Flooring Tile - Tile around tub meets wainscot

I am in the planning stages of doing a tile job around a bathtub/shower. Around the edges of the tile, I plan to use some bullnose pieces where the tile meets the sheetrock wall. I would, however, like to install some sort of wainscot to the walls. Perhaps beadboard, that's what my wife likes. I am not sure how these will come together. If I simply butt the beadboard up against the bullnose edges, that wouldn't look good. Is ther some other type of tile I should use for the edges that would allow for a nice looking transtion to the wall with the different thicknesses, one with wainscot and one without?
