20ft High Cube Pre-Owned Steel Container
From $1,450 / unit
Tall sealed unit at a working-class price —
The 20ft High Cube WWT container pairs the extra foot of ceiling height with a price tag that respects your renovation budget. Fully sealed against Florida’s rain and humidity, this unit protects your contents and your build-in-progress while you work through the conversion at whatever pace suits you.
A sensible choice for surfboard and kayak storage, tall equipment shelters, vertical gardening setups, and standing-height workshops throughout St. Petersburg. The 9'6" exterior height means you can store items vertically or build in a mezzanine shelf system that would be impractical in a standard-height container. The sealed envelope keeps moisture out while you plan your next move.
Cosmetic condition reflects honest use — surface oxidation, dings, and wear marks are part of the package at this price tier. For builders who value function and headroom over appearance, the 20ft HC WWT delivers the tall-ceiling advantage of a High Cube without the cost premium of certified or One-Trip grades.

Modification Advantages for Building Projects
The 20ft High Cube ranks among the most versatile containers for conversion work. Here is what makes it a preferred starting point for builders and property owners:
- Roughly 150 sq ft of habitable floor area — room for a complete one-bedroom layout including kitchen, bathroom, and lounge
- 8'10" raw interior ceiling — once insulated and framed, you retain about 8' of finished headroom, satisfying typical residential code requirements
- Weathering steel (Corten) shell — self-protecting steel that forms a rust-resistant patina, engineered to endure 25-50+ years along Florida's Gulf Coast
- Works with conventional framing — inner measurements support standard 2x4 stud walls paired with closed-cell foam, so any licensed contractor can handle the job
- Full-width rear doors — keep them for a statement entrance, swap them for floor-to-ceiling glazing, or seal and reframe for additional wall area
- 28mm marine plywood subfloor — delivers a flat, sturdy base ready to accept any final flooring finish
- Modular and stackable — arrange units side-by-side or on two levels to form multi-room or two-story configurations
Did You Know?
Converting a 20ft High Cube typically runs 40-60% below the cost of conventional stick-frame construction for equivalent square footage. Across St. Petersburg, property owners are turning to container-based ADUs (Accessory Dwelling Units) to earn rental income or provide housing for family.
Florida has become increasingly ADU-friendly, with new legislation making it easier to add a container-based dwelling to your property.
Understanding the Wind & Water Tight Classification
Wind & Water Tight (WWT) containers are retired ocean freight units that remain fully sealed against the elements. They no longer carry CSC certification for international shipping, but they keep rain, wind, and pests out reliably — exactly what most building and storage projects require.
Expect visible signs of service life: surface rust, dents, scratches, and general patina. The structural bones — corner posts, floor crossmembers, and roof bows — are intact and solid. Doors open and close properly and seals are functional.
WWT is the sweet spot for budget-conscious builders who plan to insulate, frame, and clad the interior anyway. Cosmetic imperfections disappear behind finished walls, making the lower price point a smart investment for workshops, storage buildings, and value-oriented living spaces.
Wind & Water Tight Grade Includes:
- Sealed against wind & rain
- Structural frame intact
- Functional door seals
- Solid floor condition
- Corner castings intact
- Secure locking hardware
Sealed against wind and rain but no longer certified for ocean freight. Visible signs of service life — surface rust, dents, patina. Solid choice for storage, workshops, and budget-conscious builds.
