Custom container fabrication

Containers, built
to your spec.

Storage, offices, pools, saunas, ADUs, short-term rentals — and just about anything in between. Built in-house at our Toledo yard. Permitting available.

What we build

If you can describe it, we can probably build it.

From simple door-and-vent modifications to fully insulated, HVAC- and plumbing-equipped lifestyle builds — pools, saunas, ADUs, pool houses, yoga studios, you name it — our in-house crew handles the full fabrication pipeline at our North Toledo yard. Design, cutting, welding, electrical, plumbing, finish work, optional permitting. No subcontractors. No middlemen. One crew, one shop, accountable for every weld. The list below is a starting point — not a limit.

  • Doors & access

    Rollup, double, man-doors, dutch doors, and custom security doors — cut, framed, and finished in-house.

  • Windows & vents

    Glass windows with security bars, passive vents, and powered ventilation systems for HVAC-equipped builds.

  • Electrical & HVAC

    Full electrical panels, lighting, outlets, climate control. Engineered for permanent installation or portable use.

  • Insulation & interiors

    Spray foam, batt insulation, finished walls, flooring, partitions — office, shop, restroom, lifestyle, or living configurations.

  • Plumbing & wet builds

    Pools, saunas, cold plunges, pool houses, and bathrooms — water-tight, code-aware, professionally built.

  • Custom paint & wraps

    Any color, corporate branding, blackout, hi-vis safety. Vinyl wraps available for event and mobile-shop applications.

  • Decks & rooftops

    Rooftop decks, exterior decks, stairs, railings, lighting — engineered for the climate and the use case.

  • Built in-house

    No subcontracted middlemen. Our crew designs, cuts, welds, wires, plumbs, and finishes everything on our Toledo yard.

Container fabrication questions

The questions every buyer asks.

Timelines, costs, custom finishes, lifestyle builds, permitting — straight answers.

  • What kinds of container modifications do you offer?

    We modify shipping containers for an enormous range of uses — anything from job-site storage and security shacks to backyard pools, saunas, cold plunges, yoga studios, in-law suites, short-term rentals, pool houses, man-caves, she-sheds, containers with rooftop decks, and just about anything in between. Capabilities include custom doors (rollup, double, man-doors, dutch doors), windows, vents, electrical wiring and panels, HVAC, insulation, plumbing, partitions, custom paint, vinyl wraps, decks, and bespoke layouts. If you can describe it, we can usually build it — bring us your idea.
  • Do you build residential container conversions like pools, saunas, and ADUs?

    Yes — we build shipping container pools, pool houses, pool-bar combos, saunas, cold plunges, yoga studios, in-law suites, backyard ADUs, short-term rental modular units, man-caves, she-sheds, guest cabins, and containers with rooftop decks. Every lifestyle build is custom. Call us with your vision and we will scope it out.
  • Do you handle permitting for custom container builds?

    For custom builds that require permits, we offer full white-glove permitting and project management with your local township and building department. Each project is too specific for us to publish a rate sheet, but we are happy to build you a tailored proposal — please inquire. Otherwise, check with your local township and building department for permitting requirements.
  • How long does custom container fabrication take?

    Standard modifications (cutting doors, adding vents, basic electrical) typically take 2 to 3 weeks. Full custom builds with insulation, HVAC, plumbing, finished interiors, and custom paint can take 6 to 12 weeks depending on the spec. Lifestyle builds like pools or ADUs with permitting can take longer — we will be straight about timing on the first call.
  • Can you build containers with custom paint colors or vinyl wraps?

    Yes. We finish in any color — corporate branding, blackout, hi-vis safety, you name it. Vinyl wraps are also available for branded containers used at events or as mobile shops.
  • Do you fabricate containers for permanent installation?

    Yes. We modify containers for permanent on-site use (security shacks, equipment housings, restroom modules, ADUs, in-law suites, pool houses, mobile offices that will not be relocated). For permitted permanent installations we can coordinate the full project — see our permitting service.
  • What's a typical cost range for a custom container build?

    Basic modifications start at a few thousand dollars. Fully built-out, insulated, HVAC-equipped office or shop conversions can run $25,000 to $60,000+. Lifestyle builds (pools, saunas, ADUs, pool houses) vary widely based on size, finishes, and whether permitting is included. Call 419-745-9492 for a tailored quote.
