So far I've installed my waste and vent pipes as well as the water supply pipes. I just finished my electrical piping and wiring this evening.
right now i have bare studs, unfinished floor and pipes sticking up where my tub, shower and toilet will go.
I'm not sure what to do next...
start putting up the greenboard around the perimeter of the room?
start tiling the floor and set the toilet/shower and tub on top?
set the toilet, shower and tub in place, then tile around it?
is there a general rule of thumb when it comes to getting tasks prioritized?
If all electrical and plumbing rough in's are completed, call for your rough in inspection. Once the rough in inspection is signed off on go ahead and set you tub...you can set your tub prior to rough in call too if you'd like. Then insulate walls if doing so.
Now you can put down the flooring material but if this is a basement and your tiling I have to assume your tiling over the concrete floor so just use rosin paper and cover the floor to keep the drywall dust and crap off of it so clean up before you set tile is minimal.
Install wall board, tape, mud, texture and paint.
Install your flooring.
Install your final plumbing connections, final electrical fixtures, install your base and door casing, then install the toilet.
If tiling the tub is a long term fixture so run tile upto but not touching tub-leave enough gap so expansion contraction does'nt blow out grout lines and/or crack tile then fill gap with flexible grout colored caulk.
You want the toilet and vanity to sit on top of tile, this way should you ever decide to change them the newer design/profile will mean nothing since it's sitting on top of the tile...otherwise if you tile around these fixtures and ever go to replace 99% of the time you'll have gaps and goofy open areas that are left open because there is no tile there.
