Weil Gotshal & Manges, Clifford Chance (CC) and Linklaters have won key roles on Japanese bathroom fittings company Lixil's €3bn (£2.5bn) acquisition of German rival Grohe.

TPG Capital and DLJ Merchant Banking Partners, Grohe's private equity owners, are set to sell their 87.5% stake in the company to Lixil and the Development Bank of Japan in a joint acquisition structure.

The deal, which is expected to close in the first quarter of 2014, is the largest German investment made by a Japanese company to date.

Weil acted for Grohe with a team comprising Frankfurt corporate partners Gerhard Schmidt, Heiner Drueke and Stephan Grauke, as well as Munich corporate partners Thomas Schmid and Barbara Jagersberger on M&A and private equity matters. 

Munich partner Tobias Geerling and Frankfurt partner Juergen Borst were on the team providing tax advice. 

CC acted alongside Weil with a team that included Germany managing partner Andreas Dietzel and capital markets partner Markus Pfueller. 

Linklaters represented Lixil with a team headed by Duesseldorf corporate partner Klaus Marinus Hoenig and London corporate partner David Holdsworth. 

Other team members included Duesseldorf competition partner Carsten Grave, Duesseldorf tax partner Oliver Rosenberg, New York antitrust partner Thomas McGrath, London antitrust partner Nicole Kar and Tokyo corporate partner Hiroya Yamazaki. 

Lixil has acquired several companies in recent years, including its €575m (£480.35m) purchase of Permasteelisa's Italy operations in 2011. 

CC advised the buyer on the deal while Cleary Gottlieb Steen & Hamilton acted for the seller.
