Sounds interesting, how expensive is something like that? Your solution and approx. per m²
Makes me curious, is there already a picture of it in the forum?
I can't tell you the final price, but in the end for a 150x100 large shower it was 100 euros more expensive than laid Villeroy & Boch tiles. In the children's bathroom we used a Hoesch shower board, which looked similar and was cheaper (from "Solique," sanitary acrylic + dolomite). There are no pictures yet, just google Corian shower tray. Our house builder had some Corian/Kerrock in the showroom, it felt good and is probably warmer than tiles (we were not allowed to install underfloor heating under the shower tray).
