The modern, spa-like bathrooms filling design feeds almost always share one detail: a curbless shower that flows seamlessly into the bathroom floor, with no step to climb over. It looks clean, feels open, and ages gracefully. But that seamless look hides a harder build — and a traditional curbed shower still makes more sense for plenty of Tampa homes.
Konar Bros Tile Co. is a family-run tile installer serving all of Tampa Bay, and we build both. This guide compares curbless and curbed showers on look, accessibility, waterproofing, and cost — and explains why, in Florida, the curbless option in particular demands an installer who waterproofs properly.
What Sets Them Apart
A curbed shower has the familiar raised threshold — a curb a few inches high that you step over to enter. That curb contains the water and is the long-proven, straightforward way to build a shower. A curbless shower (also called zero-threshold or barrier-free) eliminates the curb entirely, so the shower floor sits flush with the bathroom floor and you walk straight in.
The difference in feel is significant. Curbless reads as open, modern, and continuous — the floor tile can run uninterrupted across the whole bathroom, which makes a small space feel larger and a large space feel like a custom spa. Curbed showers create a clearer visual separation between wet and dry zones, which some homeowners actually prefer.
Both can be beautiful, and both can be built with the same tile, niches, benches, and glass. The real differences are underneath — in accessibility, in how water is managed, and in what the install demands. Our free design consultation covers which fits your bathroom.
Accessibility: Curbless Wins
The strongest practical case for curbless is accessibility. With no curb to step over, a barrier-free shower is far safer and easier for anyone with mobility challenges, and it accommodates a wheelchair or shower chair when designed for it. For aging-in-place — letting you stay comfortably in your home as you get older — curbless is the clear choice.
This is increasingly why Tampa homeowners choose curbless even when accessibility isn't a current need. A zero-threshold entry future-proofs the bathroom and removes a common trip-and-fall point for every age, which is worth considering in a forever home.
A curbed shower, by contrast, always has that step to navigate. For most able-bodied households it's a non-issue, but it's a hard limitation if mobility ever becomes a concern. If accessibility or aging-in-place is on your radar, that alone can settle the decision in favor of curbless.
Waterproofing: Why Curbless Demands More
Here's the catch that doesn't show up in the design photos: a curbless shower is harder to build and far less forgiving on waterproofing. Without a curb to contain water, everything depends on a perfectly executed slope toward the drain and a flawless, continuous waterproof membrane that extends well beyond the shower area into the surrounding floor.
That makes installer skill the deciding factor. A curbless shower over a sloppy substrate or marginal waterproofing will let water escape onto the bathroom floor or, worse, into the structure — a serious problem in Florida, where our humidity punishes any trapped moisture fast. This is precisely why we build every shower, especially curbless ones, on a Schluter-grade membrane system. See Schluter vs traditional waterproofing for how we keep the structure dry.
A curbed shower is more forgiving because the curb itself is a backstop against water escaping. It's still built over full waterproofing — we never skip that — but the margin for error is wider. The honest takeaway: curbless is achievable and beautiful, but only with an experienced crew who waterproofs correctly. It's not the place to hire the cheapest bid.
Cost and Practical Trade-Offs
Curbless typically costs more than curbed because of the extra work involved: more substrate prep, a precisely engineered slope, a larger waterproofed area, and often recessing the shower floor into the subfloor so it sits flush. That added labor is real, though it's a portion of the overall shower budget rather than a wholesale price jump — showers run $1,200–$4,500 in our pricing.
There are practical trade-offs beyond cost too. Because there's no curb, curbless showers usually need a larger overall footprint or a properly placed linear drain to keep water from reaching the dry zone, and a well-fitted glass panel or a generous wet area helps contain spray. Curbed showers contain water more easily in a compact footprint, which can make them the better fit for a small bathroom.
Both options carry our 10-year workmanship and waterproofing warranty, so the wet work is built to last either way. Browse our tile services to see what each build includes.
The Verdict: Which Should You Choose?
Choose a curbless shower when you want a modern, open, seamless look, when accessibility or aging-in-place matters, or when you're building a forever home and want to future-proof the bathroom. Just make sure you hire an installer experienced with curbless and committed to proper waterproofing — it's the build with the least margin for error.
Choose a curbed shower when budget is a priority, your bathroom is compact, or you simply prefer a clear separation between the wet and dry zones. It's the proven, forgiving, lower-cost option, and it can be every bit as beautiful with the right tile and finishes.
If accessibility is on your mind or you love the seamless look, curbless is worth the extra investment in the right hands. If not, a curbed shower is a smart, dependable choice.

Frequently Asked Questions
Is a curbless shower better for accessibility?
Yes, clearly. With no curb to step over, a curbless shower is far safer for anyone with mobility challenges and can accommodate a wheelchair or shower chair when designed for it. It's the best choice for aging-in-place and for future-proofing a forever home.
Is a curbless shower harder to waterproof?
It is. Without a curb to contain water, a curbless shower depends entirely on a perfectly executed slope and a continuous waterproof membrane that extends beyond the shower. In Florida's humidity that makes installer skill critical — we build them on a Schluter-grade membrane system, and it's not a job for the cheapest bid.
Does a curbless shower cost more than a curbed one?
Usually, yes. Curbless requires more substrate prep, a precisely engineered slope, a larger waterproofed area, and often recessing the floor so it sits flush. It's a portion of the overall shower budget rather than a huge jump, but it does add labor compared to a traditional curbed build.
Can a curbless shower work in a small bathroom?
It can, but it takes careful design. Without a curb, the shower needs a larger footprint or a well-placed linear drain plus a glass panel to keep water out of the dry zone. In a very compact bathroom, a curbed shower often contains water more easily — we'll advise based on your actual space.
