We just bought a house in Southlake TX that has this strange design in the master bedroom. It seems that originally was build considering a fireplace between the master bedroom and the bathroom. The prior owners used the space in the photos attached as the place to put the Tv. We do not have tv in the rooms therefore I am considering putting a fireplace in this space. Is ventless a good option? In terms of money how's much is the range including installation? I will appreciate your advice.
