Black Bathroom Board and Batten Wall Molding: wall elevation, color data (LRV 1.4), bathroom layout for 5, 7, 9 ft walls, cut list, calculator and pre-cut kit
Project calculator
Overview
Black is a very dark black with a neutral undertone and a calculated LRV of 1.4. Against white trim the contrast ratio is 14.84:1, which gives strong, graphic contrast; painted tone-on-tone, the board and batten pattern shows only through its shadow lines.
Board and Batten layout on a 7 ft bathroom wall
With battens every 16 in, a 7 ft wall takes 7 battens of 88 in plus a top rail: about 21.9 m of board including 10% waste. Use moisture-resistant polystyrene outside the shower spray zone and a bathroom-rated paint.
Building the board and batten pattern
Fix the top rail level first, then hang the battens from it at 16 in spacing. Start from the center of the wall so the end gaps match.
Painting molding in Black
Near-black walls turn molding into pure relief; use a satin or semi-gloss on the trim so the profile catches light.

How many battens for a 7 ft wall?
7 battens at 16 in spacing, plus a top rail across the 7 ft run.
Is Black warm or cool?
Black has a neutral undertone and reads as a very dark black. Its calculated LRV is 1.4, so it absorbs light, so tone-on-tone molding reads as deep relief.
Should trim be the same color as Black walls?
Painting the molding the same color gives a modern, tone-on-tone finish where only shadows show the pattern. White trim adds strong, graphic contrast (14.84:1), and black trim gives 1:1.
How high should the chair rail be in a bathroom?
About one third of the ceiling height: 32 in on an 8 ft ceiling, 36 in on 9 ft and 40 in on 10 ft. Use moisture-resistant polystyrene outside the shower spray zone and a bathroom-rated paint.
