Get a notebook where you have all your information. Yes- it makes you vulnerable to catastrophic notebook loss, but whenever I use various pieces of paper half of them disappear.

Planning upfront will always save time and hassle later. ( duh- right?) But recently I did a job where some tile wainscoting intersected with the light switch at the worst possible place on the pattern. I had forgotten to account for this ahead of time.

I went to Rejuvenation- a local reproduction lighting company that also specializes in vintage bath stuff, furniture and high priced gorgeousness. I measured their sconces, their sinks and medicine cabinets to get a sense of what’s normal. I had a general idea of where I wanted to put things but it’s always helpful to see what things looked like installed rather than just pulling a number out of book.

I decided the sink would hang 33” off the floor. The sconces 52” from floor and 5.5” on center form the edge of the medicine cabinet (which is 47 from floor to its bottom edge)

The window itself would be 30” from sill to wall.
