How does delivery work?

Freight, not parcel. Shipping is quoted per model and charged at checkout, and you see the exact figure before you pay.

When it ships. Stock across a range this size moves week to week, so we confirm the position for your model when you order rather than publishing an average that would be wrong for half the catalog.

How you will know. You get a tracking notification by email once your order ships. On a freight shipment the updates come from the carrier's own portal rather than standard UPS or FedEx tracking, so we include the carrier name, the PRO tracking number and a link to their tracking tool.

How it arrives. Palletized on an LTL carrier, or on a flat bed for the largest cabins. The carrier calls to arrange a window, someone must be there to sign, and delivery is to the curb. Pallets run up to 81 inches wide, so check the route from where a truck can stop to where the sauna will sit before you order.

Where it ships. Rates cover the contiguous 48 states. Canada is higher and set by SaunaLife, and Alaska, Hawaii and Puerto Rico are always quoted case by case, so contact us before ordering.

If it arrives damaged. Inspect every crate with the driver still there and write any damage on the delivery receipt before you sign. SaunaLife excludes damage that would have been visible on inspection, so a clean signature can cost you the claim. Call us from the driveway.

Read the full SaunaLife Shipping & Delivery Policy

What does the warranty cover?

Two years, residential. Defects in workmanship under normal use, from the date you take delivery, to the original retail purchaser. Keep your receipt.

Repair or replace. SaunaLife chooses which, and may substitute a component of equivalent value. A replaced part carries the remaining term rather than starting a new one.

Not covered. Installation and delivery, normal wear, user damage, and the way wood behaves: knots, grain and tone differences, shrinkage, moderate deformation and weathering. Accessories carry one year. Cleaners, wax, paint and oils carry 60 days.

Residential only. Commercial use voids it, so call before you order if the sauna goes into a gym, spa, clinic or any other business and we will confirm the terms in writing.

The heater is separate. A SaunaLife sauna does not include a heater, so the heater, its control unit and its stones fall under that manufacturer's warranty.

Transport damage must be caught on delivery. Damage that would have been detectable by visual inspection before installation is excluded. Inspect the crates with the driver, write any damage on the delivery receipt before you sign, and photograph everything before you move it. Once panels are assembled, a claim for damage that was visible beforehand is very hard to win.

Who handles it. We handle the claim with SaunaLife for you. Call (888) 500-5675 with your order number, photographs and a description of the fault.

Read the full SaunaLife Warranty Policy

What if I need to return it?

30 days from purchase. The unit must be new, uninstalled and in resalable condition with its original crating and all included parts. Once panels have been screwed together, a tub has been filled or a stove has been fired, it counts as installed and cannot be returned.

What a return costs. A 20 percent restocking fee may be deducted from your refund on a standard customer return.

Who pays the freight. You do on a change of mind, and on a crated sauna that is a real number rather than a formality, so ask us for a figure before you commit. The freight you paid at checkout is not refunded either.

When it is our fault. If the cause is shipping damage or an error on our side, we and the distributor cover the return and nothing is deducted.

Damaged on arrival. A different process, and it is time sensitive. Note the damage on the delivery receipt before you sign, photograph the crates before you move anything, and call us the same day. Transit damage is resolved by replacement parts rather than by return.

Cancelling before it ships. No fee at all before we submit your order to the manufacturer. After we submit it but before it ships, an administrative fee of up to 5 percent may apply, and we waive it whenever we are not charged.

To start a return. Call (888) 500-5675. A Return Authorization number is required before anything goes back.

Shipping and delivery

How the S1 tub is delivered

Freight, not parcel

The S1 ships by palleted/LTL freight on a pallet at 265 lbs (120 kg). A freight carrier calls to schedule a delivery window.

Inspect before you sign

Inspect the crates with the driver and write any damage on the delivery receipt. Damage that was visible before assembly is not covered by the manufacturer warranty, so call us from the driveway before you sign for anything that looks wrong.

Check your access

The pallet is 47.8" W x 46" D x 48.1" H. Measure gates, paths and turns before delivery day, because a standard side gate is often narrower than that.

Assembly

Setting up the S1

Level base

Site it on a flat, level, load bearing surface that can carry the tub plus water and a bather.

Chiller connections

Threaded connections are built in. A chiller needs its own outdoor rated circuit, which is an electrician job.

Drain access

Leave room to reach the drain fitting so the tub can be emptied and cleaned without moving it.

FAQ

SaunaLife S1 questions buyers ask before ordering

Does it come with a chiller?

No. The tub ships with threaded chiller connections built in, so you can add a chiller whenever you are ready, or fill it with ice in the meantime.

Does the chiller need power?

Yes. A chiller needs its own outdoor rated circuit, which is an electrician job. The tub itself needs nothing.

How is it delivered, and will the pallet fit through my gate?

By freight carrier on a pallet measuring 47.8" W x 46" D x 48.1" H, at 265 lbs (120 kg), delivered to the curb. That is wider than many side gates, so measure your access before delivery day. The carrier calls you to arrange a window.

What if it arrives damaged?

Inspect the crates with the driver and write any damage on the delivery receipt before you sign. Damage that was visible before assembly is not covered by the manufacturer warranty, so call us from the driveway if anything looks wrong.

What does it sit on?

A flat, level, load bearing surface that can carry the finished weight, including water and bathers. Talk to us about your site before you order.

Can it stay outside all year?

Yes. The shell is thermally treated wood around a fiberglass insert, both made for outdoor use. In a freezing climate do not leave it full and unheated, and follow the care guide for annual upkeep.

What is the warranty?

SaunaLife covers it against defects in workmanship for two years in residential use, to the original retail purchaser. Normal weathering of the wood, user damage and installation are excluded.
