Why Zero-Threshold Showers Aren’t Always What They Seem

Alright, let me just say this upfront—you know those sleek, magazine-worthy zero-threshold showers everyone seems to want these days? The ones where the bathroom floor just flows seamlessly into the shower? Yeah, they look amazing. But here’s the thing: what looks amazing on Instagram doesn’t always work great in real life.

And here’s why I bring it up. We see a LOT of Houston bathrooms where the tile work was just done wrong. I’m talking about showers that were built like a regular tile floor—same method, same mindset—which is basically a guarantee it’s gonna fail. I’m talking leaks, cracks, bad drainage… you name it. It’s not pretty.

So let’s talk about why that happens, why you should care, and what we do differently at EZ Bath.

Why This Actually Matters

Look, I get it. Nobody’s lying awake at night thinking about grout lines. But here’s why you should care:

• Waterproofing is everything. If the shower pan isn’t done right, water will find a way through. It might not happen tomorrow, but give it a year or two and suddenly you’ve got water under your slab or leaking into the ceiling below.
• Repairs are expensive. Fixing a bad tile job means tearing out the whole thing. You’re basically paying twice—once for the bad job, and again to redo it the right way.
• Resale value takes a hit. Home inspectors can spot poorly built showers a mile away. If the drain isn’t right or the slope is off, it’s a red flag for future buyers.
• Safety matters. A poorly sloped zero-threshold shower can get slick. You’re trading a small step-over for a bigger fall risk.

And here’s a kicker: in Houston, a true zero-threshold shower often means either jacking up the entire bathroom floor or digging into your foundation. Both are doable, but they’re big jobs—and a lot of contractors cut corners instead.

The Problem With Tile in Wet Areas

Here’s the hard truth—tile itself isn’t the problem. It’s the grout. Grout is porous. It absorbs moisture. And the more little tiles you have (like the mosaics you’re forced to use on a zero-threshold for proper drainage), the more grout you’ve got. More grout = more maintenance = more chances for failure.

Too many contractors treat a shower like it’s just another tile floor. Same thinset, same approach. But showers need a different build process. You need:

• Proper waterproofing behind the tile (we use Schluter Kerdi, for example)
• The right slope for drainage—not too steep, not too flat
• A 2-inch drain for showers (you’d be shocked how many tubs-turned-showers still have a 1.5-inch drain… that’s a clog waiting to happen)
• Materials that actually last in constant moisture

If any of those steps are skipped or done halfway, the shower’s on borrowed time.

What We Recommend Instead

Now, I’m not saying zero-threshold is never the right choice. But for most Houston homes, a low-profile shower base with a 1.5-inch step is the sweet spot. Why?

• It’s safe—still easy to step into, even if mobility is a concern
• It keeps water contained without needing to re-slope your entire floor
• You avoid the crazy maintenance of endless grout lines
• And if you do need wheelchair access, we can add a subtle ramp

It’s all about balancing function with style. We’d rather build you something that actually works for the next 20 years than something that looks good for a quick photo and then fails.

A Quick Story From a Homeowner

Susan in Katy called us after her brand-new “luxury” zero-threshold shower started leaking—less than two years after it was installed. The contractor had used the exact same method they use for tile floors. No waterproof membrane. Wrong drain size. By the time she noticed, the water damage had already spread under her wood floors.

We tore it out, rebuilt it with a solid surface base, proper waterproofing, and a low step-in. Now she’s got a beautiful shower that doesn’t leak—and she told us, “I wish I’d just called you guys first. Would’ve saved me a ton of stress.”

FAQs About Zero-Threshold Showers

1. Can you still make a low-profile shower look modern?
Absolutely. With the right materials, it looks just as sleek—and way more functional.

2. Is it possible to do a true zero-threshold the right way?
Yes, but it often requires raising or lowering the entire bathroom floor. Most Houston homes aren’t built for it without major work.

3. What if I really want tile?
We can still do it, but we’ll use proper waterproofing behind it. Or we can do a hybrid—solid surface on the bottom where the water hits the most, tile above for style.
