Budgeting a bathroom

The original bathroom for our farmhouse is 101" by 81". It was the only bathroom for 70-90 years, depending on when they built indoor plumbing and when exactly they added another bathroom upstairs (looks like 90's construction)
We changed the configuration, took out a bath and added a shower, moved the vanity and window. Tore out all the layers of linoleum both on the floor and wall. (sigh)
I was loathe to take out one of the few built-in storage units in the house, but did it since that is where the vanity now stands. Plus, found out that it was built over a heat outlet. So now we have heat in the room.
My original budget was $6000. Actuals are below:
Electrical contractor : $1300
Plumber: $1600
Flooring: $240
Toilet: $200
Tile: $45
Vanity: $60 (floor model sale - a scorchin' deal)
Fixtures :$110 + $60 (craiglist, restoration hardware and kohler)
Shower unit; $800 (craigslist, kohler)
Drywall, ceiling repair and window move : $450
Floor prep :$133
New window : $140

Craigslist saved my rump on this one. The fixtures and shower unit would have been totally out of my price range (who really pays $499 for a shower control ONLY) That total savings was $4700. The shower unit, kohler faucet, restoration hardware bath fixtures --boxes and boxes of them --(mirror, lights, towel rack, etc) were all new, unused in their original packaging. The only difficult thing was the finish. It is a brushed bronze, not really what I would have picked, but the price was right! It looks a little fancy in my bare bones house... but it is fantastic to have a bathroom downstairs again. And a toilet that can flush what a kid can produce without clogging. That right there is worth the money.
