Hi! Thanks for the reply.
The wood flooring is engineered white oak.
...and I don't know if it needs an expansion gap. I think we were just planning on a small gap under the base around the perimeter of the rooms. Our condo is pretty small 15' x 30' (x3 floors) so there aren't a lot of large expanses of wood. 4 transition strips needed for the door thresholds of our bathrooms (3). Other than that, we were just going to run the wood lengthwise thru our condo (structure runs the short way).
Interesting floor plan, 3 floors, one bath on each floor, and 450 sq ft (15' x 30') on each floor. Are you planning to install flooring throughout the condo on all three floors?
Have you determined which way your floor joist run? When you say the structure runs the short way, are you referring to the direction of the floor joist? If so you're good on installing the flooring length ways, or perpendicular to the joist.
I am familiar with the Schluter L channel molding and there are other manufacturers of similar moldings. This type of molding is designed to be set in thinset and go under the tile, to dress and protect the edge, between different floor coverings. It doesn't provide an allowance for expansion, nor for differences in floor heights. In your case, and I am assuming the tile is already laid, there is really no practical way to retrofit it under the tile without risking breaking an edge of the tile.
What is the thickness of the wood flooring and do the bath floors match heights?
Where you have to be most concerned with expansion is along the width of the installation. There are many types of wood transition moldings that allow for height differences and for expansion. And there is always the option of modifying a ready made piece, or making your own from scratch. White oak is a pretty popular species for flooring, you should be able to find something that works and is attractive.
