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.

" I wasn't sure if you meant to include an image, or you were just describing your changes? " You know, I did modify your drawing but I forgot to attach it. Even though you already have your workable plan, here it is anyway: Thermostatic versus pressure balanced? They both work fine. In general, TS does hold the water to a tighter range than PB, roughtly +/-1 degree for TS and 3 degrees for PB. With TS, you usually have a control for temp and another control for volume. So once you set the temp control to a temp you like, you can leave it there. When you get out of the shower turn the volume OFF. When you shower next, turn the volume ON and the temp should remain where is was the last time you showered. With PB, there's usually a single control knob. You rotate the knob to set the temp, and in the process you turn the volume on. So each time you shower, you have to set the knob or lever to roughly the same "o'clock" position to get your desired temp range. I think PB valves are fine, I'm not biased against them in the least bit. TS valves are fine too. Both valve types work fine functionally, but there are probably more stylish choices available with TS valves. If people want "pretty" they usually go the TS route. "So what I'm thinking is one of the ones with a diverter, that would control the fixed shower head and rain shower, and then just a single one for the handheld. Does that sound right?" That'll work. I recommend placing the supply valves near the entry to the shower. That way you can open the glass door, reach in, and turn on the shower without having to step into the cold spray. Yes, you can go with two separate supply valves; one that feeds two heads, the other that feeds one head. That allows you to have different temperatures to the "his" and "her" heads if that might be an issue. Or you can go with a single supply valve that will feed all three heads and combine that supply valve with a diverter like the Quatro to get the water to where you want it. With Hansgrohe, pay attention as you shop. They have series' labelled as "C", "S", "E", for example. Pick your trim, then get the valve(s) to match. Good luck!

Yeah, my bad on the tub measurement - I was up in the wees talking to customer fraud rep in India - someone put a huge charge on my card. So not a lotta sleep last night. In a 60 inch tub, a medium or short person can stretch their legs but not while submerged up to one's neck in hot water. Sixty six inches, you get to do this if you are a tall man. If you are a tall man, you don't get to have straight legs and sink low into the water until you go to 72 inches. And 42 wide is pretty thin for two bodies when you subtract for the actual width! 48 would be much more comfortable. Also, make sure your floor can handle the weight of all this! The shower, the 42 width seems ok but not generous for width (it's do-able, though, without being cramped much), but 60 length is a bit too short for two people not to have to be quite careful. I think 72 would be good. There's nothing like actually blocking out the space and trying it, keeping in mind that in a shower you need more space than when dry as sometimes you are "blind" when your eyes are shut from soap, etc. so you need more margin. In such a large shower I'd pay extra attention to how drafty and cold it could be if you are not able to concentrate the heated vapors well. A huge open shower can be cold due to drafts!

Thanks everyone for the suggestions! There are good points in all the options. I think it over and over, even though I like the previous option #1 a lot, I realized the TV wall is a concrete wall, so cannot move the door open that way. I try to be more realist, like you said budget-wise and if I sell this unit in the future, they are likely don't need a hug amount of closet space. So I think I will make the shower room bigger and make lots of movable wardrobe units. I'm not sure what would be the best way to fit the pink wardrobe unit in the image below, I don't want the room to feel smell or separated: Option A - I feel the bed is close to the pink wardrobe might make it feel close to the wall, but the good thing is the room doesn't feel separated. Option B - The bed doesn't feel very close to the wall but the room feels separated with the pink wardrobe and created hallway which I feel it waste the space. Any other potential options? I like @damiarain 's idea of making it a big single sink and some draws on the side - I want to have a one piece vanity top with sink (not undercount), seems hard to find people to make it. @Flo Mangan I was looking for those closet lift, they all seem to be manual (could be quite heavy) on the market, do you know if there is an automate one?
