too many variables in your question, charge by the hour - the bid is never wrong that way
Hi, 'W. Depends a lot on what the tile is applied to. If it's on thinset on concrete backer board, a day's work, if you can pry up sections at a time. If it's thinsetted directly to a concrete slab, then it's one or two tiles at a time, with thinset and some grout still stuck to the slab, so back over again to shave that off, maybe three days of messy, dusty work to get a clean floor - and watch out for sharp edges. Using a rental Bosch demolition hammer will get it done, coming in at a low angle. And gloves, eye protection, hearing protection, dust-control plastic sheeting, and covering HVAC vents. One of the next projects here will be peeling the tile off the kitchen floor, previously installed by the former owner directly on the plywood sub-floor, estimated removal time around two hours. They will actually pop loose with no effort on my part, so I'll just help them along. (Too much H&G TV?)
