I'd like to know the procedure for installing a bathroom floor thatwill grade to a floor drain without any enclosure. The project will of course see the whole room faced w/tile. I remember seeing this done in Europe but didn't really pay much attention at the time. It's a very small space and the exterior wall is hipped as it is on the second storey of a 1 1/2. There is a slight chance I could carve out some joist space as it is an old home with beefy floors. Any advice would be most appreciated

You need to build your own shower pan for the room. The old method was to hot mop tar then overlay with a mortar bed and tile. Modern construction uses a waterproof membrane, but is basically the same principal. I am going to refer you to an article by Tom Meehan that describes the construction, because it is a detailed process, and he really does it very well, and with easy to follow photos.

I suggest you not carve out any joists, and there is no need to disturb the subfloor. I have built showers that incorporated the angled roof between the knee wall and ceiling in a Cape style home with good success. It should not be a problem.

in my opinion the "old-way" (hot-mop) is by FAR the best way...erik
