Yes, you can place a kitchen island directly over your existing flooring, but there are some considerations to keep in mind. If you choose to do this, be aware that the weight of the island may dent or affect the flooring over time, especially if it’s a softer material like vinyl or laminate. To avoid potential damage, consider using a mobile island or one with padded wheels, which can be moved aside for cleaning and maintenance without causing harm to the floor.
If you plan to install a fixed island, it's advisable to cut out the flooring underneath the island's footprint. This allows for proper anchoring and can help prevent any issues with spills or moisture getting trapped underneath. Additionally, if plumbing or electrical work is needed for your island, cutting out the flooring will provide easier access for installation. Always ensure that any installation complies with local building codes, especially regarding electrical outlets and plumbing requirements.
