Installation of a mixer with hand shower on a built-in sink

The installation of a mixer with hand shower on a built-in sink requires to proceed in several stages.
It is important first of all to define the cuts to be made in the work plan. It is also necessary to equip the sink with the drainage system, which is, in this case, coupled with the evacuation network of the washing machines present under the worktop, without forgetting the connection of the shower mixer.
It remains finally to connect all to the supply and evacuation lines

Necessary material

  • Pencil, marker
  • Metre
  • square
  • Bubble level
  • Cutter
  • Hammer
  • Screwdriver (straight and cruciform)
  • Drill
  • Wood wick of 10
  • Metal Claw Saw 34
  • Jigsaw
  • Flat keys of 18 and 21

Steps

  1. Prepare the work plan
  2. Set up the sink drain system
  3. Set up the mixer tap on the sink
  4. Connect the mixer to the water supply circuit
  5. Connect the sink to the water outlet

Prepare the work plan

Prepare the work plan

1. Temporarily position the worktop, and mark in pencil the two markers of the interior width of the box where will be installed the bowl of the sink. Make sure that the handling of heavy elements (worktop and appliances) is carried out by two people.

2. Place the worktop, turn it over and place it on trestles.
The rim of the bowl of the sink being limited to 1 cm, you must perform the cut with the jigsaw upside down, so that the cutting chips inherent to this tool, are located on the opposite side to the face view.
From the two markers drawn at the edge, use a square and draw with a marker the two lines that will center the cut, to then receive the bowl of the sink.

3. Based on the marks of this centering (difference divided by two, the dimensions between the two lines drawn and the outer edges of the sink). Then draw a second line parallel to the first one.

4. On the same principle, make a trace in the axis of the work plan, taking into account the distance between the bottom wall and the edge of the sink, the tap being placed on the plane or on the border of the sink. Excluding specific features, take into account the internal dimension between the two consolidation elements of the box, to avoid having to rework them.
Finally, put the sink upside down based on these dimensions, trace its perimeter.

5. On the basis of this second plot, take the marks 1 cm inside, then draw dotted (to avoid confusion), the cut line of the plan. The latter will bring 1 cm of recovery to the edge of the bowl of the sink.

6. Using a 10 mm drill bit, drill four holes inside the four corners of the dotted outline. They will introduce the blade of the jigsaw used by cutting each line.
Manage the end of the hole carefully, so as not to burst the surface of the lower siding.

7. Position the jigsaw blade in the hole at the beginning of the dotted line, and then make the cut along that line.
Since the worktop is 40 mm thick, it is important to keep the saw flat for a vertical cut. Do not force the saw so as not to deform the cut and not break the blade.

8. When you arrive at the time of the last cut, position a third trestle under the part being cut to hold the cut area in place. You will thus avoid any tearing of wood, and also to receive the fall of wood on the foot.

9. When another cut is needed, for example for a cooktop, follow the same procedures as previously described.

10. Once the cuts have been made, move the worktop carefully and place it on the kitchen cabinet pedestals, tight against the wall.

11. Check the level of the work plan. It is important that it is perfectly horizontal, to avoid that a liquid spilled on the worktop does not flow to the kitchen or stagnates along the wall.

12. The various low furniture boxes are equipped with adjustable feet. Simply screw them to lower the level of the furniture, and unscrew them to raise them.

Set up the sink drain system

Set up the sink drain system

1. It was decided that the shower faucet would be located on the sink margin (wider edge) rather than on the worktop. As a result, measure the middle of this margin and spot it with a marker.

2. To drill the mixer tap, use a 35mm diameter metal hole saw.
Pierce gently so as not to distort the metal. Use a lubricant to prevent the hole saw from heating.
Also remember to wear safety glasses.

3. Traditionally, washing machines and dishwashers were evacuated by a single nozzle. This nozzle was able to receive the two drain rods on the same siphon connected to the kitchen drain line, the latter also receiving the drain of the sink. It is now possible to bring the whole together in one system. That of the sink has indeed two additional inputs above the siphon, they allow to connect the tips of emptying devices.

4. This system was chosen. We show here the two orifices, whose upper lids must be cut. They are intended for draining appliances. The side holes are for overflow evacuations (right or left depending on the position of the system in relation to the overflow grid.) Do not forget to blow up the inside of the precut partitioning membrane. using a straight-tipped screwdriver and a light hammer.

9. You can then stretch the white hose of the overflow system on demand. Then connect one end to the retained side port. You will have previously recovered the inner lid of precut partitioning, which you have blown up as indicated in 4. Finally introduce the overflow receiver (fitted at the other end of the hose), facing the dedicated gate.

6. You must then fix the counterweight on the hose directly connected to the hand shower (the color and diameter are slightly different).
The counterweight is composed of two parts. They must be positioned face to face around the hose, then tighten them with the two screws.

3. You can now set up the sink, once you've equipped it with fastening systems to screw under the worktop.
It is thanks to their tightening that you will maintain and compress the seals.
Also note that most of these accessories are only provided for worktops up to 38 mm thick.

You can also press the elongate contact located on the handle of the hand shower, it allows to obtain a change of flow of exit of the water. By pressing this contact again, you return to the starting situation.
