Spray Foam Under Shower Pan
The best material to use under a shower pan is a fiberglass shower pan liner, which should be stapled over a concrete floor and between the wooden floor joists. According to Liquid Image Co., this liner creates a water-resistant barrier and helps protect the pan from water damage (2020). Sealing the liner with a waterproofing material can further extend the life of the shower pan.

If there are bigger gaps, thicker coats should be applied. It is important to note that spray foam should not be used on ceramic surfaces.
