I had the same problem with my JRT/Pug mix, Duncan. He would go to the bathroom in his crate. I thought that maybe I wasnt giving him enough space, so I tried giving him a penned in area in the kitchen. Well, that was even worse because he would go and then smear it everywhere. I believe that this was because when I rescued him he had been in a crate 24/7 and never had a choice on where to go to the bathroom, so he thought it was okay.
Although it may be discouraging it took about 4-6 months for him to grow out of this habit, and he still is not 100% house trained. I still need to leave him in his crate when I leave the house and he can never be unsupervised. There are times when he will still go in his crate, maybe once a month.
My best advice to you would be to make sure that when the dog goes to the bathroom outside to reward it immediatly. Make sure you have treats in your pocket when you bring it out. Eventually it will learn that this behavior is rewarded. Also, make sure that you have the dog on a regular schedule. Feed the dog at least a hour before it is crated and take it out right before you are about to leave.
I hope that this helps! I understand completely what you are going through!
