Hello JAIME ARTURO. This unit does not come with drywall plugs because it should not be installed in that manner for safety reasons. Using drywall plugs would not provide the load bearing capacity needed which could cause the bar to detach while being used. The screws need to be installed in either a stud or if no stud is available, then a Stud-Less Grab Bar Installation Kit such as the WingIts Anchor Kit that is available at Home Depot (Internet # 202552917, Model # RC-RESGBW35-2, Store SKU # 1005557118).
