Bathroom Mortice Locks

A bathroom door lock needs to do one thing above all else: provide reliable privacy that can be overridden in an emergency. At the DIY Hardware Store, our bathroom mortice locks are designed precisely for this purpose - fitted into the door edge, operated by a thumbturn on the inside, and with an emergency release slot on the outside to allow entry if someone becomes incapacitated.

Unlike a sashlock (which uses a key), a bathroom lock operates purely by thumbturn, making it faster and simpler for everyday use while conforming to the standard expectation for bathroom privacy. The mortice format means it's fitted cleanly into the door edge with no surface-mounted hardware beyond the keyhole cover and the spindle rose, giving a neat, integrated appearance that works with any door furniture style.

Bathroom mortice locks are available in standard backset sizes to fit most interior door thicknesses, and are compatible with the full range of lever handles, knobs, and turn-and-release sets available as part of a coordinated door furniture specification. Whether you're replacing an old worn lock, fitting out a new bathroom, or carrying out a general door upgrade across a property, the DIY Hardware Store stocks the sizes and finishes you need.
