Panel design 1.5 bowl kitchens sinks. The Alea bowl and a half sink are perfectly suited in the modern day kitchen. A crisp machined edge draining board gives this sink an up to date look, making it ideal when style and functionality are a priority. High edges stop water overflow, preventing damage to the carcass below the sink and to the worktop surrounding it. Like all our Pyramis range, a 25 year warranty comes as standard. A smaller single bowl version is also available.
