The question about cost depends on several factors. Is the bathroom on the first or second floor? Whats below it?? Of course where you are makes a difference as well. We added a master bath last year. It was on the second floor, over a office below and there was no plumbing there at all. The plumber had to bring the entire stack up from the basement and then put in toilet, tub, shower and sink and put the vent up through the attic to the roof. The cost was about $5000- which I thought was reasonable. This was just the cost of labor- valves and fixtures were extra. We also had to pay a carpenter to box in the pipes in the room below and repaint of course!!! (One thing always leads to another) We are in the Boston area. You already have plumbing in the area, as well as an air stack through the roof. Remember too that depending on the size and circumstance of your space raising up the floor might make replumbing much less expensive than either putting it into the floor- or under the floor as we did. Good luck

weedyacres, thanks for all the advice! :) I don't know why everybody thinks I'm jumping into this tomorrow but this is something I don't plan on doing for another 3+ months, maybe not even for another year. Who knows. But by nature I'm very proactive and like to start planning so I can prepare. The kitchen is a different story because I am literally moving into a house with ZERO appliances - I don't want to live off take-out every night, and not even be able to take home leftovers! I appreciate everybody looking out for me in terms of budget and experience, I really do, but there's a lot of (personal) details I haven't added in my original posts. My mom updated her bathroom all by herself, and has done MANY other bathrooms for other people. This bathroom is much bigger than mine (the photo doesn't show it all). All new flooring, wall tile, mirror, faucet, shower fixtures, etc. She did this bathroom for $600, so I think my 2k tile budget is conservative. Oh and she is a house wife (no job), so she just spends all day doing this type of stuff. My budget outlined above was meant to include everything that is required (additional materials and tools if I don't have them already - I also haven't mentioned that I worked for SB&Decker for 3 years and have literally a closet FULL of Dewalt hand and power tools). I also have other friends who have just completely renovated their entire home by themselves (and were in my shoes less than a year ago). They had help from their plumber uncle but other than that they basically gutted and re-did their whole house themselves. We're all Engineers too, so we have a sense of structures. I might not understand house terms but I have a good sense of math and physics and have done a lot of research, calculations, and budgeting that I'm confident in. My GC is also a great guy, and has even offered to lend me his tools if I want to DIY things myself. I don't get into these details though in my original posts because I'm just looking for design guidance, not necessarily how-to's. You're right about my lack of knowledge with home DIY and construction, I'm a total newb! But I've been reading, researching, and watching a lot, so I'm learning every day. Houzz has just been another great outlet for me to learn, especially coming from people with firsthand experience! Fori is not pleased, I definitely plan to now. That's great advice. I'll look into what current code is and how my bathroom (now) meets it, and what would need to bring it up to code. My GC called out a few things during the initial walk-thru and he seems very familiar with the codes in the area, so he can help. I'll do all this before I start any renovating. When I say "new layout" I don't necessarily mean moving stuff around. Maybe I should re-phrase and ask how to design the bathroom. Mostly I just don't know what to do with the inset wall. Do I put cabinets all the way from the (current) sink to the door or do I leave empty space underneath and put a bench? What's practical? What would look nice? etc etc.

Most affordable is leave it alone. To do this remodel correctly, with the correctly waterproofed wet areas, is not going to be “budget”, even if you DIYed all by yourself. You will need to replace the window for sure. A window in a wet area is an invitation to rot. Unless it’s vinyl or fiberglass and integrated into the waterproofing system correctly. A limited space means limited options, as there are code required minimum spacing that must be followed. You need to figure out what you actually are willing to spend to get what you want. 20K? 40K? 70K? https://www.ceramictilefoundation.org/homeowners-guide-to-hiring-qualified-tile-installer http://starcraftcustombuilders.com/bath.design.rules.htm#.Wt9D4a9OnYX

Thanks for all the replies. J Design - the ceiling is 8 feet high. To the left of the photo (unpictured), there will be a new 60x30x18 tub. The back wall, pictured, is 80" including where the tub is. That leaves 50" and realistically 48" to play with if I space the edge of the sink at least 2 inches away from the tub. After looking more closely, I'll need a pedestal sink narrower than 22", the sink pictured is 19" and the tub now is 29" on the most outer part. ACM, I think unfortunately, having even a small vanity would seriously crowd the tub, or vice versa. We hope to put a partial glass enclosure but need to think about if we can hinge it at a place that still gives us room to exit the shower near the sink. Does this all make sense?
