If you post the current layouts with detailed measurements and any must-haves, nice-to-haves, etc, you can get a lot of great advice here from professionals and other folks with talent in design. You may have difficulty finding someone who will do a plan for you who is not also involved in doing the work. Or you may be able to find a designer who'll do a plan for a set fee. Just remember when you start remodeling anything, there are always 1000 decisions and problems that pop up along the way. Are you prepared to deal with that as a DIYer?

Unfortunately it is a bit of a chicken and egg situation because you can't really get an estimate unless you provide the GC with the specifications because otherwise the estimates are meaningless and can't even be used to compare one against the other since god is in the details. What is your budget - you must have some amount that you have in your mind that is what you can afford to spend at the moment. Pulling a figure out of my proverbial arse, I would say that a moderate - not upscale bathroom - in a moderate but not high cost of living area would cost at least $15,000 if not more. Prefab showers or prefab/tub showers are quite a bit less expensive than the kind of tiled shower that most people covet because the materials for a tiled shower are more expensive and you need more highly skilled labor or you can wind up with a disaster. I suspect that my tiled moderately size shower cost at least $10,000 and perhaps more when everything was factored in - tiles, labor, framing, waterproofing, plumbing - including all of the fixtures and grab bars and the frameless shower door. It all starts adding up - and that is just the shower :-).

Without getting into re-modeling the basement, there's only one spot I can envision a small bathroom being easily put in, which is a walk-in closet. It's not super-small -- I had a folding table and computer set up there for a while I was working from home, and I've since converted it back to a storage room. I'd say there's enough room for a toilet and small vanity but no shower. I put a toilet in the basement in my other house, and it was a good move, especially since that house only had one bathroom, and it wasn't a large expense. The problem with this house is we're on a septic so I need a sewage pump, and from what the plumber said, it's at least $5K for just the toilet and associated plumbing, and in my mind that's a lot of money just for convenience for those times we're down there. But then again, you can't put a price on convenience.

I think you're showing the old and the new on the same drawing? As others have said, this is confusing. But the new master suite is a simple layout with a closet-bath-bedroom? Okay, if I'm reading this correctly, here are my specific thoughts: - Simple layouts are always best. Thumbs-up. - The hallway to the bedroom will make things private. But the hallway is something like 10' long and dull ... on the positive side, you'll be walking towards a door with natural light /makes for a good focal point. I'd like to see low-wattage motion-sensored lights in this hallway to make it pleasant at night ... if you place two lights midway in this hallway, the light won't spill onto the bed and disturb a sleeper. How wide is this hallway? I hope no less than 42" ... personally, I'd steal a foot from the ample bath and closet and add a set of built-in bookshelves into this hallway. I'd love to see it maybe 48" high with space above for artwork or display items. A 42" hallway with a half-high bookshelf on the left wall would feel luxuriously wide. This would give you a ton of storage and would create a more pleasant walk than an empty hallway. Imagine 10' of this: - I would definitely flip-flop the closet and the bathroom. Why? Because "as shown", you have the toilet sharing a wall with the bedroom, which can be noisy. In contrast, the closet is a quiet space. It also means when you want to use your own bathroom during the day, you're a step closer. - After making this flip-flop, keep the water items on the wall shared with the closet. This will mean more quiet for the secondary bedroom on the other side ... and if (when) you someday need service of some sort to the bathroom, a worker would be able to break through your closet wall, which means preserving your expensive tile. You could even ask for access doors to be left in the closet, which would allow you to reach the water works simply by moving the clothing out. - I'd definitely want a window in the bathroom, even if it's a small one up high over the tub. - Is that an open shower next to the tub? Eh, okay but not great. Personally, given that you have a very large closet right next door, I think I'd keep the tub at the end of the bathroom and create a shower that kinda "dips into" /steals space from the closet. I'd be willing to steal a bit from the large bedroom to make this happen. - In designing the bathroom, don't forget to plan where your towels will hang. - I don't know where you stand on closets-opening-from-bathrooms, but I think I might be tempted to close off the closet-door-from-the-hallway and open the closet from the middle of the bathroom ... meaning you'd enter the middle of the closet instead of the end. Maybe. - I note that you don't have a linen closet IN the bathroom, and that's something I really like. If you open the clothing closet into the bathroom, you'd be able to use that space for bathroom storage too. - I like the door in the master bedroom (fire safety), but I'd like to see a few more windows. The best rooms have windows on two sides to allow natural light from two different directions. - This is a fairly large bedroom, and you're showing only a bed in it. What do you plan to do with the rest of this space? My old bedroom was roughly this size (13' wide) and a king bed with two nice-sized night stands fit nicely on the short wall, but I was always a little irritated by the wasted space at the foot of the bed. - Where is your laundry? Ideally it'd be near the master bedroom as a step-saver. Your closet is large ... could you have a small stack-up unit in the closet?
