THE SHORT ANSWER
Estimate shower door installation after identifying the opening, door configuration and condition of the mounting surfaces. Separate product selection from installation and make tile repair an explicit decision.
The worked project in this guide is one framed shower door replacement. It uses an original fictional job to explain the estimating decisions, with a matching shower door installation PDF example. Replace the example inputs with your measurements, supplier quotes and labor costs.
1. Measure the finished opening
Record width and height at the positions required for the selected product, plus swing clearance. A nominal shower size does not establish the actual door size.
2. Inspect mounting surfaces
The example assumes sound, suitable enclosure surfaces. Loose tile or hidden deterioration can change the mounting approach and must be resolved before the base scope is treated as complete.
3. Specify the selected assembly
Framed, semi-frameless and other products have different components. Replace the product allowance with the selected unit and supplier information before ordering.
4. Define water and finish expectations
Describe sealant, door adjustment and a basic operation check. State whether removal damage, grout touch-up or adjacent tile repair is included.
A worked shower door installation calculation
One illustrative door allowance × $680 = $680, and one installation line × $375 = $375. Together they are $1,055; measurement, removal, hardware and cleanup remain separate.
The complete example contains 7 lines totaling $1,580.00 before any tax or markup. These are deliberately stated example prices, not a survey, regional price recommendation or offer to perform the job.
To set your own selling price, review direct costs and decide how you will cover overhead and profit. For example, adding 20% to a $1,000 cost gives $1,200; it does not produce a 20% gross margin. Use the approach you intend consistently, and avoid adding a second markup to rates that already include it.
Before you send the estimate
- Measure the finished opening and swing clearance.
- Confirm the exact door product.
- Inspect mounting surfaces.
- State tile repair and disposal boundaries.
Example scope boundary: No tile replacement, enclosure rebuild, plumbing work, concealed damage repair or new shower-pan work.
Review the client name, location, validity date and all calculations. Tax is not included in this example; determine the correct treatment for the actual work rather than copying a sample percentage.
Common questions
Why is an opening measurement line useful?
It makes the product-ordering basis visible and allows an estimate to distinguish a measured replacement from a guessed nominal size.
Does installation include tile repair?
Only when listed. Existing tile condition should be inspected and any repair agreed separately.
