Frameless Interior Doors
Frameless interior doors sit flush with the wall for a clean, trimless look, using concealed hinges and an invisible frame — a minimalist, modern statement.
What “frameless” actually means
A frameless (invisible) door sits flush with the finished wall. The jamb is recessed or covered so you see a continuous plane instead of casing. Concealed hinges carry the leaf; the reveal around the door is a hairline, not a traditional architrave.
That look needs a square opening, a consistent wall finish to the edge, and a slab thickness that matches the hardware kit. If the wall is already finished with thick casing you like, a standard prehung swing is usually the better buy.
