Hi - I am planning on replacing a very sad and bedraggled hollow core
bathroom door with a sliding door.

Lots of places sell retrofit kits for a sliding door, but few seem to
sell an entire kit, door included. Two problems seem to present
themselves:

Should I get a door that is wider than the opening, so that there is
some overlap with the wall when it is closed?

How does one lock a sliding door easily...

ince I need a new door anyway, it would be nice if somewhere like B&Q
sold an entire set with a nice, basic, flush plain door, but they
don't seem to :-(

Cheers,

Ben
