Cost: taps and mixer valves
Cost depends on model and integration: compatible replacement, adaptations or work on a concealed body. Separate equipment, accessories, labour, call-out and finishes. A new trim does not necessarily include the concealed mechanism.

Compare complete references
Record reference, finish and included accessories. For showers distinguish mixer, handset, hose, rail and concealed body. Compare supply and installation separately.
Separate replacement and adaptation
Price removal, fittings, possible isolation valves, substrate repairs and finishes. Clarify what happens if an existing part cannot be reused. Specify call-out, diagnosis and any minimum charge.
Assess repair and care
Compare diagnosed repair and full replacement with part references and service terms. No universal replacement age or automatic water saving is established. Consumption also depends on flow, habits and the installation.

Will a cartridge repair it?
That depends on diagnosis and availability of compatible parts.
Can concealed fittings change without opening the wall?
Some parts are accessible through the trim; an incompatible or damaged body may require work. Check the reference.
