Choose the base and surround before finalizing the door because curb geometry, drain position and finished walls determine the opening.
Last updated:
A reliable enclosure starts below the glass. The base controls slope, drainage and threshold geometry while the surround defines the finished width and mounting surface. Plan these components together so the door is measured from the real finished opening rather than a nominal framing dimension.

Frequently asked questions
When should final measurements be taken?
After the relevant finished surfaces and adjoining fixtures are in place.
Should components be chosen independently?
No. Confirm compatibility across the opening, mounting surface, clearances and water-control system.
When is professional confirmation worthwhile?
Use it for unusual geometry, concealed services, structural uncertainty or custom fabrication.
