Keep reading to see whether a tub to shower conversion is the right move for your space.

What Really Is a Tub to Shower Conversion?

A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its surround and drain assembly — is removed and replaced with a professionally installed shower unit. The scale of the project varies based on your existing bathroom footprint, your finish selections, and whether you plan to expand the shower's square footage beyond the original tub's position.

On a structural level, the process involves disconnecting the existing tub drain and supply lines, taking out the tub unit and any old tile surround that was tied to it, then framing the new shower floor with a proper slope toward the center drain. New moisture barrier is installed before any surface covering goes in. Plumbing is rerouted to fit the new showerhead location and any additional fixtures you choose.

The finished product is a fully waterproofed shower that functions properly for many years. A tub to shower conversion done correctly is not just a visual change — it is a fundamental improvement to your bathroom's structure and usability.

Top Benefits of a Tub to Shower Conversion

• Better Use of Square Footage — Standard bathtubs consume between 13 and 16 square feet. Converting to a custom shower stall returns that area to usable, accessible bathroom space.
• Better Mobility Access — A tub to shower conversion can incorporate a low-threshold or curbless entry, support handles, and a fold-down bench to accommodate those who need a safer bathing solution.
• Quicker Showers — The majority of adults shower much more frequently than they bathe. A tub to shower conversion matches your space with how you spend your time.
• Better Return on Investment — Updated bathrooms reliably appear among the highest-ROI upgrades for resale. A tub to shower conversion communicates updated finishes to future owners.
• Easier Cleaning — Shower surrounds and bases are typically faster to scrub and wipe down than a full-length bathtub with a surrounding tile enclosure.
• Custom Design Options — From large-format porcelain tiles to heavy-duty shower curtain systems, a tub to shower conversion opens up significantly broader design possibilities than a standard tub surround.
• Reduced Water Use — Filling a bathtub requires roughly 30 to 50 gallons of water per session. A modern shower valve installed during a tub to shower conversion can lower usage to significantly less water per session.
• Structural Longevity — When our crew completes a tub to shower conversion, the waterproofing, substrate, and finish materials are designed for durability through years of daily use.

The Tub to Shower Conversion Procedure Step by Step

1. Initial Consultation and Planning — A remodeling specialist visits your home to evaluate your existing space and infrastructure. We review your must-haves and finish choices so the project plan aligns with exactly what you need.
2. Tub Extraction and Teardown — The existing tub unit and wall material are carefully removed. Supply and drain lines tied to the old tub are properly shut off to make room for the new shower plumbing layout.
3. Framing, Waterproofing, and Substrate Work — This is arguably the most important stage of a tub to shower conversion. New moisture-resistant substrate is screwed to the wall studs, and a continuous waterproof layer is installed across the shower floor and lower walls. The drain area is sloped correctly to avoid standing water.
4. Plumbing Rough-In and Fixture Placement — Licensed plumbers or our experienced crew set the new shower valve, drain body, and supply lines according to your design plan. Whether you selected a single overhead rain head, a handheld wand, or a multi-function valve system, everything is positioned at this point.
5. Applying Your Chosen Finish Materials — Skilled installers set your preferred wall and floor covering using professional-grade installation materials. Every tile edge is grouted and reviewed before glass or curtain hardware is installed.
6. Hanging Doors, Glass, or Hardware — Depending on your selected style, we install your shower door or curtain hardware. All hardware is set into the tile or framing to prevent loosening over time.
7. Final Inspection, Grouting, and Caulking — Once everything is tiled, grouted, and enclosed, we do a careful final inspection. Every seam at the base and wall corners are sealed with mold-resistant silicone caulk. We review with you the final result and verify everything looks and functions as planned.

Who Is a Suitable Candidate for a Tub to Shower Conversion?

Homeowners who rarely or never use their bathtub are usually perfect for a tub to shower conversion.
