Planning a Bathroom Remodel? Know the Real Cost of Bathtub Installation in 2025
A bathtub can completely transform the look and feel of your bathroom—but understanding the true cost of installation in 2025 is crucial before you start tearing out tiles or shopping for tubs. Whether you're replacing an outdated unit or upgrading to a freestanding centerpiece, this guide will help you understand the full scope of expenses and make smart remodeling choices.
Types of Bathtubs and Their Price Ranges
Freestanding Tubs
Popular for their visual appeal and spa-like vibe, freestanding tubs typically range from $800 to $3,500, depending on the material and design. Installation adds another $700–$1,500 due to floor-mounted plumbing and potential floor reinforcement.
Built-in or Alcove Tubs
These are more traditional and cost-efficient, with tub prices from $300 to $1,200. Installation is generally easier and costs around $500–$1,000.
Drop-in and Undermount Tubs
Requiring custom framing and a deck, these tubs range between $600 and $2,500, with install costs of $800–$1,600, depending on materials and layout complexity.
Key Cost Factors in Bathtub Installation
1. Plumbing Adjustments
Relocating or modifying plumbing lines (especially for freestanding tubs) can cost $300 to $1,000, depending on access and piping requirements.
2. Bathroom Layout and Space
If walls or flooring need to be removed or rebuilt, expect additional labor costs. Tight spaces or second-floor bathrooms often increase complexity.
3. Removal and Disposal of Old Tub
Removing an existing bathtub costs $100–$300, plus potential disposal fees. Additional repairs (like water damage) may add to the total.
4. Floor Reinforcement
Some tubs—especially cast iron or large stone resin units—require reinforced flooring. Structural enhancements can add $200–$800.
5. Waterproofing and Tiling
For built-in and drop-in tubs, proper tiling and waterproofing around the tub is essential and may cost $500–$1,200 depending on material and square footage.
