Restaurant and Bar Millwork Shop Drawings: What Every Set Must Cover

A restaurant bar is one of the most technically complex single millwork elements in commercial construction. It involves custom wood fabrication, equipment integration, plumbing, electrical, lighting, refrigeration, and draft beer systems — all of which have to be resolved on paper before the first board is cut. A shop drawing that treats a bar like a cabinet run will produce a bar that fails on installation day: equipment doesn't fit, drains conflict with structure, and the brand's finish spec isn't met.

This guide covers what every restaurant and bar millwork shop drawing must document — from bar top heights and back bar configurations to equipment coordination, health department surface requirements, and the multi-party review process that governs hospitality projects. For projects that need professional millwork shop drawing services for hospitality environments, this is the standard we work to.

Bar Top Heights and Key Dimensions

Restaurant bar millwork involves at least three distinct work surface heights in a single unit, and all three must be explicitly dimensioned in the drawing:

The cross-section drawing through the bar is the most important single view in the package. It must show all of these heights simultaneously — relative to each other and to the finished floor — along with the underbar equipment zone and the structural elements (bar rail support, footrail bracket location, toe board construction).

Front Bar: Underbar Equipment Coordination

The space below the bar top on the bartender's side — the "underbar" — is occupied almost entirely by equipment. The millwork drawing has to accommodate this equipment precisely or the bar doesn't function.

Ice storage bin. The ice bin is typically the largest single underbar item and should be located closest to the draft beer tower for fill efficiency. Standard underbar ice bins are 24″ or 30″ wide × 24″ deep × 34″ tall. The drawing must show the bin cut-in opening in the underbar structure, drain connection, and access clearance for the ice delivery opening (which is at the top, above the bar top surface).

Bottle cooler / back bar refrigerator. Underbar coolers are typically 24″ or 36″ wide with a standard 34″ height. The drawing must show the cooler opening dimensions and the refrigerant compressor clearance at the rear. Many underbar coolers exhaust from the front — the drawing must confirm the front clearance is not obstructed by a toe kick.

Glass washer. The three-compartment bar sink and glass washer are code requirements in most jurisdictions for any bar serving alcohol. The sink requires a cold water supply, hot water supply, and a drain — all of which must be shown in the shop drawing with rough-in locations. The glass washer requires an electrical connection (typically 120V or 208V depending on model) at a specific location within the underbar structure.

POS terminals and data conduit. POS terminal locations must be coordinated with the bar millwork drawing — typically one terminal per bartender station, located on a shelf at approximately 40″–42″ height, with data conduit routed through the bar structure from below. The drawing must show conduit stub-up locations relative to the millwork structure.

Draft beer tower. The draft beer tower mounts through the bar top. The shop drawing must show the mounting hole diameter, the tap tower footprint clearance on the bar top surface, and the routing of beer lines from the keg cooler (which may be in a remote cooler room) through the bar structure. Beer line insulation sleeve routing must be shown in the section view.

Back Bar: Display, Storage, and Lighting

The back bar is the millwork unit against the wall behind the bartender and is typically the most visually prominent millwork element in the space. It serves multiple functions — liquor display, glassware storage, refrigeration, and POS display — and the shop drawing must address each one.

Upper display shelving. Open glass shelving for liquor display is standard. The drawing must show the shelf standard type (aluminum recessed standards are most common), shelf material (typically 3/8″ or 1/2″ tempered glass with polished edges), shelf spacing (typically 12″–14″ between shelves for liquor bottle height), and the back panel — mirror, backlit panel, or decorative material — behind the shelving. Glass shelf weight limits must be noted.

LED lighting integration. Shelf lighting (in-shelf LED strip or individual puck lights) and the back panel illumination detail must appear in the drawing. This means showing the LED driver location (typically inside a closed cabinet compartment), wiring routing through the millwork structure, and the locations of all light fixtures relative to the shelf positions. Electrical coordination for the lighting feed must be addressed.

Lower cabinet storage. The lower back bar section typically houses glassware, bar tools, and backup stock. Show drawer and door configurations, interior fitting layouts (pull-out tray details, glass rack dimensions if specified), and access panel locations for any utility connections routed through this zone.

Health Department and NSF Surface Requirements

Restaurant and bar millwork in food and beverage contact areas is subject to health department review, and the surface specifications must appear in the drawing to pass that review. The key requirement: all surfaces in food or beverage contact areas must be smooth, non-porous, and easily cleanable.

In practice, this means:

• Exposed wood in food prep zones is not compliant. Bar tops in food service areas must be finished with a sealed, non-porous material — solid surface, quartz, stainless steel, or phenolic-core laminate (NSF-certified grades). The drawing must specify the countertop material and NSF certification where applicable.
• Interior cabinet surfaces in food storage zones must be smooth and sealed. A painted interior or plastic laminate liner is standard. Show the interior finish in the drawing notes.
• Coved base. At floor-to-wall junctions in food service areas, a coved base (typically 4″ radius cove) is required to prevent accumulation of debris. This must be shown in the base detail.
• Grease-resistant surfaces near cooking equipment. Any millwork within the specified clearance of cooking equipment must be non-combustible or protected. Coordinate with the mechanical drawings for hood and exhaust clearances.

Brand Standards and Multi-Unit Restaurant Projects

For chain restaurant or franchise projects, the millwork drawing must demonstrate compliance with the brand standard. This is a formally documented requirement — the brand's design development package specifies exact materials, finishes, dimensions, and sometimes hardware model numbers. The fabricator's shop drawing is reviewed against the brand standard, not just the local architect's CDs.

What this means for the drawing:

• Material specifications must reference brand standard codes (e.g., "Wilsonart D354-60 High Gloss per Brand Standard v4.2")
• Color and finish notes must include brand color codes, not just generic descriptions
• Dimensional compliance notes must reference the applicable brand standard section
• Any design deviation from the brand standard — even a minor substitution due to material availability — must be flagged and approved through the brand's design review process before the drawing is submitted

Multi-unit rollout projects (where the same design is being built simultaneously in multiple locations) add a layer of complexity: the drawing set must be adaptable to different field conditions across locations while maintaining brand compliance. See our retail millwork shop drawings guide for how multi-location rollout coordination works in practice — the same principles apply to restaurant chains.

The Review and Approval Process

Hospitality millwork submittals typically involve more reviewers than a standard commercial project. Depending on the project delivery method, the drawing may need to be approved by the general contractor, the architect, the interior designer, the owner's representative, and the brand's design review team — sometimes sequentially, sometimes in parallel.

The millwork drafter should expect at least two revision rounds on a complex bar package. The first round typically addresses equipment coordination conflicts and dimension discrepancies. The second round addresses finish and specification details. Building in this expectation when scheduling the drawing phase prevents schedule compression at fabrication. See our detailed guide on how the millwork submittal process works for the full review chain structure. For restaurant millwork drawing rates, bar packages are priced as complex scope due to the coordination requirements — typically 4–6 hours per station for full cross-section and equipment coordination documentation.
