Who's going to clean that FST so close to the walls? I'd want a bifold/pivoting door (Aqua-Fold.)

We’ve had a tub like that in another house wasn’t a major issue. So you think a door is necessary? Our goal was flat walk in to the shower no door.

Aqua-Fold has no bottom track; hangs from the wall. It folds in half and can also pivot into or out of the shower.

My shower is 5' x 8', no door. Not cold. Not drafty. And my wife hates cold and drafty. Our shower head is closer to the threshold than yours. We get no splash out. We might get a few droplets when shampooing/rinsing vigorously...anything can happen there...but even then, there is a small tiled "drying off area" just outside the shower threshold. And that drying area is waterproofed under the tile as well. But for all practical purposes, in the 20+ years I've been using this shower, no water escapes the membraned footprint of our shower.

I'd recommend using only one of the heads you linked to as a..."fun" shower head. But not as your full-time shower head. Rain head showers of that sort, especially mounted on the ceiling (where rain heads should be), are nice at times. I have a 12" rainhead on our ceiling, and I love it...when I use it. But I only use it when I want that effect.

For a quick, effective shower, or a body-only shower, which is what I take 95% of the time, I'd recommend a wall-mounted head, or a hand-held on a vertical bar. My main shower head is that, a hand-held on a vertical bar. And with a shower as large as yours, I recommend a hand-held with a long hose. My hose is 8', the hose is long enough so the handheld can be used to rinse down the walls and floors throughout the shower when needed.

Good luck with your build.

my shower is also large like ^

I would never do a ceiling fixture only unless you always wet your hair. do a shower head on an arm from the wall.

I have a pony wall towards the front which keeps in the overspray.

I get a few errant drops here and there, but they're easily wiped up w/the towel after exiting. Even the top of the pony wall barely gets wet.

A shower needs tiled walls or glass walls (or a combination of both) to keep the water inside the shower. If you don’t have a wall of some sort, the water will bounce right off your body and out of the waterproof shower area. Only using a ceiling shower head will mean you will always get your hair wet unless you always use a shower cap: you will try to dodge the spray, but it will get you. A good wall-mounted shower head is easiest to use and you can keep your hair dry without using a shower cap.
