I've been asked to add a shower to a half bath in a business. The toilet, sink, and shower will share the same wall, the "wet wall". The shower will be a one-piece shell, placed in one corner of the bathroom, which requires moving the sink closer to the toilet (and all the plumbing relocation that entails) and building a stud wall to enclose the shower stall and a 2x6 frame pedestal to set it on so as to allow plumbing above the slab floor (the drain is in the wall directly behind the shower location -- lucky me!). Then sheet rock the stud wall and trim the shower and new wall with FRP.
How long would you expect this to take? My guess is about 10 days, as I'm not a professional.
But as to charging (just labor -- they will supply a CC for supplies), I can't charge for all the time it would take me; that wouldn't be fair. How long would you expect this to take a pro?
If you'd like to just throw out an ball-park $ estimate and/or give an time estimate and what the going hourly rate is in your area, or any of the above, it would help me rough up a figure.
Thanks for your help,
