Curbless Showers: Are They Worth It in Chicagoland Homes?

If you've been researching bathroom remodels lately — maybe flipping through photos from a project in Hinsdale or Western Springs — you've probably come across the term "curbless shower" and wondered if it's just a design trend or something worth the investment. It's one of the most common questions we get from homeowners in Burr Ridge, Oak Brook, and the surrounding suburbs, and the honest answer is: it depends on your home, your goals, and how long you plan to stay in it. Let's break down what a curbless shower actually is, what goes into building one correctly, and who tends to benefit most.

What a Curbless Shower Actually Is

A curbless shower (sometimes called a zero-threshold or barrier-free shower) is exactly what it sounds like — there's no raised lip or curb separating the shower floor from the rest of the bathroom. Instead of stepping over a 4-6 inch threshold, you walk straight in, often on a continuous tile surface. The floor is sloped subtly toward a drain — usually a linear drain along one wall — so water stays contained without a physical barrier.

It's a very different approach from a traditional shower pan, and it changes how the whole bathroom floor is built, not just the shower itself.

Why Homeowners Want Them

A few reasons come up again and again in our consultations:

Aging in place. Many of our clients in established neighborhoods like Clarendon Hills and Indian Head Park are remodeling homes they plan to stay in for decades. A curbless shower removes a tripping hazard and makes the bathroom usable for anyone with mobility limitations now or in the future — without it looking like a clinical, "accessible" bathroom. Done well, it just looks like a beautiful, open shower.

Clean, modern look. Even for homeowners with no accessibility concerns, there's a real aesthetic appeal. A curbless shower makes a bathroom feel larger and more open, especially in the primary suites common in Palos Park and Western Springs homes where square footage is sometimes tighter than buyers expect.

Easier cleaning. No curb means no grout line and caulking seam constantly collecting grime and mildew.

What's Actually Involved (This Is the Important Part)

This is where we want to be upfront with homeowners, because curbless showers are frequently oversimplified online. A curbless shower isn't just "remove the curb" — it requires rebuilding the floor structure to create proper drainage slope across a larger area, which has real implications:

Floor framing and height. To get a smooth, sloped transition without a curb, the shower floor and the bathroom floor often need to meet at the same level, which may mean lowering the shower drain area into the subfloor — sometimes requiring floor joists to be notched or a recessed pan to be built in. In homes with concrete slab foundations (less common in our area, but it happens) or in second-floor bathrooms with limited joist depth, this takes careful planning. In many older homes throughout Hinsdale and Western Springs with original joist framing from decades back, we sometimes have more flexibility than you'd expect, but it always requires an on-site evaluation.

Waterproofing. Because there's no curb acting as a secondary containment barrier, the waterproofing membrane under the tile has to be done correctly across the entire floor, not just inside the shower area. This is one part of the job where cutting corners causes real problems — water finding its way under flooring or into a ceiling below is a far more expensive fix than the shower itself.

Linear drains and slope. Linear drains along one edge of the shower allow for a slope in a single direction, which tends to look cleaner and work better in a curbless design than a traditional center drain.

Glass and layout. Many curbless showers use a single fixed glass panel instead of a full enclosure, which depends on good layout planning so water doesn't splash out into the rest of the bathroom.

None of this means a curbless shower isn't doable in your home — the vast majority of the time, it is. It just means it's a more involved renovation than a standard shower replacement, and it benefits from being planned by someone who's done the framing and waterproofing correctly before.

Is It Worth the Cost?

Curbless showers generally cost more than a standard shower replacement because of the floor modification and waterproofing work involved. We'd rather not throw out a specific number here, because it genuinely varies based on your existing floor structure, the size of the shower, tile selections, and whether other parts of the bathroom are being touched at the same time. A homeowner doing a full bathroom remodel that includes a curbless shower will see different numbers than someone trying to convert just the shower in an otherwise untouched bathroom.

What we can tell you: if you're already planning a full bathroom renovation, the incremental cost of going curbless is often more reasonable than tackling it as a standalone project later, since the floor is already being opened up. If accessibility, resale appeal, or long-term comfort matter to you, it's a feature that tends to hold its value well in this market — move-up buyers in Oak Brook and Burr Ridge increasingly expect a well-designed primary bathroom, and a curbless shower reads as a thoughtful, higher-end detail rather than a niche accessibility feature.

Timing in the Chicago Area

Bathroom remodels are mostly indoor work, so they're not as weather-dependent as something like an addition or exterior renovation. That said, we find late fall and winter are popular times for homeowners to tackle bathroom projects, since there's less competition for scheduling compared to spring and summer when kitchen and full-home projects pick up.

If you want to see what a curbless shower looks like finished, our gallery has examples from recent bathroom projects around the western suburbs. And if you're weighing whether it makes sense for your specific bathroom layout, that's really a conversation best had in person, with someone looking at your actual framing and plumbing.
