A curb is the low wall at the shower entry that keeps water in. A curbless — or roll-in — shower removes it, so the shower floor is flush with the bathroom floor. It looks seamless and modern, and it is the single most important feature for an accessible bathroom. But going curbless changes how the floor is built, which is why the decision is as much about your home's structure as your taste.
The trade-off in one sentence: curbless is the more accessible, more modern option that asks more of the floor framing; a curbed shower is simpler, more forgiving, and less expensive to build in an existing bathroom.
Advantages
- No lip to step or trip over — the safest entry as we age.
- Fully wheelchair- and walker-accessible as a roll-in shower.
- A seamless, open, modern look that makes a bathroom feel larger.
- Easier to clean, with the floor flowing straight into the shower.
Trade-offs
- The subfloor usually must be recessed or built up so the shower can slope to drain.
- More design and labor to keep water in without a curb — often a linear drain.
- Generally costs more than adding a standard curb.
- Retrofitting into an older home can mean structural floor work.
Advantages
- Simpler and less expensive to build in an existing bathroom.
- The curb reliably keeps water in without special floor design.
- Works over a standard floor without recessing the subfloor.
- A proven, forgiving detail in almost any layout.
Trade-offs
- The curb is a step-over — a genuine trip hazard for some households.
- Not accessible for a wheelchair or walker.
- Reads as more traditional than a flush, curbless entry.
- A raised edge to clean around rather than a continuous floor.
The deciding questions are how much accessibility matters to you and what your floor allows. We assess the framing before quoting so the curbless-or-curbed call is grounded in your real home.
Choose curbless if
- Accessibility or aging in place is a priority now or for the future.
- You want the most modern, seamless, open look.
- We are already opening the floor, or the framing allows a recessed base.
- You want a shower that is easy to walk, roll, or step into safely.
Choose a curbed shower if
- You want to control cost on the shower base.
- The existing floor structure does not easily allow a recessed base.
- Accessibility is not a driving concern for your household.
- You prefer a straightforward, proven detail in a lighter remodel.
Whether curbless is easy or involved comes down to your floor. A curbless base needs the shower area to sit slightly lower than the surrounding floor so it can slope to the drain. In new construction or a full gut where we are already into the framing, that is straightforward. In many of Kansas City's older homes — with dimensional-lumber joists and existing subfloor — going curbless can mean recessing or reframing the floor, which is real work worth planning for up front.
This is exactly why a curbless shower pairs so naturally with an accessible, aging-in-place bathroom: if you are building for safety and independence, the flush entry is the centerpiece, and it is worth the floor work to get it right. We build the sloped base to the tile industry's ANSI A118.10 waterproofing standard and typically use a linear drain along one wall to keep water in the shower without a curb.
If accessibility is not a factor and you are doing a lighter remodel over a sound existing floor, a curbed shower is a perfectly good, cost-effective choice — and we still build in grab-bar blocking so the room can adapt later.
