It depends on the origin of the leak. If it's just the drain you might be able to tighten some fittings. In many of the older homes, (20 years or more) there is a pan seal used on tile showers that keeps water from leaking past the drain. The pan used back then was basically a hard tar paper/rubber combination that failed over time and ends up leaking. The tar paper was folded such that it fit tightly into the corners and up the wall approximately 4 to 6 inches. If the pan sealer has failed, the only real option is to replace the shower since you'll need to pull the tile to get to the pan. The pan used today is vinyl and won't break down like the old ones did.
Yes, the upstairs shower is leaking through the ceiling.
There is a main drain that runs from the basement through the roof where it is the vent for the system. If you look at the layout of the house, the upstairs bath is most likely over the downstairs one or the kitchen. If you look on the roof, you will see a 4 inch pipe coming through the roof that should be over the upstairs bath. The sink and shower drain into that and then to the basement and out of the house. Most likely the main stack is in the wall behind the toilet.
Installing a steam shower in the basement is not a good idea. The steam shower should be installed in the nbathroom of your home.
The Bobrick shower curtain cannot be installed in the ceiling. It is made be installed in the shower wall brackets.
To effectively remove and prevent mold in your shower ceiling, you can use a mixture of water and vinegar to clean the affected area. Scrub the mold with a brush and then rinse with water. To prevent mold from coming back, ensure proper ventilation in the bathroom, fix any leaks, and regularly clean the shower area.
There is a clog between the sink and the line to the street or septic tank. The sink is the easier path for the upstairs shower.
To properly install a shower rod from the ceiling, follow these steps: Measure and mark the placement of the rod on the ceiling. Use a stud finder to locate ceiling joists for secure installation. Drill pilot holes into the ceiling joists. Install ceiling brackets or hooks securely into the pilot holes. Attach the shower rod to the ceiling brackets or hooks. Adjust the rod to the desired height and ensure it is level. Test the stability of the installation before using the shower curtain.

To hang a shower curtain with support from the ceiling, you will need a ceiling support rod or track with corresponding hardware for installation. Measure the distance from the ceiling to the floor to determine the appropriate length for the rod. Install the rod securely into the ceiling joists or use appropriate anchors to ensure stability before hanging the shower curtain.
If the toilet and shower are in an upper floor then there is a PVC drain for both that will drain to either the sewer or septic. If there is a vertical piece to this, as there is in my basement, then you actually get some dribbling and running sounds from the water 'falling' down that vertical PVC. I get this same noise from the washing machine on the main floor draining down to the basement.
You can purchase a ceiling shower head, and just about any other part for a shower from Home Depot, Lowe's, Ace Hardware, and Sears. Sometimes Costco will also carry them.
If the tub has a shower as well, the pipe from the faucet to the shower head could be leaking. You might also check the tube that comes OUT and fills the tub. It could be leaking back at the valve when you turn on the water.
