Considering a Tub to Shower Conversion? Read This First
A thoughtfully designed tub to shower conversion can fundamentally transform how you use your bathroom every single morning. For many homeowners, the standard bathtub occupies valuable floor space while sitting empty for months at a time. A tub to shower conversion swaps out that underused tub with a spacious walk-in shower that matches the way you actually bathe.
Brother & Brother Builders has dedicated years helping San Jose, CA homeowners plan and finish bathroom remodeling projects that stand the test of time. A tub to shower conversion is one of the most requested services we handle, and for obvious reasons — it creates real, lasting improvement without a full bathroom gut renovation.
Whether you are updating an outdated space or simply need a more efficient shower setup, this article walks you through the full picture — from how the conversion works to what marks someone an perfect candidate. Read on to find out whether a tub to shower conversion is the right move for your bathroom.
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 surround and plumbing fixtures — is removed and replaced with a custom-fitted shower unit. The scale of the project is shaped by your existing bathroom plumbing configuration, your finish selections, and whether you plan to expand the shower's square footage beyond the original tub's location.
On a structural level, the project involves rerouting the existing tub drain and supply lines, taking out the tub itself and any tile, drywall, or backer board that was tied to it, then constructing the new shower base with a correct slope toward the shower drain. New moisture barrier is applied before any finish material goes in. Plumbing is modified to accommodate the new showerhead location and any body sprays, handheld wands, or rain heads you choose.
The finished product is a fully waterproofed shower that drains correctly for decades. A tub to shower conversion done by experienced hands is not just a visual change — it is a complete upgrade to your bathroom's infrastructure and finish.
Top 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 curbless shower frees up that room to usable, open bathroom space.
- Aging-in-Place Functionality — A tub to shower conversion can incorporate a barrier-free floor transition, support handles, and a shower bench to accommodate aging adults, people with disabilities, or anyone recovering from surgery.
- More Efficient Daily Bathing — A large portion of homeowners shower far more often than they bathe. A tub to shower conversion redesigns your layout with how you really live.
- Better Return on Investment — Updated bathrooms consistently rank among the highest-ROI upgrades for resale. A tub to shower conversion signals modern, move-in-ready conditions to future owners.
- Lower Maintenance Demands — Shower surrounds and bases are generally easier to scrub and wipe down than a standard bathtub with grout lines on all four sides.
- Personalized Finish Choices — From natural stone slabs to frameless glass doors, a tub to shower conversion creates room for significantly broader design options than a prefab tub kit.
- Reduced Water Use — Running a full bath 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 builds a tub to shower conversion, the underlying systems are constructed to hold up for decades.
The Tub to Shower Conversion Procedure Step by Step
- In-Home Evaluation and Scope Review — A remodeling specialist visits your home to evaluate your existing tub, plumbing, and bathroom layout. We discuss your must-haves and finish choices so the project plan matches exactly what you want.
- Removal of the Existing Tub and Surround — The existing tub unit and wall material are taken out. Supply and drain lines 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 arguably the most important stage of a tub to shower conversion. New waterproof backer material is screwed to the structural framing, and a industry-standard moisture barrier 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 position 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 roughed in at this phase.
- Applying Your Chosen Finish Materials — Our finish crew apply your preferred wall and floor covering using professional-grade installation materials. Every seam is sealed and inspected before the enclosure goes in.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your design choice, we mount your shower door or curtain hardware. All hardware is secured correctly to provide a solid, long-lasting result.
- Final Inspection, Grouting, and Caulking — Once all surfaces is complete, we perform a careful quality review. All caulk joints at the perimeter are caulked with mold-resistant silicone caulk. We review with you the completed project and confirm everything meets your expectations.
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 is especially relevant for homeowners who struggle with high tub walls — a curbless or low-threshold shower is among the most meaningful accessibility changes you can add to your bathroom. Households with small kids who previously needed the tub for bathing little ones may also benefit once the youngest family members are shower-age.
A tub to shower conversion also makes sense for people dealing with a cramped layout where the tub consumes the floor plan. Getting rid of the old tub and putting in a custom shower can open up the entire room. Keep in mind, if your home only has one bathroom, keeping at least one bathtub is worth discussing before moving forward.
Homeowners who get the most out of 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 wanting a polished, move-in-ready space. Our team at Brother & Brother Builders will always be honest if a tub to shower conversion is not the right fit for your specific layout.
