Hello Michael Smith,

We can’t give you a maximum
weight threshold for this cabinet because we don’t have information that
specific, but we can give you some estimates. Based on some of the heavier
configurations this cabinet is sold with (marble countertop, granite sinks,
etc), we can confirm this cabinet can support approximately 180 pounds at minimum.
If you want something heavier than that, we’d recommend you consult with a
contractor or professional first. Please let us know if you have any additional
questions.

Regards,

Modern Bathroom
