I am tiling a new bathroom and would like tile right up to the door casing on both sides of the door. The door isn't installed yet. Should I install a prehung door and the casings before proceeding? Or is there an easier way.

Will the finished tile be the same height as the floor on the outside of the bathroom?
Generally you want the door jamb and casing - both inside and out - to touch the finished floor.
Often you have to undercut one or the other of them.
They sell what they call a jamb saw for that.
$20 or so from many big box stores or online online sources.

Yes the finished tile floor will be very close to the hardwood flooring outside. But I cannot say for sure. 1/8 -3/16 variance. I'll check out the jamb saw.

Tile first, set the jamb on top of the finished floor after.
I agree with that, but for the wall tile, I need something to tile up to. In this situation, it would be the casing. So I'm in a bit of a pickle.

Mock up a door frame and trim, draw a line along the edge of the trim to show where to stop the tile, then take down the frame and trim. After the tile is installed, when you put in the door and trim you can run a bead of silicone along where they meet.

We trim the house, then do the tile later.

Tile contractor uses a jamb saw to trim the door jambs at floor and just tuck under the finished tile taking his total buildup of the floor into account. Make sure they set their jamb saw properly or your caulk joint is egregious and correction involves replacing trim and possibly door jamb (been there....).

either way is fine.
no right & wrong way.
if you don;t have a jamb saw, hang the door up the thickness you need for the tile, plus a tad more . caulk the bottom with painters caulk after completed & it will be 100%

I'd install the door and casing before the tile but there is no right or wrong answer. I think it's easier to adjust the tiling with the trim installed.

Follow some of the above advise and pick who you want to make a repeat trip for a $ trip charge.

Do ceramic floor with no doors? Then trim carpenter comes back to set the door after the now tiled floor. Oh but wait, the tile contractor is also coming back now after the door is set since it wasn’t ready when he did the floor. So you have 2 charges!

Or you set the door, make smart decisions on jamb trim saw, then tile proceeds. No comeback, no trip charge. This is how it proceeds in production, and high end production for that matter.

Return trips everyone looses.

No you don’t die bullnose into door casing. You use a full tile and **** to casing and Schluter above as needed. Bullnose is yesterday’s technology today.

Good luck OP.

For the wall tile, in an existing room I pulled casing, rabeted the edge where it would meet tile, reinstalled casing, and then slipped tile behind casing. Looks better to me than a caulked joint, more like a tile wall than a tile covering.
