To choose porcelain flooring well, forget colour first and match three technical variables to how each room actually lives: foot traffic, moisture and slip resistance. A living room wants warmth and large formats; a Mallorcan terrace needs frost-proof 20 mm and an R11 rating that grips in the rain; a bathroom needs a non-slip surface underfoot. At Gomila Cerámica, distributors in Mallorca of brands like Kronos, Ragno, Inalco MDi, Keope, Coem and WOW, we ground that choice in the numbers: absorption ≤0.5%, PEI II-V, R9-R11 slip classes and 9, 12 or 20 mm thicknesses. Here is the room-by-room guide.

Which three factors really decide the right porcelain?

Always weigh three figures before colour: abrasion resistance (PEI I-V), moisture behaviour (water absorption) and grip (slip resistance R9-R11). PEI measures traffic the glaze withstands (bedroom II-III; kitchen and shop IV-V). Absorption decides wet and outdoor suitability (technical ≤0.5%, near-waterproof: prevents stains, mould and frost cracking). Slip resistance governs safety (R9 dry interiors up to R11 outdoors, showers and pools). Add thickness: 9 mm standard interiors, 12 mm reinforced large formats, 20 mm outdoor with no groundwork. Explore the full range of porcelain flooring we carry.

Which porcelain flooring for the living room?

Large-format wood or stone effect, PEI III-IV, matt: warmth, continuity and daily durability. Large formats (120, 160, 180 cm) cut grout and create space. The wood effect of Kronos Les Bois (Cobolo, Bocote, Mogano, Slavonia; up to 180 cm; herringbone Chevron or continuous plank) brings warmth with no upkeep. For a mineral language, a limestone effect in the large slabs of Inalco MDi (1600×3200). Absorption ≤0.5%, PEI III-IV and matt: the winning combination.

What should kitchen porcelain prioritise?

Resistance: PEI IV-V, absorption ≤0.5% and a forgiving finish (stone or cement effect). PEI IV-V survives traffic and moving furniture; cement and stone effects hide footprints and crumbs. Ragno RealStone (Ceppo di Gré) and Coem surfaces deliver contemporary character with durability. For kitchens open to the living room, one format unifies. Interior-exterior flow: same series in 9 mm inside, 20 mm out. An R10 adds grip.

How do you choose non-slip bathroom porcelain?

R10-R11 in the shower and a marble or stone effect for the rest: wet-surface safety is the absolute priority. Reserve R11 (R10 minimum) for tray and splash zones. A marble effect brings serene elegance: Inalco MDi Lyra (Polished Honed) or Petra (irregular-veined limestone) in large formats with minimal grout, ideal for continuous floor-to-wall wet rooms. Absorption ≤0.5% makes it immune to humidity, no sealing. For walls and niches, the zellige and reliefs of WOW (Bejmat, ENSO) add artisanal contrast.

Which porcelain brings warmth to a bedroom?

Warmth and comfort over extreme resistance: wood-effect PEI II-III is plenty (low traffic). Kronos Les Bois in cosy tones (Mogano, Sarawa), never scratching or fearing moisture. PEI II-III suffices; a natural matt finish avoids glare. If it connects to an en-suite, carrying the wood effect into both — stepping to R10 only in the wet zone — creates elegant continuity.

What do hallway and entrance porcelain need?

Max traffic: PEI IV-V and, ideally, full-body. Abrasion resistance is non-negotiable; full-body (colour through the body) barely shows wear if scratched. The technical collections from Keope are built for this. An R10 adds safety against wet soles. Mid-tones and stone or cement textures hide dust better.

Which porcelain for a terrace or outdoors?

In Mallorca: 20 mm, R11 and absorption ≤0.5%. The 20 mm allows installation with no groundwork over pedestals or gravel and carries loads; near-zero absorption makes it frost-proof (no absorbed water, no freeze-thaw); R11 grips in rain or beside a pool. Les Bois 2.0 from Kronos takes the wood effect outdoors at 20 mm; RealStone Ceppo (XT20) from Ragno offers Ceppo di Gré stone. For continuity, the same series in 9 mm indoors: the threshold vanishes.

And for a high-traffic commercial space?

Maximum wear: PEI V and full-body technical porcelain. Only PEI V guarantees endurance against hundreds of footsteps, trolleys and dragging; full-body ensures imperceptible wear. Keope and Coem cover this segment with large formats. Match slip (R10-R11 in hospitality and entrances) and consider 12 mm in point-load areas.

Conclusion

Choosing porcelain flooring well means listening to each room: how much it is walked, how much water it takes, and what safety it demands. With those three figures — plus the right thickness — the aesthetics take care of themselves, because today’s porcelain imitates wood, marble, stone or cement with astonishing fidelity and a durability no natural material can match. At Gomila we carry the brands that cover every scenario. Browse our porcelain flooring to begin.

Frequently asked questions

  • What does PEI mean? Glaze abrasion resistance (I-V): II-III bedroom and bathroom, IV kitchen and living room, V hallways and commercial.
  • What slip resistance do I need? R9 dry interiors; R10 kitchen and bathroom; R11 (Class 3) shower, pool and outdoor.
  • Why 20 mm outdoors? Mechanical strength for a raised install plus frost-proofing via ≤0.5% absorption.
  • Same floor inside and out? Yes: the same series in 9 mm interior and 20 mm R11 exterior; the threshold disappears.
  • Does it need maintenance or sealing? No: ≤0.5%, waterproof, cleaned with neutral products; resists stains and household chemicals.
