Good day,
a joinery workshop will build a custom bathroom cabinet for me. On top of it will be a custom-made washbasin made of mineral cast. The width is approximately 140 cm (55 inches), and the actual basin, which should be seamless and integrated in the middle, is about 60 cm (24 inches) wide. Does anyone have any recommendations for manufacturers who make this kind of product? Ideally, the surface appearance would match the large-format tile we are still going to choose. Are there manufacturers who produce both large-format tiles and such one-piece washbasins? Attached is the design of the bathroom cabinet where this countertop with basin will be installed.
Thank you!

Keep in mind that such a dresser offers very little knee clearance. You often stand quite close to the mirror, and these dresser cabinets tend to be bulky. If the front absolutely needs to be closed, I would plan it deeper, meaning a lower height and consider a countertop basin. This way, you have more freedom of movement for your arms.

This kind of work is usually done with Corian, not with mineral cast. Normally, a carpenter can handle that as well.
Best regards

If your cabinet is being custom-made anyway, it should be possible to adjust it to fit the washbasin. The easiest solution is to go for a double washbasin, as there are many more options available in 140cm (55 inches) width.
Thanks first of all for all the replies!
I have never heard of "Corian" before, so I need to look it up. Maybe we will go for a granite countertop with an undermount sink instead. It seems that a 140cm (55 inches) wide vanity isn’t available as a standard option, at least not with a single sink in the center.
The lady of my heart wants exactly this vanity, and she doesn’t want a double sink either. That’s how we ended up with this exact solution...
