ᐅ Tiled shower floor – sooner or later problems caused by the silicone seal?

Hello everyone,

If I want to tile the floor of my shower area, won’t I sooner or later (likely after more than 10 years) encounter problems at the following spot:
the silicone joint between the outer floor tile and the first vertical wall tile next to it? This joint will surely be filled with silicone or acrylic, and sooner or later there will be a leak there. Then water will run—without me noticing much—under the tiles while showering.

Isn’t this a major drawback of tiled shower areas?

Thanks and best regards,

Are those tiles rated R11 (slip resistance class)? We're looking for R11 in light/cream/beige for the floor including the shower.
Slip-resistant R10 A Villeroy & Boch Unit Four Greige. On the wall Unit Four Wall Cream. We couldn’t stand a gray and white combination like almost everyone has nowadays anymore. That kind of look just isn’t cozy.

So you can’t have any pipes from the underfloor heating exposed, right?
Or did the tiler cover the exposed pipes with their mortar until then?

Yes, you can. It doesn’t make any difference for the tiler.

Or did the tiler cover the pipes that were sticking out with their compound?

Yes, that’s right. It was done the same way for us.

There is no underfloor heating in the shower itself. It is only installed in the bathroom floor.

Yes, I will probably do that. I see it as an advantage to also lay out the square meters to get "more" space. Every little bit helps.
And then have the tile installer lay that area themselves (instead of the screeder).
Good plan. How much distance should be left between the drainage channel and the underfloor heating pipes to prevent drying out or unpleasant odors? It always dries out anyway when the house (within the thermal envelope) is warm, right? I read something about the spacing because of negative smells. But hmm 🙄

No towel warmer? In our case, I will solve this by having the presence detector in the shower activate both the light and the towel warmer. This way, you always have a warm bath when you need it, and the underfloor heating takes care of everything else. At the same time, I would even switch on a heated mirror, but those tend to be quite expensive.
