On the Kohler website, there are sample layouts- I don't have it open right now to link to it, but you can find some options there!

This website offers lots of info and may have links that will help you. Disclaimer...I have no connection to this business!
Good luck!

Is this the master bath? Do you want a tub and a separate shower? Do you want one or two sinks? A separate toilet room? The 12 x 15 size of your bathroom isn't really small and at many stage of my life I would have been ecstatic to have that amount of space but it depends on what you want to put in it.

If you want a separate tub and shower that will limit your closet space considerably. Think about an arrangement with an aisle down the middle and what you can place on each side that makes sense to have each function (closet, sinks, toilet, tub, etc.) borrow space from the aisle.

I'm not good enough with my computer skills to post a diagram but I will try to describe one possibility. Our new master bath will be 11' wide x 14' long with a 4' wide aisle separating a 5' side and a 2' side. As you enter the room we have an 2'deep x 4' wide linen/supply cabinet on the left of the aisle and a 5' deep x 4' wide toilet room on the other side. As you proceed into the room we have an open space next to the linen cabinet for towel bars, bathroom scale, wastebasket, etc. that is 4' wide. On the opposite of the aisle from the open space is a roll-in shower that is 4' wide x 5' deep (if you can follow this, the shower is the same depth as the toilet room and adjacent to it). As you proceed further into the room toward the very large window at the end opposite the door, a 6' double vanity is on the same wall as the linen closet and the open towel bar space and opposite that is a soaking tub on the same wall as the toilet compartment and the shower.

If you do not want a separate tub and shower you could probably have a good sized walk in closet in the place where we have our shower and a reach in closet where we have our linen closet. Hope this helps.

Thanks, everyone, for the input. flseadog, 12x15 would be an OK size EXCEPT it includes closets. I think it'll end up being about 12x9 with the closets. I would like to continue to have a separate tub and shower.

What I've ended up doing is drawing it out on graph paper and cutting out shapes for the different components, kind've like you'd do with furniture in a living room layout.

Thanks

Sorry, that last like was supposed to be "Thanks again!"

Here are 4 options I came up with doing some electronic scribbling. Maybe they'll get your juices going.

Oh, weedyacres, those are great!

It's interesting that some layouts have the closet moved to the back of the bathroom, so the window is in the closet. I think it would be neat to have a window in the closet, but then there's no window in the bathroom. What are everyone's thoughts on the window being in the closet vs. the bathroom?

You need to ensure that your design is to scale. Bathrooms are tedious to design because plumbing requirements mean that fixtures have to be placed with considerable pecision. Invest in a good design software. We use Chief Architect, but this is more power (and cost) than you need. There is a simpler version called Home Designer which is an excellent lightweight design tool. Trying to do the design on paper, however, is almost certain not to work unless you are experienced with bath design.

You need to keep the window in the bathroom. Most baths suffer from inadequate natural light - so keeping as much light as possible is important. I also do not see any provision for power venting. You will need at least 70 CFM of ventilation.
