I just renovated a 6X12 bathroom. Old cast iron tub removed. Removed and saved existing vanity and vanity top. Removed the toilet and replaced the existing rotten flooring and added on to the existing partially rotten floor joist. Removed the drywall and tile from around the old tub. After the new flooring was in I had to modify the existing plumbing to accommodate the new tub and shower surround. The hot and cold water lines had to be raised to fit the surround because the new tub is taller and the drains had to be installed and moved to fit the new tub. Drywall was finished and painted. New faucets,New tub,Tub Surround, and flooring materials were purchased by the home owner. Labor cost was 4,584.00
Having an onsite dumpster should be your responsibility if it is something you are going to demand. They aren't cheap. Make suggestions or request a dumpster be included in the bid, but I would never start demanding anything when requesting proposals. They may have their own suggestions. We own a dump trailer and we bring it during demolition to handle the large debris. We have the trailer to avoid having to rent a dumpster on the job. If asked we can share this information, but if you require a dumpster instead we would have to take the time and research getting a dumpster to your house and add in costs we aren't accustomed to adding. That takes time and effort we may just not want to expend to give you a quote. Good contractors are generally very busy.
As the home owner, I am providing about $8,000 in materials. This includes the cabinetry, fixtures, faucets, countertops, lighting, toilet, glass in-line shower door and tile. Received two quotes. One contractor wants $25,000 to demo the bathroom, convert the existing tub to a tiled walk-in shower, tile the floor, and install my materials. The other wants $27,000. Using the previously mentioned 60/40 labor to material rate, I would be paying more than double for labor...that's insane. Some contractor's need a reality check.
Yeah, I feel your pain. I'm in Alabama, one of the lowest income states in the country, and I got a quote from a "big box" hardware store here. $39,000 -- to remodel a 9 x 12 bathroom. I won't go into the details but I'll tell you that the estimate included $3600 for electrical work. Uhh, we are simply switching out 2 'regular' outlets and putting in $20-dollar GFI outlets. The wiring is fine (I know because I've been in the wall before). So don't go to the "big box" stores unless you want the highest possible estimate (oh, yeah ... I had to pay for the estimate as well).
