Receivers that do not need a prior seal

The principle of showers without a shower, or walk-in showers, is based on the use of a floor drain and a waterproofing under the tiles: this is ensured by a lead or synthetic casing.
Both require a certain technicality since it is then necessary to make a screed with slopes to channel the water to the siphon. This complexity has now disappeared with the appearance of receivers ready to tiled which can, as is the case on this site, do without a prior seal.

Tile construction panel: an all-in-one product

Several manufacturers offer these models of building panels to be tiled (Wedi, Schlüter-Systems, Nicoll, etc.).
Here, the preformed panel (Fundo de Wedi) is coated on both sides with a fiberglass reinforcement, embedded in a thin layer of special mortar, which guarantees the tightness of the product. In the periphery, the soil-wall sealing is ensured by specific strips of non-woven fibers, embedded in a two-component mortar.

Evacuation: a tailor-made solution

The set takes place directly on the ground subject to embedding the siphon (a siphoid bung is sold with the screed). If there is one rule in terms of evacuation, it's the one to do the shortest...
In practice, you must try to aim for the nearest fall column. Knowing that a slope of 2 to 3 cm / m is required for this pipe, its installation sometimes poses insoluble problems.
That's why this manufacturer has developed an extension (same type of material as the panel), which can be cut with a simple handsaw or cutter. No filling with mortar or concrete is necessary, then just put on the preformed panel of the receiver...

The shower is delimited by walls of tiles and plasterboard waterproof. The bleeding intended for the evacuation is partially filled up with a smoothing compound.

The screed extensions have notches to facilitate their assembly on edge and at right angles.
One of the extensions is pierced with a hole. Orient it on the evacuation side.

Before final assembly, the extensions can be re-cut (with a handsaw) to circumvent an obstacle (piping...) or adapt the dimensions of the assembly to the available surface.

The bung takes place in the center, where the 4 risers intertwine to prevent any decline in this area.
Recessed, the edge of the bung does not form any extra thickness.

Present elbows and blank tubes and mark their orientation with the felt.
Deglaze their contact surfaces with the medium abrasive.
Then coat them with glue.

Assemble the parts without changing their orientation to avoid disturbing the glue.
Check the seal by pouring about 1 l of water through the bung hole.

After drying the glue, attach the risers to the floor.
Use polymer glue or tile adhesive mortar.

Glue the top of the risers.
Before placing the preformed panel, screw the main halves of the bung into one another, on both sides of the panel.
Do not forget then the O-ring!

Check the horizontality of the clevis on the spirit level.
If needed, lightly press the uppermost end to remove excess glue.

Perform peripheral sealing with non-woven tape, embedded in a layer of two-component special adhesive (supplied).
Marouflage and eliminate oversizes.

Another band of the same type is needed in the corners, in vertical parts.
It alone will guarantee a perfect seal at the junction of the walls, through which infiltration is always possible.

3 Laying tiles and mosaic

Glue the front edge of the receiver in a fairly thin pass: not to lay the mosaic but the stainless steel profile forming the stair nosing.
Then check the horizontality of the riser.

Cut the stair nosing to the desired length and embed it in the mortar.
No special precautions should be observed here, but press the profile lightly along its entire length.

Align the first mosaic plate against the wall and the stainless steel profile.
Progress to the other end and re-cut the last plate to the cutter.

Then pass a trowel over the entire row to check its flatness. Repeat the operation to cover the entire surface leaving aside the bung.

Since it is not possible to put whole tiles up to the level of the bung, cut some of them in the most regular way possible: for example at the grinder and along a cleat or as here at l using a cutter.

Remove the excess glue with a tool (brush handle, sponge...) so that the mortar penetrates everywhere.

After 24 hours of drying, apply the joint mortar.
It also results from a mixture of powder and water, liquid enough to easily fill the gaps under the pressure of a rubber squeegee.

Supplies for laying a shower tray ready to tile

• Shower panel to be tiled ("Fundo" by Wedi)
• Enhancement (Fundo Primo Easy Set by Wedi)
• Seal kit (tape and two-component adhesive)
• Polymer adhesive (Wedi 610)
• PVC pipes and elbows Ø 40 mm (or 50), glue for rigid PVC, abrasive medium grain (80 or 100)
• Floor and mosaic tiles
• Tile adhesive mortar, joint mortar (Cégécol, Parex Lanko, Weber...)
• Step nosing (1/4 round aluminum profile)

Receiver ready to tile: another solution

The ready-to-tile shower panel is available in a slightly different version at Schlüter-Systems ("Kerdi Shower").
It comes in two panels: the first, extruded polystyrene, serves as a support for another panel, expanded polystyrene and shaped pyramid inverted. Between the two takes place a siphon. The top panel is to be covered with a polyethylene mat coated with non-woven felt (from the same manufacturer). Fixed with a special glue, this mat ensures the watertightness of the shower and the surrounding surfaces when it is on one level with the rest of the bathroom.
