Hello, Since you are planning on keeping the vanity cabinets with dark granite countertops along with white subway tiles, I think an easy solution would be to bridge the gap between the countertop and the subway tile by using a white marble look floor tile with dark veins. Below are just a couple of tiles I found on Houzz. I think using light-colored floor tiles would keep the bathrooms from looking too small or dark compared to using darker floor tiles. Are you also planning on painting the walls? I think painting the walls in a gray color would be also a quick and inexpensive way of making sure the whole space looks good. The current paint color looks like it's on the yellow side and I think your tiles, granite countertop, and the brown vanities would definitely look better if the yellow walls went gray.

I agree with Cpartist"s layout and like moving the closet over as suggested by D M so that bedroom 3 has easier access to the bathroom. Do you have room to have the toilet face the tub and add a linen cabinet next to the toilet? How wide is the tub toilet area?

Thanks again for all the good feedback. Moving the water heater out of the bathroom will be a last resort if we just can't figure out a solution to keep it all in there, but I'm determined to try my best first. The paper cutouts help with trying out different arrangements. My preferred option would be New #1, even if it makes the plumbing more complex. The water heater could be enclosed and have some towel storage above it, too. Using an 18" deep vanity should leave plenty of space to walk through (maybe I wasn't very clear in my original post, the width is 6' to 6'6"( that wall isn't in right now), so it is flexible where exactly it will land. I tried to use some actual product dimensions. Let me know if I am missing anything. New Option 3 is just a more elaborate version of the previous idea. This is really the only one I can see that could have a plumbing wall and still keep everything in the bathroom. A sliding door in the shower should work better than a hinged one, it will be a tight squeeze, but should work, at least on paper..... Option 3 is the one mentioned by wdccruise, where the water heater gets ejected. Critique away if you have anything I should know :)

Dear Weedyacres: One bedroom is 13 x 25, the other is 12 x 18. The other bathroom which is not in the drawing serves two bedrooms and one of those bedrooms is really tiny. On the other side of it is the dining room, so no way to make that smaller. I guess the only possibility at this point would be to loose the tiniest bedroom and turn the current master bath into one with the spiral shower, but I don't like that idea at all because we mostly heat that part of the house with the fireplace and I wouldn't want to loose a bedroom in the main section. Plus I think that really might affect resale value. Probably best to leave as is. I am so thankful for everyone's input because I think it's helping me to see that the spiral shower is a no go. Actually, the house isn't the main feature for me. The main feature is the two acres and lots of woods and the sun room with wall to ceiling windows. And the room we will use for dancing which actually brings me to another problem. The house is on a slab and we want hardwood. Sounds like engineered is the only way to go. We keep this room about 50 degrees and we want something that won't hurt our feet like tile would do. Thanks again for your help. I really do appreciate it very much.
