Walnut Ontario Flush Interior Door


Simple yet elegant, this flush door is ideal for using throughout a house, apartment or office. It features a slight change of grain that lends a paneled door look while maintaining a flat plane throughout. Ingenious - and very modern!

The wood used in this interior door is walnut, a classic hardwood prominent in North America and parts of Europe. Walnut is exceptionally durable - it will last for years in your home - and has a rich dark coloring that ranges from dark golden brown to near black.

Use this door for closets, hallways, bedrooms, bathrooms, utility rooms and living areas. For a change of pace, use one of our more elaborately patterned walnut doors or a glass door in special entryways such as a foyer or patio.
