20 Inch Extra Large Plant Saucers - Extra Deep 3.7 in Drainage Trays

Our review finds these 20 in extra large plant saucers are best for gardeners who need serious water containment under large pots. The single biggest reason to buy is the exceptional 3.7 in depth, which gives more capacity than typical saucers and prevents frequent overflow when watering or during heavy rains if used outdoors. This review focuses on practical use: sturdy heavy-duty plastic construction, good footprint for 16-18 in bases, and simple maintenance, making them a straightforward solution for protecting floors and patios.

Key Features

• Extra depth: The 3.7 in deep well captures excess water and soil, reducing spills and keeping indoor surfaces dry.
• Large diameter: A 20.5 in top diameter with an 18.5 in bottom footprint fits wide base planters and offers stable coverage for big pots.
• Thickened construction: Heavy-duty PP plastic gives rigidity and can support heavy planters without flexing under load.
• Waterproof protection: Fully sealed design prevents leaks, protecting furniture, deck boards, and patios from water damage.
• Indoor and outdoor use: UV- and weather-tolerant plastic means these trays can be deployed on porches or in living rooms without worry.
• Neutral design: The round black tray pairs with ceramic, clay, and plastic pots without clashing with common planter styles.

Who It's For

These saucers are ideal for plant owners with large containers, such as 16 to 18 in base pots, who need substantial water retention between watering cycles or when growing moisture-loving plants. Apartment gardeners, greenhouse users, and patio planters will appreciate the depth and robust material for protecting varnished floors, furniture, and decking.

They are less suitable for very small nursery pots or decorative situations where a visible tray may clash with the aesthetic; users seeking drainage-only trays with holes for self-watering systems should look elsewhere.

Pros & Cons

Pros

• Deep 3.7 in capacity holds runoff for longer periods, reducing frequent emptying.
• Sturdy, thick PP plastic construction supports heavy planters without cracking.
• Large 20.5 in top diameter covers bases up to around 18 in, accommodating oversized pots.

Cons

• The saucer has no drainage holes, so standing water must be emptied manually to avoid overwatering if that is a concern.
• Its large size can be bulky to store when not in use.
