Product Overview
Florim Matières Brun 24" x 48" Porcelain Slab Tile (60 cm x 120 cm) is an architectural Italian porcelain slab manufactured by Florim (part of the acclaimed Matières de Rex collection). Inspired by raw concrete, troweled cement, and patinated natural stone, the Brun colorway offers a sophisticated, earthy palette of warm taupe-brown, soft mushroom grey, and muted clay undertones with subtle organic variation.
Finished in Florim’s refined Matte (Mat/Naturale) surface, this 24x48 large-format slab (~8 sq. ft. per panel) delivers a grounded, tactile visual with low glare and certified foot traction. It provides a continuous, warm concrete-and-stone field with minimal grout interruptions, making it ideal for primary bathroom floors, full-height shower feature walls, open-concept living floors, fireplace surrounds, and commercial interiors.

Recommended Applications
-
Main Living & Entryway Floors: Creates an expansive, warm neutral taupe field across open-concept floor plans without reflecting harsh light overhead.
-
Master Suite Bathroom & Shower Walls: The Matte (Naturale) surface provides certified foot traction under wet conditions (R10 / DCOF ≥ 0.42) for bathroom floors, while creating a seamless, spa-like feature wall inside full-height shower enclosures.
-
Fireplace Surrounds & Feature Breasts: Non-combustible vitrified porcelain resists thermal shock and high temperatures without staining, fading, or cracking over time.
Installation and Handling Guidelines
⚠️ CRITICAL WARNING: LARGE-FORMAT SLAB PROTOCOL
-
Leveling Clip System Required: Installers must use a mechanical tile leveling clip system along joint lines during setting to pull adjacent slab edges flush and eliminate lippage across 48-inch spans.
-
Thinset Mortar Selection: Set using a high-performance, polymer-modified Large & Heavy Tile (LFT) thinset specified for porcelain slabs (ANSI A118.4 or ANSI A118.15 like MAPEI® Ultraflex LFT or LATICRETE® Multimax Lite).
-
Mortar Back-Butter Technique: Comb mortar directionally on the substrate AND back-butter each 24x48 panel to guarantee 95%+ solid mortar coverage indoors and 100% coverage in wet shower zones.
-
Running Bond Offset Rule: If installing in a staggered layout, TCNA standards recommend offsetting joints by no more than 33% (approx. 16 inches) rather than a 50% half-brick bond to minimize tile bow lippage.
Professional Recommendations
-
Dry Lay & Shade Blending: The Matières Brun graphic carries natural mineral shading (V3 rating). Unbox and dry-lay slabs from multiple cartons before setting to randomize taupe, grey, and clay tones across the layout.
-
Grout Color Strategy: Pair with a warm taupe, light greige, or medium grey high-performance grout (such as MAPEI® Ultracolor Plus FA in Warm Gray or Taupe) to make tile joints blend into the floor field.
Care and Maintenance
-
Routine Cleaning: Clean easily using warm water and a neutral pH porcelain floor cleaner. The non-porous matte surface naturally resists foot traffic marks, water spots, and soap scum.
-
100% Acid & Stain Proof: Impervious vitrified porcelain stoneware (< 0.08% water absorption) protects against oils, wine, cosmetic acids, and household cleaning chemicals.
-
Zero Sealing Required: Unlike real concrete or natural porous stone, glazed Italian porcelain is non-porous and never requires sealers, topical waxes, or special impregnating treatments over its lifespan.
Design Profile
-
Aesthetic Inspiration: Warm Minimalist, Japandi Spa, Industrial Chic, Modern Organic.
-
Visual Synergy: Pairs exceptionally well with warm walnut, natural oak, or bleached ash millwork, brushed brass, matte black, or brushed nickel fixtures, and white or cream quartz surfaces.
-
System Cohesion: Designed to coordinate directly with smaller formats (Florim Matières Brun 12x24), companion colors in the Matières collection (Saintonge, Nuage, Mou, Barrique), and matching outdoor Grip finishes.
Frequently Asked Questions
What is the color profile of Florim Matières Brun?
Brun is a warm, mid-tone taupe brown with subtle mushroom-grey and clay undertones. It offers a softer, warmer alternative to cold greys or dark espresso shades while maintaining a contemporary concrete-stone texture.
Is Florim Matières Brun 24x48 suitable for shower floors?
While excellent for main bathroom floors and shower walls, standard shower pans with central point drains typically require smaller mosaics to conform to multi-directional slopes. However, 24x48 tiles work exceptionally well on shower floors utilizing linear trench drains.
Does this concrete-look tile require sealing?
No. Vitrified porcelain from Florim is non-porous (< 0.08% absorption) and completely impervious to water staining. It requires zero sealers, waxes, or special protective coatings.
