Kitchen — the room that earns its keep.

Every guide we've ever written for the busiest room in the house — sorted by what you came here to do. 312 kitchen projects across repair, install, build, clean, organize, and decorate. Kitchen is one of ten room hubs on HowTo: Home Edition. It's the room where the most expensive appliances live, the most square footage of countertop is most exposed to wear, and the most labor-saving installs (under-cabinet lighting, soft-close drawer hardware, a faucet with a real pull-down sprayer) make the biggest daily difference.

How to use this hub

Pick a verb at the top — what are you trying to do? — and the hub narrows to the relevant slice of guides. If you don't know what you need yet, scroll down for the most-searched kitchen projects across all six task lanes, plus a six-mistake list that covers the things every kitchen DIYer learns the hard way at least once.

Kitchen by task lane — six paths into the kitchen

Repair the kitchen — 64 guides

Fix the leak under the sink, the burner that won't light, the disposal that hums but won't spin, the dishwasher that drains slowly. Repair is the biggest kitchen lane because the kitchen has the most moving parts in the house — water in, water out, electricity, gas, refrigeration, ventilation. Browse all kitchen repair guides →

Install in the kitchen — 78 guides

Backsplashes, faucets, under-cabinet lighting, range hoods, dishwashers, garbage disposals, pendant lights, soft-close hardware, and 70 more kitchen installations. Install is the highest-ROI kitchen lane — every install is a visible upgrade or a daily-use improvement. Browse all kitchen install guides →

Build for the kitchen — 41 guides

Open shelves, a butcher block island, the breakfast nook bench, a coffee bar, a custom drawer organizer. Build is the kitchen lane for the projects you can't buy off the shelf — the things that fit your specific kitchen because you measured your specific kitchen. Browse all kitchen build guides →

Clean the kitchen — 56 guides

Burnt-on grease, mineral spots on the faucet, the inside of an oven, the gasket on the dishwasher, the filter on the range hood. Cleaning is the kitchen lane that pays back daily — every minute saved on cleanup compounds across the year. Browse all kitchen cleaning guides →

Organize the kitchen — 38 guides

Pantry overhauls, drawer dividers, under-sink storage systems, spice-rack rebuilds, junk-drawer fixes. Organize is the kitchen lane where the cheapest changes (a $15 set of drawer dividers) deliver the most disproportionate quality-of-life gains. Browse all kitchen organize guides →

Decorate the kitchen — 35 guides

Paint colors that survive grease and steam, cabinet hardware swaps, open-shelf styling, art that earns its place. Decorate is the kitchen lane for the cosmetic moves that can't be undone with a wipe — the paint and pattern decisions that change the room's mood. Browse all kitchen decorate guides →

The five most-searched kitchen guides

Across all six task lanes, these are the projects readers come to the site for most often. If you're not sure where to start in your kitchen, start here.

• How to tile a kitchen backsplash. The single highest-ROI kitchen install. One weekend, $180–$420, intermediate.
• How to install a kitchen faucet. A like-for-like swap in 60-90 minutes. Right first plumbing install for any homeowner.
• How to fix a leaky faucet. Two cartridge types, three minutes of disassembly, $8 in parts.
• How to deep clean an oven. The 4-hour overnight method that doesn't use the self-clean cycle (which warps oven sensors and burns out heating elements).
• How to paint kitchen cabinets. Two weekends, ~$180 in materials. The whole-kitchen transformation that doesn't require a contractor.

Six mistakes every kitchen DIYer makes once

We've made every one of these. Some twice. The ones that cost the most are the ones that touch water — kitchens are the room with the highest-stakes intersection of water, electricity, and finished surfaces.

1. Not shutting off the water before working on the faucet

The valves under the sink are usually older than the faucet you're replacing. They look like they work. The first time you put pressure on one to actually shut off the water, half of them fail. Test the shutoff valves a week before the install. Replace the ones that don't fully close (about $12 each) so you're not doing emergency plumbing during a sink swap.

2. Tightening plumbing fittings with channel-locks

Plumbing fittings are designed to be hand-tightened plus 1/4 turn with a wrench, not torqued. A channel-lock crank cracks plastic threads, distorts metal fittings, and creates leaks where there weren't any. The fix: hand-tight first, then 1/4 turn with a wrench, then leak-test. Tighten more only if it actually leaks.

3. Ignoring outlet height when planning a backsplash

Standard outlets sit 48 inches from the floor. New 4×12 stacked tile sometimes lands an outlet exactly between two tile rows. Plan the layout so outlets land mid-tile, not on grout lines, before you spread thinset. The backsplash guide covers this in Step 5.

4. Painting cabinets without removing the doors

It seems faster. It's not. Doors painted in place show drips on the front face, leave brush marks at the perimeters, and lock into the frame as the paint cures. Remove every door, lay them flat on sawhorses, paint front and back separately, then rehang. Adds 30 minutes to the project; saves a weekend of rework.

5. Buying drawer organizers before measuring the drawer interior

Drawer organizers are sized to standard interior dimensions that very few drawers actually have. Measure the inside width, depth, and height of the drawer with a tape — not the outside, not the cabinet opening. Then buy. Adjustable bamboo organizers solve about 80% of the mismatch problems.

6. Replacing the disposal without checking the drain alignment

Garbage disposals come in different heights. A new disposal often sits 1-2 inches lower or higher than the old one, which means the drain trap no longer aligns with the wall stub-out. Measure the old disposal height before buying the new one. If the heights don't match, you're also replacing the trap — add 30 minutes and $15 to the project.

The kitchen — what's worth paying a pro for

Most kitchen DIY is within range. A few categories aren't.

• Gas appliance hookup. Connecting a gas range or cooktop is licensed plumber work in most jurisdictions. The penalty for a slow gas leak is fire or carbon monoxide. Always pay for the install if the appliance is gas.
• New circuits or panel work. Adding a 240V circuit for an induction range, or a dedicated 20A circuit for a microwave, requires a licensed electrician and a permit in most cities.
• Anything inside the wall. Re-routing supply lines, moving drain stacks, adding a vent — pro work. The risk of an in-wall leak you don't see for six months is too high.
• Custom cabinetry. Face-frame box construction is intermediate-DIY; full-overlay cabinets with concealed hinges and integrated lighting are pro work.
• Tile floor over a slab with a slope. Backsplash tile is forgiving; floor tile over a sloping substrate requires self-leveling underlayment, which is its own skill curve. Pay the tile-setter.

The kitchen by zone — a different way to think about the room

A useful frame from professional kitchen designers: the kitchen breaks into four work zones, and most successful kitchen projects make at least one zone better.

The wet zone — sink, dishwasher, water filtration

Everything related to water. The wet zone is where most plumbing repairs and installs happen. It's also where most kitchen leaks start — the supply line, the drain trap, the dishwasher hose, the icemaker line behind the fridge.

The hot zone — range, oven, microwave, range hood

Everything related to heat. Range, cooktop, wall oven, microwave, range hood, toaster oven. Hot zone projects intersect with electrical (240V circuits, microwave dedicated circuits) and ventilation (range hood ducting). Higher stakes than the wet zone — fire risk requires more conservative DIY scope.

The cold zone — refrigerator, freezer, beverage cooler

Refrigeration. Mostly install work (water lines for icemakers, leveling, ventilation clearance) since the cold-zone appliances themselves rarely need user-serviceable repair. The right time to install a water filter for the icemaker is during refrigerator placement.

The prep zone — counters, island, pantry, knife storage

The work surface. Counter, island, cutting board storage, knife block or magnetic strip, the trash pull-out, the spice rack. Prep zone projects are usually organize and decorate work — drawer dividers, knife strips, cutting board racks.

Five tools that earn their place specifically in kitchen work

Beyond the general home-install kit, these five tools come up repeatedly across kitchen projects.

• Basin wrench ($18). The under-sink faucet wrench. The single most-essential kitchen-specific tool — without one, faucet replacement is a knuckle-bleeding disaster.
• Magnetic stud finder plus electronic stud-and-cavity scanner ($60 combined). The kitchen has more in-wall water lines and electrical than any other room. The cavity scanner catches what the stud finder misses.
• GFCI outlet tester ($12). Confirms a GFCI is wired correctly and the trip works as designed. Plug into every countertop outlet after any kitchen electrical install.
• Notched trowel, 3/16-inch V-notch ($14). For backsplash work and any wall tile project. The notch size matches the tile thickness.
• Refrigerator coil brush ($12). The single tool that extends fridge lifespan. Vacuum the coils every 6 months — most fridge failures are heat-management failures from clogged coils.

Refresh, renovate, or rebuild — three scopes

Most kitchen projects fall into one of three scopes. Knowing which scope you're in saves money, time, and contractor calls.

Refresh — under $1,000, weekends only, no permit

Paint cabinets. Replace hardware. New backsplash. New faucet. New under-cabinet lighting. Refreshes change how a kitchen looks and feels without touching the cabinets, counters, or layout. Almost entirely DIY — every project on this scale appears in our six task lanes with step-by-step guides. Best ROI per dollar of any kitchen work.

Renovate — $5,000–$30,000, weeks to months, sometimes a permit

New counters. New appliances. Possibly new cabinet doors over existing boxes. Sometimes a structural change like opening a wall to a dining room. Renovations require coordinating multiple trades (countertop fabricator, electrician for new outlets, plumber for new fixtures). DIY scope is ~30% of the work — the demolition, the cabinet hardware swaps, the painting. Pros do the rest.

Rebuild — $30,000+, months to a year, definitely a permit

Down to studs. New cabinets, new appliances, new layout, new electrical, new plumbing, new flooring, often new windows. Rebuilds are full general-contracting projects — the GC fee alone is 15–20% of the budget. DIY scope is approximately zero except for the design decisions and the daily monitoring of the contractor's work. Read our General Contracting trade page if you're considering this scope.

The shape of a successful kitchen project: pick a scope, stay in it. Refresh-creep into renovation is how most kitchen budgets blow up — "while we're at it, let's do the counters" turns a $1,500 weekend into a $15,000 month.

The five-minute kitchen audit — what to fix this weekend

Walk through the kitchen with a notebook. Spend exactly five minutes. Note every small thing that doesn't work the way it should. The list almost always falls into the same five categories — and each one has a Saturday-afternoon fix.

• The drawer that doesn't close all the way. Usually a dropped slide rail or a bent stop. Fix: realign the slides ($0, 15 minutes) or replace the slides with full-extension soft-close ($25 per drawer, 30 minutes).
• The cabinet door that hangs crooked. Almost always the hinge adjustment screws have backed out. Fix: 5 seconds with a Phillips screwdriver. The center screw on a Euro-style hinge controls vertical, the outer screw controls horizontal, the depth screw controls how flush the door sits.
• The faucet sprayer that doesn't retract or sprays sideways. The aerator is clogged with mineral buildup. Fix: unscrew the aerator (or pull-down spray head), soak in white vinegar overnight, rinse and reinstall. $0, 5 minutes of work.
• The light over the sink that's noticeably dimmer than the others. Bulb is wearing out — even LEDs degrade. Fix: replace with a matching color temperature (most kitchens want 3000K or 2700K — colder light reads "office," warmer reads "home").
• The drawer organizer that no longer matches what's in the drawer. The most common kitchen pain. Fix: dump the drawer, sort what you actually use vs what you haven't touched in a year, buy a new bamboo organizer sized to what stays. Adjustable bamboo with movable dividers solves this for under $25.

The kitchen and the rest of the home

Most kitchen projects don't stop at the kitchen. The under-cabinet lighting install reminds you that the dining room could use better light too. The new faucet under the sink reminds you the bathroom faucet is starting to drip. The backsplash project ends with you realizing the wall paint in the adjacent room is a different white than the one you just chose. Three connections worth knowing about:

• Kitchen-to-dining-room transitions. Open floor plans put the kitchen and dining room in visual conversation. Kitchen paint, kitchen lighting, kitchen flooring all visually extend across the threshold. Plan kitchen projects with the dining room in mind, especially if there's no door between them.
• Kitchen-to-laundry overlap. In many homes the laundry room shares a wall (and sometimes a circuit, sometimes plumbing) with the kitchen. A kitchen renovation that touches plumbing or electrical often affects laundry too. Worth checking before you swing a hammer.
• Kitchen-to-basement transitions. The kitchen sits over the basement in most homes. Plumbing leaks and dishwasher floods always end up in the basement ceiling. The smart leak detector you put under the sink is also basement insurance.

About this hub

The kitchen room hub aggregates every guide we've written for the kitchen across all six task lanes. Each lane × kitchen intersection (Install × Kitchen, Repair × Kitchen, etc.) has its own dedicated landing page with the full menu of guides at that intersection — for example, Kitchen × Install has all 78 install guides in one place. The room hub is the right starting point if you don't know what you want to do; the lane × room intersection is the right starting point if you do.

One last thing — the kitchen-project rule we live by

If a kitchen project takes a weekend or less, do it yourself. If it takes a week, get one quote from a pro and one from yourself (in honest hours). If it takes a month, hire it out unless you've done one before — kitchens have too many compounding finish-grade decisions for a first-timer to manage solo across that timeline. The trades and the room sit in productive tension: the kitchen wants finished work; the trades want fair scope. The right project for DIY in the kitchen is one where you can finish what you start before the dishes pile up. Anything bigger, call.
