Brand new Rosa branded corner basin bought 4 months ago for my apartment in advance. After my apartment completed, plumbers said that this can’t be fitted as the drain pipes are not aligned properly. And sellers said that they can’t exchange as it’s over 2 months. There are some workaround with the basins. But I want an well fitted basin. In my bathroom. But maybe in your case you have well organized drain pipes and the corner basins will fit in your bathroom.
