If your large soaking tub has turned into a laundry basket or a step-over hazard, you’re not alone. Many Michigan homeowners are replacing unused bathtubs with walk-in showers that are safer, easier to maintain, and better suited for everyday life.
Converting that unused tub into a sleek, modern walk-in shower is one of the most common requests we see. It opens up the room, increases safety, and is far more practical for a busy lifestyle. However, a conversion involves more than simply swapping fixtures. Understanding the process and cost factors helps ensure a smooth renovation without unexpected surprises.
Plumbing and Drain Changes in a Tub-to-Shower Conversion
The most significant factor in a tub-to-shower conversion is what is happening underneath the floor. Most standard bathtubs use a 1.5-inch drain line, while building codes in Michigan typically require a 2-inch drain line for walk-in showers.
This allows water to drain more efficiently and prevents overflow onto your bathroom floor. In many cases, the drain must also be repositioned, since tubs often have end drains while showers typically use centered drains for proper pitch.
These updates require opening the subfloor and making precise adjustments. While standard for experienced installers, this step is what separates a simple upgrade from a full conversion.
Best Materials for a Walk-In Shower
The material you choose impacts both the total cost and long-term maintenance of your shower. Most homeowners choose from three main options:
- Acrylic surrounds
Non-porous and grout-free, these are low maintenance, cost-effective, and quick to install. - Traditional tile
Offers a custom, high-end look but requires more labor, waterproofing, and ongoing grout maintenance. - Natural or composite stone
A premium option that adds resale value and visual impact, but comes with higher cost and specific care requirements.
Many homeowners choose high-quality shower surrounds for the balance of appearance, durability, and easy upkeep.
How Long a Tub-to-Shower Conversion Takes
While some advertisements promise one-day bathroom upgrades, a true tub-to-shower conversion typically takes longer when done correctly.
Most projects take between two and four days:
- Day 1: Demolition, removal of the old tub, inspection for water damage, and plumbing updates
- Days 2–3: Installation of the shower base, wall system, and fixtures
- Final Step: Custom glass door installation, if selected
Taking the time to properly waterproof and install each component is critical, especially in Michigan where humidity and temperature changes can impact materials over time.
Average Cost Factors for Tub-to-Shower Conversions
The cost of a conversion varies based on several factors. A standard project typically includes removal of the tub, installation of a new shower base, wall system, valve, and basic hardware.
Costs can increase depending on upgrades such as:
- Built-in seating
- Recessed shelving or storage niches
- High-end or custom glass doors
- Repairs to subflooring or framing due to hidden damage
Investing in a quality conversion is not just about appearance. It improves functionality, safety, and long-term home value. Working with an experienced local team also ensures proper installation and reliable warranty coverage.
