HB21O Product Description

Using the same elegant oval design, the Hudson Bay HB21O 5 person hot tub is a step up from it's sister, the HB14O.  As Hudson Bay's biggest round hot tub model, this spa adds jets to the two single corner seats and increasing the comfort of up to five guests. Hudson Bay spas are known for packing the high-quality features of a standard 220v spa into the ease and convenience of an 110v 'plug and play' model.

The ultimate benefit of a ‘plug n play” hot tub is the fact that it is ready out of the box, all you need to do is plug it into any existing wall outlet, fill with water, heat, and enjoy! Your spa will be a hot and steamy within 24 hours.

Maximize your relaxation and soothe away any aches and pains that you encounter in your daily life with 14 adjustable hydrotherapy jets, which are conveniently placed to target specific pain points. The super powerful 2 hp pump delivers a penetrating stream to ensure that all Hudson Bay models pack the same punch, no matter what their size.

The colored LED lights and backlit waterfall give some additional ambiance to your retreat and the synthetic wood cabinetry gives the HB21O 5 person hot tub the added elegance of a classic spa look.

With easy to use controls, including an energy saver mode to cut back on that electric bill, this model offers all the functionality and standard features of a classic full-sized tub. It is also Ozonator ready! Just check out our upgrades tab and get ready to cut back on chemical use and maintenance!

Every Hudson Bay Spa is lined with multi-layered fiberglass reinforcements to ensure the integrity of the spa last for many years. Additional to the fiberglass reinforcements, an ABS bottom protects the spa from any sort of erosion and weather wear. Every spa is also plumbed using HeatFlow™ manifolds that help retain the heat throughout the pipe and 100% anti-fungicide tubing to prevent nasty bacteria build up in the plumbing lines, which results in much cleaner waters with the use of less chemicals.  Warranty

Ozonator Upgrade

Adding an Ozonator to your spa is the ultimate way to keep your spa clean. With little to no maintenance required.

Your Ozonator will keep your spa clean by sending ozone molecules (when three oxygen molecules are combined) through the water, which oxidizes the contaminants in the water. An Ozonator helps:

  • Reduce the amount and cost of harmful chemicals needed in your spa.
  • Destroys bacteria, algae, virus and other contaminants. 
  • Greatly prolongs the life of your spa equipment.
  • Reduces YOUR time and maintenance required.

***An Ozonator complements your spa system it does not replace sanitizer systems or chemicals.***

Cover Concierge 

Covers can be hard to open and close, especially on bigger sized spas. A cover concierge is the perfect way to take the pain out of constantly having to struggle with your spa cover. The cover concierge does all the heaving lifting, all you have to do is simply guide the cover back until it is completely off, then when ready guide the cover back into place. Done in seconds!
