Only after gutting our bathroom did we realize we might need some design help, and we've been living with it like that for 6 months (don't ask!).

We've already made some design decisions: 5' Tea for Two tub; small radiator behind the door, new medicine cabinet, 3x6 white subway tile. But we have a few questions:

1) We wanted to keep the sink under the stained glass window. This is our only bathroom upstairs and three women are often in it at the same time. We normally have a small cabinet under the medicine cabinet so someone can be putting on makeup or drying hair while the other uses the sink, etc. We thought if we put the sink on the side wall, there wouldn't be room for a cabinet, too. Is this a big mistake?

2) I think we thought of switching the toilet and sink, but didn't really like the idea of the toilet under our beautiful window. Thoughts?

3) We thought to put a towel warmer in, but only see a place to the left of the door when you walk in. We have one that is 24" square, but is that weird to put it to the left of the door? The ideal place would be near the tub, but there is no room on that wall.

4) We could possibly close in the shower/tub area, but didn't want to feel so closed in and thought the room would look smaller. We are moving the tub closer to the window and thought to open the area at the other end with a ledge. We also thought to use a glass panel half-enclosure.

5) Moving the door is a possibility, but would entail possibly ruining the molding in the hallway and having to replaster, etc.

We love our hundred-year-old house, and want to keep a look that is faithful to the era but updated. We will use 3x6 white subway tile on the walls and were thinking of a charcoal gray floor that looks like basalt stone. We were also thinking of doing a white carrara tub surround, niche base and maybe window sill (ours is crooked).

Any advice would be so appreciated!
