It is the one behind the sink, so will have wet handwash etc dumped on it, whatever "rules" I attempt to create. And some growing herbs. The other window already has a wooden sill.
Our tiles will be white glass, so I'm a bit nervous about their durability as a windowsill. And there'll need to be various tile cutting shenanigans and as a first-time tiler I need convincing it is really worth it.
But above all, I want something easy to keep clean - wipe&go, no risk, no brain-time required.
Any invaluable MN advice?
