HYGINA U5 Ultra Smart Toilet with Built-in Tank

HYGINA U5 Ultra combines a toilet and premium smart comfort features in one upgrade, including built-in tank flushing, warm water bidet cleansing, heated seating, automatic lid opening, foot sensor control, foam shield protection, UV hygiene care, remote control, and 256-color ambient lighting.

Yes. HYGINA U5 Ultra combines a concealed built-in water tank with rear, feminine, and moving instant warm water bidet wash modes. For shoppers seeking a smart bidet toilet for low water pressure homes, stored water can reduce dependence on momentary supply pressure for flushing, but the tank still needs adequate pressure and flow to refill.

U5 Ultra includes an adjustable heated seat for cold-weather comfort. The current public product information does not verify an automatic ECO or sleep mode, so do not include projected energy savings in purchase planning unless that function is confirmed in the delivered manual.

U5 Ultra supports automatic lid opening, foot-activated lid and seat-ring control, foot-sensor flushing, and automatic flushing. Nearby traffic, pets, or objects can affect proximity sensing, so keep the sensor area clear and review the current control settings if the lid opens unexpectedly.

U5 Ultra supports rear wash, feminine wash, and moving wash with adjustable water temperature and spray position. Use the delivered manual and remote-control instructions to confirm the available adjustment steps. The public product information does not state the exact number of water-pressure levels.

U5 Ultra is published with self-cleaning nozzle care, UV hygiene care, and deodorizing care. These features supplement routine cleaning. The current public product information does not identify an electrolyzed-water process or a specific active-carbon filter, so confirm the cleaning and consumable details in the delivered manual before assuming either system.

U5 Ultra provides remote-controlled comfort adjustments, but the current public product information does not verify separate multi-user memory profiles. Households that require one-touch saved settings should confirm that function in the current manual before purchase.

Do not treat WaterSense or cUPC as verified U5 Ultra certifications unless the current certificate or specification sheet names this exact model. Certification requirements can affect local code, rebates, and project approval, so request current documentation from HYGINA Support when either credential is required.

Keep the order record, model and serial-label photos, manual, and installation photos. If service is needed, contact HYGINA Support with clear photos or video before opening an assembly. Part availability and repair steps vary by component, so confirm the correct part, warranty status, and qualified service scope first.

Confirm the Standard 12-inch rough-in, measured from the finished wall to the drain center, plus the flange height and condition, drain position, skirted-base and shutoff-valve clearance, water inlet, finished floor, delivery path, and nearby electrical outlet. Use the current U5 Ultra manual as the controlling guide and arrange qualified plumbing or electrical work when changes are needed.

Yes. U5 Ultra is designed for modern bathroom upgrades, master bathrooms, accessible bathroom updates, and premium remodeling projects. Before ordering, review the installation guide and confirm your rough-in, water inlet, drain position, and power outlet.

U5 Ultra requires a nearby 110V / 60Hz GFCI-protected outlet and lists a maximum power of 1350W. The public product page does not specify the operating amperage, branch-circuit size, or cord length. Have a qualified electrician confirm grounding, circuit capacity, receptacle placement, cord reach, splash-zone requirements, and local code; do not plan on an extension cord.

Yes. The concealed built-in tank stores water before each flush, making flushing less dependent on momentary supply pressure than many tankless designs. It still requires enough pressure and flow to refill. Do not rely on a generic 30 psi threshold unless the current U5 Ultra manual specifies it for this exact model and the site has been measured under flowing conditions.

U5 Ultra is designed as an ADA-friendly smart toilet with a built-in water tank, a spacious elongated seat, and a 17.2-inch seat height measured from the finished floor to the top of the seat. ADA suitability also depends on clear floor space, grab-bar planning, and applicable local requirements, so review the product drawing with your installer before purchase.

Do not treat 1000g MaP flushing as a verified U5 Ultra specification unless it appears in a current independent MaP test report for this exact model. U5 Ultra is published with built-in water tank flushing and backup flush support; request the current test documentation if a specific MaP score is required for your project.

Warm-water cleansing and warm-air drying can reduce or sometimes eliminate toilet paper for many users, but drying time and personal preference vary. You can still use a small amount of paper for pat drying or checking cleanliness.

Yes. U5 Ultra is published with a dedicated backup-flush function for basic toilet flushing during a temporary outage. The public product information does not identify whether the backup method uses a battery or a mechanical control, so follow the delivered manual for the exact procedure. Washing, seat heat, warm-air drying, automatic lid, lighting, and other powered features remain unavailable until power returns.

U5 Ultra is published as a smart toilet with a concealed built-in water tank. For shoppers comparing a smart toilet with tank and booster pump, the verified U5 Ultra feature is stored-water flushing; do not assume a separate pump unless it is confirmed in the current product manual or specification sheet. Check actual pressure and flow at the installation site before ordering.
