# Loniko U5-1-WK Smart Toilet with Built-In Bidet

The Loniko U5-1-WK smart toilet combines a built-in bidet with an automatic lid and flush, heated seat, warm-water wash, and warm-air dryer. Its listed dimensions and floor-mounted design make fit and installation planning important, and the listing says it requires a nearby electrical outlet.

## Before you buy

- The listing says it fits 12-inch rough-ins and advises checking the wall-to-drain center measurement. It also requires a nearby 110V GFCI outlet, so confirm bathroom layout and electrical access before purchase.
- The claimed 1000g MaP score and certification statements are listing claims, not independent verification.
- Listing details conflict or remain unconfirmed: its title and highlights say auto flush, while other copy describes touchless and foot-sensing flush and the technical details call it jet siphon flushing. Power-outage flushing is described both as a mechanical manual flush and as backup-battery-powered, without resolving which applies. The package list names only the toilet, while feature copy claims mounting hardware. Confirm the selected variant and included parts before ordering.

## In the box

- One-piece toilet (Included)

## A good fit for

- Buyers planning a bathroom upgrade who want a toilet with an integrated bidet and powered comfort features.
- Households interested in automatic lid or touchless flush controls and multiple wash settings.
- Installations with a confirmed 12-inch rough-in and suitable nearby GFCI outlet.

## Less suited to

- Bathrooms without a nearby suitable electrical outlet, unless electrical work is planned.
- Buyers who need confirmed package contents, outage-flush behavior, or installation compatibility before selecting a model.

## Customer feedback

The supplied evidence contains aggregate ratings but no written review summary. The overall rating profile is favorable, but ratings alone cannot establish whether buyers liked the bidet modes, automatic functions, installation, or reliability. Treat it as limited satisfaction context rather than evidence of performance.

## Frequently asked questions

### What bidet functions does the Loniko U5-1-WK list?
The listing describes rear, feminine, oscillating, and massage wash modes, adjustable water pressure, instant warm water, and a warm-air dryer.
### What installation requirements should I check?
The listing says the toilet fits a 12-inch rough-in and requires a nearby 110V GFCI outlet. Measure the wall-to-drain center and check outlet access before ordering.
