In this case, the sensor module unit 3 comprises a channel 31 with two opposite sensors 301, 302, and the channel 31 matches the channel 21 of the water channel base unit 2 when the sensor module unit 3 is connected into the hole 20 of the water channel base unit 2.

(3) Furthermore, it may also be said that the water channel base unit 2 may be provided with a geometrical narrowing ensuring to keep a high enough water level for the sensors. This is not shown in the embodiment shown in the FIGURE.

(4) Moreover, electrical wire connections between the sensor module unit 3 and to the sensors units 30 (301, 302) are also provided, however not shown. Furthermore, such wires are also provided from the sensor module unit 3 and to a control unit or the like for the entire system having the capability of recirculating water or flowing water to waste (also not shown). Such wiring is arranged into the system during the production thereof.

(5) Moreover, in this case the water distribution module unit 4 is connectable to and detachable from a recirculation drain hole 22 of the channel 21 of the water channel base unit 2. Furthermore, a filter unit 5 is connectable to and detachable from the recirculation drain hole 22. Moreover, the filter unit 5 may have wings (not shown) which are intended to affect the water flow. Moreover there may also be an extra spraying hole (not shown) of the water channel base unit 2, which is provided in close connection to the filter unit/mesh 5. Such an extra spraying hole may have the purpose of enabling to free the filter unit 5 from debris, hair etc.

(6) Furthermore, as notable, the water distribution module unit 4 comprises two connections 41, 42. Both these connections are intended to be connected to a core unit of a recirculating shower. The connection 41 is a flushing tube, i.e. an outlet, enabling to flush water to spraying holes 23 arranged at different places inside the water channel base unit 2. This connection 41 is provided on the pressure side of the core and pump. Furthermore, the connection 42 is a recirculation tube, i.e. an inlet, intended for recirculation of water inside of a recirculating shower. This connection 42 is provided on a suction side of the core.

(7) Moreover, and as hinted above, the water channel base unit 2 is provided with spraying holes 23 (only one shown, but several may be provided) which are connected to a channel spraying connection 41 via a connection point 48 of the water distribution module unit 4, preferably via a channel network being a part of the water channel base unit 2.

(8) Furthermore, a channel 21 of the water channel base unit 2 has two ends 24, 25, one first end 24 arranged for water inflowing and one second end 25 comprising an overflow arrangement 26 which is arranged to send water to waste.

(9) Moreover, in this case there is an extra small drain hole 68 arranged at the second end 25. This may be arranged to ensure that water is not standing still in this end also after the drain hole 22.

(10) Moreover, the end 25 and overflow arrangement 26 may have different shapes, and not only the shape provided in the FIGURE. As an example, the end shape may be curved. Furthermore, there may also be arranged a countersink in the middle of the overflow arrangement 26 to ensure a better draining off in the overflow.

(11) In addition, the water distribution module unit 4 comprises means 43 for locking and unlocking of the water distribution module unit 4. It should be noted that the locking means 43 may be provided in many different ways, e.g. as a separate unit being fixated onto the water distribution module unit 4.
