Bugs similar in shape and appearance to roaches could very well be roaches. Different roach breeds come in different sizes and many times are found together in infestations.
I am not sure of the proper name but I do know they are from the betetle family and once you get them I don't know of anyone that can get rid of them without and exterminatoer but they are not a roach.
They could possibly be earwigs. Earwigs gather in moist dark area's like tubs and sinks. Some people often confuse box Elder bugs with roaches too. Box Elder bugs are black with an orange color on their wings.
