What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its surround and drain assembly — is removed and replaced with a custom-fitted shower unit. The scope of the project depends on your existing bathroom layout, your finish selections, and whether you plan to expand the shower's square footage beyond the original tub's space.
On a mechanical level, the process involves rerouting the existing tub drain and supply lines, lifting the tub unit and any surrounding wall material that was tied to it, then constructing the new shower base with a correct slope toward the drain. New waterproof liner is installed before any surface covering goes in. Plumbing is adjusted to fit the new showerhead height and any body sprays, handheld wands, or rain heads you add.
The result is a fully waterproofed shower that drains correctly for the long term. A tub to shower conversion done correctly is not just a visual change — it is a fundamental upgrade to your bathroom's structure and usability.
Major Benefits of a Tub to Shower Conversion
- More Usable Bathroom Area — Standard bathtubs take up between 13 and 16 square feet. Converting to a curbless shower restores that area to usable, open bathroom space.
- Better Mobility Access — A tub to shower conversion can include a zero-entry design, grab bars, and a shower bench to assist those who need a safer bathing solution.
- Quicker Showers — The majority of adults shower far more often than they bathe. A tub to shower conversion redesigns your layout with how you spend your time.
- Higher Resale Value — Updated bathrooms consistently rank among the highest-ROI upgrades for resale. A tub to shower conversion signals modern, move-in-ready conditions to real estate agents.
- Easier Cleaning — Shower surrounds and bases are generally easier to scrub and wipe down than a full-length bathtub with grout lines on all four sides.
- Tailored Aesthetic Selections — From large-format porcelain tiles to frameless glass doors, a tub to shower conversion opens up significantly broader design directions than a prefab tub kit.
- Lower Utility Bills — Filling a bathtub consumes roughly 30 to 50 gallons of water per session. A low-flow showerhead installed during a tub to shower conversion can cut that to under 20 gallons per shower.
- Long-Term Durability — When our crew completes a tub to shower conversion, the waterproofing, substrate, and finish materials are designed for durability well beyond 20 years.
The Tub to Shower Conversion Procedure Step by Step
- Project Assessment and Design — A remodeling specialist meets with you on-site to measure your existing tub, plumbing, and bathroom layout. We discuss your must-haves and finish choices so the scope of work aligns with exactly what you have in mind.
- Removal of the Existing Tub and Surround — The existing fixtures and surrounding structure are taken out. Existing water supply tied to the old tub are properly shut off to make room for the new shower plumbing layout.
- Building the Shower's Foundation — This is widely considered the most technically demanding stage of a tub to shower conversion. New moisture-resistant substrate is attached to the framing, and a continuous waterproof layer is applied across every area that will contact water. The drain area is pitched properly to avoid standing water.
- Setting Valves, Drains, and Supply Lines — Licensed plumbers or our experienced crew install the new shower valve, drain body, and supply lines according to your design plan. Whether you chose a basic or premium shower setup, everything is installed at this stage.
- Tile, Stone, or Panel Installation — Our finish crew apply your preferred wall and floor covering using appropriate mortar, grout, and setting materials. Every grout joint is grouted and inspected before the enclosure goes in.
- Installing the Shower Enclosure — Depending on your preference, we hang your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. Every mounting bracket is set into the tile or framing to prevent loosening over time.
- Quality Check and Project Sign-Off — Once everything is finished and installed, we conduct a thorough quality review. Every seam at the perimeter are finished with professional-grade caulk. We show you the finished shower and make sure everything looks and functions as planned.
Who Is a Strong Candidate for a Tub to Shower Conversion?

Getting rid of the old tub and installing a more compact shower footprint can open up the entire room. Keep in mind, if your property has no other tub, maintaining a soaking option is something to weigh carefully before scheduling demolition.
