Short answer. Most small Los Angeles bathrooms can accommodate a walk-in shower with smart layout. Same-footprint tub-to-shower conversions run $8,000 to $18,000. Curbless designs with linear drains run $12,000 to $25,000. Full remodels that include the conversion run $32,000 to $55,000.
Walk-in showers replaced the tub in most LA bathroom remodels over the last decade. Younger buyers prefer them. Aging-in-place owners require them. The design challenge in a small bathroom is fitting a usable shower without making the room feel cramped. The five layouts below show the most effective configurations we have built.
Five layouts that work in small bathrooms
Layout 1: Same-footprint conversion (tub replaced with shower)
The tub niche is converted to a 32 by 60 inch walk-in shower. Existing drain location is reused. Lowest cost path. Works in any small bathroom with a standard 60-inch tub.
Layout 2: Corner shower
A 36 by 36 corner shower frees the rest of the bath for a larger vanity. Best for bathrooms under 40 square feet. Use a neo-angle glass enclosure to soften the corner visually.
Layout 3: Walk-through with no door
One fixed glass panel and an open entry, no swinging door. Requires careful slope and drain placement. Reads spa-like and adds 4 to 6 visual inches to the room.
Layout 4: Wet room
The entire bathroom is waterproofed and treated as a shower zone. Most flexible for unusual layouts. Higher waterproofing cost. Best for bathrooms under 35 square feet where any fixed shower would crowd the room.
Layout 5: Curbless shower with linear drain
No threshold, just one continuous floor at a slight slope toward a linear drain. The most modern and accessible option. Requires structural floor work to create the slope.
Material and finish choices
- Tile. Large-format porcelain (24 by 24 or larger) on the walls and a smaller mosaic on the shower floor for slip resistance.
- Glass. 3/8-inch tempered low-iron glass for frameless. 1/4-inch for framed.
- Shower valve. Single-handle pressure-balanced. Optional thermostatic for premium projects.
- Niche. 12 by 24 inch recessed niche at chest height for shampoo and soap.
- Bench. 18-inch deep floating bench on the long wall. Adds accessibility without crowding the room.
Common mistakes
- Choosing a curbless shower without verifying floor slope is structurally possible.
- Removing the only tub in a home with a single bathroom or no secondary tub.
- Using small mosaic tile on the floor with too much grout. Hard to keep clean over time.
- Forgetting to plan for shower steam control. Add an exhaust fan rated for the room volume.
