Considering a Tub to Shower Conversion? Read This First
A well-planned tub to shower conversion can dramatically improve how you use your bathroom every single morning.

A tub to shower conversion is among our most popular services we offer, and for clear purposes — it delivers real, lasting improvement without a full bathroom gut renovation.
Whether you are aging in place or simply prefer a more accessible shower setup, this overview walks you through all the details — from how the conversion works to what qualifies someone an great candidate. Let's get started to find out whether a tub to shower conversion is the best option for your space.
What Exactly 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 demolished and replaced with a purpose-built shower unit. The scope of the project depends on your existing bathroom layout, your design preferences, and whether you plan to expand the shower's footprint beyond the original tub's space.
On a structural level, the process involves rerouting the existing tub drain and supply lines, taking out the tub unit and any tile, drywall, or backer board that was tied to it, then constructing the new shower base with a code-compliant slope toward the shower drain. New waterproof liner is applied before any tile, stone, or prefab panel goes on. Plumbing is rerouted to fit the new showerhead height and any additional fixtures you add.
The result is a fully waterproofed shower that drains correctly for decades. A tub to shower conversion done correctly is not just a cosmetic change — it is a complete improvement to your bathroom's plumbing, waterproofing, and layout.
Key Benefits of a Tub to Shower Conversion
- Reclaimed Floor Space — Standard bathtubs occupy between 13 and 16 square feet. Converting to a curbless shower restores that room to usable, accessible bathroom space.
- Aging-in-Place Functionality — A tub to shower conversion can feature a zero-entry design, safety rails, and a shower bench to assist aging adults, people with disabilities, or anyone recovering from surgery.
- Quicker Showers — A large portion of homeowners shower much more frequently than they bathe. A tub to shower conversion redesigns your layout with how you really live.
- Higher Resale Value — 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.
- Lower Maintenance Demands — Shower pans, walls, and glass enclosures are generally easier to scrub and wipe down than a deep-soaking bathtub with hard-to-reach corners.
- Personalized Finish Choices — From natural stone slabs to heavy-duty shower curtain systems, a tub to shower conversion unlocks significantly broader design directions than a standard tub surround.
- Lower Utility Bills — Soaking in a tub requires roughly 30 to 50 gallons of water per bath. A water-efficient shower fixture installed during a tub to shower conversion can cut that to as little as 15 gallons.
- Lasting Construction — When Brother & Brother Builders completes a tub to shower conversion, the waterproofing, substrate, and finish materials are designed for durability for decades.
The Tub to Shower Conversion Procedure Step by Step
- In-Home Evaluation and Scope Review — A remodeling specialist visits your home to assess your existing fixtures and framing. We discuss your wishlist and timeline so the scope of work matches exactly what you need.
- Demolition and Removal — The existing tub unit and wall material are demolished and cleared. Existing water supply tied to the old tub are properly shut off to prepare for the new shower plumbing layout.
- Structural Prep and Moisture Barrier Installation — This is arguably the most important stage of a tub to shower conversion. New waterproof backer material is fastened to the wall studs, and a industry-standard moisture barrier is installed across the shower floor and lower walls. The shower pan is graded toward the drain to avoid standing water.
- Installing New Shower Plumbing — Licensed plumbers or our experienced crew set the new shower valve, drain body, and supply lines according to your design plan. Whether you went with a basic or premium shower setup, everything is installed at this stage.
- Applying Your Chosen Finish Materials — Our finish crew set your preferred wall and floor covering using professional-grade installation materials. Every tile edge is sealed and checked before the enclosure goes in.
- Hanging Doors, Glass, or Hardware — Depending on your preference, we mount your shower door or curtain hardware. All hardware is secured correctly to prevent loosening over time.
- Quality Check and Project Sign-Off — Once everything is complete, we conduct a room-by-room quality review. Every seam at the base and wall corners are sealed with mold-resistant silicone caulk. We show you the finished shower and confirm everything looks and functions as planned.
Who Is a Suitable Candidate for a Tub to Shower Conversion?
Anyone who finds the existing tub more of an obstacle than an asset are usually perfect for a tub to shower conversion. This also applies to aging adults or people with mobility limitations — a curbless or low-threshold shower is a genuinely life-improving accessibility modifications you can make to your bathroom. Households with small kids who previously needed the tub for young children's hygiene routines may want to reconsider timing once those children are shower-age.
A tub to shower conversion also makes sense for homeowners in smaller bathrooms where the tub monopolizes the room layout. Eliminating the bathtub and replacing it with a right-sized walk-in shower can dramatically improve the sense of space. However, if your property has no other tub, maintaining a soaking option is something to weigh carefully before moving forward.
Candidates who benefit most from a tub to shower conversion are those committed to a bathroom that works for years ahead as well as those getting ready to list and needing a fresh, buyer-ready bathroom. Our team at our firm will always be honest if a tub to shower conversion is not in your best interest for your specific layout.
