Choose one wide rail when you have a clear stretch of wall and everyone can reach it. Consider two smaller rails when towels need to be within reach of separate bathing areas or when a door or vanity breaks up the available wall.
Compare usable hanging positions
Measure the towels and mark out each arrangement on the wall. With one wide rail, try two folded towels side by side. With two smaller rails, check whether each can take a bath sheet without folding it into a thick bundle. Check children’s reach and make sure a hanging towel does not block a drawer or door.

Ask your installer to price the full job, including pipework routes, valves, fixings and any wall or floor repairs. If the rails will heat the bathroom, compare the combined output at your system’s operating temperatures with the room’s heat loss.
Frequently asked question
Can I keep the existing pipework with one wide rail?
That depends on pipe centres, connection direction and the position of the existing pipes. Compare the technical drawing and ask your installer what can be reused.
