Keep reading to see whether a tub to shower conversion is a smart choice for your space.
What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its enclosure and plumbing fixtures — is removed and replaced with a custom-fitted shower unit. The scale of the project varies based on your existing bathroom layout, your design preferences, and whether you need to expand the shower's footprint beyond the original tub's space.
On a technical level, the process involves capping 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 waterproofing membrane is laid down before any surface covering goes up. Plumbing is modified to serve the new showerhead height and any body sprays, handheld wands, or rain heads you add.
The finished product is a code-compliant shower that performs reliably for decades. A tub to shower conversion done right is not just a visual change — it is a thorough upgrade to your bathroom's infrastructure and finish.
Key Benefits of a Tub to Shower Conversion
- Better Use of Square Footage — Standard bathtubs take up between 13 and 16 square feet. Converting to a walk-in shower frees up that room to usable, accessible bathroom space.
- Improved Accessibility — A tub to shower conversion can feature a zero-entry design, grab bars, and a shower bench to support aging adults, people with disabilities, or anyone recovering from surgery.
- Quicker Showers — A large portion of homeowners shower far more often than they bathe. A tub to shower conversion matches your space with how you really live.
- Higher Resale Value — Updated bathrooms always show up among the highest-ROI upgrades for resale. A tub to shower conversion tells buyers the home has been maintained to real estate agents.
- Simpler Upkeep — Shower surrounds and bases are typically faster to clean and maintain than a deep-soaking bathtub with grout lines on all four sides.
- Custom Design Options — From subway tile surrounds to heavy-duty shower curtain systems, a tub to shower conversion creates room for far more design directions than a one-piece tub unit.
- Water Efficiency — Soaking in a tub consumes roughly 30 to 50 gallons of water per bath. A low-flow showerhead installed during a tub to shower conversion can cut that to under 20 gallons per shower.
- Long-Term Durability — When Brother & Brother Builders installs a tub to shower conversion, the underlying systems are designed for durability well beyond 20 years.
The Tub to Shower Conversion Process Step by Step
- Project Assessment and Design — A remodeling specialist comes to your bathroom to evaluate your existing space and infrastructure. We review your goals, design preferences, and budget so the proposal aligns with exactly what you need.
- Removal of the Existing Tub and Surround — The existing bathtub, tub surround, and any damaged or outdated backer board are taken out. Supply and drain lines tied to the old tub are properly shut off to prepare for the new shower plumbing layout.
- Framing, Waterproofing, and Substrate Work — This is widely considered the most important stage of a tub to shower conversion. New waterproof backer material is attached to the structural framing, and a continuous waterproof layer is rolled or troweled on across the shower floor and lower walls. The floor base is sloped correctly to prevent pooling.
- 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 selected a single overhead rain head, a handheld wand, or a multi-function valve system, everything is roughed in at this phase.
- Applying Your Chosen Finish Materials — Tile setters install your selected finish material using the correct adhesive and grout system. Every tile edge is sealed and inspected before glass or curtain hardware is installed.
- Hanging Doors, Glass, or Hardware — Depending on your preference, we mount your chosen enclosure system. Every mounting bracket is secured correctly to prevent loosening over time.
- Quality Check and Project Sign-Off — Once all surfaces is tiled, grouted, and enclosed, we conduct a thorough quality review. All caulk joints at the perimeter are finished with flexible waterproof sealant. We review with you the completed project 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. This is especially relevant for those who find stepping over a tub edge difficult or unsafe — a curbless or low-threshold shower is among the most meaningful accessibility modifications you can add to your bathroom. Households with small kids who previously needed the tub for bathing little ones may find value in a conversion once those children are old enough to shower independently.
A tub to shower conversion also is a smart move for anyone with a narrow or tight bathroom footprint where the tub consumes the room layout. Getting rid of the old tub and putting in a custom shower can dramatically improve the sense of space. That said, if your property has no other tub, preserving a full bath somewhere in the home is a conversation we always have with clients before scheduling demolition.
Those who see the greatest return from a tub to shower conversion are those planning to stay in the home long-term as well as those preparing to sell and looking for a bathroom that reads modern and updated. Our crew at our firm will give you a straight answer if a tub to shower conversion is not in your best interest for your home.
