Thank you for replying. I am now looking for an 18” wide cabinet to do just that. Do you think 21” deep (front to back) is big enough for the cabinet? I saw a sink that was 15x17 or another that was 15x15. Both were at least 9” deep which should be fine.

Fitting a faucet is your primary challenge when mounting a sink sideways. A 24” kitchen cabinet rather than a 21” bath cabinet will be a safer bet. Measure carefully.

And given your severe width restraints in that closet, consider how you will stand at that sink, wedged between your stacked appliances and the wall. Your washer dryer stack likely extends 27” from the back wall with an additional 3” – 4” to allow for supply lines and the exhaust duct. Hard to say without seeing your closet, but I think you might want the sink to come out into the room as far as possible? Good luck.

Thanks! We have a Miele W/D plus the dryer is ventless so they are not as large, whcih is why we got them. Trying to maximaize space as mich as we can. How much space do I need for the faucet? I thought I would get a 1-hole one with a pull down feature.

Every faucet is diffrent and space is sink dependant. Manufacturers specs are best guidance.
