my bathroom sink (installed 2017) was broken recently and needs replacing. on inspection there is no brand name and only a few markings so I'm guessing its a trade sink that plumbers would buy. The sink has 1708 indented in the china which i guess is a model number but doesnt show up on google. The main marking RR is located near the drain pipe hole, i think this might be the brand identifier. The sink itself is a white semi-recessed sink approx 495*395. Main distinguishing feature is the recessed area under the taphole, i have been googling sinks and cant find another sink with a partial recessed area like the one i have. Does the sink or the brand marking ring a bell with anyone, it would help me a lot if it did, thanks for your help
