Tomball 77377 sits about 21 miles from our shop, and wheelchair accessible shower is work we do there regularly.
A wheelchair accessible shower is a floor problem first. Everything else — the valve height, the seat, the bars, the handheld — is solvable in an afternoon of specification. Getting a shower chair to roll into the shower without a lip, over a floor that drains properly, on a slab-on-grade Houston house, is the part that decides the job. There are three ways to achieve it and the right one depends on your slab, your bathroom’s location in the house, and how much floor height you can afford to lose or gain. That decision gets made with the concrete and the framing in view, not from a photograph.
Local building realities
The Gulf Coast determinant is the slab. Slab-on-grade is close to universal in the Houston area, and post-tension construction is standard across the newer suburban stock in Katy, Cypress, and Fulshear. Cutting a post-tension slab without locating the tendons is a structural repair nobody wants to pay for, and it is entirely avoidable — the slab gets scanned first, or we build the floor up instead and never open the concrete at all.
The clay under that slab moves seasonally, swelling in a wet spring and shrinking through a dry summer. A large tiled wet area with a long, uninterrupted floor plane needs real movement joints and appropriate crack-isolation, because a curbless shower has no threshold to interrupt the field and a crack will run.
Then humidity. A roll-in shower is an open, unenclosed wet area used by someone who bathes seated and therefore for longer. The room will hold moisture. Exhaust gets sized to the actual room volume and ducted outside, never into the attic, and it is one of the few items where paying more materially improves how the room ages.
Hard water argues for a handheld with a cleanable face and a valve with serviceable cartridges.
How the job is built
We begin at the door, not the shower. If the entry to the bathroom cannot pass the chair, the shower does not matter. Widening a door, changing a swing door to a pocket or outswing, and confirming the turning space inside the room come first.
Then demo to slab and studs across the whole wet area, because the pan, the drain, and the framing all have to be visible together.
The floor is next and there are three routes. Recess the slab — a saw cut and repour, which on a post-tension slab requires locating the tendons before anything is touched. Build the surrounding floor up so the shower reads flush with the new finished floor. Or a very low ramped threshold where a true zero lip is not achievable. We recommend based on your slab, not by default.
Drain and slope follow. A linear drain against one wall lets the whole floor slope in a single plane, which rolls better than a four-way slope to a center drain and is generally the better choice for a roll-in.
Then continuous plywood blocking across every wall — for the bars, the seat, and whatever gets added later. Plumbing rough-in with a valve set within reach from a seated position, offset toward the entry. Bonded waterproofing membrane over the pan and up the walls, banded corners, and an overnight flood test. Then tile, seat, bars, handheld on a slide bar, and trim.
Cost factors
How the curbless floor is achieved is the single biggest driver. Building the floor up is generally the least disruptive. Recessing a conventional slab is more work. Recessing a post-tension slab adds scanning, engineering input, and careful cutting, and sits at the top.
Whether the bathroom door has to widen, and whether that wall is bearing, is second — a header and temporary support change the job.
Whether the drain relocates is third, and it follows the same concrete logic.
Then the shower’s size, since a roll-in needs enough floor for a chair to enter and turn; tile format, where large tiles on a sloped plane require more cutting and a flatter substrate; and whether you want a linear drain or a center drain.
Fixtures and bars are a small share. People consistently overestimate their impact.
Ranges on this work are wide and driven almost entirely by concrete and structure. A measured site visit is the only honest way to price it.
Working in Tomball
Tomball has an old railroad town at its center and a large amount of newer development around it, so the work changes within a few miles. Near the historic core you will find older wood-frame homes where systems are the real project — electrical service upgrades, replacing failing supply and drain lines, structural repair — with finishes coming after. The master-planned neighborhoods built from the 2000s onward are close to the opposite: sound construction, builder-grade finishes, and homeowners who want a real primary bath, better cabinetry, or a covered outdoor space. North and west of town there is acreage, where private well and septic are common. Hard well water shows itself quickly on new fixtures and frameless shower glass, so it is worth addressing before the bathroom goes in rather than after. Some addresses fall inside Tomball city limits and some in unincorporated Harris County, which determines who reviews and inspects the work.
How a project runs
We start by meeting the person who will use the shower, with the equipment they actually use. Chair width, transfer side, whether a caregiver assists, and reach from seated all drive the layout. If an occupational therapist has made recommendations, we would rather build to those than to a generic dimension.
Then we determine the slab type. If there is no documentation, the slab gets scanned before any plan involves cutting it.
Plan, elevations, written scope, and permits — plumbing, electrical, and structural work is permitted and inspected in the City of Houston despite the absence of zoning, and unincorporated Harris County and Fort Bend run their own processes.
Build: demo, floor method, drain and slope, framing and continuous blocking, plumbing rough-in and inspection, waterproofing with an overnight flood test, tile, then seat, bars, controls, and glass or curtain.
Final walkthrough is a real roll-in with the actual chair.
Common questions
Is a linear drain better than a center drain for a roll-in?
For a roll-in, generally yes. A linear drain lets the whole floor pitch in one direction as a single plane, which is smoother to roll across and easier to tile with larger formats. A center drain requires the floor to slope four ways toward a point, creating ridges that a wheelchair or shower chair feels. Linear drains cost more and, for this application, usually earn it.
What if my slab is post-tension?
Then nothing gets cut until the tendons are located, which is done by scanning. In many post-tension houses the better answer is to build the surrounding bathroom floor up so the shower is flush, rather than opening the concrete at all. That may mean a small transition at the bathroom door, which is manageable. Cutting a tendon is a structural repair, and it is completely preventable with a scan.
How big does a roll-in shower need to be?
Bigger than most people first draw. Commonly cited accessible guidance puts a roll-in at roughly 30 by 60 inches minimum, but a minimum-size shower is hard to use if a caregiver assists or the user needs to turn. In practice, more floor makes the shower easier to use and easier to keep dry, because spray stays well inside the sloped area. We size it around the actual chair and the actual routine.
Can a curbless shower really be watertight without a lip?
Yes, and it depends on three things done correctly: the floor slopes toward the drain across the entire wet area, the waterproofing membrane is bonded and continuous with banded corners, and the shower is large enough that spray does not reach the edge. A linear drain along one wall makes the single-plane slope easier to achieve. An undersized curbless shower with a weak slope is what puts water on the bathroom floor.
