Yes. A heated towel rack can often be installed on tile, drywall, or wallpaper, but the finish itself is only part of the answer. What matters more is the wall structure behind that finish, the mounting approach, and whether the installation is being planned appropriately for the room.

In many installations, wall backing is one of the most useful things to plan for. A heated towel rack is a functional wall-mounted fixture, so it should be supported properly rather than treated like a lightweight decorative piece.

This is not a question with one universal measurement. The right answer depends on local code, the exact room conditions, the collection being installed, and whether the location is simply near a shower or tub or part of a true wet-area condition.

The best place to install a heated towel rack is not the same in every bathroom. The right location depends on the room layout, the collection being installed, how the rack will actually be used, and any code or electrical restrictions that affect placement. The goal is to balance convenience, safety, and room fit rather than chase one fixed wall or one fixed distance from the shower.
