The cost to build a commercial bar is going to vary greatly depending on the size and complexity of your project.
It can be difficult to predict the total cost of building a commercial bar, because there are many factors that affect the final price tag. The main factor is how much time you have to dedicate to building it, but other considerations include:
The size of your bar – If you need a large bar that will seat many customers at once, then it will take more time and materials than if you only need a small one that seats ten people at most.
The shape of your bar – A curved or rounded bar will cost more than a straight one because it requires more work to install properly.
The type of wood used – Some woods are more expensive than others and may require special treatment before they can be used for construction purposes.
Cost to build a commercial bar
The cost to build a bar varies, but it is possible to build a home bar on a budget. In fact, you can build your own bar and save money while doing so.
The following are some tips for building your own home bar:
Use reclaimed lumber. Reclaimed lumber is cheaper than new wood and it will give your bar a unique look.
Use salvaged furniture pieces. Salvaged furniture can be found online or at flea markets and garage sales. You can even find them at antique stores and second-hand shops. This is another way to save money on your bar project because you’ll be using materials that are already in good condition instead of buying new ones that will need to be replaced later on anyway.
Ask friends or family members if they have any old appliances that they’re willing to give away or sell at low prices (this includes appliances like refrigerators, dishwashers, etc.). These appliances can come in handy when building your own home bar because they can be repurposed into cool features like shelves or cabinets for storing items such as alcohol bottles, glasses and food items used for serving drinks at parties hosted at your home bar (example: vegetables used for garnishing drinks). 
how much does it cost to build a restaurant
The cost to build a restaurant depends on the size of the space and its features. According to the National Restaurant Association, the average cost to open a new restaurant is $1 million, with most new restaurants spending between $500,000 and $750,000.
If you’re looking for a less expensive alternative to opening your own restaurant, consider starting out with a food truck. Food trucks are often cheaper than building a brick-and-mortar location because they don’t require as much capital outlay.
You’ll also have to factor in costs such as labor and equipment if you plan on building from scratch rather than purchasing an existing building or converting an existing structure into a restaurant.
Here’s how much it costs to build a bar on a budget:
A small-scale home bar — such as one that might be built in a basement or garage — doesn’t require much investment but does take some work and planning. Materials for the project may cost anywhere from $100 to $300 depending on how elaborate you want your bar to be. The following tools will help you get started:
Hammer
Table saw (optional)
Drill/driver combo kit
Circular saw (optional)
