Step2 Atherton Square Planter — 24" Onyx Black Tall Outdoor/Indoor Planter with Water Reservoir and Drainage Control

The Step2 Atherton Square Planter is a 24-inch tall, durable onyx-black planter with an integrated water reservoir and customizable drainage for easier plant care.

Designed for patios, porches, balconies, and entryways, the Atherton planter combines a modern square silhouette with practical performance. Its 24" height and 15.5" width/depth give ample soil volume for shrubs, ornamental grasses, and mixed floral displays while keeping plants elevated and visible. Built from double-walled, molded resin in a fade-resistant onyx black, the planter resists chipping, cracking, and corrosion so it stays attractive season after season.

How does the built-in water reservoir simplify watering?

The internal water reservoir stores extra moisture so you can water less frequently while still supporting steady root moisture. A removable plug lets you control whether the reservoir is active, and the reservoir design also helps stabilize the tall planter against light wind and accidental nudges.

• Holds a reserve of moisture to reduce watering frequency.
• Removable plug for choosing reservoir or full drainage.
• Even moisture distribution supports healthy root development.
• Adds weight low in the base to improve planter stability.

Can I use it for both indoor and outdoor plants?

Yes—the Atherton performs well indoors and outdoors. Its weatherproof resin resists UV fading and moisture damage outdoors, while the clean square profile and onyx finish make it suitable for entryways, sunrooms, or interior gardens.

• Double-walled resin tolerates sun, rain, and temperature changes.
• Pre-assembled and ready to use right away.
• Neutral onyx color complements most décor styles.
• Optional drainage points allow customization for indoor setups.

What about drainage and preventing overwatering?

The Step2 Atherton offers versatile drainage options so you can match the planter to your plants' needs. Molded drill points let you add permanent drainage if you grow water-sensitive species, while the reservoir plug allows you to retain moisture when appropriate.

• Factory-drilled points are available for user-installed drainage holes.
• Removable plug enables reservoir use or full bottom drainage.
• Designed to support both moisture-loving and drought-tolerant plants.
• Internal layout promotes air circulation to roots when drained.

How durable is the construction for long-term use?

Constructed from molded-in-color, double-walled plastic, the Atherton is built to withstand everyday use and outdoor elements. The finish won’t flake or rust, and the structure resists cracking so the planter keeps its shape and appearance across seasons.

• Molded-in pigment prevents peeling or fading of the finish.
• Double-walled resin improves impact resistance and insulation.
• Weatherproof materials are suited for year-round outdoor display.
• Easy-to-clean surface for low-maintenance upkeep.

Who is this for? The Step2 Atherton Square Planter fits gardeners and decorators who want a tall, stylish container that reduces watering chores and lasts outdoors. It’s ideal for homeowners adding height to patios, renters wanting a polished porch focal point, and anyone who prefers low-maintenance planters that still give plants plenty of soil volume.
