Two simple 1x8 towers bridge a top board over a bathroom vanity, hiding recessed light wiring inside — sized entirely around YOUR vanity, ceiling height, and light placement, not a fixed dimension.

Build two towers from the 1x8 boards using 1-1/4" finish nails and glue. Adjust your tower height and width to your own bathroom BEFORE cutting — the right size depends on where your vanity light sits, how much clearance you have above the vanity, and how wide your vanity and sink are.

Once the two towers are built, nail the light board on top, connecting them — sized to your vanity's actual width (48" for a standard vanity). This board is what the recessed lights mount into.
Materials: Recessed cabinet lights
Install the recessed lights into the light board and connect all the wiring while the assembly is still on the ground — this is much easier and safer than doing it overhead once the hutch is mounted. Once it's in place, all that's left is connecting to the existing vanity light box.
This is household electrical wiring — follow your local code, and bring in a licensed electrician for this step if you're not confident with it.
Tools: Drill / Driver
Move the built and wired hutch into place over the vanity. If the towers land on wall studs, secure them there directly. If they don't — which is common, since tower spacing rarely lines up with stud spacing — the hutch can rest on the vanity top and be held in place by the base moulding added in a later step; this has held up for years in real use.
Nail through the bottom board to attach, leaving enough clearance from the ceiling to maneuver the box into place without damaging it.
Tools: Brad Nailer, Circular Saw. Materials: 1x3, 6 ft, Finish nails, 1-1/4"
If your vanity sits in a corner, cut and add the corner trim piece and the longer front-trim length (49-1/2" instead of 48-3/4") to account for the wall relationship — skip this step entirely for a standard, non-corner install.
Tools: Brad Nailer. Materials: Base moulding, 4-1/4", 6 ft, Finish nails, 1-1/4"
Cut and attach the base moulding around the bottom of the hutch, using shorter nails than you used for the case itself — base moulding usually runs under 3/4" thick. This adds a finished detail and meaningfully strengthens the bottom joint, especially if the towers aren't anchored to studs.
Tools: Brad Nailer. Materials: Crown moulding, cut to fit the room
Run crown moulding around the entire room, including across the top of the vanity hutch, to finish out the top joint and tie the piece visually into the room.
