Can You Build a Curbless Shower on a Slab? Arlington, TX

Drive past Bowman Springs Park or turn down Tiffany Oaks Lane and you’ll see the kind of homes that fill this corner of southwest Arlington: mostly one-story houses on concrete slabs, many still carrying the tub-and-shower combo that went in when they were built. The 2026 U.S. Houzz Bathroom Trends Study, covered by CultureMap Fort Worth in October, found that nearly half of renovating homeowners are making their showers bigger and nearly three quarters are planning upgrades with their future needs in mind, and the curbless shower sits right where those two trends meet. So, can you actually build one on a slab?

Quick answer: Yes, a curbless shower can be built on a slab foundation in Arlington, but the floor has to be handled differently than in a home with a crawlspace. Crews either cut and recess a section of the slab or build up the surrounding bathroom floor so the shower pan can slope toward the drain, typically about a quarter inch per foot. Done right, it drains as well as a curbed shower and is far easier to step into.

Key Takeaways: Can You Build a Curbless Shower on a Slab

  • Slab is not a dealbreaker: a curbless shower works on a slab when the floor is recessed or built up to create fall toward the drain.
  • Drain choice matters: a linear drain along one wall allows a single-slope floor, which is the easiest layout to tile and keep dry.
  • Future needs drive the trend: CultureMap Fort Worth reported in October that the 2026 U.S. Houzz Bathroom Trends Study found nearly three quarters of homeowners are planning bathroom upgrades for their future needs, with low-curb or curbless showers among the top features.
  • Waterproofing is the whole job: without a curb, the membrane, the slope and the glass layout do all the work of keeping water where it belongs.
  • Permits are routine: moving a drain or cutting a slab is permitted and inspected through the City of Arlington, and your contractor handles it.

What makes a shower curbless instead of low-curb?

A curbless shower has no raised threshold at all. The bathroom floor simply continues into the shower, and the slope and drain do the work a curb used to do. A low-curb shower keeps a small lip, often 1 to 2 inches, as a backup barrier.

Why does it matter? Because the lip is exactly what trips a parent with a walker or catches a tired knee at 6 a.m. With holiday guests arriving this month, the flush entry is the feature people ask about first in a bathroom remodel. Southern Home Remodeling builds both versions as part of its bathroom remodeling service in Arlington, and each has its place.

Why does a slab foundation change the plan?

On a slab there is no floor cavity to drop a shower pan into, so the fall toward the drain has to be created by cutting into the concrete or raising everything around it. Many homes in this part of southwest Arlington sit on slab foundations poured over clay soil, and some are post-tension slabs with steel cables in the concrete that must be located before anyone cuts.

Clay adds a second wrinkle. North Texas clay swells when wet and shrinks when dry, so a slab that has been through 30 Texas summers is rarely perfectly flat. Measuring the real floor with a laser before the design is locked is not a luxury here. It is the job.

💡 Good to know: Post-tension slabs are usually stamped near the garage or patio edge with a warning not to cut or core the concrete. If your home has that stamp, the slab gets scanned to map the cables before any recess is cut, or the floor is built up instead.

How do you keep water in a shower with no curb?

Four things hold the water: the slope of the floor, where the drain sits, how the glass is placed, and how far the waterproofing extends past the shower.

The slope is the quiet hero. Most tile setters aim for about a quarter inch of fall per foot, so a 4-foot run drops roughly an inch toward the drain. A linear drain along the back wall lets the whole floor slope in one direction, so larger tiles can be used. A center drain needs the floor to slope from four sides, which forces smaller mosaic tile.

Glass and fixtures finish the job. A fixed panel on the open side and a shower head aimed at the back wall keep spray contained, and crews run the membrane a few feet out onto the main bathroom floor as insurance.

Which floor approach suits your bathroom?

The right approach depends on the slab type, the size of the room and how the bathroom door meets the hall. This is how we frame it during an in-home visit, and it applies to most bathroom remodel projects we see across Arlington and nearby Kennedale and Mansfield.

Approach How the slope is made Good fit Trade-off
Recess the slab Cut concrete, repour lower pan area Conventional slabs, tight ceilings Dust, extra days, cable scan
Build up the floor Raise bathroom floor with mortar bed Post-tension slabs, small baths Small step at bathroom door
Low-curb hybrid Keep a 1 to 2 inch lip Shared hall baths, lighter scope Not fully flush
Pre-sloped foam pan Factory pan set into recess Standard sizes, faster install Fewer custom shapes

The build-up option surprises people. Raising the whole bathroom floor by an inch or so and sloping into the shower avoids cutting concrete entirely, which is why it is the default on post-tension slabs. The price is a small transition at the doorway, which can be ramped. If the shower itself is the main goal rather than the whole room, our shower remodeling work in Arlington covers the same options in a smaller scope.

Does a curbless shower need a permit in Arlington?

In most cases, yes. Cutting into a slab, relocating a drain and changing the water lines are plumbing and structural changes, and that kind of work is permitted and inspected through the City of Arlington. Your contractor pulls the permit, schedules the inspections and meets the inspector, so the paperwork is not something you manage yourself.

That buys you a second set of eyes on the two things that can go wrong unseen: the drain connection under the concrete and the waterproofing before tile covers it. Requirements vary between cities, so a professional assessment of your slab and plumbing is the only way to know what your project will need. Southern Home Remodeling is insured as required by the cities it works in.

A curbless shower follows the same path as any bathroom project, with a couple of extra checkpoints around the floor. Here is how it usually runs for a home in Arlington.

1
Free in-home estimateA project manager measures the room, checks the floor with a laser level, looks for a post-tension stamp and asks how the shower will be used ten years from now.
2
Design and drain layoutDrain position, slope direction, tile size and glass placement are settled on paper before anything is ordered, since each one decides the next.
3
Permit and material lead timesThe permit is filed with the city while glass, tile and the drain are ordered. Custom glass often has the longest lead time.
4
Demolition and slab workThe old tub comes out, the slab is scanned if needed, and the recess is cut or the floor is built up. The rough-in is inspected before anything is covered.
5
Waterproofing and tileThe sloped bed is formed, the membrane is applied and flood-tested, and only then does tile go down. This step decides whether the shower is still dry in year ten.
6
Glass, fixtures and final inspectionGlass goes in, fixtures are set, the final inspection is passed and the shower is run to confirm every drop heads for the drain. Shower-focused projects often take 4 to 5 weeks on site.

To see how a flush-entry shower looks when finished, the 1960s home remodel with a walk-in shower in Bedford shows the same approach in an older house.

Can an older home with cast iron drains handle the change?

Usually, yes, but it deserves a look before the drain is moved. Older homes in and around Arlington built before the 1980s often have cast iron drain lines under the slab, and after several decades those lines can be scaled, rough inside or thinner than they look.

When the drain shifts to suit a linear layout, the new PVC section is tied into the existing line under the slab. If the camera shows the old cast iron is near the end of its life, that is the moment to replace the stretch under the bathroom rather than tiling over a question mark.

💡 Good to know: Galvanized supply lines are a separate issue from cast iron drains. If the pressure at the old shower valve is weak, ask for the supply to be checked at the same time so the new shower head gets the flow it was designed for.

What homeowners near Bowman Springs Park usually run into

The first thing crews see in this part of Arlington is the standard 5-foot alcove with a tub in it, often in both the primary and the hall bath. A curbless shower fits that footprint, but the narrow width means the glass and the drain have to be placed with care so there is room to turn around without soaking the floor outside.

Floors in homes around Serenity Court and Edgewater Court are rarely dead level, for the reasons covered above. That is not a foundation problem on its own, but the tile bed has to be built to the real floor rather than to the plan.

Ventilation surprises people more often than plumbing does. Many existing fans in homes from this era move very little air, and Texas humidity plus a larger, open shower means lingering moisture. A higher-capacity fan on a timer is a small line item that protects paint, grout and glass for years.

Then there are the shutoff valves. Many homes still have the original stops behind the tub valve, and they do not always close fully. Replacing them during the bathroom remodeling service in Arlington is routine.

FAQ

Can a curbless shower be built on a post-tension slab?

Yes, but the floor is usually built up rather than cut. Post-tension slabs carry steel cables that should not be cut without a scan, so crews raise the surrounding bathroom floor with a mortar bed and slope it into the shower. The result is still flush at the shower entry with a small ramped transition at the bathroom door.

How much slope does a curbless shower floor need?

Most tile setters aim for about a quarter inch of fall per foot toward the drain, so a 4-foot shower drops roughly an inch. A linear drain lets the whole floor slope one way, which allows larger tile. A center drain needs four slopes and smaller mosaic tile. The exact fall is confirmed on site with a laser level.

Does a curbless shower leak more than one with a curb?

Not when it is built correctly. Without a curb, the waterproofing membrane, the slope and the glass placement carry the full job, so crews extend the membrane out past the shower and flood-test it before tile. A fixed glass panel and a shower head aimed at the back wall keep splash away from the door.

Do homes near Bowman Springs Park in Arlington need a permit for this?

In most cases, yes. Cutting a slab, relocating a drain or changing water lines in a southwest Arlington home is permitted and inspected through the City of Arlington. Your contractor files the permit and meets the inspector, and the rough plumbing and waterproofing are checked before the floor is covered.

How long does a curbless shower take to build?

Shower-focused projects often take 4 to 5 weeks on site, with slab cutting and curing adding a few days compared with a standard pan. Custom glass usually has the longest lead time, so it is measured early. A full bathroom with new vanity, tile and fixtures runs longer, depending on the scope.
