Thanks, but the floors aren't concrete - they are wood. This house was built in 1935. Isn't even a slab under it. Also, very tight space - maybe 8" on each side. Bathtub on one side, cabinet for sink on other. I'm going to call the local lumber yard tomorrow and see if they know someone locally. Otherwise I'm going to be paying a trip charge for someone to come out. I live just outside the 20 mile free no-charge zone (naturally). Oh well - you know what they say - **it happens.
