Our solid Pine Colonial style interior doors radiate warmth and natural beauty. Now you can choose from two new styles with intricate design and detailing. The 2 Panel design with the arch and v-grooves on the face (shown above) give the doors an intricate, artistic style. The 6 Panel design gives the doors a clean, traditional style that will complement any decor. Both doors are incredibly durable, made of solid pine and are easy to install.
