In terms of access, this end of the tub backs up against a partition that is marginally wider than the tub itself, the exterior wall is only another 13 inches or so beyond that, so I have to slide in, lying down on my right side. In this position I'm either lying down on top of my right arm and working with my left (right handed, so not very easy), or stick my left arm up in the air or stuff it behind my back so that I can get my right arm into the hole. Either way it not possible to get both hands working on the project because the pictured section of pipe is under the floor heading in the direction of my feet. All of this is being accessed through a panel about 1' x 2' on the back of the partition. I do have an appointment for the same plumber to come out again but earliest availability is Monday after I leave for work (wife will be around). I was just hoping I could deal with it earlier since it's our only shower in the house and my weekends usually consist of other DIY projects involving dust, dirt and sweat.
