Unfortunate, I know. When you want something done and are looking forward to the results, you want it done NOW! But, this is rarely the case. And it effects the overall production that could be made. Due to all the lines you have to deal with, the bathroom is rarely a job that can get done fast. Especially, when you are doing a full remodel. Thus, you have to make sure you give enough time. Not just the amount it's 'supposed' to take but extra time. It's like having a contingency fund, you need a contingency week. You don't have to go overboard and say a month, but in the case small things get upset, you should at least allow an extra week before inviting friends to see the 'new' room.
