FWIW, the dimensions of my remodeled master bath, as well as the components of it, are almost exactly the same as yours (perhaps a bit smaller, as the bathroom is about 8.5 x 10.5). This was existing construction, and we didn't want to change the footprint.

Our doorless shower (shown below, both before and after the glass was installed) is appoximately 4x4, with an additional bump (another foot) for the bench area. Unless someone were to go a little crazy with the handheld shower, there is minimal splashing outside of the shower itself. Our shower does have a curb.

Our vanity is 8 feet long. Having the storage cabinet in the middle breaks up the length visually, and it is by no means too long.

Sorry I don't have better photos. The relatively small space makes it tough to get a better view.

bump, I have been wondering the same thing.

callaloo,
thanks for posting the pictures. they help me in visualizing everything. and i love your taste. tell me, where is the toilet?

When facing the shower, the toilet is to the right; the shower half-wall helps create a bit of separation (you can see a tiny bit of the edge of the toilet in the top photo).
