Recesses in the wall to get that toilet paper roll out of your way and free up much-needed space. You can easily replace that rusted old chrome unit with a newer, more modern, and stylish version. But this one actually recesses the roll. Must have standard 2 in. x 4 in. walls. Anti-microbial additive in plastic helps to keep the spread of germs down. Works easily with both single and double-size rolls. Will not work with mega and jumbo size rolls. Includes white plastic spring-loaded toilet paper roller. Installation could not be easier. Just cut the opening in the drywall, use construction adhesive on the back side of the frame, and push it into the wall. Measures 6.5 in. x 6.5 in. Your Rough opening needs to be 5.5 in. x 5.5 in. x 3.5 in., so it will work to replace most chrome metal units without enlarging your opening.
