Rectangular Baking Stone 5 "Too wide for an Aga Range Cooker Oven" Mr Spence 11 June 2019 Made this purchase based on 5 star review dated 4 May 2019 which suggested the item fitted an Aga oven. This is not the case. When measured, the dimensions of the stone are exactly as advertised and will not fit inside an Aga. The problem isn't due to Lakeland but poor advice from a contributing customer. A note from the team We're sorry this wouldn't fit your Aga range oven.
