Choose the Installation and Control Format
Start with the pipework and shower layout. An exposed mixer connects at the wall with the main body visible. A concealed arrangement places the valve assembly within the wall and leaves the operating trim accessible. The installation drawing should match the selected control and the outlets it serves.
Shower Mixer and Control Models in the Catalogue| Model | Listed arrangement | What to select for the order |
|---|
| ZT-DDSFSID-WJ | Exposed wall mixer with manual hot/cold adjustment | Mixer-only or an identified hand-shower and rail combination |

Keep Mixer-Only and Complete Packages Separate
The same mixer can appear in several purchasing configurations. One line may cover the mixer and installation accessories; another may include a handheld head, hose and fixed holder; a third may add a slide rail. Keep each configuration as its own order line so the sample, quotation and packing list describe the same set.
The ZT-DDSFSID-WJ and TZ-CKDDSL catalogue ranges include multiple hand-shower combinations. The listed hand-shower combinations use a 1.5 m hose, while the mixer-only or installation-accessory base option does not include that hose. Select the configuration before comparing package contents or requesting prices.
Match Wall Connections and Concealed Installation Details
Listed Inlet Centres for the Two Exposed Mixers| Model | Nominal inlet centres | Adjustment stated with the illustrated connectors |
|---|
| ZT-DDSFSID-WJ | 150 mm | 130–170 mm with the illustrated normal eccentric connectors |
|---|
| TZ-CKDDSL | 150 mm | 135–165 mm with the illustrated eccentric connectors |
|---|
These dimensions belong to the named models and connector arrangements. Keep the selected connector set with the installation drawing and check it against the site's actual wall outlets.
For concealed controls, include valve installation depth, service access, trim dimensions and the pipe connections in the technical review. Specify whether the purchasing line includes the in-wall body, visible trim or both. This avoids treating a trim selection as a complete installation package.
Describe Outlets and Functions Clearly
An outlet count describes the connected water paths. It does not by itself describe spray modes, simultaneous outlet use or temperature-control capability. List the outlets you need—such as an overhead head, handheld head or spout—and connect them to the selected control model.
For a thermostatic specification, select a model explicitly identified for that function and review the operating requirements for the intended installation. A temperature display, push button or multi-outlet appearance should be recorded separately from the temperature-control function.
OEM Shower Controls and Coordinated Finishes
Develop your shower control range with the installation format, selected finish, package contents and branded packaging defined together. For project supply, connect the approved control assembly with the overhead head, handset and accessories in the room schedule. For distribution, assign an order reference to each finish and package version so repeat purchases remain clear.
