Everyday Comfort You Can Feel
The Dartmouth’s generously sized oval bowl supports comfortable handwashing and daily routines, while the hidden overflow preserves a clean, uncluttered look from the user’s view.
Durable Materials, Easier Care
High-gloss vitreous china resists staining and routine wear, so the basin stays bright with simple, non-abrasive cleaning—ideal for busy family baths and guest spaces.
Installer-Friendly Undermount
Arrives with a paper template and hardware to speed layout and drilling. For granite or marble, follow TOTO’s instructions and use the recommended sealing kit for a lasting bond and seal.
Sized Right For Modern Vanities
The undermount design frees up deck space and fits common vanity sizes; verify cabinet clearances for the trap and a standard 1-1/4″ drain assembly.
Accessible When Mounted Correctly

Warm, Versatile Finish
