Bathroom Remodeling Walnut Creek CA:
Should You Keep the Tub or Build a Larger Shower?

How I Help Homeowners Decide Which Fixture Deserves the Space Before We Redesign the Rest of the Bathroom
One of the most common conversations I have during bathroom remodeling Walnut Creek, CA starts with a bathtub that nobody uses.
It may be a large built-in tub from a remodel completed twenty years ago. It may sit underneath a beautiful window and take up a surprising amount of the room. Meanwhile, the shower beside it is barely large enough to turn around in comfortably. The homeowners step around the tub every morning, clean it regularly, and use it a handful of times each year.
At some point, someone asks the obvious question: “Why are we giving this much of the bathroom to something we never use?”
That can be the beginning of a much better primary bathroom, but I do not automatically recommend removing the tub. The decision depends on what other bathrooms exist in the home, how long you plan to stay, who may use the house in the future, and what we can actually gain by taking the tub out.
If removing it lets us build a genuinely better shower, improve circulation, add useful storage, or create a bathroom that is easier to use long-term, the trade can make a lot of sense. If we are removing a tub only to build an oversized shower that consumes the same amount of space without improving anything else, I would question whether we are really making the room better.
The tub-versus-shower decision looks simple on a floor plan. In practice, it can shape almost every other part of the bathroom.
Bathroom Remodeling Walnut Creek, CA at a Glance
| What You Have Now | When I Would Consider Changing It | What I Would Evaluate First |
|---|---|---|
| Large tub and small separate shower | When the tub is rarely used and the shower feels cramped every day | Other tubs in the home, available shower footprint, plumbing, windows, and storage opportunities |
| Tub-shower combination | When easier entry or more shower space has become a priority | Whether the home has another tub, drainage, waterproofing, glass, and future accessibility |
| Freestanding tub and comfortable shower | Usually worth keeping if both are genuinely used | Clearance around the tub, cleaning access, room proportions, and long-term use |
| No tub anywhere else in the home | I would think more carefully before removing it | Children, guests, future buyers, pets, and whether another bathroom could retain a tub |
| Oversized primary bathroom with unused floor area | A larger shower may help, but size alone is not the problem | Fixture relationships, vanity storage, toilet privacy, circulation, and empty floor area |
| Older shower with a high curb | Good candidate for reconsideration during a full remodel | Floor construction, drainage, waterproofing, and whether a curbless design is practical |
| Tub beneath a valuable window | Removal may free space, but the window becomes part of the new shower design | Glass type, privacy, waterproofing, sill details, and exterior appearance |
In This Guide
This guide is for Walnut Creek homeowners who know their bathroom needs work but are not sure whether the bathtub still deserves its place in the new layout. We will look at when I think a tub should stay, when a larger shower provides more value, what removing the tub can actually give us, and the plumbing, waterproofing, permit, storage, and accessibility questions that come with the decision.
The point is not to argue that showers are better than tubs. It is to figure out which fixture your household will actually appreciate after the remodel is no longer new.
Is the Bathtub Actually the Problem?
Sometimes the room is poorly organized around it
Before I remove anything, I want to understand why the bathroom feels frustrating.
There are bathrooms where the tub clearly occupies space the homeowners would rather use elsewhere. There are also rooms where the tub gets blamed because it is the largest visible fixture, even though the actual problem is a poorly positioned vanity, a door that swings into the circulation path, or a shower that was designed badly within plenty of available space.
That distinction matters.
I have walked into large primary bathrooms where the homeowner initially wanted to remove the tub, but once we rearranged the vanity and shower on paper, the room worked comfortably with the tub still there. In another home, the tub was sitting in exactly the space we needed to create a generous shower, linen storage, and enough room for two people to move through the bathroom without crossing paths.
Both rooms had tubs. Only one needed to lose it.
This is why I prefer starting with the full layout rather than deciding the fate of one fixture in isolation. Our broader guide to what to fix first during bathroom remodeling in Walnut Creek gets into that same principle. The floor plan should answer the question before the product selections do.
When Would I Keep the Tub?
If it earns its space, I have no reason to remove it
A bathtub still makes a lot of sense for certain households.
If you actually use it, that alone is a strong argument. Remodeling should make the house work better for the people who live there, and I would not remove a fixture you enjoy because another design happens to photograph better.
I would also be cautious when the primary bathroom contains the only bathtub in the home. Families with young children often depend on one. Guests may appreciate it. Pets are another practical consideration that rarely appears in a design rendering but matters once you live with the room.
That does not mean the only tub has to be in the primary bathroom forever. If a hall bathroom already needs remodeling, we may preserve or improve the tub there and give the primary bath more flexibility.
The room proportions matter too. A bathroom that comfortably supports a good shower, useful vanity, storage, and tub without forcing anything may not need the dramatic either-or decision at all.
What I do not like is preserving a tub entirely out of fear when the homeowners have not used it in ten years and another full bath already contains one.
Does Removing the Tub Hurt Resale Value?
I would not design your entire bathroom around a buyer who does not exist yet
This question comes up almost every time we discuss a tub removal.
I understand why. Bathroom remodeling is a significant investment, and homeowners do not want to make a choice that unnecessarily limits the home later.
My answer is more nuanced than “you always need a tub.”
I care about the bathroom mix across the entire house. A home with a comfortable tub in another full bathroom is different from a home where removing the primary tub leaves no bathtub anywhere. I also consider the likely use of the property, bedroom count, and how the new bathroom functions as a whole.
A cramped primary bath is not automatically more appealing simply because it contains a tub.
If removing an underused fixture creates a significantly better shower, more storage, safer circulation, and a room that feels proportionate to the rest of the home, that improvement deserves weight too.
I would rather make an intentional trade than preserve a weak layout because of a resale rule that does not account for the actual house.
What Do You Really Gain by Removing the Tub?
The answer needs to be more specific than “a bigger shower”
This is where I want the new plan to prove itself.
Suppose we remove a five-foot built-in tub. We could use that area to extend the shower, but I want to know what the extra space changes. Can we add a comfortable bench without narrowing the entrance? Can the controls move somewhere you can reach them without stepping into cold water? Can we create better towel storage? Does the toilet gain more privacy? Can the vanity become more useful?
Maybe the removal lets us solve three problems at once.
That is a strong remodel.
Another plan might replace a perfectly usable tub with a shower so large that a third of it never gets used. The bathroom technically becomes more luxurious, but the homeowner is still storing towels in the hallway and fighting for vanity drawers every morning.
I would take the better storage every time.
A beautiful shower gets attention when someone first sees the bathroom. A drawer exactly where you need it earns its keep every morning.
How Big Should the New Shower Actually Be?
Comfortable is better than enormous
Shower size is another place where more is not automatically better.
The current NKBA planning guidelines emphasize clear floor space, access, and relationships between fixtures rather than chasing maximum dimensions. That is the right way to think about it.
I want enough room for the way you actually shower. If you want a bench, we need space for it without making the standing area awkward. If two showerheads are important, we need to understand where people stand and how the water is controlled. If the goal is easier long-term access, entrance width and curb design may matter more than adding another foot to the back wall.
I also pay close attention to the glass. A large shower surrounded by poorly placed glass can make a bathroom harder to clean and awkward to enter. Door swing, towel placement, ventilation, and where water actually travels all matter.
The shower should feel generous because it is well proportioned, not because we used every inch the old tub gave us.
Should the New Shower Be Curbless?
If you want one, decide early
Curbless showers can be an excellent choice in a primary bathroom. They remove a threshold, create a cleaner visual transition across the floor, and can make the space easier to use over time.
They also require more planning than simply choosing a different shower pan.
The floor needs proper slope. Drainage has to work. Waterproofing has to extend where it belongs. Depending on the structure, we may need to adjust the floor assembly to achieve the finished elevation without creating an awkward ramp outside the shower.
This is not a detail I like adding after demolition because someone saw a curbless shower photo the night before tile installation.
If long-term use is part of the reason you are remodeling, there are several decisions worth discussing at the same time. A handheld showerhead, comfortable controls, adequate lighting, wall reinforcement for potential future support bars, and sensible clearances can all be incorporated without making the room look institutional. AARP similarly recommends features such as easier shower access, grab-bar planning, nonslip surfaces, and improved lighting when homeowners are thinking about aging in place.
The goal is not to design for a problem you may never have. It is to avoid rebuilding the same bathroom later for something we could have planned easily while the walls were already open.
What If the Tub Is Under a Window?
That window becomes part of the shower decision
This is common enough that it deserves its own conversation.
A tub can sit comfortably below a large window because occasional splashing is very different from daily shower spray. Once we convert that area into a shower, the window has to live in a much wetter environment.
That does not automatically mean the window has to disappear. It does mean we need to evaluate the opening, sill, waterproofing, privacy, glass, and exterior appearance carefully.
Sometimes reducing or relocating the window gives us a cleaner shower. In another bathroom, the natural light is one of the strongest features in the room and preserving it is absolutely worth the extra detailing.
This is also a permit issue. Walnut Creek lists bathroom remodeling and replacement or changed windows among work that commonly requires building permits, and all permit applications submitted from January 1, 2026 forward must comply with the 2025 Building Code.
I want the window decision made on the drawings, not after the old tub is sitting in the dumpster.
What Happens to the Plumbing When the Tub Comes Out?
Keeping fixtures near their existing locations can help, but I would not let old plumbing control the entire design
Replacing a tub with a shower in roughly the same area may allow us to work close to existing supply and drainage locations. That can be simpler than moving the shower to the opposite side of the room.
But a shower drain, valve, controls, and waterproofing requirements are not identical to the tub assembly they replace. The plumbing still needs to be designed for the new fixture.
If moving the drain a reasonable distance creates a much better shower, I am willing to have that conversation. What I would not do is relocate every bathroom fixture without understanding what we are gaining for the additional construction.
This can be particularly important in slab-on-grade homes, where drainage changes may involve concrete work. In homes with accessible framing below, we may have more options, but framing and other utilities still matter.
A remodel is the time to improve the layout. It is also the time to avoid unnecessary complexity.
How Much Should You Spend on the Shower Versus the Rest of the Bathroom?
Do not let the shower consume the entire remodeling budget
The shower is easy to get excited about because it contains so many visible decisions. Tile, fixtures, glass, niches, benches, stone, drains, and controls can quickly become a large share of the project.
I want to make sure we are still spending where the room needs it.
3G’s current bathroom remodeling framework starts around $32,000 for smaller bathrooms keeping the existing layout, around $45,000 for medium bathrooms with modest layout changes, and around $80,000 for larger primary bathrooms with features such as curbless showers, custom vanities, premium surfaces, heated flooring, and upgraded millwork. Those are starting points, and the final investment depends on scope, selections, existing conditions, and how much of the room changes.
If the budget is limited, I would prioritize the things that are difficult to change later. Waterproofing, drainage, plumbing, electrical work, ventilation, floor preparation, and the correct layout belong high on that list.
A faucet can be replaced in ten years without tearing the room apart. A poorly built shower is a much larger problem.
Does Water Efficiency Matter When You Are Building a Larger Shower?
A bigger shower does not have to mean substantially more water
Fixture selection matters.
The EPA says showering accounts for nearly 17 percent of residential indoor water use. WaterSense-labeled showerheads use no more than 2.0 gallons per minute and must meet performance requirements for spray force and coverage.
That is useful because homeowners sometimes assume efficient fixtures automatically mean a disappointing shower. Performance standards have come a long way.
Where I become more cautious is when a new shower is designed with several outlets running at once. Multiple showerheads, body sprays, hand showers, and rain heads can change both water use and the plumbing requirements behind the wall.
If you love that experience and it fits the project, we can plan for it. I just want the water supply, drainage, water-heating capacity, and actual way you expect to use those fixtures considered before everything is ordered.
A feature should earn its place.
What Happens to the Space Outside the Shower?
This is where the remodel can become noticeably better
Removing a tub sometimes gives us the chance to fix the rest of the bathroom instead of pouring every recovered inch into the shower.
We might gain space for a linen cabinet near the point of use. The vanity could finally have deep drawers instead of large doors hiding plumbing. A toilet that currently sits directly in the line of sight from the bedroom may gain more privacy. We may be able to widen the circulation path or create enough clearance for two people to use the room comfortably at the same time.
These changes are not as dramatic in a rendering as a twelve-foot wall of stone.
They are often the things homeowners appreciate most once they live with the bathroom.
If the new shower becomes so large that it squeezes everything else back into the same awkward positions, I think we have missed the opportunity.
Our bathroom remodeling and renovation services are built around evaluating the whole room because shower design, cabinetry, storage, lighting, plumbing, and circulation all influence one another.
What Should You Expect From Permitting in Walnut Creek?
Plan the remodel as permitted construction from the beginning
Walnut Creek specifically lists bathroom remodels among projects requiring building permits. Plumbing, electrical, mechanical work, relocated lighting, and window changes may also be part of the permitted scope. The city now handles building permit applications through its online portal, and applications submitted in 2026 are reviewed under the 2025 Building Code.
The city also provides specific submittal requirements for single-family bathroom, kitchen, laundry, window, and door projects.
I do not view permits as something to deal with after we decide what the bathroom looks like. They belong in the planning process because the scope of work affects what needs to be documented and inspected.
That is especially true when we are changing plumbing, modifying windows, rebuilding the shower, moving walls, or altering electrical and ventilation systems.

How Would I Make the Decision in Your Bathroom?
I would ask what you use, what you tolerate, and what you want to stop working around
If we were standing in your primary bathroom, I would start with a very simple question: when was the last time you used the tub?
Then I would look at the rest of the home. Is there another tub? Who lives here now? How long do you expect to stay? Are children or grandchildren likely to use the bathroom? Does anyone have mobility concerns that make the existing shower harder to enter?
From there, I want to understand what the bathroom could become if the tub disappears. Does the shower get meaningfully better? Does storage improve? Can we create more privacy? Does the room become easier for two people to share?
If the answer is yes across several of those questions, I am usually comfortable talking seriously about removing it.
If the only gain is an unnecessarily large shower, I may tell you to keep the tub and improve the shower another way.
I do not have a rule that every primary bathroom needs a tub. I also do not have a rule that every remodel should remove one.
The house and the people living in it get a vote.
Frequently Asked Questions About Bathroom Remodeling Walnut Creek, CA
Should I remove my primary bathroom tub if I never use it?
If another bathtub exists elsewhere in the home and removing the primary tub allows the room to function significantly better, it can be a very reasonable choice. I would evaluate the whole bathroom rather than removing it automatically.
Is a large walk-in shower better for resale than a bathtub?
There is no universal answer. The overall bathroom quality, number of other tubs in the home, buyer profile, and functionality of the new layout all matter. I would focus first on creating a bathroom that makes sense for the property and household.
Can a tub-to-shower conversion be curbless?
Often, but the floor structure, drain position, waterproofing, slope, and finished elevations need to support it. Curbless shower planning should happen early in the design.
Will removing the tub make the bathroom feel larger?
It can, particularly when the tub occupies substantial visual and floor space. The improvement depends on what replaces it. A well-proportioned shower and better storage may open the room considerably.
Do I need a permit to replace a tub with a shower in Walnut Creek?
A full bathroom remodel involving plumbing, electrical work, structural alterations, or related changes should be planned through Walnut Creek’s permit process. The exact scope should be confirmed for the project.
How long does a bathroom remodel take?
3G’s current construction ranges are approximately two weeks for smaller bathrooms that keep their layout, three to four weeks for medium projects with modest changes, and four to six weeks or more for larger custom bathrooms. Design, permitting, selections, and ordering happen before those construction windows.
Should I remodel the bathroom now if a larger whole-home project is coming later?
I would look at both projects together first. If the future remodel will change the primary suite, flooring, plumbing routes, walls, or adjacent rooms, completing the bathroom independently may create work that has to be disturbed later. Our whole-home remodeling services can help put those projects into one longer-term plan.
Final Thoughts: Give the Space to the Fixture You Will Actually Use
For me, the tub-versus-shower decision is not really about which fixture is more popular.
It is about which one deserves the space in your bathroom.
If you use the tub every week, keep it and design around it well. If it is the only bathtub in the house, think carefully before removing it. If the room already has enough space for a comfortable shower, storage, vanity, and tub, there may be no reason to make the choice at all.
But if you walk past an unused tub every morning to step into a shower that is too small, the answer may already be fairly clear.
The opportunity is bigger than replacing one fixture with another. Removing the tub may allow us to improve storage, circulation, privacy, accessibility, and the way two people use the bathroom together. Those are the changes I want to see before I recommend giving anything up.
At 3G Builders & Renovation, our approach to bathroom remodeling Walnut Creek, CA starts with how you actually use the room. The tile, fixtures, glass, and finishes matter, but they come after we know the layout is worth building.
A bathroom should not keep a tub because someone told you every house needs one.
It should keep it because it still has a job.
