Measure the floor space you can allow for the bar footprint. Use heavy framing, such as 2-by-6 or 2-by-8 pressure-treated boards to help stabilize the bar. Draw the bar plan as a counter space 42 inches high and 24 inches deep, for example. Figure out the best way to route water lines and drains to the sink and the refrigerator. Connect to water pipes and a drain from a side wall, as one option.
Leave space in the bar base design for a bar refrigerator. Be sure to plan floor framing to support the weight of the refrigerator when it’s installed into the cabinetry. Design a 12-inch counter top overhang for bar stools.
Cut the framing boards with a circular saw to fit a rectangular shape for the base of the bar. Use 4-inch screws to attach the bar bottom plate to floor joists, or use concrete nails or liquid adhesive on a basement floor. Miter all joints and corners as you attach all framing pieces.
Nail ½-inch thick oak plywood over the base. Slide the refrigerator unit into place and cover surrounding edges with wood trim for a built-in look. Install 3/8-inch plywood sheeting inside the cabinet area of the bar as well to construct shelving. Cover the interior plywood with wood veneer sheeting or vinyl laminate glued into place. Add cabinet doors to cover interior shelving.
Select a bar sink and use the sink measurements to cut a bar top. Choose countertop material that harmonizes with the design of your home. Granite tiles are an excellent option for a high-end look. Lay granite tiles with matching grout, allowing for the sink opening and faucet space. Secure the sink into place and hook up the faucet unit. Install a swivel faucet with a high curve made especially for wet bars.
Install fluted pilaster material over corner areas, crown molding at the floor level or a bar rail to dress up the bar. Purchase stools that swivel, so visitors and family members can maneuver easily in the bar space.
