Going back to the home improvement stores, I finally worked out a solution that:
- is easy to construct and install
- is more attractive (when the hand shower isn't attached) than the old solution (refer to the figure in the next step)
- is more solid/robust that the old solution
- doesn't spray out water at the tub spout
- allows the hand shower to be very easily attached and removed
- allows for full, unobstructed water flow while the hand shower is detached from the tub spout
The parts are inexpensive and should be fairly easy to locate at home improvement stores (such as, say, Home Depot); I ended up buying my parts at one of Canada's RONA stores.
Step 1: The Old Solution
Step 2: Materials
Here are the parts I used:
- 15/16" male-threaded, male chrome plated brass dishwasher snap adapter (ULN 406 in the figures).
- Female chrome plated brass dishwasher snap adapter to match ULN 406 (ULN 407 in the figures).
- 1/2" garden hose (I found some white marine/RV hose that had chrome
plated fittings. Too bad I could only use one end. A clear/transparent length
of hose might be another good choice.)
- 1/2" female hose coupling (I was lucky to find one that had the same blue/white
colour scheme as the hose).
[- optional] 1/2" male hose couple. (This is only needed if your length of garden
hose doesn't already have one--such as if I ever needed to make a new
hand shower, or repair the current one.)
- A shower head attachment. (I chose an aluminum fan spray shown in
the last two figures. Lucky for me, RONA makes their own and their company
colours again matched the hose.)
- Some thread seal tape (sometimes called plumber's tape or, incorrectly, Teflon tape)
Step 3: Installation
1) Unscrew the aerator from the tub's spout.
2) Wrap some thread seal tape around the threads of the male snap adapter and screw it tightly into the spout.
3) Cut the garden hose to a suitable length, leaving the female fitting intact.
4) Attach the hose to the female snap adapter and tighten securely.
5) Attach the female hose coupling to the cut end of the hose.
6) Attach the shower head.
7) Pull back the white ring on the female snap adapter to attach or remove the hand shower from the tub's spout.
I hope you find this instructable useful.
