Today I made the sink for my cottage. It is made of soapstone. Real sinks are also made from soapstone. I believe the French word for this type of sink is "evier" My design is generic, the size based on the area I want to put the sink combined with the piece of stone I had. It was already this thickness and was long and wide enough to do the job. I left the natural edge on the front. I like the fact that the sink tapers at one end, it says "I am made for the purpose from salvage materials". That is what my fisherman families would have done often when they needed a home improvement project over the centuries.
These types of stone sinks are typically shallow in depth. I created a small drainboard area. The sink and drainboard areas were milled out using diamond coated burrs. I mounted the burrs in a drill press. They don't have to run at high speeds when shaping soapstone. Soapstone is soft and turns into talcum powder.
If you have always wanted a stone sink for your dollhouse you will find it simple enough to make from real soapstone, you don't need to fake it. A fence and a stop block or two helps keep the edges of the recessed areas nice and straight. You do need a depth stop on your drill press to control how deep you cut.
The sink will drain out through the rectangular recess at the bottom into a channel that goes through the wall. You will see that detail in a few weeks.
Now I need to make the riser blocks that hold up the sink. No taps for this sink, my rustic old cottage does not have running water.
