How to Replace the Shroud Kit on a Mira Agile Sense (UK)

UK guide to swapping the shroud kit in a Mira Agile Sense shower valve. TMV2 compliance, part numbers, tools.

Mira

The part

Replace the concealing plate and shroud on the Mira Agile Sense where limescale has locked the temperature handle.

Isolate

Undo the two handle grub screws (2.5 mm hex on most Mira models). Lift the shroud off — do not lever, it cracks.

Swap the shroud kit

Fit new O-rings between the wall plate and shroud to keep the IP54 rating.

Commission

Balance hot and cold to within 0.5 bar. Run the Mira Agile Sense at max flow for 3 minutes.

Verify max outlet temperature stays below 46 °C per BS EN 1111 by shutting off cold and reading the outlet.

Frequently asked questions

Chrome or brushed?
The Mira Agile Sense kit ships in polished chrome as standard. Brushed finishes carry a -BR suffix.
Wall plate offset?
10–35 mm adjustment on Mira concealed valves — use the shroud packer to hide any tile mismatch.
OEM or aftermarket for Mira?
For TMV2/TMV3 compliance always fit genuine Mira cartridges. Aftermarket voids the Agile Sense approval.
