TOTO Rendezvous Oval Undermount Bathroom Sink

Yes. The Rendezvous oval undermount lavatory is ADA compliant per TOTO's own spec, which is why it shows up in offices, schools, and hotel public restrooms. It mounts under the counter, so the ADA knee clearance and rim height on the finished installation come down to how the counter is set, not the bowl itself.

No faucet holes. The Rendezvous is drilled for no faucet spacing at all, so the faucet is deck mounted through the countertop behind the bowl. Order the faucet and its drilling to the counter fabricator, not to the sink. That also means you are free to run single hole, 4 inch centerset, or 8 inch widespread trim off the same bowl.

LT579G#01 is Cotton White with CEFIONTECT. The G in the model designates the glaze and the number after the hash is the color: #01 Cotton White, #03 Bone, #11 Colonial White, #12 Sedona Beige, #51 Ebony. Drop the G for the same bowl without CEFIONTECT, which is how LT579#51 reads for Ebony.

CEFIONTECT is TOTO's fired-on ceramic glaze that makes the surface harder for waste and soap film to grip, so the bowl needs less scrubbing between cleans. The Rendezvous is sold both with it and without it, in the same five colors either way. For a property manager or MRO buyer standardizing across a building where housekeeping visits are limited, the glazed version is the one to spec; for a single residential bath, the ungazed version is the same bowl.

Oval, with a rimless edge, at 19.25 by 16.25 inches overall. On a shallow vanity the 16.25 inch dimension is the one that usually decides it, since the bowl has to sit clear of both the backsplash and the front edge of the counter with enough material left for the fabricator to carry the cutout. Confirm your counter depth against that number before cutting.

The Rendezvous ships as the vitreous china bowl. Because it has no faucet drilling, plan on ordering the faucet, the deck drilling, a lavatory drain assembly, supply stops and a P-trap separately to finish the rough-in. There is no battery-operated component in the bowl itself, so no sensor power supply is involved unless the faucet you pair with it needs one.

17.4 pounds. That is light enough for one person to hold up while the clips are set, but it is still china hanging off the underside of the counter, so it wants the mounting hardware and adhesive the installation sheet calls for rather than adhesive alone. On stone tops the clip anchors go into the slab, so coordinate with whoever fabricates the counter.
