Create Your Dream Outdoor Kitchen with Cinder Blocks: DIY Guide

Ever walked past those bland cinder blocks at the hardware store and thought, “meh”? Well, prepare to see them in a whole new light! An outdoor kitchen built with cinder blocks isn’t just affordable—it’s actually kinda awesome.

Here’s why:

• They’re stupid cheap compared to custom outdoor setups
• Crazy durable against weather, fire, and whatever else nature throws at them
• So easy to work with that even your DIY-challenged friend could handle it
• Totally customizable to whatever size and layout works for your space

Let’s transform that backyard into the outdoor entertaining space you’ve been drooling over on Pinterest. And trust me, your neighbors are gonna be all, “You built that yourself?!”

Why Choose Cinder Blocks for Your Outdoor Kitchen

Cinder blocks are like the unsung heroes of outdoor construction. They’re those reliable friends who never let you down—not glamorous but always there when you need ’em. They cost way less than stone or brick (like, a fraction of the price) while still giving you that solid, built-to-last vibe.

The concrete blocks handle heat from grills and pizza ovens without complaint, and they’re basically weatherproof.

You can leave ’em out in rain, snow, whatever—they don’t care. And seriously, what other building material lets you create an entire outdoor kitchen for under $1,000 if you’re willing to do the work yourself?

Planning Your Cinder Block Outdoor Kitchen

Before you haul home a truckload of blocks, take a sec to figure out what you actually want. Your outdoor kitchen should match how you like to cook and entertain.

Start by answering these questions:

• What appliances do you absolutely need? (Grill, refrigerator, sink?)
• How much counter space will make you happy?
• Do you want seating incorporated into the design?
• What’s your realistic budget? (Be honest with yourself!)
• Where will it be located? (Consider utilities, shade, and views)

Grab some graph paper and sketch it out—nothing fancy, just enough to visualize the space. And don’t forget to check if your neighborhood has any pesky regulations or permits required before you start building.

Essential Materials for Your Cinder Block Kitchen

Let’s talk shopping list. Here’s what you’ll need to gather before breaking ground:

Basic Materials:

• Standard cinder blocks (8″ x 8″ x 16″ is common)
• Concrete mix for foundation
• Mortar mix for joining blocks
• Concrete board for countertops
• Rebar for reinforcement
• Construction adhesive
• Concrete sealer

Tools:

• Shovel and rake
• Level (get a good one—seriously worth it)
• Tape measure
• Trowel
• Rubber mallet
• Circular saw with masonry blade
• Safety gear (gloves, goggles, dust mask)

Pro tip: Buy about 10% more blocks than you think you’ll need. Some might break, and calculating exact quantities is weirdly hard. Plus, returning unused blocks is way less annoying than making a second trip for just a few more.

Laying the Foundation

Your outdoor kitchen is only as solid as what it’s sitting on. A proper foundation isn’t one of those corners you wanna cut.

First, mark your kitchen footprint using stakes and string. Dig down about 6 inches, making sure the ground is level. Then add 2-3 inches of gravel for drainage (trust me, future you will appreciate this step when it rains).

Mix up concrete according to package directions—it should be about the consistency of thick oatmeal. Pour a 3-4 inch slab and smooth it out. Use a level constantly, like obsessively. Let this cure for at least 48 hours before moving on, even if it looks dry earlier.

Building Your Cinder Block Structure

This is where your outdoor kitchen starts taking shape, and it’s actually pretty satisfying work.

1. Lay out your first course of blocks (without mortar) to check your design
2. Mix mortar to a peanut butter-like consistency
3. Apply a 1-inch layer of mortar where your first block will go
4. Set the block and check it’s level both horizontally and vertically
5. Continue with the first course, keeping everything aligned
6. For the second course, offset the blocks to create a staggered pattern
7. Apply mortar between blocks as well as on top of each course

Remember to leave openings for your appliances. Measure those spaces three times—appliances don’t squish to fit!

Creating Spaces for Appliances

Your grill and other appliances need proper support and clearance. Here’s how to make it work:

For built-in grills, create a solid surface with closely spaced blocks or concrete board. Leave at least 3 inches of clearance on all sides of heat-producing appliances—more if the manufacturer recommends it.

For a fridge or ice maker, you’ll need access to electricity, so plan your layout accordingly. Consider installing conduit inside the cinder block walls before closing everything up. It’s way easier now than trying to retrofit later.

If you’re including a sink, remember you’ll need both water supply and drainage. Consult a plumber if you’re not 100% confident with this part.

Designing Your Countertops

Countertops really pull the whole kitchen together. You’ve got options:

Concrete countertops are popular because they:

• Match the industrial vibe of cinder blocks
• Can be colored or stamped for custom looks
• Are incredibly durable for outdoor use
• Cost less than stone options

To create them, build forms with melamine boards, add wire mesh for strength, and pour concrete. Let it cure for several days, then seal it well.

Other options include tile (affordable but joints can be problematic), stone slabs (gorgeous but expensive), or even repurposed materials like old bowling alley wood sealed for outdoor use.

Weather-Proofing Your Outdoor Kitchen

Mother Nature can be mean to outdoor kitchens, so protection is key.

Start by applying a good concrete sealer to all exposed cinder block surfaces. This prevents water absorption and staining. For countertops, use a food-safe sealer that can stand up to sun exposure.

Consider adding a pergola or partial roof over your kitchen area. It’ll extend the life of everything underneath and make cooking more comfortable when the sun is blazing or there’s a light rain.

For areas with freezing winters, install drainage lines that won’t trap water that could freeze and crack your structure. And cover your appliances when not in use—custom covers are worth the investment.

Adding Style to Your Cinder Block Kitchen

Let’s be real—plain cinder blocks aren’t winning any beauty contests. But with a little creativity, your outdoor kitchen can look custom-built rather than like a bunker.

Try these ideas:

• Stucco over the cinder blocks for a smooth finish
• Apply stone veneer to the exterior faces
• Paint blocks in a complementary color (use masonry paint!)
• Install decorative tile on vertical surfaces
• Add wooden accents with cedar or redwood trim

Lighting makes a huge difference too. Consider installing LED strip lights under countertop edges or mounting weather-resistant sconces on the walls. Solar options mean you don’t need to worry about running electricity.

Enhancing Functionality with Smart Additions

An outdoor kitchen should work as good as it looks. These practical additions will make yours more user-friendly:

• Install hooks for hanging utensils and towels
• Add a spice shelf near the cooking area
• Include a pull-out trash bin in your design
• Create a designated drink station with an ice bin
• Build in storage drawers for keeping supplies dry

One of my favorite additions is a simple magnetic strip attached to the wall for holding metal tools. It’s cheap, easy to install, and keeps everything within reach when you’re in grilling mode.

Budget-Friendly Ways to Customize

Building with cinder blocks is already economical, but these ideas stretch your dollars even further:

Repurpose materials when possible. Salvaged sinks, reclaimed wood for shelving, and secondhand appliances can all reduce costs while adding character. Even the cinder blocks themselves can sometimes be found used on marketplace sites.

DIY concrete countertops save hundreds compared to pre-made versions. And instead of buying expensive outdoor kitchen cabinets, create shelving with the same cinder blocks by placing them in useful configurations.

For backsplashes, consider remnant tiles which sell for a fraction of full-price options. Sometimes you can snag them for like 80% off retail price.

Common Mistakes to Avoid

Let’s learn from others who’ve already made these errors:

• Skipping permits – Some localities require permits for permanent structures. Check before building to avoid fines or removal orders.
• Poor spacing – Leaving too little room between cooking areas and seating means guests get smoked out. Allow at least 4 feet of clearance.
• Inadequate lighting – Trying to grill in the dark is how you end up with raw chicken. Install proper task lighting from the start.
• Forgetting about wind direction – Position your cooking area so prevailing winds don’t blow smoke into your house. Your indoor curtains will thank you.
• No drainage plan – Water needs somewhere to go. Slight slopes and drain channels prevent puddles and water damage.

Maintaining Your Cinder Block Outdoor Kitchen

Like anything worthwhile, your outdoor kitchen needs some TLC to stay looking good. Establish these maintenance habits:

1. Reapply concrete sealer annually
2. Check mortar joints for cracks after winter
3. Clean countertops with appropriate cleaners for their material
4. Inspect for any insect activity (they love those little block holes)
5. Flush water lines before first use each season

For deeper cleaning, a pressure washer on low setting works wonders for removing pollen, soot, and general grime. Just keep the pressure low to avoid damaging mortar joints.

These real projects show the versatility of cinder blocks and how different finishing techniques completely transform the final look.

The Finishing Touches

The little details elevate your outdoor kitchen from functional to fabulous:

Add potted herbs nearby for both decoration and fresh cooking ingredients. Install a bottle opener on the side of your structure—it’s both practical and a conversation starter. Consider a small container garden of kitchen herbs built right into the structure.

Comfortable seating invites people to linger. Whether it’s barstools along a countertop edge or a nearby dining table, make sure there’s a place for folks to sit while you’re showing off your outdoor cooking skills.

Your Outdoor Oasis Awaits

So there you have it—building an outdoor kitchen with cinder blocks isn’t rocket science, but it does take some planning and elbow grease. The reward is a custom outdoor cooking space that didn’t require a second mortgage.

Start small if you’re intimidated—even a simple grill surround with counter space can transform your outdoor cooking game. You can always expand later as your confidence (and budget) grows. The best outdoor kitchen is the one you actually build and use, not the perfect one that exists only on your Pinterest board.
