First, the majority of the contractors have said that they won't need to tear out the bathroom and bedroom walls (including the studs) but another has said they will have to.
Second, the tub drain is a "straight" drain (there is no catch) that leads to the basement. One of the contractors wants to replace it and the others have made no mention of it.
Third, since I am looking at a whirlpool tub, one contractor wants to upgrade to a 50-gallon water heater (I currently have a 40) but the others have said nothing.
Can anyone help me out.
