Attached Bathroom height 78” (6 1/2 ft) please suggest on which height can make tile border in whole bathroom ( tiles size 18” * 12”) tiles pic attached or any other suggestions (bathroom 77” * 93*)

Hello there, there's no specific height constraints to tiling when it comes to bathroom. It really depends on the layout and interior design of the bathroom. 5'-7' tiling height is more of a human scale as it stays at eye level. Anything beyond that would appreciable only from a certain distance. So, even if your bathroom is smaller/ narrower and more than 8' in height, tiling upto ceiling with an appropriate shade gives an illusion of space and a relaxing ambience. Hence, it is recommended to go till ceiling. Regards, Aurum Ideas and Spaces Bhubaneswar
