Alabama-specific walk-in shower notes
A walk-in shower install in Alabama is a permitted project because drain and supply lines shift. Local pricing tracks national ranges - mid-range walk-in showers land $6,000–$15,000 installed, with frameless glass, custom tile, and steam-ready valves pushing higher. The below permit and licensing block are Alabama-specific.
- Licensing: Home Builders license required for any project over $10,000
- Permit authority: City or county building department
- Typical permit fees: $100–$400 for a bathroom remodel permit
Curbless vs. curbed
A curbed shower has a 3–5" threshold that keeps water in. It's the traditional approach: cheaper, easier to waterproof, and works with any subfloor.
A curbless shower has zero threshold - the shower floor is flush with the bathroom floor. It looks like a spa, it's future-proof for aging-in-place, and it requires a recessed subfloor (either poured shower pan lowered into the joists, or a linear drain sloped across the bathroom floor to a wall). Curbless costs $2,000–$5,000 more than curbed on a full remodel.
- Curbed: $3,000–$8,000 less than curbless, works on any floor
- Curbless: modern aesthetic, aging-in-place ready, requires recessed subfloor
- Half-curb (2") is a compromise, still requires stepping over, less flush look
| Curbed (3–5″) | Half-curb (2″) | Curbless | |
|---|---|---|---|
| Cost delta | Baseline | Small premium | +$2k–$5k |
| Aging-in-place | Poor | Improved | Best |
| Aesthetic | Traditional | Compromise | Modern / spa |
| Subfloor prep | Any floor | Any floor | Recessed pan or linear drain |
Shower pan types
Three main options. Each has different price, lifespan, and design flexibility.
Pre-formed foam pan (Kerdi, Wedi, Schluter): the modern standard. Foam panel with the slope built in, waterproof coating factory-applied. Install in a day, works with any tile.
Mortar-bed pan: old-school. Sand and cement sloped by hand, then waterproofed with a liner or membrane. Requires a skilled tile-setter. Cheapest but slowest and most prone to installation errors.
Acrylic or solid-surface base: pre-fab, drops in place. Comes in standard sizes only. Fastest and cheapest, limited to acrylic wall systems (won't tie into a tile shower).
- Pre-formed foam: $500–$1,200, 1-day install, most reliable
- Mortar bed: $300–$800 in materials, 2–3 days, dependent on skill
- Acrylic base: $200–$600, part of acrylic system
| Pre-formed foam | Mortar bed | Acrylic / solid-surface | |
|---|---|---|---|
| Material cost | $500–$1,200 | $300–$800 | $200–$600 |
| Install time | 1 day | 2–3 days | Hours |
| Reliability | Highest (factory slope) | Depends on installer | Highest for kits |
| Works with | Any tile | Any tile | Acrylic wall systems only |
Drains: center vs. linear
Center drains are the standard. They require the pan to slope in from all four sides, which limits tile size (large-format tile can't follow a compound slope). Cheapest and most familiar.
Linear drains sit on one edge (usually the wall opposite the shower entry). The whole pan slopes one direction. This lets you use large-format tile (24" x 48" and larger), gives a cleaner modern look, and is required for most curbless installations. Linear drains cost $200–$600 for the drain itself, plus $500–$1,500 more in labor.
- Center drain: cheapest, best for smaller tile, compound slope
- Linear drain: modern look, large-format tile, single slope, +$500–$1,500
Waterproofing: the part that matters most
Shower failures almost never come from bad tile. They come from bad waterproofing behind the tile. Once water gets past the membrane, it rots the substrate and shows up 3–5 years later as tile falling off or a soft spot in the shower floor.
Two main waterproofing systems. Sheet membrane (Kerdi, Wedi, Hydroban board): plastic sheets glued to the substrate, seams overlapped, corners sealed. Fastest and most reliable when installed correctly. Liquid membrane (RedGard, Hydro Ban liquid): brush or roll on, dry, second coat. Requires wet-film thickness gauge to verify coverage. Both work if installed to spec. Neither works if rushed.
- Sheet membrane: Kerdi, Wedi, Hydroban board - $2–$4/sq ft in material
- Liquid membrane: RedGard, Hydro Ban - $1–$2/sq ft in material
- Cement board alone is NOT waterproof (contrary to popular belief)
- Never skip corners, seams, and the pan-to-wall transition
Glass: framed, semi-frameless, frameless
Framed: aluminum frame around every edge. Cheapest, most durable, most dated aesthetic.
Semi-frameless: frame at the top and bottom, frameless door and side panel. Middle price, cleaner look.
Frameless: 3/8" or 1/2" tempered glass with minimal hardware. Highest cost, best aesthetic, weakest tolerance to construction errors (the shower opening must be square within 1/8").
Glass fabrication happens after tile install because the fabricator measures the finished opening. Add 5–15 business days for fabrication and installation.
- Framed: $600–$1,200 typical
- Semi-frameless: $1,200–$2,500 typical
- Frameless: $2,500–$5,000+ typical
- Shower door swing: pick outward-only or bi-directional
| Framed | Semi-frameless | Frameless | |
|---|---|---|---|
| Typical cost | $600–$1,200 | $1,200–$2,500 | $2,500–$5,000+ |
| Aesthetic | Dated | Cleaner | Best |
| Construction tolerance | Forgiving | Moderate | Opening must be square within 1/8″ |
| Fabrication lead time | 5–10 business days | 5–15 business days | 10–15 business days |

Frequently asked questions
What's the minimum size for a walk-in shower?+
Code minimum is typically 30" x 30" (varies by jurisdiction). Comfortable minimum is 36" x 48". For a curbless shower or an accessible shower, 60" x 36" is the smallest that works well.
How much does a walk-in shower cost?+
Acrylic walk-in shower installed: $9,000–$18,000. Custom tile walk-in shower: $14,000–$28,000+. Add $2,000–$5,000 for curbless. Add $2,500–$5,000 for frameless glass. Regional labor shifts these 15–30%.
Is a walk-in shower better than a tub?+
Depends on the household. Walk-in showers are safer, use less water, and look more modern. Tubs are better for young children and for resale in single-bathroom homes. Most master bath remodels remove the tub in favor of a larger shower.
How long does a walk-in shower last?+
Acrylic: 15–25 years before it looks dated or shows wear. Tile with proper waterproofing: 25+ years for the substrate; grout may need re-sealing every 2–3 years and re-grouting after 10–15 years.
Do I need a permit for this project in Alabama?+
Almost always yes if the project changes plumbing, electrical, or structural work - which most bathroom remodels do. Cosmetic-only work (paint, fixture swaps without changing supply/drain lines) generally does not. City or county building department.
How do I verify a bathroom remodeler's license in Alabama?+
Check with Alabama Home Builders Licensure Board. Home Builders license required for any project over $10,000. The absence of the required registration is disqualifying regardless of price or reviews.
What do bathroom remodel permits typically cost in Alabama?+
$100–$400 for a bathroom remodel permit. Fees vary by municipality and the scope of work triggering the permit.
