Questions & Answers

We’ll be installing extremely large format tile (23” x 59”) for a bathtub surround. There will be three full tiles beginning at the tub rim. Given the weight of these tiles, should the bottom one be installed first and allowed to set prior to installing the two above it? I’m thinking the weight of all three would produce a heavy load on the tub rim until the thin set is dry and spacers are removed. We set a large tile on a practice wall and had to wait an extended amount of time before pulling the spacers as the tile began to slid downward, i.e the weight concern. We’re using Schluter All Set over Kerdi Board with 1/2” trowel and back buttering.
