A steam shower is so un-colonial I think you can just have fun with it and not be at all traditional. I think I'd look into some exotic granites or glass tiles or...I suppose Weedyacres is right. Gotta squeeze everything in before deciding what it looks like. But I do think you can get away with a completely unexpected style in that room.

Sorry I'm so late getting back to you. I think that oddly sized fixtures can be off-putting. Many home buyers are looking for an "ideal" and they can't see past that. If the tub is well made and the bath is located where it's most needed a shorter size tub might not be a problem. If the bath will be used by children then its size is less important, but children grow into teenagers. acm voiced a concern I had about the location of this bath to nearby bedrooms. My mistake in calling it water-resistant drywall. It looks like drywall but it's better referred to as tile backer board. It's most often 1/2 inch thick but I have seen a Hardie brand backer that was only 1/4" thick and came in 3 x 5 ft. sections. HERE is a link to more info on these. There are several types with differing properties. On toilet location, I don't think "obstruction refers to the nearest wall or fixture. I think it refers to something directly in front of the toilet. Looking at your floor plan an angled toilet would not have anything in front of it. There might be room between the toilet and the vanity for a waste basket.

We were quoted something over 3k to replace an existing cast iron tub (porcelain has worn through in spots) in the EXACT SAME SPACE as existing, with tub surround, not tile, but ONLY if we did the demo AND we did the finish work ourselves. Also I did not find this contractor to be very credible as one of the very-young pair that came out to do the estimate tried to convince me that the mildew on the caulk around the tub was actually *shudder* BLACK MOLD that was DEFINITELY ALL THROUGH the interior wall space and I would have to remediate that at additional cost. By them. Which they are neither competent nor licensed to do even if it were true. This kid also tried to convince me that the tile had been installed directly over wallboard (the home originally had plaster walls so it would have been over plaster not wallboard). He apparently failed to notice the one broken outside corner tile that has a chunk missing so you can clearly see the cement board behind it, LOL! In short, untrustworthy contractors wanted 25% of your entire budget just to put a tub and enclosure in. Forget any finish work whatsoever, and no demo at all. If you want to do it for that sort of money, you need to educate yourselves and do it yourself. Personally I'd live with it. I LOVE a great big tub! Certainly not useless to me! I'm sorry but 12k for what you want is not realistic even in GA. BTW, years ago, local JV schools used to offer classes to the public for all sorts of construction/finish work, mechanics, etc. I took lots of these classes. I don't know if they still do that, but were I you, I would check, and take as many as possible even if you decide to go with a contractor. Then you will know what questions to ask and have a better idea of how to evaluate the job before just signing a contract, even if you ultimately decide NOT to do any of the work yourself. JV - joint vocational schools. Sorry. That terminology is probably pretty opaque to people who don't already know what it means.

I apologize I wasn't clearer. I want to add a counter somewhere so I can have seating and get ready for medical reasons and then add some linen storage. I have some physical issues which require me at times to get off my feet when doing my hair and makeup. Not having drawers for the makeup vanity is fine by me as I can use a small acrylic storage unit to hold the few everyday items I use on the counter and the vanity will hold my hair products. Yes, adding a bigger vanity will allow for more storage but not a space to sit. The space to sit is the priority - it doesn't need to be big or fancy. We plan to be in this house for 20 years so resale is not really important in this design. The toilet IS in the bathroom and just has a door to separate it. We like this feature and will be retaining it - it's pretty standard here in my area. And to be real, it's common when you have 3 kids to have someone in the bathroom while someone is on the toilet. I also use a bathtub multiple days per week and don't like it in the middle of a room with space around it. As I mentioned in my original post, the shower is 3'6" x 6' so it's plenty big, it's just cut out of the picture here where the house extends out the front. My style is fairly transitional - I like timeless, clean, simple lines, not alot of pattern or anything busy. I'm pretty practical and want a pretty bathroom that's functional with the items I mentioned. Does that help?
