Tiled access panel - GIF

[Jon]

To make the panel tiles flush with the wall tiles, they have to make up for the depth of the mortar too. The fragility of the overhanging 1/2 tiles is questionable, but if this is just an access panel that gets opened maybe once a year, it's reasonable.

Real-world use could be an access panel for the inside of a firewood pass-through, via wall tiles on a hearth. Needs to be a bit beefier for daily use though.
