We would like to install this on the bathroom/shower floors in our cabin. It can be very damp because it's a small area. Would the 2.5 in tiles allow for proper drainage and can these be cut to size?

Our Jamboree Playground Tiles are porous and allow water to flow through the tiles. So they will drain properly in your shower. We also do offer a wide range of shower tiles that you may be interested in on our drainage tiles page. Our Jamboree tiles can be cut to fit with the use of a large bread knife or band saw.
