Thoughts on (Christian) alters in the home?

My church and the theology of my congregation preaches against them. Their are a lot of reasons why but one of them is that is promotes idolatry and having one specific place to pray when you should be able to pray anywhere at any time. But yet for some reason I feel compelled to have one in my home. I think it would be nice and a way for me to feel closer to the Lord and worship when I cant attend church.
