Wrap the pipes with a decorative, colorful material for a low-budget pipe-hiding option. Cover the pipes with decorative fabric, fake plants or vines or thick pieces of ribbon. Attach a big bow to any valves for coverage.
Install faux exposed beams over the pipes for a big-budget project that can add anything from a rustic to high-class appeal to the room, depending on the style. These types of beams have the appearance of solid ones, but they come in the shape of a "U" with a hollow mid-section that goes over the pipes.
Create a fabric-draped ceiling for a low-budget pipe-hiding project that can add texture and color to the room's upper section. Measure the ceiling area and obtain a fabric piece that will cover the area, accounting for the hanging pipes. Attach the fabric to the ceiling using a staple gun. Cover the area just around the pipes as an alternative.
Remodel the area by building a soffit that extends far enough to hide the exposed pipes from view. Soffits are extensions of the ceiling. Use 2-by-2 boards to create a frame around the pipes and cover the frame with drywall. Paint the soffit the same color as the ceiling.
