Two people share one sink, the shower fits one person at a time, and the corner tub mostly holds laundry. Primary bathrooms tend to carry the longest wish lists in the house, which is exactly why they need the clearest budget.

Where primary suites fall in our planning bands

For context, bathroom projects with us generally begin around $15,000, and a typical bathroom remodel comes in around $25,000. Primary suites belong with the larger projects, along with full layout changes and premium selections, which run $30,000 to $40,000.

The reason is volume. In the bathroom estimator, a large or primary bathroom is about 80 to 150 square feet or more, and that space usually holds two sinks, a roomier shower, sometimes a tub of its own, a toilet area, more tile, and more glass. Treat the band as planning guidance, since your own selections decide where you land.

A primary bath that keeps its layout and replaces its finishes is a different project from one that moves the shower and adds a freestanding tub. Both are primary suites, and the estimator asks enough questions to tell them apart.

The big decisions in a primary bath

Separate tub and shower, or one larger shower

Many primary baths pair a built-in tub that rarely gets used with a shower that feels cramped. Removing the tub to enlarge the shower is one common trade. A freestanding tub needs its own floor- or wall-mounted filler and plumbing, and heavier tubs raise questions about floor support that are evaluated in person. Compare freestanding vs built-in tubs before deciding.

One sink or two

A second sink adds a drain, supply lines, a longer vanity, and a longer countertop. It also needs enough wall length to give each person elbow room, and the single vs double vanity comparison weighs the two options.

The shower build

Size, entry, a bench, niches, glass, and the number of outlets all scale up in a primary shower. A curbless entry with a linear drain and a large fixed panel sits at the upper end, and the walk-in shower cost guide breaks those choices down one at a time. In a shared bathroom the shower is where two people’s preferences meet, so agree on the controls, the handheld, and the bench before anything is ordered.

Layout and the toilet room

Keeping fixtures in place keeps the plumbing simple. Moving the shower across the room, or enclosing the toilet in its own small room, adds drain work, a wall, a door, and often a separate fan and light. Wall changes and drain relocation on a slab are evaluated during the in-home consultation, since they involve engineering or licensed plumbing trades.

Finish level and comfort features

Natural stone, handmade tile, and large porcelain panels push the number up, and so do premium valves and lighting. Electric floor heating goes under the tile and often needs its own circuit, which involves licensed electrical trades and is evaluated during the consultation.

Questions to settle before you price it

A primary bath gets expensive when it’s designed around a wish list instead of a routine. A few honest answers keep the plan grounded:

• Do two people get ready here at the same time? That decides two sinks, a separate toilet area, and how much counter you need.

• Does anyone actually take baths? That decides whether a tub earns its floor space.

• What has to be stored here? Towels, linens, and daily items need drawers and cabinets, not just a counter.

• Will anyone need easier access later on? That shapes the shower entry, the bench, and the grab bar backing.

• Is there a window in or near the shower? It needs careful waterproofing and may need safety glass, which the consultation checks.

Spend where you’ll feel it every day

In a primary bath, the things you use every morning matter more than the things you photograph. Rank your wish list by daily use and put the budget there first:

• A comfortable shower, with the controls and a handheld where you can reach them

• Drawer storage at each sink, plus a place for towels and linens

• Layered lighting at the mirror, not just one fixture overhead

• An exhaust fan sized for a larger room and a larger shower

• A tub only if someone will actually use it

The photogenic pieces still have a place. Choose one, like a statement light fixture or a feature wall of specialty tile, and let the rest of the room support it rather than spreading premium choices across every surface.

Build in easier access now

Since the walls are open anyway, this is the cheapest moment to make the room easier to use down the road. A low or curbless shower entry, wood blocking for grab bars, a bench, a handheld on a slide bar, lever handles, and slip-resistant floor tile cost far less to build in now than to retrofit. The aging-in-place bathroom checklist is a good place to start.

Mistakes that inflate primary bath budgets

• Designing in pieces. Picking tile before deciding on the glass, niches, and bench means reworking the plan, or the order.

• Deciding on the toilet room late. A wall added after rough plumbing means redoing work.

• Copying a photo without measuring. A layout drawn for a bigger room can crowd yours, so plan clearances first.

• Overlooking ventilation. A bigger shower in a bigger room needs a fan that can clear the steam, or the new paint and grout pay the price.

• Underestimating glass. Large frameless panels are custom pieces, measured after tile and priced on their own.

Pricing your primary suite

Choose Large / Primary Bathroom in the bathroom estimator, then answer the rest, from scope and the shower or tub through tile, vanity, layout, plumbing and electrical, and finish level. If you pick a custom tile shower, it also asks about glass. Torn between keeping the tub and enlarging the shower? Run the estimator once with each choice and see how the range responds.

The planning range you see reflects those selections. A free in-home consultation then confirms the floor structure, plumbing routes, electrical needs, and permits, and you can read more about primary bathroom remodels in the meantime.
