Quick Breakdown of Conversion Costs
The total average cost to convert tub to walk in shower depends heavily on whether you choose a basic prefabricated acrylic kit or opt for a fully custom-tiled enclosure.
To help you establish a realistic baseline, here is a quick overview of typical budget tiers:
| Conversion Style | Typical Price Range | Ideal For |
| Basic Prefab Insert | $1,500 – $4,500 | Rental properties, quick updates, small guest baths |
| Mid-Range Custom Tile | $5,000 – $10,000 | Primary bathrooms, durable porcelain tile, glass doors |
| High-End Luxury / Curbless | $10,000 – $18,000+ | Zero-entry designs, frameless glass, natural stone |
Key Factors That Shape Your Project Budget
When calculating the average cost to convert tub to walk in shower, several major project components dictate the final bill.
1. Demolition and Removal ($400 – $1,200)
Tearing out an old tub requires time and heavy lifting. Removing a lightweight acrylic tub is relatively inexpensive, but removing an older cast-iron tub requires sledgehammers, extra labor, and specific disposal fees.
2. Wall Surrounds and Pan Materials ($1,000 – $5,000)
The materials you select for your shower walls form the largest chunk of your budget. High-grade porcelain or ceramic tile offers custom aesthetic appeal, but requires waterproof backing and significant tiling labor.
3. Glass Doors and Enclosures ($400 – $2,200)
Sliding framed doors are economic choices, whereas thick, frameless glass doors elevate modern style but carry much higher material and installation price tags.
Plumbing & Structural Considerations
One major detail that influences the average cost to convert tub to walk in shower is hidden behind your walls: drain size.
Standard bathtubs usually drain through a 1.5-inch pipe. However, residential building codes often require a 2-inch drain pipe for walk-in showers to handle high water volume and prevent overflow. Expanding your subfloor plumbing to fit a 2-inch line typically adds $800 to $2,000 in licensed plumber labor.
Pro Tip: Before tearing down drywall, review local plumbing requirements via the International Association of Plumbing and Mechanical Officials (IAPMO)to confirm code compliance for shower conversions.
Choosing the Right Materials: Prefab vs. Custom Tile
Selecting the right materials balances durability, upkeep, and budget constraints.
Prefabricated Acrylic or Fiberglass Kits
- Cost: $800 – $2,500 (materials only)
- Pros: Fast 1-to-2 day installation, easy to clean, highly waterproof.
- Cons: Standard sizes, synthetic appearance, lower resale appeal.
Custom Tiled Showers
- Cost: $2,500 – $7,000+ (materials and labor)
- Pros: Fully customizable, luxurious aesthetic, strong ROI on home value.
- Cons: Takes several days to install, requires waterproofing membranes like Schluter systems, grout lines require periodic sealing.
DIY vs. Hiring a Licensed Contractor
Is tackling this project yourself worth the labor savings?
- When to DIY: If you purchase a multi-piece prefab shower kit, possess strong basic plumbing skills, and do not need to move supply lines or expand drain sizes, you can complete a basic conversion for $1,200 to $3,000.
- When to Hire a Pro: If you want a custom tile layout, curbless entry, or need subfloor plumbing adjustments, hiring a licensed contractor guarantees correct waterproofing and long-term structural integrity.
How to Save Money on Your Remodel
If you want to keep your overall average cost to convert tub to walk in shower on the lower end of the spectrum, apply these proven budgeting tips:
- Keep Plumbing in Place: Do not move the location of your showerhead or drain. Relocating pipes through floor joists dramatically increases plumbing bills.
- Use Prefabricated Shower Pans: Even if you tile the walls, pairing custom wall tile with a prefabricated acrylic shower base saves hundreds on custom mortar-bed labor.
- Choose Standard Tile Sizes: Large-format tiles (12″x24″) cost less to lay per square foot than complex mosaic patterns.
