You will need more that one shower head. At a minimum you need an overhead water dump head and to the side a shower slide. Both should have independent controls so you can use one or the other or both simultaneously.
Water controls should be place high enough to avoid being hit by your hip and away from where you naturally stand in a shower. This will eliminate accidental extreme changes in water temperature.
Multi jet showers, where you are sprayed from every direction from up to 9 nozzles, are increasing in popularity. If you are considering an option like this remember you will need sufficient water pressure to get effective flow. Also note the plumbing needs special attention, the pipe distance from the mixer to the outlets needs to be exactly the same.
If you are increasing the numbers of outlets in your existing shower make sure the fall to the drain is steep enough to allow for the additional water, and that the drain itself can handle the increased flow.
Shelving
A shelf is needed in a shower. Shampoos, conditioners, soaps, and flannels all need to be at hand-height and off the floor. This is more for convenience although there is safety to consider with keeping slippery soaps off the floor. Shelves should be recessed into the wall to avoid protruding into the shower space. You want to keep your shower area as big as possible and any sharp edged protrusions need to be avoided. Alcoves can be build into structural walls around the shower and if this cannot be done shelves need to be rounded and shallow.
Steps and Ledges
There should be a ledge or step in the shower where a bather can place their foot. This is great for general stability when washing your feet or shaving your legs. The ledge also acts as another place for putting bottles and soaps. It can be from 100mm to 300mm deep and won’t make the shower feel smaller as shower size matters most as shoulder level.
Doors and Entry
Where possible try to keep the entry into the shower at floor level. This cannot always be done but it is something you should try to achieve where possible.
It is not always necessary to a have a fully enclosed shower. On some occasions a half wall 1.5m high is sufficient to contain the water. A glass wall can always be added later if you find splashes manage to escape. In particularly large showers even a shower door is not necessary as the splash zone does not extend beyond the slope to the drain.
The key to great shower design is making the shower area as large as possible. This will enable you to add more landing space off the floor and even do away with walls and doors to open up the entire bathroom space.
