How we set 18x36
We plan every cut before the first tile goes up, set with large-format mortar and use a leveling system so adjacent edges stay flush.
Plan it before you decide
The Shower Builder lets you choose the tile size, the layout, the grout, the metal finish and the niche, and shows a 3D model as you go. Pine handles all pricing personally at the consultation — he’ll take great care of you.
18x36 questions
Do large tiles show less grout?
Yes. Fewer joints per square foot means less grout to see and to clean.
Is 18x36 hard to install?
It takes more prep than small tile. The wall has to be flat and the setting method has to match the size.
