We are in the planning phase of a bathroom/kitchen remodel on a 1957 contemporary ranch house with original galvanized plumbing in Georgia. The plumbing is currently functional but annoying as we cannot do two things requiring water at the same time i.e. take a shower and use a sink, etc. without big pressure drop -- we've been told this is due to the old pipes corroding on the inside which diminishes the pressure and that repiping is the only solution. The supply lines are all in the attic and walls with drains running in the slab foundation. Attic access is very limited due to the low pitched/sloping roofline. But access should be pretty straight forward with a few holes in the drywall.
Here is our plumbing wish list:
Repipe from where the supply enters the house in bathroom #2 where there are 2 sinks and a tub/shower combo. We plan to replace the 2 sinks and faucets in this bath along with the toilet -- which is located in the adjacent hall bath. Also want to replace the original pink sink in hall bath. In the master bath which sits approx. 10 ft. from bath #2 (across a central hallway) we want to demo back to the studs and convert the tub/shower combo into a larger shower and put in a freestanding tub which will basically sit in the large shower pan area. We will need to remove a non load-bearing wall to expand the shower size and move the shower valve to the new wall and add tub faucet/drain (concrete will have to be busted to tie into existing drain). We also want to move the toilet 3 feet into it's own "water closet". Will also move 2 sinks/faucets approximately 1ft from current location on the same wall. Install gas tankless water heater which is in an adjacent HVAC closet.
Tie into existing gas line in adjacent HVAC closet and run line to new gas stove approximately 8 ft. Run water line for ice maker from existing capped plumbing (4' distance). Relocate drain for new sink 4' from existing and run new supply pipes (this will require trenching the slab).
We had a general contractor and his plumbing subcontractor quote $15,000 for the above. This price does not include any sinks, faucets, drywall repair or concrete demo/repair or cost of the gas tankless hot water heater. This price does not include repiping to the existing laundry room and outside spigot on the far side of the house. This estimate seems to be only for running the new PEX plumbing lines and making the connections only. Our question is -- does this sound at all like a fair estimate? Based on our ****** research it seems extremely high. We know it's difficult to ballpark any job without seeing the floorplan, etc. but we'd like to know if our assessment is correct and what a more fair price would be?
Sorry for the long-winded post -- but appreciate any feedback!
