Very well! After a good deal of online research (but evidently not enough) I had bought a skirted toilet because it would be easy to clean. Unfortunately, the plumber, Mike, told me that he couldn't install it because it could not be bolted properly to the floor, which meant that somewhere along the line it could leak and cause water damage before we even realized it was leaking. This would have been disastrous: we live in a high-rise. But Mike turned a potential problem into a solution by suggesting he go back to Power Plumbing, pick up a nice toilet there, and coming back to install that. And it IS a nice toilet! We are very pleased with it. Mike was also willing and able to haul the old one away (I'll be returning the skirted one.) It's wonderful to deal with people who know what they're doing, like Mike -- and Paul, (who answered my original inquiry here on Angie's List, and Rae, who sent us the insurance and license documentation we needed for building management approval of the project. I intend to recommend Power Plumbing to anyone who asks if I can recommend a good plumber.
