We want a beaded board wainscoting in a small bath that includes a tub surround (no shower). We have ruled out solid surface simply because the walls in TOH are not plumb. We found Crossville tile that measures 12x24 but the wainscoting is 48 inches high. Is there a taller tile available or how would we stagger the 24 inch tiles to make it look like solid beaded board? Or, is there a better alternative that we have not considered? We love the look of beaded board however, our primary concern is avoiding water penetration and mold. Your advice would be appreciated.
