This 8-person inflatable hot tub is built with drop-stitch construction — the same technology used in professional-grade paddleboards — giving the walls the rigidity of a traditional hard-shell spa without any permanent installation. With 180 bubble jets, a digital heater that reaches 104°F, and a foil-lined thermal cover that retains heat between sessions, it delivers a consistent, comfortable soak for the whole family. Set it up on any flat outdoor surface and have it ready in under an hour.

Product Highlights
Drop-Stitch Construction
Unlike standard inflatable tubs, the drop-stitch sidewalls are reinforced with thousands of internal threads, creating firm, rigid walls that hold their shape under load and allow comfortable edge seating.
180 Bubble Massage Jets
Jets are distributed around the interior perimeter to deliver consistent, full-coverage bubble massage. The output is adjustable from the digital control panel without leaving the water.
Digital Heating System with Energy-Saving Timer
The smart digital heater warms water to your chosen temperature up to 104°F. The built-in timer lets you schedule heating in advance so the tub is ready when you are — without running continuously.
Foil-Lined Thermal Cover
The insulating cover features an interior foil lining that reflects heat back into the water, reducing heat loss between uses. Child safety locks secure the cover when the tub is unattended.
Natural Stone Exterior Design
The stone-pattern exterior gives the tub a structured, upscale appearance that blends naturally into backyard and patio settings without looking like temporary equipment.
Complete Accessory Kit
Every unit ships with a matching ground mat to protect the base, a high-pressure hand pump for inflation, and replaceable filter cartridges — everything needed to get started immediately.
Seasonal Portability
When not in use, the tub deflates and folds down for compact off-season storage. No permanent structure, no contractor, no permit required.

Frequently Asked Questions
How is drop-stitch construction different from a standard inflatable tub?
Drop-stitch construction uses thousands of internal polyester threads that connect the top and bottom layers of the sidewall. When inflated, these threads create a rigid, board-like wall that holds its shape under load — unlike standard single-layer inflatables that bow outward. This allows you to sit on the edge comfortably and gives the tub a firmer, more stable feel overall.
How long does setup take?
Most setups take 45–60 minutes, including inflation, filling with water, and initial heating. The included hand pump and straightforward design keep the process simple — no special tools or professional installation required.
How long does it take to reach 104°F?
Heating time depends on the starting water temperature and ambient outdoor temperature. In typical conditions, expect 1.5 to 3 hours to reach maximum temperature. Using the insulating thermal cover during heating significantly reduces wait time. The built-in timer lets you schedule heating so the tub is ready in advance.
Can I leave it set up year-round?
The tub is designed for outdoor use in moderate to warm conditions. In freezing temperatures, water left in the tub may damage the unit. It is recommended to drain and deflate the tub before temperatures drop to freezing, or take steps to protect and insulate the water if operating in cold climates. Refer to the instruction manual for cold-weather guidance.
What chemicals do I need for water maintenance?
Standard hot tub chemicals — such as chlorine or bromine sanitizers, pH balancer, and shock treatment — are recommended to keep the water safe and clear. These are not included and should be purchased separately. Follow the water care guidelines in the included instruction manual.
How often do the filter cartridges need to be replaced?
Replacement frequency depends on usage and water quality, but generally every 2–4 weeks is recommended. Replacement cartridges compatible with this model are available separately.
Does the energy-saving timer turn the heater off automatically?
Yes. The digital control panel includes a programmable timer that allows you to schedule when the heater runs, helping to reduce energy consumption when the tub is not in use.
