The sink is 16"x6". The thickness is approximately 1" so the depth of the inner bowl is 5". Here is an excerpt from our care instructions:

Clean your
natural stone sink regularly with neutral and non-abrasive cleaners.
Calcareous stone (calcium carbonate) is sensitive to acidic cleaners so avoid
cleaning solutions that are highly acidic (lemon, vinegar, etc.). Rinse
completely after applying a cleaning product to avoid leaving film or soap
scum. Don't allow standing water to accumulate on the stone as this may
leave a film or watermark. Remove soap scum from natural stone by
using a mix of 1/2 cup of ammonia with a gallon of water. Natural stone sinks
are porous and has the potential to stain. Some of the most common
culprits are red wine, fruit juices, coffee, rust, ink, paint, soap
scum and water spots. Blot stains with a paper towel. Avoid
wiping the stain as it may cause it to spread.

Sealing
your natural stone sink

We
recommend that you seal your natural stone sink to prevent staining. The stone should be sealed
once a year unless you are using a longer term sealer. Sealers do not
prevent stains completely, so the caring instructions above should be followed.
