Why Choose a Concrete Bird Bath?
Out of all the materials suitable for birdbath construction, I always recommend concrete for its durability, customizability and aesthetic appeal. Here are the top reasons concrete makes an excellent birdbath material:
-
Long-lasting durability – Properly constructed concrete birdbaths can last 5-10 years or longer. The American Concrete Institute finds that concrete bird baths have an average lifecycle of over 15 years when properly maintained and sealed annually.
-
Withstands weathering – Concrete is highly resilient against the elements. Concrete bird baths can remain outside year-round through freezing winters, hot summers and everything in between.
-
Endless design options – You can sculpt, texture and paint concrete in unlimited ways for one-of-a-kind style. I‘ll share some of my favorite looks later on!
-
Thermal mass regulates temp – The dense mass of concrete moderates water temperature. According to avian veterinarians, this helps keep bath water between 60-85°F, ideal for comfortable bird bathing.
-
Easy to customize shape– Pour concrete into any mold or form to create literally any birdbath bowl shape you can dream up!
-
Cost effective – Basic concrete ingredients are inexpensive. Concrete mixes start at around $4 per 80 lb. bag.
Concrete checks all the boxes – long-lasting, weather-resistant, customizable, thermally stable and budget friendly. That‘s why it earns my recommendation as the best DIY bird bath material.
Bird Bath Bowl Dimension Recommendations
When crafting your concrete birdbath, I recommend following these dimensions for an ideally sized bowl:
-
Diameter: 12-18 inches wide. This provides ample room for birds to splash around and bathe comfortably.
-
Depth: 3-5 inches deep. This depth gives birds enough water to immerse themselves without being too deep.
-
Wall thickness: At least 1 inch thick. This ensures adequate strength and insulation to maintain water temperature.
Birdbath bowls smaller than 12 inches or shallower than 3 inches will be too cramped for birds to bathe properly. Larger than 18 inches or deeper than 5 inches can be difficult for birds to use safely.
I‘d suggest using a medium-large mixing bowl, basin or planter around 16 inches wide and 4 inches deep to achieve the perfect birdbath bowl size for welcoming a variety of wild birds to bathe.
Choosing the Perfect Concrete Bird Bath Mold
In my experience, the mold you choose makes all the difference in achieving your dream birdbath design. I‘m going to share my top mold recommendations so you can find the perfect vessel to craft your concrete bowl:
Plastic Bowls
Medium to large plastic mixing bowls, buckets or basins make wonderfully convenient concrete molds. Look for these mold benefits:
- Smooth, nonporous plastic unmolds easily from cured concrete.
- Molded rims can add built-in decorative detailing.
- Bowls are readily available at any big box store.
- Choose lightweight bowls for easy handling while pouring concrete.
Make sure to thoroughly clean and dry any plastic mold before pouring concrete into it. Lightly coat the inside with nonstick cooking spray so your finished birdbath releases easily.
Planters or Pots
For an earthy, organically shaped birdbath, I love to upcycle old ceramic or concrete planters and pots as molds. Seek out pots that:
- Range from 12-18 inches wide and at least 5 inches deep
- Have a simple, pleasing shape with no heavy ornamentation
- Are free from cracks or holes
You can use both glazed and unglazed planters. If the planter has drainage holes in the bottom, seal these up with caulking or weatherproof tape before pouring in concrete.
Sandcastle Molds
For a fun birdbath project with kids, pick up a plastic sandcastle mold or sandbox mold from a toy store or discount retailer. Look for:
- Sculpted designs like seashells, starfish and turtles
- Deep enough to hold 3-4 inches of concrete
- Fun shapes to delight both kids and birds!
Plastic castle molds quickly release concrete after curing, revealing all the beautiful detailing. It‘s an easy way to add playful ornamentation.
Make Your Own Custom Mold
If you can dream it, you can mold it! For total creative freedom, build your own custom birdbath mold from:
- Wood – Craft a mold from plywood, lumber or even an old wooden barrel.
- Cardboard – Layer cardboard to create unique shapes and textures.
- Inflatables – Blow up a beach ball or kid‘s pool floatie to epic proportions for a spherical birdbath.
When crafting your own mold, just remember to seal it fully so wet concrete won‘t leak out. Get as creative as you want!
Mixing and Pouring Concrete – Step-By-Step
Once you‘ve selected the perfect mold, it‘s time to mix and pour the concrete. Follow my proven step-by-step instructions for smooth, spill-free pouring:
Gather Supplies
- 2-3 bags concrete mix (80 lb. bags)
- Mold (prepared and oiled)
- Wheelbarrow or large bucket
- Concrete mixing hoe or shovel
- Measuring bucket
- Trowel
- Decorative aggregates (optional)
Mix Concrete
- Pour 80 lbs concrete mix into wheelbarrow or bucket.
- Add 5-6 quarts of water. Mix thoroughly until blended to a pourable consistency.
Pour Concrete Into Mold
- Slowly pour concrete into mold, tilting to evenly distribute.
- Tap sides with trowel to release air pockets.
- Optional – Press decorations like pebbles into surface.
- Smooth top with trowel for finished look.
Allow Concrete to Cure
- Cover mold with plastic sheeting.
- Allow concrete to cure for 2-4 days.
- Once fully hardened, carefully unmold birdbath.
And just like that, your concrete birdbath bowl is ready! Let the concrete cure fully before gently removing your mold.
Installing and Placing Your Bird Bath
Once your concrete birdbath is fully cured and unmolded, it‘s time to install it in your landscape. Here are my best tips for optimal placement:
Ground Mounted
Simply place your finished concrete bowl directly on the ground where desired. I recommend:
- Setting in a partially shaded spot so water doesn‘t get too hot.
- Facing it near trees or shrubs to give birds shelter.
- Burying the base 1-2 inches underground for added stability.
This creates an organically integrated, earthy look.
Elevated on Pedestal
For more visibility, elevate your birdbath bowl on a pedestal, column, or stack of fieldstones. Try:
- Placing on a concrete paver column for modern style.
- Using a natural stone pillar for rustic elegance.
- Elevating 3-4 feet high for optimal bird access.
The raised profile highlights your handcrafted bowl.
Location Considerations
Wherever you install your birdbath, consider:
- Situating within view of shrubs or trees to make birds feel safe.
- Avoiding deep shade, which can foster algae growth in water.
- Letting birds hear the sound of wind chimes or running water to attract them.
Carefully selecting the location with birds in mind will ensure your new concrete basin gets lots of visitors!
Decorating Your Concrete Birdbath Bowl
One of the joys of concrete is that it can be embellished, painted, stained and customized in all sorts of ways. Here are some fun and easy decoration ideas to make your birdbath uniquely yours:
Mixed Media Mosaic
Embed tiles, marbles, gems, mirrors or beads while the concrete is still wet for a shimmering mosaic motif.
Seashell Surprise
Press shells collected from the beach into the concrete to create a coastal vibe.
Pebbled Path
Outline the bowl‘s edge with smooth stones for an organic look.
Glass Jewels
Crushed glass or marbles add a surprising pop of color.
Handprints
Memorialize your little one‘s hands in concrete with their palm print.
Faux Rock
Sculpt the uncured concrete with tools to mimic natural rock.
Stained Concrete
Apply colored concrete stain in your favorite hue for affordable artistry.
Let your creativity run wild! The options for decorating and personalizing your concrete bird bath bowl are endless.
Caring for Your Concrete Bird Bath
To keep your birdbath looking pristine for years and provide birds with fresh water, be sure to:
- Change water every 2-4 days, or daily in hot weather when water gets dirty or evaporates.
- Clean bowl thoroughly each time with mild, bird-safe cleaner to prevent algae.
- Reseal annually with concrete sealer to protect from weathering.
- In winter, drain bowl and bring indoors if temperatures fall below freezing.
With proper care and maintenance, your handcrafted concrete birdbath will stay beautiful while providing birds with high quality habitat.
