Korea's apartment-reconstruction boom is forcing developers to shave weeks off bathroom MRO schedules. This guide explains how a tier-1 Korean engineered-stone supplier delivers custom shower panels that compress installation from five days to one, lock in 15 % material savings, and satisfy K-BUILD fire codes—without inflating SKUs.

Tile work on a 40-unit pilot in Gangnam required nine trades and 14 QC touch-points; switching to prefabricated engineered-stone bathroom walls cut labor by 42 % and eliminated grout-related callbacks. For retailers or commercial developers, fewer trades shorten the critical path and accelerate hand-over, generating interest savings starting at KRW 3.8 million per floor (Korea Development Industry Report, 2023).
Korean B2B building materials must clear two hurdles: K-mark fire grade B1 and ≤ 0.3 % water absorption under KS F 4739. Our manufacturer extrudes a 6 mm aluminum-stone composite that achieves 0.1 % absorption and Class A2, allowing hotels to market “non-combustible bathroom zones” to insurers for a 5 % premium rebate. Spec sheets are downloadable in Korean and English, enabling overseas procurement teams to validate data before RFQ.
Send 2D drawings or a Revit RFA; our Pyeongtaek factory CNC-cuts panels within 72 h, edge-routes faucet holes, and laser-etches serial QR codes for site traceability. A 2,000-panel order (≈ 350 en-suite bathrooms) loads Friday and arrives in Busan the following Wednesday—15 calendar days door-to-door, 40 % faster than Qingdao competitors quoting 25 days. This velocity lets project managers absorb last-minute owner changes without revising the master schedule.
Luxury condos in Haeundae sell faster when model units display marble-look engineered-stone cladding under warm 3,000 K lighting. We stock Calacatta, Travertine, and Basalt finishes on identical substrates, so purchasing teams hold one part number yet deliver three interior moods. Daewoo E&C records an average sales-price premium of 2.3 % per pyung—enough to recoup material cost before move-in.
List price: USD 58–68 per m² EXW Pyeongtaek, MOQ 300 m². Factor in an 8 % Korea FTA duty saving when re-exporting to the US or EU, and landed cost beats Spanish quartz by 11 % (Korea Customs Service, 2024). Request our Excel landed-cost calculator; enter CFR your port and you will see a 15–18 % gross margin even after a 5 % distributor rebate—sufficient for post-installation service reserves.
