Where Should a Shower Drain Be Placed?
Sep
A shower drain should be placed where the shower floor can slope effectively toward the drain while supporting proper drainage, waterproofing, and the desired tile layout. Traditional point drains are commonly positioned near the center of the shower, while linear drains may be installed along a wall, near the shower entrance, or in another location appropriate for the shower design.
The best shower drain placement depends on several factors, including the type of drain, shower dimensions, floor slope, tile size, waterproofing system, and whether the shower has a curb or curbless entrance.
Quick Answer: Center drains typically require the shower floor to slope toward the drain from multiple directions. Linear drains can provide more placement flexibility and, in appropriate shower designs, allow the floor to slope primarily in one direction.
Key Takeaway: There is no single best location for every shower drain. Center drains are commonly used with multidirectional floor slopes, while linear drains can be positioned along a back wall, side wall, or near the shower entrance in appropriate configurations. The final location should be coordinated with the shower’s floor slope, waterproofing system, tile layout, and drain specifications.
Does a Shower Drain Have to Be in the Center?
No. A shower drain does not have to be located in the center of the shower. While center placement is common with traditional round and square point drains, the best location depends on the drain type and overall shower design.
Center drains work well when the shower floor is designed to slope toward a single point from multiple directions. Linear drains offer additional placement options and may be installed along a back or side wall, near the shower entrance, or in another location supported by the drainage and waterproofing design.
When planning a new shower or remodel, drain placement should be considered before the floor slope, waterproofing, and tile layout are finalized.
Center Shower Drain Placement
A center shower drain is one of the most common configurations in residential showers. With this arrangement, the shower floor typically slopes toward a round or square point drain from multiple directions.
Center drains can be a practical option for smaller and traditionally configured showers. They also work particularly well with smaller-format floor tiles, which can accommodate changes in slope around the drain more easily than some large-format tiles.
Advantages of a Center Shower Drain
- Familiar and widely used shower configuration
- Compatible with many round and square drain styles
- Works with a variety of shower sizes
- Can provide balanced drainage when properly designed and installed
- Decorative drain covers can turn the center drain into an intentional design detail
Designer Drains offers decorative square shower drains and round shower drain covers in a variety of patterns and finishes.
Where Should a Linear Shower Drain Be Placed?
A linear shower drain can be placed in several locations, depending on the direction of the floor slope, shower entrance, waterproofing system, drain specifications, and overall bathroom design.
Three common locations are along the back wall, along a side wall, and near the shower entrance.
Along the Back Shower Wall
Installing a linear drain along the back wall can create a clean, streamlined appearance. In appropriate configurations, the shower floor can slope toward the drain in one primary direction rather than toward a central point from several directions.
This configuration can work particularly well in contemporary showers and bathrooms using large-format floor tile.
Along a Side Wall
Depending on the shower dimensions and plumbing configuration, a linear drain may also be positioned along a side wall.
As with a back-wall installation, the floor slope, waterproofing system, drain specifications, and tile layout should all be planned together.
Near the Shower Entrance
Linear drains may also be incorporated near the entrance of certain showers, including some curbless configurations.
Entrance placement requires particularly careful planning because the drainage system must work with the floor elevation, waterproofing, shower slope, and transition into the surrounding bathroom.
The location of a linear drain should be determined as part of the complete shower drainage and waterproofing design, rather than based on appearance alone.

Center vs. Linear Shower Drain Placement
Choosing between a center drain and a linear drain affects more than the appearance of the shower. Drain style can influence floor slope, tile layout, and the locations available for the drain.
| Consideration | Center / Point Drain | Linear Drain |
|---|---|---|
| Common Placement | Near the center or another designated point | Along a wall, edge, entrance, or other designed location |
| Floor Slope | Typically slopes toward one point from multiple directions | Can accommodate a primarily single-direction slope in appropriate designs |
| Common Shape | Round or square | Long rectangular channel |
| Tile Considerations | Smaller tiles can accommodate multidirectional slopes | Can work well with large-format tile layouts |
| Design Style | Traditional to contemporary | Contemporary and minimalist |
| Curbless Applications | Possible with appropriate design | Frequently incorporated into curbless shower designs |
Neither option is universally better. The right choice depends on the shower layout, tile, waterproofing system, desired appearance, and project requirements. Still deciding which to get? Read our blog on Center Drains vs. Linear Drains.
How Does Floor Slope Affect Shower Drain Placement?
Floor slope is one of the most important considerations when determining where a shower drain should be placed. The shower floor must direct water toward the drain rather than allowing it to collect elsewhere in the shower.
A traditional point drain generally requires the surrounding floor to slope toward one location from multiple directions. A linear drain can accommodate a more uniform slope toward the drain in certain configurations.
Because the required slope and installation details can vary by shower system and applicable plumbing requirements, drain placement, waterproofing, and floor construction should be coordinated before installation.
For additional technical guidance, review the International Plumbing Code requirements for shower floors and liners, which address waterproofing and slope toward the fixture drain.
How Does Tile Size Affect Shower Drain Placement?
Tile size can influence both the type and location of a shower drain.
Small-format tiles can more easily follow the multidirectional slopes commonly created around a traditional center drain. The additional grout joints allow the tiled surface to transition toward the drain.
Large-format tiles can be more challenging around multidirectional slopes because individual tiles may require additional cuts to conform to the shower floor.
For this reason, linear drains are frequently incorporated into showers using large-format tile. Certain linear-drain configurations can allow the shower floor to slope primarily in one direction, creating a cleaner tile layout with fewer complex cuts.
Where Should a Drain Be Placed in a Curbless Shower?
In a curbless shower, drain placement should be planned together with the shower’s floor elevation, slope, waterproofing, dimensions, and transition into the surrounding bathroom.
Linear drains are frequently incorporated into curbless shower designs because they can work with certain single-direction floor slopes and provide a streamlined appearance.
Depending on the shower design, potential locations may include:
- Along the back shower wall
- Along a side wall
- Near the shower entrance
- Another location specified by the drainage and waterproofing design
The primary goal is to create a shower configuration that directs water toward the drain while controlling water at the transition between the shower and bathroom.
For accessible shower projects, accessibility depends on the complete shower configuration, not simply the type or location of the drain. You can learn more in Designer Drains’ ADA-compliant drain options and accessible shower guide.
Should Shower Drain Placement Be Planned Before Tiling?
Yes. Shower drain placement should be determined before the shower floor is tiled.
The location of the drain can affect:
- Floor slope
- Waterproofing
- Tile cuts and grout lines
- Drain-body installation
- Finished floor elevation
- Drain-cover size and shape
- Overall shower appearance
Planning the drain location early also allows homeowners and designers to coordinate the visible drain cover with the shower tile, faucets, hardware, and other bathroom finishes.
If you’re replacing a drain cover while keeping an existing drain body, use the Designer Drains Drain Compatibility Chart to help identify compatible replacement options.
How to Choose the Best Shower Drain Location
Before deciding where to place a shower drain, consider these seven factors:
1. Drain Type
Determine whether the shower will use a round, square, linear, or another appropriate drain configuration.
2. Shower Size and Layout
The dimensions and configuration of the shower affect where water needs to travel and how the shower floor can be constructed.
3. Floor Slope
Drain location and floor slope must work together to direct water toward the drain.
4. Tile Size and Pattern
Consider how drain placement will affect tile cuts, grout lines, pattern alignment, and the overall appearance of the shower floor.
5. Waterproofing System
The drain must be compatible with the selected waterproofing and drainage system, and the manufacturer’s installation requirements should be followed.
6. Curbless or Accessible Design
Curbless and accessible showers require careful coordination of floor elevations, drainage, waterproofing, transitions, and applicable accessibility requirements.
7. Aesthetics
The drain is one of the visible details of a finished shower. Its shape, pattern, size, and finish can be coordinated with tile, faucets, shower hardware, and other bathroom finishes.
