Entry width
An open shower needs enough opening to walk in comfortably without the panel crowding the path. The provider measures how the entry relates to the toilet, vanity and bathroom door.

Bathtub to Walk-In Shower Conversion in Miami
This project turns a bathtub alcove into an open shower you can step straight into, often with a fixed glass panel instead of a door. Getting that open feel depends on curb height, entry width and where the drain sits.
For homeowners planning a tub, shower or bathing-area project at a home they own in an eligible ZIP code. Not for mobile homes, billing or customer-service questions, or small accessory-only jobs.
In short
What bathtub-to-walk-in shower conversion involves
A bathtub-to-walk-in-shower conversion replaces a tub with a shower designed around easy, open entry. Instead of a framed door, it usually uses a fixed glass panel or a wide opening, and a very low curb or no curb at all. It solves a tub wall that feels like a hurdle and a space that feels closed in.
Options and layouts
Design choices for an open walk-in shower
Curbless entry
The shower floor meets the bathroom floor with no step, which takes careful floor preparation and slope. Whether it is possible depends on the subfloor and structure.
Low curb
A short curb helps hold water inside while keeping the step small. It is often more practical where the floor cannot be recessed.
Fixed glass panel
A single panel covers part of the opening and blocks most splash, leaving the rest open. Panel length and placement relate to the showerhead position.
Linear drain
A long, narrow drain placed along a wall or the entry, which can allow a single-direction floor slope. It often pairs with larger floor tiles.
Center drain
A traditional round or square drain with the floor sloping from all sides. It usually suits smaller tiles that follow the slope well.
Project fit
Who this project may suit
- Homeowners who want an open, uncluttered shower look
- Bathrooms with room for a wide, doorless entry
- People who find stepping over a tub wall tiresome
- Owners who dislike cleaning shower door tracks
- Projects aiming for a lighter, more spacious feel
Plan ahead
Planning and scope factors
Water containment
Without a door, spray direction, panel length and floor slope do most of the work. A shower that is too short for its opening may let water reach the bathroom floor.
Drain placement
Moving from a tub drain to a linear or center drain can mean relocating plumbing. On a slab, that may involve more floor work than a standard base.
Floor height and substrate
A curbless design may need the floor lowered or built up around the shower. The provider checks framing or slab conditions before recommending it.
Consultation
What a provider may discuss
- Width and depth of the existing tub alcove
- Whether a curbless or low-curb entry is realistic
- Showerhead and valve positions relative to the opening
- Glass panel size and how much opening to leave
- Drain type and the floor slope it would need
- Ventilation, since open showers share air with the room
What an open design can and cannot promise
A walk-in design can make entry easier, but it is not a safety or accessibility certification. Wet floors can still be slippery, and some splash beyond the opening is possible in smaller layouts. If accessibility standards matter for your household, any compliance question needs a project assessment.
Not every tub alcove is wide or deep enough for a doorless shower to stay comfortably dry. A standard enclosed shower may suit the space better, and the broader tub-to-shower conversion decision covers that path.
Process
A realistic project path
Share your goals
Explain why an open, walk-in style appeals to you and how the current tub limits you.
Measure and assess
A provider measures the alcove, checks the floor structure and notes drain and valve positions.
Choose entry and glass
Together you settle on curb height, panel size, drain type and finishes that fit the space.
Build the shower
The tub is removed, the floor is sloped and waterproofed, and walls, drain and glass are installed.
Final check
The provider runs water to show how the floor drains and how well the panel contains spray.
Miami considerations
Planning this project in a South Florida home
Many Miami homes sit on concrete slabs, which can make a curbless shower more involved than in homes with a raised wooden floor. Condo units add another layer, since recessing a floor or moving a drain may need association approval. The region's humidity also means an open shower benefits from a working exhaust fan to clear moisture from the room.

Related homeowner questions
There is no single number for every bathroom. The opening needs to feel comfortable to walk through, while the glass panel must still block spray from the showerhead. The provider weighs the alcove size, showerhead location and your preferences, then suggests a panel length and opening that balance access and dryness.
Sometimes. A curbless entry needs the shower floor to slope to the drain without a lip, which often means recessing the floor or raising the area around it. Slab homes and condo units can make that harder. A site visit shows whether curbless is practical or a low curb fits better.
Some splash is possible, especially in compact layouts. Careful showerhead placement, an adequately long glass panel and correct floor slope reduce it. Linear drains placed near the entry can also help. Ask the provider how the proposed design handles spray in your specific space.
No. A linear drain is one option that allows the floor to slope in a single direction and works well with large tiles. A center drain is a familiar alternative and suits many walk-in designs. The choice depends on the floor, the tile and where plumbing can reach.
Not necessarily, since many are built within the old tub footprint. A doorless design does work more comfortably with some extra depth or length, because that helps keep water inside. The provider can show whether your current alcove is enough or whether enlarging it is worth exploring.
Not exactly. A walk-in shower can reduce the step at entry, but an accessible remodel looks at the whole room, including clearances and support features. Any accessibility compliance question needs a project assessment. If the broader picture matters, ask about an accessible bathing area remodel.
