If you're looking for a project...
+6 small pipe clamps (one on each end of the three APSH tube segments)
This setup has lasted through 5 different apartments. Wife mentioned she wished we had a double shower, and hated that we couldn't set one up in our apartment cuz we can't drill holes or w/e without owing a ton of money when we move out. Challenge accepted: made a double shower setup using only suction mounts.
One of these days I want to take this idea back to the drawing board and maybe use tension rods instead of suction cups, cuz they DO fail occasionally, which always sounds like a fucking plane crashed into our bathroom, but other than that we've both been super happy with it - even solo, having that hot water hit from both sides is peak comfort.
Also when selecting your shower heads and suction wall mounts, put some thought into how easily it will be to redirect the stream: ours aren't very mobile, and the weight of setup/tubing keeps them kinda fixed at a specific trajectory.
...iirc it was about $100 when all was said and done, but easily the largest chunk of that was getting two matching shower heads - you could probably go a lot cheaper if you find cheaper heads. ...or maybe not cuz everything is like 8x more expensive than it was 5 years ago...
Okay but how do you deal with your water pressure getting cut in half? Install a water heater pump?
The pressure from the wall is better than you might expect: nearly all shower heads have a pressure regulator inside of it - I'm assuming this is a legal requirement that manufacturers know users hate, cuz they tend to be easy to get at and bright red or blue. So, you'll want to pop the pressure regulator out of both heads.
Full wall spout pressure divided by two unregulated heads yields plenty on each side.
The issue you might run into is that your hot water will run out way faster than previously... then again, I live in an apartment, so I'm assuming our water heater is the cheapest shittiest one on the market, so you might have better luck on that front.
I'm just curious if you know the answer: does the regulator attenuate the pressure downwards even if the overall pressure is below the target? Say the pressure at the spigot is 100 psi, but legally must be at 40psi, so the regulator attenuates it down to 40. If you divide it into the two shower heads, will the regulators simply attenuate it down to 40 psi, or cut it down to something like 20 psi?
Anecdotally, one head w/ regulator at the start of the project vs 2 heads w/ regulators near the end of the project made a noticeable dip in pressure from each side. I thought the whole project was a bust - like, it was struggling to even rinse the soap off; but looked up ways to increase the pressure and found out about the regulators in the heads. Popped em out, and problem completely resolved.
You can still regulate the pressure manually too, using the valves on the t-connector. Ours are usually only open around 75% because they were murdering out hot water tank at full blast, and we'd run out of hot water with nearly every shower.
The regulator and water pressure both impact flow rate. Though as they said, remove the regulator and it's unlikely to be an issue.
