Do not buy anything that doesn't come as a complete package as the customer service is 1 star for actually replying to my complaint but not being prepared to do anything. We ordered a vanity unit including sink clicking on all the drop down options. Obviously have to order a tap separately which comes with it's waste. But the waste was too short on thread to fit the sink. We had 3 units and taps and had to waste time and money while the plumber purchased 3 "normal" wastes. QS wouldn't refund the difference, parroting they "don't offer advice" there was nothing on the sink or tap specifications to suggest an issue. Worst service I have had.
