Meridian Quality Drywall is the bonus room and garage conversion drywall page for Meridian, Idaho. A room over the garage, an ADU-style conversion, or a shop turning into living space gets the rated board first, then a finish that matches the house.
Garage drywall is the Type X wall and ceiling that separate cars from people. This page is what happens when that volume becomes a room: 5/8-inch Type X still belongs on the garage ceiling, then soundproof details if you can hear the door, then knockdown or a skim so it does not look like a garage with paint.
What board goes in a Meridian bonus room?
- Garage ceiling / floor of the bonus room: 5/8-inch Type X, taped.
- Walls of the room: 1/2-inch regular unless the plan rates them.
- Bath in the conversion: moisture-resistant board, cement board in the shower.
- Ceiling of the room itself: 5/8-inch if joists are 24 inches on center.
Uninsulated garage walls in a Meridian winter will sweat if you hang regular board on cold concrete without a plan. Insulation and a moisture check come before the hang.
Garage conversion vs bonus room over garage
A bonus room over the garage is usually already framed in new south Meridian and Kuna plats. The drywall is a first hang plus punch. A conversion of an existing garage is a retrofit: existing Type X, new walls, often a slab edge that wants more than paint. Call with which one you have, ceiling height, and whether a bath is in the plan.

Common questions
Does a bonus room over a Meridian garage need Type X?
The ceiling of an attached garage that is also the floor of a bonus room is typically 5/8-inch Type X, joints taped, around every box. 1/2-inch regular board is the wrong product. The inspector is the last word on a given house.
Can you drywall a garage conversion into a room?
Yes, after the rated assemblies, insulation, and inspections the plan requires. Then the remaining walls get hung, taped, and finished to match the house: usually knockdown, sometimes a smoother living-room finish.
Should a bonus room be soundproofed?
If it sits over a garage or next to a living room, a second layer, offset seams, and acoustic sealant help. One layer of specialty board by itself is not an STC assembly. See soundproof drywall for the stack.
Is this the same as garage drywall?
No. Garage drywall is the fire-rated hang between cars and living space. Bonus-room and conversion drywall is making a habitable room: rated ceiling, often sound, and a finish people will live with.
