TOTO Dartmouth Bathroom Sink, Cotton White

Yes. The Dartmouth pedestal sink is sold in a 4 inch center drilling as model LPT642.4#01, which takes a standard centerset faucet with 4 inch center-to-center handle spacing. If your faucet is a widespread with 8 inch centers, order LPT642.8#01 instead, and for a single-hole faucet order LPT642#01. The drilling is fixed at the factory, so pick the deck drilling that matches the faucet you already have.

Plan for a footprint of 18.25 x 24.25 x 36.25 inches on the LPT642 pedestal combination. That height is TOTO's Universal Height, so the rim lands higher than an older standard pedestal, which is worth checking against an existing mirror or backsplash tile line before you demo. The unit weighs 44 pounds assembled, so it is a two-person set for most crews.

It ships as a two-piece combination and both pieces are covered under the one model number. The LPT642.4#01 is made up of basin LT642.4#01 and pedestal PT642#01. You are not sourcing the leg separately.

Yes. LT641#01 and LT643#01 are basin-only models in the Dartmouth line, drilled without faucet holes. LT641 measures 16.25 x 21.25 x 7.25 inches with a 13.75 x 18.75 inch basin and weighs 21 pounds; LT643 measures 14.875 x 19.25 x 6.625 inches with a 12.875 x 17.25 inch basin at 17 pounds. Those are the ones to spec when you are dropping into a vanity or a countertop rather than standing on a pedestal leg.

There is an overflow and it sits at the rear of the basin. That matters when you pick the drain: a rear overflow means you need a grid or pop-up assembly with overflow ports, not a solid non-overflow drain. Ordering a non-overflow drain for this basin blocks the overflow channel.

The usable basin on the LPT642 pedestal models runs 11.25 by 16 inches, set in a 18.25 by 24.25 inch top. The extra deck area goes to the large backsplash and the front rim, so you get a deep basin without giving up the ledge people set soap and a toothbrush glass on. If you need a wider bowl in the same collection, the LT643 basin measures 12.875 x 17.25 and the LT641 measures 13.75 x 18.75.

It fits the profile. The Dartmouth is a rectangular pedestal lavatory in Cotton White, TOTO's standard white that matches across their toilet lines, so you can standardize a whole floor of units on one color. The Universal Height rim suits mixed adult occupancy, and because the pedestal hides the trap you avoid the exposed supply and P-trap you get with a wall hung bowl. The trade-off for a property manager is storage: a pedestal gives you none, so where tenants need under-sink cabinet space a vanity-mounted basin like the LT643 is the better call.

Four drillings are offered across the Dartmouth line: single hole, 4 inch center, 8 inch center, and undrilled. Basin widths run 16, 17.25, and 18.75 inches. Every piece is Cotton White. The confirmed model numbers are LPT642#01 (single hole, 16 inch), LPT642.4#01 (4 inch center, 16 inch), LPT642.8#01 (8 inch center, 16 inch), LT641#01 (undrilled, 18.75 inch) and LT643#01 (undrilled, 17.25 inch).

At 36.25 inches overall it stands at TOTO's Universal Height, which puts the rim closer to a kitchen-counter height than the roughly 31 to 34 inch rim on older pedestal lavs. If you are swapping one out in an existing bath, re-check the mirror height and the supply stub locations before you set it, since the taller body changes where the trap arm meets the wall.
