Hi all, I'm currently renovating my bathroom in a property built in 1898. Having removed the ceiling and old ceiling battens I'm looking to install the new required timbers for the ceiling. There is only one truss within the bathroom area and another quite a distance just outside of the bathroom area. My plan is to counter batten but I'm struggling to find info on what the max span for 2x2's destined to hold the weight of plasterboard and plaster would be. I know I will have to fit new ceiling joists but if anyone could advise me on the max distance between them, that would great. TIA!
