Hello there,

Thank you for your interest in our products. We are aware that some of our customer's had inconveniences when it comes to making the plumbing of this bathroom vanity. However, under the product description states this is product is European since it is made in Spain. Therefore, not all customer's have this problem, but it depends on the house or apartment's plumbing structure. I included some pictures of the measurements of each part of the vanity and sink front and back. If you have additional questions, do not hesitate to ask us.

Best regards,

Macral Design Corp.
