I think it looks fantastic. One concern though - it will be a mess. The vanity surface, floor, walls and window over the vanity will get sprayed with soapy water. At the very least I'd install fixed, frameless glass on the half-height walls with a frameless glass door in between. Also, make sure the window frame is vinyl - it too is going to get very wet.

Looks like smitrovich found you some great pictures. For the eye rollers- if your home has a shared/"family" bathroom, some privacy in the shower means someone can shower while someone who might feel uncomfortable with a prolonged eyeful of your naked soapy self (an older child or sibling, for example) can use the facilities as well. Duh. its a look, with pros and cons compared to using a curtain, or building/tiling a wall, or using glass blocks. Upkeep, cost, lighting, drainage, ventilation, how hard your water is, accessibility, size constraints, waterproofing, safety, ease of use, and aesthetics are all important to consider with any of these choices.

"They [low priced nursery/garden center landscape designers] are used primarily as a marketing tool to sell plants, often very common or less desirable plants, and what you receive design-wise may be very substandard." My sentiments exactly. One would likely get the typical "builder's plan" ... the kind of problem prone landscape that everyone can't wait to redo as soon as possible. The forum is good for giving ideas about general direction to take, or spot problem solving ... but it does not produce PLANS, which are essential for a quality landscape product. One has the option of drawing their own plans if they are DIY oriented and feel competent about it. (They can get advice from the forum on the mechanics of doing it. ) If not, as in every other project, they must hire a professional. But landscaping without plan at all will probably result in something less desirable than a 'builder's plan.' The approach one takes for a back yard depends largely on one's goals and objectives. Some people want total privacy, as in a private paradise ... they don't want to see any part of neighbor's houses. Other people want a more open solution and prefer not to block much view between neighbors' yards. Still others want to block sight lines between theirs and neighbors' outdoor living spaces while keeping a feel of openness at other places. One needs to decide on their goals in order for a plan to shape up that would meet them. In nearly every discussion of creating a privacy border of some type comes the advice to avoid a uniform hedge. I would take this with a grain of salt because often, especially when space is at a premium, it may be the uniform hedge that best fills the bill. Many people here are plant loving "gardeners" and can't conceive of a planting that is not crammed with as much variety as possible. A potential downside to that is more labor in upkeep, more space consumption, and a busier look. If that fills the bill, no problem. But there are advantages to uniformity in potential space conservation, a cleaner look and simpler maintenance. Landscaping is not 'one size fit all.' Develop your goals and set about to see how they can be realized.

You might invest in some graph paper to make it easier to draw your floor plan to scale and to read it as well. If the bathroom has one door from a hallway, add only one sink, preferably centered, with two separate his/her cabinets above and/or below, with the center base cabinet shared -- toilet tissue, etc. Are you familiar with jack&jill bathrooms between two bedrooms? If the bath is between two bedrooms and you can create a separate powder room -- toilet and sink -- for each with a separate room in between those two powder rooms rooms for a shared tub or, depending upon the age of the children, a shared shower, you might consider that.
