TOTO Luminist Vessel Bathroom Sink, Frosted White

Both are above counter vessels, so you are cutting a drain pass through, not a rim cutout. Footprint decides the top: the LLT150 round is 15.75 by 15.75 inches with a 14.875 inch basin, and the LLT151 is 12.625 by 19.6875 inches with a 10.8125 by 17.875 inch basin. TOTO's installation sheet gives the template and drain hole location, and a template ships in the carton along with the mounting hardware and chrome drain fitting.

No overflow on the Luminist. A sink without an overflow takes a non-overflow (grid or free-flowing) drain, not the standard pop-up with overflow ports, or the bowl will not drain properly. TOTO includes a chrome drain fitting in the box, so you do not need to source one separately.

The Luminist is listed ADA compliant. Because it is a vessel, the compliance depends on how you set it: the 3-9/16 inch sink height sits on top of the counter, so the counter has to be dropped enough to keep the rim at or below the ADA maximum and leave knee clearance under it. Spec that counter height before you frame the vanity.

The rectangular LLT151 is the narrow-top choice at 12.625 inches front to back by 19.6875 inches, so it suits a shallow vanity but eats counter width. The round LLT150 is 15.75 inches square in footprint, which needs more depth but less overall width. Basin capacity runs the other way: the round holds a 14.875 inch bowl, the rectangle 10.8125 by 17.875.

It is a semi-clear epoxy resin, not glass or china, which is what lets light pass through the bowl. TOTO rates the material scratch and impact resistant. At 12 pounds it is a fraction of the weight of a glass or vitreous china vessel, so the counter loading is light and a single installer can set it.

Two orderable models, both in Frosted White: LLT150#61 is the round bowl and LLT151#61 is the rectangular. The #61 suffix is the Frosted White finish. Each ships with the installation template, mounting hardware and a chrome drain fitting, so the only extras to line up are the faucet and the trap.

It is a vessel sink, designed to sit on a counter or vanity top with the drain passing through. There is no wall-hang prep and no faucet deck on the sink itself. You need a solid top able to carry the 12 pound sink plus water, with the drain hole located to TOTO's template.
