Grill Box Konro Grill
A British made charcoal grill designed for konro precision, robata grilling, and open fire cooking over glowing embers.
Product Description
The Grill Box Konro Grill is a versatile charcoal grill designed for cooks who appreciate the craft and flavour of cooking over live fire. Built entirely from stainless steel and manufactured in Great Britain to a high engineering standard, it combines the precision of Japanese konro grilling with the relaxed theatre of open fire cooking.
At the heart of the range, the Grill Box Konro Grill forms the central firebox and foundation of the Grill Box Fire Cooking System. A range of interchangeable Grill Box cooking frames and accessories can be added to adapt the grill for different styles of live fire cooking, from robata skewers to asado style grilling.
With a generous 750 mm cooking area, the Grill Box provides ample space for grilling steaks, seafood, vegetables, or robata style skewers over glowing charcoal. The design concentrates heat beneath the cooking surface, producing the intense radiant heat that makes charcoal grilling so distinctive.
Inside the grill, replaceable vermiculite fire bricks help retain and stabilise heat while protecting the stainless steel body from sustained high temperatures. An internal stainless steel grate supports the charcoal bed, allowing air to circulate through the fire for efficient combustion and consistent heat.
A practical ash tray drawer makes cleaning simple, allowing spent charcoal and ash to be removed easily after cooking.
Operating at temperatures of up to 400°C, the Grill Box is suited to both fast grilling and more controlled cooking over embers. Its compact footprint makes it ideal for patios, terraces, and outdoor kitchens, while the Grill Box Fire Cooking System allows cooks to expand the grill with specialised cooking frames designed for different techniques and ingredients.
Whether preparing yakitori skewers, grilling vegetables over glowing coals, or searing steaks over hardwood embers, the Grill Box Konro Grill delivers precision charcoal heat and exceptional versatility.

What is a Konro Grill?
A konro grill is a traditional Japanese charcoal grill designed to produce intense, controlled heat within a narrow cooking chamber. This concentrated heat allows food to cook quickly while retaining moisture and flavour.
Konro grills are commonly used for dishes such as yakitori, seafood, and small cuts of meat cooked over high quality charcoal such as binchotan. The design encourages precise cooking and makes it easy to manage heat across the grill.
The Grill Box takes inspiration from this style of cooking, offering the same focused charcoal heat in a robust stainless steel format suitable for outdoor kitchens and patios.
Why Vermiculite Fire Bricks Matter
The interior of the Grill Box is lined with replaceable vermiculite fire bricks, an important feature in high temperature charcoal grills.
Vermiculite bricks help to
• retain heat within the cooking chamber
• stabilise cooking temperatures
• protect the outer steel structure from extreme heat
• improve fuel efficiency during longer cooks
Because the bricks are replaceable, the grill can continue performing reliably even after years of regular use.
Choosing the Right Charcoal
The Grill Box performs best with high quality charcoal or hardwood embers.
For precise grilling, many cooks choose binchotan charcoal, a traditional Japanese charcoal known for its clean burn and steady heat. Binchotan produces very little smoke and allows the natural flavour of food to shine through.
High quality lump charcoal also works well, particularly when grilling steaks, vegetables, and larger cuts of meat.
By managing the charcoal bed and adjusting the cooking height, the Grill Box allows you to move between intense heat for searing and gentler heat for slower grilling.
