Cost to Convert a Bathtub to a Walk-In Shower
Converting a bathtub to a walk-in shower means removing the existing tub, changing the plumbing for the new shower layout, installing a shower frame or conversion kit, and waterproofing and sealing the finished area. Homeowners commonly take on this bathroom upgrade when the tub is worn or damaged or when they want a different shower setup, but the plumbing and waterproofing work make it a hard project.

Common reasons homeowners do this job
- The existing bathtub is worn or damaged.

DIY or call a pro?
This is a legitimate DIY project, but it is hard and a professional is worth considering when plumbing modifications or waterproofing feel uncertain. Improper plumbing or waterproofing can cause significant water damage. Shut off the bathroom water supply completely before starting, and wear safety glasses and gloves during demolition.
Frequently asked questions
- Can I convert my bathtub to a walk-in shower myself?
- Yes, but expect a hard project with demolition, plumbing changes, waterproofing, fixture installation, and joint sealing. Consider professional help if you are unsure about modifying plumbing or creating the waterproof barrier; those are the areas where mistakes can lead to water damage.
- What makes a bathtub-to-walk-in-shower conversion cost more?
- The price can rise with the job size, labor time, and materials, including the conversion kit, waterproofing materials, plumbing supplies, fixtures, glass door, and sealant. Removing and disposing of the old tub and surrounding material can also add work, while a small job may carry a minimum or trip charge.
- What should I check before choosing a walk-in shower conversion kit?
- Measure the existing bathtub area first, then select a shower design or pre-fabricated conversion kit that fits the available space. Check the existing plumbing layout as well, since the new shower configuration may require modifications.
- How can I help prevent leaks after the conversion?
- Apply a waterproof barrier to the shower walls and floor, then seal all joints and edges. Improper plumbing or waterproofing can lead to significant water damage, even after the shower is installed.
