Walk into a converted Brooklyn loft or a French country kitchen and one detail likely catches your eye before anything else — a tight, geometric brick floor laid at 45 degrees, with the rich patina of clay underfoot. Herringbone brick flooring is one of the oldest interior floor patterns still in use, dating back to Roman roads, and it has come roaring back into residential design over the last decade. The look is unmistakable. The installation is unforgiving. Get either wrong and you have a five-figure mistake you cannot easily walk back from.
What Counts as Brick Flooring Today
True full-thickness clay brick at 2-3/8 inches is heavy and rarely used inside modern homes because it overloads floor framing. What most homeowners actually install is thin brick — clay or concrete pavers cut to 1/2 to 5/8 inch thick, sold in cartons of 60 to 90 pieces per 32 sq ft.
The dominant US suppliers are Glen-Gery, Old Mill Brick, McNear, and Belden. Pricing runs roughly $4.99 to $9.99 per sq ft for the brick alone, $1.50 to $3.00 per sq ft for mortar and sealer, and $7.00 to $12.00 per sq ft for installation labor. Total installed cost lands between $13 and $25 per sq ft.
Pros That Justify the Investment
Brick is essentially indestructible. Properly sealed clay brick will outlast the framing of the house it sits on. It is naturally non-slip — DCOF values for unglazed thin brick typically exceed 0.60, which clears the 0.42 wet floor minimum set by ANSI A137.1 for residential applications.
The herringbone pattern adds visual movement that hides scratches, dings, and minor color variations between bricks. It also reads more upscale than a basic running-bond layout, which is why high-end designers default to it for kitchens, mudrooms, and sunrooms.
The Cons That Catch People Off Guard
Brick is cold underfoot — colder than tile, concrete, or hardwood — so most homeowners installing it pair it with an electric radiant heat mat like Schluter DITRA-HEAT or Warmup DCM-PRO. That adds $8 to $14 per sq ft to the project.
The grout lines are also generous — typically 3/8 to 1/2 inch wide — which makes the floor harder to clean than smooth tile. Spilled red wine, coffee, or pet accidents wick into both the brick and the mortar joints. A penetrating sealer like Miracle 511 Impregnator or Aqua Mix Sealer’s Choice Gold helps, but you will need to reseal every 18 to 36 months depending on traffic.
Subfloor Requirements and Weight
Even thin brick at 5/8 inch weighs roughly 5 to 6 lbs per sq ft installed. That is manageable on a slab-on-grade or a properly framed first floor over a basement, but it is a real consideration on upper floors. A typical 2×10 joist system at 16-inch on-center can handle this, but check your joist span tables or have a structural engineer review for spans over 14 feet.
The subfloor needs to be flat to 1/8 inch over 10 feet — tighter than the 3/16-inch tolerance for vinyl click-lock — because brick does not flex. Over wood subfloors, install Schluter DITRA or USG Durock NextGen cement board with thinset to create a stable, decoupling layer.
Installation Method, Step by Step
A clean herringbone brick install takes 2 to 3 days for an average 200 sq ft kitchen with two installers. The process:
- Snap a 45-degree reference line from the room’s centerline using a chalk line
- Dry-lay a 4-foot by 4-foot section to confirm pattern alignment before applying mortar
- Spread a 3/8-inch notch trowel layer of unmodified thinset for clay brick or modified thinset for concrete brick
- Set each brick with a 3/8-inch tile spacer, working from the centerline outward
- Let the thinset cure 24 hours, then grout with a sanded grout matched to the brick tone
- Seal with two coats of penetrating sealer after the grout cures 72 hours
Cuts at the perimeter are made with a wet saw using a continuous-rim diamond blade. Plan on roughly 12 percent waste — significantly more than the 7 to 10 percent waste you would budget for a straight-lay tile install.
Sealing and Long-Term Care
Unsealed clay brick will absorb water, oil, and stains within seconds of exposure. The minimum protection is a penetrating sealer applied immediately after grout cure. For high-stain areas like kitchens, layer a topical sealer like Stonelock Pro-W or Stonetech Surface Sealer over the penetrating coat for a slight satin sheen and a wipeable finish.
Day-to-day cleaning is just a soft broom and a damp microfiber mop with a pH-neutral cleaner like Aqua Mix Concentrated Stone & Tile Cleaner. Skip vinegar — its acidity will etch the mortar joints over time.
How It Compares to Lookalike Alternatives
If you love the look but not the price or maintenance, porcelain tile manufacturers like Marazzi, Daltile, and Florim US all make brick-look porcelain in 2-by-9-inch and 3-by-12-inch formats. Installed cost lands at $9 to $15 per sq ft, the porcelain is stain-proof out of the box, and you still get the herringbone geometry. The trade-off is the texture — porcelain reads convincingly from 6 feet away but never quite matches real brick up close.
For a budget herringbone option, brick-look LVP from COREtec Originals or Karndean Art Select runs $4.99 to $6.99 per sq ft, installs floating over most subfloors, and looks credible in dim or warm-lit spaces.
Who Should Actually Buy It
Real herringbone brick is a forever-floor choice. It makes sense for mudrooms, entryways, kitchens in historic or farmhouse-style homes, and any space where heat retention is a feature rather than a bug. It does not make sense in cold-climate basements without radiant heat, upper floors with marginal joist spans, or for homeowners who hate resealing floors every couple of years. Match the floor to the lifestyle, and brick rewards you for decades.
