Things to Consider Before Remodeling Your Bathroom – This Old House

Thinking about remodeling your bathroom? Before you start smashing tile with a sledgehammer like you’re on a home makeover show, take a breath. A bathroom remodel is one of the most rewarding home upgrades you can tacklebut it’s also one of the easiest places to blow your budget, forget a code requirement, or create a layout you’ll regret every single morning. Inspired by the practical, no-nonsense approach of This Old House, this guide walks you through the big things to consider before you remodel your bathroom.

Clarify Your Goals: What Do You Really Want From This Remodel?

Before you pick grout colors, get clear on why you’re remodeling. Are you trying to:

• Update an outdated space stuck in the 1980s?
• Improve resale value before listing your home?
• Create a safer, more accessible bathroom for aging in place?
• Steal back storage and organization in a chaotic family bath?
• Turn your primary bath into a mini spa where you can actually relax?

Your goals shape everything: layout, fixtures, materials, lighting, and of course, cost. A bathroom renovation focused on good resale value might lean toward timeless finishes and neutral colors. A forever-home remodel can justify splurges like heated floors, a larger walk-in shower, or custom storage that fits your exact routines.

Know Your Budget (And Then Add a Cushion)

Let’s talk money. Bathroom remodel costs vary widely depending on size, location, and finishes, but even a modest update can add up quickly. It helps to break the budget into categories instead of thinking of just one big number:

• Labor: Often 40–60% of the total cost, especially if you’re moving plumbing or electrical.
• Plumbing fixtures: Toilets, sinks, faucets, shower valves, and tubs.
• Surfaces: Tile, waterproof backer board, flooring, countertops, and paint.
• Cabinetry and storage: Vanities, medicine cabinets, built-ins, and shelving.
• Lighting and ventilation: Overhead lights, sconces, fans, and wiring upgrades.
• Permits and inspections: Required in many areas for structural, electrical, or plumbing work.

Home improvement pros often recommend adding at least 10–20% for surprisesbecause you’ll probably meet at least one. Hidden water damage behind the shower, undersized vents, or old wiring that isn’t up to current code can derail a tight budget.

Having a realistic budget upfront helps you prioritize: maybe you splurge on a quality shower system and tile, then save with a ready-made vanity instead of a fully custom cabinet.

Understand the Scope: Cosmetic Refresh vs. Full Gut Remodel

Not every bathroom needs a wall-to-wall makeover. Consider how deep your remodel needs to go:

Cosmetic Update

This is the “new outfit” version of a bathroom renovation. You keep the layout, plumbing locations, and basic structure the same but update surfaces and fixtures:

• New vanity, faucet, and mirror
• Fresh paint and updated hardware
• Refreshed lighting and exhaust fan
• New flooring or reglazed tub

A cosmetic remodel is more budget-friendly and usually quicker. It’s perfect if your bathroom functions fine but looks tired.

Full Gut or Layout Change

This is the heavy-lift remodel: walls may come down, plumbing lines move, and everything gets replaced. You might:

• Swap a tub-shower combo for a walk-in shower
• Move the toilet to a more private location
• Steal space from a closet or adjacent room to enlarge the bathroom
• Upgrade old wiring, insulation, and ventilation behind the walls

These projects require more planning, higher budgets, and often permits and inspections. But they can dramatically improve function, comfort, and long-term home value.

Plan the Layout Carefully

A beautiful bathroom with a bad layout is like a fancy sports car with square wheelspretty, but annoying to use. Designers and remodelers often point out the same layout mistakes again and again: toilets directly in your sightline when you open the door, cramped shower stalls, or vanities that collide with doors.

Before remodeling your bathroom, think about:

• Traffic flow: Make sure you can move easily between the door, vanity, toilet, and tub or shower.
• Clearances: Building guidelines typically call for minimum space in front of toilets, vanities, and showers so they’re comfortable to use.
• Shower size: A 3-by-4-foot shower is often considered a comfortable minimum for adults; squeezing it smaller can feel tight.
• Toilet placement: If possible, tuck the toilet behind a half-wall, in a separate water closet, or at least out of direct view from the hallway.
• Door swing: Consider pocket doors or outward-swinging doors in small spaces so you’re not dodging a door every time you walk in.

Creating a simple floor plan sketch with measurements is incredibly helpful. Many homeowners work with a designer, architect, or design-build contractor to refine the layout before any demo starts.

Plumbing, Electrical, and What’s Behind the Walls

One of the biggest “things to consider before remodeling your bathroom” is everything you can’t see yet. A gorgeous tile job won’t matter if the pipes behind it are corroded or the wiring can’t safely support your new lighting and outlets.

Plumbing Considerations

• Old galvanized or corroded pipes may need replacement to prevent leaks.
• Moving a toilet or shower drain often requires cutting into the floor and may trigger additional permit requirements.
• Modern shower systems (rain heads, body sprays) may need upgraded supply lines and pressure-balancing valves.

Electrical and Lighting

• GFCI-protected outlets are essential near sinks and sometimes required by code.
• Adding a heated floor, steam shower, or built-in bidet may require a dedicated circuit.
• Layered lightingoverhead, task, and accentcreates a safer, more functional bathroom.

This is where a licensed plumber and electrician pay off. Their work isn’t just about convenience; it’s also about safety and compliance with local building codes.

Ventilation and Moisture Control: The Unsung Heroes

Bathrooms are moisture factories. Long showers, steamy baths, and poor ventilation can lead to mold, peeling paint, and damaged drywall. Before you remodel, figure out how you’ll keep humidity under control.

• Exhaust fan: Choose a properly sized, quiet fan rated for your bathroom’s square footage. Many homeowners upgrade to a fan with a humidity sensor or timer so it runs long enough to clear the air.
• Ducting: The fan should vent all the way outside, not just into the attic. Dumping moist air into the attic can cause major issues down the road.
• Windows: While nice for natural light, windows alone are rarely enough for ventilation in a modern bathroom.
• Waterproofing: Behind the tile, showers need a sound waterproofing systemlike a membrane, properly installed backer board, and sealed seamsso water doesn’t sneak into the walls.

Good ventilation and waterproofing aren’t flashy, but they protect your investment and prevent the classic “We just remodeled this bathroomwhy is there mold already?” problem.

Choose Durable, Bathroom-Friendly Materials

Bathrooms are small, but they work hard. Surfaces get hit with water, steam, cleaning products, and daily wear and tear. When you’re comparing materials, don’t just ask, “Is it pretty?” Ask, “Will it still look good after five years of use?”

Flooring

• Porcelain and ceramic tile: Classic choices that handle moisture well when installed correctly.
• Luxury vinyl tile or plank: Some high-quality products are waterproof and softer underfoot than tile.
• Skip wood and carpet: These are more vulnerable to moisture and spills.

Walls and Showers

• Tile offers endless style options but requires proper prep and grout maintenance.
• Solid-surface panels or one-piece surrounds can be easier to clean in busy family bathrooms.
• Use mildew-resistant paint in non-tiled areas to help keep walls fresh.

Vanity, Countertops, and Storage

• Choose vanities designed for humid spaces with sealed finishes.
• Quartz, solid surface, and some natural stones are popular countertop choices; just be sure you’re comfortable with the maintenance they need.
• Built-in or recessed storage, such as medicine cabinets and wall niches, keeps clutter off counters.

Trendy colors and finishes are fun, but consider how fast they might date the space. Neutrals for the big-ticket items and bolder choices in towels, art, or rugs lets you refresh the look without another full remodel.

Lighting: See Yourself in the Best Light

Lighting is one of the most underrated elements in bathroom renovation. The right lighting can make a small bathroom feel bigger and more invitingand keep you from doing your makeup in shadows.

• Overhead/ambient lighting: A ceiling fixture or recessed lights provide general illumination.
• Vanity lighting: Sconces at eye level on either side of the mirror, or a well-designed light above the mirror, reduce harsh shadows on your face.
• Accent lighting: LED strips under the vanity, in niches, or around mirrors add a spa-like feel and work as night-lights.
• Color temperature: Many people prefer warm white (around 2700–3000K) for a flattering look that still feels bright.

As you plan the layout, note exactly where you’ll want light switches and dimmers. Good lighting design is a small detail that makes a big difference in daily life.

Storage and Organization: Future You Will Be Grateful

If you’ve ever balanced a shampoo bottle on the edge of a tub or knocked your skincare lineup into the sink, you already know storage matters. Think through everything that needs a home in your bathroom:

• Towels and washcloths
• Everyday toiletries and makeup
• Cleaning supplies and extra toilet paper
• Hair tools, shaving gear, and grooming accessories
• Kids’ bath toys (if applicable)

Consider options like:

• Vanities with deep drawers instead of just doors
• Recessed medicine cabinets with mirrors
• Built-in shower niches and corner shelves
• Over-the-toilet shelving or a shallow linen cabinet
• Hooks and towel bars placed where people actually use them

Planning for storage during the design phase saves you from buying random organizers later and helps keep your newly remodeled bathroom from looking cluttered.

Permits, Codes, and Safety

It’s tempting to skip permits to save time or money, but that shortcut often backfires. Many cities require permits for bathroom remodels that involve structural changes, moving plumbing lines, updating electrical circuits, or installing new waterproofing systems.

Why permits matter:

• Inspectors help verify that plumbing and wiring meet safety standards.
• Permitted work is easier to document when you sell your home.
• Some insurance policies may not cover damage caused by unpermitted work.

Before you remodel your bathroom, check with your local building department or talk to your contractor about which permits you’ll need and who’s responsible for pulling them. It’s not the most exciting part of a bathroom remodel checklist, but it’s one of the most important.

DIY vs. Hiring a Pro

Plenty of homeowners can tackle parts of a bathroom renovationpainting, demo, installing accessories, or even tiling if they’re comfortable with it. But other tasks are usually best left to the pros:

• Moving or adding plumbing lines
• Running new electrical circuits or adding heated floors
• Major structural changes, like moving walls or changing window sizes
• Complex waterproofing systems in showers or wet rooms

When hiring a contractor, get multiple bids, check references, verify licenses and insurance, and make sure you have a detailed written contract. Look for someone who communicates clearly and is willing to walk you through their bathroom remodeling process step-by-step.

Timeline and Living Through the Remodel

Even a small bathroom remodel can disrupt your daily routine. Ask your contractor for an estimated timeline and build in some flexibility for delays (materials, inspections, hidden issues). If this is your only full bath, you may need to plan temporary alternatives for showering or schedule the project when you can stay elsewhere for a few days.

A simple way to stay sane: create a “survival kit” with toiletries, medications, and essentials that you can easily move around the house. Protect nearby rooms with plastic sheeting and floor protection, and expect dustlots of dust.

Style, Personality, and That This Old House Feel

Finally, make sure your new bathroom feels like it belongs in your home. Classic This Old House-style renovations respect a home’s age and character while upgrading function and comfort. That might mean mixing traditional materialssubway tile, hex flooring, shaker-style vanitieswith modern touches like a frameless shower or sleek fixtures.

Ask yourself:

• Does this design make sense with the rest of the house?
• Will I still like this five or ten years from now?
• Have I balanced personal style with broad appeal in case I sell?

Done right, a bathroom remodel makes your daily routines easier, more comfortable, and a little more enjoyable. Done wrong… well, that’s how you end up complaining about a too-small shower for the next decade.

Real-Life Experiences: Lessons Learned From Bathroom Remodels

To make this guide even more practical, let’s walk through some common real-world experiences homeowners share after remodeling their bathroomsthe “I wish I’d known that” moments you can learn from before you pick up a hammer.

Experience 1: The Surprise Behind the Tile

Many homeowners say the biggest shock in their bathroom remodel wasn’t the final billit was what they found inside the walls. Once the old tub surround or shower tile comes down, it’s not unusual to discover:

• Rotten studs from long-term leaks
• Mold growth behind improperly sealed tile
• Random patchwork plumbing from previous DIY jobs

The lesson? When you’re setting your budget, assume you’ll spend money on repairs you can’t see yet. Hiring a contractor familiar with older homes (the kind This Old House loves to feature) can help you anticipate and handle those surprises correctly instead of covering them up again.

Experience 2: The “Pretty but Impractical” Problem

It happens all the time: someone falls in love with a beautiful freestanding tub, patterned floor tile, or wall-mounted faucet they saw online. After the remodel, they realize:

• The tub rarely gets used and is hard to clean around.
• The high-contrast floor shows every speck of lint and water drop.
• The wall-mounted faucet makes simple repairs more complicated.

Design inspiration photos are great, but think through how each feature works in real life. Ask yourself, “Who uses this bathroom every day, and what do they actually need?” A family with small kids may appreciate a simple tub-shower combo more than a dramatic wet room. A busy couple might prioritize double sinks and extra storage over a soaking tub they’ll never have time to enjoy.

Experience 3: Underestimating Lighting and Mirrors

Another common regret is not putting enough thought into lighting and mirrors. People often install one centered vanity light and a basic mirror, only to find the space feels flat and their reflection looks… not great.

Homeowners who are happiest with their remodel often say:

• They added sconces at eye level to reduce shadows.
• They chose mirrors appropriately sized to the vanity, not just whatever was on sale.
• They used dimmers to shift from bright morning light to softer evening light.

Good lighting and a quality mirror don’t just look more polishedthey make the bathroom more pleasant to use every single day.

Experience 4: Storage Is Never an Afterthought

Ask people what they love most about a successful bathroom remodel, and “storage” comes up a lot. Recessed niches, deeper vanity drawers, and well-placed hooks can transform a busy bathroom from chaotic to calm.

On the flip side, skipping storage planning often leads to regret. Homeowners end up adding cluttered over-the-door racks, baskets on the floor, or countertop organizers that crowd the sink. The lesson: build storage into the design. A slightly smaller sink to fit wider drawers might serve you better than a huge basin you rarely fill.

Experience 5: The Value of a Good Contractor

One of the most consistent takeaways from remodel veterans is this: a great contractor is worth the time it takes to find them. Homeowners who had a smooth experience usually mention that their contractor:

• Explained what was happening at each stage
• Flagged potential issues early instead of hiding them
• Respected their home and kept the work area as tidy as possible
• Offered practical suggestions based on experience, not just what was trendy

If you’re inspired by the thoughtful, craftsmanship-forward approach of This Old House, look for someone with the same mindsetsomeone who cares about what’s behind the tile as much as the tile itself.

Final Thoughts
