The Vellamo Single Bowl Plumbing Kit is perfect to use with your 1 bowl kitchen sink. It has connections for washing machine and dishwasher, and can be used with 40mm or 43mm pipes. If you'd rather not take up the entirety of the space underneath your kitchen sink with pipework, there is a Space Saving Single Bowl Plumbing Kit also available. This lets you keep most of the cupboard space which is ideal if you have a boiling water tap, filtered water tap, or just a lot of cleaning products. If you have a 1.5 or 2 bowl sink then you will need the Vellamo Double Bowl Plumbing Kit.
