Ikea seems to work well. Annoying for us are all the downpipes with a circumference of 20 cm. We have 3 of them. what is the sill height of your windows? We have a sill height of 87.5 cm in the utility room, as everywhere in the house. For a washing machine under the window, it's too tight for us, right? The architect did mark it like that in the floor plan, but washing machines are about 85 cm high. Do washing machines on the base slab actually have to be connected on exterior walls? It would be important for my planning to know. I find our utility room really hard to plan.
