U5 Ultra includes built-in tank flushing, automatic lid opening, foot sensor control, warm water bidet cleansing, heated seat, warm air drying, foam shield protection, UV hygiene care, remote control, side knob control, an ADA-friendly 17.2-inch seat height measured from the finished floor to the top of the seat, and 256-color ambient lighting.

Yes. U5 Ultra is designed with automatic lid opening for a more hands-free bathroom experience. Foot sensor control also supports easier daily operation when your hands are occupied.

The foam shield helps cover the bowl surface with a protective foam layer to reduce splash, help control odor, and support a cleaner bathroom experience during daily use.

UV hygiene care adds hygiene support for selected internal areas. It is designed as an added cleanliness feature alongside regular cleaning and normal care.

Choose U5 Ultra if you want a premium smart toilet upgrade with reliable flushing support, hands-free convenience, warm water cleansing, heated comfort, hygiene-focused features, remote control, and a more refined bathroom experience.

Yes. HYGINA U5 Ultra uses a concealed built-in water tank that stores water before each flush, helping support more consistent performance where household pressure is lower or variable. Low water pressure compatibility still depends on enough pressure and flow to refill the reservoir, so verify the supply line and shutoff valve before installation.

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 current public product information does not state the exact number of water-pressure levels.

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 assume a specific energy-saving schedule or projected savings unless that function is confirmed in the delivered manual.

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

U5 Ultra provides remote-controlled comfort adjustments, but the current public product information does not verify separate multi-user memory profiles. If one-touch saved settings for different family members are essential, confirm that function in the current manual before purchase.

Do not treat WaterSense or cUPC as verified U5 Ultra certifications unless a current certificate or specification sheet names this exact model. These credentials can affect code approval, state requirements, or rebate eligibility, so request current documentation from HYGINA Support when either certification is required.

Confirm the GFCI outlet has power, check the remote battery if it is user-replaceable, remove obvious signal obstructions, and follow only the pairing or reset procedure in the delivered manual. Repeated unplugging should not be treated as a normal repair. For recurring control loss, error codes, unexpected flushing, leaks, or overheating, stop use as appropriate and contact HYGINA Support with photos or video.

Before a long absence, follow the delivered manual for water, power, cleaning, storage, and freeze-protection steps. When returning, inspect the unit, restore utilities as instructed, allow the built-in tank to refill, test several flushes and powered functions, and clean the bowl and nozzle area. Contact support if odor, leakage, restricted flow, or unusual operation persists.

Yes. U5 Ultra includes a documented backup flush for toilet flushing during a power outage. Powered washing, heated-seat, warm-air-dryer, automatic-lid, lighting, and other electronic functions remain unavailable until power returns. Follow the delivered manual for the exact backup procedure.

Warm-water washing and warm-air drying can reduce and sometimes eliminate toilet paper use, but preferences and drying time vary. Toilet paper remains optional for users who prefer it.

Use the self-cleaning or nozzle-cleaning steps in the delivered U5 Ultra manual, follow its shutdown precautions, and clean only with approved materials. Do not pull, force, or disassemble the nozzle, and do not use an unapproved cleaning method.

Hard water can leave mineral deposits in the nozzle and other water-contact areas, reducing or redirecting flow. Follow the delivered U5 Ultra manual for approved cleaning and maintenance intervals; do not use acids, descalers, or chemicals unless the manual permits them. Ask a qualified plumber to evaluate persistent scaling, restricted flow, or local water-treatment needs.

Nearby traffic, pets, objects, or a dirty sensor area can cause unwanted proximity detection. Keep the sensor area clean and unobstructed, remove nearby triggers, and review the current control settings in the delivered manual. If repeated opening continues, contact HYGINA Support with a short video rather than opening or modifying the sensor assembly.

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

A built-in tank stores water for the flush, making performance less dependent on momentary supply pressure than many tankless designs. It still needs sufficient water pressure and flow to refill, and it cannot correct a blocked drain, failed shutoff valve, or zero water supply.

Cost varies by location and site readiness. Request an itemized quote covering old-toilet removal, flange and drain condition, water connection, the 110V / 60Hz GFCI outlet, fixture placement, function testing, permits, and disposal. HYGINA does not set local labor rates.

Ask a licensed local plumber to review the installation drawing, manual, rough-in, drain, water inlet, outlet, clearances, and site photos before scheduling. Use a qualified electrician when outlet or circuit work is required. HYGINA Support can provide product documents, while you should verify local licensing, insurance, scope, and code requirements.
