For several years I've been measuring friends' showers and hotel showers, and -- in my opinion -- 5'x4' is the ideal shower size. This is large enough to feel spacious and luxurious, large enough to house a shower stool, large enough to go door-less, if that's something that interests you ... yet small enough that it "warms up" and small enough that you can reach grab bars on both sides at once. In saying that, I should note that I'm a very small person. If you top 6', your mileage may vary. Also, the amount of glass in your project will affect its feel (if not its actual function). I wonder if you could take it down to 5' wide and use the extra space for towel storage; something like this -- pretend it's next to a shower: Do you own that many towels? I don't. For your space, I recommend something like this: Let the front half of the shelves open to the room for storage of towels, etc. You could include baskets in these shelves, or even a tall, thin hamper in the lower half. Then let the back half of this shelf unit open into the shower. This'd give you plenty of space for toiletries, etc. IN the shower (too much storage, actually, but it would be out of the line of sight from the main room), and you could use the lower portion as a hidey-hole for a teak shower stool (teak is best for water-purposes). I recommend a moveable shower stool instead of a built-in bench. You can buy them at Bed, Bath & Beyond for maybe $150. You can place it exactly where you want it: Under the rain shower today, out of the shower completely tomorrow, to the side for a child (or a sick person) to sit upon while someone else washes his hair. And if you ever have a truly sick person in the house, you can remove the small shower stool and bring in a full-fledged hospital shower chair (ugly but functional). Furthermore, wood isn't cold on the rear end like tile or stone. Shower heads ... How many /what type are you considering, and is it realistic that you'd want to run them at the same time? Without knowing exactly what you want, I'll take a couple stabs in the dark: - I don't see any point to a plain shower head PLUS a hand-held. I do see the point to a hand-held on a sliding bar so you can slide it up/down, but I don't think it's a make-or-break. - Remember that you want your hand-held to be accessible to your seat; if you go with a teak bench, no problem -- the bench can go to the hand-held's location. If you go with a stationary bench, you might want a second hand-held over the bench (which you'd never use at the same time as the main shower head). - If you're doing a rain shower head, this is a whole different function /not really good for washing yourself. Typically this'd be placed dead-center (a good reason to have a moveable seat), and it wouldn't be used at the same time as the get-down-to-business-of-cleanliness shower head. And related thoughts ... - Where are your wet towels going to hang? Or, are you considering a heated towel unit? - A big shower can be cold. Are you considering a heated floor, or a heater for the main room? -Think through your on/off switches. You definitely want them to be able to reach in with one hand and turn on the water without walking into the shower all the way /exposing yourself to that first burst of cold water. And even though you say you want to run the shower heads all at once, you definitely want each one controlled by a separate control. Get the shower you want! Agreed, but in any number of house-related things as I've investigated "the best stuff", I've realized that the status quo isn't what I really want. The shower YOU really want will require some homework.

Remodeling Magazine publishes a Remodel Cost Vs. Value Report each year which includes cost data for a variety of different remodeling projects organized by regions across the U.S. For your region, their data indicate a $21K cost to remodel a 5' x 7' bath at a mid-range quality level. Your master bath is larger and presumably you'd want a higher quality level, too. Here's a link to the online report: https://www.remodeling.hw.net/cost-vs-value/bathroom-remodel?y=2019 If you want to forgo a shower door, our rule of thumb is that you'll need at least 5 ft from the shower head that is protected with tile or glass. I don't see how you're going to achieve that based on your current plan. In addition to its effect on your vanity, splashing creates a slip/fall hazard in the area between the shower and toilet. Regarding your question whether eliminating the tub will torpedo your home's resale value, the answer is that it depends. It depends on 1.) consumer preferences in your local market, and 2.) the demographics of the most likely purchasers of your home. Best wishes for a successful project!

Thank you everyone for your feedback. These are really helpful! I've edited OP under last picture to include the approximate dimensions of the closet (and WH) plus total room. Sharon - you got it in the redo, that looks exactly right. I think the furniture piece would have to be on the north wall though (oriented like the vanity). The wall from corner to closet door frame is ~ 29 inches and the vanity is 36 inches. So it would be better to orient the other way? The 3D rendition is very cool. Suzanne - You're right about the baseboard in the bedroom. But I loved the idea, it hadn't even occurred to me to think about it like that. The door into the bedroom is right where the other closet idea would open into, although it could work as bedroom door opens to left. The bedroom has 2 closets on each side of bed (~45X25 in), but it would be good to have some closet type space (or furniture option) in bathroom, at the very least for linens and bath supplies. And you're right about the water heater too (we've replaced it, so had to deal with access). Need to percolate on these! Decoenthusiaste - The family bathroom we redid last winter was all in dark aqua porcelain! At least the shower/bath was full size but what a dark space it was. Can't wait to transform this space either. In regards to having the shower on the left (same as water heater) and double vanity on right, it seems like that will make the vanity/s the focal point (??). How important is that? Do people think a double vanity (vs a large single) is a big deal (from a selling point of view)? We have a family bath (on the other side/east) of wall of this bath. It's the long narrow style, but does have a long double vanity. There's just the 2 of us here now, but the house does have the 4 bedrooms.

Agreed, the cost will depend on your location, the amount of work you have done (moving plumbing or electrical will be $$$ more), the quality of contractor/workpeople you select, and the level of materials you select. I'm in North Carolina and in the very rough planning stages of an 8x5 (40 sq ft) bathroom. I'm budgeting $25-30k. If I was going to go with big box store medium level finishes I'd budget $20k. The most important aspect is that you find the best, most qualified contractor/workpeople. Just look at Houzz discussion posts to see all of the horror stories that happen when buyers go for the cheap, inexperienced workpeople. Or "experience" in doing everything wrong. You DO NOT want someone building out your shower who doesn't follow proper waterproofing.
