How Many Sq Ft of Tile for an Average Bathroom?

When remodeling or installing a new bathroom, tiling is one of the most significant factors to consider. Whether you’re tiling the floor, shower walls, or backsplash, knowing how many sq ft of tile for an average bathroom is essential for proper planning. The total square footage required for tiling depends on the size of the bathroom and which surfaces you plan to tile.

In this guide, we’ll explore how to measure and estimate the amount of tile you’ll need for an average bathroom, including some tips for avoiding common mistakes.

Measuring the Square Footage of an Average Bathroom

Before you can determine how much tile you need, the first step is to measure the square footage of your bathroom. The size of a typical bathroom varies, but most fall between 40 to 100 square feet. Here’s how to measure for both the floor and wall tiles:

Measuring the Bathroom Floor

To measure the square footage of your bathroom floor, follow these simple steps:

Measure the Length and Width: Using a tape measure, measure the length and width of the bathroom floor.
Multiply to Get Square Footage: Multiply the length by the width to get the total square footage. For example, if your bathroom floor is 8 feet long and 5 feet wide, the total square footage is 40 square feet.

Measuring the Shower Walls

If you’re planning to tile the shower walls, you’ll also need to calculate the square footage of each wall.

Measure the Height and Width of Each Wall: Measure the height and width of each shower wall you plan to tile.
Multiply to Get Wall Square Footage: Multiply the height by the width for each wall, then add them together to get the total square footage. For example, if one shower wall is 8 feet high and 4 feet wide, that wall is 32 square feet.

By adding the floor and wall measurements together, you can calculate the total square footage for the entire bathroom tiling project.

How Many Sq Ft of Tile for Different Parts of the Bathroom?

The amount of tile you need will vary depending on which areas of the bathroom you’re tiling. Here’s a breakdown of typical tile needs for various parts of the bathroom:

Bathroom Floor

For the average bathroom floor, which ranges from 35 to 100 square feet, you’ll need to purchase enough tile to cover that space, plus extra for waste and cuts. On average, it’s a good idea to buy 10% more tile than your calculated square footage to account for mistakes or broken tiles.

Small Bathroom: A small bathroom (5×8 feet) would require about 40 square feet of tile for the floor.
Medium Bathroom: A medium-sized bathroom (8×10 feet) would need approximately 80 square feet of tile for the floor.

Shower Walls

For shower walls, the amount of tile needed depends on the height of the walls and whether you’re tiling all sides or just a portion of the shower. A typical shower may require anywhere from 50 to 150 square feet of tile.

One Wall: If you’re tiling one wall of a shower that is 8 feet tall and 5 feet wide, you would need 40 square feet of tile.
Three Walls: For a standard three-wall shower stall with walls measuring 8 feet high and 4 feet wide, you’d need about 96 square feet of tile (32 square feet per wall).

Backsplash and Accent Areas

If you plan to add a backsplash behind the sink or other accent areas, the square footage will be much smaller. A backsplash typically requires around 5 to 15 square feet of tile, depending on its size.

How to Calculate Extra Tile for Cuts and Waste?

When calculating how many square feet of tile you’ll need for an average bathroom, it’s important to include a little extra for waste, cutting, and mistakes. Tile can break during installation, and you may need to cut pieces to fit edges, corners, or around fixtures.

Add 10% to 15% for Waste: To ensure you have enough tile for your project, it’s common to add 10% to 15% more than your calculated square footage. For example, if your total square footage is 100, plan to buy 110 to 115 square feet of tile.

Types of Tiles and Their Coverage

The size and type of tile you choose can also affect how much tile you’ll need for your bathroom. Larger tiles cover more area, but smaller tiles often require more cuts. Here are a few examples:

12×12-Inch Tiles: A standard 12×12-inch tile covers 1 square foot. For a bathroom requiring 50 square feet of tile, you’ll need 50 tiles, plus extra for waste.
Subway Tiles (3×6 Inches): Subway tiles are smaller and typically require more tiles to cover the same area. For example, it takes eight 3×6-inch tiles to cover 1 square foot.
Mosaic Tiles: Mosaic tiles, often used for shower floors or accent areas, come in small pieces mounted on mesh sheets. These typically measure 12×12 inches, covering 1 square foot per sheet.

Tips for Tiling an Average Bathroom

Here are a few tips to help ensure a successful tiling project:

Buy Extra Tile: Always purchase more tile than you think you’ll need to account for mistakes, waste, or future repairs. It’s better to have too much than to run out in the middle of the project.
Check for Consistent Tile Sizing: When buying multiple boxes of tile, make sure all tiles are from the same dye lot and size calibration to ensure consistent color and sizing.
Layout Before Installation: Before applying adhesive, lay out the tiles on the floor to ensure the pattern works and the cuts are minimal. This will also give you a better sense of how much tile you’re using.

Conclusion

Understanding how many sq ft of tile for an average bathroom is crucial to ensuring you have the right amount of material for your renovation or new installation. By measuring the floor, walls, and any additional areas like backsplashes, you can calculate the total square footage and plan accordingly.

Remember to factor in extra tile for cuts and waste, and always consider the type of tile you’re using for the best results. With the right planning and preparation, you can achieve a beautifully tiled bathroom that enhances both the aesthetics and functionality of your space.
