Can Warmup electric heating be installed in a shower?

When installing a Warmup heating system in a shower, it must be between two non-combustible materials.

Install the system on top of the sloped shower tray if the shower base is a poured mortar bed. Then cover with tile adhsive and tile over. Do not install Warmup directly over the rubber moisture membrane. We also advise against embedding Warmup in the mortar bed as long heating times could ensue.
