Wiesbaden Caral Rombo extension kit for concealed thermostatic mixer

The Wiesbaden Caral Rombo extension kit for the 2-way concealed thermostatic mixer is the solution when the concealed body has been set too deep into the wall. Discovered after tiling that the control knobs can no longer be fitted? This kit extends the spindles by over 3 centimetres, so there is no need to chip out tiles and re-tile.

Prevents chasing work: resolve a concealed body that has been set too deep without removing any tiles, saving you considerable time, mess and expense.

Over 3 cm extension: the spindles are extended by more than 3 centimetres, more than enough to correct the majority of installation errors.

Compatible with multiple thermostats: the kit fits the concealed thermostatic mixers with article numbers 29.3960, 29.3965 and 29.2500 from the Wiesbaden range.

Neat finish: once extended, the trim plate sits flush against the tiling again, as though the concealed body was set at the correct depth from the outset.

Simple installation: the extension kit is fitted without breaking into the existing installation, so the job is completed in no time.
