Remodeling and what not to do

Well hubs and I have decided that the bathroom needs to be remodeled. Not a full blown remodel, just paint, redecorate and replace the toilet. Bathroom is now a icky green (what can I say the paint was only $5 on sale), and sort of a cowboy theme. After all, I do live in Horsetown USA. We are going with a very pretty pale yellow, almost cream, and a bit darker creme for the ceiling and one wall. Will be putting up wainscoting in white, with a wide baseboard and decorative crown molding. This will be white also. This part should be easy. Famous last words!! Where it gets tricky is replacing the toilet. We only have 1 bathroom. Repeat, 1 bathroom. Whenever we do anything that involves the toilet it takes great planning. By planning, I mean that we get out a bucket for emergencies and hope that we do not have to use it. I know icky, but what you gonna do??? Nearest gas station is over a mile away. Last time hubs changed out the toilet, it did not go as planned and it took quite a bit longer than normal. Here is where the what not to do comes in. When using a bucket, do not put your full weight on it. It sort of sunctions you in. I had to be rescued. Luckily only by hubs and not the fire department. That would have been way too humiliating:)
