Details

Transform your bathroom into an extraordinary spa sanctuary with the Millennium 8, a breathtaking 72" x 72" corner hydrotherapy bathtub created for those who expect uncompromising luxury, comfort, and performance. With its expansive footprint and sculpted interior, the Millennium 8 commands attention as a dramatic centerpiece while delivering a deeply restorative bathing experience inspired by the world’s most exclusive wellness retreats.

Expertly crafted from premium cast acrylic with a luminous high-gloss finish, the Millennium 8 blends contemporary sophistication with enduring durability. Its corner configuration maximizes space without sacrificing comfort, making it an ideal choice for creating a refined, spa-inspired atmosphere in a master bathroom. Raised seating, sculpted armrests, and molded footrests are ergonomically designed to support the body in total relaxation, while two extra-soft magnetic comfort pillows gently cradle the neck and shoulders for extended, effortless soaks. A slip-resistant textured floor enhances safety, and an adjustable metal base ensures a stable, precise installation worthy of its luxury design.

Purpose-built as a dual hydrotherapy bath, the Millennium 8 features two independent bathing zones, allowing each bather to enjoy a fully personalized experience. Dual electronic controls provide effortless customization, while independent pumps for each zone deliver powerful, uninterrupted performance. An advanced system of 24 hydrotherapy jets surrounds the body with revitalizing massage, easing muscle tension, stimulating circulation, and promoting deep physical relief.

The experience is elevated further through a sophisticated air massage system that introduces a lighter, calming dimension to your soak. In-floor illusion air injectors release thousands of gentle, effervescent bubbles, creating a weightless sensation that soothes both body and mind. A variable-speed heated-air blower with wave and pulse modes allows you to tailor the rhythm and intensity of your massage, while a purge and dry cycle keeps the system clean and comfortable. A 1.5 kW inline maintenance heater helps maintain the ideal water temperature, extending your relaxation without interruption.

Three high-intensity LED chromatherapy lights bathe the water in calming hues that enhance emotional balance and mental clarity, completing the multisensory spa experience. A floating remote control keeps every function conveniently within reach, allowing you to remain fully immersed in the moment.

Luxury, innovation, and therapeutic excellence converge in the Millennium 8. More than a bathtub, it is a private wellness retreat—beautifully designed to help you release stress, restore your body, and reconnect with peace, all from the comfort of home.

Care & Maintenance

Aquatic uses durable, high quality materials and innovative technology in the manufacturing and design of its products to reduce the time you need to spend cleaning and caring for them.  However, proper and regular maintenance is still vital.

Follow these general use and maintenance tips, as well as any that come with your Aquatic Bath product, and you will be rewarded with many years of great service.

General Purpose Cleaning

  • For best results use Aquatic CLEAN
  • Any nonabrasive liquid cleaner off the shelf may be used.
  • Be sure to read the label and follow the cleanser’s recommendations.
  • Do not use harsh abrasives as they will harm and dull the finish of your unit.
  • Instead, use warm water and liquid detergents, especially those bathroom cleaners recommended for cleaning fiberglass, such as
    • Top Job All-Purpose
    • Mr. Clean All-Purpose
    • Boraxo Bathroom
    • Lysol Bathroom
    • Liquid Spic & Span
    • ...and similar products.

For most stubborn stains on your anti-skid floor

  • Make a paste of a cleanser such as Comet, Spic-N-Span, etc., and spread out onto the floor.
  • Allow the paste to sit for 5-10 minutes and then gently scrub with a soft-bristled brush.
  • To prevent scratches, the brush should be no rougher than the texture of a toothbrush.

For hard water stains, calcium deposits, lime scale or difficult soap

  • After repeated attempts with the suggestions above, you may try Lime-Away or white vinegar for removal of calcium or lime deposits.
  • For soap scum, general black grime or algae, diluted household bleach may be used with moderate scrubbing.
  • In both instances, the unit should be rinsed carefully with cold water.
  • Scrubbing is never recommended as it could damage the finish on your floor.
  • Always rinse off all remaining paste.
  • If you use a rubber or plastic anti-skid mat, make sure to remove it after every shower to avoid harming the surface finish.

Customizable Therapy for the Best of Both Worlds

The combination system marries the immersive stimulation of the air bath with the targeted massage of the whirlpool. The systems can be used individually, or simultaneously for maximum impact.

Whirlpool Massage Therapy

Targeted and powerful. The force of water works with the heat of the back to release your muscle tension and treat your trouble spots like the neck, back, hips, and knees. 

Air Bath Therapy

Air is pushed into the bath water thru pin-sized portals, forming a blanket of bubbles that dance and swirl from head to toe, creating a gently exhilarating experience.

Air-Whirlpool Combination Baths

Deliver a truly luxurious spa experience in the comfort of your own space. Powerful shiatsu jets melt away tension along your back while thousands of effervescent air bubbles envelop your body in soothing relaxation. Designed to recreate the feel of a high-end wellness retreat, these premium baths transform any bathroom into a serene sanctuary of comfort, rejuvenation, and indulgence.

Shiatzu Back-Massage System

Rooted in ancient Japanese healing practices, shiatsu is a time-honored finger-pressure technique known for promoting circulation, easing stress, and relieving discomfort. Drawing inspiration from this traditional therapy, the Millennium bathtub back-jet system was engineered using decades of expertise in advanced whirlpool technology. With a precise combination of 4 rotary jets and 8 directional jets, it delivers a deeply soothing hydrotherapy experience that both rejuvenates the body and calms the mind.

đź«§đź’§What Are Hydrotherapy Tubs?đź«§đź’§

Hydrotherapy tubs—also known as therapeutic soaking tubs, whirlpool tubs, or spa tubs—are specialized bathtubs designed to use water, heat, and targeted massage to promote relaxation, pain relief, and overall wellness.

Air-Jet Tubs

  • Use many small jets that push heated air into the water, producing thousands of tiny bubbles that gently caress your body.

  • Massage sensation is gentle, soft, full-body rather than deep or intense.

  • Tend to be quieter, lower maintenance, and less risk of mold or mildew buildup (because they don’t recirculate bathwater internally).

→ Best for: everyday relaxation, stress reduction, gentle circulation boost, skincare, sensitive joints — or if you want a more “soothing spa soak” rather than intense massage.

Shop now

Whirlpool Tubs

  • Use large water jets that push water strongly — giving a deep, targeted hydro-massage to muscles, joints, back, legs, etc.

  • Great if you want therapeutic benefits: muscle soreness relief, improved circulation, joint pain relief, post-workout recovery, arthritis relief, etc.

  • Downside: usually noisier, more maintenance (need to clean internal pipes/jets) to avoid mold or buildup.

→ Best for: those dealing with chronic muscle/joint pain, requiring deep tissue massage, or seeking real therapeutic hydrotherapy rather than just relaxation.

Shop now

Combination Tubs (Air + Whirlpool Jets)

  • Combine both air-jets and water-jets: you get the gentle bubble therapy and powerful water massage depending on setting.

  • Offer versatility— you can pick gentle bubble mode for relaxation or switch to water jets for deep muscle therapy.

→ Best for: people who want both occasional deep massage and frequent gentle soaks — good if you’re not sure which you’ll use more, or if your needs change (e.g. sometimes stress relief, sometimes muscle recovery).
