Patented Interlocking Shower Bases





No more cutting or trimming pre-formed shower bases.

Our patented interlocking modular system replaces costly and labour intensive mortar beds. With our custom, pre-sloped high density shower bases, anything is possible!

The tile industry recommends waiting at least 3 days for mortar to properly cure in a setting bed. One of the benefits of White Matter® shower bases is the ability to install your waterproofing system immediately after placement of the base and curb.

All of our products are made from a high-density Expanded Polystyrene (EPS). White Matter® is completely customizable, lightweight, inert, durable, easy-to-install, and cost-effective, making it the perfect substrate for tile and stone.
