Customers can either pick up their interior doors themselves or opt for delivery. When making the purchase, it's important to clarify all the details of the kit and the color. If the doors will be stored for some time after delivery, it's recommended to keep them horizontal in a closed room and in their packaging to protect the coating from sun damage. The doors should also be allowed to acclimate to their surroundings before installation, and any freshly processed edges should be immediately treated. It's also important to avoid significant temperature changes.

Customers can browse a catalog of interior doors on the Doors Plus Windows website to find a model that suits their interior design preferences. The site offers the option to purchase an interior door with a frame and all necessary accessories already assembled, and there is a wide selection of doors available to choose from.
