How high should tile go on bathroom walls?

Tile height on bathroom walls depends on the area and your design goals, but there are practical minimums for water protection. In shower areas, tile should extend at least 6 feet high or to the ceiling, while around tubs you need a minimum of 6 inches above the tub rim, though 4-8 feet is more common.

For shower and tub areas, water protection is the priority. In shower stalls, most Ottawa contractors recommend tiling to the ceiling for the best water protection and easiest maintenance. If you stop short of the ceiling, 6 feet is the absolute minimum height, but you'll need to ensure proper waterproofing behind the tile and paint or finish the upper wall area with moisture-resistant materials. Around bathtubs, the Ontario Building Code requires water-resistant finishes, and tile should extend at least 6 inches above the tub rim, though 48-72 inches high creates better protection and visual appeal.

In non-shower areas like behind vanities or on accent walls, tile height is more flexible and design-driven. Popular options include wainscoting height (36-42 inches), half-wall height (48 inches), or full wall to ceiling for a luxury spa feel. Many Ottawa homeowners choose 48-60 inch height behind vanities, which protects against splashing while keeping costs reasonable.

Consider your ceiling height and room proportions when planning tile layout. In standard 8-foot ceiling bathrooms, stopping tile at 6-7 feet can make the ceiling feel low, while full-height tiling creates a more spacious feel. For basement bathrooms with lower ceilings, partial-height tiling often works better proportionally.

Proper waterproofing behind the tile is crucial regardless of height - this includes vapor barriers and waterproof membranes in wet areas. City of Ottawa requirements may vary for different installations, so confirm details with your licensed contractor who can ensure proper waterproofing and code compliance.
