Freight shipping: $495 to the contiguous United States. Delivery is curbside only. White glove placement and installation are not available with this listing. Remote locations or difficult access may require additional charges.
A Compact Tub for Your Immersion Space
Black Finish & Fiberglass
The thermally modified pine surround pairs with a contoured fiberglass insert. The black-painted finish complements contemporary patios and darker sauna exteriors.
One-Person Format
The upright tub has a 124-gallon capacity and a 40-inch exterior diameter. Allow additional space for stairs and safe entry and exit.
Ready for Compatible Equipment
3/4-inch NPT connections allow integration with compatible temperature-control equipment. Confirm compatibility and required accessories before purchasing a separate chiller/heater.
Assembled Tub & Matching Stairs
The tub arrives assembled with Round Deluxe Stairs. Final placement, water handling, and any equipment connections still need to be arranged.

Choose How You Manage Water Temperature
The S1B itself does not actively heat, cool, circulate, or filter water. Without added equipment, temperature depends on the fill water and surrounding conditions.
For maintained temperatures, ask us to review compatible chiller/heater options and their connection, electrical, filtration, and placement requirements. Follow the tub and equipment manuals for permitted temperatures and startup procedures.
Operating costs depend on water changes, local utility rates, climate, cover use, and the equipment selected.
Prepare Your Site Before Delivery
- Support: Provide a stable, level base rated for the tub, water, bather, and any added equipment. Have elevated decks assessed by a qualified professional.
- Access: Check crate dimensions and the full route from the curb to the final location. Arrange the crew and equipment needed for placement.
- Water handling: Plan filling, drainage, spills, cleaning, and routine water changes. Follow the manufacturer's water-care instructions.
- Optional equipment: Allow airflow and service access around any chiller/heater. Have a licensed electrician verify its required supply and protection.
- Seasonal care: Follow the manufacturer's winterization instructions for the tub, drain, lines, and any connected equipment before freezing conditions.
Use the installation manual for final planning. An assembled tub still requires preparation and setup before bathing.
Warranty & Product Documents
SaunaLife's current limited warranty provides two years of residential coverage for qualifying workmanship defects after delivery to the original retail purchaser. Exclusions include normal wear, natural wood weathering, user damage, and installation or delivery costs.
Commercial use is excluded under this warranty. Added equipment has its own warranty terms.
Delivery & Returns
The $495 freight rate covers standard curbside delivery within the contiguous United States. Confirm access restrictions and additional charges before shipment. You are responsible for arranging the move from the curb to the prepared site.
Inspect the shipment at delivery, record visible damage or shortages on the delivery receipt, and contact us promptly with photographs if there is a problem. Retain the packaging.
Review the current return policy before ordering. Eligible Bathing Brands returns must be completed within 30 calendar days of purchase and require new, uninstalled merchandise and written authorization. Return freight and other disclosed costs may apply.
SaunaLife S1B FAQs
Does the S1B include a chiller or heater?
No. This is the tub-only listing. Compatible temperature-control equipment and any required connection accessories are sold separately.
How is the S1B different from the S1BC package?
The S1B is the black-finish immersion tub. The S1BC package combines that tub with a chiller/heater and listed equipment accessories.
Are stairs and a cover included?
Round Deluxe Stairs are included. A compatible tub cover is a separate accessory unless added to your order.
Does the tub arrive ready to bathe in?
The tub arrives assembled, but you must arrange final placement, drainage, filling, water care, and any optional equipment connections before use.
How should I prepare it for freezing weather?
Follow SaunaLife's current winterization instructions and those for any connected equipment. Protect the tub, drain, and lines before freezing conditions; a cover alone does not provide freeze protection.
