Walk-In Shower Installation: Walk-In Shower vs. Tub-to-Shower Conversion

Rick Musto • October 14, 2025
Walk-In Shower Installation


You're ready to replace that old bathtub, but should you go with a walk-in shower installation or a tub-to-shower conversion? This decision affects your daily routine, home functionality, and long-term comfort. The answer depends on your family's specific needs and how you actually use your bathroom.


Find the Best Shower Solution for Your Lifestyle


Choose walk-in shower installation if:


  • You're planning to age in place
  • Mobility or accessibility is a concern
  • You rarely or never take baths
  • You have other bathtubs in your home
  • You want a modern, spa-like aesthetic


Choose tub-to-shower conversion if:


  • You have an unused bathtub taking up space
  • You want improved functionality on a budget
  • You're working within the existing footprint
  • You need a quick bathroom update


Keep your bathtub if:


  • You have young children who need baths
  • It's your only bathroom
  • You actually enjoy taking baths


Understanding the Difference Between Shower Options


A walk-in shower is barrier-free or low-threshold with no bathtub component, offering open access and maximum customization.


A tub-to-shower conversion replaces your existing bathtub with a shower unit in the same footprint. While it can include low-step entry, it's different from a true walk-in shower.


Your bathroom serves your family for 10 to 20+ years after renovation. The right choice enhances functionality now while accommodating future needs.


Walk-In Showers: Benefits, Features, and Considerations


What It Is: Zero-threshold or minimal-threshold entry with no bathtub. Creates an open, spacious feel in various sizes to fit your layout.


Key Benefits:


  • Maximum accessibility: Barrier-free entry accommodates wheelchairs and makes aging in place safer, key accessibility shower options for long-term comfort
  • Easier maintenance: No tub edges or hard-to-reach corners
  • Modern aesthetic: Spa-like atmosphere with clean lines
  • Luxury features: Rainfall showerheads, body sprays, built-in benches, custom niches
  • Better space utilization: Opens up your bathroom visually and functionally


Best For: Master bathrooms when you have other bathrooms with tubs. Ideal for homeowners who prioritize accessibility shower options, prefer showers over baths, or are planning for long-term mobility needs.


What to Consider: May affect resale value if it's your only bathroom. Requires a proper drainage slope and professional walk-in shower installation. Eliminates the bath option entirely.


Key Advantages of a Tub-to-Shower Conversion


What It Is: Replaces your existing bathtub with a shower unit in the same footprint, utilizing existing plumbing.


Key Benefits:


  • Faster installation: Completes in 1-3 days typically
  • Budget-friendly: Lower shower conversion cost than full remodeling while improving functionality
  • Accessibility options: Low-threshold entries and grab bars available
  • Smart compromise: Good solution when you have other tubs in the home


Best For: Guest bathrooms, secondary bathrooms, or unused tubs wasting space. Ideal for quick updates or working within a tighter budget.


What to Consider: Still has a step, even if minimal. Limited by the existing tub's footprint, restricting design flexibility.


Comparing Walk-In Showers and Bathtubs: Time, Cost, and Features


Installation Time:


  • Walk-in: 2 to 5 days
  • Conversion: 1 to 3 days


Cost:


  • Walk-in: Higher (custom design, potential layout changes)
  • Conversion: More budget-friendly shower conversion cost (uses existing space)


Accessibility:


  • Walk-in: Maximum, barrier-free
  • Conversion: Good with low-threshold options


Design Flexibility:


  • Walk-in: Extensive customization
  • Conversion: Limited by existing footprint


Smart Tips: What to Do (and Not Do) When Updating Your Bathroom


Don't:


  • Remove your only bathtub without considering resale impact
  • Choose based on trends alone, consider your actual bathing habits
  • Ignore future needs when evaluating the walk-in shower vs bathtub decision
  • Skip proper waterproofing for either option


Do:


  • Assess your household honestly (when did anyone last use that tub?)
  • Think long-term about how many years you'll stay
  • Consider your whole house and other bathrooms with tubs
