Hi I am trying I stress trying to install a new bath tub & faucets My mom says we have to screw the tub to the wall to make it flush this is a plastic tub & thats the reason we are replacing the old one because it was screwed to the wall & 5 yrs later cracked around the screws. Is there any way around this. Also when we took the old faucet off we had to do it in 100 pieces because the hoses in the wall dont turn I really dont wAnt to take the new one in 100 pieces & then try to put it back toghther. Please Help
