A sink is just one feature that can be included in a kitchen island, one expert has noted. Contractor and plumber Ed Del Grande, writing for HGTVPro.com, said that some kitchen islands can often have basins already built in.Responding to a readers question as to whether a DIY island would be a good idea, Mr Del Grande stated that a prefab-type option might be the best choice.Basically, theyre ready to go right out of the box - all you need is the plumbing hookups, he replied, adding that while they may be more expensive, the labour costs should be drastically reduced. For complicated electrical work and pipe jobs it may be better to call out a professional, the specialist explained. Last month, interior design specialist Anita Parker commented that a new kitchen island can often brighten up cooking areas, as well as providing additional space for entertaining or eating.
