The scope of the project varies based on your existing bathroom footprint, your finish selections, and whether you need to expand the shower's usable area beyond the original tub's space.
On a mechanical level, the process involves rerouting check here the existing tub drain and supply lines, removing the tub shell and any tile, drywall, or backer board that was tied to it, then building out the new shower base with a code-compliant slope toward the shower drain. New waterproof liner is laid down before any tile, stone, or prefab panel 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 structurally sound shower that performs reliably for many years. A tub to shower conversion done by experienced hands 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

- Better Mobility Access — A tub to shower conversion can incorporate a low-threshold or curbless entry, safety rails, and a built-in seat to support those who need a safer bathing solution.

- Higher Resale Value — Updated bathrooms consistently rank among the most valued renovations for resale. A tub to shower conversion signals modern, move-in-ready conditions to prospective buyers.
- Simpler Upkeep — Shower floors and walls are typically faster to clean and maintain than a standard bathtub with a surrounding tile enclosure.
- Personalized Finish Choices — From natural stone slabs to heavy-duty shower curtain systems, a tub to shower conversion creates room for many more design possibilities than a one-piece tub unit.
- Lower Utility Bills — Running a full bath uses roughly 30 to 50 gallons of water per session. A modern shower valve installed during a tub to shower conversion can reduce consumption to under 20 gallons per shower.
- Structural Longevity — When our team completes a tub to shower conversion, the waterproofing, substrate, and finish materials are constructed to hold up through years of daily use.
The Tub to Shower Conversion Procedure Step by Step
- Initial Consultation and Planning — A member of our team visits your home to assess your existing fixtures and framing. We discuss your wishlist and timeline so the project plan reflects exactly what you want.
- Demolition and Removal — The existing bathtub, tub surround, and any damaged or outdated backer board are carefully removed. Existing water supply tied to the old tub are properly shut off to make room for the new shower plumbing layout.
- Building the Shower's Foundation — This is widely considered the most critical stage of a tub to shower conversion. New waterproof backer material is screwed to the structural framing, and a full waterproofing membrane is rolled or troweled on across every area that will contact water. The shower pan is graded toward the drain to avoid standing water.
- Installing New Shower Plumbing — Skilled tradespeople on our crew set the new rough-in plumbing according to your fixture selections. Whether you went with a standard showerhead or an upgraded fixture package, everything is positioned at this stage.
- Applying Your Chosen Finish Materials — Our finish crew apply your preferred wall and floor covering using professional-grade installation materials. Every seam is finished and checked before the enclosure goes in.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your selected style, we mount your shower door or curtain hardware. Each component is set into the tile or framing to provide a solid, long-lasting result.
- Quality Check and Project Sign-Off — Once all surfaces is tiled, grouted, and enclosed, we do a room-by-room final inspection. All caulk joints at corners and the floor-to-wall transition are caulked with professional-grade caulk. We show you the finished shower and make sure everything meets your expectations.
Who Is a Strong Candidate for a Tub to Shower Conversion?
Homeowners who rarely or never use their bathtub are typically ideal candidates a tub to shower conversion. This also applies to homeowners who struggle with high tub walls — a curbless or low-threshold shower is one of the most impactful accessibility upgrades you can add to your bathroom. Households with small kids who previously needed the tub for young children's hygiene routines may find value in a conversion once those children are past the bathtub stage.

Removing the tub and installing a more compact shower footprint can open up the entire room. That said, if your household has young children who regularly take baths, maintaining a soaking option is a conversation we always have with clients before moving forward.

Our team at Brother & Brother Builders will give you a straight answer if a tub to shower conversion is not the best call for your particular situation.
