Labor includes:

Removal of the old tub

Disposal of debris

Minor repairs (e.g., drywall, flooring)

Plumbing configuration

Installation of the new tub

Sealing and caulking

3. Plumbing Modifications

Older homes or those switching tub types (e.g., from alcove to freestanding) may require re-routing of plumbing lines, installation of new drains, or reinforcement of flooring. These changes can cost $400 to $1,500 or more, especially if the home's existing infrastructure is outdated.

Additional Costs to Consider

Bathroom Wall Surround Replacement

In most bathtub replacement projects, especially where the tub is part of a shower, you'll likely need to update the wall surrounds.

Acrylic or PVC Panels: $300 – $900

Ceramic or Porcelain Tile: $800 – $2,500

Natural Stone: $2,000 – $5,000+

Flooring Repairs

If water damage is found beneath the old tub, expect to pay $200 to $1,000 for subfloor repair or replacement. This step is crucial for safety and to prevent future mold issues.

Permits and Inspections

In some municipalities, building permits are required when major plumbing or structural changes are involved. Permit costs range from $50 to $300, depending on location and scope.
