Converting an Antique Clawfoot Bathtub into a Pond: Plants, Equipment, and Fish

Bathtub Pond: A Charming Mini Water Garden

An antique clawfoot tub makes a beautiful, portable pond. Here's how to set it up for success.

Plants for Water Clarity

• Water lilies – one dwarf variety shades the surface.
• Floaters – water hyacinth and/or water lettuce (excellent nutrient sponges).
• Submerged oxygenators – anacharis or hornwort.

Order from a reputable aquatic nursery (e.g., Pond Market).

Equipment

• Small submersible pump + filter – Pondmaster systems are reliable.
• pH test kit.
• Dechlorinator (if using tap water).
• Beneficial bacteria starter.

Fish Choice: Shubunkins Over Koi

Most tubs hold <100 gallons. Koi grow >3 feet and jump. Shubunkins stay smaller, tolerate tub conditions, and offer gorgeous calico patterns.

Winter Care (Zone 5–6)

Move tub to a garage/basement, keep aerated, or bring fish indoors. Floaters rarely survive indoors without strong grow lights.

Enjoy your elegant, movable water feature!
