Amid rising French marble prices and the looming 2025 ERP standards, boutique hotels and property developers are looking for a hand-washing solution that is both chic and cost-effective. This guide explains why the engineered-stone basin is becoming the go-to B2B option for delivering 50-plus bathrooms on schedule—without exceeding the tile budget.

Major French accounts (Accor, Vinci Immobilier) require a CAC below €380 per bathroom. With a density of 2.3 g/cm³, the solid-surface bathroom sink weighs 40 % less than 30 mm stoneware, cutting handling and freight costs. Add ISO 4892-2 UV resistance and you secure a 14-month ROI on a 3-star hotel in Provence-Alpes-Côte d’Azur.
The label demands 20 % reusable material. Our alumina-trihydrate blocks contain 35 % recycled aggregate, certified by the CSTB. By integrating a made-to-measure engineered-stone vanity top (radius 320–1,200 mm), a Lyon developer earned five bonus points and sold units 7 % above the Confluence district average.
1. NF-EN 14688 certification plus AOC Bordeaux red-wine stain test.
2. MOQ ≤ 30 pieces with 15-day lead time via Sète–Barcelona port.
3. 10-year warranty including on-site re-polishing, avoiding costly CEX.
Check the laser-etched batch number; it ensures traceability and reverse logistics compliant with the AGEC Act.
Pre-cut 35 mm tap holes at the factory, apply MAPESIL LM silicone sealant 24 h before delivery, and the engineered-stone countertop basin drops in without a metal leg. Result: 32 extra bathrooms delivered each week, saving €120 k in annual labour on a 300-unit housing project in Lille.
According to Statista Décision BTP, 63 % of French interior architects plan to increase solid-surface wash-basin usage by 25 % in senior residences by 2026. The market is forecast to grow from €148 m to €197 m, driven by energy-efficiency retrofits and the mandatory Italian-style accessible shower.
