For a professional plumbing contractor the supply house is the last place you want to take a homeowner in the middle of a kitchen or bathroom remodel. Yes, the supply house has a wide assortment of faucets, showerheads, bathtubs, etc., but it’s all in packaging. None of it looks the way you know it will when it’s installed. Your clients have nothing to go by but the picture on the side of the box. And it’s all grouped by brands or product codes making it difficult to comparison shop.
