Cast iron$12.50–$30
Copper$2.50–$15
PVC$0.75–$7.50
PP$1.25–$15

Cast-iron drainpipes, which are common in houses built before the 1970s, cost an average of $12.50 to $30 per linear foot.

Copper

Copper drainpipes cost between $2.50 and $15 per linear foot. Copper is an excellent choice for drainpipes because of its durability and longevity.

PVC

PP

Polypropylene pipes are also cost-effective and range between $1.25 and $15 per linear foot. While more affordable, these pipes are less durable than metal ones.

Materials

New drainpipes cost between $0.75 and $30 per linear foot. The total cost will depend on how much pipe you need to replace and what type of pipe you use. Materials like cast iron and copper are more expensive than PVC or PP pipes (more on this below).

Labor

Labor costs an average of $45 to $200 per hour. In most cases, you should leave drain replacement to an experienced plumber. The last thing you want to do is accidentally cause a leak to the floor below the bathtub, which can cost between $45 and $55 per square foot to repair.

If installing a new drain requires tearing out part of the wall, new drywall installation costs about $2,100. Other elements of your bathroom that might need repair after pipe replacement include cabinets and tile. Most importantly, if parts of your foundation are disturbed, prioritize fixing them. 

When pulling out drainpipes, you may find a leak and surrounding damage. Repairing water damage costs between $1,350 and $6,100, but your costs will depend on the extent of the damage.

That said, drain replacement and repair are best left to the professionals. If you install a replacement drain incorrectly, it could result in water damage repairs to your home.
