Dark Walnut Rio Interior Door

Dark Walnut Wood Interior Doors

When drama is what you're after, go for this interior door in dark walnut. The grain design forms sharp angles at the center of the door for a look that takes center stage in a room. This is the door you want to use for a grand entryway into a living space or a commercial or office space.

As with all of our interior doors, we utilize only the best quality veneer, imported from Italy. The dark walnut veneer is exceptional for its durability and its color, a high contrast dark brown with red and sometimes golden casts. The grain is dark brown to almost black.

While this door could be used as a single or paired with another to form a striking entryway, it can also be used in combination with our other dark walnut interior doors such as our flush vertical or flush horizontal doors. All doors and orders are customizable.
