To expand upon rich's ironic and humorous comments:
Yes, Shakers were/are plain. Ornament, like applied crown molding, was seen as superfluous and could lead to the path of damnation. Most parts of daily life were closely prescribed for the faithful. Their communities once thrived by taking in abandoned or widowed adults, and orphaned children. They also were expert at garden seed production and genetics.
Their doors were never overlay, always inset. The panels were raised on one side - the inside - to fit into the plow.
One who asks for Shaker will get Shaker from my shop. I will assume they know what they are asking for. The location of the plumbing is up to them. I have done Shaker reproductions that required extensive research and a few new skills to pull off. Same with 18th Century work - with one stalwart customer that has no electricity or plumbing in the house, but he has both in the Summer kitchen.
By the way, it was a Shaker Sister that first conceived of the circular saw in the US. She watched as a sash saw went up and down, and noticed that 50% of the time it was not doing any work (return stroke). She thought about it for a while, with the idea of wasted time/energy driving her, and then had "chisels on a wheel" made up to try. It worked.
