Walk-in shower conversions are like giving your bathroom a gym membership and a spa day at the same time—more room to move, less to scrub, and a look that says “today’s the day I actually enjoy getting ready.” If you’re staring at a fiberglass tub you never use, this guide will make your next step simple (and fun). We’ll cover costs, materials, and the best fixtures—plus brand picks we love for Houston homes. If you want hands-on help, start with a trusted local bathroom remodeling company.
Explanation of walk-in shower conversions
A tub-to-shower conversion swaps a bathtub for a spacious, easy-to-access shower. The big wins: accessibility (low/zero threshold), cleanability (fewer grout lines), and style (think “spa” not “builder basic”). It’s the most-requested upgrade we see.
Importance of selecting the suitable materials and fixtures
Showers work hard every day. Picking durable, low-maintenance surfaces and reliable fixtures makes the fun part (the look) last longer. We’re fans of grout-free Onyx walls and Delta Faucets—stone looks without the scrubbing, and parts you can actually get in five years.
Can a fiberglass tub be converted into a walk-in shower?
Yes—and it’s the most common conversion we do. The basics: remove the tub, adjust plumbing, install a properly sloped pan with a 2″ drain, then add walls (tile or grout-free panels), glass, and fixtures. For walls, non-porous options like Onyx Collection or BCI Acrylic look like stone and clean in minutes.
How much does converting a bathtub to a walk-in shower cost?
Scope, finishes, glass style, and any framing/electrical changes all affect price. Most Houston-area conversions land around $11,000–$16,000 for a quality build; custom features (multiple heads, built-in seating, luxury glass) raise the number.
A conversion is also an investment: National Association of Realtors data shows walk-in showers add buyer appeal; many homes see a resale lift (~$2,500+) while you enjoy the upgrade daily.
Is a tub-to-shower conversion worth it?
For most households: yes. Benefits include safer entry/exit, a bigger-feeling bath, fast cleaning, and a modern look. Add optional bench + grab bars for future-proof comfort (we block walls for bars even if you don’t install them now).
Is replacing a tub with a walk-in shower a good idea?
If you’re staying long-term, absolutely. If you plan to sell soon, keep one tub somewhere in the home—buyers with kids tend to want at least one. Either way, the conversion bath should feel intentional: consistent finishes, layered lighting, and a layout that suits your routine.
Is it possible to tile over a fiberglass shower?
Technically possible in a few cases—but usually not recommended. Tile needs a stable, properly prepared substrate. If you want tile, it’s typically smarter to replace the fiberglass with backer + KERDI or switch to Onyx/BCI panels for the look of stone without grout.
Which is cheaper, a walk-in tub or a walk-in shower?
Basic walk-in showers usually cost less than walk-in tubs. Tubs often require more plumbing (and sometimes electrical), and premium hydrotherapy models climb quickly in price. If soaking is rare, a shower gives you everyday value and more space.
Is fiberglass or acrylic better for a walk-in shower?
Acrylic generally wins for durability and maintenance. Fiberglass is affordable and easy to install, but it can discolor and crack more readily. High-quality acrylic (like BCI Acrylic) is non-porous, resists fading, and wipes clean fast—great for busy households.

FAQ
Q: Can I keep a tub elsewhere and still convert here?
A: Definitely. Many homeowners keep one tub in a hall bath and convert the primary to a walk-in shower.
Q: Tile or grout-free walls?
A: Tile offers infinite design but needs grout care. Onyx or BCI Acrylic panels give you a stone look with quick cleaning—popular combo: tile accents + Onyx main walls.
Q: How fast can this be done?
A: After materials arrive, many conversions take about ~1–2 weeks onsite depending on glass, plumbing moves, and inspection timing.
