This is one of my favorite bathroom layouts.

You want more natural light in the shower/tub area? Maybe you can add a window.

I don't understand why there would be a wall when you first walk in. The head of the tub would be at the opposite end, on the closet wall. Just remember that your tub is wider than your vanity, so it will lessen the leg room while sitting on the throne.

benje: sUnfortunately that is not an option anymore. The new sidings already went up. :(

HM - What you have is a very good layout. If your only concern is light, do you feel that the ceiling light is adequate? Maybe you could add more recessed light.

Also, just because the siding is up, doesn't mean you can't add a window. It wouldn't necessarily be simple, but it can be done.

koote: There would need to be a wall on the opposite end of the shower head, because if not the water would splash out from the shower. I guess I can add one of those wrap around shower rod and curtain, but I don't think that is a very elegant look.

Another option is to make the upper 3 feet of the "stall wall" glass.

Chi- I have thought about doing that. But how do I put a curtain rod up on the glass? I need to use curtains and not glass doors because I will be bathing my toddlers there. If there is some way to put glass and curtain rod, it might be the best option. Thanks

Benje- I think lighting will be fine. I will have a ceiling fixture in middle of the room plus recessed light over the tub. There will also be sconces on the vanity. I will have one giant wall to wall mirror over the vanity, so it should reflect natural light. My concern is not the lighting, but rather I feel that wall seems awkward in the small space. But maybe it’s not? It just feels chopped up to me.

It's a great layout. The wall provides a nice extra bit of privacy for a person on the toilet. You might be overthinking this.
