Standard Shower Dimensions
For this example, we'll use a common walk-in shower size:
Shower Walls: 88 sq.ft
Shower Pan: 15 sq.ft
Shower Curb: 5 linear ft
One Recessed Niche
Step 1: Calculate Wallboard Installation
Before any waterproofing or tile installation begins, the shower walls must be prepared with a proper tile substrate.
88 sq.ft × $3
= $264
Step 2: Calculate Floor Membrane Installation
A waterproof underlayment membrane helps protect the shower floor from moisture intrusion.
15 sq.ft × $3
= $45
Step 3: Calculate Shower Pan Preparation
Proper shower pan preparation creates the necessary slope toward the drain and ensures long-term performance.
15 sq.ft × $40
= $600
Step 4: Calculate Wall Tile Installation
For most porcelain tiles, including 12×24, 24×24, 24×48, and many small-format tiles, installation ranges from $14–16 per square foot.
Low-End Estimate
88 sq.ft × $14
= $1,232
High-End Estimate
88 sq.ft × $16
= $1,408
Step 5: Calculate Shower Floor Tile Installation
Most shower floors use mosaic tile because it follows the slope of the shower pan and provides better traction.
15 sq.ft × $17
= $255
Step 6: Calculate Curb Tile Installation
The shower curb requires detailed cutting, waterproofing, and finishing work.
5 linear ft × $40
= $200
Step 7: Calculate Niche Preparation and Tile Installation
A recessed niche adds convenient storage while creating a clean, built-in appearance.

Formula for Calculating Any Shower
You can estimate nearly any shower project using this formula:
Total Cost =
(Wall Area × $3)
(Floor Area × $3)
(Shower Pan Area × $40)
(Wall Tile Area × $14–16)
(Mosaic Floor Area × $17)
(Curb Length × $40)
(Niche Prep × $120)
(Niche Installation × $200–250)
What Can Increase the Cost?
Several factors can increase the final price of a shower tile installation:
Large-format porcelain panels
Natural stone tile
Multiple niches
Built-in benches
Curbless shower systems
Epoxy grout
Decorative borders
Herringbone or chevron patterns
Mitered 45-degree edges
Custom waterproofing requirements
These features require additional labor, specialized tools, and more precise installation techniques.
