This is an antique cast iron enamel bathroom sink.
The backsplash measures about 10 1/2 inches tall by about 19 1/2 inches wide
The sink measures about 17 inches deep (distance from wall to edge of sink) by about 19 1/2 inches wide
The sink basin is about 6 1/2 inches deep
The sink front measures about 4 1/2 inches wide.
This would be great for a vintage retro project.
