Yes, benches and seats and other creative shower options can be built using 2” thick ProTile™ building panels without the need for a wooden or metal framework. ProTile™ building panels can be cut and fitted together using ProTile™ joint sealant. When a foam edge without a factory applied finish remains visible before setting tile, simply smooth thinset with the flat side of your trowel on to the unfinished foam edge, followed by standard tile installation methods.
