Plan the whole shower.
A trim kit is not necessarily a complete shower valve. Start with the experience you want, then list the controls, concealed parts and outlets needed to deliver it.
Understand the valve and trimDescribe how you want to use it.
Start with a short brief: an overhead shower, a handset, a bath-filling option, or a combination. Note who will use the room and where they should be able to reach the controls. Decide which functions you would like to use together and which you would use separately.
Take that brief to your installer before choosing the final valve. The number of visible handles is not a substitute for the manufacturer’s operating diagram. Ask the installer to confirm what the selected system can actually control.
Separate the body from the trim.
In a concealed arrangement, the in-wall body and the visible trim are separate parts of the specification. Some product listings cover only the trim. Check the inclusions before assuming the price includes the parts behind the wall.
Record both product codes, including every suffix. Similar names and matching finishes do not establish compatibility. For a replacement, identify the existing concealed body before ordering new visible controls.
Installation depth and service access belong in the installer’s review. Use the exact installation drawing and the intended finished wall build-up; do not choose a depth from a generic illustration.
Two manufacturer-listed examples.
These show how Jaquar UK identifies trim and in-wall parts. They are component references, not complete shower packages or a promise that another code in the same range will fit.

UK manufacturer listings checked 10 October 2026. Reference codes are reproduced as listed, without adding or removing suffixes. Confirm the complete supplied codes and current specifications before ordering.
Give each component its own line.
For an overhead shower, list the head and its arm or mounting arrangement. For a handset, list the handset, hose, holder or rail, and wall outlet where required. Mark anything already included in a kit so it is not ordered twice.
Next to each item, record the quantity, finish, product code and drawing. Label required parts separately from optional additions. A complete-looking photograph is inspiration; the written inclusions establish what comes in the box.
Do not assume every outlet can operate simultaneously. Ask for confirmation of the selected valve’s operation and of the water system’s ability to supply your intended combination.
Resolve the installation questions before buying.
- Can the water system support the proposed shower? Ask for pressure and flow checks, not an assumption based on the boiler name.
- Do the exact body, trim and outlet codes form the intended system?
- Is there enough space for the body, connections and finished wall construction?
- How will the installation be maintained and serviced?
- Are the control positions comfortable and accessible for the people using the room?
- Which parts must arrive before walls are closed, and which can follow later?
Use our bathroom order checklist to record what is confirmed and what remains open. The water-system planning notes explain the difference between pressure and flow. This is buying guidance; final design and installation need the relevant professional checks.
No email needed. Record exact codes and open questions in the worksheet, then keep it with your saved product shortlist.
