You can actually find pedestal cabinets, which are essentially vanity cabinets designed specifically to go around pedestal sinks, to hide the unsightly plumbing and provide additional storage. You can also hang a small curtain (they make sink skirts for this) that covers the area. Just make sure that you measure the height and width that you’ll need to go all the way to the floor and around all sides of the sink.
Another option instead of concealing the pipes is to paint them. You can paint them the same color as the walls so that they blend in even when you can’t get them out of sight. You can also choose to paint them an accent color instead so that they become part of the design.
