Absolutely. All of our tiles are rated for all residential floor and wall applications, as well as some light commercial, so they are extremely durable. The only consideration would be the dimensionality of the goldfish, which has a slightly raised ridge down it's back that protrudes about 1/4" above the body. If you plan the layout so that the flatter field and water lilies are in the center of the shower and the goldfish and koi are closer to the perimeter, it might be a bit more comfortable for your bare feet. We do full custom layouts, so we can create a design that fits your space and ships mesh mounted for easy installation. Feel free to call or e-mail with any further questions or for a local distributor in your area. Visit our website, www.wetdogtile.com for additional info. Thank you for your inquiry!
