TOTO Maris Oval Vessel Bathroom Sink

The Maris oval basin is ADA compliant, so it can be used on an accessible lavatory. The piece it sits in still has to do its part: the counter or carrier has to put the rim at the accessible height and leave the required knee and toe clearance, and the drain and supplies need to be wrapped. The sink itself is not the limiting factor.

No faucet holes are drilled in the Maris basin. The faucet hole spacing is None, so the faucet mounts to the countertop or the wall, not to the sink. Order a single-hole deck faucet and drill the counter, or go with a wall mount spout. Check the spout reach against the basin, which measures 14-1/16 by 18-13/16 inches at the bowl on the 19-1/2 inch wide model, so the water lands near the center of the bowl and not on the rim.

Three sizes are offered, and the cutout follows whichever you order. The LT480 is 15-5/32 by 19-1/2 by 6-7/8 inches, the LT483 is 17 by 20 by 6-9/16 inches, and the LT481 is 17-7/8 by 22-5/8 by 6-5/8 inches. Because it is semi-recessed, the front of the bowl projects past the counter face, so the counter depth matters as much as the cutout. TOTO publishes an installation sheet for the LT480 and LT481 and a spec sheet for all three with the template dimensions.

Both mounting types are offered on the Maris: vessel and undercounter. That is an ordering decision made up front, not something you change on site, so pick the mounting type that matches the counter detail on the drawing before the top gets fabricated.

Yes, and it is at the rear of the basin. That means you can run a standard pop-up drain with overflow ports, and the overflow channel sits behind the bowl where the faucet and supplies are, so it does not interfere with the front projection of the semi-recessed body.

CEFIONTECT is TOTO's glaze option, and the Maris is ordered either with it or without. The G in the model number is the tell: LT480G is the glazed version, LT480 is not. For a public or high-turnover restroom where cleaning labor is the cost, spec the G models. For a residential unit turn where the fixture gets wiped regularly, the standard glaze is the cheaper line item.

Five colors: Cotton White, Colonial White, Bone, Sedona Beige and Ebony. Those are TOTO's standard color codes, so the same finish carries across the toilets and other lavatories in the Maris and broader TOTO line, which is what you want when you are standardizing a building rather than doing a one-off bathroom.

The Maris ships as the china basin. Plan the drain assembly, the trap and the supplies as separate line items, and pick a pop-up with overflow ports to match the rear overflow. No faucet holes are drilled, so the faucet and its mounting hardware are a separate buy as well.

Size drives it. LT480 is the 19-1/2 inch wide model at 15-5/32 deep with a 14-1/16 by 18-13/16 bowl. LT483 is 20 inches wide and 17 deep. LT481 is the largest at 22-5/8 wide, 17-7/8 deep, with a 15-5/8 by 20-3/8 bowl. Add G for the CEFIONTECT glaze and the color code suffix, for example LT481G#01. Height runs 6-9/16 to 6-7/8 inches across the three.

Between 19.3 and 22.6 pounds depending on the model: the LT483 is 19.3, the LT481 is 22, and the LT480 is 22.6. That is a one-person lift, but it is vitreous china with a projecting front, so support the bowl from underneath while the counter cutout and any clips are engaged.
