The Austin Saucer collects excess water drainage and soil spillage from your flower pots. Protect your hardwood floors, carpets, decks, and furniture from those harmful water stains and rings plants often leave with our sturdy, re-usable plant saucers. Best way to find the correct saucer is to turn the flowerpot over and measure the bottom diameter. Select a saucer with base diameter about 2 inches larger. Austin Planter saucers are flat on the inside so you can use any size pot that fits the saucer and even several small pots in one saucer.
