The by CALLAHEAD™ is not just a portable restroom — it is a one-of-a-kind work of art unlike anything anywhere in the world. Designed by Charles W. Howard, President and CEO of CALLAHEAD™ — an award-winning builder, designer, and prolific inventor — the brings the atmosphere of an old-world New York steakhouse to any outdoor location. The instant the door opens the striking design leaves a lasting impression.
Once you step inside the , the interior feels more like a custom-built room than a portable unit, with rich black walls framed in warm wood trim and highlighted by elegant gold accents throughout. A gorgeous wood vanity with gold trim provides storage and supports a porcelain sink with hot and cold running water, set beneath a striking gold leaf mirror that immediately recalls an old-world New York steakhouse. A gold soap dispenser and hand dryer are wall mounted above the sink for convenience. A porcelain pedal low flush toilet bowl sits beside a beautifully detailed gold toilet paper holder. Overhead, thermostat-controlled air conditioning and a wall mounted fan forced heater ensure year-round comfort. The gold trimmed decorative ceiling lighting washes the roomy interior in a warm, flattering glow, completing a look that feels permanent, luxurious, and unlike any portable restroom ever seen.
Charles W. Howard has been building, designing, and inventing for CALLAHEAD™ since the age of 12, dedicating his life to transforming portable sanitation from a basic necessity into an elevated experience. Since 1976, CALLAHEAD™ has been recognized as the world’s greatest portable sanitation company, continually introducing industry “firsts” that others try to imitate but can never equal. Guided by the CALLAHEAD™ mission statement, “To Develop and Evolve a Human Necessity”™, CALLAHEAD™ creates exclusive equipment that looks, feels, and performs far beyond the expectations of a typical portable restroom. The is one of his most striking expressions of that vision — designed by Charles W. Howard and manufactured exclusively and available only by CALLAHEAD™.

Since 1976, CALLAHEAD™ has operated exclusively in New York, allowing the company to focus 100% of its effort on serving New York’s construction, commercial, and special event markets with unmatched attention to detail and customer service.
Today, CALLAHEAD™ is New York’s oldest portable restroom company, and its long history of original inventions, patented systems, and designer restrooms has made CALLAHEAD™ the definitive expert in the portable sanitation industry. By designing and manufacturing its own equipment and serving only New York, CALLAHEAD™ maintains total control over quality, innovation, and responsiveness, delivering a level of consistency and excellence that no other company can match.
The name PORTERHOUSE was chosen because every aspect of this restroom is inspired by the warmth and sophistication of an old-world New York steakhouse like Peter Lugars.
From the outside, the stands out instantly:
Center stage on the exterior is the CALLAHEAD™ gold signage: a heavy, engraved plaque reading “CALLAHEAD™ NEW YORK”. Set against the textured black wall and framed in brushed gold, this plaque looks like the nameplate on an exclusive private club. It signals immediately that this is a CALLAHEAD™ original and that nothing about this restroom is ordinary.
Step inside and the steakhouse concept is fully realized:
The experience leaves a powerful, positive impact that feels truly exhilarating. Guests enter expecting a portable unit and instead find themselves in what feels like a permanent, high-end restaurant restroom. There is simply nothing else like it anywhere in the world.
Charles W. Howard’s quote, “Perfection is a Matter of Opinion Therefore it Exists”™, is fully visible in the . Every material, proportion, and detail has been chosen to achieve his personal vision of a perfect single user luxury portable restroom.
The uses gold accents not as decoration alone, but as part of a carefully orchestrated design language:
Even the overhead lighting has been elevated. Each recessed light is surrounded by an intricately patterned gold trim ring, turning a simple ceiling light into a piece of jewelry set into the dark ceiling. This warm, focused light highlights the wood, gold, and porcelain, adding drama and depth to the space.
The CALLAHEAD™ AIRWAVE™, a wall-mounted black hand dryer, complements the gold and wood accents by blending seamlessly into the black wall panel. This design helps keep the interior clean and efficient without disrupting the overall aesthetic.
The reinforces its true indoor bathroom feel with a beautifully detailed porcelain vanity and fully functional wash area. A white porcelain sink is set into a rich wood vanity with elegant gold accents, providing both visual warmth and practical counter space. Above the sink, a 20” x 16” antique brass vanity mirror creates a classic steakhouse look, while a stainless brass wall-mounted soap dispenser and brass designer towel ring holder keep everything within easy reach. For touch-free drying, a wall-mounted CALLAHEAD™ AIRWAVE™ hand dryer is installed, maintaining cleanliness and reducing paper waste. The sink is supplied with hot and cold running water heated by a Braun hot water heater and delivered through a chrome-plated brass automatic shut-off faucet, ensuring proper handwashing while conserving water. Together, these elements make the wash area feel indistinguishable from a high-end indoor restroom.
The is equipped with a premium Sealand by Dometic® porcelain flush toilet bowl, the same low-flush toilet trusted throughout the marine industry on luxury yachts. This is not a plastic porta potty seat, but a true, full-weight porcelain bowl that gives users the solid, secure feel of a permanent indoor restroom. The toilet operates with hands-free, foot-pedal flushing, allowing the user to flush without touching any levers or handles, which greatly enhances hygiene. Its low-flush design is engineered to conserve water while still delivering a powerful, clean rinse every time. By specifying a Sealand by Dometic® marine-grade porcelain toilet, CALLAHEAD™ ensures the offers the same level of quality and performance found on high-end yachts and luxury vessels for the best possible restroom experience.

Wherever the is placed, it sends a clear message: you care about quality and image to the highest degree.
The is engineered with a sophisticated, completely self-contained plumbing system that delivers true indoor bathroom performance while maintaining the highest sanitary standards. The porcelain sink with hot and cold running water operates on its own dedicated fresh water tank and on-demand pump, while the low-flush porcelain toilet bowl is supplied by a separate fresh water tank and its own independent pump. By keeping the sink and toilet water systems completely separate, the design eliminates any risk of cross-contamination and ensures maximum hygiene. The low-flush toilet functions just like a home toilet, giving users a familiar, comfortable experience while conserving water with every flush. All fresh water and grey/waste water tanks are equipped with exterior marine-grade inspection hatches, making refilling and servicing both clean and efficient. Because everything is fully integrated inside the unit, the arrives at your site as a completely self-contained restroom, ready to operate without any on-site plumbing connections.
