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 hardware — is removed and replaced with a custom-fitted shower unit. The scale of the project is shaped by your existing bathroom footprint, your design preferences, and whether you plan to expand the shower's footprint beyond the original tub's position.
On a technical level, the work 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 constructing the new shower pan with a proper slope toward the shower drain. New waterproof liner is laid down before any finish material goes on. Plumbing is modified to fit the new showerhead height and any body sprays, handheld wands, or rain heads you select.
The result is a code-compliant shower that drains correctly for decades. A tub to shower conversion done right is not just a visual change — it is a thorough improvement to your bathroom's infrastructure and finish.
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.

- Quicker Showers — A large portion of homeowners shower much more frequently than they bathe. A tub to shower conversion aligns your bathroom with how you actually use it.
- Stronger Home Appraisals — Updated bathrooms consistently rank among the most valued renovations for resale. A tub to shower conversion tells buyers the home has been maintained to future owners.
- Simpler Upkeep — Shower floors and walls are generally easier to clean and maintain than a standard bathtub with grout lines on all four sides.
- Personalized Finish Choices — From large-format porcelain tiles to frameless glass doors, a tub to shower conversion opens up significantly broader design options than a standard tub surround.
- Lower Utility Bills — Soaking in a tub requires roughly 30 to 50 gallons of water per bath. A low-flow showerhead installed during a tub to shower conversion can lower usage to under 20 gallons per shower.
- Long-Term Durability — When Brother & Brother Builders builds a tub to shower conversion, the underlying systems are designed for durability for decades.
The Tub to Shower Conversion Process Step by Step
- Initial Consultation and Planning — A member of our team visits your home to measure your existing fixtures and framing. We go over your must-haves and finish choices so the proposal matches exactly what you want.
- Tub Extraction and Teardown — The existing bathtub, tub surround, and any damaged or outdated backer board are demolished and cleared. Existing water supply tied to the old tub are disconnected, capped, or rerouted to set the stage for the updated fixture configuration.
- Framing, Waterproofing, and Substrate Work — This is often the most technically demanding stage of a tub to shower conversion. New cement board or tile backer is fastened to the wall studs, and a continuous waterproof layer is applied across all wet surfaces. The shower pan is sloped correctly to ensure drainage.
- Setting Valves, Drains, and Supply Lines — Skilled tradespeople on our crew install the new rough-in plumbing according to your chosen layout. Whether you selected a single overhead rain head, a handheld wand, or a multi-function valve system, everything is installed at this stage.
- Applying Your Chosen Finish Materials — Tile setters set your selected finish material using professional-grade installation materials. Every tile edge is grouted and checked before the enclosure goes in.
- Installing the Shower Enclosure — Depending on your preference, we hang your chosen enclosure system. Each component is secured correctly to provide a solid, long-lasting result.
- Final Inspection, Grouting, and Caulking — Once the full shower is complete, we do a room-by-room quality review. Every seam at the base and wall corners are finished with professional-grade caulk. We walk you through the final result and verify everything is exactly what you wanted.
Who Is a Good Candidate for a Tub to Shower Conversion?
Homeowners who rarely or never use their bathtub are often the best fit a tub to shower conversion. This is especially relevant for aging adults or people with mobility limitations — a barrier-free shower conversion is one of the most impactful accessibility modifications you can add to your bathroom. Households with small kids who previously needed the tub for bathing little ones may also benefit once the kids are shower-age.

Eliminating the bathtub and replacing it with a right-sized walk-in shower can dramatically improve the sense of space.

Our crew at Brother & Brother Builders will always be honest if a tub to shower conversion is not the best call for your specific layout.
