Installation

Before You Start

Confirm the basic bathroom requirements before installation to reduce fit issues, connection problems, and unnecessary returns.

  • HYGINA smart toilet bathroom fit icon for checking drain position, space, and installation requirements

    Bathroom Fit & Rough-In

    Confirm the Standard 12-inch rough-in, drain center, flange height and condition, skirted-base clearance, shutoff-valve position, and available space. A raised, damaged, or offset flange or a valve inside the skirt area can require plumbing changes.

  • HYGINA smart toilet power and water icon for checking outlet and inlet angle valve readiness

    Power & Water Connection

    Confirm a nearby 110V / 60Hz GFCI-protected outlet, listed maximum power of 1350W, and a compatible water inlet angle valve. The public product information does not state cord length or final circuit sizing, so a qualified electrician should confirm placement, grounding, capacity, splash-zone requirements, and code compliance.

    Tools & Accessories

    Prepare the required tools, sealing materials, water hose, and installation accessories before starting the installation process.

    Two-Person Handling Recommended

    Smart toilets are heavy ceramic products. Two-person handling is recommended for safer lifting, positioning, alignment, and final placement.

Installation FAQs

Which installation guide should I use?

Use the HYGINA U5 Ultra Installation Guide for your U5 Ultra smart toilet. Review the bathroom fit checklist, connection notes, step-by-step setup flow, and final function testing before installation.

Can I install a HYGINA smart toilet by myself?

Some homeowners may be able to complete the installation, but professional installation is recommended if plumbing, electrical work, lifting, alignment, internal reconnection, or bathroom fit confirmation is required.

What should I check before installation?

Confirm the Standard 12-inch rough-in, drain center, flange height and condition, skirted-base and shutoff-valve clearance, nearby 110V / 60Hz GFCI-protected outlet, water inlet angle valve, finished floor, delivery path, and two-person handling plan.

What If the Existing Flange or Shutoff Valve Conflicts with the Skirted Base?

Do not force the toilet into position. Have a qualified plumber check flange height, damage, offset, drain alignment, finished-floor condition, and shutoff-valve clearance against the current U5 Ultra drawing. Flange repair, relocation, or valve changes should be completed before final placement and sealing.

Why Can Adding a GFCI Outlet Change the Installation Cost?

Older bathrooms may need a new receptacle, circuit extension, grounding correction, or code-required placement work. Cost varies by panel capacity, wire route, wall access, permits, and local labor. Request an itemized quote from a qualified electrician before ordering; HYGINA does not set local electrical labor rates.

What if my actual unit or accessories look slightly different from the images?

Minor hardware, accessory, or internal layout differences may occur due to production updates. Always follow the delivered product configuration and contact HYGINA Support if anything is unclear before continuing installation.

Do I need to test the functions after installation?

Yes. After installation, turn on the water supply and power, then test flushing, washing, drying, heated seat, remote control, side knob, foot sensor control, automatic lid operation, foam shield, UV hygiene care, and other U5 Ultra functions before daily use.
