What did you install? Washbasin on a base cabinet or why was that a problem? I was actually planning to simply screw the base cabinet directly into the drywall pre-wall (double-layered). Do you see that as problematic?
We have a double washbasin and sometimes you also lean on it. With the original mounting, after a short time the toggle anchors came loose with double gypsum board :oops: hence the substructure. An OSB board behind it doesn't really cost much!
It is too late for an OSB board with us. But we also have a wall-mounted washbasin. So the wall only has to support the cabinet, no washbasin and no support.
Yes, I don’t really understand it either. But that’s how it is. The standard washbasin costs about €150 with the accessories. I think you can accept the loss. Especially when you compare that the washbasin we prefer costs up to 60% less elsewhere. Aren’t the drain and angle valves generally mostly standard?
It depends: there are production countries that don’t have our standards. Is that price for Ikea? With our standard sanitary ware, we could choose between two types of washbasins (countertop and wall-mounted). We then took the countertop and had a 160 cm board (EL) installed on site with the plumber for €50, and we got the supports ourselves. Later, we installed Godmorgon ourselves as a base cabinet. So I would always consider plan B and C. Pinterest only shows what you search for ;) although there is much, much more.
