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 framing and plumbing fixtures — is taken out and replaced with a custom-fitted shower unit. The scale of the project depends on your existing bathroom footprint, your style choices, and whether you want to expand the shower's square footage beyond the original tub's position.

On a technical level, the process involves rerouting the existing tub drain and supply lines, taking out the tub itself and any surrounding wall material that was tied to it, then framing the new shower floor with a code-compliant slope toward the center drain. New waterproofing membrane is laid down before any finish material goes in. Plumbing is modified to accommodate the new showerhead position and any extra spray features you select.

The finished product is a fully waterproofed shower that performs reliably for many years. A tub to shower conversion done by experienced hands is not just a cosmetic change — it is a complete improvement to your bathroom's infrastructure and finish.

Major Benefits of a Tub to Shower Conversion

• More Usable Bathroom Area — Standard bathtubs consume between 13 and 16 square feet. Converting to a walk-in shower frees up that room to usable, accessible bathroom space.
• Better Mobility Access — A tub to shower conversion can feature a barrier-free floor transition, safety rails, and a fold-down bench to support aging adults, people with disabilities, or anyone recovering from surgery.
• Quicker Showers — Most people shower significantly more 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 top home improvements for resale. A tub to shower conversion communicates updated finishes to prospective buyers.
• Lower Maintenance Demands — Shower surrounds and bases are often simpler to clean and maintain than a full-length bathtub with hard-to-reach corners.
• Tailored Aesthetic Selections — From large-format porcelain tiles to frameless glass doors, a tub to shower conversion creates room for significantly broader design options than a prefab tub kit.
• Reduced Water Use — Filling a bathtub uses roughly 30 to 50 gallons of water per use. A modern shower valve installed during a tub to shower conversion can cut that to under 20 gallons per shower.
• Structural Longevity — When Brother & Brother Builders completes a tub to shower conversion, the underlying systems are designed for durability for decades.

The Tub to Shower Conversion Project Step by Step

1. Project Assessment and Design — A project consultant meets with you on-site to evaluate your existing space and infrastructure. We discuss your must-haves and finish choices so the project plan matches exactly what you want.
2. Tub Extraction and Teardown — The existing bathtub, tub surround, and any damaged or outdated backer board are carefully removed. Any plumbing connections tied to the old tub are disconnected, capped, or rerouted to make room for the updated fixture configuration.
3. Structural Prep and Moisture Barrier Installation — This is arguably the most critical stage of a tub to shower conversion. New waterproof backer material is fastened to the framing, and a industry-standard moisture barrier is applied across every area that will contact water. The floor base is graded toward the drain to avoid standing water.
4. Installing New Shower Plumbing — Our plumbing team position the new shower valve, drain body, and supply lines according to your fixture selections. Whether you chose a basic or premium shower setup, everything is installed at this point.
5. Finishing the Shower Walls and Floor — Tile setters apply your selected finish material using appropriate mortar, grout, and setting materials. Every tile edge is finished and reviewed before moving to the next phase.
6. Hanging Doors, Glass, or Hardware — Depending on your design choice, we hang your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. All hardware is set into the tile or framing to prevent loosening over time.
7. Quality Check and Project Sign-Off — Once all surfaces is finished and installed, we conduct a careful walk-through. Every seam at corners and the floor-to-wall transition are sealed with professional-grade caulk. We walk you through the final result and confirm everything is exactly what you wanted.
