The Linear Drain made to be used indoors, comes in different widths and lengths that can be cut down to the width and length of what you need in a home shower. It is similar to the outdoor drains only in a smaller model as showers do not need the drainage that outdoor drains do. My drain cover and insert had to be cut down to a custom size about 37". It, too is a removable grate so that I can clean the standard round drain beneath it.
