Building an Indoor or Patio Pond on a Cement Porch

Stephanie wants a pond but only has a cement porch and a tiled house. Robyn suggests above-ground options: cement, fiberglass, preformed plastic, or a liner over a wooden frame. She also recommends considering a larger aquarium (e.g., 120 gallons) as a simpler alternative.

Key Questions

• How much space on the porch and indoors?
• What species and size are the 7 fish in the 20-gallon tank?

See indoor pond guide for design ideas. An open indoor pond costs less than a large aquarium but has different challenges.
