The work consists of removal and demolishing the old bathroom and preparing new water, sewage, and electrical installations. Then, the walls and floors will be levelled and primed for waterproof insulation (tanking) in wet zones. The next phase involves laying wall and floor tiles, grouting, and silicone sealing. Finally, the white assembly will be completed, including the installation of sanitaryware (WC, washbasin, shower/bathtub, faucets), lighting, accessories, and performing final operational tests.
