Preparing a Bathroom, Laundry Room or Garage for Cabinet Installation
Cabinets go in quickly compared with how long it takes to get the room ready for them. The walls, floor, plumbing and power decide whether a cabinet run sits square and stays dry, and those problems are far cheaper to find before the boxes arrive. A bathroom, a laundry room and a garage in Austin, TX each pose a different set of problems. This piece walks through what to check in each room, in the order a tradesperson would check it, with the local conditions that make Austin houses behave the way they do.
What should be checked in every room first?
Start with the floor. Lay a four foot level along the wall where the cabinets will stand and mark the high and low points. Houses on the clay east of the Balcones Fault shift with the seasons, and slab floors in Mueller, Hyde Park and Travis Heights often fall a half inch or more across a room. Cabinets can be shimmed to cover a slope, but the shim stack has to be planned, and the toe kick has to be cut to hide it.
Next, find the high point on the wall. A straight run of upper cabinets hung from the lowest point of the ceiling looks level, while the same run hung from the highest point leaves a gap above it that the crown molding has to bridge. Older homes in Clarksville and Tarrytown often have ceilings that drift by an inch over a long wall, so deciding where the crown will be scribed saves rework later.
Then locate the studs and mark them. Wall cabinets are heavy once loaded, and the screws that carry them have to land in framing. A plaster wall in an older house needs longer screws than a modern drywall wall, and a masonry wall needs anchors chosen for it.
How do the three rooms compare?
| Room | Main condition to settle | Typical problem found late | Material that tolerates it |
|---|---|---|---|
| Bathroom | Steam and splashes at floor and sink | A slow supply leak behind the old vanity | Plywood box, sealed edge banding, moisture-resistant panel in the base |
| Laundry room | Hookup positions, vent path and a floor drain or pan | A valve box that sits where a cabinet wants to go | Plywood box with a melamine interior and a sealed bottom |
| Garage | Heat in summer, ground moisture through the slab | A slab that is out of level or sweating at the edges | Plywood box raised off the floor, thick edge banding, heat-rated finish coat |
The table is a summary of the conversation that follows. Each room has a gating question that has to be answered before a single box is ordered.
What does a bathroom need before the vanity goes in?
Open the wall behind the old vanity if it is coming out, and look at the supply valves and the drain. A green crust on a valve or a dark stain on the subfloor means a slow weep, and the cabinet that goes in will fail from that spot unless the leak is fixed first. Replace old stop valves while the wall is open, since they cost little compared with a flooded base.
Check the floor under the old cabinet. Soft spots in the subfloor are common beside a tub or under a drain line. A vanity cabinet is only as good as what it stands on, and a spongy subfloor lets the box rock and the toe kick pull away from the floor. Patch the floor, then seal it, then set the cabinet.
Confirm the ventilation. A bathroom fan that vents into the attic rather than outside leaves moisture sitting over the room, and the vanity absorbs it over time. A fan that is rated for the room size and runs for twenty minutes after a shower does more for a cabinet than a better finish does.
Measure the plumbing cutouts against the drawer layout. A drawer box above a trap needs a cutout in the back or a U-shaped front, and those details have to be drawn before the cabinet is built. A shaker face on a vanity looks simple, but the drawer behind it is the part that takes careful planning.
What does a laundry room need?
Pull the machines out and measure everything behind them. The width of the washer and dryer is the easy number. The depth with the hoses and the vent attached is the number that decides how far forward a cabinet over the machines can sit. The dryer vent should run as straight as possible to the outside, and a crushed or kinked duct is a fire risk as well as a drying problem.
Look at where water would go if a hose failed. A drain pan under the washer with a line to a floor drain is ideal, and a pan without a drain still gives time to notice a leak. A laundry cabinet base next to the washer should have a sealed floor panel so a small leak damages a replaceable part and not the whole box.
Plan the shelf spacing around real objects. An adjustable shelf lets the cabinet follow the bottles and baskets that actually live there, and the pin holes should be drilled at even spacing so the shelf can move. A folding counter over the machines needs a gap at the back for the hoses and a support so it does not flex under a load of towels.
Decide whether the old cabinets in the laundry room are worth keeping. Where the boxes are sound and dry, refacing the doors can cost less effort than replacing the run, and refinishing the boxes brings the room up to date. Where a box has swollen from years of steam, replacement is the better call.
What does a garage need?
A garage in Austin needs a different set of questions. Heat climbs in an uninsulated garage through the summer afternoon, and ground moisture comes through the slab after a wet spring. Cabinets in that room should stand on legs or a raised toe kick so air moves under them, and the back should stand a little off the wall where afternoon sun heats the surface.
Check the slab for cracks and level before anything is set. Slabs on the clay soils east of the Balcones Fault move and crack, and a cabinet run on a cracked, sloping slab needs a leveling plan. Ground west of the fault is rocky and drains faster, which is why garages near Mount Bonnell and the Texas Hill Country edge tend to stay drier than those near the Colorado River.
Think about weight. A garage cabinet holds paint cans, power tools and chargers. Hardware has to be rated well above that load, and wall cabinets have to be fastened into studs with long screws. A hardwood or plywood shelf in birch outlasts melamine over a particleboard core, which bows after a summer under load.
Look at electrical and lighting before the cabinets block access. A run of garage cabinets over an outlet makes the outlet useless, so plan a switch and an outlet for the bench area while the wall is open.
How should deliveries and the install day be planned?
Clear the room completely. A crew that has to work around stored boxes loses an hour on every wall, and the cabinets themselves need a flat staging area. Store the boxes in the room where they will be installed for a day or two before work starts, so the wood and the finish adjust to the humidity there. Cabinets stored in an air-conditioned living room and then moved into a humid garage will move after they are hung.
Lay out the first cabinet from the corner or the tallest point, depending on the room. A run that starts from a straight reference stays straight, and a run that starts from the middle of a crooked wall carries the error to both ends. Check for plumb and level after each box and fasten them together before the run is fastened to the wall.
Leave the finish work for last. Crown molding, light rail, scribe strips and the cabinet pull hardware all go on after the boxes are fixed, because they cover small differences that the install exposes. A pull placed before the doors are aligned gets moved when the doors are adjusted.
What is the short version?
Check the floor, the wall and the water before the boxes arrive, and the install takes care of itself.
