I'm sorry but you don't have enough room for the tub and sink and toilet as you have them.

In version 1, you have 73" of wall space. Your tub is probably 32" wide. That leaves you with 41" of space for the toilet. A toilet needs a minimum of 54" space and in reality 5' is better. 41" is not enough room for the toilet and space to walk in front of the toilet, so #1 is out.

In version 2, you have 41" of space again because of the tub. Most vanities are 21" wide. That only leaves you 20" of space to walk through to your toilet. It's not enough space. Even with an 18" vanity you don't have enough space. You need 3' for comfortable walking space.

And again, with the toilet where you have it, if you take off the 54" minimum clearance, that only leaves you with 19" for your vanity.

Here is the only version that will work. It means a smaller vanity but it will be a heck of a lot more comfortable.

Cp I am not sure where you are getting your dimensions?

I was just asking where you were measuring from and the diagrams should help the op with planning .

Yes you did. I'm sorry. :)

The short wall is 85" not 73"?

Oops, you are correct. I saw 7 and thought 72"'. My bad. So let me recalculate.

Version 1: 85" of wall space minus a tub that is 32" wide = 53" of space for the toilet. If the OP puts in a 25" toilet, that will leave the OP with 28" of space which is tight but doable. If the OP puts in a standard 28" toilet, that leaves the OP with 25" of space.

Personally, I'd rather have more room depending on the age of the house inhabitants. If younger, then it's definitely doable, but if aging in place, it's way too narrow.

Version 2: will work better in terms of spacing. I'd go with 2.

Cpartist, I really appreciate your comments and input! I have two young kids and this would be their main, shared bathroom.

What are your thoughts in this configuration?

This is more to scale - a free standing 55" tub at the end, 6' vanity, 21" depth, and a shower 3' x 4'?

The clearance between the shower and vanity will probably be 27" give or take is that doable?

One of the issues with this room is that it is too big to be a smallish efficient bathroom and too small to be a big bathroom, maybe because of the window and door location

You have 7 x 10'6"

The post-war "standard" bathroom, which is what many second baths, baths in apartments or condos are, is 5x7. That means you have the floor space for two standard baths with a wall in between, if you could divide the room in half horizontally. So technically it's big.

I would not do a freestanding tub with open corners in a kid's bathroom. If you can move the toilet, that's great. I assumed from the first two options you could not since they are in the same place. 27" is technically allowable but in such a big bathroom it doesn't really make sense to have such a pinch point right inside the bathroom door. Also, someone will have to climb into that corner between the vanity and the tub and clean it on a regular basis.

It is pretty important to have the actual position of the door and window and their measurements in the drawing. It sounds as if the door can be moved, but the size of the window and its location and Sill Height are important in determining what can possibly go along that wall
