What Actually Is a Tub to Shower Conversion?

A tub to shower conversion is a home renovation 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 scope of the project is shaped by your existing bathroom footprint, your finish selections, and whether you want to expand the shower's square footage beyond the original tub's space.

On a technical level, the process involves capping the existing tub drain and supply lines, lifting the tub itself and any old tile surround that was tied to it, then framing the new shower pan with a correct slope toward the drain. New waterproofing membrane is applied before any finish material goes in. Plumbing is rerouted to serve the new showerhead location and any body sprays, handheld wands, or rain heads you add.

The finished product is a fully waterproofed shower that performs reliably for decades. A tub to shower conversion done right is not just a visual change — it is a thorough transformation to your bathroom's infrastructure and finish.

Key Benefits of a Tub to Shower Conversion

• More Usable Bathroom Area — Standard bathtubs consume between 13 and 16 square feet. Converting to a curbless shower frees up that square footage to usable, navigable bathroom space.
• Improved Accessibility — A tub to shower conversion can include a low-threshold or curbless entry, safety rails, and a fold-down bench to assist homeowners with limited mobility.
• Faster Morning Routines — Most people shower much more frequently than they bathe. A tub to shower conversion matches your space with how you really live.
• Higher Resale Value — Updated bathrooms reliably appear among the highest-ROI upgrades for resale. A tub to shower conversion tells buyers the home has been maintained to future owners.
• Simpler Upkeep — Shower surrounds and bases are often simpler to scrub and wipe down than a full-length bathtub with a surrounding tile enclosure.
• Personalized Finish Choices — From large-format porcelain tiles to semi-frameless enclosures, a tub to shower conversion creates room for far more design options than a one-piece tub unit.
• Reduced Water Use — Soaking in a tub requires roughly 30 to 50 gallons of water per session. A low-flow showerhead 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 designed for durability for decades.

The Tub to Shower Conversion Procedure Step by Step

1. Project Assessment and Design — A member of our team meets with you on-site to assess your existing fixtures and framing. We go over your goals, design preferences, and budget so the proposal matches exactly what you want.
2. Removal of the Existing Tub and Surround — The existing fixtures and surrounding structure are carefully removed. Supply and drain lines tied to the old tub are properly shut off to make room for the revised drain placement.
3. Building the Shower's Foundation — This is often the most technically demanding stage of a tub to shower conversion. New moisture-resistant substrate is attached to the wall studs, and a full waterproofing membrane is installed across all wet surfaces. The floor base is pitched properly to avoid standing water.
4. Setting Valves, Drains, and Supply Lines — Skilled tradespeople on our crew position the new rough-in plumbing according to your chosen layout. Whether you went with a single overhead rain head, a handheld wand, or a multi-function valve system, everything is positioned at this point.
5. Applying Your Chosen Finish Materials — Our finish crew install your chosen wall tile, floor tile, or solid surface panels using the correct adhesive and grout system. Every grout joint is grouted and checked before the enclosure goes in.
6. Glass Enclosure, Door, or Curtain Rod Installation — Depending on your design choice, we hang your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. Each component is secured correctly to provide a solid, long-lasting result.
7. Quality Check and Project Sign-Off — Once everything is complete, we conduct a room-by-room quality review. Each transition joint at corners and the floor-to-wall transition are sealed with mold-resistant silicone caulk. We show you the final result and confirm everything looks and functions as planned.

Who Is a Strong Candidate for a Tub to Shower Conversion?
