Plumbing is a major concern in every bathroom remodel. Many homeowners that choose to remodel a bathroom decide to keep the location of the current plumbing since moving plumbing can be both costly and time consuming. If they have decided to add other fixtures or accessories around where the former vanity cabinet space had been, then an offset sink vanity can be just the solution. If this is the reason for your purchase, then it�s always a good idea to request a spec sheet before ordering to make certain that it will fit your plumbing requirements.
