There's more than one way to sell plumbing supplies to consumers. Some retail outlets store hundreds of crated and boxed items in a warehouse environment with a smattering on display for the DIY customer. Some contractors will carry catalogs and brochures in their work trucks so consumers can have a look at what kinds of products are available should a replacement become necessary.
The best way to show customers what kind of plumbing supplies and kitchen and bath dress-up items are available, however, is to set up a showroom-basically a retail space in which various items are displayed to their best selling advantage so consumers can select the items they want you to install.
