Not sure where you are located, but a pre-built one will range from 600-3,000 based on those dimensions. They include the stone, and the sink, so you wouldn't have to incur additional costs. Sometimes, they may even include the faucets, but they are typically Chinese faucets and pretty Blah.

Custom Built ones, can be double or sometimes maybe even triple that price, for just the cabinet. You would need to buy your own sink, and unless you have extra material left from maybe your kitchen, you would need to purchase a full slab of stone for your vanities. Some places sell half a slab, and some stone fabricators may sometime have extra left over material, which they may sell to you. Now, you must also factor in that the cost of fabricating and installing this stone will be added on to this too.

If you're on a tight budget, pre-built may be a solution. If later on (like in 5 years) you get more money, or bore with it, you can rip it out, and do your custom one.

Now, if this is your dream home, and can afford to go custom, I highly encourage you to do so because the quality, your specifics needs, and finishes are catered to you.

Are you in south Florida? If so, I can suggest a place that has nicer vanities you can actually go see..

We have a showroom in Ft. Myers - Stop in and talk to a Sales Consultant, they are very helpful and will assist as much as they area able. The address is 10994 Metro Parkway.

Pre-built meaning what?

Unless you're going to be moving soon, use something else. The pre-packaged stuff from the big box stores all come from China. It won't hold up well past about three or four years down the road.

Glad to help. Good luck with your new home!
