TOTO Oval Wall-Mount Bathroom Sink with CEFIONTECT

No. The LT650G is drilled single hole only, so it takes a single-hole faucet. A widespread (three-hole, 8 inch spread) or a centerset 4 inch trim will not mount on it. If the spec calls for 4 inch centerset or widespread trim, you need a different lavatory drilling, not an adapter plate on this bowl.

There is no overflow on the LT650G. That decides the drain: a no-overflow lavatory needs a grid drain or a pop-up made for sinks without an overflow (no side ports on the drain body). Fitting a standard overflow-type pop-up here leaves an open port under the bowl and it will weep. Order the drain to match.

27.5 pounds of vitreous china hanging off the wall, plus water and whatever gets leaned on it. That means solid backing, not drywall anchors. In wood framing put in a 2x block or a full backer between the studs at the hanger height; in metal stud or masonry, a proper wall carrier or through-bolted backing. Set the blocking before the board goes up, because the mounting height is fixed once the sink is hung.

CEFIONTECT is TOTO's ceramic glaze, fired into the surface rather than applied as a coating. It keeps waste and residue from grabbing onto the china, so the bowl stays cleaner between cleanings. For a property manager or a housekeeping crew running a lot of restrooms, that is the practical difference: fewer scrub cycles on the bowl. It is part of the glaze, so there is nothing to reapply.

Two colors: Cotton White (LT650G#01) and Sedona Beige (LT650G#12). Those #01 and #12 suffixes are TOTO's standard color codes across their china, so if the toilets already in the building are #01, the sink in #01 is the same color family. Check the suffix on the existing fixture and order to match rather than eyeballing white against white.

Go wall-mount when floor space or under-sink access is the constraint. The LT650G hangs on the wall at 29.5 inches wide with nothing touching the floor, so mops go straight under it and a wheelchair can pull up. The trade-off is twofold: the P-trap and supplies are exposed unless you add a trap cover, and the wall has to be blocked to carry 27.5 pounds plus load. A pedestal hides the trap and carries part of the weight to the floor; a vanity gives you storage. If nobody is going to open the wall for blocking, a pedestal or vanity is the easier retrofit.

The sink itself is the china. Budget separately for the single-hole faucet, a drain suited to a no-overflow bowl, a P-trap with supplies and stops, and the wall blocking or carrier. In a public or ADA restroom add insulation wrap on the trap and hot supply. Nothing in that list ships as part of the bowl.

TOTO publishes three documents for the LT650G that carry the rough-in: the spec sheet at https://zensupply.com/content/pdf/toto/gv92pvtm4irkojmsb5mf.pdf, the installation sheet at https://zensupply.com/content/pdf/toto/l6nbftbtiruqgrnbny4f.pdf, and the parts manual at https://zensupply.com/content/pdf/toto/bxgfumyc36wpqx6wmjyo.pdf. Pull the spec sheet before the plumber sets the stub-outs, since the hanger height fixes the rim and everything else follows from it.
