Should You Remodel the Kitchen or the Bathroom First?

If the house has one full bathroom and something in it is failing, remodel the bathroom first, because a failing bathroom has no workaround. With two full baths, the kitchen usually goes first, since a kitchen can be revisited in pieces later and a tile shower cannot. Remodel Now remodels kitchens and bathrooms across Baltimore County.

The question underneath the question

Most people asking this already know both rooms need work. What they are really asking is which one they can live with for another year.

That reframes the answer. Three things decide the order, and none is taste. How many full bathrooms the house has. Which room is failing rather than merely dated. Whether the two rooms share plumbing, framing or a floor.

The default that holds for most Baltimore County houses: if there is one full bathroom and something in it is failing, the bathroom goes first, because a failing bathroom has no workaround inside the house and a tired kitchen has several. If there are two full baths and neither is leaking, the kitchen usually goes first, because it governs how the house gets used every day and because it can be revisited in pieces later in a way a tile shower cannot.

What follows is the arithmetic behind that default and the cases where it flips.

Living through it: what each room takes away

A kitchen remodel takes the sink, the dishwasher, the range and the counters at once. The refrigerator usually survives, parked in the dining room or the garage on an extension cord you should not be using. People set up a card table with a microwave and an induction plate and tell themselves it is fine, and at first that is true.

The part that wears people down is dishwashing. Washing pots in a bathroom lavatory is awkward the second time and grim long before the end. A utility sink in the basement, if the house has one, changes a kitchen remodel more than anything else.

A bathroom remodel takes the shower, and that is the whole story if it is the only full bath in the house. A half bath covers the toilet and nothing else. The toilet in the room being remodeled comes out on the first day of demolition and does not go back until the plumbing final. There is no card table version of a shower.

So the honest comparison is not which project runs longer. It is whether the inconvenience has a floor under it. A kitchen project is a mild one with a workaround. A single bathroom project is a total one without.

Dust runs the other way. A bathroom closes behind a door, and a zippered containment wall there holds most of what comes off the walls. A kitchen in anything built after about 1990 opens into the family room, so containment means plastic across a twelve foot opening, and the dust finds the house anyway.

Which project takes more of the house with it

Kitchens bleed past their own footprint. The flooring usually runs continuous into the dining room and the hall, so replacing it means deciding where to stop, and the honest stopping point is often two rooms away. The soffit above the wall cabinets hides a duct or a drain often enough that nobody can promise what is in it until it is open.

Then there is the wall. In a Baltimore County Cape Cod or rambler, the wall between kitchen and dining room frequently carries the floor above it. Removing it is a structural question before a design question, and it changes the permit path for the whole job.

A bathroom does the opposite. It concentrates. Supply, drain, vent, wiring, framing, waterproofing and finish all stack inside roughly forty square feet, and every one of them disappears behind tile. The room is more difficult per square foot than any other in the house and less disruptive to the house as a whole.

One Baltimore County detail. In a postwar rancher the back door opens into the kitchen, so when the kitchen is the job site it is also the route for every delivery and every trade.

What Baltimore County asks of each room

The county treats these two rooms very differently on paper, and most homeowners have it backwards.

Baltimore County's bathroom alteration permit page says an alteration permit is required for all commercial bathrooms, that a permit is not required for residential bathrooms, and that plumbing and electrical permits are always required, with the licensed plumber and electrician permitted to apply for their respective permits before the work is initiated. A residential bath rebuilt inside its existing walls usually generates no building permit at all.

There is no matching page for kitchens. The county's addition, alteration and structural modification page requires a permit for any additions, alterations or structural modifications to existing dwellings, and separately for structural work or when a new bedroom or kitchen is created. Set beside the bathroom page, the absence is the point: the county published a residential carve-out for one room and not for the other. So a kitchen's building permit question gets answered by describing your actual scope to the Department of Permits, Approvals and Inspections in Towson and getting the answer back in writing.

Trade permits apply to both. The plumbing and gasfitting permit page requires a permit for all plumbing and gasfitting work and lets only a Baltimore County licensed plumbing or gasfitting contractor apply. The application asks for the number of fixtures that are new, replaced or removed, which is where the rooms separate: a bathroom files a water closet, a lavatory and a tub or shower, a kitchen files a sink and a dishwasher connection. The electrical permit page is similar and only slightly narrower, requiring a permit for all electrical work including the extension of circuit wiring, and exempting only ordinary maintenance of existing systems such as light fixtures and switches. Working without one is a violation subject to a civil penalty.

Two more things from that electrical page matter before you choose an order. Only an electrical contractor registered or licensed in Baltimore County can apply. And the county states plainly that existing electrical services are not required to be upgraded, though mortgage companies may want to see a minimum 100 amp, 240 volt service with circuit breakers. Residential alterations by a private contractor also require that contractor's Maryland Home Improvement License number on the application, the same number that belongs on your contract.

One jurisdiction note before you start calling. For a Baltimore County address, Permits, Approvals and Inspections is the office. That is not the pattern everywhere in this region, since an incorporated city such as Rockville in Montgomery County runs its own inspection services division and issues its own building and trade permits.

  • Building permit for a rebuild in place. Kitchen: No published residential carve-out; the alteration page governs and scope decides. Bathroom: County states a permit is not required for residential bathrooms.
  • Plumbing permit. Kitchen: Required; applied for by a county licensed plumbing contractor. Bathroom: Required; applied for by a county licensed plumbing contractor.
  • Electrical permit. Kitchen: Required for all electrical work including extending circuit wiring. Bathroom: Required for all electrical work including extending circuit wiring.
  • What pulls in the building side. Kitchen: Removing a wall, creating a new kitchen, altering floor structure. Bathroom: Cutting joists, moving a bearing wall, framing a dormer or an addition.
  • Fixtures on the plumbing application. Kitchen: Sink, dishwasher connection, sometimes a pot filler or a second sink. Bathroom: Water closet, lavatory, tub or shower, sometimes a second lavatory.
  • Living without it. Kitchen: A workaround exists; refrigerator and microwave keep the house running. Bathroom: Total loss of the shower where it is the only full bath.
  • Changing your mind later. Kitchen: Component by component, without touching the rest. Bathroom: Not without demolition back to the studs.

Which one you can change your mind about later

A kitchen is an assembly of parts with separate service lives. Cabinets, counters, backsplash, flooring, sink, lighting and the island go in on top of each other in sequence, and any one of them can be replaced later without destroying the others. New countertops can go on existing boxes. A backsplash can change without the counters moving. Cabinet replacement can happen years after the floor went in.

Cabinets are the part worth buying once, and there is a real standard behind that. Cabinets certified to ANSI/KCMA A161.1 are tested as installed per the manufacturer's instructions, with shelves and bottoms loaded uniformly at fifteen pounds per square foot and held for seven days, doors cycled twenty five thousand times with sag at the measured point limited to 0.065 inch, and drawers cycled twenty five thousand times under load without failure in the box or the slide. A certification sticker inside a door is worth asking to see.

A bathroom does not work this way. The waterproofing is one continuous assembly: pan, curb, corners, wall membrane and tile, bonded together and dependent on each other. There is no version where you change the shower and leave the rest. Swapping a vanity, a toilet or a light fixture is easy. Everything inside the wet wall is a single decision you make once.

So if you are unsure about layout, finish or how long you are staying, the kitchen is the safer room to be unsure in.

Staging: what a kitchen allows and a bathroom does not

A kitchen can be done in phases. Counters and a sink this year, cabinets later. Flooring now, the island once the layout has proven itself. Each phase that moves a fixture or extends a circuit needs its own trade permit, so phasing trades convenience for repeated applications, but it is possible, and for a household that cannot lose the kitchen in one block it is sometimes the only way the project happens.

One thing cannot be phased. If the sink is moving, it moves at the beginning or it never moves, because the drain, the vent and the supply all run inside walls and floors that get closed at the end of phase one. Layout is a day one decision in a kitchen even when nothing else is.

Bathrooms resist phasing entirely. The wet wall opens once. Tile goes over waterproofing that goes over backer that goes over a rough that has already been inspected, and that sequence cannot be interrupted and resumed later without redoing part of it. A bathroom is one block of disruption, which is a real argument for putting it first and getting it behind you.

When both are planned: the order that keeps a wall from opening twice

If the kitchen and a bathroom are both happening within a couple of years, the sequence question stops being about lifestyle and starts being about construction.

Find out first whether they share anything. In a two story Cape Cod or a rowhouse, the upstairs bathroom often sits directly above or beside the kitchen, and the kitchen ceiling is the only access to that bathroom's drain, vent and supply runs. If that ceiling is coming down anyway, it is the easiest access to the bath there will ever be. Kitchen first and bath two years later means cutting the same ceiling open twice.

Both rooms usually tie into the same stack. Cutting and transitioning cast iron, and replacing supply back toward the meter, are better done once, which argues for the two projects sitting closer together rather than further apart.

Venting is where the order can genuinely trap you. Baltimore County's plumbing and gasfitting code, adopted by Council Bill 94-23, allows fixtures in one bathroom group or two adjacent bathroom groups on the same floor level to be wet vented, and limits the wet ventable fixtures to lavatories, water closets, bathtubs, showers and tub or shower combinations. Water closets may not be drained by wet vent piping, though they may be vented by it. If a second bathroom is anywhere in the plan, that adjacency rule shapes where it can go, and it should be settled before a kitchen layout locks the plumbing wall in place.

Dust argues for the dirtier room first. In a 1950s house that is the bathroom, where mud set tile over wire lath comes off in chunks rather than sheets.

Flooring argues the other way. If the same material is running through the kitchen, the hall and into a powder room, it wants to go down in one pass with one set of transitions.

The rule that falls out of all this: open the shared assembly once, and schedule the room that depends on the other room's access first.

What the age of the house changes about the answer

The default order flips depending on the decade, and Baltimore County has three decades that cover most of its housing.

In the postwar brick Cape Cods and ramblers through Woodlawn, Lochearn and Parkville, there is usually one full bath, roughly five feet by eight, with a cast iron tub against the outside wall. Behind the plaster sits cast iron drain piping, galvanized supply that has been narrowing from the inside for seventy years, and a two wire circuit with no equipment ground. There is no exhaust fan because the window was the ventilation. The kitchen in that same house is a closed room with a wall that may be carrying the second floor, and it is usually too narrow for two people. The NKBA kitchen planning guidelines put a work aisle at not less than 42 inches for one cook and 48 inches for multiple cooks, measured between counter fronts, tall cabinets and appliances, and a postwar galley often falls short of that. The bath almost always goes first here, both because it is the only one and because the kitchen's wall question deserves a structural answer before anybody orders a cabinet.

In the 1960s and 1970s split levels around Perry Hall, Carney and the north side of Parkville, the kitchen sits on the upper half level, so the kitchen floor is the family room ceiling. That makes the kitchen the easy access point to anything running between them, and it pulls the kitchen earlier in the order. Bathrooms in those houses are often back to back across a shared wall, which is the easiest arrangement there is for touching both.

In 2005 construction in Owings Mills or Perry Hall, the plumbing is PVC and the supply is copper or PEX, the floor is engineered I-joists you cannot notch the way a sawn joist tolerates, and the tub is a one piece acrylic unit set before the walls were framed that will not leave through the door intact. The kitchen in that house is already open to the family room, so there is no wall to remove and no soffit to chase. The kitchen becomes a surface and cabinet project and the bathroom becomes the one where the structure argues back. Order follows: kitchen first, comfortably.

Remodel the bathroom you have, or add one

This is the other version of the same decision, and the answer is cleaner than people expect.

Remodeling the bathroom you have is the smaller permit package in almost every case. Fixtures get replaced where fixtures already were, the drain and vent exist, nothing new is created, and the building side of the county usually stays out of it.

Adding one creates fixtures, often creates a room, and brings in work a renovation never touches. The new drain has to reach the stack at a workable slope. The vent has to be legal under the county's adjacency rule above. The floor framing has to accept a closet bend, which is a different conversation in engineered I-joists than in full dimension lumber. Below grade, the drain cannot run by gravity to a sewer that sits above it, so the fixtures get pumped. If the new room needs framing, the building permit, construction plans and the inspections that come with them enter the project. On a property served by well and septic, the county also requires information on the adequacy of that system to go to Ground Water Management where improvements add a bedroom, add square footage or otherwise allow an increase in occupancy.

Then there is whether it fits at all. The plumbing code the county enforces sets the arithmetic. A water closet, lavatory or bidet cannot sit closer than fifteen inches from its centerline to any side wall, partition, vanity or obstruction. There must be at least twenty one inches of clear space in front of it to any wall, fixture or door. A shower compartment needs at least nine hundred square inches of interior cross sectional area and at least thirty inches in its least dimension, measured from the finished surface at the top of the threshold and held to seventy inches above the drain, with a single relief available at twenty five inches least dimension if the area reaches thirteen hundred square inches. The entry opening needs twenty two inches clear.

Those numbers turn a closet or the end of a hallway into either a bathroom or a disappointment. Draw them first.

The middle path is often the best one. A half bath converted to a full bath already has the drain, the vent and the supply in the wall, so the question collapses down to whether the room can hold a compliant shower. Likewise a tub to shower conversion in an existing bath buys back usable floor without creating a fixture or a room. What pushes any of it to the high end is the same list every time: how far the drain travels, whether the floor comes up, whether the stack gets cut, and whether this is the only bathroom in the house.

Ventilation and lead paint, on either job

Both rooms carry a ventilation requirement, and they are not the same number. The mechanical code Baltimore County adopted requires local exhaust in kitchens, bathrooms and toilet rooms: one hundred cfm intermittent or twenty five cfm continuous for a kitchen, fifty cfm intermittent or twenty cfm continuous for a bathroom or toilet room. Exhaust air may not be discharged into an attic or a crawl space, which is where many existing bath fans in these houses still terminate. Listed and labeled ductless range hoods are the narrow exception on the kitchen side, and only where ventilation is otherwise provided.

One kitchen number catches people planning a large hood. A hood capable of exhausting more than four hundred cfm has to be provided with makeup air at approximately the exhaust rate, with a means of closure and automatic controls that start it with the hood. A professional style range top quietly converts a cabinet job into a mechanical design problem.

Where these numbers live is worth knowing. Chapters twelve through twenty four of the residential code sit outside the scope of the Maryland Building Performance Standards, so the mechanical requirements come from the mechanical code the county adopted under Bill 49-24, not the residential code pages a homeowner finds first. The same holds further on for plumbing.

Natural light and air follow the rooms too. A kitchen is a habitable room and carries the eight percent glazing requirement with four percent openable, though the openable part can be dropped where a local exhaust system is installed. A bathroom needs three square feet of glazing with half openable, or artificial light plus a local exhaust system discharging directly outdoors.

Last, the rule that applies to whichever room you pick. In a house built before 1978, anyone paid to disturb painted surfaces has to be certified under the EPA's Renovation, Repair and Painting Rule, with workers trained in lead safe practices. That covers taking down painted plaster in a 1955 bathroom and pulling painted trim and old cabinets in the kitchen of the same house. EPA administers the program directly in Maryland.

What to ask before you pick an order

Ask whether the two rooms share a stack, a wall or a floor assembly, and what a plumber would want sequenced because of it. That answer changes the order more than any preference you have.

Ask which permits each scope requires and who applies for each. For a bathroom you should hear the plumbing permit and the electrical permit named, with the licensed trades pulling each. For a kitchen you should hear an honest answer about whether the building side is involved, and a willingness to describe the scope to Permits, Approvals and Inspections and get it in writing rather than guess.

Ask whether the house is pre 1978 and whether the firm holds EPA lead certification, and ask to see it rather than take the answer. Ask for the Maryland Home Improvement Commission license number in the same conversation, because it belongs on the contract and it is publicly checkable before you sign.

Ask where every exhaust fan and hood will terminate. Attic is the wrong answer in both rooms. Ask what happens if a rough inspection fails, and who carries the reinspection.

There is no universal right order, only a right order for a specific house. One full bath and a failing shower settles it one way. Two baths and a kitchen that cannot hold two people settles it the other. A shared wall between them settles it a third way, which is to plan both at once even if only one gets built this year.

Frequently Asked Questions

Should I remodel my kitchen or my bathroom first?

Count the full bathrooms before anything else. If the house has one full bath and something in it is failing, that room goes first, because there is no workaround for a lost shower and there are several for a lost kitchen. If there are two full baths and neither is leaking, the kitchen usually goes first, because it shapes daily use of the house and because it can be revisited later component by component. The exception that overrides both is a shared assembly: if the upstairs bath sits above the kitchen and the kitchen ceiling is the only access to its drain, vent and supply, plan the two together so that ceiling opens once.

Is it cheaper to remodel a bathroom or to add one in Maryland?

Remodeling the bathroom you already have is the smaller job in almost every case, because the drain, the vent and the supply are already in the wall and no new room gets created. Adding a bathroom brings in work a renovation never touches: a new drain run to the stack at a workable slope, a legal vent under Baltimore County's wet venting rule, floor framing that will accept a closet bend, pumping if the fixtures sit below the sewer, and a building permit with construction plans if the room has to be framed. On well and septic the county also wants the system's adequacy reviewed where the improvement increases occupancy. A half bath converted to a full bath is the middle path, since the rough plumbing is already there.

Do I need a permit to remodel a kitchen in Baltimore County?

Plumbing and electrical permits, yes. The county requires a permit for all plumbing and gasfitting work and for all electrical work including extending circuit wiring, and only a Baltimore County licensed plumbing contractor and a registered or licensed electrical contractor can apply for them. The building permit question is less settled for kitchens than it is for bathrooms. The county publishes a page stating that a permit is not required for residential bathrooms, and publishes no equivalent carve-out for kitchens, while its addition, alteration and structural modification page requires a permit for any alteration to an existing dwelling and specifically for structural work or when a new kitchen is created. Describe the actual scope to Permits, Approvals and Inspections and get the answer in writing.

Can I live in the house during a kitchen remodel?

Most people do. The refrigerator moves to the dining room or the garage, a microwave and a portable induction plate cover cooking, and the thing that actually determines how tolerable it is turns out to be dishwashing. A basement utility sink changes the experience more than any other single feature of the house. Plan for the dust too. A bathroom closes behind a door, but a kitchen in anything built after about 1990 opens into the family room, so containment is plastic sheeting across a wide opening rather than a closed door.

If the kitchen and the upstairs bathroom share a wall, which one should go first?

Neither in isolation. Plan them together even if only one gets built now. In a two story Cape Cod or a rowhouse, the upstairs bath frequently sits above or beside the kitchen, and the kitchen ceiling is the only access to that bathroom's drain, vent and supply. Doing the kitchen first and the bath two years later means cutting the same ceiling open twice. The sequencing rule that comes out of this: open the shared assembly once, and schedule the room that depends on the other room's access first.

Can a kitchen remodel be done in stages?

Yes, with one hard limit. Counters, backsplash, flooring, lighting and an island can each be done in a separate phase, and cabinets certified to ANSI/KCMA A161.1 are built to outlast several of those phases. What cannot be staged is layout. If the sink, the range or the dishwasher is moving, that happens at the beginning or it does not happen, because the drain, the vent and the supply run inside walls and floors that close at the end of the first phase. Every phase that moves a fixture or extends a circuit also needs its own trade permit, so staging trades convenience for repeated applications.

How much room does a new bathroom need in Baltimore County?

The plumbing code the county enforces sets the minimums. A water closet, lavatory or bidet cannot sit closer than 15 inches from its centerline to any side wall, partition, vanity or obstruction, and there must be at least 21 inches of clear space in front of it to any wall, fixture or door. A shower compartment needs at least 900 square inches of interior cross sectional area and at least 30 inches in its least dimension, measured from the finished interior surface at the top of the threshold and carried to 70 inches above the drain. A compartment with at least 1,300 square inches may go down to 25 inches in least dimension. The access opening needs 22 inches of clear finished width.

Does a bathroom fan or a range hood have to vent outside?

Yes. The mechanical code Baltimore County adopted requires local exhaust in kitchens, bathrooms and toilet rooms, at 100 cfm intermittent or 25 cfm continuous for a kitchen and 50 cfm intermittent or 20 cfm continuous for a bathroom or toilet room, and it prohibits discharging exhaust air into an attic or a crawl space. Listed and labeled ductless range hoods are the one narrow exception, and only where ventilation is otherwise provided. One number catches people specifying a large hood: a hood capable of exhausting more than 400 cfm has to be provided with makeup air at approximately the exhaust rate, with a means of closure and automatic controls.
