Tall Planters: Choosing Height, Shape and Stability for Lobbies and Entrances

A tall planter for a lobby or entrance should be chosen by height first, then by top diameter, then by whether it stands indoors or outdoors. As a simple guide, pick a height that suits the door or wall behind it, and a wider top wherever people will pass close by or wind can reach it.

Which tall planter sizes are available?

LineSizes (diameter x height)Drainage plate
Calista18" x 30", 21" x 35"Without plate
Prisma12" x 18", 16" x 24", 20" x 30"With plate
Kosmos12" x 18", 14" x 24"Without plate
Stylos12" x 18", 12" x 24"Without plate
Atlantis12" x 12", 12" x 18", 15" x 15", 15" x 24"With plate
Hycross12" x 25"Without plate

All six lines are in the Roto Premium Series, UV protected, in Beige Stone, White Stone and Gray Stone.

How tall should a planter be?

  • Lobby or reception: tall lines such as Calista at 30" or 35" hold their own in a large room.
  • Beside a door: a pair at 24" to 30" frames the entrance without blocking the way.
  • Corridor or narrow wall: a slim line, such as Stylos at 12" x 24", leaves walking room.

How do you keep a tall planter stable?

A tall, narrow pot tips more easily than a wide one, especially outdoors. Choose a wider top where wind or foot traffic is a concern, set the pot on a level floor, and keep its weight low by filling the bottom with soil rather than leaving it hollow. Compare the top diameter with the height before you order: a 20" x 30" Prisma is a far more settled shape than a 12" x 25" Hycross.

Do you need a drainage plate?

Indoors, on stone or wood floors, water must not reach the floor. Prisma and Atlantis come with a plate. For Calista, Kosmos, Stylos and Hycross, plan for how the water will be caught, or use a closed liner pot inside.
