Pros and cons

Pros

Two stated flush volumes give buyers a choice between the listed 1.28 GPF full flush and 0.92 GPF light flush.
Multiple wash modes, adjustable spray settings, and a warm-air dryer offer more integrated bidet functions than a basic toilet.
The listed 12-inch rough-in and floor-mounted installation help buyers assess fit before purchase.

Cons

The electronic bidet and automated functions require a nearby power outlet, adding an electrical-location constraint to installation.

What to know before buying

The listing describes the toilet as tankless and the title calls it elongated, but the specifications give a U-shape and do not independently confirm either design detail. The title's 1000g MaP claim is not substantiated elsewhere in the supplied specifications, so confirm the bowl shape, tank design, and MaP rating if they affect your choice. The advertised installation accessories and 12-month replacement-parts service are listing claims. Confirm fit and included installation parts for the selected listing.
