How to Spec Marble for Hotel and Commercial Lobbies

For hotel and commercial lobbies, a stone name alone is not a specification. Finish, thickness, slip performance, lot control, and attic stock must appear in the documents—or installation and maintenance will drift. Drawings often say only “white marble,” samples are hand-sized, and the floor may cover hundreds of square meters: tone breaks appear, or slip issues surface at the entrance.

Design teams protect first impression and brand; procurement and PMs watch schedule and claims; installers worry about lots, joints, and floor levels. This guide focuses on what to write into the specification for hotel, office, and retail lobbies—by zone, finish, thickness, inventory, and approval. Browse Products for variety tone, and Projects for similar spaces, so technical discussions move faster.

Why a Spec Cannot End With “One Sample”

Lobbies often run one material across floor, walls, reception, and elevator halls. Natural stone varies by block and lot in ground and vein; without a documented approved range, later deliveries become “same name, different stone.” For white-variety comparison, see the Carrara, Calacatta, and Statuario guide; for roles of marble versus granite, see the marble and granite guide.

Lobbies also combine luggage carts, umbrellas, entrance moisture, and daily cleaning. Polish reads strongly in dry interiors, but entrances and outdoor-air intake zones with frequent moisture need separate review for slip and gloss wear. ANSI A326.3–family guidance, widely cited for hard-floor slip discussion, separates use classifications such as Interior Dry and Interior Wet, and often references wet DCOF around 0.42 as a minimum for level-surface foot traffic. Always follow local codes and owner standards—yet pairing finish type + application zone in the specification still reduces disputes.

1. Split the Zones Before You Write the Spec

A zone map comes before a one-line material note.

• Zone — Primary issues — Put in the spec
• Main hall floor — Area, tone continuity, polish/honed — Variety, lot range, module, joints, finish
• Entrance / outdoor-air intake — Moisture, slip, sand abrasion — Finish (honed, brushed, etc.), mats, granite where needed
• Elevator hall / corridors — Traffic, wear — Thickness, finish, joint pattern
• Walls / feature walls — Visual impact, bookmatch — Slab layout, support, joints
• Reception tops — Edges, cutouts — Thickness 20/30 mm, reinforcement, finish

Decide early whether reception and the main hall share one slab lot, or whether the floor stays quiet while only walls carry dramatic veins. “All white lobby” alone splits procurement and fabrication later. In atriums with tall ceilings, wall veins read as visual “noise” before the floor does—so teams often limit feature-wall area and hold the rest to a calmer tone. Share area and a zone sketch via Contact, and we can align stock and delivery feasibility first.

2. Finish, Slip, and Circulation — Do Not Spec “Polish Only”

Finish is a safety and maintenance specification item, not only aesthetics. Polish gives strong mirror reflection and helps lighting, but many combinations lose traction when wet. Honed, brushed, and leathered families often show less scratch and etch, with better foot grip—common at entrances, café adjacencies, and umbrella zones.

Split sentences in the documents, for example: “Main hall floor: polish, dry interior use” / “Entrance 3 m and exterior-door frontage: honed or textured, with mats.” If the owner insists on polish everywhere, leave risk disclosure and zone exceptions in writing. Cart-wheel and sand-heavy paths rarely survive on marble alone; review granite or high-wear stone bands at the entrance.

Add one maintenance line to the spec: neutral detergent, entrance mats, sealing cycle (varies by variety and use; periodic inspection is shared). Approving “looks only” without cleaning standards leads to gloss banding within one to two years. Where night crews use acidic or alkaline cleaners, hand prohibited chemicals and approved products into the FM documents.

Lighting exaggerates veins and joints on polish. Approving samples under showroom spotlights alone can misread the lobby’s dimming and indirect light—review once more under actual site illuminance.

3. Thickness, Module, and Joints — Lock the Numbers

Commercial lobby floors vary by project and method, but many sites start around 18–20 mm. Wall panels may run thinner depending on load and support; reception and stair details often use 20 mm, 30 mm, or laminated edges. Prefer stated dimensions, tolerances, and calibration over “about 2 cm.”

Align modules (tile / cut sizes) and joint widths (e.g., 1–2 mm precision, or field allowance) with the drawings. On large areas, drifting modules accumulate pattern direction and diagonal error. Agree structural and fit-out methods—loading, levels, adhesive, or dry support—so they do not conflict with the stone supply spec. Reception zones with many penetrations for plumbing, heating, or embeds need cutout allowances and reinforcement on drawings to cut fabricator rework.

4. Put Lot, Attic Stock, and Dry Lay Into the Spec

On large lobbies, the same commercial name from a different production batch can break tone even at a distance. Safeguard the documents with: “same quarry / same production lot (or approved bundle range),” “full-face wide-shot and dry-lay approval before cutting,” and “attic stock 10–15% (breakage and future repair).” For phased work (phase-1 lobby → phase-2 expansion), write attic quantity and storage conditions as well.

Incoming inspection is a separate issue. For paperwork, labels, and damage records, use the slab delivery and receiving checklist. Bundle photos before factory shipment and post-delivery field inspection are both required. MarbleBest can consult at lot level when you share area and preferred tone. → Products · Contact

5. Lobby Spec Checklist (Copy Into Bid Docs)

Check the following in procurement and tender documents.

1. Zone map: floor / entrance / walls / reception / halls

2. Commercial variety name + approved sample and photo range

3. Finish (by zone) + slip and moisture conditions

4. Thickness, module, joints, pattern direction

5. Lot / bundle unity and dry-lay approval

6. Attic-stock ratio and storage

7. Sealing, cleaning, mats, and maintenance responsibility

8. Lead time, phased delivery, and alternate-lot approval process

FAQ

Q. Can we use only polished marble throughout the lobby?

A. It is common on dry main halls. Entrances, outdoor air, and wet zones are better split to honed/textured or wear-resistant stone for slip and gloss wear.

Q. What floor thickness should we write?

A. 18–20 mm is a common starting point, then confirm by stone type, module, method, and load. Include tolerance and calibration in the spec.

Q. Why is attic stock 10% or more?

A. For transit and fabrication breakage, and for tone-matched repairs years later. Large, long-life lobbies often target closer to 15%.

Q. Where should we use granite instead of marble?

A. Entrance bands, cart paths, and elevator halls—zones with heavy wear and moisture—are common places to split roles in practice.

Q. What materials do you need for an estimate or consultation?

A. Zone areas, drawings or sketches, preferred variety and finish, construction schedule, and approved sample photos are enough. → Contact
