If your wall is solid, rather than a partition type of material, then bolting the enlarger column to it will work very well. Some enlarger manufacturers sell them. They generally consist of a substantial angle wall bracket to which the column bolts and a second lighter stabilising bracket that fixes the column top to the wall. Some sort of mechanism to adjust the setup is incorporated also. Provided your wall is not subjected to vibration then this is the way to go. That's not to say that the base board can be left to rattle about. It's obviously got to stay aligned during exposure.
