Pony Wall in Shower in Construction
In modern bathroom design, functionality and aesthetics go hand in hand. One structural feature that embodies both is the pony wall in a shower. Whether you’re working on a full remodel or new construction, adding a pony wall can transform your shower space, offering privacy, design flair, and structural support—all without sacrificing openness.
This article explores the purpose, construction methods, benefits, and best practices of using pony walls in showers within the context of construction.
🧱 What Is a Pony Wall in Shower Construction?
A pony wall—also known as a half wall or knee wall in some regions—is a short wall that doesn’t extend all the way to the ceiling. In shower construction, a pony wall is typically built along the shower perimeter to:
- Create a partial enclosure
- Provide privacy without full isolation
- Serve as a support structure for glass panels
- Conceal plumbing, niches, or built-in shelving
The wall is generally between 30 and 48 inches high and may be finished with tile, stone, glass, or waterproof surface materials.

🛠️ How to Build a Pony Wall in a Shower
Step 1: Plan the Layout
- Mark the pony wall location and size.
- Identify plumbing requirements (if applicable).
Step 2: Frame the Wall
- Use pressure-treated bottom and top plates.
- Frame vertical studs 16″ on center.
- Add horizontal blocking for glass or fixtures.
Step 3: Anchor the Wall
- Anchor bottom plate into the floor with Tapcon screws or anchors.
- Ensure framing is plumb and level.
Step 4: Sheath with Cement Board
- Use screws to attach cement board.
- Leave 1/8″ gaps between boards and seams for waterproofing.
Step 5: Waterproof Thoroughly
- Apply liquid waterproof membrane over the entire wall, corners, and seams.
- For extra protection, use a sheet membrane over the wall and adjoining areas.
Step 6: Tile and Finish
- Apply thin-set mortar and tile or install stone.
- Use a solid-surface or sloped tile cap to prevent water pooling.
💡 Design Tips for Shower Pony Walls
- Add niches into the pony wall for soap and shampoo storage.
- Slope the top cap slightly towards the shower for drainage.
- Match tile with the rest of the bathroom or use a contrasting material for visual interest.
- Use frameless glass panels above the pony wall to maintain openness while containing water.

The terms are sometimes used interchangeably, but generally, a pony wall refers to a half-height room divider, while a knee wall supports structural elements like rafters.
Q4. What materials should be used for a pony wall in a bathroom?
Use pressure-treated lumber, cement board, tile, and waterproof membranes for durability and moisture protection.
Q5. Can a pony wall support glass panels?
Yes. Pony walls are often designed to support frameless or semi-frameless glass panels. Reinforcement inside the wall is essential.
Q6. Do I need to waterproof the pony wall?

Yes. Many pony walls include built-in niches for soap, shampoo, and other shower accessories. Proper waterproofing is essential around these openings.
