Shower vs Bathtub: Cost, Water Use, Resale, and Which to Choose

Shower vs bathtub comes down to your household: a shower costs less to run and saves water, while keeping at least one bathtub protects resale, especially with families.

Shower vs bathtub: which should you pick?

Pick a shower if you want lower water use, a smaller footprint, and easier step-in access, and a bathtub if you soak, have young kids, or own the home’s only full bath. The safest play in most homes is to keep at least one tub and put the walk-in shower in a second or primary bath. Before swapping either bathroom, check tub to shower conversion costs to see how pricing shifts by tier, drain type, and project timeline.

This is rarely an either-or for a whole house. The real decision is per bathroom: which fixture earns the space, the budget, and the resale protection. The table below lines up the seven factors that actually move the answer, and if you are relocating a drain or valve, see what a bathroom remodel involves when you move fixtures.

How much does a shower vs bathtub cost to install?

A bathtub is usually the cheaper install. A standard alcove tub with a surround often runs $400 to $8,000 installed, while a walk-in shower typically runs $3,000 to $15,000 once you add waterproofing, a pan or tile, and glass. A basic prefab tub-shower unit narrows the gap, and a tiled or curbless shower widens it.

Most of a shower’s extra cost is the waterproofing and finish work, not the plumbing. Both fixtures use a similar supply and drain rough-in, so relocating either one is where the plumbing bill grows. See bathroom rough-in dimensions and pipe sizes before you plan a move.

Does a shower or bathtub use more water?

A typical shower uses less water than a bath. The average 8-minute shower runs about 16 to 20 gallons depending on the head, while a full bath commonly takes 35 to 50 gallons, per EPA WaterSense. A WaterSense showerhead capped at 2.0 gpm saves about 4 gallons per shower over a standard 2.5 gpm head.

Length is the variable that flips this. A long 15 to 20 minute shower can match or beat a full bath, so the fixture alone does not settle it. The chart below shows the per-use gap at typical shower lengths.

Which adds more resale value, a shower or a bathtub?

Keep at least one bathtub in the home for resale. Agents widely advise it, because many families with young children will not buy a house with no tub, and in competitive markets a tub-less home can draw offers $5,000 to $10,000 lower. Beyond that one tub, a well-built walk-in shower can be a net plus in a primary or secondary bath.

The math changes with your bathroom count. If you have only one full bath, keep it as a tub or tub-shower combo. With two or more full baths, converting the secondary one to a shower is low risk. A mid-range bathroom remodel returns roughly 60 to 70 percent at resale, in line with the National Association of Realtors range.

Is a shower or bathtub better for accessibility and aging in place?

A low-threshold or curbless shower is safer for aging in place. Stepping over a high tub wall on a slick surface is a leading fall risk for older adults and anyone with limited mobility, so a walk-in shower with a low or zero threshold reduces that risk. Grab bars, a fold-down bench, and a comfort-height setup add roughly $500 to $1,500. Once you’ve settled on an accessible layout, choosing fixtures matters too, from shower head options that suit a seated or standing user to bathtub styles and materials if you’re weighing a walk-in tub instead.

A zero-threshold roll-in shower with a linear drain, seat, and grab bars is the strongest accessibility option, though it costs more and needs the drain reworked into the floor. Basic accessibility features often add only a few hundred dollars to a remodel already underway.

Which is easier to clean and maintain?

Both take work, in different ways. A glass shower shows water spots and needs the door and tile wiped to keep soap scum and grout mildew down, while a tub holds less standing water day to day but is bulkier to lean into and scrub. Grout lines are the maintenance weak point in a tiled shower.

The easiest to keep clean is a curbless shower with large-format tile and minimal grout, or a solid-surface acrylic pan and walls. A slow tub drain is a common tub headache; here is how to clear a slow bathtub drain before it backs up.

How much does a tub-to-shower conversion cost?

Most tub-to-shower conversions run $2,000 to $12,000, with a mid-range job around $6,500 in 2026. A prefab acrylic kit runs about $2,000 to $6,000, a tiled walk-in $6,000 to $12,000, and a curbless roll-in shower $8,000 to $15,000. Reusing the existing drain and valve keeps the plumbing bill down.

The conversion gets more expensive when the drain has to move, since a tub drain sits in a different spot than a shower drain and a curbless pan needs the floor reframed to slope. To see how the valve and drain lay out, review how a shower valve and drain rough-in works.

Who should choose a shower, and who should keep a bathtub?

Choose a shower if you rarely soak, want lower water use, have a tight footprint, or are planning for aging in place, provided the home still has a tub somewhere. Keep or add a bathtub if you bathe young children, like to soak, or own the home’s only full bath, where the resale tub rule applies most strongly.

In single-bathroom homes, the tub-shower combo is still the smartest default: it fits both fixtures in a 5-foot alcove and protects resale. Reserve the standalone walk-in shower or separate soaking tub for homes with the bathroom count and floor space to spare.
