Rain Shower Head with Handheld: Building a Dual Shower Combo

How the parts fit together

The shower arm carries the water. ZHFS7719 screws onto the arm, and the fixed head screws onto the holder's male threaded outlet, so the holder sits in the middle of the run. Its large ribbed collar swivels through 360 degrees and its U-shaped cradle holds a hand shower, which is fed by a hose taken from the same connection point. The result is a two-head set with no wall drilling beyond the existing arm.

Because everything is from one catalog, the finishes match: the fixed heads, the ZHFS7719 holder and the interlocked chrome hoses are all polished chrome, and the handheld can be chrome, white, matte black or transparent depending on the range.

The diverter question, answered plainly

Retail listings for combo sets usually promise three states: overhead only, handheld only, and both together. That behaviour comes from a three-way diverter valve, which is a distinct part with its own lever or knob, not something a plain cradle can do. The ZHFS7719 in the ZHONGHE catalog is described as a shower-arm holder with a swivel collar, an angled body and a cradle, so the diverter function has to be confirmed as a specification rather than assumed from the photograph.

There is a simpler route that many programs use: a handheld with a stop button on the handle, such as ZH2256C or ZH2257. The set then behaves as one head at a time, with the handheld shut off at the handle rather than diverted at the arm. Say which behaviour the listing will claim before the sample is made, because the wrong claim on the box is the expensive kind of mistake.

Specifying a combo set for retail

State the fixed head model and finish, the handheld model, the hose type and the retail length your market expects, whether a diverter is required, the arm thread for the destination market (G1/2 by default, 1/2 inch NPT in North America), the flow target at a stated pressure, and the packaging format, since a combo set is a bigger carton than a single head and the carton drives freight cost.

Magnetic docking, where the handheld snaps to a magnet in the cradle, is not in the catalog. It would be an ODM development affecting both the holder and the handle, following the guide timings of about 15 days of structure design and 60 days of mold making.
