Kirkhall -- I googled that, and I think that's exactly the right direction -- the walls have that sort of 'feel'. The only thing that doesn't seem to 'fit' is that the apartment has several long runs of wall without any seams, and it seems like those panelized walls are not that large. However, this building has a lot of units, so maybe they were custom panels.

How far have you gotten on this? Last year I would have said stacked stone in a charcoal, but today I say a dark plaster finish or an acid washed steel. You can never go wrong with all white smooth plaster, either. Or a fantastically beautiful slab...

Palace speaks the truth. Different walls will also have different light fall on them. I've had clients swear we used different paints on adjacent walls that where lit with different windows! So trial and error....Sherwin Williams colors to go! Or use the different materials as a feature and go with different colors.

Hello, I'm hoping to get some advice on what material the back wall is in the first steam room? The only thing I can find is a dark finish/wax product and that just doesn't seem right to me given the heat it will have. Thank you!
