How to Install Beadboard in a Bathroom

Beadboard transforms a bathroom from ordinary to cottage-like in a single weekend. Those narrow vertical planks with routed grooves catch light differently than flat drywall, add texture, and hide small imperfections while resisting moisture better than paint alone. The work itself is forgiving—cutting is straightforward, fastening is simple, and mistakes are easy to hide behind trim. What matters is patience at the start: get that first panel truly vertical, and the rest follows naturally. You're not building cabinetry or doing finish carpentry; you're installing a wall system that looks intentional and feels like it's been there for years.

1. Measure the room and plan panel layout. Measure the height of your walls from floor to ceiling at several points. Beadboard typically comes in 4-foot sheets, so decide whether you'll run it full height or as wainscoting (usually 36 to 48 inches up). Mark a level line around the room where the top of the beadboard will sit. Plan your layout so you're not ending with a narrow sliver of panel on corners—adjust the width of your first panel if needed so the last panel is a reasonable width.
2. Prep the wall surface. Fill any significant dips in the drywall with joint compound and sand smooth once dry. Wash the wall with a damp cloth to remove dust and mildew. Prime any patched areas and any dark stains with primer-sealer so they don't bleed through later. You don't need to remove existing paint, but glossy surfaces should be lightly sanded to give the adhesive something to grip.
3. Mark your first panel line and install starter strips. Find the most visible corner of the room—typically where your eye lands first when entering. Using a level, draw a perfectly plumb line on the wall where your first panel's inside edge will sit. If running full height, snap a level chalk line at the top as a visual guide. If installing wainscoting, nail a horizontal 1x2 backer strip at the marked height to anchor the top of the panels; this gives the adhesive something to push into and keeps panels from sagging.
4. Apply adhesive and install the first panel. Cut your first panel to length (trim the top and bottom square with a miter saw or table saw). Apply a bead of panel adhesive along the studs or every 16 inches across the wall, following the adhesive manufacturer's instructions. Position the panel against your plumb line, press it firmly into the adhesive, and fasten with finish nails every 16 inches along the edges and down the middle if the panel is wider than 6 inches. Check for plumb every few fasteners; small adjustments now prevent problems compounding across the room.
5. Install remaining panels with staggered joints. Apply adhesive to the wall, position the next panel with its groove-side edge fitting against the previous panel's bead (or floating slightly apart if you prefer a shadow line), and fasten. Work your way around the room, checking every third panel for plumb. Stagger the top and bottom seams so they don't align vertically every few rows—it looks better and creates less stress concentration. Panels should fit snugly but not so tight that they're forced; wood expands and contracts with humidity.
6. Cut and fit around fixtures and obstacles. For soap niches, mirrors, or outlet boxes, measure carefully and cut openings with a jigsaw or oscillating multi-tool. Dry-fit first, then apply adhesive and fasten. For pipes and corners, you can wrap beadboard around them with miter cuts, or leave a small gap and cover it with quarter-round trim. Corners are easiest to finish with matching inside and outside corner trim pieces rather than trying to cut tight miter joints.
7. Install trim and caulk joints. Once all panels are up and the adhesive has set overnight, install trim at the top edge (typically a 1x2 or molded chair rail), at the bottom (baseboard or cap trim), and at inside and outside corners. Caulk the seams between panels with paintable silicone caulk, smoothing with a wet finger. This seals the gaps, prevents water from migrating behind the panels, and creates the finished look. Let caulk cure fully before painting.
8. Prime, paint, and seal. Prime all beadboard, caulk, and trim with a bathroom-rated primer that resists mildew. Once dry, apply two coats of semi-gloss or satin bathroom paint. Semi-gloss is more moisture-resistant and easier to wipe clean; satin is more forgiving of imperfections. Let the final coat cure for a week before running the shower; moisture from steam will penetrate unsealed paint and can cause swelling.
