Thinking About a Tub to Shower Conversion? Start Here
A well-planned tub to shower conversion can fundamentally transform how you use your bathroom every single day. For many homeowners, the standard bathtub takes up valuable floor space while collecting dust for months at a time. A tub to shower conversion trades in that underused tub with a functional walk-in shower that fits the way you actually live.

A tub to shower conversion is one of the most requested services we provide, and for clear purposes — it provides real, lasting improvement without a complete room overhaul.
Whether you are updating an outdated space or simply need a more modern shower setup, this overview walks you through the full picture — from how the project works to what marks someone an great candidate. Read on 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 bathroom remodeling service in which an existing bathtub — along with its enclosure and plumbing fixtures — is demolished and replaced with a custom-fitted shower unit. The complexity of the project varies based on your existing bathroom plumbing configuration, your finish selections, and whether you need to expand the shower's square footage beyond the original tub's position.
On a technical level, the project involves capping the existing tub drain and supply lines, taking out the tub shell and any old tile surround that was tied to it, then building out the new shower floor with a code-compliant slope toward the drain. New waterproofing membrane is installed before any tile, stone, or prefab panel goes in. Plumbing is modified to serve the new showerhead height and any extra spray features you choose.
The finished product is a fully waterproofed shower that functions properly for the long term. A tub to shower conversion done right is not just a surface-level change — it is a complete improvement to your bathroom's plumbing, waterproofing, and layout.
Major Benefits of a Tub to Shower Conversion
- Reclaimed Floor Space — Standard bathtubs take up between 13 and 16 square feet. Converting to a walk-in shower frees up that area to usable, open bathroom space.
- Aging-in-Place Functionality — A tub to shower conversion can include 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 redesigns your layout with how you actually use it.
- Stronger Home Appraisals — 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 pans, walls, and glass enclosures are generally easier to scrub and wipe down than a full-length bathtub with grout lines on all four sides.
- Custom Design Options — From natural stone slabs to semi-frameless enclosures, a tub to shower conversion creates room for significantly broader design possibilities than a prefab tub kit.
- Lower Utility Bills — Soaking in a tub uses roughly 30 to 50 gallons of water per use. A low-flow showerhead installed during a tub to shower conversion can cut that to significantly less water per session.
- Lasting Construction — When Brother & Brother Builders completes a tub to shower conversion, the waterproofing, substrate, and finish materials are built to last 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 evaluate your existing space and infrastructure. We discuss your wishlist and timeline so the project plan aligns with exactly what you have in mind.
- Demolition and Removal — The existing tub unit and wall material are taken out. Supply and drain lines tied to the old tub are properly shut off to make room for the updated fixture configuration.
- Framing, Waterproofing, and Substrate Work — This is widely considered the most technically demanding stage of a tub to shower conversion. New moisture-resistant substrate is screwed to the framing, and a continuous waterproof layer is rolled or troweled on across the shower floor and lower walls. The drain area is pitched properly to prevent pooling.
- Plumbing Rough-In and Fixture Placement — Skilled tradespeople on our crew set the new plumbing fixtures according to your design plan. Whether you chose a standard showerhead or an upgraded fixture package, everything is positioned at this stage.
- Finishing the Shower Walls and Floor — Our finish crew set your chosen wall tile, floor tile, or solid surface panels using professional-grade installation materials. Every seam is sealed and inspected before glass or curtain hardware is installed.
- Installing the Shower Enclosure — Depending on your design choice, we mount your chosen enclosure system. Every mounting bracket is set into the tile or framing to provide a solid, long-lasting result.
- Quality Check and Project Sign-Off — Once everything is tiled, grouted, and enclosed, we conduct a thorough quality review. Each transition joint at the base and wall corners are sealed with professional-grade caulk. We walk you through the final result and make sure everything looks and functions as planned.
Who Is a Strong Candidate for a Tub to Shower Conversion?
Anyone who finds the existing tub more of an obstacle than an asset are typically ideal candidates a tub to shower conversion. This also applies to aging adults or people with mobility limitations — a zero-entry walk-in shower is among the most meaningful accessibility changes you can invest in for your bathroom. Families with young children who previously needed the tub for young children's hygiene routines may want to reconsider timing once the youngest family members are past the bathtub stage.

Removing the tub and installing a more compact shower footprint can dramatically improve the sense of space. Keep in mind, if your home only has one bathroom, preserving a full bath somewhere in the home is a conversation we always have with clients before committing.
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 wanting a polished, move-in-ready space. Our experts at Brother & Brother Builders will tell you plainly if a tub to shower conversion is not the best call for your specific layout.
