Immerse yourself in uncompromising luxury with the Millennium 9, an impressive 77" x 77" hydrotherapy bathtub designed to deliver world-class spa indulgence within your own home. Expansive in scale and beautifully sculpted, this premium acrylic drop-in tub transforms your bathroom into a private sanctuary dedicated to deep relaxation, renewal, and elevated wellbeing.

Purpose-built as a dual hydrotherapy bath, the Millennium 9 features two independent bathing zones that allow each bather to enjoy a fully personalized experience. Raised seating, sculpted armrests, and molded footrests create an ergonomic interior that supports the body in total comfort, while two extra-soft magnetic comfort pillows gently cradle the neck and shoulders for extended, effortless soaking. A slip-resistant textured floor enhances safety, and an adjustable metal base ensures a stable, precision installation that complements the tub’s bold, refined design.

At the core of the Millennium 9 is an advanced hydrotherapy system featuring 24 expertly positioned jets that combine powerful whirlpool massage with the soothing lift of air therapy. Independent whirlpool and air systems allow each element to operate separately or together, delivering a fully customizable spa experience. Targeted jets stimulate circulation, relieve muscle tension, and provide deep physical restoration, while independent pumps for each bathing zone ensure consistent, high-performance massage for both users. Dual electronic controls make personalization effortless, placing complete control at your fingertips.

The air massage system adds a calming, sensory layer to every soak. In-floor illusion air injectors release thousands of gentle, effervescent bubbles that create a weightless, enveloping sensation, while a variable-speed heated-air blower with wave and pulse modes allows you to tailor the rhythm and intensity of your relaxation. A purge and dry cycle maintains system cleanliness, and a 1.5 kW inline maintenance heater helps preserve optimal water temperature for longer, uninterrupted moments of peace.

To complete the experience, three high-intensity LED chromatherapy lights illuminate the bath in soothing hues that promote emotional balance and mental clarity. A floating remote control keeps every function conveniently within reach, allowing you to remain fully immersed in the moment without disruption. Crafted from premium cast acrylic, the Millennium 9 offers a luminous, high-gloss finish that retains heat beautifully while delivering exceptional durability.

Indulgent, immersive, and meticulously engineered, the Millennium 9 is more than a bathtub—it is a personal wellness destination. Designed to restore the body, quiet the mind, and elevate daily rituals, it delivers a spa-caliber experience so luxurious it becomes an essential part of how you relax, recover, and reconnect.

Installation

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.

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.

Shop now

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).
