Fit Storage Under the Sink Without Wasting Space

Custom bathroom vanities designed and built for homes in Scottsdale.

If your bathroom vanity has a cabinet door that swings into plumbing pipes or a drawer that stops short because of the sink drain, a custom vanity eliminates those clearance problems by designing storage around what is already in the wall. Knotty Customs LLC builds vanities in Scottsdale that fit your sink style, faucet spread, and plumbing configuration, so drawers extend fully and cabinet interiors are accessible without removing pipes or rerouting drains. Floating vanities mount to the wall and leave floor space open for cleaning, while freestanding units offer toe-kick storage or open shelving below.

Each vanity is built from moisture-resistant plywood and finished with paint or stain, then sealed with a water-resistant topcoat that holds up to splashing and humidity. Drawer boxes use dovetail joints and soft-close undermount slides, and doors are hung on European hinges that close quietly and adjust if the cabinet settles. Double-sink configurations include a center drawer bank or open shelf between the two bowls, and single-sink units maximize drawer depth for hair tools, cleaning supplies, or towels. Hardware finishes match your faucet and lighting fixtures, and countertops are templated after the vanity is installed to ensure the sink cutout aligns with plumbing.

If you are remodeling a bathroom in Scottsdale and want a vanity that fits your layout without wasting drawer space or blocking pipes, reach out to discuss dimensions and finish options.

What gets measured and how the vanity is built to fit

Knotty Customs LLC measures your bathroom on site in Scottsdale, noting the location of plumbing stub-outs, electrical outlets, light switches, and any walls or corners that limit vanity width. Sink style and faucet hole configuration are confirmed so the countertop can be drilled or cut accordingly. The vanity box is assembled in the shop using rabbet joints and wood glue, and interior panels are finished to resist moisture. Drawer interiors are sized to fit around P-traps and shut-off valves, and cabinet doors are built with concealed hinges that allow full access without removing plumbing.

Once installed, you will notice that drawers open completely instead of stopping halfway, and cabinet doors swing wide enough to reach cleaning supplies or toiletries stored in the back. If the vanity is wall-mounted, the floor underneath stays clear for mopping or running a robotic vacuum. Countertops overhang the front edge slightly to protect the cabinet face from water, and backsplashes are caulked to the wall to prevent moisture from seeping behind the vanity.

Installation includes anchoring the vanity to wall studs using lag bolts or French cleats, leveling the cabinet so the countertop sits flat, and connecting the sink drain and faucet supply lines. If the vanity is freestanding, adjustable feet are shimmed to accommodate an uneven floor. Countertops are installed after the vanity is secured, and the crew seals all joints with silicone caulk to prevent water damage. The vanity is ready to use as soon as the caulk cures, typically within 24 hours.

What homeowners want to confirm before starting the build

Most questions focus on whether the vanity can accommodate an existing sink, how much clearance is needed for plumbing, and what finishes hold up best in a bathroom with a shower or tub that generates steam.

Can the vanity be built to fit an existing sink?
Yes, as long as the sink dimensions and faucet hole spacing are provided before the countertop is cut. Undermount, vessel, and drop-in sinks all require different cutout styles, and the countertop is templated to match the sink you choose.
What finishes are best for bathroom humidity?
Painted finishes sealed with a waterborne polyurethane topcoat resist moisture better than oil-based stains, but stained vanities can also be protected with multiple coats of spar varnish or conversion varnish. Avoid flat or matte finishes in bathrooms with poor ventilation.
How much clearance is needed for plumbing inside the vanity?
Drawer boxes are notched or sized to clear P-traps and shut-off valves, and cabinet shelves are positioned above or beside plumbing lines. The crew measures plumbing locations during the site visit and designs storage around existing rough-ins.
Can a floating vanity support a stone countertop?
Yes, floating vanities are anchored into wall studs using steel brackets or a French cleat system rated to support the combined weight of the cabinet, countertop, and sink. The crew verifies stud locations and uses appropriate fasteners for your wall type.
What happens if the bathroom floor is not level?
Freestanding vanities are shimmed using adjustable feet, and floating vanities are leveled during installation by adjusting the mounting brackets. The countertop is templated after the vanity is set to ensure it sits flat against the wall and cabinet.
