Depending on the context "want" can be similar to "want to" (싶다). But there is an actual verb, want , 원하다. I always want something new, 나는 언제나 새로운 무엇을 원한다. Just compare this to, I want a shave (I want to shave). We can use 싶다. 면도하고 싶다.

To want in korean is 고싶어요, 요 here is to make the speech formal : I want to go to school = 학교에 가고 싶어요 I want to eat Kimchi = 저 는 김치를 먹고 싶어요 And for the negative "I don't want to..." we say 고 싶지 않아요 I don't want to go home = 집에 가고 싶지 않아요 I dont want to watch tv = 저는 텔레비전을 보고 싶지 않아요 I hope this will help, i just learned that from a friend ^^
