National affiliates and production centres are now active in four continents. The distribution network is located in 135 different regions of the world, and 71 production plants are located around the world, employing 20,200 employees. The musician brand was created in 1917 with the company compañía roca radiadores, based on a factory in gavà, near barcelona, which specializes in casting iron heaters for home heating systems. However, with the rapid success of new products in the market and the growing desire to expand, companies have expanded their business niches by targeting diversification. In 1925, roca launched the cast iron tub. In 1936, musicians officially joined the ceramics bathing industry, and in 1954, musicians came out with new money. In 1962, musicians opened a second ceramic factory in alcalá de henares, madrid. In 1963, with the official launch of the air conditioning machinery plant in sabadell, barcelona, musicians became spanish enterprises entering the emerging air conditioning market. Five years later (1968), musicians opened a third ceramic factory in alcalá de guadaira (seville) and a steel tub factory in 1974. In the 1980s, companies began to enter the tile field. The establishment of cerámicas del foix, a subsidiary of the flag, marked the official launch of the tile business. In 1989, the company acquired a portuguese cleaning plant. According to the development strategy, the companies created several sales subsidiaries in the last 80th century and in the 1990s, merged several market-driven enterprises and carried out a number of acquisition and business alliances. In 2002, the musicians reorganized their groups, dividing the different fields of business into separate companies. As a result, a new holding company, roca corporación empresarial, was formally established. In 2005, the company sold heating and air-conditioning operations to focus its attention on the field of bathing, and by that time the transformation process of the company had officially come to an end; early in 2006, the company's bathing operations had gained global sophistication. The musician is a fully-owned spanish enterprise, and the capital of the company is owned by the founding family。
