Paint the room a funky, yet cheery color, such as hot pink, turquoise blue or scarlet red, for example. If these colors are too bold for the space, use the selected color on a focal wall and paint the rest of the walls a neutral color.
For example, paint the wall behind the bar scarlet and paint the rest of the walls white or eggshell.
Bring a pre-fabricated, portable bar into the room, or have one built for the space. In addition to a bar, add a high-top table or two to the space.
Add one or two high-top tables into the room.
Set bar stools in front of the bar and around the tables.
Add a small refrigerator/freezer combination behind the bar. Use the unit to store ice and cold drinks.
Bring a velvet or microfiber sofa or settee into the room for additional seating.
Add shelving to the room. Hang shelves on the wall behind the bar in a vertical column or horizontal row.
Lacquered or glass floating shelves add visual interest of the space. Store glasses and wine and liquor bottles.
Remove a chandelier and replace it with glass pendant lights.
Hang metal or glass sconces on the walls to add mood lighting to the space.
Install recessed lighting in the ceiling.
