Hi. I think I'm going to make my own shower pan by laying a cement base (amongst other things like linings etc).
The place of the shower is good inasmuch as it's in a corner point, where the beams on the end are supported by a wall nearby. So, basically, shower is to be on end of joists, which joists are, of course, supported on the ends.
Okay. Imagine two floor joists about 410mm (appx 16") between centres. Of course, topped with floor boards.
What I intend to do is lay on top of the floor boards a sub floor (say 3/4" plywood) of size 640mm x 975mm. Now, imagine the joists are running from a north to south (top to bottom) direction - the left side edge of the sub floor board will overhang the left hand joist (which will be under the floor boards) by 80mm. The right sub floor board edge will overhang the right hand joist by 100mm.
The question is, is there any need to do any additional joist work under the floorboards? Such as add any joist pieces perpendicular to the main north/south joists. Thanks.
