They’re cheap and sturdy.
- How much does it cost to make a cinder block bench?
A barebones basic cinder block bench can be built for under $50 USD. The price will go up depending on your choices of cushions, fabric and paint.
The 12 inch blocks run from $2.00 to $4.00 dollars a piece. They drop in price as they drop in size. You may find blocks for free through construction projects.
- How many cinder blocks do you need to make a bench?
The most common design calls for twelve cinder blocks. That’s 6 on each side. You can get away with six blocks in total for a small, low bench.
- How do you stick cinder blocks together?
Construction adhesive or any type of liquid nails will securely hold a few blocks together. Mortar isn’t necessary for any of the following ideas but should be used for bigger projects like retaining walls.
Keep in mind that the strength of cinder blocks is compromised when used with the holes facing outward or on their ends. This is mostly a concern when used as construction or heavy support, but good to know in case you have an ambitious project in your future.
Let’s take a look at these bench ideas.
