I am still at the planning stage though I have about 50% of my bricks cut before our Irish wet season started.
I intend covering my hearth with polished granite as an impervious layer on which my underfloor insulation will sit. As the granite comes in 1m square tiles I’ll place weep holes to permit drainage.
I would like some advice regarding insulation under the oven floor. From various pictures I see two options.
Option 2, If I use this method do I need to have something around the outer layer of floor bricks to keep the oven floor from moving. Would cementing the outer row of bricks to the granite keep it stable or would this inhibit floor expansion. Do I need to allow for floor expansion?
Any suggestions as always welcome.

- The insulation it trimmed to match the shape and size of the oven ie circular.
- The insulation and oven floor are rectangular and much wider than the finished dimensions of the oven.
