Not all of the components I ordered came with instructions. Notably the pop-up waste for the sink ... which leaked quite badly until I dismantled and reassembled it with silicon applied to the underside of the sink (a lucky guess). Also I found that where supplied, the instructions were often poorly translated and lacked technical detail such as the correct size of fittings required to connect the component to the plumbing system, which made ordering the fittings difficult. Another annoyance is that during the online order process, upon adding the sink/vanity unit to the basket, the website suggested I would need to also order a separate set of basin wall fixings, which I duly added to the basket. In the end the extra fixings were not needed so now I have to faff about with sending stuff back for a refund.
