Transform your porch with these stunning organic faux-stone planters made from an unlikely material: cheap plastic shower caps. By crusting these caps in heavy gray cement, you can create unique, artisan-style planters that mimic the look of stone without the hefty price tag. This DIY project provides an economical way to add a touch of sophistication and creativity to your outdoor space, impressing your neighbors and enhancing your home's curb appeal.
Place these faux-stone planters symmetrically on either side of your porch steps to create a balanced and inviting entrance. Pair them with vibrant, contrasting flora such as bright green ferns or colorful petunias to make the planters' gray tones pop. Coordinate with other neutral-toned outdoor decor, like a gray welcome mat or stone garden statues, to maintain a cohesive aesthetic.
Cement-Crusted Shower Cap Planters

Materials
60 cheap plastic shower caps
Heavy gray cement mix (approximately 20 kg)
Large mixing bucket
Trowel or spatula
Plastic drop cloth
Rubber gloves
Protective mask
Water (as needed for cement mix)
Sandpaper (medium grit)
Directions
Lay out a plastic drop cloth in your working area to protect surfaces.
Put on rubber gloves and a protective mask to ensure safety while handling cement.
Mix the heavy gray cement in a large mixing bucket according to the manufacturer's instructions until it reaches a thick, workable consistency.
Take a plastic shower cap and fill it with a small amount of the cement mixture, ensuring it is evenly distributed inside the cap to form a smooth, rounded shape.
Place the cement-filled cap on the drop cloth, ensuring it sits securely without tipping over. Repeat the process with the remaining shower caps.
Allow the cement to set partially (about 30 minutes) until it is firm but not fully hardened.
Once the cement has partially set, gently remove the plastic caps from the cement shells, leaving a rough, textured surface.
After removing all caps, let the cement planters cure completely for 24 to 48 hours.
Once fully cured, use medium-grit sandpaper to smooth out any sharp edges or uneven surfaces on the planters.
Position the finished planters on your porch and fill them with soil and your choice of plants.

Variations & Tips
For a more colorful twist, consider adding powdered pigments to the cement mix to create planters in a range of earth tones. Alternatively, try using different shaped molds, like balloons or fabric sacks, to vary the size and form of the planters. To enhance durability, you could also seal the planters with a clear water-resistant sealant, which will help them withstand outdoor elements longer while maintaining their aesthetic.
