This Architectural Drawing is AutoCAD 2d drawing of jacuzzi and bathtub design cad blocks in AutoCAD, dwg file. In reality, there is nothing to distinguish one from the other. They're all large containers of hot water that have jets, bubbles and often different coloured lights and other accessories. Whirlpool bath, Jacuzzi and hot tub are, on the whole, different words to describe the same thing.
