I spoke to Tommy the other day, he said he had my email and that he would be in touch regarding the bathroom work.
Given my misunderstanding of Göran's bill of work, I want to be sure I have a good reckoning of costs for this work before going forward. Using all the info I gathered on our February trip, I made an estimate of my own and came up with about 50,000 kronor.
The main variable in my estimate (guesstimate?) is the cost of labor (both price and hours) and all the ancillary stuff like plumbing, grout, etc. But at least I have something to measure against when I get Tommy's quote. If it stays in this ballpark, we'll be fine for my budget.
