We’ve got a combo boiler in a room which is attached to the house but currently can only be accessed by an outside door. It’s a small room and I’ve decided to knock through the wall and turn it into a bathroom. I wanted to get one of those tiny baths and put a shower in too. The combi boiler would need to stay in that room as there is nowhere else for it to go. Is that feasible/dangerous? I literally have no clue!
