Is a tub-to-shower conversion worth it?

The clearest case for keeping a tub is a household with young children, if that tub is the only bathtub in the home. Bathing small children is genuinely easier and safer in a tub than in a shower, and if you convert your only tub, you have not simply changed a fixture, you have removed a capability from your home that is difficult and expensive to add back later if your household composition changes again.

Resale consideration in family-oriented neighborhoods is the second reason to think twice. In suburban areas across the south Salt Lake Valley and parts of Davis County where homes are frequently purchased by families with young or future children, real estate agents will tell you that a home with zero bathtubs can be a genuine, if not universal, point of hesitation for that specific buyer pool. If your home has multiple bathrooms and you are converting one of several tubs, this consideration mostly disappears, because at least one tub remains in the house.

There is also a simpler case for keeping a tub: some people genuinely use and enjoy theirs, for actual bathing, not just as a shower enclosure with a lip. If that describes you, a shower conversion removes something you actually value in exchange for a look that might be more contemporary but is not actually a functional improvement for how you live.

The most common and most straightforward case is a garden tub or oversized soaking tub that has gone unused for years. These were popular installations in primary bathrooms built in the 1985 to 2005 window across much of the south Salt Lake Valley, and in practice, many homeowners tell us they have used theirs a handful of times total since moving in. An unused tub occupying twenty or more square feet of a primary bathroom is not a feature, it is dead floor area, and converting it to a shower or removing it in favor of a larger walk-in shower typically transforms how the whole room feels to use daily.

Aging in place is the second clear case, and it is one we take seriously because the planning has to happen before it is urgently needed, not after. Stepping over a tub wall becomes a genuine fall risk as mobility changes with age, and a properly built curbless or low-threshold shower with a bench and blocking in the walls for a future grab bar removes that risk entirely while also being comfortable and attractive well before anyone needs the safety features specifically.

Tight pre-war footprints in older Salt Lake City neighborhoods present a third clear case. Many of these bathrooms were built around a single, undersized tub-shower combination in a room barely wide enough to turn around in. Converting to a properly proportioned shower, even a compact one, in these rooms frequently makes the difference between a bathroom that feels cramped every single day and one that feels intentionally designed, simply by removing the awkward geometry a decades-old tub imposes on a small footprint.

A tub-to-shower conversion is not a matter of unbolting a tub and setting a shower pan in its place, even though it is sometimes marketed that way. The tub is removed, and the area is opened up to the framing, because the waste connection, the wall structure, and the waterproofing all need to be evaluated and typically redone rather than reused, regardless of how good the existing tub surround looks from the front.

Waterproofing is the part that matters most and shows least. A shower has a much larger area of continuously wetted wall and floor surface than a tub does, particularly near the floor and at the transition to the room, so the waterproofing system installed has to be rated and installed correctly for that continuous exposure, not simply extended from whatever membrane, if any, was behind the original tub surround.

Depending on the shower design chosen, framing may need to be adjusted to create a niche for shampoo storage, a bench, or blocking for a fixed glass panel or grab bar, none of which existed in the original tub installation. This is also the stage where any electrical near the new shower location, most commonly lighting, gets evaluated for whether it meets the wet-location standard now that the water exposure pattern in the room has changed.

The tub drain and the shower drain are not simply interchangeable even though both eventually connect to the same waste system, because a shower drain is typically positioned differently within the floor plan and, in some layouts, needs a different pitch or a larger drain assembly than what a tub required. Whether the existing drain location can simply be reused or needs to move is one of the first things we assess, because it materially changes both the cost and the construction sequence.

In slab-on-grade homes, common across the west side of the Salt Lake Valley and in many Davis County subdivisions, moving or resizing a drain means cutting into the concrete slab, since there is no accessible space beneath the floor to work from. This is legitimate, well-established construction, but it is more disruptive and takes longer than a conversion where the existing drain location and size can be reused as-is.

In homes with basement or crawlspace access beneath the bathroom, which is more common in older housing stock and split-level homes, a plumber can often access and adjust the drain from below without cutting the finished floor at all, which keeps the project meaningfully faster and less disruptive. This is one of the reasons the same conversion can cost noticeably different amounts in two houses that look similar from the bathroom itself.

A curbed shower has a raised lip at the entry that helps contain water within the shower area using gravity and a shallow physical barrier, and it is generally the simpler and less expensive of the two approaches to build correctly, because it does not require altering the floor structure beyond the shower footprint itself.

A curbless, or zero-threshold, shower requires the floor to transition smoothly from the surrounding bathroom floor into the shower with no step, which usually means the subfloor needs to be modified to create a very gradual, properly waterproofed slope toward the drain across a larger area than just the shower pan itself. This is more involved construction, and in a slab-on-grade home it often means recessing or building up the surrounding slab area, which is a bigger undertaking than a curbed shower in the same footprint.

The decision genuinely comes down to priorities rather than one option simply being superior. Curbless showers are the clear right answer for aging-in-place planning, wheelchair or walker accessibility, and a more contemporary, open visual line in the room. Curbed showers remain a completely reasonable, well-proven choice for households without an accessibility priority, and they are meaningfully less disruptive to install, particularly on a slab.

A well-built shower conversion in a primary or guest bathroom generally reads well to buyers, particularly when it replaces a tub that was clearly oversized, dated, or awkwardly placed for the room. Buyers respond to a bathroom that feels current and well-proportioned, and an unused garden tub converted into a spacious shower is frequently one of the more visually persuasive changes a bathroom remodel can make.

What it does not reliably do is add value in a way that is separable from the rest of the bathroom's condition and design. A conversion is one part of a bathroom's overall impression, not a standalone value driver, and its impact depends heavily on the quality of the execution, the tile and fixture choices, and how the rest of the room reads alongside it. There is no reliable, honest figure we can quote you for how many dollars a conversion alone adds, because it is not a fixture swap with a fixed return, it is a design decision embedded in a larger room.

The one place where converting can work against you rather than for you is if it removes the last bathtub in the entire house. In that specific situation, some portion of the buyer pool, particularly families actively looking for a home to raise young children in, may see the absence of any tub as a drawback worth factoring into their offer, even if the shower itself is beautifully built. If you have more than one bathroom, keeping at least one tub somewhere in the house is a simple way to convert your primary bathroom freely without that particular downside.

Start with how the tub is actually used today, honestly, rather than how it might theoretically be used someday. If it has genuinely gone unused for a year or more and nothing in your near-term household plans suggests that changing, that is a strong signal in favor of converting. If it gets used regularly, even occasionally, for bathing children or for actual soaking, that is a strong signal to keep it, at least in that particular bathroom.

Next, count your bathtubs across the whole house, not just the one bathroom you are focused on remodeling. If you have two or more full bathrooms and at least one other has a tub, converting the bathroom in question carries essentially none of the household-capability downside and mostly comes down to design preference and daily usability. If this is your only bathtub in the entire house, the decision deserves more weight regardless of how appealing the shower photos look.

Finally, have an honest conversation with your contractor about what the drain and floor situation actually is in your specific house before you settle on curb versus curbless or commit emotionally to a particular layout, since foundation type and existing drain position can meaningfully change both the cost and the construction approach available to you.
