Mission (From 400 miles away): Build a replacement, mirror image, bath vanity ... and build it around pre-existing doors (3) and drawers (4).
(the original (built-in) vanity was damaged, irreparably, by a leak and had to be removed).
Sketchup to the Rescue, once again:
My helper and I used a Bosch Digital Laser Distance Measurer to dimension the _precise_ details of both bathrooms "as built", from floor to ceiling and in between, using SketchUp to do a 3D model, during our initial visit to meet with the client and firm up a deal.
... in short, bringing both bathrooms, exactly as they exist, back to the shop, 400 miles away, where cabinets can be built, and everything necessary to buy/bid floors, vanity tops, sinks, back splashes, tub surrounds, plumbing and electrical fixtures, and collaborate and keep the client informed, via our various digitally connected devices, from the shop.
Ain't technology wonderful, eh?
