the item arrived damaged or a manufacturer error is at fault, return shipping is covered for you.
Custom, made-to-order, special-order, clearance, installed, assembled, or final-sale products may not be returnable.
Damaged, missing, or incorrect items must be reported to info@plungeintosaunas.com within 48 hours of delivery.

Manuals & documents
Shipping & delivery
Shipping cost: Shipping on this item is a flat $495 per order within the contiguous US, added at checkout before you pay.
Most in-stock orders ship within 3–5 business days of confirmed payment, and delivery is typically 5–15 business days after shipment. Made-to-order saunas and custom-configured rooms need production time on top of that, which we confirm before the order is released. We ship within the contiguous United States.
Large items ship LTL freight on a pallet, delivered curbside — to the curb or the end of your driveway, often from a trailer up to 53 feet long. Curbside does not include unpacking, assembly, installation or electrical connection. The carrier calls to book an appointment and someone must be there to receive the shipment. Tell us at the time of order if access is limited — narrow or rural roads, steep driveways, gated communities — and ask for liftgate service if you have no dock or forklift.
Inspect the shipment before the driver leaves and before you sign. Count the cartons and pallets against the paperwork, check glass doors and panels, write any damage or shortage on the Delivery Receipt, and photograph it. Email info@plungeintosaunas.com within 48 hours of delivery with your order number, photos and the noted receipt — the same window covers concealed damage and missing items. Keep the packaging while a claim is open.
Cancellations & returns
Cancel before the order has been submitted for fulfillment and it is refunded in full — email info@plungeintosaunas.com with your order number. After that point manufacturer, carrier, return-freight or restocking fees may apply. Every return must be approved by us in writing first: products ship from different manufacturer warehouses, so the correct return address varies, and anything sent back without authorization may be refused.
Return requests are made within 30 days under our general policy; some brands run that window from the date of purchase rather than delivery. Items must be unused, uninstalled, never heated or filled, complete in their original packaging and in resalable condition. Restocking fees run up to 25% depending on the manufacturer, while Harvia, HUUM, SaunaLife, Saunum, Narvi, ThermaSol, Delta, Kohler and Mr. Steam charge no restocking fee at all, only a re-boxing fee of roughly $20–$50 if the original packaging does not come back intact. On a change-of-mind return you pay return shipping and the original outbound shipping is not refunded.
If the item arrived damaged or a manufacturer error is at fault, return shipping is covered for you. Custom, made-to-order and special-order items already in production, clearance and open-box items, heaters that have been wired or fired, tubs and generators that have been filled, assembled or heated rooms, opened consumables and all Canadian Timber Collection products cannot be returned. Ask us before you buy if you are unsure.

Setting up
What happens between checkout and your first session.
-
The S1B ships at 265 lbs (120kg). Curbside delivery by appointment, palletized. You'll need a clear path and at least two people to move it to its spot.
-
Chillers and heaters plug into a standard outdoor-rated GFCI outlet unless the spec table says otherwise; keep the unit within reach of the outlet and the hose. Fill from a garden hose — no plumbing needed.
-
It measures 41.3 "H (105cm) x 40" Diameter (102cm). Filled, it is far heavier than it ships — water alone runs about 8.3 lb per gallon — so set it on a level concrete pad, patio or a deck rated for the filled load, with room around it for the cover and for stepping in and out.
