Ren8, L360 is the 11" joist. The builder has not specified which 9" one we would use; I presume the heaviest. We do have laundry on the second floor, but I guess that's more of a constant vibration, not something which would cause a lot of bounce? The reason I'm considering this is to give us more room in our entry. If I have to do the height between floors with the 11" i-joist, then would have a 109" floor to floor distance. For this, I need 15 rises/14 treads on the stairs (14 rises would give me 7.79", too tall for the code's max of 7.75"). Using Ren8's formula, 15 rises and 14 treads should be R=7.26R T=10.3, leaving only 3'8" between the front door and the stairs. If I could have a 107" floor to floor, I could do 14 rises/13 treads, R=7.64 T=10, with a 14" shorter running, leaving 5' between the front door and stairs. I can push the stairs back without making upstairs bedrooms smaller (they are already at a minimum). While the 3'8 isn't the end of the world, the 5' entry sure would be nice, which is why I'm trying to get a handle on the difference between the i-joists. I really have no idea which is appropriate, and I don't know how I would decide unless I could find similar houses with each joist, obviously not really a possibility. Thanks for the thoughts. Here is a link that might be useful: Link with floor plans (stair rise/run shown is not ideal)

Thanks for your replies. I guess I will just stick with the same setup I have now. It will still be a much needed improvement over the 70's look bathroom. I am going to stick with the 48" vanity but may put one sink instead of the two, so that I can have more room on the countertop. Even with the current two sinks, everyone uses just the one. Go figure. I'm not sure about jets in the tub. I saw a couple that were nice but now everone is telling me that jets in a tub are on their way out. Is this true?? I also want to stay with a 48' trifold mirror because I really like the one I have now. It is very functional when doing hair etc. Can see all angles. Unfortunately, I have had trouble finding an affordable one. Do you know of any large trifold mirror that doesn't cost a few hundred dollars or more. Thanks

Lots of good ideas here. Thanks! Joann - thanks for the picture. That is what I was envisioning, but I like having an example. I never considered green as the main wall color, but I like the idea. I'll have to find a subtle green though. I don't want the color to be too loud. I love the image of the stripes provided by dawnp. That is very do-able for me. I will involve my son in the selection, after I've narrowed down the choices. He picked the bedding, but has told me that he wants rainbow walls (not gonna happen!). I think he'll like the stripes in the example from dawnp. Maybe I can find some nice tans and greens for the colors. Les - we originally had the furniture as you suggested, but when you entered the room the edge of the chest made it feel blocked. But I do like the idea of creating a space in the corner for activities. Once we paint I'll play with the furniture arrangement again. Maybe it would be better if I placed the chest against the wall to the left of the table, rather than on an angle. What do you think? I'm on the hunt for a small book shelf. I'll also look at removable decals that would be fun for the next few years, but can be removed as he gets older. I'll look at shagreen once I find my samples. Thanks bestyears. This is why I love this forum! I've been looking at his room for a year now without any direction. Now I have it! Thank you everyone. I'll keep checking back in case anyone else has further ideas or opinions.

Standards for dimensional lumber have changed over the years, always, of course, becoming smaller. When your house was built the larger dimensions you have were standard. Today another quarter inch has been shaved off all soft wood dimensional lumber.
