The sink & faucet are both sold seperately from Ikea. In fact everything you see here is from Ikea. These components were utilized at the request of my customer. If you are considering this sink as part of a DYI project let me know and I will give you some additional information that may be helpful.

I'd like the additional info...great sink

First let me say I was quite impressed with the overall quality of the sink, particularly for the price. That being said I was somewhat perplexed by the almost total lack of instructions. The sink has finished edges on all four sides. This is great if you happen to be using it in a stand alone application but I found it less than desirable for a built in application. The counter tops are Ikea as well, also well constructed but there was really no way for the sink to fit into the counters except to simply end butt them, not ideal for a potentially wet location.
The tops are purchased in premade lengths with both ends finished. I cut the tops so that each ends adjoining the sink had a factory finished end.
The sink comes without any hole(s) for a faucet. This would be fine if you have an application where the faucet can mount into the counter or wall in lieu of the sink but one would think with a sink like this you would almost always be mounting the faucet into the sink itself. I guess they design the sink like this so it can adapt to a variety of applications. The funny part is Ikea is all about DYI. Drilling a hole into this sink for a faucet is not a easy DYI project. You will need a high quality Unibit step drill bit capable of drilling a 1 3/8" hole. This will set you back about $50. The under side of the sink has wood blocks for mounting, quite solid for screwing it down but they seemed to be in a less than ideal location in relation to the cabinet configuration.
In case you're interested in the faucet as well, it's built like a tank and also reasonably priced. It does however require that you provide support via a wall mount bracket. The faucet comes with the bracket and a variety of adaptors for different positions away from the wall.
I was happy with the end results but I wouldn't reccommend installation by a novice DYI'er.
Good luck...
