We used this 1000mm dark grey vanity WC unit back to wall toilet where space is tight, and it fitted the plan much better than separate units. With this 1000mm dark grey WC set, the panels have a consistent finish, so the vanity and WC section look matched. The back to wall setup helped make our toilet area feel less cluttered. The set looks better in place than it did while still in the boxes. It is a good option for a tidy toilet and basin area where you do not want to match separate pieces.
